Researchers ave shown that well-developed eyes come at a surprising cost to other organ systems. 

Researchers have long associated the presence of a well-developed brain with major energy consumption. This means that animals that develop advanced nervous systems require environments where this is possible. There has to be good access to nutrients, and every investment in an organ comes at a cost to some other organ system that is less essential in that particular environment. Up to now, there have been few concrete measurements of how high the cost of a nervous system actually is.

The study involving Mexican cavefish shows that the visual system can require between 5% and 15% of an animal's total energy budget.

Over one million people in sub-Saharan Africa will contract malaria this year because they live near a large dam, according to a new study which, for the first time, has correlated the location of large dams with the incidence of malaria and quantified impacts across the region. The study finds that construction of an expected 78 major new dams in sub-Saharan Africa over the next few years will lead to an additional 56,000 malaria cases annually.

Since the Food and Drug Administration (FDA) cautioned against using a minimally invasive method to treat fibroid tumors called power morcellation, there was a nearly quarter increase in hospital readmissions and 27 percent increase in major postoperative complications after hysterectomies in Michigan, a new University of Michigan study says.

After the first FDA safety communication in April 2014, the percent of women receiving minimally invasive hysterectomies in a large Michigan database also went down by an absolute 1.7 percent decrease.

The findings appear in the American Journal of Obstetrics&Gynecology.

More than half of Asian Americans and nearly half of Hispanic Americans with diabetes are undiagnosed, according to researchers from the National Institutes of Health and the Centers for Disease Control and Prevention. Additionally, prevalence of diabetes for all American adults went up, from nearly 10 percent to over 12 percent between 1988 and 2012. Diabetes prevalence - how common the condition is - also went up in every age, sex, level of education, income and racial/ethnic subgroup. One bright spot: The proportion of people with diabetes that was undiagnosed decreased 23 percent between 1988-1994 and 2011-2012.

The statistics account for age differences across the surveys.

Now that so many teenagers have smartphones equipped with cameras it’s inevitable that they’re used to take pictures, sometimes regrettable pictures, and to share them with others. The problem is that this is not just often regrettable in their own eyes, but also illegal in the eyes of the law.

A 14-year-old boy who took a naked selfie and sent it to a girl at school that he’d been flirting with recently found himself in hot water with his school and with the police. Both his and the girl’s details have been added to a police intelligence database for making and distributing an indecent image. Indecent because, as an image of a minor, it’s classified as child pornography under the Protection of Children Act 1978.

Want fries with that diet soda? You aren't alone, and you may not be saving as many calories as you think by consuming diet drinks, according to a new examination of the dietary habits of more than 22,000 U.S. adults which found that diet-beverage consumers may compensate for the absence of calories in their drinks by noshing on extra food that is loaded with sugar, sodium, fat and cholesterol.
