Sweet 'water taste' paradoxically predicts sweet taste inhibitors

...ons. Galindo-Cuspinera subsequently observed that strong sweetness returned when the high concentrations of saccharin were rinsed from the mouth with water. Working with Breslin, she next discovered that high concentrations of saccharin inhibit the sweetness of any other sweetener tasted at the same tim...

University of Utah to help build bionic arm

...tside world and your own movements, and that is as strong and graceful as an intact, biological limb," says bioengineer Greg Clark, the University of Utah's principal investigator on the project. "That's what our researchers, teaming with others around the world, are setting out to achieve. ?People's arms a...

"Now's the time to recognize the strong connections between sustainable economic development, a healthy environment, and successful species conservation," said Ginette Hemley, vice president for species conservation, World Wildlife Fund. "WWF's new report provides clear evidence that when ...

Mayo Clinic collaboration discovers protein amplifies DNA injury signals

...ce amplified, even low-level damage signals become strong enough to activate the cell's natural repair processes while the injury is most tractable to repair. How this "distress call" was communicated wasn't clear until this finding, which appears in the January 20 issue of Molecular Cell ( http://www.mo...

Lack of a key enzyme dramatically increases resistance to sepsis

This new discovery suggests that caspase-12 antagonists could be a potentially useful in the treatment of sepsis and other inflammatory and immune disorders. The study was published in the April 20 edition of the journal Natur...

New hybrid virus provides targeted molecular imaging of cancer

...or of the Cell study says, "we were pleased by the strong effects of gene transfer in mouse models of common diseases such as breast and prostate cancer." Their next step was to work closely with the team of M. D. Anderson researcher Juri Gelovani, M.D., Ph.D., chair of the Department of Experimental Diagn...

When mice choose mates, experience counts

...says that the female mice's mate preference was so strong that they even preferred the combined male/female scent when it was tainted with the scent of infectious parasites, opting for that over the scent of a healthy lone male. "Male odors can provide female mice with information on their quality, conditi...

Expedition discovers marine treasures

Protein 'nanosprings' most resilient found in nature

...enerating tension in cell membranes. The unusually strong tendency of ankyrin repeats to refold might also play a significant role in the function of proteins having fewer repeats. "Ankyrins appear to have a very unusual structural design ?consisting of short anti-parallel alpha helices that self-assemble ...

Less is more, gene study shows

.... "It's a delicate balance---you don't want it too strong or too weak." The normal function of CASPASE12 is to keep the response from being too strong, and that probably served humans well at one time. But then, "during human evolution, either because of an environmental change or because of some other gene...

Rhinos clinging to survival in the heart of Borneo, despite poaching

...pecies, the survey results were not released until strong protection measures could be put in place in the areas where the rhinos are found. Those security measures were recently installed. WWF and partners last month launched a five-year project called "Rhino Rescue," which will organize rhino protection u...

Forsyth scientists gain greater understanding of how embryos differentiate left from right

...a novel component: an ion transporter that creates strong natural voltage gradients and pH changes. The pump that normally acidifies subcellular compartments was shown to control embryonic laterality at very early stages. Their findings further challenged the previously held hypothesis that cilia (short hai...

U-M scientists identify major psoriasis susceptibility gene

...o psoriasis," Nair says. "Many studies confirmed a strong association with the MHC, but no one could determine which gene in the MHC was involved in psoriasis." In a previous study, Nair and his U-M colleagues narrowed the search for the PSORS1 gene down to a 300,000-base-pair segment of chromosome 6 that ...

Carbon cycle was already disrupted millions of years ago

...taceous periods were characterised by a relatively strong increase in 12C. The analyses have shown that this was caused by a sudden large-scale release of carbon from stocks stored in the ocean floor or peats and bogs. The atmospheric carbon dioxide concentration is increasing as a consequence of the larg...

El Nino events affect whale breeding

The results are published this week in the On-line journal Biology Letters. Southern right whales migrate from the South Atlantic to the Southe...

Unraveling the mysteries of poison

Applying these new spectroscopic methods, scientists are now better understanding the pharmacology and physiology of potassium channels. This could...

U of S researchers develop new vaccine candidate against hepatitis C

Because HCV does not infect mice, mice were challenged with a carrier virus containing the hepatitis C protein. The levels of HCV protein in immunized mice us...
