Studies Find Stress Reprograms Cells

Modern twin studies have shown how cells adapt to stressors — like water loss — by reprogramming their internal signaling networks. The studies describe mechanisms that cells use to send signals between cellular machinery and avoid cell death. The drugs that enhance the adaptation mechanisms could help cells ward off multiple diseases, including type 2 diabetes, studies published in Cell Reports and Molecular Cell suggests.

A Tiny Cellular Machine that Massacre Viruses

Bass, Shen and their colleagues examined one such specialized machine, a protein from the common fruit fly, Drosophila melanogaster. Now that scientists know how the fly protein works, they may be able to use some of the same tricks to overcome viruses that cause human disease. The study findings were published in the journal Science 

Selenium protects specialized neurons from cell death

About 200 years ago, the Swedish scientist Jöns Jacob Berzelius discovered the trace element selenium, which he named after the goddess of the moon, Selene. Besides its industrial applications (chemical industry, production of semiconductors and toners), selenium is an essential trace element and indispensable for humans, many animals, and some bacteria. A team led by Dr. Marcus Conrad, research group leader at the Institute of Developmental Genetics (IDG), showed for the first time why selenium is a limiting factor for mammals.

High rate of mortality from sepsis in ICUs

Brazil has an extremely high rate of mortality from sepsis in intensive care units (ICUs), surpassing even mortality due to stroke and heart attack in ICUs. According to a survey conducted by researchers at the Federal University of Sao Paulo (UNIFESP) and the Latin American Sepsis Institute (LASI), over 230,000 adults die from sepsis in ICUs every year and about 55.7% of sepsis cases in ICUs end in death.
