India's Mars mission a step closer to success with engine test
News ImageBy Aditya Kalra NEW DELHI (Reuters) - Indian scientists successfully tested the main engine of a spacecraft bound for Mars on Monday and performed a course correction that puts the low-cost project on track to enter the red planet's orbit. The $74-million mission will attempt to enter orbit around Mars early on Wednesday. If successful, it will be the first time a mission has entered Mars' orbit on its first attempt, enhancing India's position in the global space race. "Main liquid engine test firing successful ... ...

SpaceX breaks ground on Texas orbital launch facility
By Jim Forsyth SAN ANTONIO (Reuters) - Privately owned SpaceX started construction in south Texas on Monday for what the company said will be the first private commercial orbital launch facility in the world. Space Exploration Technologies Corp, the company's formal name, last year entered the commercial satellite launch market. It broke ground at the site near Brownsville, not far from the Mexican border. The Hawthorne, California-based company, owned and operated by technology entrepreneur Elon Musk, also flies cargo to the International Space Station under a $1.6 billion contract with NASA. ...

NASA robotic probe slips into orbit around Mars
News ImageBy Irene Klotz CAPE CANAVERAL Fla (Reuters) - A NASA robotic spacecraft fired its braking rockets on Sunday, ending a 10-month journey to put itself into orbit around Mars and begin a hunt for the planets lost water. After traveling 442 million miles (71 million km), the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft fired its six rocket thrusters, trimming its speed from 12,800 mph (20,600 kph) to 10,000 mph (16,093 kph). ...

Keep Your Pants, and Your Dignity, at the Hospital
Although the white coats that doctors wear have been scrutinized for their authoritarian look, the open-in-the-back gowns that hospital patients wear, and the effect these gowns have on patients' dignity and state-of-mind while in the hospital, have gone largely unexamined. "There are a number of ways in which the hospital system traumatizes patients, and one of those is that we take away the patients' clothes and put them in a somewhat depersonalizing, unisex blue gown, when that's not completely necessary," Dr. Todd Lee, an assistant professor of Medicine at McGill University in Montreal, told Live Science.

Tiny Implants Could Give Humans Self-Healing Superpowers
News ImageA new military-sponsored program aims to develop a tiny device that can be implanted in the body, where it will use electrical impulses to monitor the body's organs, healing these crucial parts when they become infected or injured. Known as Electrical Prescriptions, or ElectRx, the program could reduce dependence on pharmaceutical drugs and offer a new way to treat illnesses, according to the Defense Advanced Research Projects Agency (DARPA), the branch of the U.S. "The technology DARPA plans to develop through the ElectRx program could fundamentally change the manner in which doctors diagnose, monitor and treat injury and illness," Doug Weber, program manager for DARPA's biological technologies office, said in a statement. The implant that DARPA hopes to develop is something akin to a tiny, intelligent pacemaker, Weber said.

NASA Hails Mars Probe's 'Flawless' Arrival at Red Planet
NASA Hails Mars Probe's 'Flawless' Arrival at Red PlanetNASA's newest Mars spacecraft is safely in orbit around the Red Planet, and the probe's handlers couldn't be happier. The MAVEN spacecraft arrived at Marslate Sunday (Sept. 21) after a picture-perfect orbital insertion burn that slowed the probe down enough to be captured by the Red Planet's gravity in a feat that had mission team members cheering with excitement and relief. "Wow! What a night," MAVEN project manager David Mitchell, of NASA's Goddard Space Flight Center in Greenbelt, Maryland, said Sunday during a press briefing after the probe reached the Red Planet. "You get one shot with Mars orbit insertion, and MAVEN nailed it tonight." [See images from the MAVEN mission]

Hints of Mysterious Dark Matter Revealed by Cosmic Rays
News ImageA particle detector floating 250 miles (400 kilometers) above Earth has analyzed 41 billion cosmic-ray particles, and the data have revealed new insights into the mysterious and invisible dark matter that physicists believe makes up 27 percent of the universe. The Alpha Magnetic Spectrometer (AMS) detector aboard the International Space Station already gathered evidence of dark matterlast year, but the new results are the most precise measurements of cosmic-ray particles yet. They include 50 percent more data, and have revealed new insights into the origin of the particles found in cosmic rays, Samuel Ting, a professor of physics at MIT and an AMS spokesman, said during a live webcast at the CERN (the European Organization for Nuclear Research) lab in Switzerland yesterday (Sept. 18). Physicists theorized the existence of invisible, and so far undetectable, dark matter as a way to explain why galaxies and celestial bodies don't just unravel and fly apart.

Scientists see risk of mutant airborne Ebola as remote
News ImageBy Kate Kelland LONDON, Sept 19 (Reuters) - The Ebola virus raging through West Africa is mutating rapidly as it tears a deadly path through cities, towns and villages, but the genetic changes are for now not giving it the ability to spread more easily. Concern that the virus could gain capability to transmit through the air - creating a nightmare scenario of the disease being able to spread like a flu pandemic, killing millions - was fueled by a top infectious disease expert in the United States. ...

Ig Nobel Prizes 2014: Jesus Toast, Dog Poop and Raucous Science
News ImageThe brilliant minds behind research studies about how Earth's magnetic field affects pooping dogs and why people see Jesus in toast were honored tonight (Sept. 18) during one of the most purposefully ridiculous ceremonies in all of science: the Ig Nobel Prizes. Each year, the Ig Nobel Prizes (a parody of the somewhat more famous Nobel Prizes) are awarded to scientists whose research "makes people laugh and then think." Improbable Research, the organization that awards the prizes, runs the annual ceremony here at Harvard University's Sanders Theater. "The achievements speak for themselves all too eloquently," Master of Ceremonies Marc Abrahams said during tonight's Ig Nobel presentations. For example, this year's prize in Arctic science went to a group of researchers who dressed up like polar bears to see how reindeer in Norway would react compared with their reactions to humans.
