Tetris effect

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[edit] The Tetris effect can occur with other video games.[2] 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 recent Friday night, 30 men and 30 women gathered at a hotel restaurant in Washington, D.C. Their goal was love, or maybe sex, or maybe some combination of the two. Google Begins Testing Its Augmented-Reality Glasses. Self-sculpting sand. Imagine that you have a big box of sand in which you bury a tiny model of a footstool.

Self-sculpting sand

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. The Poetry of Science: Richard Dawkins and Neil deGrasse Tyson. How the Potato Changed the World. 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.

Study Finds Alcohol and Tobacco More Harmful than Marijuana, LSD, or Ecstasy (Revisited) : The Scientific Activist

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. Psychology and Feminism - Final Published 2011.pdf. When Truisms Are True. Biggest Scientific Breakthroughs of 2011. IBM's "neurosynaptic" chips are the closest thing to a synthetic brain yet. A nice, clear, and mostly correct statement.

However, you are forgetting one thing: Those in power wish to stay in power. Those who have power wish to have more power. And those who have property that could suddenly not be "theirs" would be highly resistant to relinquishing said property. Online gamers have managed to solve a decade-old scientific puzzle.

Sci-ence! A Skeptical Comic and Blog.

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. 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.

Researchers evolve a multicellular yeast in the lab in 2 months

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.

BBC Nature - Chimpanzees consider their audience when communicating. 29 December 2011Last updated at 17:01 By Victoria Gill Science reporter, BBC Nature The chimps made soft "hoo" sounds to warn individuals that had not seen the threat Chimpanzees appear to consider who they are "talking to" before they call out.

Researchers found that wild chimps that spotted a poisonous snake were more likely to make their "alert call" in the presence of a chimp that had not seen the threat. This indicates that the animals "understand the mindset" of others. Cagebreak! Rats Will Work To Free A Trapped Pal. Hide captionA new study finds that rats will intentionally work to free a trapped pal. Calling someone a "rat" is no compliment, but a new study shows that rats actually are empathetic and will altruistically lend a helping paw to a cage mate who is stuck in a trap.

Cagebreak! Rats Will Work To Free A Trapped Pal

Not only will rats frantically work to free their trapped cage mate; they will do so even when there's a tempting little pile of chocolate chips nearby, the study reveals. Instead of leaving their pal in the trap and selfishly gobbling the candy all by themselves, rats will free their cage mate and share the chocolate. "To me that's absolutely stunning," says neurobiologist Peggy Mason of the University of Chicago. Breathingearth - CO2, birth & death rates by country, simulated real-time.

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.

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.
