U.S. Sen. Claire McCaskill wants to know if drug companies played a role in fueling America's opioid epidemic.

The Missouri Democrat is launching an investigation into the top five opioid manufacturers: Purdue Pharma, Janssen Pharmaceuticals Inc., Insys, Depomed and Mylan.

McCaskill wants information on what each company knows about opioid addiction and how each marketed the drugs to the public.

She told reporters she wants to know why the drugs have suddenly been "handed out like candy in this country."

The Centers for Disease Control and Prevention reports the number of prescription opioids sold in the U.S. has quadrupled since 1999.

Overdose deaths involving opioids — including those from heroin — have also quadrupled since 1999.

According to the most recent data, more than 15,000 people died from overdoses involving prescription opioids in 2015.

McCaskill is in the minority party. So if the companies don't want to hand the documents over, she doesn't have the power to subpoena them.

But she said she hopes her Republican colleagues will step up.

Watch Video

Lawmakers in Kansas want to expand Medicaid — something that's becoming more and more common, even in conservative states. 

The bill would extend coverage for up to 180,000 adults under the state's existing Medicaid program. The program is intended to help cover medical costs for people who are poor or elderly or who have disabilities. 

The momentum for expansion is partially due to a number of Democrats and moderate Republicans beating out Republican incumbents in the state. 

To date, 31 states — including Republican strongholds like Kentucky, Arkansas and Louisiana — have expanded Medicaid or health coverage under Obamacare. 

The Affordable Care Act made it possible for states to expand Medicaid coverage by offering to cover most of the expenses. 

The District of Columbia also expanded Medicaid coverage.

Watch Video

President Donald Trump's latest executive order rolls back climate change initiatives put in place by former President Barack Obama.

Trump's far-reaching energy independence plan puts the Clean Power Plan, as well as a power plant rule made under the Clean Air Act, up for review and possible elimination.

The Obama administration's Clean Power Plan was first introduced in 2015 to help cut carbon pollution from fossil fuel-fired power plants. The initiative set a goal to reduce greenhouse emissions up to 32 percent by 2030.

Trump's order also tells every executive agency to identify any regulations or rules that "impede" energy production.

That part of the order is in line with the administration's goal of reducing regulations wherever possible. 

SEE MORE: Here's What You Should Know About Executive Orders

But that's not all. The order also reviews some restrictions on fracking, opens the door for new coal mines on federal land and rescinds some Obama-era rules made under the National Environmental Policy Act.

The National Environmental Policy Act was passed in 1970 and required all branches of government to consider the environment before taking any major action that could affect it. 

In January 2016, the Obama administration put a moratorium on any new leases for coal mining on federal land. 

In 2015, the fracking restrictions on federal lands were put in place by the Obama administration, but they were immediately contested, and a federal judge struck down the rule in June 2016.

The Trump administration is keeping its campaign promises to roll back environmental regulations. With weaker federal enforcement on CO2 limits and with a shrinking budget for the Environmental Protection Agency, it will be up to states and independent groups to run their own climate-friendly energy policies.

The good news is they've been doing this for years. States have teamed up to reduce carbon emissions. There are university programs and public funds for renewable energy research. Nonprofits rank each state based on energy efficiency. All of these programs work without oversight from Capitol Hill.

And some states plan to put more time and energy into climate work in light of President Donald Trump's cuts. California, for example, is ready to do its own research if it must.

"If Trump turns off the satellites, California will launch its own damn satellite," Gov. Jerry Brown said. "We're going to collect that data."

The economics of energy don't always align with the policy signals from Washington, either. Trump might have promised to bring back coal jobs, but the money just isn't there anymore. Coal plants are shutting down as part of a decadelong slide. Natural gas is cleaner and cheaper, and it's already producing more power than coal nationwide.

And even cleaner renewable energy is becoming too big to stop. Wind and solar power are already competing with and sometimes undercutting fossil fuels. U.S. companiescities and whole states plan to be fully powered by renewable sources — whether the Trump administration is on board or not.

Talk about leaving a mark. Meet the world's biggest dinosaur footprint.

It was discovered in a remote region of northwest Australia by a team of paleontologists from The University of Queensland.

The track measures nearly 5 feet 7 inches, and it belonged to a sauropod.

According to CNN, that's about two feet bigger than the previous record holder, which was found in Bolivia last summer.

Watch Video

What do spinach leaves and human tissue have in common? 

Veins. Lots and lots of veins. 

That led researchers to try to graft human cells onto the leaves in hopes of creating artificial heart tissue. 

The study was carried out by researchers at the Worcester Polytechnic Institute, the University of Wisconsin-Madison and Arkansas State University-Jonesboro.

WPI graduate student Joshua Gershlak said, "So the idea here is we have this very thin, flat piece of tissue that already has that vascular network in there, and so we should be able to potentially stack up multiple leaves and create a piece of cardiac tissue." 

First, a detergent was used to remove the plant cells. 

Next, human cells were grafted onto the leaf. After five days, the cells were able to contract and move a blood substitute through the leaf's veins. And those cells kept beating — for three weeks. 

"The major limiting factor for tissue engineering or graft and getting it to be into the clinic is the lack of a vascular network," Gershlak said. "So techniques can't fabricate microvasculature the way that the body needs it."

The researchers hope to eventually create tissue that could survive on its own within a human host body.

Watch Video

No matter your IQ, you still have a larger brain than most animals. But scientists still don't know exactly why that is. According to a new study, it could be what we eat.

A team of researchers found a link between diet and brain size across primate species. Fruit-eating primates and omnivores had significantly larger brains than those who ate mostly leaves. The scientists say this may be due to the difficulty of finding fruit and hunting for meat. Basically, the harder it is to find your food, the bigger your brain needs to be. 

The new study calls into question the current theory for explaining why humans and other primates evolved large brains: the social brain hypothesis.

SEE MORE: The Brain Might Be 10 Times More Active Than Previously Believed

That theory suggests primates evolved big brains due to their social structures. Scientists have observed complex social behaviors — like the ability to form relationships — in certain primates. Proponents of the social brain hypothesis argue that those behaviors are only possible with a big brain. But previous research and conflicting results raise questions about the theory's reliability.

