Deep Sea Foraminifera Species Unveil Secrets of Life in Extreme Environments

Most life on Earth relies on the sun's energy for survival, but what about organisms in the deep sea that live beyond the reach of its rays? A new study led by Woods Hole Oceanographic Institution (WHOI), published in The ISME Journal, sheds light on how a species of foraminifera, single-celled organisms found in almost all marine habitats, thrives in a dark, oxygen-free environment.

Epigenetic Mechanism Controls Placental Blood Vessel Formation

If the development of blood vessels in the placenta is impaired, fetal growth retardation may result. Scientists from the German Cancer Research Center (DKFZ) and the Mannheim Medical Faculty of Heidelberg University discovered that the correct development of functioning blood vessels in the mouse placenta is controlled epigenetically: One of the enzymes that modify gene activity using methyl groups is responsible.
