Scientists have created the first global map of how genetics and geography shape everything from aging to gut health. The groundbreaking study could transform how doctors treat patients from different backgrounds.
A Harvard study analyzing 10,000 years of human DNA reveals that red hair isn't a genetic fluke. Nature has been actively selecting for it, especially since humans started farming.
A groundbreaking genetics study reveals that redheads aren't just rare—they're evolutionary winners whose genes were actively favored for over 10,000 years. Scientists analyzed DNA from nearly 16,000 ancient remains and discovered hundreds of traits still evolving in humans, proving we're far from done changing.
The largest study of ancient human DNA reveals that human evolution has dramatically accelerated since farming began, reshaping everything from disease resistance to physical appearance. Scientists found nearly 500 gene variants that changed through natural selection as our ancestors adapted to revolutionary lifestyle changes.
Australian researchers are solving the puzzle of how humans might have babies in space, discovering surprising challenges that need solutions before we can settle other worlds. Their groundbreaking experiments reveal both obstacles and paths forward for space-faring families.
A Duke scientist's new book reveals how our bodies constantly adjust to different environments, from deep-sea diving to high altitudes. Understanding this shared human adaptability could fight dangerous health misinformation.
The U.S. government just launched major initiatives to phase out animal testing in drug development, backing new methods that better simulate human biology. The FDA released new guidance while the NIH committed over $150 million to institutions pioneering alternatives.
Researchers finally solved a mystery millions of years in the making: why humans evolved to be awake during the day while most early mammals were nocturnal. The answer lies in tiny cellular switches that respond differently to daily temperature changes.
Physicists at NYU built a handheld device using foam beads and sound waves that breaks Newton's Third Law and could unlock secrets of quantum computing and human biology. The exotic time crystal fits in your palm and uses technology as simple as packing peanuts floating on acoustic waves.
Scientists created a 3D chip that mimics human tumors so accurately it could replace animal testing in cancer research. The breakthrough means faster, more precise treatments tailored for actual human biology.
