Solar wind generated by the sun is probably driven by a process involving powerful magnetic fields, according to a new study led by UCL (University College London) researchers based on the latest observations from the Hinode satellite.

Magnetized plasmas occupy a large fraction of our cosmic universe; they exist on our sun, in the earth's magnetosphere, and in astrophysical plasmas. They also exist in laboratory magnetic fusion grade plasmas, and in other smaller experiments as well. Energy stored in stressed magnetic fields can produce large-scale explosive events that spontaneously evolve and energize particles, owing to unsteady and impulsive local processes in small volumes of space. The abrupt onset and cessation of these events in astrophysical and laboratory plasmas is a long-standing puzzle.
DETROIT – Extending hepatitis C treatment for liver transplant patients beyond current practice results in high rates of clearance of the hepatitis C virus from the blood, as well as a low rate of relapse, according to a Henry Ford Hospital study.
"We found that patients who achieved a sustained virological response were more likely to have had extended treatment," says Kimberly Brown, M.D., Division head of Gastroenterology at Henry Ford Hospital and senior author of the study.
DETROIT – A Henry Ford Hospital study found that hepatitis B does not increase the risk for pancreatic cancer – and that only age is a contributing factor.
The results contradict a previous study in 2008 that suggested a link between pancreatic cancer and previous hepatitis B infection. Hepatitis B is an inflammation of the liver caused by a viral infection.
Study results will be presented at the American Association for the Study of Liver Diseases' Annual Meeting in Boston.
On August 1, 2008 a total solar eclipse was visible within a narrow corridor that traversed from North America to China. The path of the Moon's umbral shadow started from Canada and extended across northern Greenland, the Arctic, central Russia, Mongolia, and China. A partial eclipse was seen within the much broader path of the Moon's penumbral shadow, which included northeastern part of North America, most parts of Europe and Asia.
If you're sick, traveling to a foreign land may boost your spirits, but jeopardize your health, according to a paper being presented at the American Society of Nephrology's 42nd Annual Meeting and Scientific Exposition in San Diego, CA. The findings indicate that dialysis patients who travel on vacation risk infections, anemia, and other complications that can compromise their dialysis treatments.
BUFFALO, N.Y. -- While detailed contracts can foster trust between parties, there needs to be flexibility in negotiating potential changes, according to research recently published in MIS Quarterly.
When 100 m sprinters launches themselves from the starting blocks, the race can be won or lost in the first few strides. Acceleration through the first few strides is the key to winning gold.
The proposed Medicare "bundled" payment system for dialysis is likely to reduce government reimbursements for dialysis units in certain regions of the United States and for some types of facilities, according to research being presented at the American Society of Nephrology's 42nd Annual Meeting and Scientific Exposition in San Diego, CA.
HONOLULU – October 29, 2009 – Shire plc (LSE: SHP, NASDAQ: SHPGY), the global specialty biopharmaceutical company, announced today that it will present key scientific data on its Attention-Deficit/Hyperactivity Disorder (ADHD) treatments, INTUNIV™ (guanfacine) Extended Release Tablets, Vyvanse® (lisdexamfetamine dimesylate) Capsules CII, and Daytrana® (methylphenidate transdermal system) CII, at a national meeting of psychiatrists to be held October 27 - November 1 in Honolulu.
Another typhoon in the northern Philippines really is something to be scared about, and Mirinae is expected to make landfall there in the mid-morning hours on Halloween, October 31. Mirinae will be the fourth major storm to hit the Philippines in one month bringing more rain to an already flood-weary region.
NASA's Tropical Rainfall Measuring Mission (TRMM) satellite is already hard at work analyzing rainfall, to provide meteorologists with an idea of what can be expected when the storm hits.
FLAGSTAFF, Ariz. – Oct. 29, 2009 – The Phoenix-based non-profit Translational Genomics Research Institute (TGen) announced today that, along with a business collaborator, it will submit a request to the U.S. Food and Drug Administration for emergency use of a new test to diagnose the 2009 H1N1 swine flu virus.
Details about TGen's test will be presented Sunday (Nov. 1) at the 47th annual meeting of the Infectious Diseases Society of America (IDSA), being held today through Sunday (Oct. 29-Nov. 1) in Philadelphia.

Many of us have been rescued from unfamiliar territory by directions from a Global Positioning System (GPS) navigator. GPS satellites send signals to a receiver in your GPS navigator, which calculates your position based on the location of the satellites and your distance from them. The distance is determined by how long it took the signals from various satellites to reach your receiver.
The system works well, and millions rely on it every day, but what tells the GPS satellites where they are in the first place?
Star clusters are among the most visually alluring and astrophysically fascinating objects in the sky. One of the most spectacular nestles deep in the southern skies near the Southern Cross in the constellation of Crux.
The Kappa Crucis Cluster, also known as NGC 4755 or simply the "Jewel Box" is just bright enough to be seen with the unaided eye. It was given its nickname by the English astronomer John Herschel in the 1830s because the striking colour contrasts of its pale blue and orange stars seen through a telescope reminded Herschel of a piece of exotic jewellery.
