Research finds that circadian rhythms dominate all life functions

...llation can become chaotic in states of consistent lighting or lack of lighting, but it never stops. Comparing the complex system in which the genes function to an AC power grid, Ptitsyn made the discovery by plotting the expression of 20,000 genes on a scale of frequency, or intensity, over a two day perio...

Computer scientists join in search for ivory-billed woodpecker

...bird ?isn't regular. It's deformable, and from the lighting conditions, it's very difficult to capture." The robot stores images of the birds it has recorded in the hard disks of its computer, Logic Supply Inc.'s S-625F. The computer as well as the cameras are housed in weatherproof cases. "If you put ...

...ate impact on the production and use of artificial lighting in this country,?said Richard Stevens, Ph.D., an e...several papers on the subject. “This might include lighting with a wavelength and intensity that does not disrupt melatonin levels and internal timekeeping.?/p&...

You will remember this

...t tool to show not just what bits of the brain are lighting up but also what triggers it to light up and when. In this test, the important thing was to find out whether brain activity before an event has an impact on memory or whether, as was previously thought, it's just brain activity after an event that ...

Grid bridges 4,800 miles for molecular repositories

...The PNNL node on the BioSimGrid coincided with the lighting of a new high-speed, high-capacity fiber optic connection between PNNL's campus in Richland, Wash., and Seattle. This connection made it possible for the laboratory to accept the BioSimGrid Consortium's invitation to deploy the network infrastructure...

A 'dimmer switch' for genes

...t behaved the way a dimmer switch does to regulate lighting in a gradual manner." In studying how this fine-tuning worked, they also discovered that conventional wisdom failed to fully describe how proteins function. It was known that proteins have regions with parts that are fixed in space, with a definite ...

Researchers find ways to turn manure into power

...nd incentives to find alternative fuel sources are lighting a fire under research to turn biomass materials such as manure into energy. Texas Senate Bill 20, signed this week by Gov. Rick Perry, compliments research underway to determine how and where biomass can be used. The new law requires more renewable ...

Study of energy and health in Africa focuses spotlight on charcoal and forest management

... land, cutting down a tree or two, chopping it up, lighting it, covering it with dirt, and then hovering around it for two to four days while it becomes charcoal," Kammen said. "It's no surprise it's not generally a high-efficiency operation." The authors found that by creating the technological and policy t...
