High-speed pipeline revs up biomass analysis

3/11/10 | News

Researchers at the National Renewable Energy Lab are analyzing 1,000 samples of biomass at a time, finding which one, combined with the right enzyme, most eagerly gives up its sugars to be converted into biofuel. Their work is part of an effort to meet federal regulations that require the U.S. produce 36 billion gallons of biofuel by 2022.

Study validates general relativity on cosmic scale, existence of dark matter

Mar 11 | News

An analysis of more than 70,000 galaxies by physicists in the U.S. and Switzerland demonstrates that the universe—at least up to a distance of 3.5 billion light years from Earth—plays by the rules set out 95 years ago by Albert Einstein in his General Theory of Relativity.

Group: polluters use offsets to avoid carbon cuts

10 hours ago | News

According to nonprofit group Sandbag, reports the AP, major European polluters are buying their way out of making big cuts to greenhouse gas emissions by purchasing carbon offsets that pay for environmental programs in developing nations.

Electrochemical imaging tech finds TNT in fingerprints

10 hours ago | News

Scientists at the Biodesign Institute at Arizona State have hit on a new, versatile method to significantly improve the detection of trace chemicals. The technique—electrochemical imaging microscopy—was able to detect and identify TNT particles weighing less than a billionth of gram on the ridges and canals of a fingerprint.

Voltage controlled oscillator ideal for digital radio apps

11 hours ago | Tools And Technology

Crystek’s CVCO55CC-2580-2650 VCO (voltage controlled oscillator) operates from 2580 MHz to 2650 MHz with a control voltage range of 0.5V~4.5V. This VCO features a typical phase noise of -110 dBc/Hz@10KHz offset and has excellent linearity.

World’s largest clean room gets a “Webb” cam

11 hours ago | News

At 1.3 million cubic feet, the Goddard Space Flight Center’s High Bay Clean Room, where the components of the James Webb Space Telescope are now being assembled, circulates a staggering one million cubic feet of air per minutes, ensuring no more than 10,000 particles larger than 0.5 microns. Progress on the telescope can now be viewed by webcam.

Berkeley scientists find way to get physical in cancer fight

12 hours ago | News

Conventional biological wisdom holds that living cells interact with their environment through an elaborate network of chemical signals, which is most therapies rely on drugs that block chemical signals. Scientists can now show, however, for the first time, that direct physical force can also change the way cellular proteins conduct chemical activity.

OLED concept uses graphene as transparent conductor

21 hours ago | News

Researchers at Stanford University have successfully developed a brand new concept of organic lighting-emitting diodes (OLEDs) with a few nanometers of graphene as transparent conductor. This paves th...

Conquering the chaos in multiprocessor computers

Mar 11 | News

Computers should not play dice. That, to paraphrase Einstein, is the feeling of a Univ. of Washington computer scientist with a simple manifesto: If you enter the same computer command, you should get back the same result.

World crude oil production may peak a decade earlier than predicted

Mar 11 | White Papers

The American Chemical Society has made public a recent study by Kuwaiti scientists in the journal Energy & Fuels that predicts world conventional crude oil production will peak in 2014. This is about 10 years earlier than other forecasts, particularly the Hubbert model, which accurately predicted peak production in the U.S. in 1970.
