Life is just that slice of toast, you have morning noon or night. The years go by and our goals wrapped up in our dreams become a review of what we must change.
We are set on our path with the seeds planted over time which become our reference list of right and wrong. This list is the most important list and must be reviewed and corrected, because the information seeds we received from family, friends, education and relationships may be seeds of misguided good and are not the seeds we need to take root. Not all seeds are bad. Not all seeds are good. Happy New Year.
We investigate fundamental decisions in the design of instruction set architectures for linear genetic programs that are used as both model systems in evolutionary biology and underlying solution representations in evolutionary computation. We subjected digital organisms with each tested architecture to seven different computational environments designed to present a range of evolutionary challenges. Our goal was to engineer a general purpose architecture that would be effective under a broad range of evolutionary conditions. We evaluated six different types of architectural features for the virtual CPUs: (1) genetic flexibility: we allowed digital organisms to more precisely modify the function of genetic instructions, (2) memory: we provided an increased number of registers in the virtual CPUs, (3) decoupled sensors and actuators: we separated input and output operations to enable greater control over data flow. We also tested a variety of methods to regulate expression: (4) explicit labels that allow programs to dynamically refer to specific genome positions, (5) position-relative search instructions, and (6) multiple new flow control instructions, including conditionals and jumps. Each of these features also adds complication to the instruction set and risks slowing evolution due to epistatic interactions. Two features (multiple argument specification and separated I/O) demonstrated substantial improvements in the majority of test environments, along with versions of each of the remaining architecture modifications that show significant improvements in multiple environments. However, some tested modifications were detrimental, though most exhibit no systematic effects on evolutionary potential, highlighting the robustness of digital evolution. Combined, these observations enhance our understanding of how instruction architecture impacts evolutionary potential, enabling the creation of architectures that support more rapid evolution of complex solutions to a broad range of challenges.
Nice visual on differences in income, with associated paper. No stats needed here; a simple exploratory/observational curiosity is all you need. A great starter for classroom discussions/lab activities. Start with this primer where you can see the distinct difference.
Some of the most common causes of bad breath are the most obvious ones. You know it's time to brush when you've had some particularly garlicky shrimp scampi or you practically breathe fire first thing in the morning.
Kickstarter just announced via its Twitter account that it will be opening up its crowdfunding platform for Canada-based projects as of “later this summer.” Thus far, that’s as specific as the company is getting, but anyone interested in finding out more can sign up at Kickstarter’s Canada launch page with their email and project category of interest to get an alert when things go live.
The virtual currency is about more than money – the real innovation is what people are doing with the technology it is based on
BITCOIN has been called many things, from the future of money to a drug dealer's dream and everything else in between. But beyond creating the web's first native currency, the true innovation of Bitcoin's mysterious designer, Satoshi Nakamoto, is its underlying technology, the "block chain". That fundamental concept is being used to transform Bitcoin – and could even replace it altogether.
So what is the block chain? It is a ledger of transactions that keeps Bitcoin secure and allows all users to agree on exactly who owns how many bitcoins. Each new block requires a record of recent transactions along with a string of letters and numbers, known as a hash, which is based on the previous block and produced using a cryptographic algorithm.
Miners, people who run the peer-to-peer Bitcoin software, randomly generate hashes, competing to produce one with a value below a certain target difficulty and thus complete a new block and receive a reward, currently 25 bitcoins. This difficulty means faking a transaction is impossible unless you have more computing power than everyone else on the Bitcoin network combined. Confused? Don't worry, ordinary Bitcoin users needn't know the details of how the block chain works, just as people with a credit card don't bother learning banking network jargon. But those who do understand the power of the block chain are realising how Nakamoto's technology for mass agreement can be adapted. "You can replace that agreement with all sorts of different things and now you have a really powerful building block for any kind of distributed system," says Jeremy Clark of Concordia University in Montreal, Canada.
Unconscious impulses and desires impel what we think and do in ways Freud never dreamed of
When psychologists try to understand the way our mind works, they frequently come to a conclusion that may seem startling: people often make decisions without having given them much thought—or, more precisely, before they have thought about them consciously. When we decide how to vote, what to buy, where to go on vacation and myriad other things, unconscious thoughts that we are not even aware of typically play a big role. Research has recently brought to light just how profoundly our unconscious mind shapes our day-to-day interactions.
Dr. Angela Belcher, a materials chemist and one of the world’s leading scientists in nanotechnology was announced today as the recipient of the 2013 $500,000 Lemelson-MIT Prize.
Belcher has drawn inspiration from nature and its ability to create materials.
-She believes that if organic and inorganic materials can combine in nature to produce exquisite structures, similar processes can be used in the lab to create things of which nature hasn’t yet dreamed. She has used these lessons in biology to design novel, hybrid organic-inorganic materials that have been used to create environmentally-friendly batteries and clean transportation fuel, among other inventions with both commercial and social value. The Lemelson-MIT Prize, which honors an outstanding mid-career inventor dedicated to improving our world through technological invention, has been awarded annually since 1995.
