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
It is not known what genes turn leaves yellow in the fall. However, scientists at Umeå Plant Science Center, Umeå University, and the Royal Institute of Technology in Stockholm (KTH) have managed to identify more than 2,400 genes that take part in the process.
One of the most magnificent pageants of nature every year is when trees take on their autumn colors. Scientists have long known that these colors appear when the green pigment chlorophyll is broken down at the same time as the yellow c
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
