2+ mon, 3+ week ago   (854+ words) Couples carrying a serious inherited disease can already avoid passing it on. But editing human embryos to repair the faulty gene itself has stayed out of reach. With IVF, doctors can screen a batch of embryos and transfer one that…...

2+ mon, 4+ week ago   (764+ words) Disturbed land tends to flatten life. Build a city over a forest, and what moves in grows more uniform, with fewer species block to block. Soil antibiotic resistance was expected to follow. That assumption just cracked. Soil samples from across…...

3+ mon, 2+ week ago   (912+ words) About 20 years ago, researchers discovered that some people carry a mutation that permanently switches off a single gene in the liver. Those individuals have low cholesterol for life and far fewer heart attacks – not because of anything they do, but…...

5+ mon, 3+ week ago   (973+ words) One of the most advanced cancer treatments available today may soon get a major upgrade. CAR-T therapy has already saved lives, but it remains complex, expensive, and difficult to access. Now, researchers at the University of California, San Francisco (UCSF)…...

6+ mon, 1+ week ago   (836+ words) Ty Sperle, a 19-year-old from Kelowna, British Columbia, has become the first person cured of a rare inherited immune disorder after doctors used prime gene editing to correct a single DNA error in his own blood-forming cells. His recovery shows…...

6+ mon, 3+ week ago   (1100+ words) For decades, scientists have debated whether long life is mostly a matter of healthy habits or inherited biology. A new analysis suggests the balance may tilt more strongly toward genes than previously thought. By reexamining decades of twin records, researchers…...

6+ mon, 3+ week ago   (905+ words) For years, sleep was treated as a soft subject in biology – more psychology than hard neuroscience. But that view has flipped. Researchers now study sleep at the level of cells and metabolism, asking what it actually does inside the brain....

7+ mon, 1+ day ago   (964+ words) Drug-resistant infections are becoming harder to treat, but testing new medicines in animals is often slow and expensive. Scientists have now taken a major step forward by creating the first genetically modified wax moths – tiny larvae whose genes can be…...

7+ mon, 6+ day ago   (1011+ words) Burns have been part of human life for as long as we have lived with fire. Fire cooks our food, warms our homes, and powers much of the modern world. It has done so for more than a million years....
