The findings of the systematic review and meta-analysis, published Online First in The Lancet, suggest that investment in socioeconomic development (eg, better housing and improved education and nutrition) should be a vital part of efforts to control and eliminate malaria. http://medicalxpress.com/news/2013-06-world-poorest-children-malaria-poor.html Health Tue, 18 Jun 2013 18:30:01 EST news290793028 Inside each of us is our own internal timing device. It drives everything from sleep cycles to metabolism, but the inner-workings of this so-called "circadian clock" are complex, and the molecular processes behind it have long eluded scientists. But now, researchers at the Gladstone Institutes have discovered how one important protein falls under direct instructions from the body's circadian clock. Furthermore, they uncover how this protein regulates fundamental circadian processes—and how disrupting its normal function can throw this critical system out of sync. http://medicalxpress.com/news/2013-06-key-protein-linked-circadian-clocks.html Neuroscience Tue, 18 Jun 2013 17:00:06 EST news290760608 Behind the common expression "you can't compare apples to oranges" lies a fundamental question of neuroscience: How does the brain recognize that apples and oranges are different?

In response, health plans, consumer groups, and state governments are increasingly reporting health care prices. Despite recognition that price information must be relevant, accurate, and usable to improve the value of patients' out-of-pocket expenditures, and the potential for this reporting to affect health care organizations and prices, there are no data on what kind of price information is being reported," writes Jeffrey T.
