When targeting spiral galaxy bulges, astronomers often seek edge-on galaxies, as their bulges are more easily distinguishable from the disc. This exceptionally detailed edge-on view of NGC 4710 taken by the Advanced Camera for Surveys (ACS) aboard Hubble reveals the galaxy's bulge in the brightly coloured centre. The luminous, elongated white plane that runs through the bulge is the galaxy disc. The disc and bulge are surrounded by eerie-looking dust lanes.

This morning, Cyclone Anja was a powerful Category 4 cyclone on the Saffir-Simpson scale. Wind shear has now giving Anja a strong "punch in the gut" as the storm has weakened to a Category 1 cyclone.

A new study finds that a species of sea star stays cool using a strategy never before seen in the animal kingdom. The sea stars soak up cold sea water into their bodies during high tide as buffer against potentially damaging temperatures brought about by direct sunlight at low tide.

"Sea stars were assumed to be at the mercy of the sun during low tide," said the study's lead author, Sylvain Pincebourde of François Rabelais University in Tours, France. "This work shows that some sea stars have an unexpected back-up strategy."

"One of the major problems in modern astrophysics is the fact that we still do not know exactly what kinds of stellar system explode as a Type Ia supernova," says Patrick Woudt, from the University of Cape Town and lead author of the paper reporting the results. "As these supernovae play a crucial role in showing that the Universe's expansion is currently accelerating, pushed by a mysterious dark energy, it is rather embarrassing."

Department of Astronomy, Nanjing University in Nanjing, China – Solar coronal seismology based on magnetic field-line stretching model of "EIT waves" is proposed, which is demonstrated to be potentially able to probe the mysterious magnetic field in the solar corona.

The study, which was led by Dr. Chen, is reported in Issue 52 of Science in China (G) because of its significant research value.

Daily text-message reminders appear to increase sunscreen use over a six-week period, according to a report in the November issue of Archives of Dermatology, one of the JAMA/Archives journals.

Skin cancer accounts for one in three cancer cases worldwide and more than 1 million new cases are diagnosed in the United States each year, according to background information in the article. "Many of these cases could be prevented if the population took consistent measures to avoid direct sunlight by wearing protective clothing and applying sunscreen," according to the study.

The recent failure of an HIV vaccine was probably caused by the immune system reacting to the virus 'shell' used to transmit the therapy around the body, according to research published today (16 November 2009) in the Proceedings of the National Academy of Sciences.

The trial, called 'STEP', was halted in September 2007 because preliminary results suggested that people who had been given the vaccine were more likely to be infected with HIV than people who had been given a placebo.

WHAT:A new study shows that molecular similarities exist between the 2009 H1N1 influenza virus and other strains of seasonal H1N1 virus that have been circulating in the population since 1988. These results suggest that healthy adults may have a level of protective immune memory that can blunt the severity of infection caused by the 2009 H1N1 influenza virus.

NASA's Terra satellite captured a stunning image of Anja, the first tropical cyclone of the southern Hemisphere cyclone season. When Anja formed on Saturday, November 14, in the Southern Indian Ocean, about 330 miles south-southwest of Diego Garcia it was designated Tropical Cyclone 01S ("S" for south). By Sunday, November 15, 01S had strengthened into a tropical storm and was named Anja.

"Source I is the richest source of masers in the Galaxy, that we know of," said Lynn Matthews, lead author of the new work, who is now a researcher at the MIT Haystack Observatory. "Without the masers, we couldn't track the gas motions in such detail so close to this massive star, and would be relatively blind to its formation."

"In astronomy, it's rare to see changes over the course of a human lifetime. With this new movie, we can see changes over just a few months as gas clumps swarm around this young protostar," added Smithsonian astronomer and co-author Ciriaco Goddi.

GREENBELT, Md. -- In a partnership that exemplifies One NASA, engineers at NASA's Goddard Space Flight Center in Greenbelt, Md. teamed up with engineers at NASA's Johnson and Kennedy Space Centers to design, build, and test five new ExPRESS Logistics Carriers, or ELCs, which will be delivered to the International Space Station. "ExPRESS" stands for Expedite the Processing of Experiments to the Space Station.

Cyclone Phyan broke a 43 year record when it made landfall north of the city of Mumbai, India during the evening hours on November 11. NASA's Aqua satellite captured Phyan's landfall with one instrument, and a day later, another of Aqua's instruments show the storm's remnants raining Tibet as Phyan continues to dissipate.

Some of Rosetta's instruments have been on since early November, performing imaging, magnetospheric, and atmospheric observations, as well as looking for water on the Moon. The first round of images and data recorded just before and during the swingby will be downloaded later today.

The coastal low, formerly known as Ida, is currently quasi-stationary off the North Carolina coast, adding more rain on top of what it has already brought. The low is creating serious flooding from northeast North Carolina to coastal Virginia.

A retired employee of NASA's Wallops Flight Facility provided photographs of flooded roadways in Accomack County, Virginia, and reported trees down and other damages this afternoon.

PHILADELPHIA – November 12, 2009 – Shire plc (LSE: SHP, NASDAQ: SHPGY), the global specialty biopharmaceutical company, announced findings from a post hoc analysis examining emotional lability from Phase 3 study data with Vyvanse®. In this study, Vyvanse demonstrated significant improvement in Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms as measured by the ADHD Rating Scale IV (ADHD-RS IV) and Connors' Parent Rating Scale-Revised Short (CPRS-RS) in children with ADHD aged 6 to 12 years.
