RNA-Binding Protein Influences Key Mediator of Cellular Inflammation, Stress Responses

July 31, 2015 — RNA-binding proteins such as RC3H1 regulate the degradation of the mRNA molecules and thus prevent the production of specific proteins. Researchers have now shown that ROQUIN binds several thousand ... read more

Protein Machines Make Fluctuating Flows Unconsciously

July 31, 2015 — Protein machines, regardless of their specific functions, can collectively induce fluctuating hydrodynamic flows and substantially enhance the diffusive motions of particles in the cell, an ... read more

July 27, 2015 — Researchers have discovered a long-overlooked process important for converting a long, string-like DNA molecule into a chromosome. This finding gives us a better understanding of the mechanism of how ... read more

July 24, 2015 — Pathogenic bacteria develop killer machines that work very specifically and highly efficiently. Scientists have solved the molecular mechanism of a fish toxin that could be used in the future as a ... read more

July 22, 2015 — The structure of a simple but previously unexamined pump that controls the passage of proteins through a bacterial cell membrane has been discovered by researchers. This achievement that offers new ... read more

July 22, 2015 — Scientists have exploited the light of fireflies in a new method that detects biological molecules without the need for complex devices and high costs. The researchers were able to add a small ... read more

July 22, 2015 — Scientists have published an overall map of how the cells in the human body communicate by systematically analyzing the relationship between ligands and ... read more

First Synthesis of Molecules That Cause Rapid Cell Death in Cancer

July 21, 2015 — The first total syntheses of certain compounds involved in excessive cell death in leukemia has been carried out by researchers. The researchers completed the total syntheses of several members of ... read more

Yeast Cells Optimize Their Genomes in Response to the Environment

July 21, 2015 — Researchers have shown that yeast can modify their genomes to take advantage of an excess of calories in the environment and attain optimal ... read more

Sweet Revenge Against Superbugs

July 21, 2015 — A special type of synthetic sugar could be the latest weapon in the fight against superbugs. A team of scientists has discovered a potential new class of antibiotics inspired by sugar molecules ... read more

July 21, 2015 — The things we do to extend our lives -- quitting smoking, cutting back on carbs, taking up jogging -- all have some impact on our longevity, if only just a little. But no matter how hard we work ... read more

New Insights Into Biofilm Formation Could Lead to Better Therapies, but Mysteries Remain

July 20, 2015 — Biofilms are tough, opportunistic, highly antibiotic resistant bacterial coatings that form on catheters and on medical devices implanted within the body. Investigators have now shown that a ... read more

July 20, 2015 — Some bacteria and viruses take advantage of the way our immune system works to infect us. Researchers now describe some of the trickery used by ... read more

July 17, 2015 — A new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance has been described by researchers. The team developed a new glucose analogue ... read more

July 17, 2015 — A group of scientists proposes a quick alternative for predicting the internal dynamics of RNA molecules (how the different parts move in relation to each other). This simple solution, which uses ... read more

July 16, 2015 — In response to an infection, the immune system refines its defensive proteins, called antibodies, to better target an invader. New research has revealed two mechanisms that favor the selection of B ... read more

July 16, 2015 — According to new research, the defense hormone salicylic acid helps select which bacteria live both inside and on the surface of a plant's roots, keeping some bacteria out and actively ... read more

July 16, 2015 — Iron regulatory proteins play an important role in the body's immune system. Proteins responsible for controlling levels of iron in the body also play an important role in combating infection, ... read more

July 15, 2015 — A research team has reconstructed the crystal structure of BAP, a protein involved in the process by which marine archaea release carbon, to determine how it functioned, as well as its larger role in ... read more

Molecular Architecture of Cell Fission Processes Has Been Revealed

July 15, 2015 — Biological evolution has always gone hand in hand with cell evolution. The cells of eukaryotes, the most advanced branch in the evolutionary tree, are characterized by the fact that their nuclei are ... read more
