How much do our genes determine about our lives, and could they influence traits like risk-taking, antisocial behaviour or even violence? Ian Sample talks to Kathryn Paige Harden, a behavioural geneticist and professor of psychology at the University of Texas at Austin who studie

Researchers at McMaster University have discovered what they describe as a "megacluster" of genes in Streptomyces bacteria that produces four antibiotics that work together to stop rival bacteria.

Researchers at the University of California San Diego have developed a large-scale screening approach that identifies proteins controlling a fundamental step in gene expression known as alternative polyadenylation (APA). APA determines where an RNA molecule is cut and finished be

RNA interference is a natural mechanism for living cells to control whether specific genes are being used. Crowned with the 2006 Nobel Prize in Physiology or Medicine, the discovery of RNA interference has since been harnessed by scientists to create a powerful and growing class

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this process fails or if key genes are mutated.

In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating RNA into proteins—worked so closely in tandem that they were effectively attach

Nanoparticles are widely used in medicine to deliver drugs, genes or imaging agents to specific parts of the body. Once a nanoparticle reaches a cell, however, many things can happen—it can reach its target, be degraded, interact with proteins that help transport it, or interact

Researchers have demonstrated for the first time that the microalga Chlamydomonas reinhardtii alters the activity of about one-third of its protein-coding genes in response even to moderate temperature changes. The study, published in the journal The Plant Cell, points to far-rea

A research team led by Professor Chaogu Zheng from the School of Biological Sciences at the University of Hong Kong (HKU), in collaboration with scientists from Princeton University and Columbia University, has discovered how sensory-motor circuits—nerve circuits that turn sensor

Inside the cell nucleus, genes must be turned on and off with precision to regulate biological processes. The first models of gene regulation were developed in the 1960s, yet modern science continues to uncover new layers of control. A new study involving researchers from the Ins

Plants do not wait hours to respond to intense sunlight—they react within minutes. Researchers at Bielefeld University and the Australian National University have discovered a new signaling pathway that enables plants to directly adjust their protein production before genes in th
