Researchers participating in the California NanoSystems Institute (CNSI) at the University of California at Santa Barbara (UCSB) and at Los Angeles (UCLA) have invented a new technique for producing “Ultra High Density Nanowire Lattices and Circuits”–the title of their paper being published expeditiously at 2:00 p.m. March 13 on the “Science Express” website, Science Magazine’s rapid portal for publication of significant research findings to appear subsequently in print in Science.

Discovery highlights molecular screening work at Institute of Chemistry and Cell Biology
Boston, Mass. — Scientists studying how cells know when and where to divide now have a new tool to study the final fast stage of cell division. The first experiments using this new tool reveal some of the molecular conversation that helps a cell tightly choreograph the time and place of pinching into two cells. In the March 14 Science, researchers from Harvard Medical School (HMS) and colleagues report

In the latest edition of Nature (March 13th, 2003) a group of scientist led by professor Pertti Hari from the University of Helsinki presents a novel observation: ultraviolet radiation induced a flux of nitrogen oxides (NOx) from pine needles to the atmosphere. This result is interesting because nitrogen oxides participate in several essential chemical reactions in the atmosphere. On the other hand, plants can utilize the nitrogen of NOx as their nutrient.

It has been difficult to detect the

Scientists from Imperial College London, the University of Leicester, and Hammersmith Hospital have found a way to stop certain types of genetic diseases from occurring by modifying the way DNA is turned into proteins.

The research published in this month’s Proceedings of the National Academy of Science shows how the researchers have been able to restore proper expression of defective genes, and that this might potentially have a positive effect in genetic diseases such as spinal muscular a

Scientists researching the population numbers of saiga antelope in Russia have found that in the case of the male, there may be a deadly truth in the old boast, ’So many women, so little time.’

Making use of data gathered from a 10-year field study, scientists report in Nature today that saiga antelope, which rank in the World Conservation Union’s category of most endangered species, are being pushed closer to extinction because there are not enough male antelopes to mate with the fe

A recent NASA-funded study has linked the 1991 eruption of the Mount Pinatubo to a strengthening of a climate pattern called the Arctic Oscillation. For two years following the volcanic eruption, the Arctic Oscillation caused winter warming over land areas in the high and middle latitudes of the Northern Hemisphere, despite a cooling effect from volcanic particles that blocked sunlight.

One mission of NASA’s Earth Science Enterprise, which funded this research, is to better understand how th
