Douglas Hofstadter's Lonely Quest to Create Artificial Intelligence that is Truly Intelligent. Literal Smart Dust Opens Brain-Computer Pathway to “Spy on Your Brain” Source: Activist Post Some might have heard about Smart Dust; nanoparticles that can be employed as sensor networks for a rangeof security and environmental applications.
Now, however, literal Smart Dust for the brain is being proposed as the next step toward establishing a brain-computer interface. The system is officially called “neural dust” and works to “monitor the brain from the inside.” Inventors are attempting to overcome the hurdle of how to best implant sensors that can remain over the course of one’s life. Researchers at Berkeley Engineering believe they have found a novel way to achieve this: This paper explores the fundamental system design trade-offs and ultimate size, power, and bandwidth scaling limits of neural recording systems. A network of tiny implantable sensors could function like an MRI inside the brain, recording data on nearby neurons and transmitting it back out. EtcML - Home. Human Evolution Timeline Interactive.

In New Quantum Experiment, Effect Happens Before Cause. September 19, 2013 - A real-world demonstration of a thought experiment conducted at the University of Vienna, has produced a result that is somewhat befuddling to people with what the lead researcher calls a "naïve classical world view.
" Two pairs of particles are either quantum-entangled or not. One person makes the decision as to whether to entangle them or not, and another pair of people measure the particles to see whether they're entangled or not. The head-scratcher is: the measurement is made before the decision is made, and it is accurate. "Classical correlations can be decided after they are measured," says Xiao-song Ma, the writer of the study.
Entanglement can be created "after the entangled particles have been measured and may no longer exist. " The finding can be integrated into potential quantum computers, one hopes. Quantum mechanics allows for some very strange things, like the teleportation of information and computers that can break even the toughest codes. Antikythera mechanism. The Antikythera mechanism (Fragment A – front) The Antikythera mechanism (Fragment A – back) The Antikythera mechanism (/ˌæntɨkɨˈθɪərə/ ANT-i-ki-THEER-ə or /ˌæntɨˈkɪθərə/ ANT-i-KITH-ə-rə) is an ancient analog computer[1][2][3][4] designed to predict astronomical positions and eclipses.
It was recovered in 1900–1901 from the Antikythera wreck, a shipwreck off the Greek island of Antikythera.[5] Although the computer's construction has been attributed to the Greeks and dated to the early 1st century BC, its significance and complexity were not understood until the 1970s when it was analyzed with modern X-ray technology. Technological artifacts approaching its complexity and workmanship did not appear again until the 14th century, when mechanical astronomical clocks began to be built in Western Europe.[6] The mechanism was housed in a wooden box approximately 340 × 180 × 90 mm in size and comprised 30 bronze gears (although more could have been lost). Origins and discovery[edit] NASA: Discovery opens door to search for new life forms. News December 2, 2010 03:58 PM ET Computerworld - NASA scientists have found a new form of bacteria that they say has changed their notion of life as we've known it.
Researchers said during a press conference Thursday that they found a strange microbe in Mono Lake in Northern California. Unlike every other known microorganism, these bacteria are able to survive and reproduce using arsenic, a toxic chemical. It's a matter of substitution, according to Felisa Wolfe-Simon, a NASA astrobiology research fellow. "It's a microbe doing something different than life as we've known it," said Wolfe-Simon. Today's news will push back most of the speculation that has been rampant on the Internet since NASA said several days ago that it would have an astrobiology announcement Thursday. The announcement wasn't about alien life but instead focused on a different form of life right here on Earth. Phosphorus, which aids in carrying energy in all cells, is considered an essential element for all living cells.
More data storage? Here's how to fit 1,000 terabytes on a DVD. We live in a world where digital information is exploding.
Some 90% of the world’s data was generated in the past two years. The obvious question is: how can we store it all? In Nature Communications today, we, along with Richard Evans from CSIRO, show how we developed a new technique to enable the data capacity of a single DVD to increase from 4.7 gigabytes up to one petabyte (1,000 terabytes). This is equivalent of 10.6 years of compressed high-definition video or 50,000 full high-definition movies. So how did we manage to achieve such a huge boost in data storage? The basics of digital storage Although optical discs are used to carry software, films, games, and private data, and have great advantages over other recording media in terms of cost, longevity and reliability, their low data storage capacity is their major limiting factor.
