JoshuaInNippon writes "Might we one day be able to use our cell phone cameras to pick out the best piece of meat on display at the market? Some Japanese researchers seem to hope so. A team of scientists is using infrared camera technology to try and determine the tastiest slices of high-grade Japanese beef. The researchers believe that the levels of Oleic acid found within the beef strongly affect the beef's tenderness, smell, and overall taste. The infrared camera can be tuned to pick out the Oleic acid levels through a whole slab, a process that would be impossible to do with the human eye. While the accuracy is still relatively low — a taste test this month resulted in only 60% of participants preferring beef that was believed to have had a higher level of Oleic acid — the researchers hope to fine tune the process for market testing by next year."

Scientists have found ten new emperor penguin colonies by spotting their skid marks on the Antarctic ice from satellite images (video on page). The ice around the penguins gets very dirty because they congregate in a small area in very large colonies for months. Peter Fretwell, Mapping Expert, British Antarctic Survey says, "What we find is that we can see the guano (excrement) from space. They stay in the same space in very large colonies for eight months of the year and the ice around them gets very dirty, and it's that that we can see on the satellite images."

Hugh Pickens writes "Researchers have developed a camera that snaps images less than a half a billionth of a second long and can capture over six million images in a second continuously. Dubbed Serial Time-Encoded Amplified imaging, or Steam, the technique depends on carefully manipulating so-called 'supercontinuum' laser pulses. While other cameras used in scientific research can capture shorter-lived images, they can only capture about eight images, and have to be triggered to do so for a given event. The Steam camera, by contrast, can capture images continuously, making it ideal for random events that cannot be triggered. Keisuke Gode, lead author of the study, and his colleagues used their camera to image minute spheres flowing along a thin tube of water in a microfluidic device." (More below.)

jandersen writes "While I generally don't play computer games, I do occasionally play games like Crossfire or The Mana World, because they have more of a story line and allow you to go at your own pace. What I don't care much about, though, is that they are still focused on killing monsters and amassing wealth, and it gets very tedious after a while. Are there really no games where the goal isn't so much about increasing your own power and defeating others, but where you instead grow by doing things that benefit others, where enemies shouldn't be killed out of hand, but befriended; where learning, teaching, research and social skills are more important than killing and conquering? Would people be interested in a game of that nature?"

MoonUnit writes "Technology Review has an interesting article about the way CAPTCHAS are fueling AI research. Following recent news about various textual CAPTCHAs being cracked, the article notes that a researcher at Palo Alto Research Center has now found a way crack photo-based CAPTCHAs too. Most approaches are based on statistical learning, however, so Luis von Ahn (one of the inventors of the CAPTCHA) says it is usually possible to make a CAPTCHA more difficult to break by making a few simple changes."
