You're thinking of the low-power versions. If you look at something higher-powered, such as a Cree XR-E, then yes - you will need decent heatsinking to prevent the LED from frying itself.

Your assumption is like talking about a P4 CPU, and assuming it has the same thermal requirements as a low-end ARM CPU. Without heatsinking, the P4 will melt in short order - but the ARM will be just fine.

The Mass Production of Living Tissue 157

Posted by Soulskill from the syfy-has-already-bought-movie-rights dept.
An anonymous reader sends in this moderately disturbing quote from Gizmodo: "I'm touching a wet slab of protein, what feels like a paper-thin slice of bologna. It's supple, slimy, but unlike meat, if you were to slice it down the center today, tomorrow the wound would heal. It's factory-grown living tissue. The company behind the living, petri-dish-grown substance known as Apligraf hates my new name for it: meat band-aid. 'It's living,' Dr. Damien Bates, Chief Medical Officer at Organogenesis, corrects me. 'Meat isn't living.' But no one argues with me that this substance is really just a band-aid. A living, $1500 band-aid, I should say. Apligraf is a matrix of cow collagen, human fibroblasts and keratinocyte stem cells (from discarded circumcisions), that, when applied to chronic wounds (particularly nasty problems like diabetic sores), can seed healing and regeneration. But Organogenesis is not interested in creating boutique organs for proof of concept scientific advancement. They're a business in the business of mass tissue manufacturing — and the first of its kind."
It's funny. Laugh.

Vatican Debates Possibility of Alien Life 721

Posted by Soulskill from the vulcan-jesus-raises-an-eyebrow dept.
Pickens writes "The Telegraph reports that the Vatican's Pontifical Academy of Sciences is holding its first ever conference on alien life, the discovery of which would have profound implications for the Catholic Church. For centuries, theologians have argued over what the existence of life elsewhere in the universe would mean for the Church. Among other things, extremely alien-looking aliens would be hard to fit with the idea that God 'made man in his own image' and Jesus Christ's role as savior would be confused; would other worlds have their own Christ-figures, or would Earth's Christ be universal? Just as the Church eventually made accommodations after Copernicus and Galileo showed that the Earth was not the center of the universe, and when it belatedly accepted the truth of Darwin's theory of evolution, Catholic leaders say that alien life can be aligned with the Bible's teachings. 'Just as a multiplicity of creatures exists on Earth, so there could be other beings, also intelligent, created by God,' says Father Jose Funes, a Jesuit astronomer at the Vatican Observatory and one of the organizers of the conference. Others do not agree. 'If you look back at the history of Christian debate on this, it divides into two camps. There are those that believe that it is human destiny to bring salvation to the aliens, and those who believe in multiple incarnations,' says Paul Davies, a theoretical physicist. 'The multiple incarnations is a heresy in Catholicism.'"

Con Kolivas Returns, With a Desktop-Oriented Linux Scheduler 333

Posted by timothy from the dare-not-speak-its-name dept.
myvirtualid writes "Con Kolivas has done what he swore never to do: returned to the Linux kernel and written a new — and, according to him — waaay better scheduler for the desktop environment. In fact, BFS appears to outperform existing schedulers right up until one hits a 16-CPU machine, at which point he guesses performance would degrade somewhat. According to Kolivas, BFS 'was designed to be forward looking only, make the most of lower spec machines, and not scale to massive hardware. i.e. [sic] it is a desktop orientated scheduler, with extremely low latencies for excellent interactivity by design rather than 'calculated,' with rigid fairness, nice priority distribution and extreme scalability within normal load levels.'"
