Scientists are learning more about this leading complication of childbirth. Treatments are improving and doctors can test for biological markers that flag heightened risk.
In polar bears, dolphins, baboons and more, molecular signatures of aging are changing how conservationists assess population health, resilience and risk
Researchers are exploring why some individuals are naturally super-lean and may struggle to gain weight. The causes of such constitutional thinness offer clues to the physiology of weight control.
Public health researchers explain the levers that can reduce — or worsen — this global blight. A bright spot: There are more data than ever on strategies that can help.
Infusion of the tiny, sausage-shaped structures helps to rejuvenate tissues deprived of blood. Researchers hope the technique can treat a variety of damaged organs.
Our genomes are peppered with DNA segments called retrotransposons that can move from place to place. When unleashed, some can kill nerves and promote inflammation — a discovery that may inspire treatments for neurodegeneration.
Carshares, bikeshares and the like are a positive for the environment, though access to them isn’t equal. What can be done to give everyone more transportation options?
How dangerous is it? Where did it come from? H5N1 influenza’s origins stretch back to the 1990s, and key events paved the way for the outbreak we’re seeing today.
In people not adapted to life at altitude, the sparse oxygen can impair fetal growth, causing problems that can last a lifetime. Researchers are searching for remedies.
In metros like Reno, Nevada, citizen scientists hit the road to collect detailed temperature data — key to taming urban heat, saving lives and designing for a warmer future
Can genetically modified animals help ease the shortage of organs? After years of research into xenotransplantation, the field is at a turning point — yet risks and ethical issues remain.
