"Scientists have speculated that such a large mountain range must have been feeding the oceans because of the way life thrived and ocean chemistry changed at this time, and finally we have found it."
The discovery is earliest evidence of Himalayan-scale mountains on Earth.
"Although the mountains have long since washed away, rocks from their roots told the story of the ancient mountain range's grandeur," said co-researcher Professor Joerg Hermann.
Pre-eclampsia, the potentially deadly condition that affects pregnant women, may be caused by problems meeting the oxygen demands of the growing fetus, according to an editorial in the November issue of Anaesthesia, the journal of the Association of Anaesthetists of Great Britain and Ireland (AAGBI).
PULLMAN, Wash. – Washington State University researchers have developed a new catalyst that could lead to making biofuels cheaply and more efficiently.
Led by Voiland Distinguished Professor Yong Wang, the researchers mixed inexpensive iron with a tiny amount of rare palladium to make the catalyst. Their work is featured on the cover of the October issue of the journal ACS Catalysis.
Removing oxygen for better fuel
New York, NY—October 15, 2014—Researchers from Columbia Engineering and the Georgia Institute of Technology report today that they have made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2), resulting in a unique electric generator and mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.
Next year, the European Commission is set to release guidelines for warning labels on products made with lavender oil, which reportedly can cause allergic reactions for some people. But lavender growers in France are putting up a fight, and some are even threatening to quit the business altogether if the rules go into effect, according to an article in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society.
A University of Cincinnati research project is taking a groundbreaking approach to monitoring groundwater resources near fracking sites in Ohio. Claire Botner, a UC graduate student in geology, will outline the project at The Geological Society of America's Annual Meeting & Exposition. The meeting takes place Oct. 19-22, in Vancouver.
Montreal, October 14, 2014 – High doses of fish oil supplements, rich in omega-3 fatty acids, do not reduce atrial fibrillation, a common type of irregular heartbeat in which the heart can beat as fast as 150 beats a minute. The results of the AFFORD trial led by the Montreal Heart Institute were published in the Journal of the American College of Cardiology on October 7th.
Almost exactly three years ago, the United Nations called on governments and industry to ensure that the world's population would have access to broadband Internet by 2015.
Broadband, a relatively fast and always-on Internet connection service, is one of the most economically significant and fastest growing sectors of the Internet.
URBANA, Ill. – For about a decade, Chinese consumers weren't getting what they paid for when they purchased Wuchang, a special brand of gourmet rice that has a peculiar scent. The quality was being diluted when less expensive rice was aromatized, added to the packages of the high-quality rice, and sold at the premium price. Researchers at the University of Illinois studied how the tampering scandal affected the public's perception of risk and their subsequent behavior.
Interactions between health care professionals and the prescription drug and medical device industries are common in the United States, especially in academic medical centers, and may include gifts to medical students such as textbooks and interactions of marketing representatives with students. Such practices have been criticized as potentially conveying biased information and reducing the students' skepticism about potentially misleading claims.
Swedish and Chinese researchers show how a unique nano-alloy composed of palladium nano-islands embedded in tungsten nanoparticles creates a new type of catalysts for highly efficient oxygen reduction, the most important reaction in hydrogen fuel cells. Their results are published in the scientific journal Nature Communications.
LAWRENCE — Few people devote time to pondering the ancient origins of the eel-like lamprey, yet the evolutionary saga of the bloodsucker holds essential clues to the biological roots of humanity.
Today, the Proceedings of the National Academy of Sciences published a description of fossilized lamprey larvae that date back to the Lower Cretaceous — at least 65 million years ago.
They're the oldest identified fossils displaying the creature in stages of pre-metamorphosis and metamorphosis.
Washington D.C., October 14, 2014 -- Even as the 2014 Nobel Prize in Physics has enshrined light emitting diodes (LEDs) as the single most significant and disruptive energy-efficient lighting solution of today, scientists around the world continue unabated to search for the even-better-bulbs of tomorrow.
Enter carbon electronics.
Scientists from Nanyang Technological University (NTU Singapore) have developed a new battery that can be recharged up to 70 per cent in only 2 minutes. The battery will also have a longer lifespan of over 20 years.
Expected to be the next big thing in battery technology, this breakthrough has a wide-ranging impact on many industries, especially for electric vehicles which are currently inhibited by long recharge times of over 4 hours and the limited lifespan of batteries.
WASHINGTON, Oct. 13, 2014 — Whether it's a plain cheese, a deep-dish stacked with meats or a thin-crust veggie delight, there's just something about pizza that makes it delicious. There's a lot of chemistry that goes into everything from dough to sauce to toppings to, of course, cheese. There's also a very specific chemical reaction at work on every single slice, no matter what toppings you choose.
