E-cigarettes leads to smoking

Seeing people use electronic cigarettes increases the urge to smoke among regular combustible cigarettes users, according to a new study of young adult smokers. This elevated desire is as strong as when observing someone smoking a regular cigarette, report scientists from the University of Chicago in Tobacco Control. The study is the first to investigate the behavioural effects of exposure to e-cigarette use in a controlled setting.“E-cigarette use has increased dramatically over the past few years, so observations and passive exposure will no doubt increase as well,” said study author Andrea King, PhD, professor of psychiatry and behavioral neuroscience at the University of Chicago.

early death likely due to diabetes

People with diabetes have about double the risk of premature death as people without diabetes. Studies have shown that they have about twice the odds of suffering from depression, which increases their mortality risk. A new UCLA-led study published in the journal of the American Geriatrics Society found that among adults 65 and older with diabetes, depression is linked with a greater chance for early death compared to people without depression. The researchers suggest that the higher mortality rate could stem from the fact that depressed people are less likely to adhere to their prescribed medications, diet, exercise and glucose self-monitoring than their non-depressed counterparts.

early detection of alzheimer’s?

In March, a team of Georgetown University scientists published research showing that, for the first time ever, a blood test has the potential to predict Alzheimer's disease before patients start showing symptoms. AACC has announced a late-breaking session at the 2014 AACC Annual Meeting & Clinical Lab Expo in Chicago which will expand upon this groundbreaking research and discuss why it could be the key to curing this devastating illness. According to the World Health Organization, the number of Alzheimer's patients worldwide is expected to skyrocket from the 35.6 million individuals who lived with it in 2010 to 115.4 million by 2050. Currently, however, all efforts to cure or effectively treat the disease have failed.

learning early is good for brain

Using your brain, particularly during adolescence, may help brain cells survive and could impact how the brain functions after puberty. According to a recent study in Frontiers in Neuroscience, Rutgers behavioural and systems neuroscientist Tracey Shors, who co-authored the study, found that newborn brain cells in young rats that were successful at learning survived while the same brain cells in animals that didn't master the task died quickly. “In those that didn’t learn, three weeks after the new brain cells were made, nearly one-half of them were no longer there,” said Shors, professor in the Department of Psychology and Center for Collaborative Neuroscience at Rutgers.

odour enhances attractiveness

A  research from the Monell Chemical Senses Center reveals that women's faces are rated as more attractive in presence of pleasant odours. In contrast, odour pleasantness had less effect on the evaluation of age. The findings suggest that use of scented products such as perfumes may, to some extent, alter people’s perceptions. “Odour pleasantness and facial attractiveness integrate into a joint emotional evaluation. This may indicate a common site of neural processing in the brain,” said lead author Janina Seubert. Scented products have been used for centuries as a way to enhance overall personal appearance.
