New world record magnet for chemical and biomedical research

...with a set of superconducting shim coils that fine tune the magnetic field. Fabrication of the NbTi and shim coils occurred in cooperation with an industrial partner, Intermagnetics General Corporation. The achievement of producing a uniform 21.1 Tesla field in a warm bore of 105 mm is attributed to the d...

Artificial light-dark cycles expose circadian clocks at odds with each other

...hronized so that various physical functions are in tune with each other, said Horacio de la Iglesia, a UW assistant professor of biology. But make a long plane trip or switch your 8-to-5 work schedule to begin at midnight and things can get out of kilter. "When you travel to Europe, the rest-activity cyc...

Light Biology, a biotech company based on UT Southwestern technology, bought by NimbleGen Systems

...nome necessitates this careful target selection to tune experiments to address specific questions, Dr. Garner added. A need has emerged to have rapidly customizable microarrays, making the DOC technology a valuable research tool. Dr. Garner's DOC technology and NimbleGen's Maskless Array Synthesis (MAS) t...

Scientists await first call from Beagle

...t, when its simple carrier signal (rather than the tune composed by Blur) may be picked up by Jodrell Bank radio observatory in Cheshire, UK. This has a much greater chance of success because the giant telescope is able to scan the entire side of the planet facing the Earth. Another overflight by Mars Ody...

Chimp vs. human DNA: what's in the 1% difference

...ctorin, he says, could imply that humans needed to tune the protein for specific attributes of their sense of hearing. This leads Clark to wonder whether one of the difficulties in training chimpanzees to understand human speech is that their hearing is not quite up to the task. Although studies of chimp...

Mantis shrimp fluoresce to enhance signaling in the dim ocean depths

...traviolet light. Plus, they have four filters that tune those visual pigments, and they see two or three planes of polarized light. "It's been blowing us away for years how complex the stomatopod visual system is," Caldwell said. "There's no question this is the most complex eye in the animal kingdom. It ...

Audience pick: Older violin, sweeter music?

...ition it for playing. A violin has to be played in tune -- every position and every note with the scales and ambitious music -- to be balanced, Nagyvary explained. "I'm even attempting to fake the age so that even if the screen were removed, the audiencewould not be able to tell the two violins apart...

Rice makes first rapid, sensitive whole-blood immunoassay

...l shell, researchers in Halas' group can precisely tune the color of light to which the nanoshells respond. Because near infrared light penetrates whole blood very well, it is an optimal wavelength for a whole blood immunoassay. When the antibody-nanoshell particles are placed into a solution of blood con...

Mutants from a lowly weed may solve maladies

..., known by scientists as AtCPLs and AtHKT1. AtCPLs tune plant gene expression under stressful environments, and AtHKT1 allows salt to enter plants. Until the AtHKT1 discovery, no one knew how sodium gets into plants, Purdue reported. With that information and wide collaboration, Koiwa hopes to steer conti...

Rice develops nanosensor for precision chemical analysis

...g shell, researchers in Halas' group can precisely tune the electric and optical properties of nanoshells. Nanoshells are so useful for enhancing SERS and for other applications because of their size and precise structure. Nanoshells are just slightly larger than the size of molecules, measuring just a fe...

More than 450 schools from across the U.S. and several other countries will use the provided resource guides, curricula and video about the deep sea to guide them ...

Biomedical scientist testing nanoparticles as early cancer detection agent

...e infrared spectrum, scientists are able to finely tune nanoparticles to carry out tracking tasks traditionally accomplished using organic dyes. Nanoparticles have characteristics that are more desirable than dyes, however. Dyes fade more quickly, they can be toxic to cells, and they cannot be used togeth...

First biologic pacemaker created by gene therapy in guinea pigs

... work comes," says Marbán. "We need to fine tune it -- develop controlling strategies, find the optimum place to re-engineer the cells in the heart, control the frequency of the new pacemaker. But there is light at the end of the tunnel." In the vast majority of heart muscle cells, a particular cha...

Researchers develop mouse model of Rett syndrome

...function and strengthen synapses. Experiences fine tune the brain. Perhaps more complex tasks require the input of this protein and its loss is now instrumental. Things fall apart and people regress. Perhaps key genes that are important at certain times are not put in place. We don't know the mechanism bu...

"In the case of an orchestra, a fundamental 'C' note is extracted from a mixture of fundamental and harmonics produced by a bassoon. In the case of the vibrissa system, this fundamental frequency may serve to synch...

Study suggests infants 'tune in' to familiar face groups

... in" to the types of faces they see most often and tune out other types. This implied that younger infants, who have not had enough experience to become specialized in discriminating human faces, ought to do better than older infants or adults at telling faces of other species apart. In tests of adults, ...