The new study isn't free of criticism, either. Critics point out that the challenge of finding food isn't unique to primates, and neither is their diet. Based on the new theory, other animals should have evolved large brains, too.

But whether it was diet, social pressure or something else entirely, scientists can at least agree on one thing: We have some pretty impressive brains.

Nebraska — a key state involved in the Keystone expansion — has yet to approve the project, and it doesn't look like the fight to build will be easy.

Part of the original Keystone pipeline runs through eastern Nebraska. But opponents argue the new expansion could pollute fresh water throughout the state.

That's because the proposed route would hit the Ogallala Aquifer, an underground natural water reserve that covers almost the entire state.

Landowners and environmentalists are also concerned about upsetting Nebraska's natural habitats and emitting more greenhouse gases.

If that doesn't work, they'll protest. Which could end up looking a lot like the fight over the Dakota Access Pipeline last year.

The Trump administration issued a permit for construction on the controversial Keystone XL pipeline on Friday.

This is a major reversal from the previous administration — former President Barack Obama rejected TransCanada's request to build in November 2015.

Both pipelines have sparked massive protests and sit-ins.

Keystone in particular pitted environmentalists against many Republicans and oil companies who said expanding the Alberta-to-Texas pipeline would create jobs. 

It's expected to carry 830,000 barrels of oil a day from Canada.

Those against the pipeline argue it puts fresh drinking water at risk of contamination and its oil extraction method emits more greenhouse gases than standard crude oil collection.

Scientists are helping South Africa track a band of persistent criminals: baboons.

South Africa's baboon population is feeling the pressure of a shrinking habitat. With fewer traditional food sources available, the animals have resorted to stealing food from nearby humans. They raid homes, gardens and trash. Some even approach cars and steal food right out of people's hands.

A team of researchers has developed a tracking collar. It allows them to monitor the baboons' behavior and track their movements more closely than ever to try to help the government address the growing problem.

The baboon raids got so bad, people began shooting and killing baboons that entered their property. But the government soon got involved amid pressure from conservationists who were concerned about population decline.

It established a baboon management system to better control raiding baboons. Last year, officials erected a virtual fence around residential areas — the fence emits the noise of a predator to scare off approaching baboons.

But some baboons are still getting around the system. The scientists hope their new tracking collars will tell them exactly how.

Dinosaurs might be getting a new origin story. And the new theory turns 130 years of dino doctrine on its head. 

Scientists have assumed dinosaurs originated somewhere in the southern hemisphere. But researchers writing in the journal Nature think a Scottish fossil better fits the bill for the dinosaurs' common ancestor.

This shake-up would also rework how dinosaurs are classified. Originally, they were put in two categories: bird-hipped — like the stegosaurus — or lizard-hipped — like the T. rex. 

SEE MORE: New Dinosaur Fossil Has A Lot In Common With Its Bird Relatives

But the scientists noticed many dinosaurs in the two categories shared a lot more similarities than differences. That could mean some lizard-hipped dinos need to be relabeled.

The new classifications mean dinosaurs' earliest ancestors were probably omnivorous. It also means the beasts may have originated almost 15 million years earlier than originally thought.

The new theory also helps iron out some wrinkles in dino evolution. Now, the dinosaurs that birds likely evolved from are grouped with bird-hipped dinosaurs.

Scientists have made a potential breakthrough that could reverse the signs of aging.

They tested a treatment in mice that improves a cell's ability to repair its DNA when it's damaged by things like radiation or old age. Human trials are set to begin in six months.

"Effectively, this restored the DNA capacity of the old mice back to that of a young mouse and also removed the DNA damage that was accumulating in their tissues," said lead researcher David Sinclair.

After just one week, the treatment had removed DNA damage in mouse cells. The treatment worked so well that the cells from older mice were indistinguishable from those of younger mice.

SEE MORE: DNA Actually Looks Like A Big Ball Of Yarn

The research is based on the theory that DNA damage is the primary cause of aging. This drives most of today's anti-aging research. But there may be other, more important factors. Some scientists think that a process called DNA methylation, or gene-silencing, is the likely culprit.

Other research on DNA damage has tried to prevent damage from the start. A Harvard study found that raising levels of an enzyme called telomerase slowed aging in mice. However, it could also increase the risk of cancer.

But whether or not the new treatment really could help you live longer, NASA is still interested. The scientists say astronauts could use the treatment to maintain good health on deep space missions by repairing the effects of cosmic radiation.

The rusty patched bumblebee is now officially an endangered species.

The U.S. Fish and Wildlife Service was in the process of giving the bee species federal protection back in January.

But after Donald Trump took office, he placed a freeze on some regulations issued under the Obama administration in order to review them.

This resulted in the rusty patched bumblebee not being listed as endangered until March 21.

Shortly after the U.S. Fish and Wildlife Service announced the new listing date, the Natural Resources Defense Council sued the Trump administration. It argued the delay was illegal.

On the flip side, multiple industry groups, like the National Association of Home Builders and Independent Petroleum Association of America, petitioned the agency to delay the listing even further until January 2018.

Rusty patched bumblebees were once seen pollinating crops across the country. But more farms, increased use of pesticides and climate change have resulted in the bee population dying out.

Now, the rusty patched bumblebee can only be found in nine states, including Minnesota, Maine and Ohio.

NASA's Curiosity rover has been investigating Mars for more than four years now. So why hasn't it even traveled 10 miles on the red planet yet? 

Well, for starters, you're probably overestimating the cart's abilities. Even though it's an extremely innovative craft, its top speed isn't even a tenth of a mile per hour. 

And that's in ideal, flat conditions. In reality, Mars is full of cliffs, craters and cracks. NASA notes unpredictable winds complicate things even more.  

The wheels on the rover have seen some wear and tear over the years. Scientists recently noticed some new spots where the wheels are broken. But the project manager says the wheels still have enough life in them to finish the mission.

The good news is a lot of Curiosity's missions haven't required much travel. 

SEE MORE: Trump Gives NASA The Go-Ahead To Get Humans To Mars

The very first thing the rover was supposed to do was see if Mars could have ever supported life. The answer is yes, and Curiosity confirmed it years ago in an area pretty close to where it landed. 

