Inside the tech that makes ‘near-miss’ air collisions almost impossible

Surely then, it’s not surprising that we hear of “near-misses” between passenger jets, and of “hero pilots” avoiding “mid-air collisions”? Well yes, actually it is, because that can’t happen. These so-called “near-misses” are still a long way off from being a collision. Take the recently reported news of an Emirates Airbus A380 and an Air Seychelles Airbus A330 travelling from Mauritius to the Seychelles, for example. The two planes came closer than the safety margin required by regulations: all…

Who will control the swarm?

Who will control the swarm? Credit: iStock/Chesky_W The world is already well on its way to a day when innumerable autonomous cars and drones buzz about, shuffling commuters to work and packages to doorsteps. In fact, there is new term for it floating around the circles of engineers and venture capitalists who hope to see the day arrive sooner rather than later: They call it “The Swarm.” But this dramatic-sounding reality raises a critical question that has yet to be…

Advancing knowledge toward more efficient electronics — ScienceDaily

A recent discovery by a team of researchers led by Tulane University advances fundamental knowledge that could one day lead to more energy-efficient computers, televisions, cell phones and other electronics. The researchers’ discovery of a new magnetic topological semimetal is featured in the latest edition of the  journal Nature Materials. The Tulane team was led by physics professor Zhiqiang Mao, the Tulane School of Science and Engineering’s Outstanding Researcher for 2017. Mao’s research, which focuses on quantum materials such as…

Construction of massive neutrino experiment kicks off a mile underground — ScienceDaily

A new era in international particle physics research officially began July 21 with a unique groundbreaking held a mile underground at the Sanford Underground Research Facility in South Dakota. Dignitaries, scientists and engineers from around the world marked the start of construction of a massive international experiment that could change our understanding of the universe. The Long-Baseline Neutrino Facility (LBNF) will house the international Deep Underground Neutrino Experiment (DUNE), which will be built and operated by roughly 1,000 scientists and…

Engineering Uber Predictions in Real Time with ELK

Uber’s services rely on the accuracy of our event prediction and forecasting tools. From estimating rider demand on a given date to predicting when an UberEATS order will arrive, Uber uses forecasting algorithms to enhance user experiences (UX) across our product portfolio. To architect a precise and easily interpretable forecasting experience for engineering and operations, we built a custom prediction system by leveraging an open source distributed RESTful search engine composed of query engine Elasticsearch, data indexing pipeline Logstash, and…

Smart sensors could save lives

KAUST scientists’ disposable mobile wireless sensor nodes can be used to give early warning of industrial leaks or forest fires. Reproduced with permission from ref 1. Credit: Farooqui et al. 3-D-printed, disposable sensors capable of detecting noxious gases and changes in temperature and humidity, could revolutionize environmental monitoring. In an emergency, early warning is key to escaping from a hazard, such as a forest fire or a chemical leak. Motivated to improve on safety, a team from KAUST is using…

Pokemon’s Epic Fail in Chicago

Full disclosure:  I generally don’t play games much anymore, whether video, online, offline, board, ball, table, or hunger.  So anything I write about games is going to be at one remove as an observer, not a participant.  That isn’t necessarily bad, but in case you are an enthusiastic game player, you should know I am an outsider to all that. Nevertheless, I can imagine what it would be like to get involved in Pokemon, the online mobile phone game, to…

Technology is Disrupting the Luxury Market

The retail industry, from your nearest department store to a luxury brand shop, is undergoing massive changes in this era of digital revolution. Needless to say from changing the business models to adapting technologies like artificial intelligence, virtual reality, and even blockchain, the luxury retail market is expanding to new horizons. At this stage, customers are demanding and market conditions are extremely volatile. These conditions are important to change business strategy and adapting technology movements. There is a dire need…

Optimization for self-production may explain mysterious features of the ribosome — ScienceDaily

Optimization for self-production may explain key features of ribosomes, the protein production factories of the cell, reported researchers from Harvard Medical School in Nature on July 20. In a new study, a team led by Johan Paulsson, professor of systems biology at Harvard Medical School, mathematically demonstrated that ribosomes are precisely structured to produce additional ribosomes as quickly as possible, in order to support efficient cell growth and division. The study’s theoretical predictions accurately reflect observed large-scale features of ribosomes…

Colorimetric recognition of aldehydes and ketones — ScienceDaily

Vodka tastes different from brandy, and connoisseurs can distinguish among different brands of whiskeys. The flavors of spirits result from a complex bouquet of volatile compounds. New colorimetric sensor arrays on disposable test-strips read by hand-held devices allow for their rapid, inexpensive, and sensitive identification by their chemical “fingerprints.” They are based on novel sensor arrays that detect and differentiate among a diverse range of aldehydes and ketones, as reported in the journal Angewandte Chemie. Many volatile compounds can now…
