For sufferers of sleep apnea, erectile dysfunction is often part of the package. New research indicates that ED in cases of obstructive sleep apnea syndrome may be linked to the chronic intermittent hypoxia — oxygen deprivation — that patients with OSAS experience during episodes of obstructed breathing.

The precise timing of the origin of life on Earth and the changes in life during the past 4.5 billion years has been a subject of great controversy for the past century. The principal indicator of the amount of organic carbon produced by biological activity traditionally used is the ratio of the less abundant isotope [...]

New findings about the causes of mad cow disease show that sometimes it may be genetic. Until several years ago, it was thought that the cattle prion disease bovine spongiform encephalopathy — also called BSE or mad cow disease — was a foodborne disease.

For up to a million women, enjoying a piece of pepperoni pizza has painful consequences. They have a chronic bladder condition that causes pelvic pain. Spicy food, as well as citrus and caffeine, can intensify the pain, which is so intense some women inject lidocaine into their bladders. Researchers previously thought chemicals from the food [...]

The war against malaria in tropical countries was fought and lost in the 20th century on the basis of faulty intelligence, a ‘dodgy dossier’ which argued that the same methods used to tackle the disease in temperate countries would also work in the tropics.
Using the molecular equivalent of a tattoo on DNA that adult stem cells pass to their “daughter” cells in combination with gene expression profiles, researchers have identified two early steps in adult stem cell differentiation — the process that determines whether cells will form muscle, neurons, skin, etc., in people and animals.

Marauding molecules cause the tissue damage that underlies heart attacks, sunburn, Alzheimer’s and hangovers. But scientists say they may have found ways to combat the carnage after discovering an important cog in the body’s molecular detoxification machinery.

Chemical scientists have shown that, bad as the traffic is, the most harmful air pollution in Mexico City may not come from burning fossil fuels. Instead the culprit may be garbage incineration.
