| Plant genetic advance could lead to more efficient conversion of plant biomass to biofuels Posted: 02 Jan 2015 02:27 PM PST Plant geneticists have sorted out the gene regulatory networks that control cell wall thickening by the synthesis of the three polymers, cellulose, hemicellulose and lignin. The advance may help manipulate the polymer-forming processes to improve the efficiency of biofuel production.       |
| Posted: 02 Jan 2015 12:04 PM PST In experiments using ultracold atoms and laser light, researchers have measured a stepwise change in conductivity as the atoms pass through tiny structures. This is the first time that this quantum effect has been observed for electrically neutral particles.  |
| New information on environmental impacts of stump wood energy through 3D modelling Posted: 02 Jan 2015 08:33 AM PST Tree stumps and root systems are a significant but controversial source of bioenergy in Finland due to their environmental impacts. Now Finnish and Norwegian researchers have developed a new method that can produce accurate three-dimensional (3D) models of recovered stumps and root systems. These models provide new information on the impacts of stump wood energy on the carbon sink capacity of forests, the biodiversity of forest nature and the soil structure of recovery areas. Tree stumps and root systems account for approximately 15% of the energy wood harvested from Finnish forests. Tree stumps are recovered from one in every ten clearcutting areas, totalling some 10,000–20,000 hectares annually, which is, at its highest, equivalent to an area the size of Helsinki.  |
| Technology innovations spin NASA's SMAP into space Posted: 02 Jan 2015 05:44 AM PST Scheduled for launch on Jan. 29, 2015, NASA's Soil Moisture Active Passive (SMAP) instrument will measure the moisture lodged in Earth's soils with an unprecedented accuracy and resolution. The instrument's three main parts are a radar, a radiometer and the largest rotating mesh antenna ever deployed in space.  |
| Innate behaviour determines how we steer our car Posted: 02 Jan 2015 04:16 AM PST A 70 year old mystery in traffic research has been solved: an until now inexplicable jerkiness when we steer a vehicle. The discovery may lead to safety systems in cars that can correct dangerous steering movements before they occur. "With the driver model I have developed, it is possible to predict what drivers are going to do with the steering wheel before they do it. It is possible to predict how far the driver is going to turn the wheel, right when the person starts a wheel-turning movement. It's like looking into the future," says a researcher.  |
| Ten exciting astronomy stories from 2014 Posted: 31 Dec 2014 08:37 AM PST Looking back at the science news released by the National Radio Astronomy Observatory (NRAO) in 2014, the staff scientists at NRAO selected what they believe are the top 10 stories based on both scientific impact and public interest.  |
