Stress during pregnancy may affect baby’s sex, risk of preterm birth — ScienceDaily

It’s becoming well established that maternal stress during pregnancy can affect fetal and child development as well as birth outcomes, and a new study from researchers at Columbia University Vagelos College of Physicians and Surgeons and NewYork-Presbyterian now identifies the types of physical and psychological stress that may matter most. The study was published online…

Modified multi-layered bismuth superconductor for higher critical temperatures — ScienceDaily

Scientists from Tokyo Metropolitan University have created a new layered superconducting material with a conducting layer made of bismuth, silver, tin, sulfur and selenium. The conducting layer features four distinct sublayers; by introducing more elements, they were able to achieve unparalleled customizability and a higher “critical temperature” below which superconductivity is observed, a key objective…

Drug reverses signs of liver disease in people living with HIV — ScienceDaily

Researchers at the National Institutes of Health and their colleagues at Massachusetts General Hospital (MGH) in Boston report that the injectable hormone tesamorelin reduces liver fat and prevents liver fibrosis (scarring) in people living with HIV. The study was conducted by the National Institute of Allergy and Infectious Diseases (NIAID) and the National Cancer Institute,…

Hydrologic simulation models that inform policy decisions are difficult to interpret — ScienceDaily

Hydrologic models that simulate and predict water flow are used to estimate how natural systems respond to different scenarios such as changes in climate, land use, and soil management. The output from these models can inform policy and regulatory decisions regarding water and land management practices. Numerical models have become increasingly easy to employ with…

Sweat monitors predict behavioral issues in teens severely affected with autism — ScienceDaily

When people become stressed, their bodies can respond by sweating. Now, researchers at the University of Missouri are monitoring how much adolescents severely affected by autism sweat in order to better understand when behavioral issues, such as aggression, are likely to occur. Bradley Ferguson analyzed the stress levels of eight adolescents who are severely affected…