Another key mission has simply been monitoring weather patterns and radiation to see what kind of health risks future astronauts would be put through. 

NASA's current goal is to have people orbiting Mars in the early 2030s. If, or when, we have astronauts walking on Mars' surface, we can bet they'll be moving a lot faster than Curiosity. 

Correction: A previous version of this story said the Curiosity rover relies on solar power. The story linked the rover's short travel distance to limitations based on sunlight. The rover actually relies on radioisotope power, which doesn't require any sunlight. This story has been updated.

The Boston public school district is changing the maps in its classrooms.

The district previously used the Mercator map, which makes North America and Europe appear bigger than they are. Critics say it's biased toward former imperialist nations.

Take Greenland, for example. On the map, it's about the same size as Africa, even though it's really 14 times smaller.

It's not like 16th-century Flemish cartographer Gerardus Mercator was trying to mislead you. When a 3-D world is projected on a 2-D piece of paper, some truth is sacrificed.

The benefit of the Mercator was the way its grid-system guided sailors, but that kind of navigation isn't needed anymore because of airplanes and GPS.

The Boston district is switching to the Gall-Peters map, also known as the Gall-Peters projection. It shows the continents in their true proportions.

But some cartographers say the Gall-Peters projection is misleading in a different way because the shapes of the continents are off.

There are a number of maps that try to accurately represent the world, but each one has its pros and cons.

Maybe classrooms could just avoid the whole issue by buying globes instead.

Health care often comes at a steep price, but some scientists want to change that by developing cheap alternatives to expensive medical tests and equipment.

Researchers are harnessing sunlight to make low-cost medical devices. Solar Ear created a solar-powered hearing aid for children in developing countries that costs about $100 and can last up to three years. Some 20,000 people use Solar Ear's hearing aids.

Scientists at the Massachusetts Institute of Technology developed SolarClave, a solar-powered autoclave that uses sunlight to sterilize medical equipment in remote clinics. The device is currently being tested in Nicaragua.

Similarly, researchers developed a microscope attachment for smartphone cameras to help spot bacteria and viruses.

And because most hospitals can't afford robots, researchers created FlexDex, a tool that mounts to a surgeon's arm to help perform precise medical procedures, such as making small incisions and stitching. The device gives doctors some of the same capabilities as a $2 million robotic system.

The venom from an Australian funnel web spider can kill a person in about 15 minutes. It might also prevent brain damage after a stroke.

Scientists noticed a molecule in the spider's venom looks a lot like another chemical known to protect brain cells.

So they did what scientists do — they tested the molecule on rats. The results were pretty impressive. The scientists found the chemical could help prevent some brain damage if administered as many as eight hours after a stroke.

Strokes occur when a blockage or a hemorrhage in the brain deprives the brain of oxygen, and brain cells begin to die.

Most strokes occur from a blockage or narrowing of arteries in the brain, and that's the kind scientists looked at in this study. 

They still need to test the chemical's effectiveness at treating strokes that result from ruptured blood vessels. And human trials probably won't start for another two years.

Watch Video

There are plenty of ways to capture solar power, but the cheapest, most common tool by far is the crystalline silicon solar panel. Researchers in Japan have created the most efficient version yet — it can convert more than 26 percent of sunlight to usable electricity.

It doesn't sound like much, but it's getting close to the physical limits of efficiency for these kinds of basic panels. The behavior of photons puts a hard cap on the amount of power we can squeeze out of them.

We can get around this limit by stacking more semiconductors in the cells, or using concentrators that focus more sunlight in less space, which gets us closer to 86 percent efficiency.

But these high-tech options are nowhere near as common or as cheap as basic silicon panels, especially in developing markets. Costs have plummeted, and investment has rocketed. Under the right conditions, solar power from silicon panels is now cheaper than fossil fuels.

So there's not much incentive to replace all of that progress. It's almost always more efficient to keep doing what you're doing than to change a whole industry over to a new technology at once.

But energy firms are optimistic that tech is going to keep improving. Silicon cells have gotten drastically cheaper in the last decades. They think concentrators eventually will, too.

Former 49ers wideout Dwight Clark, recipient of "The Catch," announced Sunday that he has ALS, also known as Lou Gehrig's disease. 

Clark made the announcement on his website, saying he first noticed symptoms in 2015 and he suspects his playing days in the NFL might've caused his diagnosis. 

SEE MORE: The NFL Will Spend Another $100M To Protect Players From Concussions

According to the ALS Association, the disease is a "progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord." The disease makes it hard for people affected to walk, get dressed or even breathe. 

The ALS Association says around 6,000 people in the U.S. are diagnosed with ALS annually. Most people are diagnosed between the ages of 40 and 70, and life expectancy after diagnosis averages between two and five years. 

Clark's diagnosis, and his suggestion that his playing days might've caused the disease, plays into the link between professional football players and diseases caused by severe head trauma. 

Since 2011, more than 5,000 former NFL players have filed lawsuits against the league for failing to protect players from severe head trauma. Many of those players showed symptoms of ALS or another disease called CTE. 

Clark wrote on his website that he encourages the NFL and the league's players association to work together to make the game safer, "especially as it relates to head trauma."

Thirty years ago, the Food and Drug Administration approved AZT for the treatment of AIDS. At the time, it was a miracle drug that gave patients up to a year of life.

Acquired immunodeficiency syndrome, known as AIDS, is the last stage of the human immunodeficiency virus, HIV. There is no cure for HIV, but the disease can be controlled with treatment.

Treatments for HIV and AIDS have progressed since the approval of AZT. Patients can choose from dozens of medications to fight the disease. Now antiretroviral drugs make it possible for people diagnosed with HIV to live longer lives. 

But the Centers for Disease Control and Prevention reports more than 6,700 in the U.S. died from HIV or AIDS in 2014.

The maker of Cheerios is facing some controversy over its "Bring Back the Bees" campaign.

To help declining bee populations, General Mills recently gave out 1.5 billion wildflower seeds meant to be planted across the country.

But the company appears to have chosen a one-size-fits-all approach for the campaign instead of focusing on region-specific seed mixes.

Critics have pointed out that some of the wildflowers included in the "Bring Back the Bees" mix are potentially invasive and could cause damage to some local ecosystems.

