Community-level ART coverage, male circumcision linked to decline in new male HIV infections in Uganda

Increasing the number of men who undergo circumcision and increasing the rates at which women with HIV are given antiretroviral therapy (ART) were associated with significant declines in the number of new male HIV infections in rural Ugandan communities, new Johns Hopkins Bloomberg School of Health research suggests.

Research sheds more light on midlife memory decline

The inability to remember details, such as the location of objects, begins in early midlife and may be the result of a change in what information the brain focuses on during memory formation and retrieval, rather than a decline in brain function, according to a study by McGill University researchers.

Sugar-binding protein galectin-9 could be new weapon to fight HIV

The ultimate impediment to a cure for HIV infection is the presence of latent, HIV-infected cells, which can reawaken and produce new virus when antiretroviral drug therapy is stopped.

Gut microbiota could influence person's likelihood of developing colon cancer

The microscopic organisms that live in our gut do more than help us digest food. A new study in rats bolsters a growing body of evidence that the complex mix of microorganisms found in the gut, known as gut microbiota, could influence a person's likelihood of developing colon cancer.

Changes in cavefish metabolism could lead to new insights into diabetes

Cavefish that live in dark caves with only sporadic access to food show symptoms similar to diabetes, but don't appear to experience any health problems.

Researchers discover new biological pathway involved in Alzheimer's disease

Researchers have identified a new biological pathway involved in Alzheimer's disease. In experiments using fruit flies, blocking the pathway reduced the death of brain cells, suggesting that interfering with the pathway could represent a promising new strategy to treat the disease in human patients.

Impact of diet may depend on individual’s genetic composition

If you've ever seen a friend have good results from a diet but then not been able to match those results yourself, you may not be surprised by new findings in mice that show that diet response is highly individualized.

Researchers study how skin stem cells respond to forces

All cells share the same genetic code, no matter if they are skin or brain cells. However, these cells are exposed to very different types of mechanical environments and mechanical stresses.

Study reveals problems encountered when trying to avoid plastic exposure

The well-known documentary "Plastic Planet" by Werner Boote starkly illustrates the dangers of plastic and synthetics for human beings and also shows how ubiquitous plastic is.

Researchers identify PKD1 protein as potential cause for impaired insulin signaling in diabetics

Medication can help trigger the enzyme that kick starts insulin production in the body, but the drugs don't always work for those who are obese or diabetic, and most need to regulate their glucose and insulin levels. That's why a recent discovery made by Rudy Valentine and a team of researchers holds so much promise.

Scientists identify timing of major metabolic shift in developing neurons

Our brains can survive only for a few minutes without oxygen. Salk Institute researchers have now identified the timing of a dramatic metabolic shift in developing neurons, which makes them become dependent on oxygen as a source of energy.

New ultra-fast approach to modeling protein interactions may pave way for drug development

Protein-protein interactions (PPIs) are the basis of cellular functions, and when these processes are compromised diseases such as cancer emerge. For years scientists have tried with mixed success to map out PPIs to understand cellular processes.

Researchers investigate role of OXTR gene in binge eating

A study by York University researcher Caroline Davis and her colleagues at the Centre for Addiction and Mental Health is the first to demonstrate that variants of the Oxytocin Receptor gene contribute to why some of us overeat or engage in episodes of binge eating.

HANS device helps prevent fatal craniovertebral junction injuries in racecar drivers

Before 2001, catastrophic craniovertebral junction (CVJ) injuries were the most common cause of death to drivers in the fast-paced sport of professional car racing. That changed with the development and implementation of the HANS (Head and Neck Support) device and similar restraints.
