You're in luck. A startup called Consumer Physics has designed a hand-held spectrometer that Kickstarter supporters can get for $149. Apparently it can be used to get nutritional information (like calories, fats, proteins) for a variety of foods... including Gouda cheese.

Solar power stations in orbit aren't exactly a new idea — Asimov set one of his stories on such a space station back in 1941. Everyone thinks it's a cool idea to collect solar power 24 hours a day and beam it down to Earth. But what with the expense and difficulty of rocketing up the parts and constructing and operating the stations in orbit, nobody's built one yet. While you probably still shouldn't hold your breath, it's interesting to learn that Japan's space agency has spec'd out such a solar power station.

Currently, the best way to check if a person has a high likelihood of developing Alzheimer's is to perform a PET scan to measure the amount of amyloid plaque in his or her brain. That's an expensive procedure. But a startup called Akili Interactive says it has developed a mobile game that can identify likely Alzheimer's patients just by their gameplay and game results. The game is based on a neuroscience study which showed that multitasking is one of the first brain functions to take a hit in Alzheimer's patients. Therefore the game requires players to perform two tasks at the same time.

The AI known as IBM Watson has been a Jeopardy champion, is training to become a doctor, and will soon add geneticist to its list of titles. Yesterday IBM and the NY Genome Center announced a collaboration in which oncologists will give Watson reams of genetic data for 20 brain cancer patients. The AI will search through vast troves of medical literature for information regarding each patient's specific set of genetic mutations, then offer treatment suggestions.

The condom-making company Durex is imagining a brave new world of lovemaking. At SXSW, the company's prototype Fundawear was unveiled. These undergarments feature tiny vibrators that can be activated remotely when the wearer's partner taps or strokes a smartphone screen.

Before you give the obvious answer (no), take a moment to consider. The Van Allen radiation belts, zones of high-energy charged particles that ring the Earth, can cause all manner of trouble to satellites and spacecraft that pass through them. And shielding is so boring. So scientists are experimenting with hacking the belts; more specifically, they think they can use carefully tuned electromagnetic waves to drive these particles out of space and disperse them in the Earth’s upper atmosphere. Say it with me now: What could possibly go wrong?

In Japan, workers have spent nearly three years on the clean-up and decommissioning of the ruined Fukushima Daiichi nuclear power station. They only have 37 years to go.
Taking apart the plant's three melted-down reactors is expected to take 40 years and cost $15 billion. The plant's owner, TEPCO, admits that its engineers don't yet know how they'll pull off this monumental task. An in-depth examination of the decommissioning process explains the challenges, such as working amid the radioactive rubble, stopping up the leaks that spill radioactive water throughout the site, and handling the blobs of melted nuclear fuel. Many of the tasks will be accomplished by newly invented robots that can go where humans fear to tread.

The former editor of Wired is betting that the 21st century skies will be filled with drones, and not the military sort. His company, 3D Robotics, is building open-source UAVs for the civilian market, and expects its drones to catch on first in agriculture. As noted in an article about the company's grand ambitions: "Farms are far from the city’s madding crowds and so offer safe flying areas; also, the trend toward precision agriculture demands aerial monitoring of crops. Like traffic watching, it’s a job tailor-made for a robot: dull, dirty, and dangerous." Also, farmers apparently wouldn't need FAA approval for privately owned drones flying over their own property.

Chinese engineers love their superlatives: Biggest dam, fastest train, etc etc. Now they've constructed the deepest underground dark matter detector beneath a mountain in Sichuan province. Such dark matter seekers have to be buried deep to shield them from cosmic rays, because that radiation would be picked up by the detector and could be confused for radiation generated by dark matter. Other dark matter detectors are similarly subterranean: LUX, in the United States, is at the bottom of an abandoned mine in South Dakota, and a European effort called XENON lies below the Gran Sasso mountain. The Chinese researchers hope their PandaX detector will finally reveal the much-hypothesized, never-seen dark matter particles known as WIMPs.

When surgeons set out to repair holes in the walls of the heart's chambers or in blood vessels, they often do invasive open-heart surgery and use sutures, staples, and glue to keep a patch in place. But the sutures and staples are a rough fix, and many of the glues on the market today don't work well on wet tissue that's continually flexed by the heart's contractions and the movement of pumping blood. Today biomaterial researchers announced a new light-activated glue that could make surgery less invasive, quicker, and easier. The adhesive was inspired by slugs' and sandcastle worms' sticky secretions, which work underwater, and it can be applied with slender tools during minimally invasive surgery. A flash of UV light then sets the glue, which bends and flexes with the tissue.

"As 2014 dawns, China has the most active and ambitious space program in the world," says this article. While it's true that the Chinese space agency is just now reaching milestones that the U.S. and Russia reached 40 years ago (its first lunar rover landed in December), the Chinese government's strong support for space exploration means that it's catching up fast. On the agenda for the next decade: A space station to rival the ISS, a new spaceport, new heavy-lift rockets, a global satellite navigation system to rival GPS, and China's first space science satellites.

If you can't fix it, go around it. That's the thinking behind an experimental treatment for traumatic brain injury. Using an implanted microdevice, researchers recorded the electrical signals from a sensory region of a rat's brain, skipped over a damaged brain region that typically processes sensory information, and sent the electric signals on to the premotor cortex. This cyborg mouse could then move normally. What this means is that we're getting better at speaking the brain's language — even if we don't understand it, we can mimic it. W/ dramatic video.

Paleoscatologist Karen Chin knows you can learn a lot about ancient ecosystems by studying coprolites — fossilized feces. She has studied dino droppings from herbivores, and identified the types of plants those dinosaurs ate. She has identifed T. rex turds, and found evidence that prehistoric dung beetles made use of those king-sized dino patties. This profile of Chin goes through her greatest hits, then focuses on her latest work, which sheds light on the reemergence of life after the K-Pg extinction event that brought down the dinosaurs... but left some surprising creatures unscathed.

In spinal cord injuries, the brain's commands can't reach the lower body — so in a ground-breaking experiment at the University of Louisville, researchers are providing artificial commands via electrodes implanted in the spine. The first paralyzed people to try out the tech have already been able to stand on their own, and have regained some bowel and sexual function. A video that accompanies the article also shows paralyzed rats that were able to walk again with this kind of electrical stimulation.

About four million people around the world have pacemakers implanted in their bodies, and those devices all got there the same way: surgeons sliced open their patients' shoulders and inserted the pulse-generating devices in the flesh near the heart, then attached tiny wires to the heart muscle. This invasive surgery carries risks of infection, of course, and those delicate wires are often the failure point when pacemakers stop working.
A device that just received approval in the EU seems to solve those problems. This tiny pacemaker is the first that doesn't require wires to bring the electrical signal to the heart muscle, because it's implanted inside the heart itself, and is hooked onto the inner wall of one of the heart's chambers. This is possible because the cylindrical device can be inserted and attached using a steerable catheter that's snaked up through the femoral artery. This blog post has an animation of the insertion process.
