Small hairy balls hide foul-tasting healthful enzymes (November 28, 2009) -- A Dutch researcher has discovered a new way to package enzymes by causing charged polymers to form a 'ball of hair' around them. Her approach significantly increases the utility of the enzymes. For example, healthy enzymes with a foul taste can be packaged in such a way that they are released in the stomach without being tasted. ... > full story
Volunteers wanted for simulated 520-day Mars mission (November 28, 2009) -- Starting in 2010, an international crew of six will simulate a 520-day round-trip to Mars, including a 30-day stay on the martian surface. In reality, they will live and work in a sealed facility in Moscow, Russia, to investigate the psychological and medical aspects of a long-duration space mission. ESA is looking for European volunteers to take part. ... > full story
With first neutrino events, physicists closer to answering why only matter in universe (November 27, 2009) -- Physicists have just announced that they have detected the first neutrino events generated by the newly built neutrino beam at the J-PARC accelerator laboratory in Tokai, Japan. Neutrino oscillations, which require neutrinos to have mass and therefore were not allowed in previous theoretical understanding of particle physics, probe new physical laws and are of great interest in the study of the fundamental constituents of matter. ... > full story
Nano-scale drug delivery developed for chemotherapy (November 27, 2009) -- Bioengineers have developed a simple and inexpensive method for loading cancer drug payloads into nano-scale delivery vehicles and demonstrated in animal models that this new nanoformulation can eliminate tumors after a single treatment. ... > full story
Plasma-in-a-bag for sterilizing devices (November 27, 2009) -- The practice of sterilizing medical tools and devices helped revolutionize health care in the 19th century because it dramatically reduced infections associated with surgery. Through the years, numerous ways of sterilization techniques have been developed, but the old mainstay remains a 130-year-old device called an autoclave, which is something like a pressure steamer. Now researchers in the Netherlands are developing a new way to sterilize medical devices by sealing them inside plastic bags and then using electromagnetic fields to create plasmas -- partially ionized gasses that contain free electrons and reactive ions. ... > full story
Building real security with virtual worlds (November 27, 2009) -- Advances in computerized modeling and prediction of group behavior, together with improvements in video game graphics, are making possible virtual worlds in which defense analysts can explore and predict results of possible military and policy actions, say computer science researchers. ... > full story
3-D software gives doctors, students a view inside the body (November 27, 2009) -- Researchers have developed technology that turns flat medical scans into vibrant 3-D images that can be shifted, adjusted, zoomed and replayed at will. ... > full story
Research sheds light on workings of anti-cancer drug (November 27, 2009) -- The copper sequestering drug tetrathiomolybdate (TM) has been shown in studies to be effective in the treatment of Wilson disease, a disease caused by an overload of copper, and certain metastatic cancers. That much is known. Very little, however, is known about how the drug works at the molecular level. A new study now has provided an invaluable clue: the three-dimensional structure of TM bound to copper-loaded metallochaperones. ... > full story
New computer virus disguised as social security administration download (November 27, 2009) -- A new spam campaign using false e-mails made to look like messages from the Social Security Administration is capable of stealing Social Security numbers and downloading malware onto victims' home computers, says a computer forensics expert. ... > full story
Overcoming barriers for organic electronics (November 27, 2009) -- Electronic devices can't work well unless all of the transistors, or switches, within them allow electrical current to flow easily when they are turned on. Engineers have now determined why some transistors made of organic crystals don't perform well, yielding ideas about how to make them work better. ... > full story
New tool for helping pediatric heart surgery (November 27, 2009) -- A team of researchers has developed a way to simulate blood flow on the computer to optimize surgical designs. It is the basis of a new tool that may help surgeons plan for a life-saving operation called the "Fontan" surgery, which is performed on babies born with severe congenital heart defects. ... > full story
RFID Chips: Intelligence inside metal components (November 27, 2009) -- Up to now, extreme production temperatures made it impossible to equip metallic components with RFID chips during the operating process. Researchers present a variation on a process that makes the non-destructive integration of radio chips a reality. ... > full story
