New genes that regulate longevity

In an effort to understand the molecular mechanisms that control aging, Howard Hughes Medical Institute researchers and their colleagues have now uncovered 10 new genes that regulate longevity in yeast. The studies also suggest a new model for how aging is slowed when caloric intake is restricted.

Possible viral cause of Kawasaki disease identified

In an important discovery in infectious disease research, a team of scientists from Northwestern University has identified a possible viral cause of Kawasaki disease, the most common cause of acquired heart disease in children in developed nations.

Mayo Clinic provides new strategy for designing better treatments for juvenile dermatomyositis

Mayo Clinic researchers, working with colleagues at the University of Minnesota and University of Pittsburgh, are the first to describe a new role for a specialized cell of the immune system in children suffering from a rare muscle-damaging disease known as juvenile dermatomyositis (JDM).

New Flu Chip can determine the genetic make-up of types of flu virus in 11 hours

A novel "Flu Chip" developed at the University of Colorado at Boulder that can determine the genetic signatures of specific influenza strains from patient samples within hours may help world health officials combat coming epidemics and pandemics.

Rapid screen-and-treat methods significantly reduce cervical cancer precursor lesions

A new study led by Columbia University Medical Center researchers demonstrates the safety and efficacy of two low-tech diagnostic tools to significantly reduce the prevalence of cervical cancer precursor lesions.

Number of color-sensitive cones in the human retina differs dramatically among people

First-ever images of living human retinas have yielded a surprise about how we perceive our world.

Scientists discover molecular structure related to cell growth and cancer

Researchers discovered a special type of molecular structure that helps keep genes properly turned off until the structure is ejected from those genes in a regulated manner to help turn the genes on.

Method to count the absolute number of individual protein molecules inside a living cell

Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, two basic hurdles for studying biology quantitatively.

New prostate cancer test far more accurate

At present in order to predict prostate cancer outcomes, doctors rely on measures that suggest how far the tumour has spread and how abnormal the cancer cells appear under the microscope.

New findings on brain tumors called ependymomas

Brain tumors called ependymomas that occur in different parts of the central nervous system appear to arise from subpopulations of stem cells called radial glia cells (RGCs), according to investigators at St. Jude Children's Research Hospital. The discovery explains why some identical-looking ependymomas are actually distinctly different diseases, the researchers said.

Curry spice appears to shut down a protein active in the spread of breast cancer

Curcumin, the main ingredient of turmeric and the compound that gives curry its mustard-yellow color, inhibits metastasis to the lungs of mice with breast cancer, report researchers at The University of Texas M. D. Anderson Cancer Center

Performing a sentinel node biopsy prior to mastectomy and reconstruction gives best results

Altering the standard step-by-step procedure that takes women facing a mastectomy from diagnosis to surgery to reconstruction can improve the process and help in determining if immediate reconstruction is the best course of action, according to new research from the University of North Carolina at Chapel Hill.

Pulsing heart cell provides clues into how heart disease develops

A pulsing heart cell is giving Oregon Health & Science University researchers insight into how it sends and receives signals, and that's providing clues into how heart disease and other disorders develop.

Discovery of molecule that causes transverse myelitis

Hopkins researchers have discovered a single molecule that is a cause of an autoimmune disease in the central nervous system, called transverse myelitis (TM), that is related to multiple sclerosis.

Chronically high levels of insulin may block specific hormones that trigger energy release into the body

Their findings, which may point to new approaches to developing improved treatment options for the disease, are published in the journal Nature.

Extreme gene pin-pointed

One teenager likes to snowboard off a cliff. Another prefers to read a book and wouldn't think of trading places. Why these differences exist is a mystery, but for the first time researchers have identified a possible genetic explanation behind risk-seeking behavior.

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.
