All eyes on Hurricane Michael — ScienceDaily

Hurricane Michael plowed into the Florida panhandle Wednesday, Oct. 10, as a major Category 4 storm — the strongest hurricane ever to hit that region. Many NASA instruments are keeping tabs on Michael from space, including the Atmospheric Infrared Sounder (AIRS) and the Multi-angle Imaging SpectroRadiometer (MISR). The first image, taken by AIRS, shows Hurricane Michael just off the west coast of Florida on Oct. 10 in the early morning hours local time. The large purple area indicates very cold…

2018 @Scale Conference Recap – Facebook Code

The @Scale Conference is an invitation-only technical event for engineers who work on large-scale platforms and technologies. This year’s event took place on September 13 at the San Jose Convention Center, where more than 2,500 attendees gathered to discuss how to build applications and services that scale to millions or even billions of people. The conference featured technical deep dives from engineers at a multitude of scale companies, including Adobe, Amazon, Cloudera, Cockroach Labs, Facebook, Google, Microsoft, NASA, NVIDIA, Pinterest,…

From a humble plastic bag to ultra-light airplane wings — polymers are everywhere — ScienceDaily

From a humble plastic bag to ultra-light airplane wings — polymers are everywhere. These molecules are long chains of atoms that are chemically joined to play many roles that we all love (organic photovoltaics) and hate (indestructible plastic pollution). Polymers are useful in liquid form as well: the difference between tomato puree and ketchup is merely 0.5% of xanthan gum, which is a polymer made from sugar. Ketchup is thick but not sticky, all thanks to the xanthan chains that…

Curiosity rover surveys a mystery under dusty Martian skies — ScienceDaily

After snagging a new rock sample on Aug. 9, NASA’s Curiosity rover surveyed its surroundings on Mars, producing a 360-degree panorama of its current location on Vera Rubin Ridge. The panorama includes umber skies, darkened by a fading global dust storm. It also includes a rare view by the Mast Camera of the rover itself, revealing a thin layer of dust on Curiosity’s deck. In the foreground is the rover’s most recent drill target, named “Stoer” after a town in…

Uncommon Innovative Uses for a Smartphone

Smartphones have become the standard for communication in the United States and many parts of the world. Landline-based telephones have been replaced as the preferred method of vocal communication. Text messages and messenger apps are the means to which quick notes are exchanged; entire conversations spanning hours or days are held by passing messages back and forth. Access to the Internet and all of its information (real or fake) are at one’s fingertips. Posts on social media sites are made…

After 24 years of service to the MU College of Engineering, Dean Emeritus and Professor of Mechanical and Aerospace Engineering Jim Thompson retired Tuesday, celebrating his long career in engineering education with family, friends and colleagues. “I enjoyed my time here. I made more friends here than any place I have ever been, so I thank you,” Thompson…

A novel approach to provide fast, accurate translations for more languages – Facebook Code

Automatic language translation is important to Facebook as a way to allow the billions of people who use our services to connect and communicate in their preferred language. To do this well, current machine translation (MT) systems require access to a considerable volume of translated text (e.g., pairs of the same text in both English and Spanish). As a result, MT currently works well only for the small subset of languages for which a volume of translations is readily available.…

Eight aero concept innovations point the way to 75% CO2 emissions reduction by 2050

Credit: Jag_cz, Shutterstock The EU’s 2050 vision for aviation is to make Europe a world leader in sustainable aviation products and services while meeting the needs of its citizens and society. To this end, it has set an extremely challenging goal: to reduce aircraft energy consumption and CO2 emissions per passenger kilometre by 75 % by the year 2050. However, this goal wouldn’t be feasible if the aviation industry were to rely solely on the incremental improvements of state-of-the-art technologies.…

Beijing’s massive new airport ‘on time’ for 2019 launch

Beijing’s new airport will have eight runways and is expected to be used by 72 million passengers annually Amid farmlands on the outskirts of Beijing, a massive construction site rising above the horizon bustles with activity as 8,000 workers build a new mega airport. Aimed at easing passenger load from Beijing’s other two airports, Daxing International Airport is scheduled to become operational in June 2019, said Li Jianhua, vice chairman of Beijing City Planning New Airport Construction. It will…

Tough nuts, cracked in a smart way

Additive Manufacturing enables minuscule metal structures with a complex geometry to be produced. Here is a test piece compared with a match head. Using AI to monitor the manufacturing process acoustically guarantees that the workpiece is devoid of any interior defects.
