A team of researchers led by Virginia Tech and University of California, Berkeley, scientists has discovered that a regulatory process that turns on photosynthesis in plants at daybreak likely developed on Earth in ancient microbes 2.5 billion years ago, long before oxygen became available. The research opens new scientific areas in the fields of evolutionary biology and microbiology. The work also has broad societal implications as it allows scientists to better understand the production...

Protein controls editing, expanding the information content of DNA An international team of researchers, led by scientists from the University of California, San Diego School of Medicine and Indiana University, have identified a protein that broadly regulates how genetic information transcribed from DNA to messenger RNA (mRNA) is processed and ultimately translated into the myriad of proteins necessary for life. The findings, published today in the journal Cell Reports, help explain how...

Most Women Should Get A Mammogram Every Two Years
2014-02-04 10:38:20

Elizabeth Fernandez - University of California - San Francisco Study led by UCSF breast cancer expert recommends screening guidelines developed by US Preventive Services Task Force Adoption of new guidelines recommending screening mammography every two years for women ages 50 to 74 would result in breast cancer screening that is equally effective, while saving the United States $4.3 billion a year in health care costs, according to a study led by UC San Francisco. The study...

New Technique Turns Plant Waste Into Biogasoline
2014-02-04 07:17:39

University of California, Davis Gasoline-like fuels can be made from cellulosic materials such as farm and forestry waste using a new process invented by chemists at the University of California, Davis. The process could open up new markets for plant-based fuels, beyond existing diesel substitutes. "What's exciting is that there are lots of processes to make linear hydrocarbons, but until now nobody has been able to make branched hydrocarbons with volatility in the gasoline range," said...

Protein Critical To Hematopoietic Stem Cell Function And Blood Formation Identified
2014-02-03 08:09:16

University of California - San Diego Researchers at the University of California, San Diego School of Medicine have identified a protein critical to hematopoietic stem cell function and blood formation. The finding has potential as a new target for treating leukemia because cancer stem cells rely upon the same protein to regulate and sustain their growth. Hematopoietic stem cells give rise to all other blood cells. Writing in the February 2, 2014 advance online issue of Nature Genetics,...

NERSC Turns On Switch For 'Edison'
2014-01-30 15:07:07

NERSC The National Energy Research Scientific Computing (NERSC) Center recently accepted “Edison,” a new flagship supercomputer designed for scientific productivity. Named in honor of American inventor Thomas Alva Edison, the Cray XC30 will be dedicated in a ceremony held at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) on Feb. 5, and scientists are already reporting results. About 5,000 researchers working on 700 projects and running 600...

New Virus From Africa Kills Anthrax Agent
2014-01-28 08:57:55

Andy Fell - University of California - Davis From a zebra carcass on the plains of Namibia in Southern Africa, an international team of researchers has discovered a new, unusually large virus (or bacteriophage) that infects the bacterium that causes anthrax. The novel bacteriophage could eventually open up new ways to detect, treat or decontaminate the anthrax bacillus and its relatives that cause food poisoning. The work is published Jan. 27 in the journal PLOS One. The virus was...

[ Watch the Video: What Could Be Raining Down Life In Our Solar System? ] redOrbit Staff & Wire Reports - Your Universe Online Dust that originates from comets, asteroids and leftover debris from the birth of the Solar System could deliver water and organic material to the Earth and other terrestrial planets, according to a recent Proceedings of the National Academy of Science paper. In the study, researchers from the University of Hawaii-Manoa (UHM) School of Ocean and Earth...

A team of scientists, led by principal investigator David D. Schlaepfer, PhD, a professor in the Department of Reproductive Medicine at the University of California, San Diego School of Medicine, has found that a protein involved in promoting tumor growth and survival is also activated in surrounding blood vessels, enabling cancer cells to spread into the bloodstream. The findings are published in this week's online issue of the Journal of Cell Biology. Blood vessels are tightly lined...

Results From Icelandic Deep Drilling Project Highlighted In This Months Issue Of Geothermics
2014-01-24 09:12:23

Iqbal Pittalwala - University of California - Riverside In 2009, a borehole drilled at Krafla, northeast Iceland, as part of the Icelandic Deep Drilling Project (IDDP), unexpectedly penetrated into magma (molten rock) at only 2100 meters depth, with a temperature of 900-1000 C. The borehole, IDDP-1, was the first in a series of wells being drilled by the IDDP in Iceland in the search for high-temperature geothermal resources. The January 2014 issue of the international journal...
