Neuronal 'traffic jam' marks early Alzheimer's disease

..., enough to cross a critical threshold and tip the scale toward disease." Goldstein emphasized that any application of these findings to potential diagnostic tests or new therapies remains speculative at this time. "However, if tracers could be developed that would reflect transport function, there could ...

Tiny particles could solve billion-dollar problem

...er of CBEN's environmental research programs. "The scale of TCE contamination is enormous, so any new scheme for TCE remediation has got to clean large volumes of water very quickly for a just a few pennies." Hughes, Wong and their collaborators hope to develop a device that would include a cylindrical pu...

Computers to be used to find blueprint for new influenza drug

...ays. But some outbreaks can cause death on a large scale ?the world-wide outbreak in 1918 killed more people than the First World War itself. We may now be facing another flu outbreak, this time originating from chickens in Asia. “If we are successful, we will have taken important steps in finding a new w...

Breakthrough Microarray-based Technology for the Study of Cancer

This advancement, along with the possibility itprovides to correlate genomic copy alterations with mRNA abundance andprotein abundance, is going to incite a huge body of experimentationand publication am...

The secret lives of whales

...s. “Suddenly you realize that the whale’s sense of scale is ocean basin sized —one song note is 20 miles long and can illuminate the entire basin,?he says. Clark has observed that the distribution of singers is closely matched to the distribution of zooplankton, and suspects that shifts in singer distribu...

Researchers reveal the infectious impact of salmon farms on wild salmon

Scientists decipher genome of fungus that can cause life-threatening infections

...lso catalogued, for the first time on agenome-wide scale in fungi, examples of "alternative splicing" and"antisense" transcripts, in which the gene on one strand of the DNAdiffers from the counterpart gene on the opposite strand. Researchersalso identified a high percentage of transposons (moveable element...

Researchers trace evolution to relatively simple genetic changes

Marine sponge yields nanoscale secrets

...of valuable materials. Nature produces silica on a scale of gigatons –?thousands of millions of tons –?thousands-fold more than man can produce, said Morse. "This biosynthesis is remarkable because this nanoscale precision can't be duplicated by man." Besides this remarkable precision, nature manages to p...

Insects, viruses could hold key for better human teamwork in disasters

...d, adding that "the resulting software systems can scale to networks with hundreds or thousands of first responders, as well as withstand unresponsive participants and poor communication channels. "This behavior is very similar to how rumors or fads spread in society and viruses spread in populations, bot...
