Entropy measurements reveal exotic effect in ‘magic-angle’ graphene

Most #materials go from being solids to liquids when they are heated. One rare counter-example is helium-3, which can solidify upon heating. This counterintuitive and exotic effect, known as the Pomeranchuk effect, may now have found its electronic analog in a #material known as magic-angle graphene, says a team of researchers from the Weizmann Institute…

Promising Results for Focused Ultrasound Treatment of Alzheimer’s

West Virginia University scientists used MRI scans to show what happens when ultrasound waves target a specific area of Alzheimer’s patient’s brains. They concluded that this treatment may induce an immunological healing response, a potential breakthrough for a disease that accounts for up to 80% of all dementia cases. Rashi Mehta, a researcher with the…

Exposure to Metals Can Impact Pregnancy

Exposure to metals such as nickel, arsenic, cobalt and lead may disrupt a woman’s hormones during pregnancy, according to a Rutgers study. The study appears in the journal Environment International. Exposure to metals has been associated with problems at birth such as preterm birth and low birth weight in babies, and preeclampsia in women. However, little…

Spotting Liars Is Hard, but Our New Method Is Effective and Ethical

Most people lie occasionally. The lies are often trivial and essentially inconsequential – such as pretending to like a tasteless gift. But in other contexts, deception is more serious and can have harmful effects on criminal justice. From a societal perspective, such lying is better detected than ignored and tolerated. Unfortunately, it is difficult to…

Mothers’ Stress May Lead to Preterm Births, Faster Aging in Children

Why do some people age faster than others? One potential answer, a new UCLA-led study indicates, is that a mother’s stress prior to giving birth may accelerate her child’s biological aging. The researchers found evidence that maternal stress adversely affects the length of a baby’s telomeres — the small pieces of DNA at the ends…