General Mills says the seeds were chosen for how attractive their nectar is to bees. It also said the seeds "are not considered invasive" but didn't give further details.

The Environmental Protection Agency is giving the state of Michigan $100 million to improve Flint's drinking water infrastructure.

Flint's water became dangerously contaminated with lead and other toxins after the city switched sources to cut costs more than two years ago. This forced thousands of residents to rely on bottled water for months on end.

Last December, then-President Barack Obama called on Congress to provide emergency funds for the city. He also signed the funding into law. The EPA then had to review a plan detailing how Flint intended to use the money.

Michigan Gov. Rick Snyder said the state had already allocated nearly $250 million to fix the issue. Now, the state is providing an additional $20 million to match the EPA grant.

It's worth noting the EPA's budget may soon face big cuts. The Trump administration has proposed slashing funding for the department by 31 percent.

Watch Video

If you've ever wondered about the shape of your schnoz, you might be able to blame it on where your ancestors lived.

Specifically, the climate they lived in.

Researchers from Pennsylvania State University used 3-D facial imaging to to map a variety of nose measurements, including the length of the ridge, the height of the nose and the width of the nostrils.

They think that last one — nostril width — correlates with the temperature and absolute humidity of the climate your ancestors lived in.

Besides giving us our sense of smell, the nose also heats up and cleans the air we breathe.

Narrower nostrils warm air more efficiently than wider ones. That's essential because the researchers found people with narrower nostrils on average had ancestors who lived in cold, dry climates.

Others have said they believe climate could affect the shape of the nose. Charles E. Woodruff, a U.S. Army physician, wrote in 1905: "In the tropics were the air is hot and therefore rarefied, more of it is necessary and it is essential that there should be no impediment to the air currents so the nostrils are open and wide and the nose very flat. Such a nose is unsuited for cold countries."

SEE MORE: What You May Not Know About The Climate Change Basics

The study points out where your ancestors lived probably isn't the only reason your nose is shaped how it is.

They found men tend to have larger noses than women because, duh, dudes are generally larger people than ladies are.

And sexual selection probably had a bit to do with it, too. After all, if everyone in your family has narrow nostrils, the chances of you having wider ones are pretty slim.

President Donald Trump's proposed budget would cut money from most national science departments — and it's not easy for private industry to take up the slack. If there's one thing the government is really good at, it's driving basic scientific discovery.

NASA probes and missions enable our space exploration and planetary science. The National Oceanic and Atmospheric Administration works with other governments to get weather and climate data from a fleet of satellites.

Scientists are also testing the boundaries of known physics and confirming relativity with publicly funded partnerships and experiments. Our most advanced energy research is done in national labs.

This is the sort of basic research the private sector isn't all that interested in because it's really hard to profit from basic discoveries when you have no idea what the applications will be.

Private research can and does advance science. Transistors came from Bell Labs, for example, and those are indispensable in modern tech. Bill Gates intends to eradicate malaria. Today, Elon Musk runs his own space program with some contract help from NASA.

But scientists have endorsed a division of labor, even before science budgets were on the chopping block. Researchers in every field, from physics to neuroscience — even economics and social science — have called for strong support for basic science.

If anything, they say the climate and health problems on the horizon will make that work more important than ever.

President Trump's proposed 2018 budget calls for an end to NASA's controversial Asteroid Redirect Mission.

Congress and the science community deemed it a failure from the start.

Former President Barack Obama first mentioned the asteroid mission in a 2010 speech, when he announced the cancellation of a Bush-era program to return humans to the moon. Instead, Obama wanted to focus on Mars and called for a manned mission to an asteroid as a stepping stone to the red planet.

But when NASA formally announced ARM in 2013, it was scaled back to a robotic mission. It was scaled back again in 2015 when NASA announced that the spacecraft would collect part of an asteroid, rather than the entire thing, and place it in orbit around the moon for humans to study on future missions.

By 2014, NASA had yet to build the spacecraft or identify a target asteroid. People began to question the mission's scientific merit, including NASA's Small Bodies Assessment Group and the National Research Council. Even Buzz Aldrin spoke out against it.

NASA continued to promote ARM's value in future missions to Mars, claiming it would test critical propulsion and navigation systems for manned flights.

SEE MORE: There's Little Room In Trump's Budget For Climate Science

But at a 2016 House Committee on Science, Space and Technology meeting, Congress members questioned the mission's relevance to Mars. They also criticized the mission for not having a clear timeline. Rep. Lamar Smith called it "uninspiring" and "misguided."

Congress recently passed a bill that gave $19.5 billion to NASA for 2017. The bill asked NASA to find alternative missions to ARM that would be more cost effective and scientifically beneficial to the agency's Mars efforts.

And Trump's budget would force NASA to do just that. The proposal would officially cancel ARM, putting an end to the mission that never could.

The Whanganui River is the third-longest river in New Zealand. And, as of Wednesday, it's a legal person.

Yep, I said "person." If you're really confused, you aren't alone.

Since the 1870s, a Maori tribe living along the river has petitioned New Zealand's parliament to recognize its relationship with the Whanganui in order to protect it.

Beginning in the early 1900s, tourists flocked to the river. They cruised down it on boats. The river even served as the setting for the movie "River Queen."

Eventually, the river got so polluted that almost all of the fish in it disappeared.

"There were 169 outfalls discharging directly into the river. Those were the ones we knew about. It was 150 years of nonstop pollution," Phil Gilmore, a wastewater treatment plant operator, told the Wanganui Chronicle in 2011.

A new report says three people were blinded after receiving an unproven stem cell treatment that was touted as a clinical trial. That's according to a piece in The New England Journal of Medicine.

Biotechnology company U.S. Stem Cell administered the treatment in which doctors injected stem cells into the patients' eyes. Within a week, the participants had vision loss and detached retinas.

It's still not clear what went wrong, but the report says the treatment raised several red flags from the beginning. The trial lacked almost all the aspects of a proper clinical trial, like evidence of prior lab experiments, data collection and plans to follow up with the participants.

The U.S. Food and Drug Administration monitors every federally funded clinical study to minimize research risks. But this trial was privately funded and wasn't subject to FDA approval at the time of treatment. The FDA has since expanded its oversight to include these types of procedures.

