  • TORONTO — Computations requiring high performance computing (HPC) power may soon be done in the palm of your hand thanks to work done this summer by IBM Research in Dublin, Ireland.  [...]

    HPC is normally essential to resolve the differential equations that encapsulate these physical processes and their relationships, and the expense often limits the spatial resolution, physical processes and time-scales that can be investigated by a real-time forecasting platform. In an interview with EE Times, IBM Research Senior Research Manager Sean McKenna said an HPC cluster using Big Iron has generally been the solution to dealing with the heavy computational load. IBM Research wanted to see if it could do the same work more quickly and more simply, he said.

  • Wildfire is an ever-present reality for many communities in the Western United States. As the West’s fires burn longer and hotter, some politicians have taken to scapegoating the region’s public lands, alleging that wildfire is worse on U.S. public lands than state-owned lands. Their claim, according to a new analysis of wildfire risk in the West, is entirely untrue. It’s time for public officials to abandon their baseless rhetoric and engage in pragmatic conversations and policy development to protect Western communities from wildfire risks.

  • HANOVER, N.H. – James Holder, head coach of the men’s and women’s swimming and diving teams, has announced the hiring of Milana Socha as an assistant coach ahead of the 2017-18 season. Socha comes to Hanover from the University of Toledo, where she served as an assistant last season. 

    “We are extremely excited to welcome Milana to our staff,” Holder said. “She distinguished herself in our search process with her knowledge and passion for the sport. She has experience working with athletes that are both high-end academics as well as top athletes, which is the balance we strike here at Dartmouth. I couldn’t be happier to welcome her to our program and look forward to working with her.”

  • This September is Eat Local Month – an event specific not only to Bellingham, but to all of Whatcom County. Sustainable Connections, the local nonprofit that orchestrates Eat Local Month, works with farmers, restaurateurs, food businesses and fishermen to help bring all together to honor and celebrate the amazing food Whatcom County has to offer. [...]

    Sophie Williams of Raven Breads says the reason she is in business is to make the best product she can, add substantially to her community and cause as little harm as she can to both people and the environment. “Using local [and regional] ingredients from farmers and producers I know is the only way I can fulfill all three of these objectives,” Williams says.

    In addition to using ingredients from local farmers and producers herself, other vendors and producers also use the bread Williams makes in their food. Cafe Vavilov uses whole grain bread from Raven Breads in their Vegan Farmers dish. The cafe, run by Erica Budzynski incorporates a slew of locally sourced and grown ingredients in their meals, and has a booth set up at the farmers market on Saturdays, during which they use enamel plates to serve food and cut down on waste.

  • LAWRENCE, KANSAS -- Most researchers dedicate grant funds to things like lab equipment, travel expenses or salaries for graduate assistants. But not too long ago, University of Kansas geologist Leigh Stearns found herself at a Cabela's, grant in hand, asking the gun-counter staff which rifle might be most suitable for defending herself from a polar bear.

    "I got a Marlin Model 1895 Big Bore Lever-Action Rifle," she said. "I took private lessons. Then I went to KU Public Safety office, and they actually took me to the KU police range and helped show me how to shoot." [...]

    "You can think of Greenland as a big reservoir of ice that has around 200 glaciers draining it. However, there are only a handful of glaciers responsible for most of its mass loss. Helheim is one of them -- its annual mass loss doubled since 2001, but not in a linear or easily understandable way. Because Helheim Glacier discharges a lot of ice each year, we are very interested in understanding what controls its behavior."

    While one ATLAS system has been in place already since 2015, a continuing $569,000, three-year grant from the Heising-Simons Foundation will enable Stearns, along with a KU graduate student and researchers from the U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory (CRREL), to install a second system. Stearns expects the new ATLAS station to deliver even more comprehensive data on ice dynamics and the glacier's response to atmospheric and ocean variability.

    Jessica Tetreault and I were the only two middle school teachers at a recent conference, so we were paired to create a common performance assessment that we could both use with our students in the coming months. She volunteered to share an assessment on gravity that her students recently completed, as I was about to start my unit on gravity and scale in the universe. I didn’t know it then, but collaborating with Jess would improve the entire instructional sequence, not just the performance assessment. Working with Jess made planning easier, enjoyable, and more effective.

    Jess explained her performance assessment. After discovering what their weight would be on different planets, students choose three planets to focus on: Earth, a planet they weigh less on, and a planet they weigh more on. Then they create scale, paper models of three planets. Finally, they write an explanation for why their weight changes using claim, evidence, and reasoning.

  • Geoscientists at the University of Arizona will combine multiple disciplines to study the fluids beneath the Earth's surface with the help of a $1 million grant from the W.M. Keck Foundation.

    Subsurface fluids such as oil, gas, deep brine and shallow groundwater move large amounts of heat and solutes (dissolved substances) through the crust as they chemically and physically alter rocks. Figuring out how these fluids interact with subsurface rocks is important not only for understanding critical energy and mineral resources but also for effective management of energy byproducts such as wastewater, carbon dioxide and spent nuclear fuel.

    With the three-year grant from the Keck Foundation, UA researchers will integrate geologic, geochemical, geochronologic and hydrogeologic observations and develop an integrated, interdisciplinary understanding of subsurface fluid-rock systems. Prior to this, most approaches to studying subsurface interactions looked at only parts of the system in isolation.

    "Our goal is to understand when and how different paleofluids were generated, how they moved, interacted with and altered rocks, and what this says about the geologic history of the region," said UA geosciences professor Peter Reiners, who is leading the team. Paleofluids are those fluids that have been present over a period of time in the past.

  • Not to get all hipster about it, but you probably haven’t heard of one of the most impressive Ice Age treasure troves in the country. Don’t fret. I’m not going to keep it a secret. It’s a place you could make tracks for right now if you wanted to, tucked away in southern California between LA and San Diego. The official name is the Western Science Center, built on the edge of Diamond Valley Lake in Hemet, but, to a group of paleontologists, artists, writers, and poets who gathered there earlier this month, it’s also known as the Valley of the Mastodons.

    American mastodon fossils have been found from New Jersey to the Channel Islands, from the Yukon to Florida. But in the collections of the Western Science Center – uncovered, as geologist Kathleen Springer explained, during a seven-year paleontological rescue missionspurred by the construction of Diamond Valley Lake – holds an impressive number of the Ice Age beasts. More than that, the Mammut americanum found here – like Max, Lil’ Stevie, and Blaze, to name just a few of the more charismatic specimens – are different from those found elsewhere in California, not to mention the rest of the continent. That’s what led to this unconventional assemblage of conference attendees, hand-picked by paleontologists Alton Dooley and Katy Smith.

  • Dr. Carl Tape is an associate professor of geophysics at UAF at the Geophysical Institute and the Department of Geosciences. He is conducting research on seismic tomography and seismic wave propagation. Seismic tomography is a technique for imaging the subsurface of the Earth with seismic waves produced by earthquakes or explosions. Seismic waves travel through the Earth’s layers, and originate from earthquakes, volcanic eruptions, magma movement, large landslides or large man-made explosions that give out low-frequency acoustic energy. Dr. Tape is leading research efforts in Alaska with the goal of developing a 3D model of the subsurface crust and upper mantle.
