Just like old times: Generating RNA molecules in water
A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors. view more (2009-11-23)
New paper describes connections between Circadian and metabolic systems
A paper by University of Notre Dame biologist Giles Duffield and a team of researchers offers new insights into a gene that plays a key role in modulating the body's Circadian system and may also simultaneously modulate its metabolic system. view more (2009-11-13)
Darwin meets Facebook
Natural history plans to chart life on earth, yet the discipline risks being buried under a landslide of painstakingly collected data that isn't always used. view more (2009-11-10)
UCSD discovery allows scientists for the first time to experimentally annotate genomes
Over the last 20 years, the sequencing of the human genome, along with related organisms, has represented one of the largest scientific endeavors in the history of mankind. view more (2009-11-10)
Nitrogen loss threatens desert plant life, study shows
As the climate gets warmer, arid soils lose nitrogen as gas, reports a new Cornell study. That could lead to deserts with even less plant life than they sustain today, say the researchers. view more (2009-11-09)
Contracts foster trust, but flexibility is needed, research says
While detailed contracts can foster trust between parties, there needs to be flexibility in negotiating potential changes, according to research recently published in MIS Quarterly. view more (2009-11-02)
Spider web glue spins society toward new biobased adhesives
With would-be goblins and ghosts set to drape those huge fake spider webs over doorways and trees for Halloween, scientists in Wyoming are reporting on a long-standing mystery about real spider webs: It is the secret of spider web glue. view more (2009-10-22)
Installed cost of solar photovoltaic systems in the US fell in 2008
Researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) released a new study on the installed costs of solar photovoltaic (PV) power systems in the U.S., showing that the average cost of these systems declined by more than 30 percent from 1998 to 2008. Within the last year of this period, costs fell by more... view more... (2009-10-22)
Getting on 'the GABA receptor shuttle' to treat anxiety disorders
There are increasingly precise molecular insights into ways that stress exposure leads to fear and through which fear extinction resolves these fear states. view more (2009-10-22)
Accelerated bone growth may be an indicator of hypertension in children
Children whose bones are "older" than their chronological age may be at an increased risk of hypertension, according to a study reported today (19 October) in Hypertension: Journal of the American Heart Association. view more (2009-10-21)
Protein interaction network can respond Helicobacter pylori infection?
Helicobacter pylori (H pylori) is a gram negative bacterium which infects about 50% of the world population. H pylori colonization causes a strong systemic immune response. view more (2009-10-16)
Carnegie Mellon researchers save electricity with low-power processors and flash memory
Researchers at Carnegie Mellon University and Intel Labs Pittsburgh (ILP) have combined low-power, embedded processors typically used in netbooks with flash memory to create a server architecture that is fast, but far more energy efficient for data-intensive applications than the systems now used by major Internet services. view more (2009-10-15)
National Science Foundation awards grants for studies of coupled natural and human systems
How do humans and their environment interact, and how can we use knowledge of these links to adapt to a planet undergoing radical climate and other environmental changes? view more (2009-10-15)
Developing enzymes to clean up pollution by explosives
Scientists at the University of York have uncovered the structure of an unusual enzyme which can be used to reverse the contamination of land by explosives. view more (2009-10-09)
ACPM recommends primary care have systems in place for screening and treating depression
The American College of Preventive Medicine (ACPM) supports the recommendations of the US Preventive Services Task Force (USPSTF) that primary care providers should screen all adults for depression, and further recommends that all primary care providers should have systems in place to ensure the accurate diagnosis and treatment of this condition. view more (2009-10-07)
Color sensors for better vision
The car of the future will have lots of smart assistants onboard - helping to park the car, recognize traffic signs and to warn the driver of blind spot hazards. view more (2009-10-06)
Less than half of medical students understand health care system
Less than half of graduating medical students in the U.S. say they received adequate training in understanding health care systems and the economics of practicing medicine. view more (2009-10-01)
New discovery reveals fate of nanoparticles in human cells
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have uncovered what happens to biomimetic nanoparticles when they enter human cells. view more (2009-09-23)
Echoes of phlogiston in stem cell biology
Before it was learned that matter burns by taking up oxygen, most chemists sought to explain combustion as the release of a mysterious substance, which they named "phlogiston". view more (2009-09-22)
Bugs in Boxes Shed Light on Biological Invasions
Bugs in boxes are helping UC Davis researcher Alan Hastings improve scientific tools used to predict the spread of invasive plants and animals. view more (2009-09-21)
