Some bacteria steal iron from their human hosts - discovery could lead to new ways to fight tuberculosis

Like their human hosts, bacteria need iron to survive and they must obtain that iron from the environment. While humans obtain iron primarily through the food they eat, bacteria have evolved complex and diverse mechanisms to allow them access to iron.

FDA clears test that determines what type of cancer cells are present in a malignant tumor

The U.S. Food and Drug Administration has cleared for marketing a test that can help health care professionals determine what type of cancer cells are present in a malignant tumor.

Mechanism for postpartum depression found in the brains of mice

Researchers have pinpointed a mechanism in the brains of mice that could explain why some human mothers become depressed following childbirth. The discovery could lead to improved treatment for postpartum depression.

New oral vaccine combats various versions of the plague

A University of Central Florida researcher may have found a defense against the Black Plague, a disease that wiped out a third of Europe's population in the Middle Ages and which government agencies perceive as a terrorist threat today.

Eroded telomeres are behind dyskeratosis congentia aging syndrome

Each time a cell divides, the protective caps at the ends of chromosomes shorten - and when these caps are gone, so are we. Now, by using an unconventional strategy to shorten telomeres in mice, researchers at Rockefeller University have not only created the first faithful mouse model for studying a rare yet fatal premature aging syndrome, but they have revealed the molecular defect behind the disease.

microRNA may influence development of alcohol tolerance

In recent years, a class of small molecules known as microRNAs have been found to play an important role in regulating gene products in most animal and plant species.

New understanding of exaggerated mucous production and secretion in cystic fibrosis

A London, Canada scientist studying cystic fibrosis (CF) has successfully corrected the defect which causes the overproduction of intestinal mucous in mice.

Estrogen treatments may sharpen mental performance in some women

Estrogen treatments may sharpen mental performance in women with certain medical conditions, but University of Florida researchers suggest that recharging a naturally occurring estrogen receptor in the brain may also clear cognitive cobwebs.

Sleep gene - search is on!

While scientists and physicians know what happens if you don't get six to eight hours of shut-eye a night, investigators have long been puzzled about what controls the actual need for sleep.

Healthy children of Alzheimer's patients show early brain changes

Medical College of Wisconsin researchers in Milwaukee have reported that children of Alzheimer's patients who are carriers of a genetic risk factor for Alzheimer's disease have neurological changes that are detectable long before clinical symptoms may appear.

Cell mechanism discovery may lead to new treatments for cystic fibrosis, other inherited diseases

Researchers in Japan and Canada have discovered a key component of the quality control mechanism that operates inside human cells - sometimes too well. The breakthrough has significant implications for the development of new treatments for cystic fibrosis (CF) and some other hereditary diseases, the researchers say. Their results were published July 25 in the journal Science.

New biomarker for early cancer detection? Research reveals that 'microRNA' may fit the bill

Scientists at Fred Hutchinson Cancer Research Center have discovered that microRNAs - molecular workhorses that regulate gene expression - are released by cancer cells and circulate in the blood, which gives them the potential to become a new class of biomarkers to detect cancer at its earliest stages. Muneesh Tewari, M.D., Ph.D., and colleagues describe their findings in the July 28 issue of the Proceedings of the National Academy of Sciences.

Laboratory and mouse studies show targeted drug blocks the growth of breast cancer cells that spread to the brain

Using laboratory and mouse models of human breast cancer, researchers have found that a small molecule capable of targeting specific proteins on the surface of breast cancer cells can inhibit the growth of breast cancer cells that migrate to the brain.

Olympic doping - scientists race to stay ahead of the drug-taking and genetic manipulation

The race to ensure that scientists stop drug-taking athletes from damaging sport by using performance enhancing drugs or undergoing genetic manipulation is a constant challenge, according to a major four-decade review by three of the World's leading experts on doping in sport.

Statins reduce the risk of dementia by half

People at high risk for dementia who took cholesterol-lowering statins are half as likely to develop dementia as those who do not take statins, a new study shows.

Obesity gene makes it harder to tell if you feel full

A study involving more than 3,000 children in Britain has found those with a gene linked to obesity find it harder than others to tell when they are full.

Genome sequencing study reveals new genetic typhoid fever signatures

For the first time, next-generation DNA sequencing technologies have been turned on typhoid fever - a disease that kills 600,000 people each year. The results will help to improve diagnosis, tracking of disease spread and could help to design new strategies for vaccination.

Suprising finding on aging

Age may not be rust after all. Specific genetic instructions drive aging in worms, report researchers at the Stanford University School of Medicine. Their discovery contradicts the prevailing theory that aging is a buildup of tissue damage akin to rust, and implies science might eventually halt or even reverse the ravages of age.

New technique measures formation of clumps of proteins in protein-based pharmaceuticals

Scientists at the National Institute of Standards and Technology (NIST) have developed a technique to measure the formation of clumps of proteins in protein-based pharmaceuticals.
