‘Safety in numbers’ tactic keeps Pacific salmon safe from predators
A new University of Washington study that leverages historical data has found unique support for a “safety in numbers” hypothesis by showing that Pacific salmon in larger groups have lower risk of being eaten by predators. But for some salmon species, schooling comes at the cost of competition for food, and those fish may trade safety for a meal.

Top predators could ‘trap’ themselves trying to adapt to climate change, study shows
A study led by University of Washington researchers shows that over a 30-year period, African wild dogs shifted their average birthing dates later by 22 days, an adaptation that allowed them to match the birth of new litters with the coolest temperatures in early winter. But as a result of this significant shift, fewer pups survived their most vulnerable period because temperatures during their critical post-birth “denning period” increased over the same time period, threatening the population of this already endangered species. It is the first study to show that large mammalian carnivores are making major changes to their life history in response to a changing climate.

Changes in cholesterol production lead to tragic octopus death spiral
After a mother octopus lays a clutch of eggs, she quits eating and wastes away; by the time the eggs hatch, she is dead. Some females in captivity even seem to speed up this process intentionally, mutilating themselves and twisting their arms into a tangled mess. The source of this bizarre maternal behavior seems to be the optic gland, an organ similar to the pituitary gland in mammals. For years, just how this gland triggered the gruesome death spiral was unclear. But in a new study published May 12 in Current Biology, researchers from the University of Washington, the University of Chicago and the University of Illinois Chicago show that the optic gland in maternal octopuses undergoes a massive shift in cholesterol metabolism, resulting in dramatic changes in the steroid hormones produced. Alterations in cholesterol metabolism in other animals, including humans, can have serious consequences on longevity and behavior, and the team believes this reveals important similarities in the functions of these steroids across the animal kingdom — in soft-bodied cephalopods and vertebrates alike.

Astronomers discover a rare ’black widow’ binary, with the shortest orbit yet
The flashing of a nearby star drew the attention of a team of astronomers, who discovered that it is part of a rare and mysterious system. As they report in a paper published May 4 in Nature, the stellar oddity appears to be a “black widow binary” — a type of system consisting of a rapidly spinning neutron star, or pulsar, that is circling and slowly consuming a smaller companion star, as its arachnid namesake does to its mate.

Scientists find elusive gas from post-starburst galaxies hiding in plain sight
Scientists once thought that post-starburst galaxies scattered all of their gas and dust — the fuel required for creating new stars — in violent bursts of energy, and with extraordinary speed. Now, a team led by University of Washington postdoctoral researcher Adam Smercina reports that these galaxies don’t scatter all of their star-forming fuel after all. Instead, after their supposed end, these dormant galaxies hold onto and compress large amounts of highly concentrated, turbulent gas. But contrary to expectation, they’re not using it to form stars.

Heavens need environmental protection just like Earth, experts say
Space urgently needs special legal protection similar to that given to land, sea and atmosphere to protect its fragile environment, argues a team of scientists. The scientific, economic and cultural benefits of space should be considered against the damaging environmental impacts posed by an influx of space debris — roughly 60 miles above Earth’s surface — fueled by the rapid growth of so-called satellite mega-constellations. In a paper published April 22 in Nature Astronomy, the authors assert that space is an important environment to preserve on behalf of professional astronomers, amateur stargazers and Indigenous peoples.

Lasers trigger magnetism in atomically thin quantum materials
Researchers have discovered that light — from a laser — can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons “spins,” which have a potential applications in quantum computing. Scientists discovered that electrons within the material became oriented in the same direction when illuminated by photons from a laser. By controlling and aligning electron spins at this level of detail and accuracy, this platform could have applications in quantum computing, quantum simulation and other fields. The experiment, led by scientists at the University of Washington, the University of Hong Kong and the Pacific Northwest National Laboratory, was published April 20 in Nature.

Solar energy explains fast yearly retreat of Antarctica’s sea ice
Sea ice around Antarctica retreats more quickly than it advances, an asymmetry that has been a puzzle. New analysis shows that the Southern Hemisphere is following simple rules of physics, as peak midsummer sun causes rapid changes. In this respect, it seems, it’s Arctic sea ice that is more mysterious.
