Study: Cells prevent DNA repair

The Genomic Instability Group led by researcher Óscar Fernández-Capetillo at the Spanish National Cancer Research Centre (CNIO), has for the first time obtained a panoramic photo of the proteins that take part in human ...

Bacteria appear to speed up their evolution by positioning specific genes along the route of expected traffic jams in DNA encoding. Certain genes are in prime collision paths for the moving molecular machineries ...

Double-strand breaks in DNA happen every time a cell divides and replicates. Depending on the type of cell, that can be pretty often. Many proteins are involved in everyday DNA repair, but if they are mutated, ...

New biological research reveals how an invading virus hijacks a cell's workings by imitating a signaling marker to defeat the body's defenses. By manipulating cell signals, the virus destroys a defensive protein designed ...

Cells in the human body are constantly being exposed to stress from environmental chemicals or errors in routine cellular processes. While stress can cause damage, it can also provide the stimulus for undoing the damage. ...

When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis.

An experiment with 30 metronomes reveals chimera states which combine aspects of synchrony and of disorder. Researchers had been looking for such states for ten years.

A wooden beam that has long been the focus of the search for a 17th century shipwreck in northern Lake Michigan was not attached to a buried vessel as searchers had suspected, but still may have come from the elusive Griffin ...

It is likely some of the most widespread and oldest art in the United States. Pieces of rock art dot the Appalachian Mountains, and research by University of Tennessee, Knoxville, anthropology professor Jan ...

People who are considered unattractive are more likely to be belittled and bullied in the workplace, according to a first-of-its-kind study led by a Michigan State University business scholar.

The alvarezsauroid theropod Linhenykus monodactylus from the Upper Cretaceous of Inner Mongolia, China is the first known monodactyl non−avian dinosaur, providing important information on the complex patterns ...

At the recent Harvard IT Summit, Anne Margulies, vice president and University chief information officer, mentioned how Harvard had been at the forefront of information technology since its inception, even to the point of ...
