Glaucoma is the second leading cause of blindness. Nearly 4 million Americans have the disorder, which affects 70 million worldwide. There is no cure and no early symptoms. Once vision is lost, it's permanent.
New findings at Georgia Tech, published in January during Glaucoma Awareness Month, explore one of the many molecular origins of glaucoma and advance research dedicated to fighting the disease.
It could be called the wingman theory or the Barney Stinson principle (after the character played by Neil Patrick Harris on hit TV show How I Met Your Mother). A University of Alberta researcher says that – like Barney, who spends much of his time trying to find his single friend a mate – people are generally willing to help a friend protect or enhance his reputation or help him otherwise save face in a social situation.
Researchers have devised a proposal for the first conclusive experimental test of a phenomenon known as 'Bell's nonlocality.' This test is designed to reveal correlations that are stronger than any classical correlations, and do so between high-energy particles that do not consist of ordinary matter and light. These results are relevant to the so-called 'CP violation' principle, which is used to explain the dominance of matter over antimatter.
There is an increasing trend towards nimbyism -- people welcome developments in principle, so long as they are "not in my backyard." But just how big is a backyard? The answer depends on a number of factors and Guenther Schauberger of the University of Veterinary Medicine, has now developed a mathematical model to calculate appropriate distances from residential areas for livestock building to be sited. The model is published in the journal Atmospheric Environment.
Nitrogen is both an essential nutrient and a pollutant, a byproduct of fossil fuel combustion and a fertilizer that feeds billions, a benefit and a hazard, depending on form, location, and quantity. Agriculture, industry and transportation have spread nitrogen liberally around the planet, say sixteen scientists in the latest edition of ESA's Issues in Ecology series, "Excess Nitrogen in the U.S.
New research has found that individuals and the private sector have an important role to play in the provision of public policies to help society adapt to the impacts of climate change.
Writing in the journal Global Environmental Change, Dr Emma Tompkins and Hallie Eakin from the University of Southampton, say that public investments alone cannot reduce our vulnerability to climate change.
LIVERMORE, Calif. -- In a breakthrough paper published in this week's issue of Science magazine, researchers from Sandia's Combustion Research Facility, the University of Manchester and Bristol University report direct measurements of reactions of a gas-phase Criegee intermediate using photoionization mass spectrometry. (visit www.youtube.com/SandiaLabs to see a short video of Sandia combustion chemists discussing the research.)
Scientists have offered up a convincing explanation for the harsh winters recently experienced in the Northern Hemisphere; increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn months at lower latitudes.
Their findings may throw light on specific weather incidents such as the extremely harsh Florida winter of 2010 which ended up killing a host of tropical creatures, as well as the chaos-causing snow that fell on the UK in December 2010.
Quick, come up with an imaginary co-worker.
Did you imagine someone who is positive, confident, and resourceful? Who rises to the occasion in times of trouble? If so, then chances are that you also display those traits in your own life, a new study finds.
University of Nebraska-Lincoln researchers have found that study participants who conjured positive imaginary co-workers contributed more in the actual workplace, both in job performance and going above and beyond their job descriptions to help others.
Preserving diverse plant life will be crucial to buffer the negative effects of climate change and desertification in in the world's drylands, according to a new landmark study.
The findings of the multi-author study, published today in the journal Science, are based on samples of ecosystems in every continent except Antarctica.
They confirm for the first time that the more diverse an ecosystem is, the more ecological functions it performs. It also has implications for carbon sequestration and soil health.
In a breakthrough paper published in Science, researchers from The University of Manchester, The University of Bristol and Sandia National Laboratories report the potentially revolutionary effects of Criegee biradicals.
These invisible chemical intermediates are powerful oxidisers of pollutants such as nitrogen dioxide and sulfur dioxide, produced by combustion, and can naturally clean up the atmosphere.
DURHAM, N.C. -- While physicists at the Large Hadron Collider smash together thousands of protons and other particles to see what matter is made of, they're never going to hurl electrons at each other. No matter how high the energy, the little negative particles won't break apart. But that doesn't mean they are indestructible.
Polymer nano-films and nano-composites are used in a wide variety of applications from food packaging to sports equipment to automotive and aerospace applications. Thermal analysis is routinely used to analyze materials for these applications, but the growing trend to use nanostructured materials has made bulk techniques insufficient.
