We all want that summer glow that comes from a day at the beach, but taking in the rays can have long-term implications for our health. Now Dr. Niva Shapira of Tel Aviv University's School of Health Professions suggests a way to make fun in the sun safer ― and it's all in our food.
Since its October 2008 launch, NASA's Interstellar Boundary Explorer (IBEX) spacecraft has mapped the invisible interactions occurring at the edge of the solar system, surpassing its mission objectives with images that reveal the interactions between our home in the galaxy and interstellar space to be surprisingly structured and intense.
Less than two years later, its science program has also flourished into multiple research studies extending way beyond the original scope of the mission.
A study by Kristin Jordan, a doctoral student in Indiana University Bloomington's Department of Sociology, found that students with low-income or minority status do not prepare for college in the same way as their more privileged counterparts, regardless of their academic ability or plans to attend college. The less privileged students are over-represented in community colleges while their counterparts are more likely to attend more selected schools.
A surgery developed at Hospital for Special Surgery can improve patient outcomes in individuals with severe adult flat foot deformity, a problem that is increasingly being seen inhospitals across the country. Patients who undergo the new surgery have better long-term outcome and mobility than those who undergo traditional surgery. The paper will be presented at the annual meeting of the American Orthopaedic Foot and Ankle Society (AOFAS, abstract 348) in National Harbor, Md., on July 8.
System 96L looks like an oval-shaped area of clouds in a recent visible satellite image from the GOES-13 satellite. The National Hurricane Center noted that it now has a 50% chance of development into a tropical depression by sometime on Thursday.
Within the human digestive tract is a teeming mass of hundreds of types of bacteria, a potpourri of microbes numbering in the trillions that help us digest food and keep bad bacteria in check.
Now scientists have found that the vitamin D receptor is a key player amid the gut bacteria – what scientists refer to matter-of-factly as the "gut flora" – helping to govern their activity, responding to their cues, and sometimes countering their presence. The work was published online recently in the American Journal of Pathology.
Combining observations made with ESO's Very Large Telescope and NASA's Chandra X-ray telescope, astronomers have uncovered the most powerful pair of jets ever seen from a stellar black hole. This object, also known as a microquasar, blows a huge bubble of hot gas, 1000 light-years across, twice as large and tens of times more powerful than other known microquasars. The discovery is reported this week in the journal Nature.
Obstructed defecation syndrome (ODS ) represents a widespread clinical problem which frequently affects middle-aged females. Nevertheless, many of the previously established techniques are unsuitable for patients with ODS associated with simultaneous rectocele and rectal intussusception. Notably, STARR has been proposed as an alternative operation and a relatively noninvasive surgical technique for this difficult problem. However, some serious complications were documented and there is limited evidence attest to the safety and long-term efficacy of the STARR procedure.
ESA's Planck mission has delivered its first all-sky image. It not only provides new insight into the way stars and galaxies form but also tells us how the Universe itself came to life after the Big Bang.
Tropical Depression Alex dissipated over the mountains of central Mexico, but his rainy remnants have moved into south, central and western Texas. The GOES-13 satellite is keeping an eye on Alex's remnants as they have prompted flash flood watches in those areas today.
Areas of northeastern Mexico were slammed with heavy rainfall, and NASA's Tropical Rainfall Measuring Mission Satellite estimated more than 10 inches of rainfall fell in various locations and that data was used to create a rainfall map.
Washington, D.C.—Up to now scientists thought that the trace amounts of carbon on the surface of the Moon came from the solar wind. Now researchers at the Carnegie Institution's Geophysical Laboratory have detected and dated Moon carbon in the form of graphite—the sooty stuff of pencil lead—which survived from the late heavy bombardment era 3.8 billion years ago. The researchers found instances of graphite and a form of rolled graphite called graphite whiskers that could only form in very high temperature reactions initiated by an impact.
Alex made landfall at 10 p.m. EDT in northeastern Mexico, about 110 miles south of Brownsville, Texas. By 8 a.m. EDT on July 1, Alex has weakened to a tropical storm and GOES satellite imagery showed it moving near the high mountains of Mexico.