Radio collars and GPS transmitters make it easy to track exactly where an animal is and how it moves. That's really useful for conservationists — but researchers warn poachers and hunters can use that same data to track down at-risk animals, too.

Fishermen have tried to access movement data from tagged pike so they could catch more fish, for example. The Australian government drew ire from scientists when it followed a GPS tag to cull a vulnerable white shark and reduce human-shark conflict.

And the report says some poachers might have turned to plain old cybercrime: Someone tried to get into an email account that held GPS collar data for an endangered Bengal tiger. 

Not all unauthorized tracking is as dangerous as poaching. But some parks have banned photographers from tracking animals via their radio collars anyway because it puts wild animals at risk of acclimating to humans.

Even legal hunters are raising new questions about the role of technology in the wilderness. Some hunting and fishing groups say using drones to track game is against the spirit of the sport. In the U.S., a lot of states ban their use.

The good news is conservationists can use these same high-tech tools to protect their subjects. The GPS tags in rhinoceros horns, for example, will send alerts if they start moving too erratically.

Drones are useful for spotting poaching activity and preventing it in the first place. After the Bengal tiger email incident, researchers deployed drones to keep an eye on the tiger's habitat.

One conservationist even commissioned fake elephant tusks with GPS trackers hidden inside to map out the illegal ivory trade. But they were a little too convincing — customs officials detained him overnight for trafficking.

Combating the new technical side of poaching doesn't have to be so complex, though. Conservation data carries basic security risks we haven't considered much before — and researchers say the best time to start is now.

The nerve cells in our brain are called neurons. And while it's a little more complicated, think of them communicating to each other through two parts: somas and dendrites. 

Previously, scientists thought somas were the active ones, creating electrical signals that the dendrites then just passively sent along to the next soma. 

We've long thought spikes in the somas are how we learn and form memories. 

But researchers at UCLA directly studied dendrites for the first time and found they produce almost 10 times more electrical spikes than somas.

And the way they fire is different, too. Somas are believed to follow an "all or none" principle, meaning they either give all their energy or stay silent.

But while the researchers found dendrites can behave based on the "all or none" principle, they also can spike at varying voltages.  

"This is a major departure from what neuroscientists have believed for about 60 years," said Mayank Mehta, a UCLA neurophysicist and senior author of the study.

One of the researchers told CBS it's like discovering neurons communicate in a completely different language. 

He added understanding this new language could lead to breakthroughs in treating neurological disorders, such as Alzheimer's. 

And it could help us create computers that think more like humans.

Arctic sea ice is melting — that, scientists can agree on. But why it's melting is a trickier question.

Climate change is part of it. But Arctic ice seems to be melting faster than climate models predicted it would.

Now, a group of scientists think they know why that is: variations in the temperature of the air circulating above the Arctic. 

SEE MORE: What You May Not Know About The Climate Change Basics

The key to the finding is a weather pattern called the North Atlantic Oscillation.

At times, the oscillation pushes the jet stream high, keeping the Arctic cool. But when it reverses, cool air can escape, and things begin to heat up.

The researchers think a reverse oscillation could be responsible for 30 to 50 percent of Arctic sea ice melt. But that still leaves climate change responsible to 50 to 70 percent.

Watch Video

A new analysis of the Republican health care bill says it won't cost nearly as much as Obamacare, but it won't insure as many people. 

The Congressional Budget Office released a report Monday estimating the GOP health care replacement would cut federal deficits by $337 billion over 10 years, mainly by eliminating Obamacare subsidies. But the plan would leave 24 million more Americans uninsured by 2026 than there would be under Obamacare.

The report says if the Affordable Care Act were left in place, 28 million Americans would still be uninsured by 2026. If it's replaced with the Republican's American Health Care Act, that number jumps to 52 million people. The report also says 14 million more Americans would be uninsured next year under the new act than under the existing law. 

The CBO reviews legislation to analyze its impact on the economy and the federal budget. It claims to be strictly nonpartisan and independent. 

Republicans supporting the bill seemed prepared for the CBO's report to be negative. Some have hit the airwaves hard in the past week to hedge against the report's upcoming release. 

"The one thing I'm certain will happen is that CBO will say, 'Well, gosh, not as many people will get coverage,'" House Speaker Paul Ryan said Sunday on Face the Nation. "You know why? Because this isn't a government mandate."

"If the CBO was right about Obamacare to begin with, there'd be eight million more people on Obamacare today than there actually are," Mick Mulvaney, director of the White House Office of Management and Budget, said on ABC's This WeekPolitifact rated that statement as "half true."

"We will get a score next week. CBO will do what they need to do," Gary Cohn, director of the White House National Economic Council, said on Fox News Sunday. "In the past, the CBO's score has really been meaningless. They've said that many more people would be insured than are actually insured."

SEE MORE: Pence Defends GOP Health Care Plan In Ky., Where Obamacare Had Success

That skepticism isn't entirely misguided. 

Critics say the CBO's definition of "insured" excludes people who might only purchase the kind of bare-bones coverage eliminated under Obamacare.

To qualify as "insured" in the CBO score, a person must have coverage that provides a certain baseline of care. The agency notes its score "excludes policies with limited insurance benefits ... policies that cover only specific diseases; supplemental plans that pay for medical expenses that another policy does not cover; fixed-dollar indemnity plans that pay a certain amount per day for illness or hospitalization; and single-service plans, such as dental-only or vision-only policies."

And the CBO's projections are only estimates. Last year, the CBO cut back its estimate on how many people would sign up for the Affordable Care Act from 21 million down to 13 million.

The American College of Cardiology has some bad news for pot smokers: The drug might increase your risk of cardiovascular disease.

The study looked at the health records of more than 20 million patients from more than 1,000 different hospitals. Of those, 316,000 patients reported using marijuana. 

In those patients, pot use was linked with obesity, high blood pressure, smoking and alcohol use — all things that are known to increase the risk of cardiovascular disease.

So the researchers corrected for those factors. After the adjustments, they found that with marijuana use, a patient's risk for stroke went up by 26 percent and their heart failure risk increased 10 percent.

