The frozen cap of the Arctic Ocean appears to have reached its annual summertime minimum extent and broken a new record low on Sept. 16, the National Snow and Ice Data Center (NSIDC) has reported. Analysis of satellite data by NASA and the NASA-supported NSIDC at the University of Colorado in Boulder showed that the sea ice extent shrunk to 1.32 million square miles (3.41 million square kilometers).

Pasadena, CA— With the combined power of NASA's Spitzer and Hubble Space Telescopes, as well as a cosmic magnification effect, a team of astronomers, including Carnegie's Daniel Kelson, have spotted what could be the most distant galaxy ever seen. Light from the young galaxy captured by the orbiting observatories was emitted when our 13.7-billion-year-old universe was just 500 million years old. Their work is published September 20 by Nature.

Northwestern University scientists have developed a thermoelectric material that is the best in the world at converting waste heat to electricity. This is very good news once you realize nearly two-thirds of energy input is lost as waste heat.
The material could signify a paradigm shift. The inefficiency of current thermoelectric materials has limited their commercial use. Now, with a very environmentally stable material that is expected to convert 15 to 20 percent of waste heat to useful electricity, thermoelectrics could see more widespread adoption by industry.
Former Hurricane Lane has fizzled and its remnant circulation was spotted in a blanket of low clouds in the Eastern Pacific Ocean.
BOULDER--For airline passengers who dread bumpy rides to mountainous destinations, help may be on the way. A new turbulence avoidance system has for the first time been approved for use at a U.S. airport and can be adapted for additional airports in rugged settings across the United States and overseas.
Type 1 diabetes is the autoimmune form of diabetes, in which the patients' insulin-producing beta cells are destroyed by their own immune system.
"We know that if a person has two autoantibodies and one of them is against insulin, there is a 50 per cent risk that they will develop type 1 diabetes within five years. It doesn't matter how old you are", says Åke Lernmark, Professor of Experimental Diabetes Research at Lund University in Sweden.
NOAA's GOES-13 satellite sits in a fixed position over the eastern U.S. that allows it to monitor the Atlantic Ocean and it captured a visible image of Tropical Storm Nadine on Sept. 18, 2012 at 10:45 a.m. EDT when it was nearing the Azores. Satellite imagery shows that the strongest convection (rising air that forms the thunderstorms that make up the tropical cyclone) is located north of the center of circulation. NOAA manages the GOES series of satellites, and NASA's GOES Project at the NASA Goddard Space Flight Center in Greenbelt, Md.
Powerful thunderstorms wrapped tightly around Hurricane Lane's center as it continued moving through the eastern Pacific Ocean. When NASA's Terra satellite passed over Lane it captured a close-up view of the storm and noticed that Lane's eye had become cloud-filled as if being punched in the eye. Nature is expected to fight Lane more and win over the next couple of days.
Heavy rainfall from Typhoon Sanba caused flooding, landslides and at least one death when it hit South Korea on Monday September 17, 2012. NASA's TRMM satellite captured rainfall and thunderstorm cloud height data as Sanba drenched southwestern Japan earlier, and its eye passed to the west of the Japanese island of Kyushu.
Bethesda, MD – A new report from the Office of Management and Budget (OMB) is a stark reminder of the perilous situation facing the medical research and scientific communities unless Congress and the President take action to prevent the pending sequestration. Set in motion by the Budget Control Act of 2011, sequestration would impose automatic cuts on federal funding starting on January 2, 2013.
COLUMBUS, Ohio - More than one-third of young adults who reported being victims of dating violence as teenagers had two or more abusive partners, a new study suggests.
The study involved 271 college students who recalled dating violence - including physical, sexual and psychological abuse - from ages 13 to 19.
Overall, nearly two-thirds of both men and women reported some type of abuse during their teenage years, which falls in line with other studies.
On Earth the atmosphere and the magnetic field weaken cosmic rays. But on Moon and Mars they pelt down unhamperdly. The cosmic radiation can harm astronauts and could cause cancer in the long run as a result of damage in DNA and cells.
Scientists can't travel deep space the way Columbus sailed and charted the New World or Lewis and Clark mapped the west. But, researchers at Case Western Reserve University and two partnering institutions have found a possible way to map the spread and structure of the universe, guided by the light of quasars.
The technique, combined with the expected discovery of millions more far-away quasars over the next decade, could yield an unprecedented look back to a time shortly after the Big Bang, when the universe was a fraction the size it is today.
Over the next few weeks, an ER-2 high altitude research aircraft operating out of NASA's Wallops Flight Facility in Wallops Island, Va., will take part in the development of two future satellite instruments. The aircraft will fly test models of these instruments at altitudes greater than 60,000 feet to gather information researchers can use to develop ways to handle data future spaceborne versions will collect.
