Findings suggest hunting with stone-tipped spears began much earlier than previously believed
TORONTO, ON – A University of Toronto-led team of anthropologists has found evidence that human ancestors used stone-tipped weapons for hunting 500,000 years ago – 200,000 years earlier than previously thought. (more…)
Renowned geoscientist Richard Alley shares climate history, predictions
Richard Alley, Evan Pugh Professor of Geosciences at Pennsylvania State University, appeared at the University of Delaware’s Mitchell Hall on Nov. 8 to discuss his breakthrough findings about abrupt climate changes in Earth’s past and the implications of his research for Earth’s future. (more…)
EAST LANSING, Mich. — A team of Michigan State University researchers will soon be heading into the rainforests of Nicaragua to help an endangered species known as a Baird’s tapir co-exist with local farmers whose crops are being threatened by the animals. (more…)
Japan fisheries data provides a look at how the ocean is faring 18 months after the worst accidental release of radiation to the ocean in history
Japan’s “triple disaster,” as it has become known, began on March 11, 2011, and remains unprecedented in its scope and complexity. To understand the lingering effects and potential public health implications of that chain of events, scientists are turning to a diverse and widespread sentinel in the world’s ocean: fish.
Events on March 11 began with a magnitude 9.0 earthquake, the fourth largest ever recorded. The earthquake in turn spawned a massive 40-foot tsunami that inundated the northeast Japanese coast and resulted in an estimated 20,000 missing or dead. Finally, the wave caused catastrophic damage to the Fukushima Dai-ichi nuclear power plant, resulting in the largest accidental release of radiation to the ocean in history, 80 percent of which ended up in the Northwest Pacific Ocean.

EAST LANSING, Mich. — The job market for new college graduates, hampered by a lackluster economy and political uncertainty, will increase at a sluggish 3 percent this academic year, predicts Michigan State University’s annual Recruiting Trends report. (more…)
UD researchers studying ‘fingerprint’ left on seafloor by Hurricane Sandy
Beneath the 20-foot waves that crested off Delaware’s coast during Hurricane Sandy, thrashing waters reshaped the floor of the ocean, churning up fine sand and digging deep ripples into the seabed. Fish, crustaceans and other marine life were blasted with sand as the storm sculpted new surfaces underwater. (more…)
Berkeley Lab Researchers Combine Old Fermentation Process For Making Explosives with New Chemical Catalysis to Boost Biofuel Production
A fermentation technique once used to make cordite, the explosive propellant that replaced gunpowder in bullets and artillery shells, may find an important new use in the production of advanced biofuels. With the addition of a metal catalyst, researchers at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the production of acetone, butanol and ethanol from lignocellulosic biomass could be selectively upgraded to the high volume production of gasoline, diesel or jet fuel.

Students in Mitchell Pavao-Zuckerman’s UA ecology class took to the streets of Tucson last week to lend their eyes and minds to real science.
You might have looked out your kitchen window last week to see a group of college students standing on the sidewalk clutching notepads and contemplating your front yard. If so, don’t worry – they were likely just counting the shrubbery. (more…)
