...about its biochemical properties, and to determine whether
higher forms of life have similar cassettes. "We're now searching the genomes of higher life forms," Miller said. Miller believes his research team will be able to exploit the new knowledge to generate proteins in the laboratory that will bind ...
Scientists find nanowires capable of detecting individual viruses
...anowire arrays detect viruses suspended in fluids, whether
bodily or otherwise. Lieber says that any anti-bioterror device built around nanowires' virus-detecting capabilities would most likely marry the technology with a microfluidic apparatus that would draw in air, suspend any airborne particles in a liqu...
Scientists discover potential new way to control drug-resistant bacteria
... about its biochemical properties and to determine whether
higher forms of life have similar classes of genes. He believes that, in time, they will be able to use the knowledge gleaned from this discovery to generate proteins in the laboratory that will bind to almost any molecule of interest. ...
Termites could hold the key to self-sufficient buildings
...team of engineers and entomologists* is looking at whether
similar principles could be used to design buildings that need few or no mechanical services (e.g. heating and ventilation) and so use less energy and other resources than conventional structures. Loughborough University is leading this innovative p...
NSF awards 22 new projects for plant genome research
...stand how DNA packaging in the nucleus can control whether
genes are turned on or off, a step toward providing tools for manipulating gene expression in maize and other crop plants. University of Georgia researchers will study the structure and function of maize centromeres, which play a central role in cell...
Health of world's sea lions the focus of Wakefield Symposium
...le others increase. Insights can also be gained on whether
trends in the abundance of sea lions are related to fishing activities through food dependencies or more directly through control or conservation measures. A better understanding of the biology of sea lions is urgently needed. This symposium will si...
UAF scientists discover new marine habitat in Alaska
... samples and further testing are needed to confirm whether
the second species is indeed new. Scientists believe rhodoliths have been present in the world's oceans since at least the Eocene epoch, some 55 million years ago. Because rhodoliths probably grow very slowly in Alaska's cold waters, Riosm...
Study reveals why eyes in some paintings seem to follow viewers
...ewing direction. They were particularly interested whether
points that appeared to be closest or farthest in depth relative to other neighboring points would remain the same when the picture was observed at different viewing angles. They also wanted to determine how the relative magnitude of the perceived de...
Key stimulator of colorectal cancer identified
...n Nashville, Tennessee and colleagues investigated whether
the ability of PGE2 to promote CRC is dependent on PPARd. The researchers found that PGE2 indirectly activates PPARd via a signaling pathway that promotes cell survival and polyp formation. Polyps are abnormal growths in the colon and rectum that ...
Prion propagation: Avoiding the toxic oligomer
...rlying amyloid diseases. It is not clear, however, whether
amyloids follow a progression from monomer to oligomer to plaque. Using the yeast prion protein Sup35 to study how amyloids form, Jonathan Weissman and colleagues show, surprisingly, that amyloid plaque formation can occur in the absence of the putat...

selective inhibition of the Sonic Hedgehog (Shh) signaling pathway could interfere with the development and progression of the disease. Previous studies have implicated the Shh pathway in human medulloblastoma formation. Treatment of the mice with...