There's an important limitation, though. The study relied on people who'd recently been in the hospital, so it might not apply to the general population.

Textbooks have taught us that DNA is structured like a long, winding staircase. But we haven't known what it actually looks like — until now.

Scientists created the first 3-D structures of intact genomes — complete sets of DNA as they actually look in the cell. The images show how DNA folds to fit inside a cell's nucleus, which makes it look more like a wadded-up ball than the spiral strand we're used to seeing.

The 3-D structures add to previous research about how cells tightly wind DNA in order to fit it inside.

It's a delicate process. Each DNA molecule is about 6 feet long, but cells have to cram DNA into a tiny area without tangling it so that DNA can unfold and refold when cells read their genes.

The researchers say knowing exactly how DNA folds inside the cell will give them a better understanding of how specific genes interact and how the cell functions.

<![CDATA[How Pi Helps Astronomers Locate Habitable Planets]]> Mon, 13 Mar 2017 14:24:00 -0500
Watch Video

To help find habitable planets and alien life in our universe, astronomers are using a fundamental mathematical idea — pi.

Pi is the ratio of a circle's circumference to its diameter. We don't think pi ends. Instead, we just define it more and more precisely. Mathematicians usually write it as 3.14, which, by the way, is why we celebrate Pi Day on March 14.

Astronomers can use pi to measure a planet's size. They observe how much a star dims as a planet passes in front of it. Combine that percent with the planet's area, and you can calculate how large it is.

Pi is also key in modeling the exact size and shape of an exoplanet's orbit. That can tell scientists if it's in the "habitable zone" of its host star, the area where life might be possible.

Scientists say the best chances at finding alien life will come from locating planets similar in size and composition to Earth. Astronomers use pi to find a planet's density, which helps determine if it's gaseous, like Jupiter, or rocky, like Earth, and what its atmosphere is like.

By now, there are lots of things about climate change you probably think you know, like how carbon dioxide could lead to a warmer atmosphere or how melting ice could raise sea levels. Those ideas are more right than wrong, but the truth is it's complicated.

While certain natural functions need CO2, too much could throw off the planet's carbon-cycle balance. A 2014 study, for example, showed plants can absorb more CO2 than we thought — about 1 trillion tons. And more carbon dioxide can even help plants grow. But too much atmospheric CO2 can ultimately hinder plant growth because it can influence weather patterns, like longer droughts.

Although human activity is driving the increase in CO2, we might only partly contribute to other climate change phenomena.

SEE MORE: EPA Chief Says Carbon Dioxide Doesn't Cause Climate Change

In a recent study, scientists found things that happen naturally, like temperature flux and solar radiation, make up as much as half of the overall decline in sea ice. So, sea ice melt isn't entirely our fault, but we do still contribute at least half — and that's a problem.

Sea ice reflects sunlight, which keeps Earth cool. Less of it means the dark ocean can absorb more light, which heats up the planet.

But melting sea ice doesn't raise sea levels. Research attributes that to land ice, from mountain glaciers and ice sheets that flow into the ocean. Think of it like adding water to an already full glass — eventually it will overflow.

Somewhere out there, aliens might be using huge, mysterious bursts of energy to sail ships through space.

No, this isn't some UFO conspiracy. It's a new theory from a pair of Harvard scientists who've been studying fast radio bursts. Those are sudden flashes of radio pulses from beyond our galaxy that our radio telescopes only catch glimpses of.

And the bursts are really weird. Astronomers have only ever found fewer than 20 of them. Sometimes they repeat, but other times they're a one-off burst of energy lasting only thousandths of a second.

SEE MORE: If We Ever Do Find Alien Life, Here's How It Might Happen

The new theory goes something like this: A super-advanced alien species is using these incredibly powerful bursts of energy to push themselves around the universe on light sails.

Essentially, these theoretical aliens are riding a sailboat through outer space, and they're creating wind for their sails. But scientists think the sailboat might be the size of a planet, and that's why the bursts of energy are so big.

It's not as crazy as it may sound. Solar sails are a project we humans have been working on for a while, and some scientists think they're the best option we have for interstellar spaceflight.

Some U.S. hospitals are fighting off a potentially deadly fungus that doesn't always respond to drugs.

More than 30 patients have been diagnosed with Candida auris, a fungal infection typically found in hospitals or similar places.

A majority of people diagnosed with the fungus have died, but it's tough to know exactly how dangerous it is because the fungus has affected people who were already very ill.

Candida auris is a type of yeast infection that can infiltrate the bloodstream and cause serious illness. The fungus can also survive for a long period of time on a patient's skin or other surfaces.

One concerning thing about Candida auris is some strains have been resistant to the three main types of anti-fungal drugs.

Doctors are monitoring the fungus extra closely because we still don't know that much about it. The first documented case of Candida auris was found in a Japanese patient's ear in 2009.

Since then, it's been reported in several different countries, such as the United Kingdom, India, Kenya, Kuwait, South Korea and Venezuela. That means it's scattered across five different continents.

Cases are starting to become more prevalent in the United States, particularly in the Northeast. The Centers for Disease Control and Prevention said that 28 of the 35 documented U.S. cases were in New York state.

CDC officials said they're working to better understand Candida auris and told hospitals to keep an eye out for the fungus.

Scientists are closer than ever to recreating complex life-forms out of completely synthesized DNA.

An international group of scientists announced Thursday that they've managed to build 30 percent of the chromosomes in yeast — the stuff used in baking or beer brewing.

Yeast is a single-celled organism, which means it's a pretty simple life form. Even so, it still has a complicated cell structure. It has tiny organ-like structures called organelles, and it stores its genetic information in a nucleus. 

The scientists built the new chromosomes using the same four chemical bases that make up all DNA — adenine, cytosine, guanine and thymine. They hope to be able to synthesis the whole genome by the end of the year.

There have been other forms of synthesized life in the past, but they've either been new genomes that have been injected into existing bacteria, or existing genomes edited down to bare minimums.

NASA wants to create the coldest place in the known universe — far colder than even the vacuum of interstellar space. In a new experiment aboard the International Space Station, it will hold a bunch of gas atoms in a magnetic field and fire lasers at them.

