Tiny samples from asteroid Bennu are rewriting scientists' understanding of how our Solar System formed. New evidence suggests that Bennu was born where material from the inner and outer Solar System mixed, with Jupiter playing a surprising role in shaping its formation.
Scientists have proposed a way to detect “mirror life,” a hypothetical form of life that could pose serious risks to humans, animals, and ecosystems if artificially created. Using special fluorescent molecules and a type of polarized light also used in 3D movie technology, researchers believe they could distinguish ordinary organisms from their mirror-image counterparts.
The Sun’s seemingly peaceful regions are hiding a surprisingly complex magnetic world. Using a balloon-borne telescope high above Earth, scientists discovered delicate, thread-like magnetic structures woven through the solar atmosphere, apparently shaped by twisting motions on the Sun’s surface. They also mapped magnetic fields inside towering jets of solar material, revealing how those fields change with height.
Tiny snakes in Southeast Asia have mastered an extraordinary escape technique: rolling across the ground at speeds up to four times faster than ordinary slithering. Scientists discovered that dwarf reedsnakes accomplish this feat through precisely coordinated body movements that allow their bodies to rotate while their heads remain remarkably stable.
A major study has uncovered hidden warning signs of inflammatory bowel disease in the blood up to 10 years before diagnosis. Researchers discovered distinct antibody patterns that could help predict who would later develop Crohn’s disease or ulcerative colitis, even distinguishing people at risk of more complicated disease.
Scientists have discovered that switching off a protein called Mitch makes human cells burn more fat and prevents new fat cells from developing. The breakthrough builds on experiments in mice that showed remarkable resistance to obesity and improved muscular endurance, raising hopes for a new approach to weight-loss treatment.
Punching a virtual response box or swinging a virtual lightsaber can dramatically improve learning on certain tasks, according to new research from Florida Atlantic University's College of Engineering and Computer Science, which challenges long-standing assumptions about how people learn.
The Malik Lab thrives on competition. But for HHMI investigator Harmit Malik and his team at the Fred Hutchinson Cancer Center, it's the genomes—not the people—that are in conflict. The lab studies rapid evolution—the genetic changes that happen in a species over a few generations rather than thousands of years. These fast changes are often fueled by genetic conflicts—competitions between different entities trying to maximize their success at the expense of another.
A 150-million-year-old fossil discovered in China reveals a bizarre early bird with sharp teeth, a dinosaur-like claw, and a body built for life on the ground rather than flight. Scientists believe it represents the earliest known example of flight loss in birds, overturning assumptions about how these animals evolved.
Pollution from human-generated waste in marine ecosystems has reached critical levels, with cigarette butts (CBs) among the most persistent and harmful pollutants. Globally, an estimated 4.5 trillion cigarette butts are discarded annually, making them the most common type of litter on beaches over the past three decades.
