Dilute bleach neutralizes the mold allergens that cause most mold-related health complaints

Researchers at National Jewish Medical and Research Center have demonstrated that dilute bleach not only kills common household mold, but may also neutralize the mold allergens that cause most mold-related health complaints.

Study clarifies insulin's role in blocking release of energy in patients with type II diabetes

Chronically high levels of insulin, as is found in many people with obesity and Type II diabetes, may block specific hormones that trigger energy release into the body, according to researchers at the University of California, San Diego (UCSD) School of Medicine.

O-GlcNAc sugar is a critical regulator of cells' natural life cycle

The discovery reveals that, when disturbed, this process could contribute to cancer or other diseases by failing to properly control the steps and timing of cell division, the researchers say. The findings are described in the Sept. 23 issue of the Journal of Biological Chemistry, available online now.

Researchers determine the sequence in which the malaria parasite disperses from the red blood cells it infects

Researchers at the National Institute of Child Health and Human Development have determined the sequence in which the malaria parasite disperses from the red blood cells it infects. The National Institute of Child Health and Human Development is one of the Institutes comprising the National Institutes of Health.

Sperm testing in UK labs fails to meet World Health Organization standards

Teams from the Universities of Bristol and Sheffield found only five per cent of the clinics met all WHO standards for assessing the size and shape of sperm.

New way to "image" the internal chemistry of bacteria

As part of the search for better ways to track and clean up soil contaminants, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University have developed a new way to "image" the internal chemistry of bacteria.

Pigment explains why red heads are more at risk of skin cancer

A team of scientists have discovered that tiny chemical differences in how our skin reacts to ultraviolet light could explain why red heads are more likely to suffer skin cancer.

Using muscle tissue from tarantulas scientists discover how muscles relax

Using muscle tissue from tarantulas, an HHMI international research scholar and his colleagues have figured out the detailed structure and arrangement of the miniature molecular motors that control movement.

Immune system more concerned with damage detected than foreign invaders, such as viruses

A well-respected researcher who is now a chief of an immunology laboratory of the National Institutes of Health (NIH) has rocked the boat in the past few years for the experts in the understanding of the autoimmune system.

How negatively charged lipids stick to negatively charged DNA and self-organize into structures

Scientists studying the structure and interaction of negatively charged lipids and DNA molecules have created a "cookbook" for a class of nontoxic DNA delivery systems that will assist doctors and clinicians in the safe and effective delivery of genetic medicine.

New prostate cancer test could save thousands from unnecessary surgery

Doctors at present lack a test that can distinguish fast-developing tumours that need urgent attention from slow-growing ones that are not a threat and need only watching, and as a result many men have operations that can leave them impotent and incontinent for prostate tumours that would never have killed them.

Open nephron-sparing surgery remains the most desirable for the patients

Urologists often view less-invasive surgery techniques as more desirable for the patient, but in a study of open nephron-sparing surgeries (NSS) from 1985 to 2001 at Mayo Clinic, researchers found that the "gold standard" of open surgery for kidney tumors should remain the first choice for many patients. The study appears online today in The Journal of Urology.

Faster and more objective way to examine the surfaces of fossilized teeth

Using a powerful microscope and computer software, a team of scientists from Johns Hopkins, the University of Arkansas, Worcester Polytechnic Institute and elsewhere has developed a faster and more objective way to examine the surfaces of fossilized teeth, a practice used to figure out the diets of our early ancestors.

New breast cancer genes detected using cutting edge technology

Scientists in the UK say they have detected four new genes believed to be involved in the development of breast cancer.

New insights into dietary divergences between some of our human ancestors

A Penn State researcher is part of the team that developed techniques that have generated insights into dietary divergences between some of our human ancestors, allowing scientists to better understand the evolutionary path that led to the modern-day diets that humans consume.

Laser scissor-and-tweezers technology called RoboLase performed across the Pacific

In an effort to combine sophisticated laser and Internet technologies, scientists in Australia have successfully performed laser surgery and "optical trapping" in a Southern California laboratory via the Internet.

Tool helps determine who is at high risk of death after prostate cancer recurrence following surgery

Researchers at Johns Hopkins and The Brady Urological Institute have identified three risk factors and developed a simple reference tool that doctors can use to determine who is at high risk of death after prostate cancer recurrence following surgery.

Decreased breast cancer survival associated with high TRAIL-R2 expression

High expression of TRAIL-R2, a cell surface receptor that triggers cell death, has been shown to be associated with a decrease the survival rates of breast cancer patients according to a study published by Yale Cancer Center researchers in Clinical Cancer Research.

Percutaneous core-needle biopsy, provides samples of tissue suitable for accurate initial diagnosis of a solid tumor

Inserting biopsy needles through the skin appears to be a safe and reliable alternative to surgery for obtaining diagnostic samples of a suspected solid tumor in children, according to results of a study by investigators at St. Jude Children's Research Hospital.
