People who play video puzzle games like this for a long time may see moving images like this at the edges of their visual fields, when they close their eyes, or when they are drifting off to sleep. The Tetris effect (also known as Tetris Syndrome) occurs when people devote so much time and attention to an activity that it begins to pattern their thoughts, mental images, and dreams. It is named after the video game Tetris. Other examples The Tetris effect can occur with other video games. It has also been known to occur with non-video games, such as the illusion of curved lines after doing a jigsaw puzzle, or the involuntary mental visualisation of Rubik's Cube algorithms common amongst speedcubers. On a perceptual level, sea legs are a kind of Tetris effect.

A few seconds later, you reach into the box and pull out a full-size footstool: The sand has assembled itself into a large-scale replica of the model. That may sound like a scene from a Harry Potter novel, but it’s the vision animating a research project at the Distributed Robotics Laboratory (DRL) at MIT’s Computer Science and Artificial Intelligence Laboratory.

Study Finds Alcohol and Tobacco More Harmful than Marijuana, LSD, or Ecstasy (Revisited) : The Scientific Activist. Back in August, I reported on an ACMD study buried in the back of a UK government report.
The study gave strong evidence that the current drug classification scheme in the UK was fundamentally flawed and was not based on the actual danger of a given drug. The study has now been published in this week’s issue of The Lancet. Homepage.psy.utexas.edu/homepage/group/busslab/pdffiles/Evolutionary Psychology and Feminism - Final Published 2011.pdf.

I mean the concept of ‘nothing’. We used to be able to say things like ‘the vast nothingness of space” and have an idea of what that meant. But we know there is, in fact, lots of ‘things’ in between the regular ‘stuff’ in space. Dark matter, dark energy, virtual particles, the fabric of spacetime itself. These are things we cannot get rid of without stepping outside the known boundaries of our universe.
So why is there something rather than nothing? Today’s comic might seem familiar if you remember this previous wonder-of-science episode. ROBO-ONE 13: Taekwon-V vs. Garoo. Researchers evolve a multicellular yeast in the lab in 2 months. When we think of life on Earth, most of us think of multicellular organisms, like large mammals or massive trees.
But we're only aware of three groups of complex, multicellular organisms, which suggested it might be a major hurdle. Now, a new study describes how researchers evolved a multicellular form of yeast (the same species that contributes to bread and beer), and were able to see specialized cell behaviors and reproduction in as little as 60 days. The authors lay out the problem very simply in their introduction, stating that, "Multicellularity was one of the most significant innovations in the history of life, but its initial evolution remains poorly understood.
" There is some evidence that it can be a favorable trait—research shows that clusters of cells evolve when a single-celled organism is kept in culture with a predator that can only swallow one cell at a time. But that's about as far as these experiments went. Their method was pretty simple. Are smart people ugly? The Explainer's 2011 Question of the Year.

Blindness eased by historic stem cell treatment - health - 25 January 2012. For the first time since they were discovered 13 years ago, human embryonic stem cells (hESCs) have shown medical promise.
Two people with eye degeneration both say their vision improved in the four months after they received implants of retinal pigment epithelial cells made from hESCs. The treatments were also safe, with no sign that the cells triggered aggressive tumours called teratomas, no sign of immune rejection of the cells, and no inflammation. Discovered in 1998, hESCs had previously failed to deliver on their medical promise. Features of a successful therapeutic fast of 382 days' duration.

My Man, Sir Isaac Newton. NASA Beams Beatles' 'Across the Universe' Into Space. NASA Beams Beatles' 'Across the Universe' Into Space For the first time ever, NASA beamed a song -- The Beatles' "Across the Universe" -- directly into deep space at 7 p.m. EST on Feb. 4. The transmission over NASA's Deep Space Network commemorated the 40th anniversary of the day The Beatles recorded the song, as well as the 50th anniversary of NASA's founding and the group's beginnings. Two other anniversaries also are being honored: The launch 50 years ago this week of Explorer 1, the first U.S. satellite, and the founding 45 years ago of the Deep Space Network, an international network of antennas that supports missions to explore the universe.
The transmission was aimed at the North Star, Polaris, which is located 431 light years away from Earth. "Amazing!
