Between 24 and 26 February, a number of trial flights into Dakar using the EGNOS (European Global Navigation Overlay Service) Test Bed system were carried out to show how the planned provision of Global Navigation Satellite System (GNSS) services over Central Africa could be implemented.

ASECNA (Agence pour la sécurité de la navigation aérienne en ASECNA (Agence pour la SECurité de la Navigation Aérienne en Afrique et à Madagascar) has worked with the European Space Agency, the European Com

In what is a first for biology, a team of investigators at The Scripps Research Institute (TSRI) is reporting that the human body makes ozone.

Led by TSRI President Richard Lerner, Ph.D. and Associate Professor in the Department of Chemistry Paul Wentworth, Jr, Ph.D., who made the original discovery, the team has been slowly gathering evidence over the last few years that the human body produces the reactive gas—most famous as the ultraviolet ray-absorbing component of the ozone layer—as p

Research is key step in detoxifying endosulfan toward improving soil and water quality

Scientists at the University of California, Riverside report in the Journal of Environmental Quality (JEQ) that they have isolated microorganisms capable of degrading endosulfan, a chlorinated insecticide widely used all over the world and which is currently registered to control insects and mites on 60 U.S. crops. JEQ, established in 1972, is published jointly by the American Society of Agronomy,

Dartmouth Medical School geneticists studying the biological clock have opened yet another window into the role of an unusual form of RNA known as antisense that blocks the messages of protein-encoding genes.

They found that antisense RNA appears to regulate core timing genes in the circadaian clock that drives the 24-hour light-dark cycle of Neurospora, a model organism better known as bread mold.

The results are reported in the February 27 Nature by Drs. Jennifer Loros and Jay C.

Scientists with the U.S. Department of Energy’s Joint Genome Institute (JGI) and the Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a powerful new technique for deciphering biological information encoded in the human genome. Called “phylogenetic shadowing,” this technique enables scientists to make meaningful comparisons between DNA sequences in the human genome and sequences in the genomes of apes, monkeys, and other non-human primates. With phylogenetic shadowing, scientists c

For the first time, scientists have identified and analyzed single grains of silicate stardust in the laboratory. This breakthrough, to be reported in the Feb. 27 issue of Science Express, provides a new way to study the history of the universe.
“Astronomers have been studying stardust through telescopes for decades,” said first author Scott Messenger, Ph.D., senior research scientist in the Laboratory for Space Sciences at Washington University in St. Louis. “And they have derived models of wha
