Called PUMA for plutoniummeasurement and analysis, the sensor can be embedded in a variety of materialsor literally wrapped, like fingers, around objects of vario......Phthalates are chemical plasticizers used inmaking flexible vinyl products such as shower curtains, medical devices such astubing and IV bags, upholstery, raincoats, balls and soft squeeze toys. The new NTP Center for the Evaluation of Risks to Human Reproductionwill assemble a dozen or more scienti...Professor Will Connect With Students Live From China Dinosaur Site
...d, we often have unexpected results and have to be flexible in what can be done, and this generates a flurry of ideas across the Internet. During the Argentina expedition, they just about wore us out with the furious rate they were typing to us."...Flexible Membranes - Moving Through The Twilight Zone Between The Nano- And The Microworld
...hlarger and can be tens of micrometers. Therefore, flexible membranes are able tobridge the gap between the nano- and the microworld. So far, our understanding of these structures was based on two rather differenttheoretical approaches. On the one hand, the behavior of membranes on themicrometer scale is well...Waste Asphalt Doesn't Pollute Groundwater, UF Researchers Say

...ng out the flat spots of the Tinkertoy wheels with flexible brass strips. Soon, the hand-sized gadget was tottering down a gentle slope, tilting from side to side but steadily walking on and on and on. But, it couldn't stand still.

... optimization model, and theresults provide a more flexible approach as well as a moreeconomical approach. "We found that you can get the same numberof species usingmore land and locations at a much cheaper cost than just lookingat the species distribution," said Camm. "If you factor in theland values, you mi...Vascular Surgeons Test New Treatment For Abdominal Aneurysms
..., or X-ray imaging. The stent's metallic frame is flexible atcold temperatures but stiff at body temperature. This enables the cloth supportto expand to fill the necessary space, excluding the aneurysm. Traditional treatments for abdominal aortic aneurysms require extensivesurgery to sew a similar b...3-D Structure of Human Tumor-Suppressor Protein Produced
...rs to complete because the p16 proteinis unusually flexible compared to many other protein molecules. “Because of this flexibility,” said Tsai, “the moleculewas in constant motion, making it difficult to make the measurements weneeded to establish the structure.” Tsai and his research te...Harbor Branch Oceanographic Institution Receives $1.1 Million Grant From National Cancer Institute
...ese compounds bind to, and "freeze", the otherwise flexible cytoskeleton, which results in killing of the tumor cell. Discodermolide, however, appears to be up to 80 times more potent than Taxol in killing human tumor cells and is also effective in killing tumor cells which have developed "resistance" agains...Wonder Thread: UD Scientists Report First Protein With Collagen And Elastin-Like Domains

To test how RTP works, the researchers had to create a mutant versionof the protein that would not interact with the helicase but wouldn't bedeformed beyond recognition. ...Duke's Russian Laser Making Ultraviolet Light And Gamma Rays
