XSEDE Stampede2, ECSS helps simulate shock turbulence interactions — ScienceDaily

This may come as a shock, if you’re moving fast enough. The shock being shock waves. A balloon’s ‘pop’ is shock waves generated by exploded bits of the balloon moving faster than the speed of sound. Supersonic planes generate a much louder sonic ‘boom,’ also from shock waves. Farther out into the cosmos, a collapsing star generates shock waves from particles racing near the speed of light as the star goes supernova. Scientists are using supercomputers to get a better…

Over a century of Arctic sea ice volume reconstructed with help from historic ships’ logs — ScienceDaily

Our knowledge of sea ice in the Arctic Ocean comes mostly through satellites, which since 1979 have imaged the dwindling extent of sea ice from above. The University of Washington’s Pan-Arctic Ice Ocean and Modeling System, or PIOMAS, is a leading tool for gauging the thickness of that ice. Until now that system has gone back only as far as 1979. A new paper now extends the estimate of Arctic sea ice volume back more than a century, to 1901.…

The Moon, Mars, or Stay Home?

This coming Saturday marks the fiftieth anniversary of the first landing of humans on the moon.  I remember staying up late in my bathrobe and watching the blurry images on our old black-and-white tube-model TV as Neil Armstrong first set foot on the dusty surface.  I was no more moonstruck than most fifteen-year-olds were at the time.  I enjoyed the attention that engineers and high technology were getting as a part of the space program.  But the geopolitical forces that…

unique test bench to measure collision impact

No drones allowed in the vicinity of helicopters. Credit: Michael May The rapid rise in the number of drones worldwide has been accompanied by increasing reports of near misses with commercial aircraft. In 2017, while coming in to land, a Canadian passenger aircraft actually collided with a drone, narrowly escaping catastrophe. Bird-strike tests for aircraft are mandatory. To date, however, there is no equivalent standard test procedure for collisions with drones. In order to to be able to fundamentally understand…

Solving for Urban Air Travel: A Q&A with François Sillion, Director of Uber ATCP

Bolstering Uber’s position at the leading edge of transportation technology, the new Advanced Technologies Center in Paris (ATCP) supports the development of Uber Air, our effort to add a third dimension to our platform using flying vehicles.  Leading ATCP is François Sillion, who recently served as director of artificial intelligence at Inria, France’s national research institute for the digital sciences. François earned his Ph.D. in Physics and Computer Graphics from the Ecole Normale Supérieure and has enjoyed a long career…

Interior wall brings breath of fresh air to home of the future

Bill Hutzel, a professor of mechanical engineering technology, and Danielle LeClerc, an undergraduate student who works on the Biowall team, are inspecting the plants used for the project. Credit: Purdue Research Foundation image/Hope Sale More than 3.8 million deaths worldwide each year are blamed on household air pollution, and scientists are turning to many strategies to try to clean the air in homes and business, including the use of everyday plants. A Purdue University project called the Biowall is showing…

No direct link between North Atlantic currents, sea level along New England coast — ScienceDaily

A new study by the Woods Hole Oceanographic Institution (WHOI) clarifies what influence major currents in the North Atlantic have on sea level along the northeastern United States. The study, published June 13 in the journal Geophysical Research Letters, examined both the strength of the Atlantic Meridional Overturning Circulation (AMOC) — a conveyor belt of currents that move warmer waters north and cooler waters south in the Atlantic — and historical records of sea level in coastal New England. “Scientists…

How do foams collapse? Two distinct physical mechanisms identified for how simple foams collapse — ScienceDaily

Researchers from Tokyo Metropolitan University have successfully found two distinct mechanisms by which foams can collapse, yielding insight into the prevention/acceleration of foam rupture in industrial materials e.g. foods, cosmetics, insulation, stored chemicals. When a bubble breaks, they found that a collapse event propagates via impact with the receding film and tiny scattered droplets breaking other bubbles. Identifying which mechanism is dominant in different foams may help tailor them to specific applications. Foams play a key role in a wide…

Boeing wanted to wait 3 years to fix Max flaw

Credit: CC0 Public Domain Two key lawmakers said Friday that Boeing planned to delay fixing a nonworking safety alert on its 737 Max aircraft for three years and sped up the process only after the first of two deadly crashes involving Max planes last October. U.S. Reps. Peter DeFazio of Oregon and Rick Larsen of Washington disclosed the decision in letters sent to Boeing and the Federal Aviation Administration seeking details on what the plane maker and the agency knew…
