Scientists reveal new insights into mechanism of gene regulation by 'magic spot'

Using an innovative crystallization technique for studying three-dimensional structures of gene transcription machinery, an international team of researchers, led by scientists at Penn State, has revealed new insights into the long debated action of the "magic spot"--a molecule that controls gene expression in Eschericahia coli and many other bacteria when the bacteria are stressed.

Researchers uncover new details about function of enigmatic protein

In a recent study, a research group at MedUni Vienna has published further details about the function of an enigmatic protein. The biological necessity of this protein, which can chemically alter certain building blocks of the genetic information, has been debated for quite a while.

Study reveals how dengue virus replicates without triggering the body's defenses

A new study reveals how dengue virus manages to reproduce itself in an infected person without triggering the body's normal defenses. Duke researchers report that dengue pulls off this hoax by co-opting a specialized structure within host cells for its own purposes, like a lazy roommate sneaking bits of his laundry into the communal wash.

Post-workout muscle-building response better in people eating whole eggs than egg whites

People who consume 18 grams of protein from whole eggs or from egg whites after engaging in resistance exercise differ dramatically in how their muscles build protein, a process called protein synthesis, during the post-workout period, researchers report in a new study.

Two studies show how cells adapt to stressors by reprogramming internal signaling networks

In a pair of publications, researchers have shown how cells adapt to stressors--like water loss--by reprogramming their internal signaling networks.

IU scientists discover way to make drug treatment more successful against malaria

Indiana University School of Medicine researchers have identified a way to block the ability of parasites that cause malaria to shield themselves against drug treatments in infected mice--a finding that could lead to the development of new approaches to combat this deadly disease in humans.

Researchers catch killer cells red-handed in the act of microbial murder

Immune cells called "killer cells" target bacteria invading the body's cells, but how do they do this so effectively? Bacteria can quickly evolve resistance against antibiotics, yet it seems they have not so readily been able to evade killer cells. This has caused researchers to become interested in finding out the exact mechanism that killer cells use to destroy bacterial invaders.

Research reveals novel mechanism of ribosome dimerization using cryo-electron microscopy

Antibiotics are the most common medication used to treat microbial infections. Many antibiotics target intracellular bacterial ribosomes - cellular factories that synthesize proteins - which are essential for bacterial survival and proliferation.

MIT engineers design more effective synthetic mRNA delivery system

By delivering strands of genetic material known as messenger RNA into cells, researchers can induce the cells to produce any protein encoded by the mRNA. This technique holds great potential for administering vaccines or treating diseases such as cancer, but achieving efficient delivery of mRNA has proven challenging.

Protein intake three times a day could be linked to greater mass, muscle strength in the elderly

Loss of muscle is an inevitable consequence of aging that can lead to frailty, falls or mobility problems. Eating enough protein is one way to remedy it, but it would seem that spreading protein equally among the three daily meals could be linked to greater mass and muscle strength in the elderly.

Biochemist explores complex interaction of activation and regulation in fat breakdown

What happens and where, when the body’s fat stores are activated? With the support of the Austrian Science Fund FWF, the biochemist Ruth Birner-Grünberger investigates the complex interaction of activation and regulation in fat breakdown, thus providing a basis for new therapeutic approaches for illnesses such as diabetes or arteriosclerosis.
