New understanding of anti-malarial drug resistance

Researchers at Georgetown University Medical Center say they are moving closer to understanding why the most lethal form of human malaria has become resistant to drug treatment in the past three decades.

Treatment for enterotoxin B exposure

A research team led by the University of Illinois has developed a treatment for exposure to enterotoxin B, a noxious substance produced by the Staphylococcus aureus bacterium.

Latent memory of cells comes to life

New Danish research has examined the mechanisms behind latent cell memory, which can come to life and cause previously non-existent capacities suddenly to appear.

Health effects of polyphenols

Polyphenols, dietary substances from vegetables, fruits and green tea, bring about a change in the energy metabolism.

New understanding of ubiquitylation

It turns out there's more than one way to skin a gene. New research from Rockefeller University suggests that two closely related DNA unpackaging mechanisms may not work the way scientists thought.

New understanding of infectious prion

Researchers have known for decades that certain neurodegenerative diseases, such as mad cow disease or its human equivalent, Cruetzfeldt-Jakob disease, result from a kind of infectious protein called a prion.

Alzheimer's disease, Parkinson's disease, type 2 diabetes similar at the molecular level

Alzheimer's disease, Parkinson's disease, type 2 diabetes, the human version of mad cow disease (Creutzfeldt-Jakob disease), and other degenerative diseases are more closely related at the molecular level than many scientists realized, an international team of researchers, including an ESRF researcher, report in the journal Nature.

New compounds promising candidates for neurodegenerative disease drug development

Scientists have developed a novel strategy for tackling neurodegenerative diseases such as Huntington's disease: encouraging an individual's own cells to "eat" the malformed proteins that lead to the disease.

New vitamin extends lifespan in yeast cells

Imagine taking a vitamin for longevity! Not yet, but a Dartmouth discovery that a cousin of niacin prolongs lifespan in yeast brings the tantalizing possibility a step closer.

Scientists discover molecular mechanism that keeps HSV-1 activation restricted to a single gene for months or even years

By adulthood, most people have suffered at least one bout of painful cold sores brought on by the Herpes simplex virus 1, also known as HSV-1.

To live longer - eat less!

Scientists have known for a long time that animals fed diets which border on starvation live longer, but they are now saying that a particular gene is linked to calorie restriction.

Methods for marking molecules to identify gene alterations and metabolic shifts

Physical alterations of DNA in chromosomes can cause serious diseases such as Down syndrome, Prader-Willi syndrome, or cancer.

Important step towards a spatially and temporally quantifiable model of the cell

Cell membranes are like two-dimensional fluids whose molecules are distributed evenly through lateral diffusion.

New device to test for proteins that play important role in human health and disease

A new technology developed at the University of Toronto is revealing biochemical processes responsible for diseases such as cystic fibrosis and could one day pave the way for pharmaceutical applications.

Scientists discover key player in embryonic muscle development

Muscle fibers are large cells that contain many nuclei. They begin, like all animal cells, as naive embryonic cells. These cells differentiate, producing intermediate cells called myoblasts that are now destined to become muscle.

Analysis of Rhesus monkey genome provides new clues to primate biology

An international consortium of researchers has published the genome sequence of the rhesus macaque monkey and aligned it with the chimpanzee and human genomes.

First measurement of a cellular heartbeat

Researchers have made a breakthrough by detecting the electrical equivalent of a living cell's last gasp. The work takes them a step closer to both seeing the 'heartbeat' of a living cell and a new way to test drugs.

Researchers discover how cells fine-tune oxygen use

Researchers at Johns Hopkins have discovered how cells fine-tune their oxygen use to make do with whatever amount is available at the moment.

No apparent increase in coronary heart disease for women who initiate hormone therapy

Wyeth Pharmaceuticals, a division of Wyeth ( NYSE:WYE ) , provides comment on a re- analysis of pooled data from both hormone therapy arms of the Women's Health Initiative (WHI) Study published today in the Journal of the American Medical Association.

Penn State scientists reveal structure of gateways to gene control

Scientists at Penn State University will reveal in the 29 March 2007 issue of the journal Nature the first complete high-resolution map of important structures that control how genes are packaged and regulated throughout an entire genome.
