ANN ARBOR — About 50 percent more of the greenhouse gas methane has been seeping into the atmosphere than previously thought, according to far-reaching findings that synthesize two decades’ worth of methane studies in North America.
Methane is the main ingredient in natural gas. (more…)
The eastern Sahara Desert was once home to a 45,000 km2 freshwater lake similar in surface area to the largest in the world today.
A study led by the University of Exeter has revealed that the mega lake was probably formed more than one hundred thousand years ago in the White Nile River Valley in Sudan.
Dr Tim Barrows of the University of Exeter and colleagues used a dating approach based on exposure to cosmic rays to measure the amount of the isotope beryllium-10 in shoreline deposits. Its abundance can be used to calculate how long rocks or sediments have been exposed at the surface of the earth. (more…)
Study finds that human occupation of an area may not contribute to population decline of an endangered species
COLUMBIA, Mo. – Conservation of a protected or endangered species requires frequent monitoring and the dynamic techniques biologists utilize to ensure the survival of threatened animals. Often, scientists study biodiversity at all levels—from genes to entire ecosystems. Currently, researchers at the University of Missouri are employing genotyping to study movement patterns of African forest elephants in protected and unprotected regions of Gabon to better understand how human occupation of these areas might affect elephants on the African continent. Genotyping is helping conservation biologists determine the best course of action to ensure biodiversity and the preservation of various species in the U.S. and abroad. (more…)
Lady Gaga enables followers to embrace their awkwardness while deepening the perceived relationship they feel they have with the celebrity
COLUMBIA, Mo. – According to recent statistics, more than 175 million tweets are sent daily, and 11 accounts are created every second on Twitter. One celebrity who boasts the highest amount of global subscribers is singer Lady Gaga who enjoys more than 40 million Twitter followers. Now, University of Missouri communication researchers have found that online social media gives users an outlet to embrace their differences and provide emotional support to others while deepening perceived relationships they feel they have with celebrities.

UD faculty members discuss 2013 prize-winners at annual symposium
Today’s chemists might work at a computer as often as in a laboratory, medical researchers studying conditions such as diabetes rely on understanding how cells carry and deposit materials within the body, and average investors in the market increasingly buy index funds to average out the short-term ups and downs of individual stocks.
The discoveries that led to these changes are among the work that was honored by this year’s Nobel Prizes. (more…)
Halloween and October Festivities See Six Retail Subcategories in the Top 10
Political News Sites Continue Growth as Americans Keep Tabs on Government Shutdown
RESTON, VA, November 22, 2013 – comScore, Inc., a leader in measuring the digital world, today released its monthly ranking of U.S. desktop web activity at the top online properties for October 2013 based on data from the comScore MMX service. Several retail subcategories were among the top-gaining in October as Halloween and other festivities took place. Americans also frequented Political News sites as major stories such as the U.S. government shutdown and debt ceiling deadline made headlines. (more…)
Two scientists from NASA and NOAA have developed a new space-based technique for monitoring the ice cover of the Great Lakes that is so accurate it can identify a narrow channel of open water cut through the ice by an icebreaker — even at night.
“In the dark, it’s difficult to read a map that’s right in front of you,” said Son Nghiem of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., one of the developers of the new technique. “Yet we now have a way to use satellite radars almost 500 miles [800 kilometers] out in space to see through clouds and darkness and map ice across the Great Lakes.” (more…)
COLUMBIA, Mo. – Meteorologists often use information about warm and cold fronts to determine whether a tornado will occur in a particular area. Now, a University of Missouri researcher has found that the temperature of the Pacific Ocean could help scientists predict the type and location of tornado activity in the U.S.
Laurel McCoy, an atmospheric science graduate student at the MU School of Natural Resources, and Tony Lupo, professor and chair of atmospheric science in the College of Agriculture, Food and Natural Resources, surveyed 56,457 tornado-like events from 1950 to 2011. They found that when surface sea temperatures were warmer than average, the U.S. experienced 20.3 percent more tornados that were rated EF-2 to EF-5 on the Enhanced Fuijta (EF) scale. (The EF scale rates the strength of tornados based on the damage they cause. The scale has six category rankings from zero to five.) (more…)
