Researchers at the University of Delaware have discovered that when the leaf of a plant is under attack by a pathogen, it can send out an S.O.S. to the roots for help, and the roots will respond by…

The DNA's double helix--the sub-microscopic core of our life--has been the subject of intense study and scrutiny for decades. Observations and measurements at the scale of DNA are tricky. The…

Scientists from the Universities of Bath and Exeter have developed a rapid new way of checking for toxic genes in disease-causing bacteria which infect insects and humans. Their findings could in the…

Proteins found in sperm are central to understanding male infertility and could be used to determine new diagnostic methods and fertility treatments according to a paper published by the journal…

A gene contained in laboratory yeast has helped an international team of researchers uncover new findings about the process by which protein molecules bind to control sequences in genes in order to…

Obesity is a health problem in western countries in part from an increase in the mass and number of white fat cells. Because white fat cells are post-mitotic, meaning that they cannot divide,…

Bacteria are everywhere and can survive in almost anything. Finding out exactly how bacteria respond and adapt to stresses and dangers will further our understanding of the basic survival mechanisms…

Small stretches of DNA with unknown utility harbor a big secret, say researchers at the Stanford University School of Medicine, but they don't know what it is. Those secrets are always the biggest.…

A team of scientists has identified a gene in rice that controls the size and weight of rice grains. The gene may prove to be useful for breeding high-yield rice and, thus, may benefit the vast…

Who wouldn't want a map of all the known yeast metabolic pathways on the wall? Download your copy here (PDF). The catch is you have to print it out yourself. This poster offers a birds-eye glance at…
