Foul-smelling, toxic mosquito repellent could soon become a thing of the past  (Photo: Shu...

Methods for controlling mosquitoes usually take two tacks: luring the mosquitoes into a trap away from humans, or discouraging them from biting at the source. Both methods can be expensive, unhealthy, cumbersome, or disgusting (the smell of rancid butter, anyone?) and generally aren’t scalable for the countries that suffer the most from mosquito-borne disease. New research explores how a mosquito’s neurons actually detect humans, and presents a promising class of chemicals, screened for safety, cost, and an appealing scent, some of which attract mosquitoes and others of which mask the smell of tasty human skin.  Read More

P/2013 P5 is an asteroid with six comet-like tails (Image: NASA, ESA, and D. Jewitt)

In the old days, astronomy was simple – comets had tails and asteroids didn’t. Now, as if to not only disprove such established views, but drive the point home, NASA's Hubble Space Telescope took images in September of an asteroid called P/2013 P5 that has not one, but six comet-like tails.  Read More

The Tri-D engine test firing

Like something out of a Robert Heinlein novel, students at the University of California, San Diego (UCSD) have built a metal rocket engine using a technique previously confined to NASA. Earlier this month, the students conducted a hot fire test for a 3D-printed metal rocket engine at a launch site in California’s Mojave Desert. This is the first such test of a printed liquid-fueled, metal rocket engine by any university in the world and the first designed and printed outside of NASA.  Read More

Innovation is all about putting on the proverbial thinking cap. Now engineers are vying to produce an actual thinking cap – at least one that can measure the most rudimentary signals of thought. The US Department of Defense is pushing for the development of cheap, wearable systems that can detect the brain waves of people and display the data on smartphones or tablets.  Read More

Researchers have discovered which receptors mosquitoes use to detect DEET (Photo: Shutters...

Nothing keeps the mosquitoes away quite as well as DEET, but it's not the most innocuous of substances – besides stinking, it also melts plastic and synthetic fabrics, plus it's even been linked to problems in users' central nervous systems. It can also be prohibitively expensive for use in developing nations. Thanks to research being conducted at the University of California, Riverside, however, a new generation of non-toxic but highly-effective repellants may be on its way.  Read More

Computer scientists have come up with a new simple, accurate way to simulate the appearance of fabric that could change the way artists and animators in the film and computer game industries go about the business of rendering computer-generated clothing and other materials.  Read More

The Kite Mosquito Patch is worn on the clothing like a decal, and is said to keep mosquito...

Depending on what part of the world you live in, mosquitoes can range from being an annoyance, to acting as carriers of life-threatening diseases such as malaria and West Nile virus. Sprays containing deet do a fairly decent job of keeping the mozzies at bay, but they’re also highly toxic. Less-nasty sprays, bracelets and other devices are also available, although (as I can attest to from personal experience) they tend not to be very effective. Now, however, a group of California-based entrepreneurs are developing what could be the ultimate deterrent – the Kite Mosquito Patch.  Read More

Like her mittens, the 3D glasses might one day be optional (Photo: Miki Yoshihito)

Researchers at the University of California Santa Cruz have developed a 3D display which can also be viewed in 2D without glasses, and without the blurred effect caused by overlapping images. Though, as you'd expect, the screen displays both left and right images, it also emits a mysterious third image which is the key to the technology.  Read More

The Yamaha RMax helicopter used in the UC Davis tests

Researchers at University of California are testing UAV crop dusting on the Oakville Experimental Vineyard at the UC Oakville Station using a Yamaha RMax remote-controlled helicopter. The purpose is to study the adaptation of Japanese UAV crop dusting techniques for US agriculture, but not all the hurdles they face are technological.  Read More

“Quick, send in the robots!” Far-fetched as it may sound, fire-fighting robots are indeed coming closer and closer to common use. While some of them are intended to actually put out the flames, others are designed more to scout out structures before human firefighters enter, letting those people know how to safely get around and where to concentrate their efforts. One of the latest machines in the second category is the self-balancing Firefighting Robot (FFR), being developed at the University of California, San Diego.  Read More
