After waking up, the concentration of the stress hormone cortisol in saliva rises considerably; this is true not only for grown-ups but for babies as well.
Can HIV be transformed into a biotechnological tool for improving human health? According to a team of scientists, the answer is yes. Taking advantage of the HIV replication machinery, the researchers have been able to select a specific mutant protein. Added to a culture of tumor cells in combination with an anticancer drug, this protein improves the effectiveness of the treatment at 1/300 the normal dosage levels.
Catheter ablation for atrial fibrillation (Afib) is safe and suppresses arrhythmia recurrences in 74% of patients after a single procedure, according to new results. The survey also showed that arrhythmia-related symptoms such as palpitations, shortness of breath, fatigue or dizziness - present in 86% of patients before the ablation - were significantly reduced.
Researchers have decoded a signal path that could boost the burning of body fat. Mice that are missing a signal switch called VASP are clearly leaner and have more of the coveted brown and beige-colored fat cells that convert energy into heat. This might point the way to a new method for fighting obesity.
Disruptions to the circadian rhythm can affect the growth of blood vessels in the body, thus causing illnesses such as diabetes, obesity, and cancer, according to a new study.
Cytomegalovirus (CMV) is one of the viruses that most infected people carry without ill effects. Once infected you are infected for life and, although it normally is dormant, it can become active again at any point in time. New research shows that CMV infection is a significant risk factor for the type 2 diabetes in the elderly.
New research reassessing clinical data from trials, which investigate ways of treating side effects of therapy for prostate cancer, finds that tamoxifen, an anti-estrogen used to treat breast cancer, is also able to suppress gynecomastia and breast pain in men. Prostate cancer is one of the most common cancers in men and early treatment is usually very successful.
A new study raises a cautionary note about the increasing use of a minimally invasive procedure to repair ruptured abdominal aortic aneurysms.
In a study to decipher clues about how prostate cancer cells grow and become more aggressive, urologists have found that reduction of a specific protein is correlated with the aggressiveness of prostate cancer, acting as a red flag to indicate an increased risk of cancer recurrence.
When it comes to cooking, grocery shopping and playing with children, American moms with full-time jobs spend roughly three-and-half fewer hours per day on these and other chores related to their children’s diet and exercise compared to stay-at-home and unemployed mothers.
Living in poverty is often accompanied by conditions that can negatively influence cognitive development. Can being bilingual counteract these effects?

Separated and divorced couples are increasingly using emails, texting and social media to communicate with their ex-partners about their children. However, when ex-spouses use that technology to withhold or manipulate information, the children are the ones who suffer most, according to a family studies expert. A new study suggests divorce counselors should teach separated parents effective ways to use communication technology in order to maintain healthy environments for their children.
