New device for ultrafast optical communications

New device for ultrafast optical communications

A new device invented by engineers at UC Davis could make it much faster to convert pulses of light into electronic signals and back again. The technology could be applied to ultrafast, high-capacity communications, imaging of the Earth's surface and for encrypting secure messages.

Climate tipping points may arrive without warning

Climate tipping points may arrive without warning

A new Univ. of California, Davis, study by a top ecological forecaster says it is harder than experts thought to predict when sudden shifts in Earth's natural systems will occur—a worrisome finding for scientists trying to identify the tipping points that could push climate change into an irreparable global disaster.

Genome sequence for the domestic horse to be unveiled

The whole genome sequence of the domestic horse has been completed by the genome-sequencing center of The Broad Institute of MIT and Harvard, in collaboration with an international team of researchers that includes scientists at the Univ. of California, Davis. Findings from the genome sequence have important implications for improved breeding of horses, which constitute a $39 billion industry in the United States alone, and for studies of human health.

Dominant chemical identified that attracts mosquitoes to humans

Dominant chemical identified that attracts mosquitoes to humans

Scientists at the Univ. of California, Davis, have identified the dominant odor naturally produced in humans and birds that attracts the blood-feeding Culex mosquitoes, which transmit West Nile virus and other life-threatening diseases. The research explains why mosquitoes shifted hosts from birds to humans and paves the way for key developments in mosquito and disease control.  

Novel chemistry for ethylene and tin

New work by chemists at UC Davis shows that ethylene, a gas that is important both as a hormone that controls fruit ripening and as a raw material in industrial chemistry, can bind reversibly to tin atoms. The research could have implications for understanding catalytic processes.

Purer water possible with a single atom substitution

Purer water possible with a single atom substitution

By substituting a single atom in a molecule widely used to purify water, researchers at Sandia National Laboratories have created a far more effective decontaminant with a shelf life superior to products currently on the market.

Iron men calculate initial composition of Earth's mantle

Just as DNA helps biologist explain the tale of life, isotopes help geologists learn about the mantle, the vast, viscous interior of our planet. Two researchers combined a month’s worth of supercomputing power with mass spectrometric analysis data to provide for the first time a distribution map of iron isotopes—the most common element in the mantle—around the time the Earth formed.

Lunar tires, space MRSA, and resonating microfluidics

Lunar tires, space MRSA, and resonating microfluidics

I typically attend the annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy each year in pursuit of specific coverage. This year, I sought out candidates for coverage in a vacuum technology article, and pulled together some instruments for a spectroscopy guide. But as busy as that kept me, it wasn’t all mass spectrometers and vacuum pumps on the show floor.  

A clean energy America…is it coming or not?

A clean energy America…is it coming or not?

Almost a year ago, the buzz during the downturn was that the economic stimulus will help boost jobs in a sort of national improvement program reminiscent of the 1930s. Our coal would be phased out. Our grids would get smart. Our cars would get hybridized.
