What, Exactly, Happens When Drone Meets Head?

Thanks to a dummy we now have a better idea of what happens when a drone hits a person’s head. A study by researchers at Virginia Polytechnic Institute and State University (Virginia Tech) one of the Federal Aviation Administration’s UAS (unmanned aircraft systems) test sites, suggests that commercial-sized drones can cause a wide range of injuries to people on the ground. In the United States, drone flights over people are not permitted. However, the FAA has been entertaining widespre

Growing Up Neanderthal

Though his life was short — he never reached the age of 8 — his fossil remains could have far-reaching influence in hominin research. A paper to be published Friday in Science reveals the discovery of the well-preserved skeleton of a Neanderthal boy who lived in Spain 49,000 years ago. The researchers discuss the fits and starts of adolescent growth for our biological cousins, leading to insights into the evolutionary development of Homo sapiens. Dental evidence reveals that the boy wa

Jellyfish Sleep, Too

Bees, sharks, anteaters, humans, we all share the need for sleep. Why we do it is of course still largely a mystery, but the fact of it remains incontrovertible. Now, new research on jellyfish is pushing the origin of sleep even further back down the evolutionary tree, before even the appearance of brains. It's long been known that any creature with a central nervous system needs to sleep, but jellyfish are effectively brainless. They do have neurons arranged into a "nerve net" throughout

Study: Mysterious Bursts From Space Occur Every Second

Fast radio bursts (FRBs) are one of the hottest topics in astronomy right now. These short but extremely powerful bursts last only milliseconds, but release tremendous amounts of energy during that minute period of time. Since publication of their initial discovery in 2007 (the burst itself occurred in 2001), just over 25 of these sources have been identified, with only one repeater. But now, Harvard-Smithsonian Center for Astrophysics astronomers have estimated that despite only the handful

Discovering our Common Humanity through Space Archaeology

Like many people, I was first introduced to the world of archaeology by Indiana Jones, that adventuresome character who lit up the big screen rescuing artifacts from villains by the skin of his teeth. Indy was awesome and will always have a place in my heart. But while he succeeded in making archaeology seem romantic, I never understood why it was important or believed I could join the adventure until I was introduced (via the small screen) to a real life archaeologist named Sarah Parcak.

Hackers Could Use Light to Steal Information Via Security Cameras

Where there’s a will, there’s a way, and hackers have plenty of will and countless ways to attack a secure network—even if it’s not connected to the internet. In the latest demonstration proving no network is safe, researchers at Ben-Gurion University of the Negev used security cameras equipped with night vision to send and receive data from a network that wasn’t even connected to the internet. Firewalls, intrusion detection and prevention systems… Jumping the Gap Organizations with

Ivan Ivanovich Cleared the Way for Yuri Gagarin’s Spaceflight

The countryside near Perm in the Soviet Union was rocketed by what sounded like an explosion in the afternoon of March 25, 1961. A capsule was falling from the sky, and before it hit the ground an ejection seat shot out, sending a passenger to a soft landing not far away. When recovery crews and volunteer helpers finally reached the landing site they rushed to the lifeless figure lying on the snowy ground, eyes wide open staring at nothing in the distance. One man punched the body in the fac

Oldest African DNA Offers Rare Window Into Past

A great irony about Africa is that, even though it's the birthplace of our species, we know almost nothing about the prehistoric populations who lived there: the bands of hunter gatherers who moved across the massive continent, interacting with and sometimes replacing other groups. Today that changes. Thanks to new research that includes the oldest African DNA ever successfully read, we're seeing Africa's prehistory like never before. Archaeologists and paleogeneticists are finally sta

We’re still on track to experience the second or third warmest year globally in records dating back to 1880

Last month was among the very warmest on record, according to two new analyses – and the heat is very likely to continue. With less than four months left to go in 2017,  the year will probably come in as second or third warmest on record. Two agencies have produced very slightly different verdicts for this past August. NASA's Goddard Institute for Space Studies has found that last month was the second warmest August globally in 137 years of modern record-keeping, surpassed only by Augu

Dinosaur Diet Discovery: “Plant-Eater” Snacked On Crustaceans

Like that vegetarian friend of yours who sneaks a piece of bacon when no one's looking, it appears that at least some dinosaurs previously thought to be dedicated herbivores occasionally consumed critters. That's at least according to new research that involved getting up close and investigative with those goldmines of lifestyle information: coprolites. Researchers took a look at fossilized feces from more than 15 separate deposits within the Kaiparowits Formation of Utah. The Kaiparowi
