On a blazing hot day in South Africa, female southern pied babblers can’t think straight. The medium-sized black-and-white birds are trying to get at tasty mealworms behind a see-through barrier. On cooler days, the birds can quickly figure out that all they have to do is go around the small wall of plastic. But when the mercury goes up, the birds just keep stubbornly pecking at the barrier.

That experiment is part of a growing body of research showing that animals get their minds muddled during heat waves. When it’s hot outside, birds struggle to learn, dogs bite more often, goat-like chamois pick fights. This is bad news not just for those who get on Fido’s toasted nerves. If the animals can’t stay alert enough to find food or avoid predators, their chances of survival go downhill, says Amanda Ridley , a behavioral ecologist at the University of Western Australia who coauthored the pied babbler study.

With climate change making heat waves more common, such cognitive impairments across the animal kingdom could ripple through entire ecosystems, putting already fragile species at greater risk. If pollinators forget which flowers to visit, crops and wild plants may fail. If birds can’t find food as easily, their young may not survive. And on a warming planet, a sharp mind is particularly vital. “A changing climate means that your ability to behaviorally adapt is even more important,” Ridley says.

Stanley Plotkin, 93, was instrumental in developing a number of vaccines over the course of his career. He recently said that he’s “beginning to regret having lived so long—because we’re going downhill.” How could we possibly have gotten here?

Maybe we’ve always been here. It turns out that the anti-vaccine arguments currently flooding the Internet have been around for as long as vaccines have. In his new book A Pox on Fools , Thomas Levenson breaks them down into three categories, as made clear in the book’s subtitle: “The True Believers, Grifters, and Cynics Who Convinced Us to Reject Vaccines.” The accusations these people levy against vaccines can just as easily be used to categorize the arguments themselves: They are wrong, they are bad, and they are intolerable.

Wrong

As Levenson tells it, in the early 18th century, a couple of forward-thinking Westerners learned about inoculations against smallpox from Ottoman women and an enslaved African. At that point, infectious disease was by far the leading cause of death, as it had been forever. In the 19th century, roughly 40 percent of babies died of infection before they turned 5.

At a virtual public comment hearing hosted by the US Environmental Protection Agency on Thursday, a long line of environmental advocates voiced strong opposition to proposed new regulations weakening requirements that utilities must follow in cleaning up toxic coal ash residue at hundreds of sites across the country at which coal was burned to produce electricity.

“The Trump administration has jeopardized the nation’s drinking water supplies as a favor to polluters,” Lisa Evans, senior counsel at Earthjustice and a former EPA attorney, said in a statement. “It’s just not right.”

The Trump administration announced in April that it would repeal a rule put in place in 2024 by the Biden administration’s EPA that required utilities to monitor coal ash sites at inactive coal plants. The Trump EPA also said it would loosen requirements for protecting groundwater near those sites. Now the Trump administration wants to rely on states for coal ash monitoring and enforcement and enable them to bypass national standards in some cases.

Last August, the Trump administration issued an executive order intended to fundamentally alter how grant funding is handled by the US government. Under the system that had made the US a scientific superpower, peer reviewers rated the scientific quality and feasibility of grant applications, and subject-matter experts within the funding agencies used these ratings to determine which grants got funded. Under the proposed rules, political appointees would have the final say, and they were specifically instructed not to "routinely defer" to peer reviewers.

In the interim, the administration has lost many court cases because it turns out that issuing executive orders doesn't circumvent legal requirements , and the orders can be vacated if they lack strong justification. To avoid that same fate, the Office of Management and Budget (OMB) has decided to merge the executive order with other administration priorities and send it through the formal federal rulemaking process.

The result is a horror show for US science research. Not only is peer review made a secondary consideration, but the new rules would allow any federal agency to cancel any grant at any time based on the vague assertion that it isn't in the "national interest." The document would also ban any grants on a number of culture war topics, limit international collaborations, and block spending on things like publishing papers and attending conferences.

