New mechanism of avian flu transmission

International team of scientists reports discovery of a new mechanism of avian influenza virus circulation and transmission in nature, offering new insights into ecology, surveillance and prevention strategies of the viruses.

Mechanism for mate selection

Researchers have discovered a molecular switch that becomes activated in response to a potential mate's signal. Simply put, an organism knows that a potential mate is close-by and healthy enough to mate.

Mechanism behind Ritalin leaning boost

Doctors treat millions of children with Ritalin every year to improve their ability to focus on tasks, but scientists now report that Ritalin also directly enhances the speed of learning.

Tumor mechanism identified

A team of researchers have for the first time identified a key mechanism that makes certain cells become tumorous in the brain.

Key EBV mechanism discovered

A team of researchers identified the function of a protein which plays a critical role in the proliferation of the Epstein-Barr virus which can induce cancer.

Novel mechanism for gene regulation

Scientists have discovered that such micro RNAs also come into direct contact with genes, effectively turning off the genes in the process.

Biologists discover bacterial defence mechanism

Researchers discovered that bacteria possess an ingenious mechanism for preventing oxygen from harming the building blocks of the cell.

Mechanism for cell death after stroke

Scientists have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage.

Mechanism causes lupus-like symptoms in mice

Macrophages, the scavenger cells of the body's immune system, are responsible for disposing of dying cells. Researchers have identified one pathway in this important process in mice that, if disrupted, causes a lupus-like autoimmune disease.

Pharmacology: Ramoplanin reveals promising mechanism

Researchers have identified how a antibiotic known as Ramoplanin A2 can kill pathogenic bacteria by interrupting how they form their cell membranes.

Biotechnology: New DNA repair mechanism information

Researchers have shed new light on a process that fixes breaks in the genetic material of the body's cells and could lead to ways of enhancing chemotherapy drugs.

Biotechnology: Mechanism controlling neuronal migration

Understanding how neurons migrate to their proper place during brain development will offer insights into how malfunctions in the machinery cause epilepsy and mental retardation.

HIV-1's hijacking mechanism, biotechnology discovery

Researchers have pinpointed the key cellular machinery co-opted by HIV-1 to hijack the human cell for its own benefit.

Mechanism controls tumour growth in the brain

Scientists have discovered a molecular mechanism that plays a pivotal role in controlling cancer growth in the brain. The discovery could provide a basis for potentially effective therapies.

Mechanism that allows influenza invasion

Researchers at the University of Southern California have identified a critical molecular mechanism that allows the influenza virus to evade the body's immune response system.

Mechanism behind DNA repair

Scientists revealed results of experiments suggesting at least one way in which cascades of intracellular signals that repair DNA are regulated.

Novel virus entry mechanism discovered

Scientists working with Vaccinia virus, the smallpox vaccine, have discovered a novel mechanism that allows poxviruses to enter cells and cause infection.

RUB researchers clarify catalysis mechanism of cell growth protein Ras

Proteins accelerate certain chemical reactions in cells by several orders of magnitude. The molecular mechanism by which the Ras protein accelerates the cleavage of the molecule GTP and thus slows cell growth is described by biophysicists at the Ruhr-Universität Bochum led by Prof. Dr. Klaus Gerwert in the Online Early Edition of the journal PNAS.

Reversible oxygen-sensing ‘switching’ mechanism discovered

Bacteria that cause disease in humans have a ‘reversible switching mechanism’ that allows them to adapt to environments lacking oxygen, scientists at the University of East Anglia (UEA) have found.

RNAi and DsiRNA: pathway, mechanism and design

Since its discovery, scientists have co-opted the RNAi mechanism as an experimental tool for studying the effects of gene silencing both in vitro and in vivo. Jaime Sabel and Hans Packer report
