AUGUSTA, Ga. Distinctive patterns of genes turned off or left on in healthy versus cancerous cells could enable early screening for many common cancers and maybe help avoid them, Medical College of Georgia scientists say. Researchers are comparing chemical alterations, called DNA methylatio...Improved air quality during Beijing Olympics could inform pollution-curbing policies
The air in Beijing during the 2008 Olympics was cleaner than the previous year's, due to aggressive efforts by the Chinese government to curtail traffic, increase emissions standards and halt construction in preparation for the games, according to a Cornell study. Led by Max Zhang, assistant pr...Silicon with afterburners: Process developed at Rice could be boon to electronics manufacturer
Scientists at Rice University and North Carolina State University have found a method of attaching molecules to semiconducting silicon that may help manufacturers reach beyond the current limits of Moore's Law as they make microprocessors both smaller and more powerful. Their findings are publi...Stunting plants' skyward reach could lead to improved yields
EAST LANSING, Mich. In the forest's fight for survival, it's the tallest trees that prevail by reaching for sunlight and shading competition. Corn and other plants, too, divert precious energy to grow higher when nearby plants start to encroach. Michigan State University plant scientist Berond...'Invisibility cloak' could protect against earthquakes
LIVERPOOL, UK 20 July 2009: Research at the University of Liverpool has shown it is possible to develop an 'invisibility cloak' to protect buildings from earthquakes.

The study says that government action to reduce sulfur emissions from ...US-Mexico border wall could threaten wildlife species
CORVALLIS, Ore. A 700-mile security wall under construction along the United States' border with Mexico could significantly alter the movement and "connectivity" of wildlife, biologists say, and the animals' potential isolation is a threat to populations of some species. However, technology an...Pacific Northwest forests could store more carbon, help address greenhouse issues
CORVALLIS, Ore. The forests of the Pacific Northwest hold significant potential to increase carbon storage and help mitigate greenhouse gas emissions in coming years, a recent study concludes, if they are managed primarily for that purpose through timber harvest reductions and increased rotation ...New e-science service could accelerate cancer research

AUGUSTA, Ga. Dissecting how heat shock protein 90 gets steroid receptors into shape to use hormones like estrogen and testosterone could lead to targeted therapies for hormone-driven cancers, such as breast and prostate, that need them as well, Medical College of Georgia researchers say. "We ...DNA template could explain evolutionary shifts
HOUSTON (June 21, 2009) Rearrangements of all sizes in genomes, genes and exons can result from a glitch in DNA copying that occurs when the process stalls at a critical point and then shifts to a different genetic template, duplicating and even triplicating genes or just shuffling or deleting p...Fate in fly sensory organ precursor cells could explain human immune disorder
HOUSTON (June 21, 2009) Notch signaling helps determine the fate of a number of different cell types in a variety of organisms, including humans.

Stem cells that respond after a severe injury in the lungs of mice may be a source of rapidly dividing cells that lead to lung cancer, according to a team of American and British researchers. "There are chemically resistant, local-tissue stem cells in the lung that only activate...Identification of genetic variants affecting age at menopause could help improve fertility treatment
Vienna, Austria: For the first time, scientists have been able to identify genetic factors that influence the age at which natural menopause occurs in women. Ms Lisette Stolk, a researcher from Erasmus MC, Rotterdam, The Netherlands, told the annual conference of the European Society of Human ...Gene therapy could expand stem cells' promise
Once placed into a patient's body, stem cells intended to treat or cure a disease could end up wreaking havoc simply because they are no longer under the control of the clinician. But gene therapy has the potential to solve this problem, according to a perspective article from physician-scienti...Wings that waggle could cut aircraft emissions by 20 percent
Wings which redirect air to waggle sideways could cut airline fuel bills by 20% according to research funded by the Engineering and Physical Sciences Research Council (EPSRC) and Airbus in the UK.

Combi...Plants could override climate change effects on wildfires
The increase in warmer and drier climates predicted to occur under climate change scenarios has led many scientists to also predict a global increase in the number of wildfires. But a new study in the May issue of Ecological Monographs shows that in some cases, changes in the types of plants gro...New nucleotide could revolutionize epigenetics
Anyone who studied a little genetics in high school has heard of adenine, thymine, guanine and cytosine the A,T,G and C that make up the DNA code. But those are not the whole story. The rise of epigenetics in the past decade has drawn attention to a fifth nucleotide, 5-methylcytosine (5-mC), that...
