Many wild southern sea otters in California are infected with the parasite Toxoplasma gondii, yet the infection is fatal for only a fraction of sea otters, which has long puzzled the scientific community. A National Science Foundation-funded study identifies the parasite's specific strains that are killing southern sea otters, tracing them back to a bobcat and feral domestic cats from nearby watersheds. The study marks the first time a genetic link has been clearly established between the Toxoplasma strains in felid hosts and parasites causing fatal disease in marine wildlife. The study's results highlight how infectious agents like Toxoplasma can spread from cat feces on land to the sea, leading to detrimental impacts on marine wildlife.

Scientists have recovered the first genetic data from an extinct bird in the Caribbean, thanks to the remarkably preserved bones of a Creighton's caracara in a flooded sinkhole on Great Abaco Island in the Bahamas. Studies of ancient DNA from tropical birds have faced two formidable obstacles. Organic material quickly degrades when exposed to heat, light and oxygen. And birds' lightweight, hollow bones break easily, accelerating the decay of the DNA within. But the dark, oxygen-free depths of a 100-foot blue hole known as Sawmill Sink provided ideal preservation conditions for the bones of Caracara creightoni, a species of large carrion-eating falcon that disappeared soon after humans arrived in the Bahamas about 1,000 years ago. Florida Museum of Natural History researcher Jessica Oswald and her colleagues extracted and sequenced genetic material from the 2,500-year-old C. creightoni femur. Because ancient DNA is often fragmented or missing, the team had modest expectations for what they would find –- maybe one or two genes. But instead, the bone yielded 98.7% of the bird's mitochondrial genome, the DNA most living things inherit from their mothers. The mitochondrial genome showed that C. creightoni is closely related to the two remaining caracara species alive today: the crested caracara and the southern caracara. The three species last shared a common ancestor between 1.2 and 0.4 million years ago. "This project enhanced our understanding of the ecological and evolutionary implications of extinction, forged strong international partnerships, and trained the next generation of researchers," says Jessica Robin, a program director in National Science Foundation's Office of International Science and Engineering, which funded the study.

In a whistleblower complaint filed this week, top federal scientist Rick Bright alleges he was removed from his post for failing to go along with the president's push to promote a drug as a cure for COVID-19.

On Wednesday, Trump dismissed the complaint, telling reporters Bright "seems like a disgruntled employee who's trying to help the Democrats win an election."

"I never met him, I know nothing about him," Trump said, adding that he didn't think "disgruntled people" should work for his administration.

Trump also observed that Bright is being represented by a legal team that represented "other people" – seemingly an allusion to lawyer Debra Katz's representation of Christine Blasey Ford, who testified against Supreme Court Justice Brett Kavanaugh during his confirmation.

Bright's legal team declined to comment.

Bright says he was ousted from his position as director of the Biomedical Advanced Research and Development Authority because he wanted to spend money on safe and vetted treatments for COVID-19 — not hydroxychloroquine. The president has called that common anti-malaria drug a possible "game-changer," but there is no proof that it works for COVID patients, and it has side effects. The Food and Drug Administration ultimately warned against using the drug to treat COVID-19 without "strict medical supervision."

Attorneys for Rick Bright, the government scientist who said he had been reassigned and subsequently filed a whistleblower complaint, say a government watchdog agrees that he should be reinstated to his post.

Bright was serving as director of the Biomedical Advanced Research and Development Authority, which is working on a vaccine to combat the coronavirus.

He said he was ousted from the position last month because he wanted to spend money on safe and vetted treatments for COVID-19 — not on ones without "scientific merit," such as hydroxychloroquine, the anti-malarial drug that President Trump and others had been touting.

Trump on Wednesday called Bright "a disgruntled employee who's trying to help the Democrats win an election."

Bright's attorneys say that the Office of Special Counsel, which hears whistleblower cases, determined there were "reasonable grounds" to believe that his removal was retaliatory and therefore prohibited.

Bright's attorneys say OSC plans to contact the Department of Health and Human Services to request that it put Bright's removal on hold for 45 days so the office can complete its investigation into the allegations.

The OSC said it "cannot comment on or confirm the status of open investigations."

In a statement to NPR, Caitlin Oakley, a spokesperson for HHS, said: "This is a personnel matter that is currently under review. However, HHS strongly disagrees with the allegations and characterizations in the complaint from Dr. Bright."

With the dramatic reduction in car traffic and commercial flights, carbon emissions have been falling around the globe. If the slowdown continues, some are estimating the world could see the largest drop in emissions in the last century.

Still, overall greenhouse gas emissions in the atmosphere are still going up and the decline will likely be smaller than what scientists say is necessary to avoid the worst impacts of climate change.

So far, the effects are just starting to appear. In China, the first country to lock down, greenhouse gas emissions dropped an estimated 25% in February as factories and industrial producers slowed output. That decreased coal burning, which has come back slowly since then.

"A month or two of shelter in place will drop carbon dioxide emissions a few percent here or there, but it won't change the year substantially unless we stay like this for some time," says Rob Jackson, environmental scientist at Stanford University.

The declines are still too small to be read by greenhouse gas observatories around the world, like the one on top of the Mauna Loa volcano in Hawaii, given the natural changes in atmosphere this time of year. Because much of the Earth's land mass is in the northern hemisphere, plants and forests there cause carbon levels to fluctuate as they bloom in the spring, drawing carbon dioxide from the air.

