Scientists found 45 chemicals in pregnant women and many were linked to birth risks
One of the largest investigations ever conducted into chemical exposure during pregnancy has found that pregnant women regularly encounter dozens of chemicals found in everyday life. Researchers say many of these substances may influence how early a baby is born and how much the baby weighs at birth, both of which can affect health well beyond infancy.
Scientists find the “Achilles’ heel” of deadly gut bacteria
Enterotoxigenic E. coli and Shigella are responsible for hundreds of millions of infections worldwide each year and remain among the leading causes of fatal diarrheal disease, particularly in children. Despite decades of research, scientists have not yet developed effective vaccines against either pathogen. One major challenge is that the bacterial features typically targeted by vaccines vary widely between strains.
Scientists may have finally found how Alzheimer's kills brain cells
Scientists have identified evidence of a previously unknown process that may explain how brain cells die in Alzheimer's disease and frontotemporal dementia (FTD). The discovery, centered on a mechanism known as karyoptosis, could point researchers toward new ways to slow the progression of these devastating conditions.
Scientists discover a protein switch that burns fat and blocks new fat cells
Modern weight loss medications have transformed obesity treatment, helping many people lose significant amounts of weight. But these drugs often come with an important drawback: They can also reduce muscle mass. Now, researchers have uncovered a biological mechanism that may one day help address that challenge while also boosting the body's ability to burn fat.
This spray-on powder can stop life-threatening bleeding in 1 second
Excessive blood loss is the leading cause of death from combat injuries, making rapid bleeding control one of the biggest challenges in battlefield medicine. Researchers at KAIST, including an Army Major, have developed a next generation spray-on powder that can stop severe bleeding in about one second. The innovation could significantly improve survival for wounded soldiers while also offering broad potential for civilian emergency care.
