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…)

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…)

Epidemiology and gene sequencing technologies have been used by researchers in the UK, the Kingdom of Saudi Arabia, the US and Canada to show that the novel Middle East Respiratory Syndrome (MERS) coronavirus can spread between people in healthcare settings. The work is published in the New England Journal of Medicine.
The scientists, from the Saudi Arabian Ministry of Health, UCL, Wellcome Trust Sanger Institute, University of Toronto, University of Colorado and Johns Hopkins University, rapidly investigated and defined the epidemiology, transmission dynamics and genetic composition of the MERS-CoV cluster of 22 cases of healthcare-acquired MERS coronavirus infections from a recent outbreak in Al-Hasa, Eastern Province, Kingdom of Saudi Arabia.