The Trump administration is refusing to repatriate Americans exposed to Ebola amid the outbreak still raging in the Democratic Republic of the Congo. But the plan to send US citizens to Kenya has hit a snag, and officials are still scrambling to find other countries that might take them.

Earlier this week, it was revealed that the administration had devised a plan to establish a makeshift quarantine and treatment facility in Kenya—instead of bringing its citizens home for high-quality care at specialized facilities built for this purpose . According to the initial plans, the US facility would be in Laikipia, about 120 miles north of Nairobi, where the US has an air base. Initially, the plan was to set up a 50-bed quarantine facility that was expected to be operational today, May 29. Then, in a second state, officials would set up isolation and biocontainment units to house Americans infected with the virus.

But after a series of events on Thursday and Friday, that plan has now been stalled. The Katiba Institute, which advocates for Kenyans' constitutional rights, filed the petition on Thursday to challenge the establishment of the quarantine and treatment facility.

Authorities in the Netherlands said they dismantled a botnet that comprised more than 17 million devices and were managed by 200 servers in a joint operation by the police and the National Cyber Security Center.

The action, announced Thursday , came about after a security researcher reported the sprawling network to authorities. The host infrastructure was located in the Netherlands.

Used for criminal purposes

“The police then seized several botnet servers from a hosting provider for investigation,” the NCSC said. “The botnet was taken offline by the provider because it was used for criminal purposes.”

For years, anti-vaccine Health Secretary Robert F. Kennedy Jr. and his zealous followers have downplayed measles as " just a rash " and falsely claimed that "Measles outbreaks have been fabricated to create fear."

In 2021, when Kennedy wrote those words, the US recorded just 49 measles cases. Yearly case counts have generally been low since 2000 , when the US declared measles eliminated thanks to a decades-long vaccination campaign. But with the rise of Kennedy and his ilk in the past few decades, that public health triumph is being undone. Vaccination rates have slipped, and large, multistate outbreaks of vaccine-preventable diseases have inevitably come roaring back. Now it's becoming painfully clear once again how wrong Kennedy and his cohorts are about infectious diseases and vaccines.

In a study published yesterday in the Morbidity and Mortality Weekly Report , state and federal researchers provided a detailed postmortem of last year's massive multi-state measles outbreak that mushroomed out of West Texas. The data reveals a disease that's far from just a rash, with about 20 percent of people—mostly younger children—being hospitalized.

Some viewers were disappointed that the second season of House of the Dragon ended not with a bang, but a whimper. But the big battle sequence that season 2 set up will open season 3 with a bang, judging by the latest trailer, which has all the dragons, fire, and blood Westeros is known for.

(Spoilers for first two seasons below.)

As previously reported , the series is set nearly 200 years before the events of Game of Thrones, when dragons were still a fixture of Westeros, and chronicles the beginning of the end of House Targaryen’s reign. The primary source material is Fire and Blood , a fictional history of the Targaryen kings written by George R.R. Martin. As book readers know, those events culminated in a civil war and the extinction of the dragons—at least until Daenerys Targaryen came along.

The eight broadcast TV stations owned by ABC filed applications for early license renewals under protest yesterday, accusing the Federal Communications Commission of trying to suppress speech as part of "an unprecedented attack on a single company’s entire portfolio of broadcast licenses."

FCC Chairman Brendan Carr has repeatedly threatened to revoke broadcast licenses from President Trump's least favorite networks. He recently ordered the Disney-owned ABC to file early license renewal applications for all of its TV stations over allegations that its diversity, equity, and inclusion (DEI) practices violate anti-discrimination rules.

"The only plausible reason to issue the Order is to punish the Station for speech the government does not like," ABC said in its filings. The FCC is "using the license process renewal to punish a broadcaster for its editorial choices" in "an extraordinary demonstration of power and coercion directed at disfavored editorial voices," it said.
