Three Ground-Breaking Miniature Biosensors 18

kkleiner writes "Over the past few years, several research teams have developed increasingly smaller and cheaper biosensors with improved detection capabilities and faster turnaround times. Whether you are a doctor diagnosing patients in the rural areas of Africa or a Homeland Security agent working to thwart an act of bioterrorism, one of these little devices should be your sidekick."

Empathy Is For the Birds 201

grrlscientist writes "Common Ravens have been shown to express empathy towards a 'friend' or relative when they are distressed after an aggressive conflict — just like humans and chimpanzees do. But birds are very distant evolutionary relatives of Great Apes, so what does this similarity imply about the evolution of behavior?"

Doubled Yield For Bio-Fuel From Waste 97

hankwang writes "Dutch chemical company DSM announced a new process for production of ethanol from agricultural waste. Most bio-fuel ethanol now is produced from food crops such as corn and sugar cane. Ethanol produced from cellulose would use waste products such as wood chips, citrus peel, and straw. The new process is claimed to increase the yield by a factor of two compared to existing processes, thanks to new enzymes and special yeast strains."

Chinese Companies Rent White Foreigners 145

The job market may look bad here, but if you're in China, and you happen to be white, all you need is a suit and tie. An increasing number of Chinese companies are willing to pay any price to have a few fair-skinned faux employees walking around. From the article: "'Face, we say in China, is more important than life itself,' said Zhang Haihua, author of Think Like Chinese. 'Because Western countries are so developed, people think they are more well off, so people think that if a company can hire foreigners, it must have a lot of money and have very important connections overseas. So when they really want to impress someone, they may roll out a foreigner.' Or rent one."

36-Hour Lemmings Port Gets Sony Cease and Desist 268

Zerocool3001 writes "The recently featured 36-hour port of the original Palm version of Lemmings to the iPhone and Palm Pre has received a cease and desist letter from Sony. Only one day after submitting the app for approval on the two app stores, the developer has put up a post stating that he 'did this as a tribute to the game — we can only hope that Sony actually does a conversion for platforms like iPhone and Palm Pre in the near future.' The text of the cease and desist letter is available from the developer's website."

FEMA and DHS Fund Disaster Hero Game 68

eldavojohn writes "The United States government has decided that children need a video game to learn about what to do before, during, and after an emergency or hazardous event. Collect an emergency kit! Create an emergency plan! Be informed of what to do! Suffer from heat exhaustion inside the Superdome! ... Wait, what? Oh, I guess FEMA omitted that last one. Disaster Hero is coming in 2011 — plenty of time before 2012."

Snails On Methamphetamine 93

sciencehabit writes "Science answers the question: What happens when you put a snail on speed? From the article: 'The results suggest that meth improves memory, something that has been previously observed in creatures with large, complex brains like rats and humans. But since the snails store their memories in a simple, three-neuron network, the team hopes that studying the meth effect in these gastropods will help pinpoint how the drug's memory magnification powers work.'"

When Rewriting an App Actually Makes Sense 289

vlangber writes "Joel Spolsky wrote a famous blog post back in 2000 called 'Things You Should Never Do, Part I,' where he wrote the following: '[T]he single worst strategic mistake that any software company can make: They decided to rewrite the code from scratch.' Here is a story about a software company that decided to rewrite their application from scratch, and their experiences from that process."

PETA Creates New Animal-Friendly Software License 356

Anders writes "People for the Ethical Treatment of Animals, the largest animal rights organization in the world, endorse a new FLOSS license. From the article: 'The Harm-Less Permissive License (HPL) is a permissive, non copyleft, software license. It is based on the FreeBSD license but with one additional restriction; the "harm-less" clause. It prevents software, licensed under the HPL, to be used for harming humans or animals.'" I guess this leaves the bunny-fueled power plant in Stockholm out in the cold.

Girl Claims Price Scanner Gave Her Tourette's Syndrome 558

Attorneys for Dominica Juliano claim that she was burned and developed psychological problems after a store clerk aimed a hand-held price scanner at her face. Store attorneys say their scanners uses a harmless LED light and that the girl had serious health problems before she was scanned. From the article: "Dominica Juliano was 12 when she and her grandmother entered the Country Fair store in Erie in June 2004. A clerk allegedly called the girl 'grumpy' before flashing his hand-held bar code scanner over her face and telling her to smile. Attorneys for Ms. Juliano and her guardian say the girl was sensitive to light and burned, and later developed post-traumatic stress and Tourette's syndrome."

Comment Re:As someone who was better than average... (Score 1) 427

This is the book I pull out every time I need to teach or tutor something in math below about linear algebra, calculus, or about half of college algebra:
Mathematics From the Birth of Numbers
It has a few mistakes due to lack of imagination, for example the proposed number system for the caveman is more capable than the author imagines. Anyway it's a fabulous teaching tool and a fairly fun read besides.

Addicting Mice To Light 92

Al writes "In an attempt to better understand how the reward system in the brain functions in people suffering from addiction, scientists at Stanford have created mice that are addicted to light. They engineered light-sensitive proteins to trigger signaling pathways in the nucleus accumbens, a part of the brain that responds to pleasurable stimuli. They then connected a fiber-optic cable to this part of the brain and delivered a blast of light whenever the mice wandered into a 'reward chamber.' In previous experiments the mice have been given drugs like cocaine or amphetamine when they enter these rooms. The light treatment works in exactly the same way but lets the researchers very precisely control timing and dose of reward administered to the brain. The approach could also provide a way to probe receptors that cannot be accessed using existing drugs."

Comment Re:Advertising (Score 1) 234

It took me forever to find a copy of Beyond Good and Evil. It was a great idea for a game, but unfortunately it wasn't actually playable. A couple hours in I reached a point with infinite enemy spawns and a way forward that had to be opened by the AI partner. Even if I killed all the present enemies and told the AI partner to open the way forward he would, instead, attack the next enemy to spawn.

Robot Love Goes Bad 101

hundredrabh writes "Ever had a super needy girlfriend that demanded all your love and attention and would freak whenever you would leave her alone? Irritating, right? Now imagine the same situation, only with an asexual third-generation humanoid robot with 100kg arms. Such was the torture subjected upon Japanese researchers recently when their most advanced robot, capable of simulating human emotions, ditched its puppy love programming and switched over into stalker mode. Eventually the researchers had to decommission the robot, with a hope of bringing it back to life again."

New Google Favicon Deja Vu All Over Again? 227

theodp writes "Last June, Google rolled out a new favicon, the small branding icon that graces your URL bar when you visit Google. Which, as it turned out, bore a striking similarity to Garth Brooks' Circle-G logo. Well, Google went back to the drawing board and has come back with a new favicon, which it says was inspired by — not copied from, mind you — its users' submitted ideas. Some are also seeing inspiration elsewhere for the new favicon, which consists of white 'g' on a background of four color swatches. Take the AVG antivirus icon, for instance. Or everybody's favorite memory toy, Simon. Or — in perhaps the unkindest cut of all — the four-color Microsoft Windows logo, shown here with a superimposed white '7'. Anything else come to mind?" What comes to mind for me is just how obsessed many people are with the Google favicon.
