A young adult's personality may hold clues to his or her health later in life, so perhaps doctors should assess their patients' personalities during checkups, a new study says. Among those who were the least conscientious as young adults, 45 percent went on to develop health problems by age 38, such as high cholesterol, high blood pressure and gum disease, while just 18 percent of the most conscientious people developed one of these health problems, said study researcher Salomon Israel, of Duke University. Another personality trait, called "openness to experience," was also linked with better health later in life. People who score high in this personality trait tend to be curious, imaginative and prefer variety to routine.

SpaceX fired up the nine-engine first stage of a Falcon 9 rocket Saturday in a major preflight rehearsal before the March 16 launch of nearly 5,000 pounds of experiments and supplies to the International Space Station. The brief ignition of the Falcon 9's nine Merlin 1D engines occurred with the rocket firmly fastened to SpaceX's Complex 40 launch pad at Cape Canaveral, Fla. The engines generate about 1.3 million pounds of thrust at sea level. The engine firing came at the end of a multi-hour countdown, in which the SpaceX launch team loaded liquid oxygen and kerosene propellants into the two-stage Falcon 9 booster. A SpaceX spokesperson said the static fire was successful.

For people with knee osteoarthritis, taking the supplement glucosamine may not decrease the loss of knee cartilage or pain, at least in the short term, a new study finds. The study involved about 200 people with mild to moderate knee pain that is common among those with knee osteoarthritis. Participants were randomly assigned to drink either a glass of lemonade containing glucosamine, or plain lemonade (a placebo), every day for six months. At the end of the study, participants who took glucosamine were just as likely as those who took the placebo to experience loss of knee cartilage.

Malaysia Airlines Flight 370 took off from the Malaysian capital of Kuala Lumpur on Friday afternoon (March 7) U.S. Eastern time, headed for Beijing. The whereabouts of the Boeing 777 jet, which was carrying 227 passengers and 12 crew members, remain unknown. "This is a very unusual event," Sid McGuirk, an associate professor of air traffic management at Embry-Riddle Aeronautical University in Florida, told Live Science. Air traffic controllers track commercial jets using two types of radar.

An American astronaut and two Russians who carried a Sochi Olympic torch into open space landed safely and on time on Tuesday in Kazakhstan, defying bad weather and ending their 166-day mission aboard the International Space Station (ISS). "Safe arrival back on Earth," said a NASA TV announcer while all-terrain rescue and recovery vehicles were shown trundling across a snowy steppe to the Soyuz TMA-10M capsule. "The crew are reported to be in good health," NASA said. Inside the capsule were former ISS commander Oleg Kotov and flight engineers Sergei Ryazansky and Michael Hopkins from NASA.

By Sharon Begley NEW YORK (Reuters) - - As the U.S. Supreme Court prepares to hear a religious dispute over the Obamacare contraception mandate, advocates on both sides are trying to set the court straight on the science. While the Supreme Court will not be ruling on the science, and has never defined pregnancy, many groups have filed friend-of-the-court briefs offering their view of how emergency contraceptives work.

(This March 6 story has been corrected to fix spelling of test to verifi from Verify in paragraph 33) By Julie Steenhuysen LA JOLLA, California (Reuters) - When President Bill Clinton announced in 2000 that Craig Venter and Dr. Francis Collins of the National Human Genome Research Institute had succeeded in mapping the human genome, he solemnly declared that the discovery would "revolutionize" the treatment of virtually all human disease. The expectation was that this single reference map of the 3 billion base pairs of DNA -- the human genetic code -- would quickly unlock the secrets of Alzheimer's, diabetes, cancer and other scourges of human health. As it turns out, Clinton's forecast was not unlike President George Bush's "mission accomplished" speech in the early days of the Iraq war, said Dr. Eric Topol of Scripps Translational Science Institute, which is running a meeting On the Future of Genomic Medicine here March 6-7.

Researchers from the University of Sussex and the Amboseli Trust for Elephants played recordings of human voices to wild elephants in Kenya and watched how they reacted. "Our results demonstrate that elephants can reliably discriminate between two different ethnic groups that differ in the level of threat they represent," the authors said in an article published in the Proceedings of the National Academy of Sciences. The researchers said the findings provided the first proof elephants can distinguish between human voices, and suggested that other animals seeking to avoid hunters may also have developed this skill.

"We're using pretty sophisticated mathematics to better understand the role of sea ice in the climate system, and, ultimately, to improve our projections of climate change," Golden said in a talk Wednesday (March 6) at the Museum of Math in New York City. In high school and college, he studied the physics of sea ice, but his main interest was mathematics. "I loved sea ice, but I had no intention of building my career around it," Golden told Live Science. Later, he realized that sea ice could be modeled using the same math as composite materials, whose components contain different physical or chemical properties.