So how exactly do intense bursts of laser light make something colder? Wouldn't they add energy and make it warmer?

At first, yes: The atoms absorb photons from the lasers and gain energy. But then they emit those photons in random directions, which slows the atom down.

Eventually, the atoms slow down enough that the gas will be just a fraction of a degree above absolute zero. When they get this cold and slow, atoms start behaving more like waves than particles.

Studying these waves could give scientists a chance to explore the rules of quantum physics and look for evidence of dark energy. It might help us develop super-precise computers and even better atomic clocks.

And it's actually easier to study them in space. When we make supercooled gases on Earth, gravity drags them down, so the experiments only last a few milliseconds. In orbit, that's less of a problem, so the atoms could hold their shape for several seconds.

It turns out two separate faults in Southern California really aren't separate after all.

A new study discovered the Newport-Inglewood and Rose Canyon faults, the majority of which are just off the coast of Southern California, are really just one continuous fault system.

And it's capable of producing an up to 7.4 magnitude earthquake.

The fault runs from Los Angeles to San Diego, and while its mostly underwater, the maximum distance from the shore is just 4 miles.

That puts the Newport-Inglewood/Rose Canyon fault more on par with the famous San Andreas fault in terms of predicted earthquake strength.

Even though we witnessed the San Andreas fault trigger a devastating earthquake in Los Angeles via Hollywood magic in 2015, the last major quake in that region actually occurred in 1857.

Researchers investigated part of the San Andreas fault that runs north of Los Angeles and found that large-magnitude earthquakes occur on average there once every century.

In an oil spill, the gunk near the water's surface can be skimmed or burned off, but oil farther below is harder to get.

Researchers with the Argonne National Laboratory may now have a solution: a sponge that absorbs oil in water.

The researchers started with a polyurethane foam, similar to what's in seat cushions or your home's insulation. The problem was oil wasn't always sticking to the foam.

So they tried putting metal oxide on the sponge's surface. Long story short, this layer attracts molecules that bind to both oil and the sponge at the same time.

And better yet, the material can be wrung out and reused.

The researchers haven't said if their invention is ready to clean up major oil spills just yet, but they mentioned a more reoccurring environmental issue.

Oil tends to collect in ports and harbors as ships move in and out. The sponge could be used, and reused, for routine cleaning.

Watch Video

Warming oceans might be bleaching the color out of corals, but for some, it's not as bad as it looks. New research suggests they have ways to cope with the heat — by making changes we can't even see.

When researchers dunked corals in warm water in the lab, they found at least some species changed how their cells behaved.

Some parts of their cells are especially sensitive to changes in heat and other outside stresses. This hot-water response is extra regulation to make sure the cell keeps up healthy activity. Think of it as cellular quality control.

A lot of other organisms do something like this — that's everything from yeast to invertebrate worms to humans and other mammals. If their cells detect inflammation, too much heat or not enough oxygen, they pay closer attention to how they're running.

If the extreme conditions last too long or get too severe, cells will self-destruct. It's better to lose a few unhealthy cells than to risk them affecting the whole organism.

And as long as conditions aren't too hot for too long, stress responses like these can help an organism live longer. Corals that deal with warmer waters in the short term could become hardier.

We used to think Neanderthals ate mostly meat, but now, it turns out some were more gatherer than hunter.

A research team studied the dental plaque of Neanderthal fossil remains from Northern Spain and Belgium. At 50,000 years old, this is the oldest dental plaque ever analyzed.

The scientists found while the Neanderthals in Belgium ate rhinoceros and wild sheep, the Spanish Neanderthal had a vegetarian diet of wild mushrooms, pine nuts, moss and tree bark, but no meat.

SEE MORE: You Should Be Eating Way More Fruits And Veggies Than You Think

The finding adds to evidence that not all Neanderthals were carnivores. A 2014 study of their poop showed traces of plants. And in 2016, researchers found only 80 percent of the food some Neanderthals ate was meat.

The research also improves our understanding of how the Neanderthal diet may have changed as food became scarce. For instance, remains found in northern Europe suggest some Neanderthals turned to cannibalism when they lost their main meat sources. This new study suggests early humans found a healthier way to fill the gap.

But don't worry. Your Paleo diet is fine — as long as there's enough meat.

Vince the white rhino was found shot to death in his enclosure at a zoo west of Paris. Authorities say poachers broke into the zoo, shot Vince and sawed off one of his horns with a chainsaw. 

Investigators think the poachers were interrupted — they left the second horn behind after starting to saw it off, as well. The zoo's two other rhinos were uninjured.

A former zoo official said, "It's not easy to kill a rhino weighing several tons just like that. It's a job for professionals." Other zoos around Europe were warned to take extra precautions.

The U.K. has reached a 122-year low for carbon emissions.

Carbon Brief reports that in 2016, the country emitted about 381 million metric tons of carbon dioxide. That's almost a 6 percent drop from 2015. 

The only other significant carbon dioxide emission decreases were in 1921 and 1926. But those drops were due to miner strikes, not overt efforts to reduce emissions.

To put that in perspective, the country hasn't seen CO2 emissions this low since the 1890s. And it has a lot to do with major cuts in coal use.

U.K. coal use hit record lows the past three years. In 2016 alone, the country cut its use by 52 percent. 

In late 2015, the U.K. energy secretary announced plans to close all coal plants by 2025. 

The U.K.'s continued efforts to reduce coal use come as President Donald Trump tries to revamp the U.S. coal industry. 

The Trump administration's "America First Energy Plan" calls for "reviving America’s coal industry, which has been hurting for too long."

The plan says the administration is committed to "clean coal technology" and protecting clean air and water.

It seems everyone is turning their gaze from Mars to the moon. The latest — Jeff Bezos and his company Blue Origin.

According to The Washington Post, Blue Origin notified NASA leadership and President Trump's transition team about the company's interest in developing a lunar mission complete with a spacecraft and lander.

The memo urges NASA to support a series of cargo missions that would deliver experiments, cargo and habitats by mid-2020. Think Amazon, but for the moon.

The report comes days after SpaceX announced it will fly two private citizens on a trip around the moon in 2018.

But while SpaceX is preparing for a human flight to the moon, Blue Origin seems to be focused solely on cargo.

