No matter the colour or texture of their surroundings, squid are masters of camouflage, blending in to the scenery to avoid detection. Now, researchers from the University of California Irvine have isolated the source of the creature's disappearing act: a protein appropriately named reflection. Additionally, when the researchers layered this protein on a piece of tape, it rendered the tape invisible in particular wavelengths of light. The researchers presented their work this week at the meeting of the American Chemical Society in Denver.
Applied Aeronautics sees its new Albatross drone as one perched between two extremes in unmanned aircraft: the low cost and high breakability of traditional hobbyist drones on one end, and the high cost of durable, professional drones on the other. With a crowdfunding project well under way, Applied Aeronautics hopes that its drone can swoop into the sweet spot in the middle, creating a useful tool that people can actually buy and use.
This morning, Governor Mike Pence of Indiana declared a state of emergency in Scott County, in the southeast of the state, due to what is being called the worst HIV outbreak in the state's history. The cases were all caused by intravenous drug use, but some health officials fear that a rapid, short-term response will not be enough in the face of a large drug abuse problem.
French drone hobbyist Olivier C is building a drone navy. It started with a Millenium Falcon drone, then followed by a TIE Interceptor drone. Now, Olivier C has moved beyond smugglers and starfighters to deliver a capital ship: an Imperial Star Destroyer. Like his previous Star Wars drones, the Star Destroyer is a foam body built on top of a custom quadcopter chassis, and there are giant circular holes in the Star Destroyer's shape to accommodate the quadcopter's spinning rotors.
Spending long summer evenings outside comes with a big nuisance: bug bites. Mosquitos and other insects are drawn to the lights illuminating your dinner party, which helps them hone in on their human prey. While that might mean a few days of itchy welts for some of us, the implications are much more dire in other countries where bug bites can mean infection of some nasty diseases such as leishmaniasis, Chagas disease, and malaria. Now, a team of researchers is experimenting with LED lights that can ward off insects but still appear as functional white light for humans. They published their findings in the May issue of the journal Philosophical Transactions B.
With a click of the trigger, the gbg-8 shoots! Except it's not expelling bullets; it's taking a picture. In essence, the gbg-8 is a camera masquerading as a gun. After taking a photo, with a camera mounted inside the "barrel," the image become visible on the cannibalized screen of a gameboy mounted on the side of this weird piece of cyberpunk gadgetry. In seconds, a thermal printer then spits out the image on paper. Made by the artist vtol in Moscow, it seems less about the functionality--there are better cameras and portable printers out there--and more about the materials used. Built from a game boy, an arduino board, a camera of unknown origin, and a thermal printer, gbg-8 is an alternate vision of the 1990s where polaroids were outlawed and only outlaws made polaroids.
A little over two weeks from now, the Apple Watch will be on display at Apple Stores around the world, and much of the mystery over the product will have evaporated. But for now, if you're looking to see what Apple's smartwatch looks like on your own wrist, your only recourse is to turn to technology.
Rice, the base for cuisines all over the world, contains a lot of starch. That makes it delicious but also high in calories. While that may a boon for people who struggle to ingest enough calories each day, it's becoming a problem for people with sedentary lifestyles who are eating too many calories. The result is a worldwide obesity crisis, and, surprisingly, the percent of obese adults is increasing faster in developing countries. Now a team of Sri Lankan researchers has devised a new way to cook rice that reduces the amount of starch--and calories--the body absorbs from rice by up to 60 percent. The researchers presented their findings this week at the meeting of the American Chemical Society in Denver.
NASA is working on a prototype drone that will be able to survey Mars from a modest altitude. But what if instead of shipping a drone to Mars, we could just ship small vials of cells, and use them to grow a biodegradable drone on the Red Planet? A team of students from Stanford University, Spelman College, and Brown University created such a drone last summer, which they then entered into the 2014 International Genetically Engineered Machine competition.
