Rheinmetall tapped for laser light for Bundeswehr assault rifles

Business
July 6 (UPI) -- Rheinmetall has received a $ 5.9 million contract for laser light packages for the German Bundeswehr's Special Forces Assault Rifle. The order, announced this week by Rheinmetall, will provide 1,745 laser light packages to the Bundeswehr, with deliveries beginning in early 2019. The procurement falls under the Federal Office for Bundeswehr Equipment, Information Technology and In-service Support. The package features a Variable Tactical Aiming Laser which is designed for compactness and to be mounted on shorter assault rifles. The package includes two weapon lights, including a standard dual LED and a special version for hostage rescue operations. The work will be performed by Rheinmetall Soldier Electronics in Stockach, Germany. The Special Forces Assault Rifle is a modi...
Foods with carbs and fats together make the brain light up more, study finds

Foods with carbs and fats together make the brain light up more, study finds

Health
On a platter of cheese, pretzels and donuts, most people will probably reach for the donuts, according to a new study. That could be because the brain values foods like donuts, with both fats and carbohydrates, more than foods high in only fats, like the cheese, or only carbs, like the pretzels. People could be wired to want that deadly combo: Fats and carbohydrates together. "We were interested in exploring mechanisms that drive food reinforcement," lead author Dana Small, director of Yale University’s Modern Diet and Physiology Research Center, told ABC News. So how do the digestive and emotional system work for different types of macronutrients, like carbs and fats? And how do "man-made," processed foods that contain both fats and carbs affect these mechanisms? To find out, ...
Big banks get green light to make short-term, small dollar loans

Big banks get green light to make short-term, small dollar loans

Finance
Consumers who rely on payday loans to fill their budget gaps may have a new option to turn to: traditional banks. National banks just received the go-ahead to serve that market from their regulator, the Office of the Comptroller of the Currency. On Wednesday, Comptroller of the Currency Joseph Otting called for national banks and federal savings associations to step into the short-term, small-dollar installment loan market. These loans typically range from $ 300 to $ 5,000, according to the regulator. And that adds up to about $ 90 billion in loans ta...
Loss of receptor cells can prompt strong itching from a light touch: Study

Loss of receptor cells can prompt strong itching from a light touch: Study

Health
May 4 (UPI) -- A severe reaction to light touching -- often among old people -- occurs because of fewer receptors in the skin, according to a new study with mice.Researchers at Washington University School of Medicine in St. Louis studied severe itching from light tough, even when the skin is under clothing. Their findings, which researchers hope will lead to a treatment for the condition, were published Friday in the journal Science."Itching caused by touch becomes more common as we age and is especially problematic for people with dry skin or who already suffer from chronic itching," senior investigator Dr. Hongzhen Hu, an associate professor of anesthesiology at Washington University, said in a press release. "It can be more than a nuisance, and there are no drugs available to treat thi...
New nanoparticle could help solar panels convert unseen light into energy

New nanoparticle could help solar panels convert unseen light into energy

Science
April 23 (UPI) -- Scientists have developed a new nanoparticle that can absorb near-infrared light and reemit it as visible light, which could allow solar panels to convert unseen light into usable energy.Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory coated tiny particles in organic dyes. The dyes work like antennae, which allowed scientists to fine-tune the nanoparticle's light-converting properties."These organic dyes capture broad swaths of near-infrared light," Bruce Cohen, a scientist at Berkeley Lab's Molecular Foundry, said in a news release.Most solar technologies that focus on visible light fail to absorb near-infrared light, allowing a solid chunk of the solar spectrum to go to waste. Roughly 44 percent of all light that hits Earth's surface...
