Scientists seeking to understand how to make an AIDS vaccine have found the cause of a major roadblock. It turns out that the immune system can indeed produce cells with the potential to manufacture powerful HIV-blocking antibodies -- but at

Researchers have provided the most extensive account to date of the unique observable characteristics seen in patients with an extremely rare premature aging syndrome.

Scientists have identified a protein switch that helps prevent liver damage, including inflammation, fibrosis and cancer. The findings suggest that a better understanding of how the protein, TAK1, works could lead to new insights into the development of liver disease

Among premature births -- children born before the 37th week of pregnancy -- newborn boys have a poorer prognosis than newborn girls. Physicians have explored why being male constitutes a risk factor for greater morbidity in these infants.

Patients with advanced prostate cancer are often treated with hormones, but when the tumors start growing again they have more and different blood vessels, reveals research from Sweden. This discovery paves the way for new treatments for hormone-resistant prostate cancer.

Although seen as a potential heart disease therapy, raising high-density lipoprotein cholesterol levels by inhibiting activity of a transfer protein may not be effective, a new study suggests. Scientists found an association between low plasma cholesterol ester transfer protein activity

A new study could point the way to the development of better drugs to fight a deadly form of childhood leukemia called mixed-lineage leukemia (MLL).

An overwhelming majority of people who have periodontal disease are also at high risk for diabetes and should be screened for diabetes, a nursing-dental research team has found. The researchers also determined that half of those at risk had seen

Scientists are the first to prove that the Notch signaling pathway targets heart muscle cells and thus reveal its crucial role in heart development and repair.

New research strengthens the link between longevity proteins called sirtuins and the lifespan-extending effects of calorie restriction.

Researchers are aiming to tackle diseases that affect millions -- such as asthma, blindness and clogged arteries -- by jamming 'sat nav'-like signals that drive the body to damage itself.

Researchers studying climate now have a new tool at their disposal: daily global measurements of carbon dioxide and water vapor in a key part of Earth's atmosphere. The data confirm the mainstream scientific view that large changes in the climate

People who have smaller fingers have a finer sense of touch, according to new research. This finding explains why women tend to have better tactile acuity than men, because women on average have smaller fingers.

An increase in the number of screened carriers for cystic fibrosis (CF) was associated with a decrease in the number of children born with CF in northeast Italy, according to a new study.

Do good-looking people really benefit from their looks, and in what ways? Researchers found that yes, attractive people do tend to have more social relationships and therefore an increased sense of psychological well-being.

A gene involved in some forms of intellectual disability has been identified. The gene is called TRAPPC9 and may be associated with hundreds of thousands of cases of intellectual disability world-wide.

A new study reveals that couples who share the responsibility for paid and unpaid work report higher average measures of happiness and life satisfaction than those in other family models.

The conversations neurons have as they form and recall memories have been decoded by scientists. The breakthrough in recognizing in real time the formation and recollection of a memory opens the door to objective, thorough memory studies and eventually better

Researchers have found that higher leptin (a protein that controls weight and appetite) levels were associated with a lower incidence of Alzheimer's disease and dementia. The study may open pathways for possible preventive and therapeutic interventions.

Significant associations exist between parent-reported insomnia symptoms and medical complaints of gastrointestinal regurgitation and headaches in young school-aged children, a new study shows.
