Phys.org / Desert field test with NASA advanced rover prototype
A prototype four-wheel rover developed at NASA's Jet Propulsion Laboratory with advanced mobility and robotic autonomy capabilities trundled across the Colorado Desert near Plaster City, California, during a field test in ...
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 / 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 ...
Medical Xpress / Sunscreen misinformation attracts high engagement on TikTok, study finds
Sunscreen is overwhelmingly promoted in popular TikTok videos, but content containing health misinformation about sunscreen attracts disproportionately high audience engagement, according to a new study published June 18 ...
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 / 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 / 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 / Ancient DNA uncovers deadly plague outbreak among Siberian hunter-gatherers 5,500 years ago
Plague is commonly associated with rats, crowded medieval cities, and the epidemics that swept across Europe during and after the Middle Ages. But a new study published in Nature shows that the disease was already lethal ...
Tech Xplore / NASA tests advanced capabilities for moon and Mars rovers
A prototype rover built with a new design for tackling rugged terrain is helping teams refine capabilities that could one day be used on future lunar and Red Planet missions.
Phys.org / Heat waves increase wildfire risk—a new study explains how much, and it's not a small number
When heat waves hit the Western United States, the risk of wildfires quickly rises. The prolonged heat dries out vegetation, but that's only part of the cause—heat waves also play other roles in spreading wildfires.
Phys.org / Super El Niños may lose their punch in a warming world
In a strong El Niño winter, normally dry regions can suddenly drown in rain. NASA notes that "typically dry regions can experience nearly two times as much rain during a strong El Niño." Indeed, the blockbuster El Niños of ...
Phys.org / Small forest fragments can protect more birds when the surrounding landscape is more helpful
Larger areas contain more species. This is one of the most ironclad laws of ecology, which explains why large natural areas usually receive higher priority in conservation strategies. In fragmented landscapes, this logic ...
