Duke Geologists Explore Alternative Way To Measure Ice Age Sea Bottom Temperatures
...lls could be unacceptably changed as the specimens deteriorate over time. "What Gary is trying to do is determine temperature changes independent of changes in the isotopic composition of sea water," Baker added. "Frankly, our method is quite untested. But if we are really able to do that, that would be monument...Feature: Biomaterials Are Transforming Medicine
...controlled release ofmedicines that would normally deteriorate in minutes to be released slowly overfour months. "I'd like to think these are the tip of the iceberg," said Langer. Researchers are also working on ways to deliver growth hormones and methods toprovide a constant release of insulin for diabe...New targets for nerve diseases, nerve regrowth: It's all in the handshake
... surroundings which, when broken, causes nerves to deteriorate ina way apparently identical to a variety of neurodegenerative diseases. Theresearch adds new insight on nerve disease as well as a new focus for researchon stimulating nerve cell regrowth in the brain and spinal cord. Although the studies w......that causes certain nerve cells in the cerebrum to deteriorate and die. It is a progressive degenerative disease marked by involuntary, jerky movements in the arms, neck, trunk and face. Other symptoms include a wide, prancing gait, hesitant speech and intellectual deterioration. Symptoms appear in the fourt......hips. But these artificial hip implants can slowly deteriorate and eventually break down due to wear, often because of inadequate lubrication. (COLL 413, Wednesday, April 4, 5:00 p.m.) Thursday, April 5 After-the-fact sunscreen - Scientists have synthesized an artificial enzyme they believe can repair...New transgenic rat model of ALS expands research possibilities
...ats are "symptom-free" for a longer time, but then deteriorate much more rapidly than the mice. While the faster disease progression in rats might hide subtle effects of some potential treatments, the scientists point to the benefit of a model that can easily test stem cells and advance understanding of the dise...Tether for water channels found: May impact research on brain swelling
... architecture. "The standard answer to why muscles deteriorate in these diseases is that the muscular architecture is weakened," says Neely. "We've shown that the same protein complex involved in muscular dystrophy also holds AQP4 in its appropriate locations. If that complex is disrupted, AQP4 is in the wrong p...Patch delivers longer, deeper relief from dental pain

Also, patients needing an anesthetic injection on the upper jaw or the roof of the mouth may benefit from t...Damaged DNA synthesis enzyme shown to cause progressive muscle weakening
...y to this rare affliction in which the eye muscles deteriorate and the patient must move his head, rather than his eyes, to follow an object. However, they said, the principle of repeated, copying errors applies to other mitochondrial degenerative conditions as well, including aging itself. The answer to the ri...Insects' survival, mating decrease with age in wild, researchers discover
... Nov. 28 issue of Nature. "We found that the flies deteriorate over their lives. As they get chronologically older, their chances of dying by the next day increase," says Bonduriansky. "While their probability of death increased, their probability of mating decreased. A decrease in both survival and reproduction...Ecowar looming with sunken wartime wrecks
... says. "With every year that passes, these vessels deteriorate more, and the risk of significant oil release becomes more likely." When the tanker Prestige sank some 200 kilometres off the north-west coast of Spain on 19 November 2002, many thought that the cold waters and depth of 3.5 kilometres would solidify ...U. of Colorado professor pioneering tissue engineering from knees to hearts to brains
...ced with the heart valves of pigs, they eventually deteriorate and have to be replaced. Anseth and a team led by Chair Leslie Leinwand of molecular, cellular and developmental biology now are designing gel for various heart valve cells. "This is more complicated because it requires the polymer scaffold to give ...
