LEDs are the future of lighting but they aren't new.  British experimenter H. J. Round reported a light-emitting solid-state diode in 1907 while Oleg Vladimirovich Losev published the paper "Luminous carborundum [[silicon carbide]] detector and detection with crystals" in Telegrafiya i Telefoniya bez Provodov (Wireless Telegraphy and Telephony) but they were truly basic research and  no real work was done with them for decades.

In 1962, Nick Holonyak, Jr. of the General Electric company patented the first practical LED and by the late 1960s they were in common use.

Almost all scientists claim citizen science is a good thing.  Hey, doctors all claim that patients who can Google and ask a lot of questions about diseases and treatements are a good thing also.  But not all really feel that way.

Climate scientists certainly wish there was less citizen science. If they wanted to shut up climate deniers (and skeptics) about data, they would do what physicists do - send all 10 billion pieces of raw data. Good luck making sense of that, citizen scientists.  Biologists could also likely do with fewer people who know just enough science to be wrong.

On June 23rd, the 100th anniversary of the birth of Alan Turing, a contest at Bletchley Park, where Turing was key in cracking the Nazi Enigma code during World War II, saw Eugene Goostman win the biggest Turing test ever staged.

Except Eugene is not a person, it is a chatbot with the 'personality' of a 13-year-old boy in the Ukraine.

The Turing test is what Turing considered a threshold for believability, an evaluation of machine intelligence; a machine that fooled humans into thinking it was human 30 per cent of the time will have beaten the test. 

What, a herd of cattle were poisoned by cyanide in Texas??  The culprit had to be a genetically-modified form of Bermuda grass!  Stupid scientists are out to kill us all with their right-wing, corporation-y greed.

Only if you get your science from CBS.  Or Sierra Club.  Or gullible commenters here on Science 2.0.

Fundamentalist extremists don't like anything that looks like it didn't come from their religious texts. And they tend to blow stuff up that they don't like.

Five years ago, the Taliban blew the face off a towering, 1,500-year-old rock carving of Buddha, called Jahanabad Buddha, which was etched high on a huge rock face in the 6th or 7th century in northwest Pakistan.  Hard-line Muslims have a history of targeting Buddhist, Hindu and other religious sites they consider heretical to Islam. Six months before the Sept. 11, 2001 terrorist attacks, the Taliban outraged the world by dynamiting a pair of 1,500-year-old Buddhist statues in central Afghanistan.  

For science credibility about biology, who means more?

Traditional Chinese medicine (TCM) is enjoying increasing popularity all over the world - to the tune of hundreds of millions of dollars each year, making it Big Business.

Yet there are concerns. Two molecular genetics studies show that the treatments can be harmful, as well, because not all of their ingredients are listed, or even legal, some can cause cancer and proponents often simply do not know what they are doing when making combinations. 

The Utopian vision society has always dreamed about was a world where people could eat so much for so little money, that it wasn't just rich people who could afford to be fat; anyone could.

Well, we have that. America is more self-loathing about its obesity issues than most countries but Italian kids are fat, everyone in Britain is fat, and even the French are closing in on a weight crisis.

A few days away from a Supreme Court ruling on the the Patient Protection and Affordable Care Act(Obamacare to detractors) comes some sobering claims from Britain, which already has nationalized health care.

Professor Patrick Pullicino, a consulting neurologist for East Kent Hospitals and Professor of Clinical Neurosciences at the University of Kent, says National Health Service (NHS) doctors in the UK are prematurely ending the lives of thousands of elderly hospital patients because they are difficult to manage or to free up beds.
