Washington, DC – Preliminary findings from a unique study with sunitinib suggest that it might be possible to tweak the dosage of chemotherapy drugs used to treat HIV-positive cancer patients to achieve therapeutic benefit. Given the type of drug cocktail patients use to treat their HIV, much more or considerably less chemotherapy may be warranted, say the researchers, part of the NCI-supported AIDS Malignancy Consortium (AMC). The trial design is being presented at the 2010 annual meeting of the American Society of Clinical Oncology (ASCO).

Tropical Cyclone Phet made landfall in Oman on June 3 and is now back in the Arabian Sea and headed toward a second landfall in Pakistan this weekend. NASA's Aqua and Terra satellites have captured infrared and visible views of the storm.
Researchers say they have discovered that methane-eating bacteria survive in a highly unique spring located on Axel Heiberg Island in Canada's extreme North.
OAK BROOK, Ill. – June 3, 2010 – The American Society for Gastrointestinal Endoscopy (ASGE) has issued guidelines addressing ethnicity, gastrointestinal diseases and endoscopic procedures. The guideline suggests that colorectal cancer screening should begin at age 45 for average risk African-American men and women, and that it is recommended that colorectal cancer screening be emphasized for other minority ethnic groups that have lower screening utilization rates.
Joint source-channel coding/decoding (JSCC/JSCD) techniques have become state-of-the-art and one of the challenging research subjects in the spatial communication area. This paper addresses the basic principles of joint source-channel optimal design and classification of various existing JSCC/JSCD methods. It presents a JSCD scheme based on variable-length coding, which is capable of providing reliable resolutions and has shown superior performance compared with the existing ones.
TEMPE, Ariz. – It's amazing what cleaning your glasses can reveal. A mineral-scouting instrument developed at Arizona State University has found an outcrop of rock rich in carbonates in the Columbia Hills of Gusev Crater on Mars, according to a report published online June 3 in the journal Science. The instrument is onboard NASA's Mars Exploration Rover Spirit.
A new study shows a thick organic haze that enshrouded early Earth several billion years ago may have been similar to the haze now hovering above Saturn's largest moon, Titan, and would have protected primordial life on the planet from the damaging effects of ultraviolet radiation.
Children with autism have a different chemical fingerprint in their urine than non-autistic children, according to new research published tomorrow in the print edition of the Journal of Proteome Research.
The researchers behind the study, from Imperial College London and the University of South Australia, suggest that their findings could ultimately lead to a simple urine test to determine whether or not a young child has autism.
DETROIT – The size of tumors in prostate cancer patients is directly linked to their weight, according to a new six-year study conducted by researchers at Henry Ford Hospital in Detroit.
The research team, led by Nilesh Patil, M.D., of Henry Ford's Vattikuti Urology Institute and Department of Radiology, found heavier patients, or those with the highest body mass index (BMI), also had the largest tumors. They discovered the connection after studying 3,327 patients who had undergone robotic removal of their cancerous prostate glands and surrounding tissue.
When loaded with an anticancer drug, a delivery system based on a novel material called nanosponge is three to five times more effective at reducing tumor growth than direct injection.
That is the conclusion of a paper published in the June 1 issue of the journal Cancer Research.
With a mass of more than 10 000 suns packed into a volume with a diameter of a mere three light-years, the massive young star cluster in the nebula NGC 3603 is one of the most compact stellar clusters in the Milky Way [1] and an ideal place to test theories for their formation.
Spanish sign language is used by over 100,000 people with hearing impairments and is made up of hundreds of signs. CVC-UAB researchers Sergio Escalera, Petia Radeva and Jordi Vitrià selected over twenty of these signs to develop a new visual interpretation system which allows deaf people to carry out consultations in the language they commonly use.
A development model of the Mars Rover, called Bridget, was on display at the University today- Friday June 4- providing invited schoolchildren as well as staff and students with an exciting glimpse into the shape of things to come.
The event coincides with celebrations marking the 50th anniversary of space research at the University of Leicester.
