Controversial Theory Says DNA Can Be Pushed To "Dark States"

...e, vibrating "dark state" in which they could easily mutate and not fully recover from photonic damage. The lifetime of the dark state is not long – a nanosecond is one billionth of a second. But it's more than enough time for DNA mutations to happen, Kong said. And the existence of this dark state raised quest...

DOE-funded research projects win 46 R&D 100 Awards for 2009

...-Power Silicon Microphotonic Communications Platform The ultra-small components enable optical data transmission and routing on a silicon platform at nanosecond switching speeds with up to 100-times less power consumption and 100 times the bandwidth density compared to traditional electronic approaches. C...

Healing wounds with lasers, vehicles that drive themselves, other cutting-edge optics

... are too fast to be seen by the human eye. Typically the signal consists of a voltage level that changes quickly moment by moment (over millisecond to nanosecond timescales). What is seen on the screen of the scope is a waveform whose value is graphed along the vertical axis as a function of the horizontal axis...

Candy-coating keeps proteins sweet

...he team used neutron scattering to determine that rapidly solidified sugars preserve such proteins best when they suppress molecular motions lasting a nanosecond or less. Their latest experiments center on the hydrogen bonding that makes the sugars rigid. They have shown that the lifetimes of these bond network...

Scripps research study reveals structural dynamics of single prion molecules

...asures time fluctuations in fluorescent emissions from tagged proteins, which provided information about changes in shape of Sup35 taking place on the nanosecond timescale (billionths of seconds). A third technology, single molecule fluorescence coincidence, was used in an unusual way-to prove that the pr...

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

...earchers, an accurate understanding of the key molecular events required the simulations to run for some six million time steps over 12 nanoseconds (a nanosecond is one billionth of a second) in order to capture enough of the motion and shape changes of the enzyme as it interacted with the cellulose surface. ...

Mussels evolve quickly to defend against invasive crabs

...ofessor of zoology James Byers and published in the Aug. 11 issue of the journal Science, indicates that such a response can evolve in an evolutionary nanosecond compared to the thousands of years previously assumed. The paper is called "Divergent induced responses to an invasive predator in marine mussel popul...

...gineered a molecular switch that turns on the fluorescence." The probe's green fluorescent burst lasts little more than a billionth of a second - a nanosecond - but just long enough to separate it from surrounding signals, according to co-author Nicholas Turro, Ph.D., the William P. Schweitzer professor of c...

Debate over `intelligent design' is a not-so-wise diversion from science education

...h will continue to believe as they wish. The real question is not evolution versus intelligent design, but whether this debate is worth more than a nanosecond of public effort? Given the more urgent challenges in science education today, it would be far more useful if the president turned his attention to Am...
