 Concentration counts in mind controlled drone race It was a test of concentration and brainwaves for students at the University of Florida during what was billed as the first mind controlled drone race. Sixteen competitors wearing special headsets measuring the electrical activity of their brains used their powers of concentration to send their drones down a 10-yard (meter) course to the finish line. The students used brain-computer interface (BCI) which enables a person to use brainwaves to control a computer or other device.

The illnesses were linked to contaminated office water coolers that were distributed to hundreds of companies in the cities of Barcelona and Tarragona. Norovirus is a common cause of foodborne illness outbreaks, and it can also contaminate drinking water, such as water from private wells, according to the Centers for Disease Control and Prevention.

In particular, there has been an increase in the percentage of children with severe obesity, the study found. From 2013 to 2014, 6.3 percent of U.S. children ages 2 to 19 had a body mass index (BMI) of at least 35, which is considered to be severely obese.

Bedbugs Have Favorite Colors Do bedbugs prefer their hiding places to be a certain color? Researchers conducted a series of tests in a lab to see if bedbugs (Cimex lectularius) would favor different-colored harborages, or places where pests seek shelter. The scientists found that bedbugs strongly prefer red and black, and typically avoid colors like green and yellow.

Lead author on the study Brook Chernet injected frog embryos with two types of genes, an oncogene to predispose them to cancer and another gene to produce light sensitive "ion channels" in tumor-type cells. Ion channels are passageways into and out of the cell that open in response to certain signals.

Scientists at Tufts University performed optogenetics experiments on frogs, often used in basic research into cancer because of the biological similarities in their tumors to those in mammals, to test whether this method already used in brain and nervous system research could be applied to cancer. "We call this whole research program cracking the bioelectric code," said biologist Michael Levin, who heads the Tufts Center for Regenerative and Developmental Biology.

| Wind energy converter inspired by ancient boats By Amy Pollock and Mohamed Haddad A bladeless wind energy convertor inspired by the sailing boats of Ancient Carthage is set to breeze past traditional turbines in terms of efficiency, according to its Tunisian developers. A Tunisian start-up has taken inspiration from the sailing boats of Ancient Carthage to develop a bladeless, non-rotating wind energy convertor that is more efficient than traditional turbines as well as safer and quieter, according to the developers. Tunis-based Saphon Energy says the aerodynamic bowl-shaped sail on its turbine is capable of capturing twice as much wind energy over the same swept area as a conventional turbine.

Despite being made from gold, the so-called "plasmonic absorber" is jet black as it absorbs 99 percent of light in the visible to mid-infrared spectrum. Its designers say this is a dramatic improvement over previous metal absorbers and comparable to the world's darkest material, carbon-nanotube (CNT) arrays.

However, the areas with the highest increases in drug overdose deaths are not always the places with the most drug trafficking, as identified by the government, the study found. This suggests that drugs are passing through some high-trafficking counties without affecting death rates of the people in those regions, but are causing problems in other parts of the country, the researchers said.

The woman came to see doctors in January 2015, seeking medical help for her paranoia about her husband's behavior, said Dr. C. Onur Noyan, a psychiatrist at NPIstanbul Neuropsychiatry Hospital in Istanbul who treated the woman and was the lead author of the case report. The doctors conducted a detailed psychiatric evaluation and concluded that the woman had experienced a brief psychotic attack, Noyan said.

People who said they ate while watching TV at least two times a week, or didn't plan how much to eat before they sat down to a meal, were more likely to gain weight, compared with people who didn't report engaging in these unhealthy eating behaviors. But many other behaviors that are typically thought of as unhealthy — including eating pre-cooked or canned foods, buying snacks from a vending machine, and eating at fast food restaurants more than once a week — were not linked to weight gain.
