16+ hour, 34+ min ago   (726+ words) Researchers at Carnegie Mellon University's School of Computer Science, the University of Pittsburgh School of Medicine and the University of Washington have uncovered a previously underexplored feature of Alzheimer's disease that may help scientists identify new avenues for treatment. To…...

2+ day, 6+ hour ago   (651+ words) Long-lived bats appear to combine powerful immune defenses with unusual strategies for eliminating damaged cells, potentially helping them avoid cancer and disease for decades. Researchers hope these genetic tricks could eventually reveal new ways to protect human health during aging....

3+ day, 2+ hour ago   (837+ words) For roughly two centuries, human life expectancy climbed steadily as medicine, sanitation, nutrition, and healthcare improved. More recent research, however, suggests that this long upward trend may now be leveling off in developed countries. If that is the case, the…...

3+ day, 15+ hour ago   (483+ words) Tiny Ions Help DNA Overcome Repulsion Professor Agnes Noy, from the School of Physics, Engineering and Technology at the University of York, co-led the research. She said: "This discovery could help researchers identify regions of the genome specially involved in…...

5+ day, 6+ hour ago   (746+ words) Your morning coffee may be doing more than helping you wake up. Research from Queen Mary University of London suggests that caffeine can activate an ancient cellular energy system involved in growth, stress resistance, and DNA repair. Those processes are…...

5+ day, 16+ hour ago   (186+ words) More than 1,200 genetic variants have been linked to the Big Five personality traits, and many of the same variants are also associated with health, longevity, careers, income, and everyday habits. The findings reveal a surprisingly wide genetic connection between personality…...

6+ day, 5+ hour ago   (199+ words) A surprising immune system signal may help explain why zebrafish can regenerate damaged spinal cords so effectively. Researchers found that certain neutrophils release Il-4, which calms harmful inflammation and allows injured nerve fibers to grow again. Without these cells, healing stalled,…...

1+ week, 2+ day ago   (450+ words) All known life on Earth relies on the same four-letter genetic alphabet. Researchers at the University of California San Diego have now shown that one of biology's most important enzymes can accurately read and transcribe a much larger version containing…...

1+ week, 6+ day ago   (520+ words) Microglia are the brain's most abundant immune cells. They help protect the brain from harmful invaders, clear away damaged neurons, and support normal brain development. Researchers at Columbia's Zuckerman Institute have now found for the first time that human microglia,…...

2+ week, 1+ day ago   (984+ words) Dogs and humans may share some of the same biological patterns tied to lifespan, according to new research from the Dog Aging Project. The finding could give scientists a useful new way to investigate how aging works in both species....
