Aging vessels connecting the brain and the immune system play critical roles in both Alzheimer’s disease and the decline in cognitive ability that comes with time, new research reveals. By improving the function of the lymphatic vessels, scientists at the University of Virginia School of Medicine have dramatically enhanced aged mice’s ability to learn and

New research from the University of Virginia School of Medicine explains why obesity causes harmful inflammation that can lead to diabetes, clogged arteries and other health problems. Doctors may be able to use this knowledge to battle these chronic diseases and others driven by damaging inflammation. “All these diseases have a common denominator,” said researcher

Most people with spinal cord injury are paralyzed from the injury site down, even when the cord isn’t completely severed. Why don’t the spared portions of the spinal cord keep working? Researchers at Boston Children’s Hospital now provide insight into why these nerve pathways remain quiet. They also show that a small-molecule compound, given systemically,

New research has found the natural vibrations of cars make people sleepier, affecting concentration and alertness levels just 15 minutes after drivers get behind the wheel. With about 20 per cent of fatal road crashes involving driver fatigue, researchers from RMIT University in Melbourne, Australia, hope their findings can be used by manufacturers to improve

The effectiveness of antibiotics can be altered by combining them with each other, non-antibiotic drugs or even with food additives. Depending on the bacterial species, some combinations stop antibiotics from working to their full potential whilst others begin to defeat antibiotic resistance, report EMBL researchers and collaborators in Nature on July 4. In the first

More than 3 million years ago, our ancient human ancestors, including their toddler-aged children, were standing on two feet and walking upright, according to a new study published in Science Advances. “For the first time, we have an amazing window into what walking was like for a 2½-year-old, more than 3 million years ago,” says

An international team of scientists reports the oldest unambiguous hunting lesions documented in the history of humankind. The lesions were found on skeletons of two large-sized extinct fallow deer killed by Neandertals about 120,000 years ago around the shores of a small lake (Neumark-Nord 1) near present-day Halle in the eastern part of Germany. The

Many animals — including sea lions, red deer, and dogs — use vocalizations to judge one another’s size and physical formidability when in competition for mates or other resources. Now, researchers reporting in the journal iScience on June 28 have found that humans can use nonverbal vocal cues, including aggressive roars, in a similar way.

The public debate on endocrine disrupting chemicals (EDCs) — exogenous substances that have the same or similar effects as endogenous hormones — has been going on for some time. Chemicals such as bisphenol A or phthalates, the latter of which are used to soften plastics, may be connected to rising infertility rates among men and

Want to be a supercentenarian? The chances of reaching the ripe old age of 110 are within reach — if you survive the perilous 90s and make it to 105 when death rates level out, according to a study of extremely old Italians led by the University of California, Berkeley, and Sapienza University of Rome.
