Going To Extremes To Improve Human Health

...ent a name change in July 2004.) "In this current day of rapid discovery in genetics and cellular biology, it is more important than ever that some attention be focused on the research-training of individuals who will make sense of the explosion of available information by connecting these discoveries t...

Plankton can run, but can't hide from basking sharks

...en, sometimes staying at greater depths during the day and then feeding near the surface at night but at other times reversing this behaviour in an attempt to throw some of their predators (eg fish larvae and predatory invertebrates such as arrow worms) off their trail. However, this study shows that bas...

Female volunteers prepare for a second 'bedrest'

... tests will be carried out on the volunteers every day to prevent the risk of thrombosis. ...

Researchers devise new technique for creating human stem cells

...archers said that -- while the technique might one day be used along with SCNT, which involves the use of unfertilized human eggs -- technical hurdles must be cleared before the new technique sees widespread use. It is more likely that the new technique will see immediate use in helping to accelerate und...

Study identifies gene in mice that may control risk-taking behavior in humans

... the brain." Further research is needed that one day could explain why some people react the way they do to fear, or why they take risks, Olson said. "The question is, are there differences in the neuroD2 gene-coding sequence or differences downstream of the neuroD2 pathway during brain development tha...

Structures of marine toxins provide insight into their effectiveness as cancer drugs

...tic chemists hope that actin-based drugs might one day rival the success of Taxol, a powerful drug derived from a natural product that keeps breast-cancer cells from dividing. "Actin-based drugs have not yet been used as successful drugs as have those that target microtubules, like Taxol, in part becaus...

Elderly mice yield clues to the process of growing old

...eath in aging." If true, the new insights may one day lead to opportunities to stave off old age through drugs that could prevent the gathering of genetic defects in mitochondrial DNA, genetic material that resides outside of the nucleus of a cell and that helps power critical cell processes. Such insi...

'Sinkers' provide missing piece in deep-sea puzzle

...they observed an average of about four sinkers per day for every square meter of deep seafloor. In other words, a patch of seafloor the size of a large dinner plate might receive carbon from about 100 sinkers over a year's time. To complete their study, the scientists also needed to know how much carbon...

Envisat and ERS-2 reveal hidden side of Hurricane Rita

...r. ERS-2 joins in Rita observations The same day Envisat acquired its ASAR image of Rita, its sister spacecraft ERS-2 also made complementary observations of the hurricane's underlying wind fields using its radar scatterometer. This instrument works by firing a trio of high-frequency radar beams ...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...days to tell you if a virus is present and another day or so to tell you which virus it is." Crowe lists three potential benefits for such an early detection system. It can: * Increase the proper use of antiviral medicines. Although such medicines have been developed for some respiratory viruses, t...

New imaging technology shown to detect pancreatic inflammation in type 1 diabetes

...chers, however, offer hope that physicians may one day be able to identify individuals with preclinical type 1 diabetes, and to assess the effectiveness of therapies much earlier than is now possible. Findings of the study will be published in the September issue of the Journal of Clinical Investigation....

Leading scientists rank endangered dolphins, porpoises most in need of immediate action

...ost 1,000 whales, dolphins and porpoises die every day in nets and fishing gear. Some species are being pushed to the brink of extinction," said Karen Baragona of WWF's species conservation program. "We developed this ranking to help governments and aid agencies target their investments for the best retu...

Unweaving amyloid fibers to solve prion puzzles

...e electrical wires, opening the possibility of one day incorporating them into integrated circuits. "These findings are quite relevant for the material sciences," says Lindquist. "The more we understand about how these fibers work, the more we can get them to self-assemble," a key advantage for nanoscal...

Hospitalizations because of chicken pox down dramatically since implementation of vaccine

... of responding to outbreaks of varicella (e.g., in day care or school settings) may be substantial and were not included in the original analysis [in another study]." "Third, and perhaps most important, there is great uncertainty about the extent to which parents and other adults experienced reductions ...

Muscle repair: Making a good system better, faster; implications for aging, disease

...ll mice still showing little, if any, recovery. By day 20, the three mouse strains' relative muscle strength followed a similar pattern: PAI-1 null 90%, WT 75% and uPA null 35% of pre-injury force. Koh noted that PAI levels normally increase in muscle after damage, which may limit the repair process. "S...

Columbia scientists develop cancer terminator viruses

...xcited about these results and the prospect of one day using a form of the cancer terminator virus in human clinical trials," said Dr. Fisher, the study's senior author. "While the results of these trials need to be investigated further and replicated in future trials, we believe that viral-based therap...

New understanding of jet lag

...eople who suffer from sleep disorders. In nature, day and night cycles shift slowly as the seasons change. The body is able to adjust to the slow changes and is in fact adapted to these seasonal cycles. But transmeridian flight is an unnatural manipulation of the light cycles, forcing the body to try to...
