Record-Breaking Slide Would Bury Central Park 66 Feet Deep
Last year’s gigantic landslide at a Utah copper mine probably was the biggest nonvolcanic slide in North America’s modern history, and included two rock avalanches that happened 90 minutes apart and surprisingly triggered 16 small earthquakes, University of Utah scientists discovered.
The landslide – which moved at an average of almost 70 mph and reached estimated speeds of at least 100 mph – left a deposit so large it “would cover New York’s Central Park with about 20 meters (66 feet) of debris,” the researchers report in the January 2014 cover study in the Geological Society of America magazine GSA Today.

This year’s unusually long and rocky flu season would be nothing compared to the pandemic that could occur if bird flu became highly contagious among humans, which is why UCLA researchers and their colleagues are creating new ways to predict where an outbreak could emerge.
“Using surveillance of influenza cases in humans and birds, we’ve come up with a technique to predict sites where these viruses could mix and generate a future pandemic,” said lead author Trevon Fuller, a UCLA postdoctoral research fellow at the Institute of the Environment and Sustainability’s Center for Tropical Research.

Former U.N. secretary-general Kofi Annan predicted during a campus visit that the civil war in Syria will become even more tragic before the international community takes action to help resolve the conflict, but said he is optimistic about the political and economic prospects for Africa in the years ahead.

Taking into consideration its size, an ancient relative of piranhas weighing about 20 pounds delivered a bite with a force more fierce than prehistoric whale-eating sharks, the four-ton ocean-dwelling Dunkleosteus terrelli and – even – Tyrannosaurus rex.
Besides the force of the bite, Megapiranha paranensis appears to have had teeth capable of shearing through soft tissue the way today’s piranhas do, while also being able to pierce thick shells and crack armoring and bones, according to Stephanie Crofts, a University of Washington doctoral student in biology.

Winners of the second annual Imagine Cup Grants program, part of Microsoft’s YouthSpark initiative, include student startups aiming to eliminate traffic jams and bring cheap, effective ways to diagnose childhood pneumonia.
MOUNTAIN VIEW, Calif. — Dec. 4, 2012 — Traffic jams typically produce little more than frustration, profanity, and CO2. Four years ago, though, they happened to give Christian Brüggeman an idea.
He was sitting in a London Starbucks with a friend and fellow computer science student. As they chatted, they noticed that one street outside was choked with cars while another was practically empty.
They wondered why drivers weren’t taking advantage of every possible route. If cars could be directed along less-congested roads, wouldn’t that prevent back-ups before they began? (more…)
Egypt’s new democratically elected president Mohamed Morsi recently made world headlines on two accounts. The first was for his central role in brokering a cease-fire in Gaza between Israeli forces and Hamas. The second, which followed almost immediately after the deal was confirmed, was a highly controversial presidential decree that would temporarily insulate his legislative and executive decisions from any judicial oversight. Ian Straughn, visiting assistant professor of anthropology and Joukowsky Family Librarian for Middle East Studies, analyzes the return of protesters to Cairo’s Tahrir Square and the future of the Arab Spring in Egypt.

EAST LANSING, Mich. — Foreign policy has taken center stage in the presidential campaign as Barack Obama and Mitt Romney tout their differing plans – and take aim at one another’s vision for international security.
Unfortunately, voters pay little attention to these issues when electing a president, said Matt Zierler, associate professor of international relations at Michigan State University’s James Madison College.
“Foreign policy does matter, but voters traditionally don’t pay much attention to it,” Zierler said. (more…)
Ancient pollen and charcoal preserved in deeply buried sediments in Egypt’s Nile Delta document the region’s ancient droughts and fires, including a huge drought 4,200 years ago associated with the demise of Egypt’s Old Kingdom, the era known as the pyramid-building time.
“Humans have a long history of having to deal with climate change,” said Christopher Bernhardt, a researcher with the U.S. Geological Survey. “Along with other research, this study geologically reveals that the evolution of societies is sometimes tied to climate variability at all scales – whether decadal or millennial.” (more…)