If countries continue shelter-at-home orders, emissions declines could be greater. The U.S. Energy Information Administration estimates U.S. emissions from gas and energy use could drop more than 7% this year, similar to a 2009 decline during the financial crisis.

Worldwide, early estimates put global emissions dropping around 4%. Still, that's less than the 7.6% the U.N. says is needed to avoid the worst impacts of climate change by limiting warming to 1.5 degrees Celsius.

To achieve those cuts, scientists say more fundamental changes are needed, like switching to renewable energy.

"This isn't the way we want to reduce our fossil fuel emissions," says Jackson. "We don't want tens of millions of people being out of work as a path to decarbonizing our economy. We need systemic change in our energy infrastructure and new green technologies."

Still, Jackson says the recent changes are providing useful insights.

"It's as if a third of the cars on the road were suddenly electric, running on clean electricity and the air pollution is plummeting," says Jackson. "It's really a remarkable experiment and it shows the benefits of clean energy."

Updated at 6:14 p.m. ET

The federal scientist who was ousted from his role as director of the Biomedical Advanced Research and Development Authority has filed a whistleblower complaint with the U.S. Office of Special Counsel.

Rick Bright was a high-ranking federal scientist focused on vaccine development and a deputy assistant secretary with the Department of Health and Human Services. Last month, Bright said he was transferred to a "less impactful position" at the National Institutes of Health after he was reluctant to promote the use of drugs such as hydroxychloroquine to treat COVID-19 patients.

In the complaint, Bright alleges a range of government wrongdoing by Dr. Robert Kadlec, the assistant secretary of preparedness and response at the U.S. Department of Health & Human Services, and others. Bright's boss was Kadlec, who in turn reported to HHS Secretary Alex Azar.

At the time of his removal, Bright said he had been ousted because of his "insistence" that the government spend funds on "safe and scientifically vetted solutions" to address the coronavirus crisis and not on "drugs, vaccines and other technologies that lack scientific merit."

Bright says in the complaint that he raised concerns about the need to prepare for the coronavirus in January but encountered opposition from Trump administration officials. He says he was transferred out of BARDA in retaliation.

According to the complaint, relations between Bright and Kadlec had been strained since 2018 or so, when Bright began "raising repeated objections to the outsized role Dr. Kadlec allowed industry consultants to play in securing contracts that Dr. Bright and other scientists and subject matter experts determined were not meritorious."

"Once the COVID-19 pandemic hit, however, Dr. Bright became even more alarmed about the pressure that Dr. Kadlec and other government officials were exerting on BARDA to invest in drugs, vaccines, and other technologies without proper scientific vetting or that lacked scientific merit," the complaint continues. "Dr. Bright objected to these efforts and made clear that BARDA would only invest the billions of dollars allocated by Congress to address the COVID-19 pandemic in safe and scientifically vetted solutions and it would not succumb to the pressure of politics or cronyism."

The complaint alleges that Bright made repeated efforts to get the U.S. government to make adequate preparations for coronavirus, but was stymied by political appointees leading the HHS, including Azar.

HHS did not immediately respond to NPR's request for comment.

Bright says that in an effort to get the word out to the public about the risks associated with hydroxychloroquine, he shared with a reporter nonclassified emails between HHS officials that "discussed the drug's potential toxicity and demonstrated the political pressure to rush these drugs from Pakistan and India to American households." He says Azar and Kadlec removed him from his post within days of publication of an article about chloroquine because they suspected he was the article's source.

Bright says he stopped receiving a paycheck on April 20 and has not been assigned any further duties.

News of the whistleblower complaint was made public by his attorney on Tuesday.

Researchers are on a real-life search for what one calls "the ultimate Pokémon": Zenkerella, an elusive scaly-tailed squirrel that has never been spotted alive by scientists. However, biologists recently found three newly dead specimens that hint at how the "living fossil" has evolved over the past 49 million years.

A recent overview and analysis shows that increasing amounts of gas drilling at Groningen, the largest gas field in Europe, led to a dramatic rise in regional earthquakes between 2001 and 2013. After a reduction in extraction was introduced by the Dutch Government, earthquake numbers started to fall. Statistical analysis reveals that if high extraction rates were resumed, about 35 earthquakes, with a magnitude (M) of over 1.5 on the Richter scale, might occur annually from the year 2021 onwards, including four with a damaging magnitude of over 2.5.

The promotion of diesel-fuelled cars in Europe may not have had the beneficial environmental effects that were expected, research suggests. It has been assumed that they help reduce greenhouse gas (GHG) emissions from the transport sector, but studies show that their fuel efficiency is lower than previously believed, while their black carbon and nitrogen oxides emissions are higher. The consequent reduction in global warming effects from diesel cars may therefore be negligible, perhaps even negative.

According to a new analysis by Swedish researchers, action to reduce the impact of several serious forest diseases is typically taken too late. The researchers call for better communication by biologists of how and why diseases spread, to help minimise economic and ecological losses.

Converting algae into bioenergy is one option being considered to meet future demand for transport energy. However, a recent study suggests that some combinations of cultivation processes and conversion technologies for algae-derived energy consume more energy than is produced, although water use and greenhouse gas emissions are lower for the most promising options compared with bioenergy sourced from switchgrass and canola.
