A commercial space company has revealed the design of the lunar lander that it aims to send to the moon in 2015. California-based Moon ExpressÂ unveiled the blueprint and firstÂ images of its MX-1 lunar landerÂ today (Dec. 5) in Las Vegas, during the last day of the Autodesk University computer-aided design conference. In addition to delivering payloads to the lunar surface, the coffee-table-size MX-1 could also help service satellites, deploy tiny "cubesats" in Earth orbit and clean up space junk, company officials say. "We really have tried to create a multifaceted, flexible and scalable spacecraft that can be utilized by other people for a number of different business applications," Moon Express co-founder and CEO Bob Richards told SPACE.com.
This cycle of motion is altogether known as convection, and zones where it takes place are known as convection cells. The rotation of the sun on its axis causes the largest convection cells to form circular, spiraling patterns. "These are a lot like weather patterns seen on Earth â vortices that spiral and turn all over the place," study author Lisa Upton, a solar scientist at Vanderbilt University in Nashville, told SPACE.com. the rotation of the Earth then makes convecting air on Earth spiral.
Nelson Mandela will be remembered as a beloved leader, a moral authority and an extraordinary human being. Imprisoned for 27 years for opposing the racist institution of apartheid, Mandela later became the first black president of South Africa, where he brought about a peaceful transition from the white-dominated government to a multiracial democracy. "He stood for something very simple, which was for equality and fairness," said David James Smith, author of the biography "Young Mandela: The Revolutionary Years" (Little, Brown and Company, 2010). Mandela became a symbol of the struggle against apartheid in South Africa, Smith told LiveScience.
A group of pilot whales that wandered into a remote part of Everglades National Park in South Florida is now heading back toward the sea, according to government officials. Yesterday (Dec. 4), a group of 41 whales was found close to shore, in water as shallow as 3 feet (1 meter), which is dangerous for them â they are typically found in much deeper waters, said Blair Mase, a marine mammal specialist with the National Oceanic and Atmospheric Administration (NOAA) Fisheries service. A total of 10 of the pilot whales were reported dead yesterday, and that number has now climbed to 11, Mase said today during a telephone news conference. Today, crews from NOAA and the National Park Service helped guide the whales toward the sea by placing their crafts between the shore and the whales.
People who eat a very healthy diet, like one rich in fruits, vegetables, nuts and fish, end up spending about $1.50 more per day, on average, than those who eat a less healthy diet, like one focused on processed foods, meats and refined grains, the study found. That adds up to about $550 extra dollars yearly for those who eat healthy, a cost that could represent a real burden for some families, said study researcher Dr. Dariush Mozaffarian, an associate professor at Harvard School of Public Health. People often say that healthy diets are more expensive, but "until now, the scientific evidence for this idea has not been systematically evaluated, nor have the actual differences in cost been characterized," said study researcher Mayuree Rao, also of Harvard.
More than 15,000 Americans suffered decoration-related injuries during the 2012 holiday season, from ladder spills to back strains, according to a new estimate from the U.S. Consumer Product Safety Commission. That figure marks an increase from the previous year, the CPSC reported,Â and in fact, holiday decorating injuries have climbed steadily since 2009, when there were about 12,000 such incidents. CPSC acting chairman Robert Adler had a few key recommendations to avoid decorating disasters: "Keep Christmas trees watered well, don't leave candles unattended, and use caution whenever you are on a ladder." According to the CPSC, these fires resulted in 10 deaths, 20 injuries and $16 million in damage.
It lies within a region called the anterior midcingulate cortex, which is known to be broadly involved in emotion, pain and decision-making â particularly goal-oriented decisions â although the specifics of how it works remain unclear. Now, researchers at Stanford University have found this area of the brain seems to play an important role in what researchers call a person's "willingness to persevere," which means striving toward a goal despite serious problems. "It wasn't that we started out looking for this, it just so happened that both of these patients had a similar reaction," study co-author Vinitha Rangarajan told LiveScience. When the researchers inserted electrode probes into the anterior midcingulate cortex of each patient, and stimulated this region of their brains, the electric charge did not produce seizures â indicating that this region was healthy in both individuals.
The U.S. Air Force's mysterious X-37B space plane is nearing a major milestone â one year of travel in Earth orbit, performing duties in support of long-term space objectives. The unmanned X-37B spacecraft â flying a mission known as Orbital Test Vehicle 3 (OTV-3) â launched into space atop an Atlas 5 rocket from Floridaâs Cape Canaveral Air Force Station on Dec. 11, 2012. What payloads the space plane is toting and the overall mission goals on its confidential cruise are classified. That OTV-1 mission lasted nearly 225 days in orbit, gliding back to Earth on autopilot over the Pacific Ocean and touching down at Vandenberg Air Force Base in California.
A NASA probe has captured an amazing video of the huge and mysterious six-sided vortex spinning around Saturn's north pole. Scientists created the new video of Saturn's vortex from 128 images snapped by NASA's Cassini spacecraft in December 2012. "The hexagon is just a current of air, and weather features out there that share similarities to this are notoriously turbulent and unstable," Andrew Ingersoll, a Cassini imaging team member at the California Institute of Technology in Pasadena, said in a statement. The hexagonal vortex was discovered by NASA's Voyager mission in the early 1980s, and Cassini has gotten some good looks at the feature since August 2009, when sunlight began flooding Saturn's northern hemisphere at the start of the planet's northern spring.
Now, new research in mice reveals how experience can be passed down through generations due to changes in DNA. Scientists trained mice to associate the scent of cherry blossoms with the fear of receiving an electric shock, and found that the mice's pups and grandpups were more sensitive to the scent, even though they didn't receive the shock training. The mice appear to have inherited the fear knowledge through modifications to their genetic code.
