Biologists report on the long-term effects of heat stress on cells

A process of cell senescence is set in the early S-phase, when a topoisomerase-I collides a replication fork and a double-strand break appears. Credit: Sergey Razin (NAR paper) Heat shock (or stress) is a well-known factor of cell stress, though its delayed effects remain largely unknown. According to two articles by Russian scientists —a 2015 […]

Freezing plants to predict the fate of the Arctic

Freezing plants to predict the fate of the Arctic

Working in the depths of the polar night can have its challenges, but it can be breathtakingly beautiful, too. Credit: ystein Varpe, UNIS Global warming means much warmer winters in the Arctic, with more rain and icing. Researchers are working to understand what that will do to plants that have evolved to overwinter under a […]

Fahr African straw-coloured fruit bats fulfil important ecosystem functions by dispersing seeds and pollen during their flights. Researchers from the Max Planck Institute for Ornithology in Radolfzell together with colleagues from Ghana fitted African straw-coloured fruit bats (Eidolon helvum) […]

MSU part of team working to save endangered species in Nicaragua

The Baird’s tapir is one of several Central American animals that could be threatened by a canal project now under consideration in Nicaragua. An MSU researcher is a member of a team that has developed a conservation plan that might help save the habitat of this and other species. This photo was taken several years […]

Researchers at University of California, San Diego School of Medicine and Ludwig Cancer Research used the tiny roundworm C. elegans as […]

Bacterial airborne signal encourages fungal growth critical in lung infections

Bacterial airborne signal encourages fungal growth critical in lung infections

Researchers in France have discovered that volatile compounds released by a bacterial pathogen stimulate the growth of a fungal pathogen found in lung infections in cystic fibrosis (CF). The findings, published this week in mBio, an online open-access journal of the American Society for Microbiology, show for the first time that one pathogen can emit […]
