Novel cell division mechanism discovered

A novel cell division mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth. The study is published today in the online version of the journal of the American National Academy of Sciences, PNAS.

Georgia Institute of Technology receives EPA safe drinking water research grant

The U.S. Environmental Protection Agency announced the award of a $600,000 research grant to Georgia Tech to improve the detection of known and emerging drinking water contaminants; including the harmful substances produced by blue-green algae in algal blooms and noroviruses.

U.S. spinach and lettuce to be irradiated to stop outbreaks of foodborne bacteria

Following an increasing number of outbreaks of foodborne illnesses over the last few years, the Food and Drug Administration (FDA) in the United States is about to allow food producers to irradiate spinach and iceberg lettuce to kill foodborne bacteria.

Bacterial vaginosis may increase risk of HIV infection

A common vaginal infection may make women more susceptible to contracting HIV, the virus that causes AIDS, University of North Carolina at Chapel Hill School of Public Health researchers have found.

Cranberry juice shows promise for urinary tract infections

For generations, people have consumed cranberry juice, convinced of its power to ward off urinary tract infections, though the exact mechanism of its action has not been well understood.

Scientists mimic molecules to protect against plague

Bacteria that cause pneumonic plague can evade our first-line defences, making it difficult for the body to fight infection. In fact, a signature of the plague is the lack of an inflammatory response. Now, scientists have discovered a way to protect against death following infection with plague bacteria, by using molecules that can mimic the pathogens. According to research published in the July issue of Microbiology, these molecules make antibiotics more effective and can even be used to protect against other diseases.

Researchers crack final part of the immune system code

A group of researchers at the Technical University of Denmark and the University of Copenhagen have developed models of neural networks that make it possible to simulate how the body protects itself from disease and predict the immune system's access codes.

Natural substance Argyrin shows promise for new cancer therapies

The effective treatment of many forms of cancer continues to pose a major problem for medicine. Many tumours fail to respond to standard forms of chemotherapy or become resistant to the medication.

Salmonella bacteria found in garden birds are sensitive to antibiotics

Scientists at the University of Liverpool have found that Salmonella bacteria found in garden birds are sensitive to antibiotics, suggesting that the infection is unlike the bacteria found in livestock and humans.

The emerging role of infection in Alzheimer’s

A number of chronic diseases are in fact caused by one or more infectious agents. For example, stomach ulcers are caused by Helicobacter pylori, chronic lung disease in newborns and chronic asthma in adults are both caused by Mycoplasmas and Chlamydia pneumonia, while some other pathogens have been associated with atherosclerosis. The realization that pathogens can produce slowly progressive chronic diseases has opened new lines of research into Alzheimer's disease.

Scientists reveal the genetic determinants of fat storage in cells

New research by the Gladstone Institutes of Cardiovascular Disease (GICD) and the University of California, San Francisco (UCSF), has revealed the genetic determinants of fat storage in cells, which may lead to a new understanding of and potential treatments for obesity, diabetes, and heart disease. While scientists have long understood that lipid droplets contribute to fat build up in cells, the genes involved in droplet biology have been a focus of extensive research.

Plant flavonoid luteolin reduces inflammatory response in the brain

Researchers at the University of Illinois report this week that a plant compound found in abundance in celery and green peppers can disrupt a key component of the inflammatory response in the brain. The findings have implications for research on aging and diseases such as Alzheimer's and multiple sclerosis.

Scientists publish guidelines for the improved description of genomes and metagenomes

The Genomic Standards Consortium (GSC), an international initiative including representatives from a range of major sequencing and bioinformatics centres, has created a new guideline for describing genomes and metagenomes. The guideline, 'Minimum Information about a Genome Sequence' (MIGS), is published in the May issue of the journal Nature Biotechnology.

Fruit fly avoidance mechanism could lead to new ways to control pain in humans

At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse. To survive, they must leave the fruit, wander off and burrow into the earth where they avoid food as if it were poison. Only then can the larvae grow and hatch into flies that will take wing to lay their own eggs.
