Investigators at the Stanford University School of Medicine have learned the signal that tumor cells display on their surfaces to protect themselves from being devoured by the immune system also plays a role in enabling atherosclerosis, the process underlying heart attacks and strokes.

Walking briskly on a regular basis may be more effective than vigorous jogging for improving glucose control in individuals with pre-diabetes, according to research from Duke Health. The findings, published online July 15 in the journal Diabetologia, are the result of a randomized, six-month study of 150 participants, each of whom was designated as having pre-diabetes based on elevated fasting glucose levels.

The current Zika epidemic in Latin America is likely to burn itself out within three years, suggests new research. The findings, from scientists at Imperial College London, also conclude that the epidemic cannot be contained with existing control measures. The team, who published their findings in the journal Science, predict the next large-scale epidemic is unlikely to emerge for at least another ten years - although there is a possibility of smaller outbreaks in this time.

Overweight or obese women who lost weight through diet or a combination of diet and exercise also significantly lowered levels of proteins in the blood that help certain tumors grow, according to a Fred Hutchinson Cancer Research Center study published July 14 in Cancer Research, a journal of the American Association for Cancer Research.

Are pomegranates really the superfood we've been led to believe will counteract the aging process? Up to now, scientific proof has been fairly weak. And some controversial marketing tactics have led to skepticism as well.

Parkinson's disease (PD) is the second most common neurodegenerative disorder that causes a range of motor and non-motor symptoms. During the course of the disease, dopamine (DA)-producing neurons are lost and bundles of proteins known as Lewy bodies (LBs) form in the brain.

University of Warwick research indicates that eating more fruit and vegetables can substantially increase people's later happiness levels.
