Ophthalmologists and physicists team up to design 'bionic eye'

...is." The amazing grace of physics The new design answers major questions about what's feasible for bionic devices. Biology imposes limitations, such as the needs for a system that will not heat cells by more than 1 degree Celsius and for electrochemical interfaces that aren't corrosive. Current retinal imp...

Was Agns Sorel, the first official royal mistress of France, poisoned?

...f skin of Agns Sorel have been studied and suggest answers to her death. The way she died is not known yet, however, incredibly high rates of mercury have been found in her mortal remains.

Researchers call for expanding the repertoire in studying birdsong

...to ask all kinds of questions and get all kinds of answers that you can't with any single species." The researchers said scientists need to be cautious about regarding the behavior of one or two species as typical of all songbirds in general. "Settling on one species is risky," said Brenowitz, "because it ...

Overall data analysis was based at Massachusetts General Hospital at Harvard Medical School. Specially ...

Why is the helix such a popular shape? Perhaps because they are nature's space savers

...ictated by bonds between molecules. But that only answers how a helix is formed and not why they are that shape," said Randall Kamien, a professor in Penn's Department of Astronomy and Physics. "It turns out that a helix, essentially, is a great way to bunch up a very long molecule, such as DNA, in a crowd...

Also participating the project were Kathryn Cleaver and Thamara Abouantoun of the NIMH Unit on Neuroplasticity. Dr. Dayer's work was ...

How many comparative genomes are enough?

...escribes a mathematical model that offers detailed answers to this question. "We shouldn't make these decisions based on seat-of-the-pants intuitions," Eddy said. "It's important to lay out the case that these genomes really do have tremendous value for analyzing the human genome sequence." According to Edd...

Gene sequencing explains bioremediation 'bug'

...ming bioremediation industry, based on Strain 195, answers the first. "Strain 195 has a relatively small genome, only about a third the size of E. coli's in base pairs, but it's a highly adaptable one with clusters of genes called mobile genetic elements," says Cornell professor of microbiology Stephen H. ...

New method simplifies search for genetic changes associated with disease

...l's DNA and sequence it." Direct genomic selection answers a growing need for what geneticists call resequencing -- sequencing the same genetic region in many individuals. Scientists measure DNA by its individual units of code, which are known as base pairs. Current automated DNA sequencing technology can pr...

Vollum Institute discovery may unlock human genome
