A person's mere presence in a room can add 37 million bacteria to the air every hour -- material largely left behind by previous occupants and stirred up from the floor -- according to new research by Yale University engineers. "We live in this microbial soup, and a big ingredient is our own microorganisms," said Jordan Peccia, associate professor of environmental ... (read more)
The molecular response of an organism -- be it mouse or man -- to pathogenic invasion is controlled by circadian rhythms, researchers found. In mice exposed to infection at the highest and lowest time of activity in the 24-hour light-dark cycle of an immune protein known as toll-like receptor 9 (TLR9), those whose exposure was at the nadir of TLR9 expression had much more severe sepsis, according to Erol Fikrig, MD, ...

More bad news for soda lovers: in addition to obesity and heart disease, the sugary drinks may be tied to asthma and chronic obstructive pulmonary disease (COPD), Australian researchers found. People who consumed at least a half a liter of soft drinks a day were more than twice as likely to develop either lung condition compared with those who didn't partake at all (OR 2.33, 95% CI 1.51 to 3.60), Zumin Shi, MD, of the Universi...

Yale researchers have uncovered the molecular tricks used by bacteria to fight the effects of fluoride, which is commonly used in toothpaste and mouthwash to combat tooth decay. In the Dec. 22 online issue of the journal Science Express, the researchers report that sections of RNA messages called riboswitches -- which control the expression of genes -- detect the build-up of fluoride and activate th...

Tanning beds have already been linked to an increased risk of the deadliest type of skin cancer and now new research shows they can also raise the odds of developing the most common form of the disease. Scientists at the Yale School of Public Health in New Haven, Connecticut found that young people who tanned on the indoor beds had a 69 percent increased chance of suffering from early-onset basal cell c...

Teenagers who were abused as young children show changes in their brains that put them at risk for behavioral problems in adulthood, according to research from Yale University. Brain scans of adolescents who suffered physical abuse and neglect showed differences in the part that controls executive function -- mental processes such as planning, organizing and focusing on details -- according to a...

A new report from Yale University found that beverage companies are targeting children, particularly black and Hispanic youths, in their sales campaigns for sodas, fruit, energy and sports drinks. A report released today from Yale's Rudd Center for Food Policy and Obesity said that children and teens were exposed to double the amount of television ads for full-calorie and sugary bever...
