Researchers show how proteins form DNA-repair mechanism in living bacteria

Two recent research have shown a completely new perspective of how bacterial cells repair broken parts of their DNA (lesions).

Plant biologists determine molecular ‘blueprint’, showing how plants observe light

For survival, plants depend on their ability to detect light. Plants, unlike animals, do not have photoreceptors in their eyes to receive and transmit messages from visual inputs.

Researchers determine major protein complexes that cause ribosome production

Scientists at UT Southwestern have discovered a four-protein complex that seems to play a significant function in the formation of ribosomes, which serve as protein factories for cells, as well as a surprise role in neurodevelopmental diseases.

Exceptional research recordings display RNA switching “on” and “off”

RNA switches (also known as riboswitches) control which genes are turned “on” and “off”, much like a light switch. Although this appears to be a straightforward process, biologists have been astonished by the inner workings of these switches for decades.

Researchers discover abnormal gene mutations that lead to cancer development

The reason why the control centers, or nuclei, of certain blood cancer cells, have a peculiar structure is still a mystery.

Reintroduction of captive-bred animals offers potential solution to cope with biodiversity crisis

Biodiversity loss has accelerated over the last decade, driven by the impact of global warming, alteration of habitats and the dispersal of invasive exotic species due to human action.

Study reveals genetically driven mucus pathobiology in asthma

A significant amount of genetic risk for asthma is likely mediated through altered gene expression within the airway epithelium.

New long-lived biological computers could potentially persist inside cells

Tiny biological computers made of DNA could revolutionize the way we diagnose and treat a slew of diseases, once the technology is fully fleshed out.

Researchers analyze a powerful tool to enhance drug discovery

Hormones or chemical messengers link to cell membrane receptors to tweak how the cell responds, creating a metaphorical interaction and traffic network on the surface of cell membranes inside human body.

Ancestors of many animal species may have inhabited a deltaic environment

The ancestors of many animal species alive today may have lived in a delta in what is now China, new research suggests.

Study shows how genes help control appetite and obesity in children

Have you ever noticed why little newborns gain weight at varying rates and in varying amounts during their early years of life?

Cryo-electron microscopes help determine how “911” molecule repairs DNA damage

When something unexpected happens with DNA replication, cells call their own form of 911 to stop the process and rectify the problem.

Research reveals how a marine bacterium makes a potent anti-cancer molecule

Years of toil in the laboratory have revealed how a marine bacterium makes a potent anti-cancer molecule.

Yale and uOttawa researchers partner to solve a puzzle rooted in the deepest past of evolution

For decades, scientists have been trying to unravel an enduring mystery of structural biology: Why do two otherwise identical protein forms found in everything from plants, amphibians and human beings hang onto a slight variation across the mighty span of evolution?
