Rewrite the textbooks: Transcription is bidirectional

Researchers in the groups of Lars Steinmetz at the European Molecular Biology Laboratory in Heidelberg, Germany, and Wolfgang Huber at the European Bioinformatics Institute iin Hinxton, UK, have now unraveled how yeast generates its transcripts and have come a step closer to understanding their function. The study, published online in Nature, redefines the concept of promoters (the start sites of transcription) contradicting the established notion that they support transcription in one direction only.

Dramatic expansion of dead zones in the oceans

Unchecked global warming would leave ocean dwellers gasping for breath. Dead zones are low-oxygen areas in the ocean where higher life forms such as fish, crabs and clams are not able to live. A team of Danish researchers have now shown that unchecked global warming would lead to a dramatic expansion of low-oxygen areas zones in the global ocean by a factor of 10 or more. The findings are published in the scientific journal Nature Geoscience.

Scientists unmask genetic markers associated with psoriasis

Scientists at the University of Michigan Department of Dermatology, the U-M School of Public Health and their collaborators have found DNA “hotspots” that may reveal how genetic differences among individuals result in psoriasis, an autoimmune disease of the skin. Published in Nature Genetics, the findings could lead to new drug targets and tailored treatments for the disease.
