This article is about a new kind of simple computational rule ("LACE rules" running on LACE, the Link Automata Computing Engine platform) which, when applied locally on a grid of cells, demonstrates fascinating emergent "artificial life" behavior.
Jump to follow-up “Statistical regression to the mean predicts that patients selected for abnormalcy will, on the average, tend to improve. We argue that most improvements attributed to the p…
A new underwater communication and networking technique can achieve kilometer-scale ranges while consuming about one-millionth the power required by current communication methods.
Wonderful news! We just received full funding for the Galileo Project expedition to scoop the fragments of the first interstellar meteor…
You, dead, are so much better than anyone else alive. – Richard Feynman, to his wife, Arlene Richard Feynman is famous for his ceaseless questioning of life and the universe, to a degree unexpected even for being a Nobel Prize quantum physicist. His dogged investigation of the Challenger explosion is the most…
Liquid metal printing, developed by MIT researchers, rapidly creates 3D metal structures by depositing molten aluminum along into a bed filled with microscopic glass beads. The process can produce low-resolution objects like frames for chairs and tables in minutes.
Contribution by Philip Ham: attractor.basic and Python implementation by Johan Bichel Lindegaard.
Some intuition about this topic can be developed without summoning the ghost of Pierre-Simon Laplace.

In examining the effects of paternal alcohol consumption on fetal alcohol syndrome, a groundbreaking new study reveals that it can take over a month for negative alcohol effects to wear off.
A University of Toronto undergrad among an international team of researchers unleashing deep learning in the search for extraterrestrial civilizations.
The project is an upscale of a successful pilot built in 2013, and can be expanded further to a network of hubs producing fertiliser for farmer cooperatives.
Researchers from University of Toronto developed an AI system that creates and then sings a Christmas song based by analyzing the visual components of an uploaded image. With the help of CUDA…
A new study led by UCLA Health scientists shows highly creative people’s brains appear to work differently from others;, with an atypical approach that makes distant connections more quickly by bypassing the “hubs” seen in non-creative brains.
I've decided not to work with Aubrey de Grey or SENS in any capacity moving forward. I had one bad experience with him when I was 17 - he told me in writing that he had an ‘adventurous love life’...
Oxidation radically alters everything we perceive in food. It changes the flavor, aroma, color, and texture of everything we eat and drink. Without oxidation, tea would taste unbearably bitter. Oxidation is what unlocks tea’s hidden flavors by removing bitter compounds and transforming flavorless proteins into…
Clifford Algebra, a.k.a. Geometric Algebra, is a most extraordinary synergistic confluence of a diverse range of specialized mathematical fields, each with its own methods and formalisms, all of wh…
An MIT-led study confirms the Antarctic ozone layer is healing as a direct result of global efforts to reduce ozone-depleting substances.
