This engineered growth factor could benefit people with chronic wounds, including those with diabetes or compromised immune systems, according to the researchers, whose work is detailed in the Feb. 21 issue of the journal Science. Growth factors are proteins that animals produce naturally; When an injury happens, growth factors signal certain types of cells to come to the injury site, and help heal the wound.

Melting Snow Electrocutes People, Pets But those ice-free sidewalks and roadways may hold an even more dangerous threat: death by electrocution. Several blocks of busy Sixth Avenue in downtown Manhattan were cordoned off to pedestrians and vehicles yesterday (Feb. 19), following reports of a powerful electric current surging through sidewalk grates, manhole covers and the doorknobs of nearby buildings, Gothamist reported. The problem was a defective electric cable, according to service provider Consolidated Edison (Con Ed). Con Ed later admitted that her death was the result of poorly insulated electrical wires.

The satellite, built by Boeing, was carried into space aboard an unmanned Delta 4 rocket, which blasted off from Cape Canaveral Air Force Station in Florida at 8:59 p.m. EST/0159 Friday GMT. The Delta 4 rocket was built and launched by United Launch Alliance, a partnership of Lockheed Martin and Boeing, under contract with the U.S. Air Force. Once in position 12,000 miles above the planet, the new satellite will replace a 16-year-old member of the GPS constellation, one that already has lasted more than twice as long as expected.

Researchers analyzed blood samples from 191 men with prostate cancer who also had at least two relatives with prostate cancer. The researchers analyzed their DNA, looking for mutations in 22 known cancer genes. They found 13 mutations in eight genes that were linked with aggressive prostate cancer.

They did, however, find other damning evidence that contributed to his mother's 2010 conviction in North Carolina: DeVarion had three rib fractures at different stages of healing — evidence of a history of abuse. "If he hadn't been decomposed, we probably would not have seen any of them," said Ann Ross, an anthropologist at North Carolina State University who examined DeVarion's remains. About 9.2 children per 1,000 in the United States were victims of child abuse in 2012, while 2.1 per 100,000 lost their lives to it in 2011, according to annual data.

Researchers at Johns Hopkins University's School of Medicine in Baltimore tracked brain activity as two jazz musicians played pieces from memory and then engaged in back-and-forth improvisation, creating something akin to a spontaneous musical conversation. They found that areas of the brain associated with syntax and language were very active as the musicians were improvising. "The areas of the brain related to language ramped way up when the musical behavior was spontaneous between the two musicians," said Charles Limb, an associate professor in the department of otolaryngology-head and neck surgery at Johns Hopkins and senior author of a new study published today (Feb. 19) in the journal PLOS ONE.

Lockheed enables Apache helicopter pilots to see targets in color By Andrea Shalal HUNTSVILLE, Alabama (Reuters) - The U.S. Army has unveiled new technology that will for the first time allow AH-64 Apache helicopter pilots to see targeting and surveillance data in full, high-resolution color, instead of the fuzzy black and white images they get now. An Army official said new sensors developed by Lockheed Martin Corp over the past four years could help avoid mistakes such as the 2007 attack by two U.S. Apache helicopters that killed 12 people in Baghdad, including two Reuters news staff, after they were mistaken for armed insurgents. U.S. Central Command has said an investigation of the incident found that U.S. forces were not aware of the presence of the news staffers and believed a camera held by one of the men was a rocket-propelled grenade launcher. "This additional situational awareness ... will give soldiers what they need to make the right decisions on the battlefield," Army Lieutenant Colonel Steven Van Riper, the Army's product manager for the Apache sensors, told reporters when asked if the new technology help avert such mistakes. Read More »Stress Causes Headaches, Scientists Confirm Perhaps it's no surprise to anyone who has had a splitting migraine after a miserable day, but doctors have solidified the link between stress and headaches. Although headaches can be triggered by many factors, ranging from muscle strain to exposure to noxious gases, stress clearly plays a major role, according to a study released today (Feb. 19) which will be presented at a neurology research meeting in April. Conversely, participants who reported little stress in their lives had few, if any, headaches. For the study, the researchers grouped headaches into four categories: tension headaches, which are the most common, and involve intense pressure or muscle ache anywhere from the neck to the forehead; Read More »The Odd Ways Pregnancy Can Cause Vision Problems Read More » As Olympics Inspires Your 'Inner Athlete', Beware Common Injuries (Op-Ed) Dr. Jason Lipetz is a physician with the department of Physical Medicine and Rehabilitation in the North Shore-LIJ Health System. The combination of New Year's resolutions and the media surrounding the Winter Olympics in Sochi might encourage many people to embark upon fitness regimens, participation in exercise, and sports which they have not played in some time — and a re-evaluation of diet. For some, this might involve beginning a gym membership. Others might introduce an outdoor or indoor aerobic exercise regimen in the form of running or cycling, although this winter those in the northeast might find particular difficulty finding a clean track or pavement. During this introduction of exercise and athletics, it is essential to start gradually and with proper instruction and technique.

The Black-Tailed Antechinus has been found in the high-altitude, wet areas of far southeast Queensland and northeast New South Wales. "It's frenetic, there's no courtship, the males will just grab the females and both will mate promiscuously," Andrew Baker, head of the research team from the Queensland University of Technology who made the discovery, told Reuters.

"The use of the sites does not seem to be decreasing, and therefore it might be time to come up with better approaches to provide what the public is looking for in a more open, transparent and trustworthy manner," Hanauer said.

Sadomasochism Leads to Altered States, Study Finds Consensual sadomasochism was long considered pathological, but psychologists studying people interested in BDSM (bondage, discipline, sadism and masochism) have failed to find evidence that these sexual practices are harmful. If sadomasochism is not a pathology as once believed, the question is why some people engage in these painful sexual behaviors, said James Ambler, a graduate student in psychology at Northern Illinois University. "It seems, on the surface, very paradoxical," Ambler told Live Science. Read More »Pooperoni?

During the last three flu seasons, adults in this age group have accounted for about 35 to 40 percent of flu hospitalizations, according to the CDC. Deaths in this age group are also up: This flu season, about 60 percent of flu deaths have been among those ages 25 to 64. "Younger people may feel that influenza is not a threat to them, but this season underscores that flu can be a serious disease for anyone," Dr. Tom Frieden, director of the CDC, told reporters today (Feb. 20).
