People with low levels of LDL cholesterol are more likely to have Parkinson’s disease than people with high LDL levels, according to University of North Carolina at Chapel Hill researchers.
How a potentially deadly bacterium that could be used as a bioterrorist tool eludes being killed by the human immune system is now better understood, researchers report in the December issue of the Journal of Leukocyte Biology.
Memories of our life stories may be reinforced while we sleep, MIT researchers report December 17 in the advance online edition of Nature Neuroscience.
A tiny implant now being developed at MIT could one day help doctors rapidly monitor the growth of tumors and the progress of chemotherapy in cancer patients.
A University of Virginia neuroscientist has found that women under stress who hold their husbands’ hands show signs of immediate relief, which can clearly be seen on their brain scans.
Biologists at Washington University in St. Louis have discovered a large biological clock in the smelling center of mice brains and have revealed that the sense of smell for mice is stronger at night, peaking in evening hours and waning during day light hours.
Do animals use their two nostrils to locate scents in the same way they use two ears to locate sounds? UC Berkeley neuroscientists Noam Sobel and Jess Porter set out to test that question, using human volunteers on all fours to track a chocolate scent through the grass. With other senses blocked by gloves, earplugs and a blindfold, they were able to track scents and did better with two open nostrils than one.
Although online virtual experiences may improve a consumer’s knowledge of a product, the marketing tactic can backfire by creating a false sense of what the product’s real capabilites are, says a University of Washington professor of marketing.
The herbal supplement black cohosh does not relieve hot flashes among women going through menopause. In this double-blinded randomized controlled trial of 351 women, researchers found no significant difference between the numbers of hot flashes in women taking various forms of black cohosh compared to women taking a placebo. Hormone therapy, on the other hand, significantly reduced the frequency of hot flashes.
Those close to the World Trade Center on September 11, 2001, have, on average, more vivid memories of the terrorist attacks than do those who were in other parts of New York City on that day, according to a study by researchers at New York University. The results, reported in the most recent issue of the Proceedings of the National Academy of Sciences, indicate personal involvement may be important in engaging the amygdala when recalling 9/11 events.
