Earwax: A new frontier of human odor information (2/28/2014)

Scientists from the Monell Center have used analytical organic chemistry to identify the presence of odor-producing chemical compounds in human earwax. Further, they found that the amounts of these compounds differ between individuals of East Asian origin and Caucasians. The findings suggest that human earwax, an easily obtained bodily secretion, could be an overlooked source of personal information. ...> Full Article


What do women want? It depends on the time of the month (2/28/2014)

A UCLA meta-analysis of research on changes in mate preferences across the menstrual cycle suggests that ovulating women have evolved to prefer mates who display sexy traits, such as a masculine body type, dominate behavior, certain body odors and masculine facial features, rather than traits that are generally desirable in a long-term mate. ...> Full Article


No clowning around: Juggling sheds light on how we run (2/27/2014)

No clowning around: Juggling sheds light on how we runJuggling may seem like mere entertainment, but engineers used this circus skill to gather critical clues about how vision and the sense of touch help control the way humans and animals move their limbs in a repetitive way, such as in running. The findings eventually may aid in the treatment of people with neurological diseases and could lead to prosthetic limbs and robots that move more efficiently. ...> Full Article


Exercise may slow progression of retinal degeneration (2/26/2014)

Exercise may slow progression of retinal degenerationModerate aerobic exercise helps to preserve the structure and function of nerve cells in the retina after damage, according a Feb. 12 in The Journal of Neuroscience. The findings suggest exercise may be able to slow the progression of retinal degenerative diseases. Age-related macular degeneration, one of the leading causes of blindness in the elderly, is caused by the death of light-sensing nerve cells in the retina called photoreceptors. ...> Full Article

Study shows yogurt consumption reduces the risk of type 2 diabetes (2/22/2014)

New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) shows that higher consumption of yogurt, compared with no consumption, can reduce the risk of new-onset type 2 diabetes by 28 percent. Scientists at the University of Cambridge found that in fact higher consumption of low-fat fermented dairy products, which include all yogurt varieties and some low-fat cheeses, also reduced the relative risk of diabetes by 24 percent overall. ...> Full Article


A short stay in darkness may heal hearing woes (2/21/2014)

A short stay in darkness may heal hearing woesCall it the Ray Charles Effect: a young child who is blind learns to hear things others cannot. Researchers know that young brains are malleable enough to re-wire some circuits that process sensory information. Now researchers at the University of Maryland and Johns Hopkins University have shown the brains of adult mice can also be re-wired, compensating for vision loss by improving their hearing. This may lead to treatments for human hearing loss. ...> Full Article


Study suggests whole diet approach to lower CV risk has more evidence than low-fat diets (2/21/2014)

A study published in The American Journal of Medicine reveals that a whole diet approach, which focuses on increased intake of fruits, vegetables, nuts, and fish, has more evidence for reducing cardiovascular risk than strategies that focus exclusively on reduced dietary fat. By analyzing major diet and heart disease studies conducted over the last several decades, investigators found that participants directed to adopt a whole diet approach instead of limiting fat intake had a greater reduction in cardiovascular death and non-fatal myocardial infarction. ...> Full Article


Research results show new way for cholesterol treatment (2/20/2014)

A basic research project from Aarhus University now sheds new light on the pharmaceutical industry's new hope in the field of cholesterol treatment.

Shivering could elicit some of the same benefits as exercise (2/19/2014)

It's common knowledge that shivering in the cold is part of the body's attempt to stay warm. According to new research into the mechanisms involved, shivering releases a hormone that stimulates fat tissue to produce heat so that the body can maintain its core temperature. This hormone, irisin, is also produced by muscle during exercise. The findings demonstrates that the act of shivering produces calorie-burning brown fat and improves metabolism. ...> Full Article

Whether your lose or gain weight depends on weekdays (2/16/2014)

Whether your lose or gain weight depends on weekdaysAlmost everyone loses weight on weekdays and gains weight on weekends. What separates the slim from the heavy isn't how much more they gain on weekends. It's how much they lose during the weekdays. In this study, Dr. Brian Wansink from Cornell University, in collaboration with researchers from the VTT Technical Research Centre of Finland and Tampere University of Technology, looks into the impact that the seven-days-a-week human cycle has on weight. ...> Full Article

Shrinking brain volume is a sign of Alzheimer's disease as well as normal aging. ...> Full Article


Humans can use smell to detect levels of dietary fat (2/4/2014)

New research from the Monell Center reveals humans can use the sense of smell to detect and discriminate levels of dietary fat in food. As food smell almost always is detected before taste, the findings identify one of the first sensory qualities that signals whether a food contains fat. Innovative methods using odor to make low-fat foods more palatable could someday aid public health efforts to reduce dietary fat. ...> Full Article
