If someone is charged up, the color of their face might change, but they don't immediately pull off one of their arms, only to reattach it as a third leg. With some molecules, however, the situation is quite different - for example, in a gold cluster with seven atoms. In a charged state, the atoms arrange themselves differently than when they are uncharged.
DURHAM, N.C. –- As microbes in the soil break down fallen plant matter, a diet "balanced" in nutrients appears to help control soil fertility and the normal release of the greenhouse gas carbon dioxide into the atmosphere.
When plants drop their leaves, stems and twigs, this organic matter slowly becomes part of the soil as a result of decomposition, which is facilitated by bacteria and other microbes. This process adds plant nutrients to the soil and releases carbon dioxide into the atmosphere.
DURHAM, N.H. – University of New Hampshire researchers have tagged one male and two female leatherback turtles off Cape Cod. They are the first free-swimming leatherbacks ever tagged in New England.
The 700 – 800-pound leatherback turtles, an endangered species, were tagged July 17, 26 and 29 with GPS-linked satellite tags that transmit nearly real-time tracking data, allowing scientists to better understand these elusive, highly migratory giants to enhance their survivability.
Have you ever wondered what our world would look like stripped bare of all plants, soils, water and man-made structures? Well wonder no longer; images of the Earth as never seen before have been unveiled in what is the world's biggest geological mapping project ever.
The project represents another first for the CSIRO PCC program - the first capture of carbon dioxide in China using a PCC pilot plant. It begins the process of applying the technology to Chinese conditions and evaluating its effectiveness.
PCC is a process that uses a liquid to capture carbon dioxide from power station flue gases and is a technology that can potentially reduce carbon dioxide emissions from existing and future coal-fired power stations by more than 85 per cent.
A report just released in the most recent issue of the Bulletin of the American Meteorological Society offers hope that a new high-resolution storm surge modeling system developed by scientists at Stony Brook University will better be able to predict flood levels and when flooding will occur in the New York metropolitan area, information crucial to emergency managers when planning for impending storms.
A part of the global food crisis is the inefficiency of current irrigation methods. More irrigated water evaporates than reaches the roots of crops, amounting to an enormous waste of water and energy.
Tel Aviv University researchers, however, are investigating a new solution that turns the problem upside-down, getting to the root of the issue. They are genetically modifying plants' root systems to improve their ability to find the water essential to their survival.
The Root Cause of Wasting Water
Dartmouth researchers identify an important gene for a healthy, nutritious plant.
The research paper, published with colleagues from Colorado State University and the University of South Carolina, appeared in the early online edition of the Proceedings of the National Academy of Science during the week of July 21.
Batavia, Ill.— Scientists of the DZero collaboration at the US Department of Energy's Fermilab have announced the observation of pairs of Z bosons, force-carrying particles produced in proton-antiproton collisions at the Tevatron, the world's highest-energy particle accelerator. The properties of the ZZ diboson make its discovery an essential prelude to finding or excluding the Higgs boson at the Tevatron.
Boulder, CO, USA – GSA's August GEOSPHERE articles are all about technology and modeling: how geographical information systems increase understanding of shear-zone growth; fault structures as fingerprints for rockslide motion and direction; a reconstruction of the Cenozoic geologic history of the southern Tobin Range, Nevada; thermal infrared and visible/short-wave infrared sensing help map metamorphic and igneous terrains in Morocco; and CT scans provide insight into the evolutionary traits of foraminifera, possibly leading to improved reconstructions of past environments.
