In the wake of recent success with air-to-air schlieren photography using the speckled desert floor as a background, researchers at NASA's Armstrong Flight Research Center, Edwards, California, are now looking to the heavens for backgrounds upon which to capture images of supersonic shock waves using ground-based cameras. A bright light source and/or speckled background – such as the sun or moon – is necessary for visualizing aerodynamic flow phenomena generated by aircraft or other objects passing between the observer's camera and the backdrop. This patent-pending method, made possible by improved image processing technology, is called Background-Oriented Schlieren using Celestial Objects, or BOSCO.
Ahead of the Asian Songbird Crisis Summit, details on the scale of Indonesia’s bird markets focus attention on the pet trade in Southeast Asia.
Introducing an open source and modular phone—these words, as we know from the anticipation engulfing Project Ara—are music to the ears of hobbyists and hackers who are always interested in taking fuller control of how their mobile companion should look and function.
(Binghamton University) Research into human fossils dating back to approximately two million years ago reveals that the hearing pattern resembles chimpanzees, but with some slight differences in the direction of humans.
The design team behind the Bloodhound Super-Sonic Car put its near-complete vehicle on show in London, ahead of an assault on the world land speed record next year.
In an off-the-cuff remark to astrophysicist Neil deGrasse Tyson, the former National Security Agency contractor suggested E.T. might send encrypted messages that humans mistake for noise

During a hearing this week, state lawmakers debated whether ride-sharing services are really tech companies, or simply high-tech cab services, with some legislators arguing fingerprint background checks would protect passengers' safety.
Dogs bark, sheep bleat and mice squeak, but what sounds do giraffes make?
Listen up, Dell and Starbucks and all the other companies that turn to consumers for new ideas about products and services. There's a better way to pry good ideas out of your customers than through the same old standard online platforms—you know, the ones that provide all users with access to other users' ideas and that group ideas into categories such as "Products" and "Experience." As a new study in the Journal of Marketing suggests, that one-size-fits-all approach may be counterproductive. According to the study, online idea-generation platforms should instead tailor themselves to the industry-specific knowledge of the customer.
Games used for exercising can improve physical and mental fitness in children with autism spectrum disorders, a new study concludes. As a way to combat a lack of physical activity, researchers investigated the use of the Makoto arena, a triangular shaped arena with pillars at each point, each with lights and sounds at various levels of the pillars. Those playing the game must hit the correct spots as they light up on different pillars.
This is not as odd a question as it sounds, and by next week I reckon a good lot of you will be pondering it. Why? Well the 30th September sees the opening of The Martian in Australia, director Ridley Scott's latest offering. It's a survivor tale, telling the plight of a lone astronaut trapped on Mars.
Physical chemistry students given most course content outside of the classroom scored 12% higher on exams than counterparts in more traditional classes where students listened to lectures, a new study by researchers at the Yale Center for Teaching and Learning and the University of Massachusetts-Amherst (U-Mass) shows.
When the Bloodhound Super-Sonic Car is unveiled this week, the public will be able to see the many innovative technologies used in its construction.
The center of our Milky Way galaxy is a mysterious place. Not only is it thousands of light-years away, it's also cloaked in so much dust that most stars within are rendered invisible. Harvard researchers are proposing a new way to clear the fog and spot stars hiding there. They suggest looking for radio waves coming from supersonic stars.
Digital downloads of songs continued to fall out of favor with Americans in the first half of the year, while free and paid music-streaming revenue kept growing, even without much of a bump from the launch of Apple Music.
New research suggests that young infants benefit from hearing words repeated by their parents. With this knowledge, parents may make conscious communication choices that could pay off in their babies' toddler years and beyond.
Kim Dotcom and three colleagues face an extradition hearing that began Monday in an Auckland courtroom. Dotcom is the colorful German-born entrepreneur who started the Internet site Megaupload, which was shut down by federal authorities in 2012. Here's what's at stake:
A spectacular rock arch in Utah is safe from collapse for now, according to a study that used a new technique to listen to the arch's natural "hum" to measure its internal health.
What do surgeons, elite-level athletes and professional musicians have in common? When they perform, the team -- be it a surgical team, a rowing team or choral ensemble -- must act harmoniously for the greatest chance of success. Athletic and musical coaching groups have developed very successful coaching strategies that improve the performance of their teams.
Researchers leverage randomness in a new computational approach to keep cells healthy. Using a newly-developed computational algorithm, they showed that this randomness within and among cells, called "noise," can be manipulated to control the networks that govern the workings of living cells -- promoting cellular health and potentially alleviating diseases such as cancer.
