This common amino acid helped mice survive deadly inflammation
A minor injury, a serious infection, or even the flu can send the body down very different paths. Some people recover quickly, while others become severely ill or die. Scientists…
Your kitchen sponge is releasing microplastics every time you wash dishes
Kitchen sponges are a staple in most homes, but they may also be an overlooked source of microplastic pollution. A new study led by researchers at the University of Bonn…
Why cancer spreads more in middle age than in old age
Cancer becomes more common with age and is often harder to treat in older adults. Yet most cancer studies in mice do not reflect that reality. Fewer than 10% of…
Scientists found the hidden switch fueling alzheimer’s brain inflammation
The brain has its own built in immune defenses that help detect threats and protect nerve cells. But growing evidence suggests that in Alzheimer’s disease, these immune cells become stuck…
Intermittent fasting triggers surprising changes in the brain
More than one billion people worldwide now live with obesity, a condition that raises the risk of cardiovascular disease, diabetes, and several types of cancer. Yet losing weight and keeping…
Repairing DNA damage: Scientists discover a surprising new benefit of melatonin
Melatonin supplements may help the body repair DNA damage linked to night shift work, according to a small clinical trial published in Occupational & Environmental Medicine. The findings point to…
New 3D silicon chip breakthrough could extend Moore’s Law for years
For decades, the computing industry has followed a simple formula: make transistors smaller and pack more of them onto a chip. That strategy fueled the extraordinary rise in computing power…
Astronomers finally solve Saturn’s decades-long spin mystery
For years, Saturn appeared to be doing something impossible. Measurements suggested the giant planet’s rotation rate was changing over time, as if Saturn were somehow speeding up or slowing down.…
Protein traffic jams may explain aging, memory loss, and Alzheimer’s
Scientists at Stanford University have uncovered a major clue to why the brain deteriorates with age. Their research points to breakdowns in the cell’s protein production system, a process that…
Human organoids reveal how to reverse “irreversible” nerve damage
Scientists at the University of Cambridge have created tiny lab-grown brain and spinal cord systems that mimic how movement signals travel through the human nervous system. Using this model, the…
