Transhumanism
Timothy Leary — transhumanism with a SMI2LEJune 9, 2013 by R.U. Sirius Most people know Timothy Leary as the “LSD guru” who encouraged people to “Turn On, Tune In, Drop Out” in the 1960s. But a surprising number of transhumanist types don’t know that he was one of them. In fact, Leary may have been the first to signal a memeplex for the transhuman future — SMI2LE (Space Migration Intelligence Increase and Life Extension) — back in the mid-1970s. My new book, Timothy Leary’s Trip Thru Time, explores Leary’s life and philosophies, including his transhuman explorations. Here’s an excerpt ... mais »
Human brain C-14 dating
Atomic bombs help solve mystery: does the adult human brain produce new neurons?June 9, 2013 Radioactive carbon-14 atoms released by atomic bomb tests are helping scientists determine new neurons produced in the brain (credit: Spalding et al./Cell) A study in the journal *Cell* reveals that a significant number of new neurons in the hippocampus — a brain region crucial for memory and learning — are generated in adult humans. “It was thought for a long time that we are born with a certain number of neurons, and that it is not possible to get new neurons after birth,” says senior study... mais »

The color scheme ranges from green (least subjected to surveillance) through yellow and orange to red (most surveillance). Note: the “2007″ date in the image relates to the document from which the interactive map derives its top secret classification, not to the map itself. (Credit: The Guardian)
ONLINE COURSES
Do online courses spell the end for the traditional universityPublishing, music, shopping, journalism – all revolutionised by the internet. Next in line? Education. Now US academics are offering world-class tuition – free – to anyone who can log on, anywhere in the world, is this the end of campus life?

Biological clock
Scientists map the wiring of the biological clock Changing sleep cycles can cause cancer and other disorders June 10, 2013 (Credit: iStockphoto) The connections make the clock precise but also let it adjust to changes in day/night cycles. The World Health Organization lists shift work as a potential carcinogen, says Erik Herzog, PhD, Professor of Biology in Arts & Sciences at Washington University in St. Louis. And that’s just one example among many of the troubles we cause ourselves when we override the biological clocks in our brains and pay attention instead to the mechanical clocks... mais »
Feeding 9 billion people?
How do you feed 9 billion people?June 11, 2013 *[+]* (Credit: Michigan State University) An international team of scientists has developed crop models to better forecast food production to feed a growing population — projected to reach 9 billion by mid-century — in the face of climate change. In a paper appearing in Nature Climate Change, Members of the Agricultural Model Intercomparison and Improvement Projectunveiled an all-encompassing modeling system that integrates multiple crop simulations with improved climate change models. AgMIP’s effort has produced new knowledge that better... mais »
NMDA receptors
A new neurochemical pathway for treating schizophrenia and age-related mental declineJune 11, 2013 [image: Activated_NMDAR] Depiction of an activated NMDA receptor (credit: Delldot/Wikimedia Commons) Researchers at Boston University School of Medicine(BUSM) have uncovered important clues about a biochemical pathway in the brain that may one day expand treatment options for schizophrenia. This research focused on key components of the brain known as NMDA receptors. These receptors are located on nerve cells in the brain and serve as biochemical gates that allow calcium ions (electrical ... mais »
Rapamicin
Lifespan-extending drug given late in life reverses age-related heart disease in miceJune 12, 2013 [image: Lightmatter_lab_mice] Laboratory mice (credit: Lightmatter/Wikimedia Commons) Elderly mice suffering from age-related heart disease saw a significant improvement in cardiac function after being treated with the FDA-approved drug rapamycin for just three months. The research, led by a team of scientists at the Buck Institute for Research on Aging, shows how rapamycin impacts mammalian tissues, providing functional insights and possible benefits for a drug that has been shown to ex... mais »

Astrobiologists find Martian clay contains chemical implicated in the origin of lifeJune 12, 2013 *[+]* Electron microscope image showing the 700-million-year-old Martian clay veins containing boron (100 µm = one tenth of a millimeter) (credit: UHNAI) Researchers from the University of Hawaii at Manoa NASA Astrobiology Institute (UHNAI) have discovered high concentrations of boron in a Martian meteorite. When present in its oxidized form (borate), boron may have played a key role in the formation of RNA, one of the building blocks for life. The work was published on June 6 in open-acc... mais »
Online learning

In April, Stanford and edX, the nonprofit online learning enterprise founded by Harvard and MIT, announced they would collaborate on future development of the edX online platform. As part of that effort, edX has released the … more…
Restoring Sight
A simple, non-invasive gene therapy restores sight Can now safely insert repair genes into photoreceptors in the fine-vision fovea June 14, 2013 To evolve a virus best suited for gene therapy, Berkeley researchers created more than 100 million engineered adeno-associated viruses (left) and injected them into the gel-like center of the eye. Those able to penetrate the many cell layers of the retina are used to shuttle a corrective gene into cells containing a defective gene. To reach these cells, in particular the light-sensitive photoreceptors and the retinal pigment epithelium (RPE)... mais »
Supercomputer memory

The Blue Brain Project, for example, is building detailed models of the rodent brain based on vast amounts of information — incorporating experimental data and a large number of parameters — to describe each neuron and how they connect to each ... mais »
Einstein: The Secret to Learning Anything
The Secret to Learning Anything: Albert Einstein's Advice to His Son *"That is the way to learn the most, that when you are doing something with such enjoyment that you don’t notice that the time passes."* With Father's Day around the corner, here comes a fine addition to history's greatest letters of fatherly advice from none other than *Albert Einstein* – brilliant physicist, proponent of peace, debater of science and spirituality, champion of kindness – who was no stranger to dispensing epistolary empowerment to young minds.

Unprecedented Wealth
Unprecedented Wealth, Debt Slavery and Conditioned Consciousness By David DeGraw Global Research, June 06, 2013 daviddegraw.org Region: USA Theme: Global Economy, Poverty & Social Inequality Introduction Seventeen years ago, I read a book called The Evolving Self. Though I didn’t realize it at the time, it profoundly affected the direction of my life. Here’s the section of the book that became a splinter in my mind and resonated the most with me: *“In order to gain control of consciousness, we must learn how to moderate the biases built into the machinery of the brain. We allow a whole ... mais »
