Gunshot Wounds Are Getting Deadlier, One Hospital Finds

Just days after the deadliest mass shooting in U.S. history, a new study from Denver finds that deaths from gunshot wounds at a trauma center there have increased over the past decade and that gunshot injuries have become more severe. "Our study provides an objective measure of something trauma surgeons across the country already know: The firearms used in our communities are becoming more harmful and more lethal," said study co-author Dr. Angela Sauaia, a professor of public health, medicine and surgery at the University of Colorado Denver. During that time, a total of about 1,680 people were treated for gunshot wounds at the hospital, and the number of people hospitalized yearly for gunshot injuries was about the same from year to year, according to the findings.

NASA to set fire in space for science, safety

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - An unmanned cargo ship pulled away from the International Space Station on Tuesday to stage the first of three planned NASA experiments on how big fires grow in space, an important test for astronaut safety. Previous experiments in space were limited to the incineration of samples no bigger than an index card, said David Urban, lead researcher for the Spacecraft Fire Experiment, or Saffire. "We tried for years to find a vehicle and a circumstance where this would work and initially we'd get a 'not on my spacecraft' reaction," Urban said during a NASA TV interview.

Asymmetric molecule, key to life, detected in space for 1st time

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Scientists for the first time have found a complex organic molecule in space that bears the same asymmetric structure as molecules that are key to life on Earth. The researchers said on Tuesday they detected the complex organic molecule called propylene oxide in a giant cloud of gas and dust near the center of the Milky Way galaxy. Akin to a pair of human hands, certain organic molecules including propylene oxide possess mirror-like versions of themselves, a chemical property called chirality.

Stegosaurus had bite like a sheep

Professor Paul Barrett, dinosaur researcher at London's Natural History Museum, said advanced technology has given exciting new insights into dinosaur biology - something that would not have been possible several years ago. "Stegosaurus was actually an animal that could get up to 9 metres in length and weigh several tonnes," Barrett said while holding a Stegosaurus tooth. Lead author Dr Stephan Lautenschlager, a post-doctoral researcher at the University of Bristol, used engineering software to give the digital skulls the material properties to match as closely as possible to the real thing.

How Kevlar Saved an Orlando Police Officer's Life

A helmet made of Kevlar saved the life of an Orlando, Florida, police officer on Sunday (June 12) after police engaged in a gun battle with a man who killed 49 people and injured 53 others at a gay nightclub, according to news sources. Thanks to its unique chemistry, Kevlar body armor has saved the lives of countless people who were wearing it. In a tweet Sunday morning, the Orlando Police Department applauded the tough fiber: "Pulse shooting: In hail of gunfire in which suspect was killed, OPD officer was hit.

Mysterious Monumental Structure Found at Ancient Petra

Carved into desert cliffs, the towering, ancient city of Petra can trace its origins back at least 2,000 years. For two centuries, archaeologists have extensively studied what is left of Petra, but they continue to make new discoveries. By combining data gathered by Google Earth and satellite sensors, they observed the shape of what may have once been a giant stoneplatform, located about 0.6 miles (900 m) outside Petra's city center.
