A chip-scale device that both produces and detects a specialized gas used in biomedical analysis and medical imaging has been built and demonstrated at the National Institute of Standards and Technology (NIST). Described in Nature Communications, the new microfluidic chip produces polarized (or magnetized) xenon gas and then detect seven the faintest magnetic signals from the gas.

Music can be soothing or stirring, it can make us dance or make us sad. Blood pressure, heartbeat, respiration and even body temperature – music affects the body in a variety of ways. It triggers especially powerful physical reactions in pregnant women. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig have discovered that pregnant women compared to their non-pregnant counterparts rate music as more intensely pleasant and unpleasant, associated with greater changes in blood pressure. Music appears to have an especially strong influence on pregnant women, a fact that may relate to a prenatal conditioning of the fetus to music.

Women with diabetes before pregnancy (pre-gestational diabetes) are less likely than non-diabetic women to initiate breast-feeding of their babies. Meanwhile, women who develop diabetes during pregnancy (gestational diabetes) are less likely to continue breast-feeding having initiated it than non-diabetic women. These are the main findings of an article in the journal Public Health Nutrition from a research team in Nationwide Children’s Hospital, Ohio State University and West Virginia University.

New University of Otago research out of the world-renowned Dunedin Multidisciplinary Study does not support claims that fluoridating water adversely affects children’s mental development and adult IQ. The researchers were testing the contentious claim that exposure to levels of fluoride used in community water fluoridation is toxic to the developing brain and can cause IQ deficits. Their findings are newly published in the highly respected American Journal of Public Health.

Researchers have shown for the first time in an animal that is more closely related to humans that it is possible to make new bone from stem-cell-like induced pluripotent stem cells (iPSCs) made from an individual animal's own skin cells. The study in monkeys reported in the Cell Press journal Cell Reports on May 15th also shows that there is some risk that those iPSCs could seed tumors, but that unfortunate outcome appears to be less likely than studies in immune-compromised mice would suggest.

In 2008, researchers at the Perelman School of Medicine at the University of Pennsylvania showed that mutations in two proteins associated with familial Alzheimer's disease (FAD) disrupt the flow of calcium ions within neurons. The two proteins interact with a calcium release channel in an intracellular compartment. Mutant forms of these proteins that cause FAD, but not the normal proteins, result in exaggerated calcium signaling in the cell.
