Deep inside Great Mountain Forest, in the northwest corner of the state, Yale geophysicist Maureen Long kneels down in a grassy clearing to see how her seismology station fared over the long winter. (more…)
COLUMBIA, Mo. – Lowland South America, including the Amazon Basin, harbors most of the last indigenous societies that have limited contact with the outside world. Studying these tribes, located deep within Amazonian rainforests, gives scientists a glimpse at what tribal cultures may have been like before the arrival of Europeans. Now, researchers at the University of Missouri have used satellite images to assess the demographic health of one particular village of isolated people on the border between Brazil and Peru. Remote surveillance is the only method to safely track uncontacted indigenous societies and may offer information that can improve their chances for long-term survival. (more…)
Research in the Andes examines rock glacier dynamics for mining industry
When it comes to mining for copper and gold, prospectors will move mountains to make it happen. As in, physically dig up the rock, extract the precious metals and move the debris elsewhere.
In the chilly high altitudes of the Andes Mountains, however, what may look like part of a mountain can in fact be a huge, frozen block of rock fragments and ice. When some of that ice melts in the spring, these so-called “rock glaciers” become a valuable source of water for local populations. (more…)
Scientists studying ocean currents and oil spills with large-scale experiment
Scientists are releasing hundreds of floating GPS devices into the Gulf of Mexico this week near the Deepwater Horizon site to study the role of ocean currents in oil spills. The experiment is the largest in scale of its kind, deploying 300 satellite-tracked, untethered buoys, called drifters, over the course of two and a half weeks.
“We’re trying to use the drifters as a simulation of an oil spill,” said Dennis Kirwan, Mary A.S. Lighthipe Professor of Marine Studies in the University of Delaware’s College of Earth, Ocean, and Environment. “This is a big event in oceanography.” (more…)
*Anthropology Helps Us Understand the Past and Allows for a Deeper Understanding of the Future.*
COLUMBIA, Mo. — For more than a century and a half, scientists and tourists have visited massive animal-shaped mounds, such as Serpent Mound in Ohio, created by the indigenous people of North America. But few animal effigy mounds had been found in South America until University of Missouri anthropology professor emeritus Robert Benfer identified numerous earthen animals rising above the coastal plains of Peru, a region already renowned for the Nazca lines, the ruined city of Chan Chan, and other cultural treasures.
“The mounds will draw tourists, one day,” Benfer said. “Some of them are more than 4,000 years old. Compare that to the effigy mounds of North America, which date to between 400 and 1200 AD. The oldest Peruvian mounds were being built at the same time as the pyramids in Egypt.” (more…)
AUSTIN, Texas — A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an already accelerating loss of ice to the sea.
The most extensive record yet of the evolution of the floating ice shelves in the eastern Amundsen Sea Embayment in West Antarctica shows that their margins, where they grip onto rocky bay walls or slower ice masses, are fracturing and retreating inland. As that grip continues to loosen, these already-thinning ice shelves will be even less able to hold back grounded ice upstream, according to glaciologists at The University of Texas at Austin’s Institute for Geophysics (UTIG).

Google is undoubtedly the god of the internet and technology in today’s society. As the number one search engine on the web and the leader in internet and device technology, Google is certainly a force to be reckoned with. Some of the smartest and most creative brains in the industry are working for the tech giant, developing new tools, applications, and websites to further education and access online.
There’s no denying that Google has revolutionized the way in which the internet is used. That being said, Google has also had an immeasurable impact on the world of academics. With endless information right at our fingertips and unbelievable tools available at all times, Google has created tools for learning that in many cases haven’t even been fully realized. These three Google creations are amazing tools that can impact and improve learning and education around the world. (more…)
What’s the best way to study the Antarctic’s ecosystem? Follow the penguins.
Scientists are tracking penguins on land, under the sea, and even from space to unravel the environmental dynamics in the West Antarctic Peninsula as the region experiences climate change.
“We’re not just down there bird watching,” said Matthew Oliver, assistant professor of oceanography in UD’s College of Earth, Ocean, and Environment. “This is a concerted effort to put the whole ecosystem together.” (more…)
