Prenatal stress passed across generations and disrupt masculinization of the developing mouse brain

in environment, medicine, biology, omics

A new study finds that experiences in the womb can lead to individual differences in stress response that may be passed across generations.  The study shows that sons of male mice exposed to prenatal stress are more sensitive to stress as adults and these mice may have smaller testes.

The study was published in the August 17 issue of The Journal of Neuroscience.

Hydrogen-powered symbiotic bacteria in deep-sea hydrothermal vent mussels

in technology, biology

During a recent expedition to hydrothermal vents in the deep sea, researchers from the Max Planck Institute of Marine Microbiology and the Cluster of Excellence MARUM discovered mussels that have their own on-board ‘fuel cells’, in the form of symbiotic bacteria that use hydrogen as an energy source.

Caffeine lowers risk of UV-induced skin cancer - new study

in medicine, biology

Like to drink a coffee in the morning?  How about taking a bath in light coffee? The results of a new study suggest that caffeine applied directly to the skin might help prevent damaging ultra violet (UV) light from causing skin cancer.

Human Brains Shrink With Age, But Not Chimpanzee's

in medicine, biology

Human brains shrink with aging. The extreme amount of brain shrinkage resulting from normal aging in humans seems to be unique. Brains shrink in humans, potentially causing a number of health problems and mental illnesses as people age, but do they shrink similarly in the chimpanzees, our closest relatives?

Dolphins’ “Remarkable” Recovery from Injury Might Provide Insights for the Care of Human Injuries

in medicine, biology

A dolphin’s ability to heal quickly from a shark bite with apparent indifference to pain, resistance to infection, hemorrhage protection, and near-restoration of normal body contour might provide insights for the care of human injuries, says Dr Michael Zasloff at the Georgetown University Medical Center.

Glucose meters to be used for food, water and blood chemistry- new study

in technology, environment, medicine, biology, omics

Glucose meters can do more than just measuring blood glucose.  A new invention published in Nature Chemistry claims that glucose meters can be used for the quantitative detection of a broad range of target molecules in blood, water or food.

Bioelectricity - Engineering Unexcitable Cells To Be Electrically Excitable

in medicine, biology

Duke University bioengineers have turned normally "unexcitable" cells into cells capable of generating and passing electrical current, or  bioelectricity.  This development has major implications in the treatment of health conditions such as heart attack.

Modern Human Ancestors Mated With Neanderthals - New Genetic Evidence

in biology, omics

There have been several past reports suggesting interbreeding between modern humans and the Neanderthals. A new study further confirms that Neanderthals and expanding African migrants mated prior to or very early on the way out of Africa leading to the successful colonization of the planet.
