Bacterial response to oxidation studied as toxin barometer
...been assisting with the research teams attempts to immobilize the sentinel bacteria as part of a biosensor design strategy. Nancy Love (www.cee.vt.edu/people/love.html) began her work with microbes by finding organisms that could be used to digest waste in wastewater treatment plants. When she noticed that ...Microscopic sea creatures provide foundation for gas sensors and other devices
...ut 10 micrometers in length, could also be used to immobilize enzymes for purifying drugs in high-performance liquid chromatography (HPLC) and as improved electrodes in lithium-ion batteries. "Silicon can form compounds that have a high lithium content," Sandhage said. "Because diatom-derived silicon structu...Chimpanzees found to use tools to hunt mammalian prey
...ggesting that the jabbing actions were intended to immobilize bushbabies, rather than rouse them from their cavities (bushbabies move quickly and might otherwise easily evade chimpanzees once roused). Two notable aspects of the behavior observed in the Fongoli group were that on the one hand, it is rare for c...Study helps explain why botulinum toxin is so deadly
...gy," Dong says. "That provides an efficient way to immobilize an animal, far easier than targeting muscles directly." Another reason for botulinum toxin's extraordinary power becomes clear from this study, Dong says. The toxin is only able to attach to a nerve cell that is working. "If the synapse between two ...Pittsburgh-based team engineers muscle, bone cell differentiation with aid of ink-jet printer
...negie Mellon's Robotics Institute, can deposit and immobilize growth factors in virtually any design, pattern or concentration, laying down patterns on native extracellular matrix-coated slides (such as fibrin). These slides are then placed in culture dishes and topped with muscle-derived stem cells (MDSCs). Ba...Velvet worm brains reveal secret sisterhood with spiders
...one's dissection tools. In the wild they use it to immobilize their prey," Strausfeld said of the 2-inch-long critters. "They're really quite extraordinary." Strausfeld and his colleagues compared the brain architecture of onychophorans with a range of arthropods, including spiders, scorpions, dragonflies, be...Chronic neuropathic, 'phantom' pain comes from affected nerve and spinal cord, not brain

Another possibility may be to suppress the immune system for the initial five days after injury. This may curtail the inflammation associated with peripheral nerves that appear...Scientists describe new way to peer inside bacteria
...also suggest new ways to harness microorganisms to immobilize things like heavy metals and radioactive contaminants," he said. Gillow will give a talk on the new method at the 230th national meeting of the American Chemical Society in Washington, D.C. on Monday, August 29, 2005 at 11:10 a.m. in room 204C of the...National Academies news: DOE should consider enhancing cleanup and stabilization
...could remove more of the residual waste and better immobilize what is left in the tanks. This could be done without delaying final closure of the "tank farm," added the committee that wrote the report. Once the bulk of the radioactive waste is removed from tanks at the Savannah River Site, DOE plans to fill th...
