A recent study by Swedish researchers found that rheumatoid arthritis (RA) patients did not experience an elevated cancer risk in the first 6 years after starting anti-tumor necrosis factor (TNF) therapy. The research team, led by Johan Askling, M.D., Ph.D., from Karolinska University Hospital in Stockholm, Sweden assessed the short-term and medium-term cancer risk for RA patients using anti-TNF therapies: infliximab, adalimumab, and etanercept.

Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA's orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. The dead-heat finish may stoke the fires of debate among physicists over Einstein's special theory of relativity because one of the photons possessed a million times more energy than the other.
Typhoon Mirinae is moving west and away from the Northern Marianas Islands on a track to a landfall in the Philippines by the weekend. As Mirinae has moved west, NASA's infrared and microwave satellite imagery have seen high, strong thunderstorm development, and a developing eye.
During its first year of operations, NASA's Fermi GammaRay Space Telescope mapped the extreme sky with unprecedentedresolution and sensitivity. It captured more than one thousanddiscrete sources of gamma rays -- the highest-energy form of light.Capping these achievements was a measurement that provided rareexperimental evidence about the very structure of space and time,unified as space-time in Einstein's theories.
Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe -- a gigantic stellar explosion known as a Gamma Ray Burst (GRB).
The explosion was detected on April 23 by NASA's Swift satellite, and scientists soon realized that it was more than 13 billion light-years from Earth. It represents an event that occurred 630 million years after the Big Bang, when the Universe was only four percent of its current age of 13.7 billion years.
JACKSONVILLE, Fla. — High-definition (HD) colonoscopy is much more sensitive than standard colonoscopy in finding polyps that could morph into cancer, say researchers at the Mayo Clinic campus in Florida.
(New York, N.Y. – Oct. 28, 2009) Paved parking lots and driveways make our lives easier, but they often create an easy pathway for pollutants to reach underground water sources and alter the natural flow of water back into the ground. The U.S. Environmental Protection Agency today announced a study that will investigate ways to reduce pollution that can run off paved surfaces and improve how water filters back into the ground. EPA is testing a variety of different permeable pavement materials and rain gardens in the parking lot at the agency's Edison, N.J.
Cobbling together 3000 individual photographs, a physicist has made a new high-resolution panoramic image of the full night sky, with the Milky Way galaxy as its centerpiece. Axel Mellinger, a professor at Central Michigan University, describes the process of making the panorama in the November issue of Publications of the Astronomical Society of the Pacific. An interactive version of the picture can viewed on Mellinger's website: http://home.arcor.de/axel.mellinger/.
Microwave satellite imagery has revealed that Tropical Storm Mirinae is strengthening enough to develop an eye, and that's what it's doing. Mirinae was formerly Tropical Depression 23W, but became a tropical storm and received its name.
Two ingredients that don't mix well with tropical cyclones are waters cooler than 80 degrees Fahrenheit and wind shear. Those two ingredients were added into Tropical Depression Neki's mix late yesterday, and caused Neki to dissipate.
The Geostationary Operational Environmental Satellite called GOES-11 captured a look at Neki's remnants this morning, October 27 at 8 a.m. EDT. Neki appeared as an ill-defined, elongated swirl of low clouds. The Central Pacific Hurricane Center (CPHC) noted that Neki "Appears to be just a surface trough in satellite imagery."
NASA's Aqua and Tropical Rainfall Measuring Mission (TRMM) satellites are watching Tropical Storm Neki become extra-tropical, and TRMM data was used to create a three-dimensional image of the storm.
A 3-D image was created from the TRMM Precipitation Radar (PR) instrument on the satellite. It showed Neki still had a small area where potent thunderstorms reached to heights of about 16 kilometers (~52,493 feet) early this morning, October 26.
LOS ALAMOS, New Mexico, October 26, 2009— Understanding dark energy is the number one issue in explaining the universe, according to Salman Habib, of the Laboratory's Nuclear and Particle Physics, Astrophysics and Cosmology group.
San Diego, CA (October 26, 2009) – In two new studies, presented at the American College of Gastroenterology's (ACG) 74th Annual Scientific meeting in San Diego, researchers explored the connection between high stress, high exposure occupations and long-term gastrointestinal disorders.
San Diego, CA (October 26, 2009) – Findings from a new retrospective cohort study presented at the American College of Gastroenterology's 74th Annual Scientific meeting in San Diego indicate that patients with Inflammatory Bowel Disease (IBD), especially those receiving the thiopurine class of medications to treat IBD, may be at risk for developing non-melanoma skin cancer (NMSC).
San Diego, CA (October 26, 2009) – Helicobater pylori, a bacteria implicated in peptic ulcers and gastritis, was eradicated in 95 percent patients who took a 7-day course of combination therapy with levofloxacin, omeprazole, nitazoxanide (Alinia®) and doxycycline (LOAD) compared to eradication in only 80.9 percent of patients on lansoprazole, amoxicillin and clarithromycin (LAC) for seven days.
