A Johns Hopkins study has found that depression is an independent risk factor for coronary artery disease in men, with those experiencing clinical depression twice as likely to develop the condition. Symptoms of CAD appeared on average 15 years after the first episode of depression.
Conjugated linoleic acid (CLA) has been shown to reduce atherosclerosis in cholesterol-fed rabbits, eliminating some fat already present. The Wistar Institute, established in 1892, is making history through its development of vaccines and discovery of molecules helping the immune system fight diseases.
A study by pediatricians from Wake Forest University found that gay teenage boys with multiple male partners are more likely to experience violence, drug abuse, and absence from school. The researchers suggest that clinicians can apply these findings to provide targeted support for these adolescents.
Researchers analyzed data from over 72,000 screening mammograms to show a steady increase in cancer detection across all ages, with no abrupt jump at 50. The study challenges previous conclusions that suggested an age-related change in mammography's effectiveness, supporting the continued use of screening for women aged 40-49.
Researchers from the Max Planck Institute for Chemistry studied the stability of materials relevant to the lower mantle under very high pressures and temperatures. Their findings indicate that partial melting is more likely than previously thought to explain seismic anomalies in this region.
Adolescents born to US-born parents show poorer health and riskier behavior compared to foreign-born youth. Foreign-born teens have better physical health and are less likely to engage in delinquent or violent acts.
Materials scientists will use microgravity conditions to study material formation and behavior, producing high-value products. The U.S. Laboratory Module will house three Materials Science Research Racks, with each rack capable of conducting various experiments.
Researchers at the University of Delaware developed a new technique to produce extremely thin alumina films with an electrical storage capacity three times greater than silicon dioxide. These films could potentially eliminate reliability problems in semiconducting circuits by storing more electricity and reducing current-blocking flaws.
