Registration is now open for the Mushrooms and Health Summit held at the Mayflower Renaissance hotel in Washington D.C. on September 9-10, 2013. The meeting is of interest to scientists, writers and researchers looking to learn and discuss the unique and comprehensive examination of the global research that links mushrooms to today's and future health issues.
A world-class scientific event
Evaporation is so common that everybody thinks it's a well understood phenomenon. Appearances can be, however, deceptive. Recently, a new, earlier not predicted mechanism of evaporation was discovered. Experiments and simulations performed at the Institute of Physical Chemistry of the Polish Academy of Sciences and the Institute of Physics of the PAS not only confirm its existence, but also indicate that it plays the crucial role in evaporation process in the nanoscale.
Boulder, Colo., USA – Eight new studies posted 26 June and 16 July add to Geosphere's cache of solid research on the nature and structure of North America. Locations studied: Black Canyon of the Gunnison, Colorado; the northern Cascade Mountains, Washington; the Sierra Nevada batholith; the New Jersey shelf; the Appalachian Basin of northwestern Alabama; the Sierra Nevada microplate (Walker Lane rift); and the West Tahoe-Dollar Point fault. A ninth study covers erosion and crustal deformation in central Taiwan.
Polarisability determines the force with which an inhomogeneous external electric field acts on the ions of an ion beam. However, it can be quite tricky to obtain accurate values for this force. Now, two German theoretical chemists, Volker Koch from Bielefeld University and Dirk Andrae from the Free University Berlin, have devised formulas providing the polarisability of atomic ions as a function of their total charge number.
CAMBRIDGE, MA -- It's widely thought that the Earth arose from violent origins: Some 4.5 billion years ago, a maelstrom of gas and dust circled in a massive disc around the sun, gathering in rocky clumps to form asteroids. These asteroids, gaining momentum, whirled around a fledgling solar system, repeatedly smashing into each other to create larger bodies of rubble — the largest of which eventually cooled to form the planets.
CHICAGO – Putting a new spin on the concept of "stress eating," research presented at the 2013 Institute of Food Technologists (IFT) Annual Meeting & Expo® found that people who eat during times of stress typically seek the foods they eat out of habit – regardless of how healthy or unhealthy that food is.
The research co-authored and presented by David Neal, Ph.D., a psychologist and founding partner at Empirica Research, contradicts the conventional wisdom that people who are stressed-out turn to high-calorie, low-nutrient comfort food.
CHICAGO—Healthy snacks that promote a feeling of fullness (satiety) may reduce the amount of food intake at subsequent meals and limit overall food consumption, according to a presentation today at the 2013 Institute of Food Technologists (IFT) Annual Meeting & Food Expo in Chicago®.
Spurred by increasing levels of atmospheric carbon dioxide, forests over the last two decades have become dramatically more efficient in how they use water.
Scientists affiliated with the National Science Foundation's (NSF) Harvard Forest Long-Term Ecological Research (LTER) site report the results in this week's issue of the journal Nature.
Harvard Forest is one of 26 such NSF LTER sites in ecosystems from deserts to grasslands, coral reefs to coastal waters, around the world.
Supraglacial lakes – bodies of water that collect on the surface of the Greenland ice sheet – lubricate the bottom of the sheet when they drain, causing it to flow faster. Differences in how the lakes drain can impact glacial movement's speed and direction, researchers from The City College of New York (CCNY), University of Cambridge and Los Alamos National Laboratory report in "Environmental Research Letters."
Picture two residential beach communities on the New Jersey shore: Bay Head and Mantoloking, which sit side-by-side in Ocean County on a narrow barrier island that separates the Atlantic Ocean and Barnegat Bay.
Before Hurricane Sandy landed on Oct. 29, 2012, a motorist traveling north on Ocean Avenue would seamlessly travel through Mantoloking into Bay Head, noticing few changes in residential development, dunes, beaches, and shoreline.
The difference was hidden under the sand.
Research published in the journal Science (5th July 2013) shows that allowing land use to be determined purely by agricultural markets results in considerable financial and environmental costs to the public. While the research has looked specifically at the UK, the same methods could be applied to any area of the world with similar results for many countries. Land use in most of Europe is dominated by agriculture.
While thermal expansion of the ocean and melting mountain glaciers are the most important factors causing sea-level change today, the Greenland and Antarctic ice sheets will be the dominant contributors within the next two millennia, according to the findings. Half of that rise might come from ice-loss in Antarctica which is currently contributing less than 10 percent to global sea-level rise.
CORVALLIS, Ore. – A new study estimates that global sea levels will rise about 2.3 meters, or more than seven feet, over the next several thousand years for every degree (Celsius) the planet warms.
This international study is one of the first to combine analyses of four major contributors to potential sea level rise into a collective estimate, and compare it with evidence of past sea-level responses to global temperature changes.
Chestnut Hill, MA (July 15, 2013) – Chemists at Boston College and Nagoya University in Japan have synthesized the first example of a new form of carbon, the team reports in the most recent online edition of the journal Nature Chemistry.
Tropical trees and hanging vines burst into flower, showering the ground below with bright blossoms. Temperature, rather than cloud cover, may be key to the timing of tropical flowering events according to research at two sites in the Smithsonian Institution Global Earth Observatory Network published online in Nature Climate Change.
Scientists discovered a significant increase in flower production—about 3 percent more flowers produced on average per year since 1987—on Barro Colorado Island's Forest Dynamics Plot in Panama.
