Researchers say high-priced cigarettes and smoke-free homes effectively reduce smoking behaviors among low-income individuals – a demographic in which tobacco use has remained comparatively high.
Early-stage lung and prostate cancers, as well as their recurrence, can be detected with a simple blood test, according to a study. Serum-free fatty acids and their metabolites may be used as screening biomarkers to help diagnose early stages of cancer, a
Women who watch their weight and closely follow a Mediterranean-style diet high in vegetables, vegetable oils, fish and beans may increase their chance of becoming pregnant.
Variant Creutzfeldt-Jakob disease (vCJD) is a degenerative brain disease -- often called the human form of bovine spongiform encephalopathy (BSE) or "mad cow disease." It emerged after widespread exposure to BSE prions in the late 1980s and earl
An analysis of data previously gathered on more than 3,000 elderly Americans strongly suggests that taking certain blood pressure medications to control blood pressure may reduce the risk of dementia due to Alzheimer's disease.
Scientists are enhancing the natural antioxidant properties of an element found in a car's catalytic converter to make it useful for medical applications.
In two parallel projects, researchers have rewritten the genetic code of the bacterium E. coli. In the first study they created a genetically and biochemically novel organism by erasing every example of a single codon from the entire genome. In the second
A team of researchers made an important discovery that could better explain some inherited forms of hearing loss in humans. Scientists identified a group of proteins crucial for shaping the cellular organ responsible for detecting sounds.
Researchers have created a peptide (a small piece of protein), linked to a light-responsive dye, capable of switching 'on' death pathways in cancer cells. The peptide remains inactive until exposed to external light pulses which convert it into a cell dea
Moderate to severe psoriasis is associated with an increased risk of chronic kidney disease independent of traditional risk factors, such as diabetes and heart disease, finds a study.
A team of scientists has isolated viruses that eat bacteria -- called phages -- to specifically target the highly infectious hospital superbug Clostridium difficile (C. diff.).

Using mice, researchers showed for the first time that the space between brain cells may increase during sleep, allowing the brain to flush out toxins that build up during waking hours. These results suggest a new role for sleep in health and disease.
In some areas of Africa, farmers, scientists and policymakers are beginning to win the war on hunger. Several factors have come together in recent years to tip the scales and increase food production.
In an analysis that included more than 40,000 women exposed to the nausea medication metoclopramide in pregnancy, use of this drug was not associated with significantly increased risk of major congenital malformations overall, spontaneous abortion, and st
Findings from a pivotal Phase 3 clinical trial that was designed to demonstrate the safety, efficacy, and acceptability of the Council's investigational one-year contraceptive vaginal ring have presenting positive results.
Scientists have proposed that the most recently discovered ancient human relatives – the Denisovans – somehow managed to cross one of the world’s most prominent marine barriers in Indonesia, and later interbred with modern hu
A new report shows that the use of both effective and risky drug therapies by Medicare patients varies widely across US regions, offering further evidence that location is a key determinant in the quality and cost of the medical care that patients receive
A new study has discovered profound abnormalities in brain activity in a group of retired American football players. Although the former players in the study were not diagnosed with any neurological condition, brain imaging tests revealed unusual activity
A team of engineers and doctors has developed a new wireless capsule that can give surgeons back their sense of touch when performing minimally invasive surgery.
