Supplements gone awry.

Pregnant women are told they need folate to ensure proper neurodevelopment of their babies, but new research from the Johns Hopkins Bloomberg School of Public Health suggests there could be serious risks in having too much of it.

Want to see social inequality and how it impacts obesity? Look at takeout food in your neighborhood - and in the halls of Cambridge.

Yet the halls of Cambridgee are where a new paper claims takeout food is an indicator of social inequality. Obviously elites at Cambridge have a long and cherished history to gaze upon, including one in which a feudal system made sure poor people were never overweight. Today, there is more equality than ever, poor people can afford to be fat, but the Cambridge scholars believe that even cheap food is a way of promoting oppression.

The Centre for Diet and Activity Research (CEDAR) at the University of Cambridge mapped takeout food to obesity and income. Prestige, the kind of paper British comic John Oliver just ridiculed is born:

Ontario rotavirus hospitalizations drop 71% after launch of infant vaccine program

Immunizing babies against rotavirus in Ontario led to a 71% drop in hospitalizations for the infection, new research from Public Health Ontario (PHO) and the Institute for Clinical Evaluative Sciences (ICES) has shown.

Antibiotic-resistant bacteria most often are associated with hospitals and other health-care settings, but a new study indicates that chicken coops and sewage treatment plants also are hot spots of antibiotic resistance.

The research, led by a team at Washington University School of Medicine in St. Louis, is published May 12 in Nature.

The scientists surveyed bacteria and their capacity to resist antibiotics in a rural village in El Salvador and a densely populated slum on the outskirts of Lima, Peru. In both communities, the researchers identified areas ripe for bacteria to shuffle and share their resistance genes. These hot spots of potential resistance transmission included chicken coops in the rural village and a modern wastewater treatment plant outside Lima.

From our vantage point on the ground, the sun seems like a still ball of light, but in reality, it teems with activity. Eruptions called solar flares and coronal mass ejections explode in the sun's hot atmosphere, the corona, sending light and high energy particles out into space. The corona is also constantly releasing a stream of charged particles known as the solar wind.

But this isn't the kind of wind you can fly a kite in.

Scientists from Princeton University and NASA have confirmed that 1,284 objects observed outside Earth's solar system by NASA's Kepler spacecraft are indeed planets. Reported in The Astrophysical Journal on May 10, it is the largest single announcement of new planets to date and more than doubles the number of confirmed planets discovered by Kepler so far to more than 2,300.
