Europa may be covered in layers of dangerously fluffy ice

Water erupting onto the surfaces of icy moons like Europa and Enceladus may freeze into surprisingly fragile, fluffy layers that could pose a hazard for future spacecraft landings.

That’s the conclusion of a new lab experiment that recreated the near-vacuum conditions on the moons. Researchers placed water inside a large vacuum chamber and lowered the pressure and temperature to mimic conditions in the outer Solar System. Instead of freezing solid right away, the water first boiled. Thin ice crusts formed over the surface while vapor bubbled through them, building stacked, porous layers resembling phyllo dough or a wasp nest.

On Earth, the brittle material grew about 20 centimeters thick. But in the weak gravity of Jupiter’s moon Europa, researchers estimate similar layers could reach several meters thick—and perhaps 20 meters on Saturn’s moon Enceladus. A lander spacecraft could potentially punch through the fragile crust.

Scientists think the ice may form where cryovolcanoes spill water from subsurface oceans onto the surface. If so, NASA’s Europa Clipper spacecraft may be able to spot the material using radar when it arrives at Jupiter in 2030.

Scientists stress-test a wireless polygraph device

By continuously monitoring physiological signs of stress, this wearable patch can detect underlying stress in individuals, including babies, who cannot communicate. john a. rogers/northwestern university

Polygraphs may be best known for high-stakes interrogations, but their real trick is measuring stress. Traditional systems require a spaghetti pile of wires strapped across the body, which makes them awkward for routine use in hospitals and sleep studies. To untangle this problem, researchers built a lightweight, wearable polygraph patch that sticks to the chest and monitors the body’s signs of stress in real time.

The soft wireless device packs in sensors for heart activity, breathing, sweat response, skin temperature, and heat flow linked to blood circulation. Together, those signals help reflect the “multidimensional” nature of stress, study co-author John Rogers said in a statement, adding that the team “crammed as many sensors of physiological processes into this device platform as we could.” The system, which weighs less than 8 grams, runs for over a day while sending data to a smartphone or tablet; machine learning algorithms continuously look for stress signatures.

To evaluate the patch, researchers tested it in mock lie-detector interviews, cold water challenges, pediatric sleep studies, and emergency room simulations. In one notable result, medical trainees who showed bigger spikes in stress tended to perform worse during high-pressure scenarios. The patch could one day help clinicians monitor stress in patients too young or sick to verbalize what they’re feeling, the team said.

Identical errors in more than 200 papers raise red flags

Last year, a colleague sent forensic metascientist James Heathers of the Medical Evidence Project a dozen papers that seemed weirdly similar to one another, hoping Heathers could identify the problem. Heathers noticed that all the papers shared some odd typos, spelling mistakes, and phrases, such as “Kolmogorovor information complexity,” which misspells the last name of mathematician Andrey Kolmogorov.

When Heathers searched for these phrases in Google Scholar, he found about 200 more papers that shared multiple features with the original 12 he analyzed. That’s statistically improbable, unless they all have the same source, says Heathers, who presented the findings last week at the World Conference on Research Integrity in Vancouver. He suspects they’re all variants of the same paper, churned out and sold by a paper mill—an organization that produces fabricated papers and sells them to scientists eager to boost their publication record. Further investigation is required to determine whether the “accidental watermarks,” as Heathers calls the errors, represent intentional misconduct, as the errors could also arise through legitimate use of the same translation software or editorial service.

Searching for other accidental watermarks—a process that could be automated using simple tools, such as spelling and grammar checkers and search engines—could help flag additional potentially problematic papers, Heathers said, and journals could screen submissions so they aren’t published in the first place. The approach is probably catching human mistakes that will become less common amid the rise of generative AI. Still, it’s worthwhile, Heathers said: “You find the bug, you kill the bug.”

A future where drones deliver food and packages to your door, once the stuff of science fiction, might not sound so outlandish nowadays. But a major barrier remains: These machines still require an extensive amount of memory and computing power to find their way.

To help flying robots navigate on their own, the authors of a new Nature study took inspiration from one of nature’s most efficient delivery systems: honeybees. These industrious insects typically conduct a short learning flight before undertaking a broader search for nectar. Then, when tiny errors build up as they track the direction and speed of their travels, they can recognize their home turf from a variety of approaches.

The team sent their drones off on a similar learning flight, during which they took panoramic images of their environment. Then, a neural network processed the images so that the drone could always estimate how to return back home, even if its speed and distance tracking failed.

The method, nicknamed “BeeNav,” was a hit: In all indoor flights and 70% of windy outdoor flights, the drones made it home. An outdoor flight even covered 600 meters while using only 42 kilobytes of data—less than a thousandth of a percent of the data storage in a standard smartphone. The researchers envision such bee-inspired bots monitoring crops in greenhouses or tracking inventory in warehouses.

“What I find especially exciting is how little computation is needed,” mechanical engineer Sarah Bergbreiter, who wasn’t involved in the new study, told Scientific American. “For the small-scale robots that my group and others work on, this is the kind of approach that makes serious outdoor deployments plausible.”
