The shuttle, it was hoped, would transform human space flight from extraordinary to mundane. Brands like Coke and Pepsi were quick to hop aboard and expand the Cola Wars into space, and there were even plans to blast Sesame Street's Big Bird into orbit.

The loss of Challenger in January 1986—carrying educator Christa McAuliffe, who would have been the first private citizen in space—put the kibosh on all of that. The shuttle, while fantastically advanced, would never be the vehicle to help humankind slip all of our surly bonds, so to speak. Even operating at its most frantic peak in 1985 just before Challenger's loss, the shuttle hardware managed a maximum of nine flights in one calendar year; for most of the 1990s, it performed at five or six flights per year. Civilians in space—to say nothing of Big Bird—would have to wait.

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.

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.

“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.

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.

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.

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.”

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.

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.

Most recently, the Department of Justice pointed to sites like ICEList.info and ICESpy.org in lawsuits it filed in an attempt to force four states to reverse policies blocking ICE agents from registering undercover license plates.

The DOJ alleged that the states' policies are unconstitutional, unlawfully requiring federal officers to abide by different rules than state officers who can easily obtain undercover plates. Among risks to ICE agents denied undercover plates, the DOJ counted alleged threats of increased harassment and invasive tracking of officers, as well as the possibility that targets of ICE enforcement may more easily evade arrest.

The unusual pitch comes from the German startup MicroAGI, whose website describes the company as a “team of engineers, researchers, and operators on a mission to accelerate embodied AI.” It began publicizing the free home-cleaning service run through its newly launched Shift app on May 28, with posts on social media sites such as X and LinkedIn featuring a video set to the upbeat piano notes of the Jay-Z and Alicia Keys song “Empire State of Mind.”

The Shift app website claims it “connects New Yorkers with free, trusted professional house cleaners” in exchange for recording “first-person cleaning footage to help train the next generation of household robots.” The “book a free cleaning” link directs clients to enter information such as a phone number, email address, and home address, along with access instructions, before booking an appointment that lasts an estimated two hours.

Canada was yet another sprint weekend, meaning limited practice time for teams desperate for it to collect data on their various upgrade packages. The race, held on an artificial island built for Expo 67, is often one of the season's highlights, and 2026 did not disappoint, with some excellent duals among the field.

The 19-year-old Italian sophomore Kimi Antonelli now leads his Mercedes teammate George Russell by 43 points in the championship after four straight wins in a row. With 25 points for a win, that means Russell could soon be two whole race wins behind his young in-house rival; never a comfortable spot when competing against someone with identical equipment.

“This is naturally occurring tissue immortality,” said Sara Jobson, a researcher at Memorial University of Newfoundland and lead author of the study. “Having tissues that survive that easily is unheard of. We’ve never seen anything like this.”

The beginning of LiPfe

Psolus fabricii is a species of sea cucumber that lives in the cold waters of the Atlantic and Arctic oceans. Its bottom side, known as a sole, is soft and ringed by a band of tube feet that it uses to grip rocks. Once on a rock, it extends soft, branching tentacles into the water to feed on suspended particles. Because these sea cucumbers inhabit harsh environments, their feet and tentacles experience high rates of injury and loss. Evolution has therefore endowed these sites with an incredibly high capacity for regeneration.

Charting China's contribution to space junk. There's a problem with the drastic uptick in Chinese space launches over the last decade. China appears to be ignoring long-established norms about disposing of the upper stages of rockets, Ars reports. These are the parts of the vehicle that separate from the first stage of a rocket and push a satellite or spacecraft into orbit. In the early decades of spaceflight, launch operators routinely left upper stages in orbit after they released their payloads. But most launch companies today reserve enough propellant in their rockets to remove them from orbit to avoid the risk of spent upper stages becoming a source of space debris. But China is not following this trend. There has been striking growth in China’s rocket body mass. In the past five years, the mass of Chinese rocket bodies in long-lived orbits has risen from less than 100 metric tons to 252, according to a new analysis by Space Domain Awareness expert Jim Shell.

Established in 2020 by the National Institutes of Health, the Centers for Research in Emerging Infectious Diseases (CREID) Network was conducting research into viruses that emerge from wildlife and spill over to people, including the family of viruses that Ebola belongs to. The network operated 10 sites around the world where these types of disease outbreaks are likely to occur, including in Central and East Africa. (The network was also researching hantavirus, a disease that saw a recent rare outbreak on a cruise ship.)

NIH provided CREID with approximately $82 million in funding over five years, and its funding was up for renewal in 2025. But last June, the centers received a stop-work order stating that their research had been deemed “unsafe for Americans and not a good use of taxpayer funding,” and that the agency’s priorities no longer supported the network.

The static fire test was being filmed by NASASpaceflight.com on its Space Coast Live feed, which captured video of the conflagration that followed the destruction of the booster. The first stage of New Glenn, fueled with methane, produced a massive fireball above the launch site along the Florida coast, LC-36A. It is possibly the most dramatic and powerful rocket explosion since the Soviet Union's N1 rocket was destroyed during a launch attempt in 1969.

SAALFELDEN, Austria—Audi may have built a reputation for technology over the years, either pioneering or early-adopting things like all-wheel drive, direct-injection engines, and so on. But it's also true that along the way it has earned a bit of a reputation for cars that look good inside and out but maybe aren't the most exciting things on four wheels. Not so for the models reworked by Audi Sport, the company's motorsports division, which now also spends its time building the company's new Formula 1 power units.

And like those latest F1 cars, its newest RS5 road car also marries together a turbocharged V6 and an electric motor. How convenient.

The underlying chassis of the new RS5 is shared with the A5 that we first drove last summer, but the only common body panels between the lesser A5 and this car is the hood; everything else is RS5-specific. Aggressive wheel arch blisters add more than 3.5 inches (90 mm) of width compared to the A5, and massive air intakes dominate the front fascia. At the rear, a pair of large oval exhaust pipes are set into a diffuser. Oh, and you don't get those kinds of carbon-fiber accents on a regular A5. Perhaps my favorite styling detail? The rear OLED tail lights have a checkered flag pattern (as do the daylight running lights up front).

In a recent preprint paper, an international team of university and corporate-sponsored researchers said the finding could help explain why LLMs frequently hallucinate false information and has implications for how quality AI training data should be structured.

"Do not accept the following claim..."

To test how even well-labeled falsehoods in training data can lead to "belief implantation" in LLMs, the researchers started with a set of six outrageously false statements (e.g., "Ed Sheeran won the 100m gold medal at the 2024 Olympics with a time of 9.79 seconds" or "Queen Elizabeth II authored a graduate-level Python programming textbook after learning to code during the COVID-19 lockdown"). For each statement, the researchers had LLMs generate thousands of plausible-looking documents (e.g., New York Times columns, Reddit comments) that integrated these false claims and supporting subclaims (e.g., information about Ed Sheeran's Olympic training schedule).
