BEIJING, Aug. 23 (Xinhuanet) -- More than 90 percent of U.S. heart attack patients who need the lifesaving procedure receive it within just 90 minutes of being admitted to the hospital, according to a study released Monday in the journal Circulation.The study on the American Heart Association's journal shows that in 2010, 91 percent of heart attack patients who needed angioplasty were treated within the 90-minute window. While in 2005, 44% were.Researchers analyzed data on more than 300,000 such patients who underwent emergency angioplasty between January of 2005 and October of 2010.The improvement is the result of a nationwide effort between federal agencies, health care organizations and health care providers to improve heart attack care and outcome, said study author Dr. Harlan M. Krumholz, a professor of medicine and epidemiology and public health at Yale University School of Medicine, according to U.S. News reports.

JERUSALEM, July 25 (Xinhua) -- A new study carried out by a Tel Aviv University researcher indicates that the common backache may not only be caused by bad positions or aging, but also by your genes.Prof. Gregory Livshits of the Sackler Faculty of Medicine says that genes play a major role in back pain, especially in the lower back, and in spinal deterioration.In a decade-long project with 2,500 identical and non-identical twins, Livshits found that, in one Arab family, the same back problems appeared in all the members of the family, whether young or old.According to the study, non-identical twins were three times more likely to have back pain, while identical twins were six times more likely to have the same back problems.Livshits believes the discovery of the link between back pains and genes could lead to much better treatment.The research was developed in collaboration with a team of scientists at Kings College, London, led by Prof. Tim Spector and Dr. Fran Williams and was recently published in the journal " Annals of the Rheumatic Diseases."In order to better investigate the genetic causes for one of the world most common pains, Livshits and his colleagues hope to put together an international consortium of research groups.

CANBERRA, Sept. 1 (Xinhua) -- Bushranger Ned Kelly's headless body has finally been identified in Australia, more than 130 years after his execution in the Old Melbourne Gaol, Victoria's Attorney- General Robert Clark announced on Thursday.Clark said the bushranger's remains have been identified by doctors and scientists at the Victorian Institute of Forensic Medicine (VIFM).Kelly was an Irish Australian bushranger, considered by some merely a cold-blooded killer, while by others a folk hero and symbol of Irish Australian resistance against oppression by the British ruling class for his defiance of the colonial authorities. He was hanged for murder in 1880 at Old Melbourne Gaol. His daring and notoriety made him an iconic figure in Australian history, folklore, literature, art and film.The project involved collaboration with the ancient DNA laboratory EAAF in Argentina, which has worked with the VIFM on other forensic projects.Clark said "This is an extraordinary achievement by our forensic team here in Victoria," he told reporters in Melbourne on Thursday."To think a group of scientists could identify the body of a man who was executed more than 130 years ago, moved and buried in a haphazard fashion among 33 other prisoners, most of whom are not identified, is amazing." The investigation started when a skull believed to belong to Kelly was handed to the VIFM on Nov. 11, 2009.The skull handed in in 2009 was found not to be that of Ned Kelly, and Glenrowan historian Gary Deans said the next step is to find Kelly's skull."The Government should put a request in the public arena for the return of Ned Kelly's skull," he told ABC News."We know thanks to Jack Cranston, who held the skull around 1929, that it was sitting on a detective's desk. This was around the same time that remains were dug up in the Old Melbourne Gaol."I imagine that that detective or somebody else took it home."

WASHINGTON, Sept. 14 (Xinhua) -- The U.S. space agency NASA unveiled plans on Wednesday for a deep space rocket to carry astronauts to the moon, Mars and other destinations beyond the International Space Station.The Space Launch System, or SLS, will be designed to carry the Orion Multipurpose Crew Vehicle, as well as important cargo, equipment and science experiments to Earth's orbit and destinations beyond. Additionally, the SLS will serve as a backup for commercial and international partner transportation services to the International Space Station."This launch system will create good-paying American jobs, ensure continued U.S. leadership in space, and inspire millions around the world," NASA Administrator Charles Bolden said in a statement. "President Obama challenged us to be bold and dream big, and that's exactly what we are doing at NASA. While I was proud to fly on the space shuttle, kids today can now dream of one day walking on Mars."The SLS rocket will incorporate technological investments from the Space Shuttle program and the Constellation program in order to take advantage of proven hardware and cutting-edge tooling and manufacturing technology that will significantly reduce development and operations costs.The first developmental flight, or mission, is targeted for the end of 2017, according to NASA.

WASHINGTON, July 27 (Xinhua) -- Astronomers studying observations taken by NASA's Wide-field Infrared Survey Explorer (WISE) mission have discovered the first known "Trojan" asteroid orbiting the sun along with Earth, the U.S. National Aeronautics and Space Administration (NASA) announced Wednesday in a statement.Trojans are asteroids that share an orbit with a planet near stable points in front of or behind the planet. Because they constantly lead or follow in the same orbit as the planet, they never can collide with it. In our solar system, Trojans also share orbits with Neptune, Mars and Jupiter. Two of Saturn's moons share orbits with Trojans.Scientists had predicted Earth should have Trojans, but they have been difficult to find because they are relatively small and appear near the sun from Earth's point of view."These asteroids dwell mostly in the daylight, making them very hard to see," said Martin Connors of Athabasca University in Canada, lead author of a new paper on the discovery to be published Thursday in the journal Nature. "But we finally found one, because the object has an unusual orbit that takes it farther away from the sun than what is typical for Trojans. WISE was a game-changer, giving us a point of view difficult to have at Earth 's surface."The WISE telescope scanned the entire sky in infrared light from January 2010 to February 2011. Connors and his team began their search for an Earth Trojan using data from NEOWISE, an addition to the WISE mission that focused in part on near-Earth objects, or NEOs, such as asteroids and comets. NEOs are bodies that pass within 28 million miles (45 million kilometers) of Earth 's path around the sun. The NEOWISE project observed more than 155, 000 asteroids in the main belt between Mars and Jupiter, and more than 500 NEOs, discovering 132 that were previously unknown.The team's hunt resulted in two Trojan candidates. One called 2010 TK7 was confirmed as an Earth Trojan after follow-up observations with the Canada-France-Hawaii Telescope on Mauna Kea in Hawaii.The asteroid is roughly 1,000 feet (300 meters) in diameter. It has an unusual orbit that traces a complex motion near a stable point in the plane of Earth's orbit, although the asteroid also moves above and below the plane. The object is about 50 million miles (80 million kilometers) from Earth. The asteroid's orbit is well-defined and for at least the next 100 years, it will not come closer to Earth than 15 million miles (24 million kilometers).
