|  Jesus' House? 1st-Century Structure May Be Where He Grew Up  | Jesus' hometown — in modern-day Israel have identified a house dating to the first century that was regarded as the place where Jesus was brought up by Mary and Joseph. It was first uncovered in the 1880s, by nuns at the Sisters of Nazareth convent, but it wasn't until 2006 that archaeologists led by Ken Dark, a professor at the University of Reading in the United Kingdom, dated the house to the first century, and identified it as the place where people, who lived centuries after Jesus' time, believed Jesus was brought up. Whether Jesus actually lived in the house in real life is unknown, but Dark says that it is possible.

When used together, five calculations that are done based a child's height and weight — such as how much a child's height varies from the average for age and gender, and how this measure changes over time — were able to detect celiac disease in 84 percent of boys and 88 percent of girls with the disorder, according to the study, published online today (March 2) in the journal JAMA Pediatrics. The findings echo other studies that have also found that children with celiac disease often weigh less and don't grow as fast or as tall as their typical peers, the researchers said. Furthermore, when the researchers looked back at the height of children already diagnosed with celiac disease, they found girls were shorter than expected for two years before they were diagnosed, and boys were shorter for one year before their diagnosis, when compared with a reference group. Read More » Peanut Eaters May Live Longer, Study Finds Peanuts may not only be a tasty snack but they may also help people live longer, a new study suggests. Researchers found that the people in the study who ate the most peanuts and tree nuts (such as walnuts, pecans and almonds) every day had a lower risk of dying over a five- or six-year period than the people who ate the least peanuts and tree nuts, or none of them. "We showed that peanuts have similar cardiovascular benefits to tree nuts," said study researcher Dr. Xiao-Ou Shu, a professor of medicine in the division of epidemiology at Vanderbilt University Medical Center in Nashville. "If people are not allergic to them, they should consider eating more peanuts for their heart-health benefits because they are cheaper and more affordable than other nuts," Shu said.

His paintings are in major collections and exhibited throughout the United States, and he regularly consults with NASA from his position as a cosmology researcher at Princeton University. He is also author of "Fly Me to the Moon" (Princeton University Press, 2007). Litho, from the Greek lithos, for stone, and panspermia from the Greek for "all seeds," the hypothesis suggests life began on Earth more than 4 billion years ago as the planet was under constant bombardment from the rocky debris of the early solar system.

Scientists with the Icelandic Meteorological Office declared an end to the six-month-long eruption on Saturday (Feb. 28). However, scientists will still watch for signs that magma is building pressure beneath Bardarbunga volcano, the source of Holuhraun's lava. A series of eruptions could take place in the coming months to years either underneath the volcano or in a different location, or Bardarbunga could go back to sleep.

The satellites, which make up NASA's Magnetospheric Multiscale mission (or MMS), will launch on March 12 from Florida's Cape Canaveral Air Force Station to study a phenomenon known as magnetic reconnection in the magnetic field around Earth. Magnetic reconnection occurs when magnetic field lines break apart and reconnect, releasing huge amounts of energy and charged particles — sometimes straight at the Earth. While scientists have studied magnetic reconnection for decades in an effort to better understand its relation to space weather and solar storms, the MMS satellites will be the first experiment to intentionally pass directly through areas where the phenomenon occurs and create a three-dimensional view of it, mission scientists said.

As a cardiologist and professor at The Ohio State University Wexner Medical Center, I partnered with a team of DMD experts from around the nation in a clinical trial that tested the combination of eplerenone (an aldosterone antagonist that serves as a potassium-sparing diuretic) and either a angiotensin-converting-enzyme (ACE) inhibitor or an angiotensin receptor blocker (ARB). In this human trial, we enrolled 42 boys with DMD who showed evidence of early heart muscle damage by cardiac magnetic resonance imaging.

NASA's Dawn spacecraft is scheduled to slip into orbit around Ceres — the largest object in the main asteroid belt between Mars and Jupiter — at 7:20 a.m. EST (1220 GMT) on Friday, March 6, wrapping up a deep-space chase that lasted two-and-a-half years. If all goes according to plan, Dawn will become the first spacecraft ever to orbit a dwarf planet, as well as the first to circle two celestial objects beyond the Earth-moon system. "It's clear that discoveries lie ahead, and Ceres will be revealed in stunning detail, just like Vesta," Dawn Deputy Principal Investigator Carol Raymond, of NASA's Jet Propulsion Laboratory in Pasadena, California, said during a news conference today (March 2).

