For years, scientists have struggled to decipher the genetic instruction book that details where and when the 20,000 genes in a human cell will be turned on or off. Different genes operate in each cell type at different times, and this careful orchestration is what ultimately distinguishes a brain cell from a liver or skin cell. Scientists have developed a model of gene expression in yeast that pr...... [Show More]

Those diagnosed with early stage dementia can slow their physical, mental and psychological decline by taking part in therapeutic programs that combine counseling, support groups, Taiji and qigong, researchers report. Some of the benefits of this approach are comparable to those achieved with anti-dementia medications.

The hormones that make women physically stronger, more competitive and better able to deal with stress also tend to redistribute fat from the hips to the waist, according to one anthropologist. So in societies and situations where women are under pressure to procure resources, they may be less likely to have the classic hourglass figure.

Scientists have created a clinical tool to identify those at highest risk for having undetected hyperglycemia, impaired fasting glucose and undiagnosed diabetes. If these conditions are identified early, patients may benefit from preventative strategies that can minimize progression to diabetes, other diseases and mortality.

Scientists have proposed a new method to estimate the approximate time of death. This is based on the analysis of several substances from the vitreous humor of the eye of cadavers, according to an article published in the journal Statistics in Medicine. Using this system, scientists have developed a piece of software that makes it possible to establish precisely the post mortem interval (PMI&#...... [Show More]
People who manage to control HIV on their own are providing scientists with valuable information about how the immune system eliminates virus-infected cells. A new study identifies specific characteristics of the immune cells that successfully destroy HIV-infected cells and may drive strategies for developing the next generation of HIV vaccines and therapies.

Pear-shaped people who carry weight in the thighs and backside have been told for years they are at lower risk for high blood pressure and heart disease than apple-shaped people who carry fat in the abdomen. But in two studies, School of Medicine researchers report that body shape isn’t the only marker of risk. Excess liver fat appears to be the key to insulin resistance, cholesterol abnorma......

With up to half of a person?s body mass consisting of skeletal muscle, chronic inflammation of those muscles ? which include those found in the limbs ? can result in significant physical impairment. Researchers have found that vitamin E shows promise in easing inflammation.

Moderate alcohol intake is associated with higher levels of omega-3 fatty acids in plasma and red blood cells. The study suggests that wine does better than other alcoholic drinks. This effect could be ascribed to compounds other than alcohol itself, representing a key to understand the mechanism lying behind the heart protection observed in moderate wine drinkers.

Researchers have identified a gene that directly affects the production of a form of hemoglobin that is instrumental in modifying the severity of the inherited blood disorders sickle cell disease and thalassemia. The discovery could lead to breakthrough therapies for sickle cell disease and thalassemia, which could potentially eliminate the devastating and life-threatening complications of these d......

The sun’s magnetic field may have a significant impact on weather and climatic parameters in Australia and other countries in the northern and southern hemispheres. According to a study in Geographical Research, the droughts are related to the solar magnetic phases and not the greenhouse effect.
The study uses data from 1876 to the present to examine the correlation between solar cycles an...... [Show More]
New Optics For Improved Solar Power Generators Researchers are hoping to achieve higher solar cell efficiency involves using special coatings on solar cells that split light into colors like blue and red, which scientists estimate will increase efficiency by 50 percent.

The white lemuroid possum (Hemibelideus lemuroides), an Australian marsupial that lives only in the higher altitude rainforests of far north Queensland, may be the first species of mammal to go extinct because of global warming. This animal resembles a furry, snow-white lemur, with a prehensile tail and large eyes for nocturnal vision, and cannot survive sustained temperatures above 86 d...... [Show More]
