Life cycles of some insects adapt well to a changing climate: Others, not so much

Some biologists speculate that animals will get smaller with global warming to reduce heat stress. While this may be true of warm-blooded animals, what about exotherms like insects? Thanks to a 65-year-old grasshopper collection, scientists have documented that some species -- those overwintering as juveniles -- got larger over the years, helped by an earlier green spring. Grasshoppers with other lifestyles got smaller. Much of this can be predicted given what biologists know of insect life cycles.

White shark liver is on Australian killer sharks' menu

DNA evidence has confirmed killer whales in Australia hunted a white shark for its liver. Based on DNA analysis from the bite wounds on the carcass of a large white shark washed ashore near Portland in Victoria in 2023, the study identified that killer whales were responsible for consuming the mid-section containing the nutritionally rich liver.

How simple prompts can make partially automated cars safer

A new study finds that prompts do a good job of getting drivers to engage with their environment and take over control of the vehicle when necessary while using partially automated driving systems -- with one exception. If drivers are deeply distracted, these system-generated prompts have little or no effect.

Explaining persistent hydrogen in Mars' atmosphere

The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, researchers think they have a good explanation for a warmer, wetter ancient Mars. Building on prior theories describing the Mars of yore as a hot again, cold again place, a team has determined the chemical mechanisms by which ancient Mars was able to sustain enough warmth in its early days to host water, and possibly life.

Vacations are good for employee well-being, and the effects are long lasting

If you're like many Americans, you probably didn't take all your vacation time this year. Even if you did, it's highly likely you didn't fully unplug while off the clock. But you might want to change that if you want to improve your health and well-being, according to a new review article.

Strong as steel, light as foam: High-performance, nano-architected materials

Researchers have used machine learning to design nano-architected materials that have the strength of carbon steel but the lightness of Styrofoam. The team describes how they made nanomaterials with properties that offer a conflicting combination of exceptional strength, light weight and customizability. The approach could benefit a wide range of industries, from automotive to aerospace.

Myth busted: Healthy habits take longer than 21 days to set in

We're nearly one month into 2025, but if you're struggling to hold onto your New Year's resolution, stay strong, as new research shows that forming a healthy habit can take longer than you expect. Researchers found that new habits can begin forming within about two months (median of 59-66 days) but can take up to 335 days to establish.
