Jeff Hudson in Full Stop: Here is something I know: I feel better when I read — not just good, but better. Anxieties are assuaged, burdens lightened, relationships enriched. I feel part of something hopeful, a connection to the writer, the characters, other readers.Science - News for Your Neurons | Wired.com
Photo: Joe Pugliese There is one version of Craig Venter’s life story where he would’ve been a dutiful scientist at the National Institutes of Health, a respected yet anonymous researcher in genetics, perhaps. Thankfully, Venter saw that story line developing—and set about making sure it never happened.arXiv blog - Technology Review
One of the hot topics in computer science is the study of unconventional forms of computation. This is motivated by two lines of thought. The first is theoretical--ordinary computers are hugely energy inefficient--some eight orders of magnitude worse than is theoretically possible. The second is practical--Nature has evolved many much more efficient forms of computation for specific tasks such as pattern recognition. Clearly, we ought to be able to do much better--hence the interest in different ways of doing things. Various groups have tried computing with exotic substances such as chemicals like hot ice and even with a single celled organism called a slime mould .The Selvedge Yard

Of all the discoveries of ancient man, none made a greater impact on humanity than fire. Although fire was certainly developed independently by many groups, its discovery is none the less one of the greatest moments in mankind becoming what we are today. Without fire there could be no cooking, no warmth beyond what nature or body heat can provide, no light after dark. Fire was man’s first discovery that allowed the utilization of energy on demand. It would later drive our engines, smelt our metals and even propel rockets to the moon and beyond.climate change blogs
Physicist : There are several algorithms, but almost all of them are all based on “trap-door encryption”. The idea is that you find some kind of mathematical process that’s easy to run forward, but effectively impossible to run backward, unless you know a trick (which you keep secret). It’s likened to a trap-door because (as every super-villain knows) it’s easy to go through a trap-door in one direction, but difficult in the other. This is fundamentally different from the encoding schemes most people are familiar with, like “A=2, B=15, C=…” or Igpa Atinla , which are called “substitution cyphers”. If you know how a substitution cipher is done, then you can not only encode a message, but you can decode it.