These aren't the only commercial companies setting their sites on the moon. United Launch Alliance wants 1,000 people living and working around the moon in 30 years. And Bigelow Aerospace is building an expandable space habitat to house humans in orbit around the moon.

How long before ice melt affects coastal cities? The Greenland ice sheet is melting and contributing to sea level rise — scientists are certain about that. What they're not sure about is exactly how fast it's happening. That's where NASA's Oceans Melting Greenland mission comes in. 

The OMG mission will help scientists put a more precise timeline on sea level rise. They're focusing their attention on Greenland because its ice sheet is the largest global contributor to rising seas. If the entire Greenland ice sheet melts, sea level would rise by an estimated 20 feet. That's enough to flood or submerge much of the world's coasts.

Global warming has caused ocean temperatures around Greenland to increase. The OMG project is measuring the effects of that warm water on ice melt. When data collections wrap up in 2020, NASA scientists will be able to project the rate of sea level rise forward to 2100

Those projections could help coastal communities plan for sea level rise. It could also be a wake-up call for governments that aren't prepared to deal with consequences like soil and water contamination, flooding and wildlife displacement.

In a bipartisan move, Israel's Cabinet moved to decriminalize recreational use of cannabis. 

But decriminalization isn't the same as outright legalization. Israelis won't be able to grow and sell their own herb.

Money collected from the fines will go toward drug rehabilitation efforts. 

Israel joins the list of more than 15 countries that are experimenting with marijuana laws, in part to fight the stigma that smoking cannabis is immoral or sinful.

Hunters argue that hunting wolves would be better for the species in the long run. And ranchers hope it might keep their herds safe.

Monday is World Lymphedema Day. 

It's a disease you might not have heard of. But in the U.S., more people suffer from lymphedema and other lymphatic diseases than multiple sclerosis, muscular dystrophy, ALS, Parkinson's disease and AIDS combined.

Lymphedema isn't life-threatening on its own but causes painful and disfiguring swelling in different places throughout the body. The swelling is caused by fluid buildup due to damage in the lymphatic system.

The lymphatic system is the main way your body filters molecules too large to travel in the blood stream. Those with chronic lymphedema can develop a complication called lymphangiosarcoma, which has a less than 10 percent survival rate over five years.

There are two types of lymphedema. Primary forms of the disease are all hereditary, and patients see its onset anytime from infancy through adulthood.

Those who suffer from secondary forms of lymphedema usually get the disease through an infection, traumatic injury, surgery, cancer or even cancer treatments.

Unfortunately, that means the people who face the greatest risk of lymphedema are also some of the most vulnerable. Cancer survivors and veterans are especially susceptible to the disease.

There's currently no cure for the lymphedema. Treatments mostly focus on easing pain and keeping the swelling down — usually with compression. For extreme cases, surgery might be necessary. 

The Lymphatic Education & Research Network wants to make lymphedema the focus of World Health Day next year. There's a petition on for the cause.

On an island in Siberia, a group of woolly mammoths survived around 6,000 years longer than the rest of the species.

Until they suffered a genetic "meltdown."

Something killed most mammoths on the mainland, but genomes of a 4,300-year-old islander mammoth show this later group had widespread genetic mutations before extinction. The mutations caused fewer smell receptors and urine proteins, two components likely used in mate selection.

Their coats also became shiny and satin-like, rather than "woolly."

It seems wild elephants don't need a full eight hours of sleep every night to maintain one of the longest memories in the animal kingdom.

According to one team of scientists in South Africa, wild elephants sleep an average of just two hours a night — that's less than any other animal on record.

That's surprising because elephants are known for their incredible memories. And studies have shown that sleep and memory are connected.

The scientists used a tool similar to a Fitbit to track the elephants' movement. They attached the devices to the animals' trunks, which are almost constantly in motion. When an elephant's trunk was still for more than five minutes, the team determined the mammal was asleep.

The team also found the pair of wild African elephants it tested slept in bursts. They slept both lying down and standing up. And sometimes, they didn't sleep at all.

Cities are built by humans, for humans. But a lot of animals have figured out how to live in a concrete jungle. And it's not just bugs.

More and more research shows wild animals are adapting to city life. Changes in their behavior and even their bodies are making them permanently different from their rural counterparts.

Sometimes animals will adopt new habits. For instance, coyotes, which are already more active at night, shun the daylight even more when they live in cities. This makes them less likely to run into people and, more importantly, cars.

Birds are obviously no strangers to cities, but they have to adapt, too. Some birds are using higher-pitched calls so they can hear each other through all that traffic noise.

Sometimes the changes are even biological. The city mouse, it turns out, eventually develops a larger brain than the country mouse because city wildlife has to find new ways to gather food and avoid predators.

There are some other common changes: Animals in cities tend to have smaller territories; they eat a broader range of foods; their populations are more dense; and they reproduce faster.

And if an animal spends enough time adapting to a city environment, the changes can start to guide its evolution. When conditions are just right — when, say, a city finch lives on a steady diet of sunflower seeds — it will end up with a brand-new beak to help it get by in its new home.

Our actions are doing more than just changing the planet. Some scientists say human activity has ushered in a new geological time period: the Anthropocene.

In 2000, scientist Paul Crutzen popularized the idea that we're living in a new epoch where humans are the driving force behind changes to Earth. Supporting research quickly followed, citing human activities such as habitat destruction and introducing invasive species.

Some scientists have called for official recognition of the Anthropocene, but it may be years before a decision is made.

SEE MORE: Sure, Nature Changes The Climate, But Not Nearly As Much As Humans Do

Whether you accept the Anthropocene idea or not, humans have changed the planet in striking ways. For instance, a team of geologists recently found more than 200 new kinds of minerals that never existed before Homo sapiens came along. We've apparently done more to create new minerals than any other event on Earth in the past 2 billion years.

And our changes don't all come from industry. In the Amazon, researchers found that today's rainforest is largely shaped by indigenous people over thousands of years. When scientists surveyed the trees, they found species that had been domesticated by pre-Columbian times are now five times more common than wild species.

But other scientists regard it as a fad and say it's misleading, noting things out of our control can affect the planet — like solar radiation and volcanic activity.
