Space & Earth news
Bin in Hawaii confirmed to be Japan tsunami debris

After victory lap, Endeavor rolls to retirement
(AP)—Space shuttle Endeavour rocketed beyond Earth orbit 25 times. Its 26th mission: a 12-mile (19-kilometer) commute through the streets of Los Angeles to its new retirement home in a museum.
New NASA photo satellite to join 40-year mission
A fleet of picture-snapping NASA satellites that for 40 years has documented forest fires, tsunamis and everyday changes in the Earth's geography will soon get a new member.
Spaceport is built, but who will come?
New Mexico Tourism Secretary Monique Jacobson says it will be New Mexico's Sydney Opera House. Virgin Galactic Chairman Richard Branson has hinted it will host the first of his new brand of lifestyle hotels. And the eclectic hot springs town of Truth or Consequences has been anxiously awaiting all the economic development the nearly quarter-of-a-billion-dollar project is supposed to bring to this largely rural part of southern New Mexico.
Constraining world trade is unlikely to help the climate, study says
From rubber dinghies to television sets: the emissions of greenhouse gases in countries like China are to a significant extent caused by the production of goods that are exported to Germany or the United States. But this doesn't necessarily mean that Western countries have relocated their emission-intensive industries and hence escape regulation for climate protection. This is shown in a study appearing in Nature Climate Change this week.
North Atlantic 'Achilles heel' lets upper atmosphere affect the abyss
A University of Utah study suggests something amazing: Periodic changes in winds 15 to 30 miles high in the stratosphere influence the seas by striking a vulnerable "Achilles heel" in the North Atlantic and changing mile-deep ocean circulation patterns, which in turn affect Earth's climate.

GM offers big discounts to boost Volt sales (Update)
General Motors rolled out the Chevrolet Volt two years ago with lofty sales goals and the promise of a new technology that someday would help end America's dependence on oil.
Hydrogen fuel cell for phone charging set for 2013
(Phys.org)—A three-way collaboration between Japan-based Rohm, Aquafairy, and Kyoto University has resulted in the development of a smartphone-charging fuel cell—a compact, high output, portable hydrogen powered fuel cell that can generate electricity by producing hydrogen. This is achieved through a chemical reaction between calcium hydride sheets and water. The fuel cell can generate five watt hours of electricity, to charge an average smartphone within two hours. The fuel cell will be promoted for a variety of uses, from charging a smartphone to serving as a 200-watt portable generator delivering backup power.
Not fare: Hacker app resets subway card for free rides (w/ Video)
(Phys.org)—You have to love the ease and convenience of NFC technology in smartphones. Unless you run a mass transit system in a major city that moves millions of people in and out of trains, morning noon and night, then love alone is not enough. As fares form a crucial part of transit system revenue to keep everything running, system administrators would need to take note of what security hackers accomplished—an app that takes advantage of a weakness in NFC-based subway cards that lets users ride on trains for free. The two researchers, Corey Benninger and Max Sobell, from the Intrepidus Group, figured out a way that replenishes a fare-card balance.

Simple ovarian cancer symptom survey that checks for six warning signs may improve early detection
A simple three-question paper-and-pencil survey, given to women in the doctor's office in less than two minutes, can effectively identify those who are experiencing symptoms that may indicate ovarian cancer, according to a study by researchers at Fred Hutchinson Cancer Research Center. The study represents the first evaluation of an ovarian cancer symptom-screening tool in a primary care setting among normal-risk women as part of their routine medical-history assessment. The results are published online in the Open Journal of Obstetrics and Gynecology.
IV acetaminophen eases post-spinal op pain for children
(HealthDay)—Children and adolescents given intravenously (IV)-administered acetaminophen after major spine surgery have significantly less postoperative pain, compared with those given placebo, but administration of acetaminophen does not reduce the need for opioids, according to a study published in the Sept. 15 issue of Spine.

Solving puzzle of B-cell lymphoma development
Germinal centers are sites in the organs of the lymphatic system, formed during the course of an immune response to infection, where B cells intensely proliferate and modify their DNA in order to produce antibodies specific for the pathogen. However, it is known that the vast majority of lymphomas derive from the B cells at the germinal centers.
Researchers develop editing toolkit for customizing zebrafish genomes

One subtype of breast cancer shares many genetic features with high-grade serous ovarian cancer, a cancer that is very difficult to treat, according to researchers supported by the National Institutes of Health. The findings suggest that the two cancers are of similar molecular origin, which may facilitate the comparison of therapeutic data for subtypes of breast and ovarian cancers.
