NASA-Supported Techniques are "Best Practice" for UN Disaster Risk Reduction Guidelines

More than 925,000 Rohingya refugees currently reside in Bangladesh, but the camps they stay in are at risk from deadly landslides, especially during monsoon season. Decision makers there are using NASA Earth observations to inform which areas are most at risk – and now, the United Nations Office for Disaster Risk Reduction (UNDRR) has incorporated these practices into a set of...

March Madness bracket analysis shows picking final four first leads to better brackets

Data science researchers at the University of Illinois have some March Madness advice based on new research: Pick top-seeded teams as the Final Four in your March Madness bracket and work backward and forward from there. If you are going to submit multiple brackets—as you can in the ESPN, CBS Sports and Yahoo Challenges—starting with the Final Four is still a good strategy, but make sure you...

Study find delta helps to decrease the impact of river flooding

Most coastal cities and ports face a double threat from storm surge and river flooding. Infrastructure development along waterways and sea-level rise increase vulnerability for these communities. In a recent publication, The Propagation of Fluvial Flood Waves Through a Backwater-Estuarine Environment, historical data is examined to determine how to reduce the risk of coastal river flooding to...

'Category Hell:' 6 months after Dorian, where do things stand?

Six months ago, Hurricane Dorian, one of the most destructive storms in recorded history and the worst storm in the history of the Bahamas, turned lives upside down.The Category 5 behemoth wasn't just devastating because of its size, but also its slow-moving nature. The storm sat for nearly two full days over the northern part of the archipelago, moving at a glacial speed of 1.3 mph. All the...

Climate Change Affected Australia's Wildfires, Scientists Confirm

Confirming what had been widely suspected, researchers have found that human-caused climate change had an impact on Australia's recent devastating wildfires, making the extremely high-risk conditions that led to widespread burning at least 30% more likely than in a world without global warming.The researchers said the full influence of climate change on the fires was probably much greater, but...

Scientists demonstrate first non-volatile nano relay operation at 200°C

Researchers have come up with a new type of nanoelectromechanical relay to enable reliable high-temperature, non-volatile memory. The work is an important development for all-electric vehicles and more-electric aircraft which require electronics with integrated data storage that can operate in extreme temperatures with high energy efficiency.
