Phys.org / Asteroid Donaldjohanson wobbles as it rotates, Lucy flyby reveals
Southwest Research Institute (SwRI) scientists studying the inner main-belt asteroid Donaldjohanson have found that its rotation wobbles. Rather than rolling through space in a steady pattern, Donaldjohanson turns on two ...
Phys.org / How sea-ice microbes survive the Southern Ocean's harsh winter has implications for climate change
A study led by South African scientists reveals that during winter, the sea ice around Antarctica harbors a reservoir of microbes, most of which have one thing in common—the ability to produce and break down a compound known ...
Phys.org / Fermi mission uncovers possible sibling supernova remnants
A new study of two supernova remnants, the debris left behind after stars explode, suggests the explosions came from stellar siblings that once orbited each other. The first star's detonation sent its binary companion hurtling ...
Phys.org / Hidden fungus inside desert moss could rewrite 470-million-year story of how plants moved onto land
Mosses are survivors. They can dry into what looks like green dust, only to spring back to life minutes after rain. They can grow on rocks, in deserts, and there's talk of using them to terraform Mars someday. According to ...
Phys.org / Suburban street design has driven emissions since WWII, study suggests
Half of all Americans live in the suburbs. For decades, planners and policymakers have blamed suburban sprawl's environmental and social costs on one thing: distance. The farther people live from city centers, the more they ...
Phys.org / How do flocking birds and schools of fish move? New research offers crystal-clear answer
Flocking birds and schools of fish are a familiar sight. While previous research has uncovered the broad dynamics driving these movements, their underlying intricacies remain a mystery. Now a study by a team of New York University ...
Phys.org / How a telescope's mirror stability makes or breaks exoplanet detection
Finding life beyond our solar system is a major goal of modern astronomy. NASA's planned Habitable Worlds Observatory (HWO) aims to take direct images of Earth-sized planets around stars other than our sun. This task, however, ...
Phys.org / Out-of-equilibrium cesium atoms reveal fractional Fermi seas, exposing new critical quantum phase
In a new study published in Physical Review Letters, a team from the Nägerl group, together with theory collaborator Alvise Bastianello from the CNRS and the Université Paris-Dauphine, demonstrates that highly unusual quantum ...
Phys.org / Shell too snug? Hermit crabs have a fix
For decades, biologists have known that hermit crabs forced to live in shells that are too small slow their growth. What wasn't clear was how they did it. New research suggests the answer isn't simply that the crabs eat less. ...
Phys.org / Mating reveals cholesterol's hidden role in male fruit fly lifespan
Scientists have discovered that the optimal diet for male fruit flies may depend strongly on whether they are reproducing, challenging long-standing assumptions about nutrition and aging. Led by researchers from the University ...
Phys.org / Trace additive unlocks faster bioplastic biodegradation without losing transparency or strength
Compostable plastics could be part of a solution to the world's plastic waste problem. But currently these materials need industrial composting facilities to break down. In a step toward making a home-compostable plastic, ...
Phys.org / Rice gene switch helps plants rebound from cold and use nitrogen more efficiently
Global climate change has increased the frequency of regional cold spells, causing substantial yield losses and even crop failure. Meanwhile, excessive nitrogen fertilizer use in agriculture has increased non-point-source ...
