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.
Smell :: Sniffers show that humans can track scents, and that two nostrils are better than one
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.
This party doesn’t start until the hosts arrive
Disease-causing organisms can be present in some areas where their hosts are not. If their hosts arrive, novel disease outbreaks may result. In the first comprehensive genetic analysis of an invasive marine host and its parasites, researchers trace invasion pathways of snails and trematodes from Japan to North America.
Menopause :: Black cohosh does not relieve menopausal hot flashes – Group Health
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.
Diabetes :: Less sugary drinks during childhood may cut disease risk
Symptoms of heart disease and diabetes usually seen in adults are increasingly being found in adolescents according to a longitudinal study, which suggests that reducing the intake of sugar-sweetened beverages during childhood may lessen the risk of chronic disease in later life.