The study of healthy young adults in Korea found that, compared with people who didn't drink coffee, those who drank three to five cups of java per day had a lower risk of having calcium deposits in their coronary arteries, which is an indicator of heart disease. The study participants who drank three to four cups had the lowest risk of developing clogged arteries seen in the study, said Dr. Eliseo Guallar, an epidemiologist at Johns Hopkins University Bloomberg School of Public Health in Baltimore, Maryland, and co-author of the study published today (March 2) in the journal Heart. "But the risk went down with just one cup per day," compared with the risk of people who drank no coffee, Guallar added. Read More » Hit the Sack!

The new scans are part of a large clinical trial called Anti-Amyloid Treatment in Asymptomatic Alzheimer's or A4, the first designed to identify and treat patients in the earliest stages of Alzheimer's, before memory loss begins. Patients accepted into the A4 trial already have deposits of beta amyloid, the other protein associated with Alzheimer's. The addition of the tau scan will allow scientists to get a much clearer picture of the events that lead to Alzheimer's. The disease affects 5 million Americans, and 16 million are projected to be afflicted by 2050. Dr. Reisa Sperling of Massachusetts General Hospital in Boston, who is leading the 1,000-patient trial, said tau is commonly found in small amounts in healthy people over age 70, but it is generally confined to an area of the brain called the medial temporal lobe.

The bodies, which were lined up head to feet, were found at the site of an ancient cemetery attached to the Trinity Hospital, which was founded in the 13th century. The burials were discovered during renovations to the basement of the Monoprix Réaumur-Sébastopol supermarket, located in the second-arrondissement neighborhood of Paris. The site was once the location of the Trinity Hospital, which was founded in 1202 by two German noblemen.

It Boils Down to Plumbing  | Geysers erupt — sending steam and hot water hundreds of feet into the air, and often releasing a frightening screech and the stench of rotten eggs — because of a series of loops and side chambers hidden deep below the surface that allows water to boil first at the top and then cascade downward, the study found. Half of them are located in Yellowstone National Park, drawing more than 3 million tourists each year. To better understand the system hidden deep below the surface, Michael Manga, a researcher at the University of California, Berkeley, has spent years studying geysers in Chile and Yellowstone National Park.

The drone was piloted by an employee of the National Geospatial-Intelligence Agency, who decided to test-fly his friend's quadcopter in the early hours of the morning and crashed it, The Washington Post reported. The man was off-duty at the time, and was not involved in any work related to drones, the NGA said in a statement. The high-profile incident exposed a gap in security that the Secret Service has been trying to fix for years, the Post reported. The announcement that drones will fly over D.C. comes just weeks after the government announced a set of rules governing the use of commercial drones in the United States. The Federal Aviation Administration's (FAA) regulations, released Feb. 15, specify that drones up to 55 lbs. (25 kilograms) are permitted to fly at speeds of up to 100 mph (160 km/h) and up to 500 feet (150 meters) in altitude.

"California's warming trend is driving an increase in the risk of drought," said study co-author Daniel Swain, a doctoral student in climate science at Stanford University in California. "Warming in California has made it more probable that when a low precipitation year occurs, it occurs in warm conditions and is more likely to produce severe drought," said lead study author Noah Diffenbaugh, an associate professor in the School of Earth Sciences at Stanford.

The bright-spot mystery is just one question Dawn will tackle after it enters orbit around Ceres at about 7:20 a.m. EST (1220 GMT) on Friday (March 6). "Ceres has really surprised us, and the first images have produced some really puzzling features that have got the team, and I think some other people, really excited," Dawn Deputy Principal Investigator Carol Raymond, of NASA's Jet Propulsion Laboratory in Pasadena, California, said during a news conference Monday (March 2). The two bright spots are close to each other inside a 57-mile-wide (92 kilometers) crater that sits at about 19 degrees north latitude on Ceres, which is the largest object in the main asteroid belt between Mars and Jupiter.

(Reuters) - A U.S. military weather satellite appears to have exploded while in orbit last month after a sudden temperature spike in its power system, producing 43 pieces of new space debris, the Air Force said on Tuesday. The blast, which was first reported by the industry trade publication Space News, was the second Defense Meteorological Satellite Program (DMSP) spacecraft to experience a catastrophic breakup in 11 years. Launched in 1995, the Air Force satellite was serving as an operational spare in the seven-member DMSP network. On Feb. 3, flight controllers observed a sudden temperature spike in the DMSP-F13 satellite's power system and quickly shut down its non-essential systems, but the spacecraft lost the ability to position itself, the Air Force said in a statement.
