A Case Of Misidentification: Two Sharks Could Be Endangered -- Red Orbit

Confusion of identity between two shark species may threaten the survival of both. A new and unnamed shark species originally discovered off the Eastern United States seaboard discovered by Nova Southeastern University Oceanographic Center (NSU-OC) has a cousin that shares a striking resemblance: The endangered scalloped hammerhead shark.

Drone Aircraft Are No Longer Restricted To Military Use

Unblinking Eyes In The Sky -- The Economist

Technology and society: Drone aircraft are no longer restricted to military use. They are being built and used by hobbyists, activists and estate agents, among others. What are the implications for safety and privacy?

WHEN environmental activists start using drones to track down Japanese whaling vessels, as they did in December, it is a sure sign that UAVs (unmanned aerial vehicles) are no longer the sole prerogative of the armed forces. Police around the world are keen to use small pilotless aircraft to help them nab fleeing criminals and monitor crime scenes from above. With price tags of a little more (and, in some cases, a good deal less) than the $40,000 of a patrol car, a new generation of micro-UAVs is being recruited to replace police helicopters costing $1.7m and up.

U.S. Heavily Dependent On Military Space Technology

Hearings Show Our Dependence On Military Space Technology -- Washington Post

The United States may be falling behind in transportation, education and health care down here on Earth, but its military infrastructure is certainly way ahead when it comes to imagery and communications satellites armed with defensive and offensive capabilities out there in space.

That the United States leads in the militarization of space is apparent from House and Senate Armed Services subcommittee hearings this month on the fiscal 2013 budget of $9.7 billion for military space programs.

Jupiter Helps Halley’s Comet Give Us More Spectacular Meteor Displays -- Science Daily

ScienceDaily (Mar. 27, 2012) — The dramatic appearance of Halley's comet in the night sky has been observed and recorded by astronomers since 240 BC. Now a study shows that the orbital influences of Jupiter on the comet and the debris it leaves in its wake are responsible for periodic outbursts of activity in the Orionid meteor showers. The results will be presented by Aswin Sekhar at the National Astronomy Meeting in Manchester on the 27th of March.

Halley's comet orbits the Sun every 75-76 years on average. As its nucleus approaches the Sun, it heats up and releases gas and dust that form the spectacular tail. This outgassing leaves a trail of debris around the orbit.

Nuclear Fusion Is A Real Possibility, New Models Suggest -- Live Science

If new computer simulations pan out in the real world, nuclear fusion, the power source that makes stars shine, may be a practical possibility here on Earth, scientists say.

Simulations at Sandia National Laboratories in New Mexico revealed a fusion reactor that surpasses the "break-even" point of energy input versus energy output, indicating a self-sustaining fusion reaction. (This doesn't break any laws of physics for the same reason that starting a fire with a match doesn't).

International Space Station Nearly Struck By Space Junk

International Space Station Nearly Struck By Space Junk: Six Astronauts Nearly Had To Abandon Ship After A Piece Of A Russian Rocket Nearly Collided With The International Space Station -- Chicago Tribune/US News and World Report

Sometime Friday afternoon, the six people--including two Americans--aboard the International Space Station got a warning: Head into the nearest Russian Soyuz spacecraft and wait for further instructions, because a chunk of a disabled Russian rocket was hurtling towards them at speeds of over 17,000 miles per hour.

The threat of man-made space debris is increasingly becoming a problem for astronauts and the nearly 700 satellites orbiting earth. NASA estimates there are about 19,000 man-made objects orbiting earth--at orbital speeds, even a tiny particle can destroy satellites or cause serious damage to the space station.

Military Robot Shaves Human Head

Short-Circuit, Back And Sides: Military Robot Shaves Human Head -- Daily Mail

The drastic change of image that comes with having your head shaved is scary enough – but one man doubled the terror by letting a robot do the job for him.

The prototype robot was a Multi-Arm UGV (Unmanned Ground Vehicle) from U.S company Intelligent Automation Inc (IAI) in Maryland – and is designed to tackle IEDs, check backpacks for bombs and breach doors.

But on this occasion it was armed with multiple clippers to cut the hair of an IAI volunteer, who went through the ordeal to raise money for cancer charity the St. Baldrick's Foundation.

People Are Becoming More Selfish

Newer Generations Increasingly About “Me,” Study Finds -- Courtesy of the American Psychological Association and World Science Staff

oung Amer­i­cans care less and less about the the en­vi­ron­ment, pol­i­tics, and the world around them in gen­er­al, a study has found; even the idea of seek­ing a mean­ing­ful life is out of fash­ion.

In­stead, mon­ey, im­age and fame are the idols of our time.

“Pop­u­lar views of the mil­len­ni­al genera­t­ion, born in the 1980s and 1990s, as more car­ing, com­mun­ity-oriented and pol­i­tic­ally en­gaged than pre­vi­ous genera­t­ions are largely in­cor­rect, par­tic­u­larly when com­pared to ba­by boomers and Genera­t­ion X at the same age,” said the stu­dy’s lead au­thor, Jean Twenge, a psy­chol­o­gist at San Die­go State Uni­vers­ity and au­thor of the book Genera­t­ion Me. “These da­ta show that re­cent genera­t­ions are less likely to em­brace com­mun­ity mind­ed­ness and are fo­cus­ing more on mon­ey, im­age and fame.”

NASA Launches Five-Rocket Science Extravaganza At Last -- MSNBC/Space

ATREX mission studies high-level winds; glowing trails visible in skies over East Coast

At almost literally the last minute, NASA launched five suborbital sounding rockets early Tuesday on a mission to study high-level jet stream winds by creating artificial glowing clouds near the edge of space.

After several delays, the rockets started blasting off from their pads in Virginia just before the close of the day's scheduled launch window at 5 a.m. ET. The launches were held up until the very end by concerns about winds as well as boats that had strayed into the restricted range zone. But all the conditions turned "green" just in time for liftoff.

The Powerful Antioxidant Properties Of Popcorn

Popcorn Has More Antioxidants Than Fruit, Study Says -- FOX News

Long heralded as a low-calorie snack, new research indicates popcorn may actually be good for your health in other ways as well.

Pennsylvania researchers reported popcorn actually contains more healthy antioxidants called polyphenols than fruits and vegetables. The study found that there were 300 mg of polyphenols in a serving of popcorn, compared to 160 mg in a serving of fruit.

Polyphenols have been shown in prior studies to boost cardiovascular health as well as protect against chronic diseases.

How Turbines Can Replace A Heart

Man With No Pulse: How Turbines Can Replace A Heart -- New Scientist

You no longer need a heartbeat to be alive. In a groundbreaking surgery last year, doctors William Cohn and Bud Frazier from the Texas Heart Institute in Houston replaced a dying man's heart with twin turbines, resulting in the first living person without a pulse.

In this short film called Heart Stop Beating, directed by Jeremiah Zagar, you can follow the revolutionary procedure. Compared to artificial hearts that mimic real ones, the device is thought to be much more durable, since it has no flexible membranes or complex twisting mechanisms. "No one has been able to make a self-contained pulsatile device that can last more than two years or so and most wear out sooner," says Cohn.
