Small and Medium Enterprises Enter the Limelight

November 14, 2014 11:43 am | by Steve Conway | Articles | Comments

A decade of close scrutiny has shed much more light on the technical computing needs of small and medium enterprises (SMEs), but they are still shrouded in partial darkness. That’s hardly surprising for a diverse global group with millions of members ranging from automotive suppliers and shotgun genomics labs to corner newsstands and strip mall nail salons.

A reliable way of predicting the flow of traffic could be a great convenience for commuters, as well as a significant energy-saver. During an emergency evacuation following a natural disaster, reliable predictions of the best routes could even be a lifesaver. Now a team of researchers from MIT, the University of Notre Dame, and elsewhere has devised what they say is an effective and relatively simple formula for making such predictions.

Time Machine Reveals Global Precipitation Role in Major Weather Events

October 16, 2014 2:53 pm | by Michael Price, San Diego State University | News | Comments

During the 1930s, North America endured the Dust Bowl, a prolonged era of dryness that withered crops and dramatically altered where the population settled. Land-based precipitation records from the years leading up to the Dust Bowl are consistent with the telltale drying-out period associated with a persistent dry weather pattern, but they can’t explain why the drought was so pronounced and long-lasting.

Shocking Results: Few Data, Urgent Need for more Arctic Carbon Measurements

October 13, 2014 12:32 pm | by Carol Rasmussen, NASA | News | Comments

As climate change grips the Arctic, how much carbon is leaving its thawing soil and adding to Earth's greenhouse effect? The question has long been debated by scientists. A new study conducted as part of NASA's Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) shows just how much work still needs to be done to reach a conclusion on this and other basic questions about the region where global warming is hitting hardest.

Technology is putting complex topics like severe weather and climate change on the map — literally. Mapping data associated with specific geographic locations is a powerful way to glean new and improved knowledge from data collections and to explain the results to policymakers and the public. Particularly useful is the ability to layer different kinds of geospatial data on top of one another and see how they interact.

The next time some nasty storms are heading your way, the National Weather Service says it will have a better forecast of just how close they could come to you. The weather service started using a new high-resolution computer model that officials say will dramatically improve forecasts for storms up to 15 hours in advance. It should better pinpoint where and when tornadoes, thunderstorms and blizzards are expected.
