Animal study links mutation of CD38 gene to major neurochemical dysfunctions found in autism — ScienceDaily

Oxytocin has been the focus of intense research around autism spectrum disorder (ASD) due to the hormone’s reported positive effects on anxiety, empathy, social interaction, and maternal behavior. ASD is characterized by early onset of behavioral and cognitive alterations, and by low plasma levels of oxytocin. The enzyme CD38 was recently demonstrated to be critical…

Pediatric onset multiple sclerosis study examines baffling, often-overlooked disease — ScienceDaily

Seemingly overnight, healthy children develop mysterious, potentially disabling symptoms. When children finally receive a diagnosis, often after weeks of tests and office and hospital visits, the parents may be shocked to learn that they have multiple sclerosis — a potentially disabling autoimmune disease once believed to affect only adults. “For many years, the tagline for…

Surprise survival mechanism could lead to retooled drugs to treat infectious diseases — ScienceDaily

As bacteria continue to demonstrate powerful resilience to antibiotic treatments — posing a rising public health crisis involving a variety of infections — scientists continue to seek a better understanding of bacterial defenses against antibiotics in an effort to develop new treatments. Now, researchers at the University of California San Diego who combine experiments and…

Yo-yo dieting may increase women’s heart disease risk — ScienceDaily

Yo-yo dieting may make it harder for women to control a variety of heart disease risk factors, according to preliminary research presented at the American Heart Association’s Epidemiology and Prevention | Lifestyle and Cardiometabolic Health Scientific Sessions 2019, a premier global exchange of the latest advances in population-based cardiovascular science for researchers and clinicians. “Achieving…

A million functional microscopic robots produced from a 4-inch silicon wafer in new nanofabrication process — ScienceDaily

Researchers have harnessed the latest nanofabrication techniques to create bug-shaped robots that are wirelessly powered, able to walk, able to survive harsh environments and tiny enough to be injected through an ordinary hypodermic needle. “When I was a kid, I remember looking in a microscope, and seeing all this crazy stuff going on. Now we’re…

Germ-fighting catheter coating may help prevent infections — ScienceDaily

Brown University researchers have developed a new antibacterial coating for intravascular catheters that could one day help to prevent catheter-related bloodstream infections, the most common type of hospital-acquired infection. “These kinds of infections are a major burden for hospitals, health care providers and most of all for patients,” said Anita Shukla, an assistant professor of…

Early onset menstruation linked to high blood pressure in late adulthood, UGA study finds — ScienceDaily

The age a woman begins menstruation is associated with having high blood pressure later in her life, according to a team of researchers at the University of Georgia. Specifically, researchers found that early onset menstruation significantly increased risk of hypertension in late adulthood, even after controlling for independent social economic factors, lifestyle behaviors, and other…

Frilly surfaces that help slugs move may motivate future energy-efficient, soft-body robots, according to researchers — ScienceDaily

What do pizza slices, sea slugs and one possible design for future soft-bodied robots have in common? They all have frilly surfaces, and new insights about the surprising geometry of frilly surfaces may help a future generation of energy-efficient and extremely flexible soft-body robots move. The complex folds of a frilly surface like coral reefs…
