First a reminder that two of my TED style talks are up. THE FUTURE IS HERE Science meets Science Fiction Imagination, Inspiration and Invention was a lavish event last May in Washington DC, presented by the Smithsonian Magazine in collaboration with the UC San Diego Arthur C. Clarke Center for Human Imagination. Here’s a link to my talk: Otherness: will we supply our own new diversity? (Follow along with the slides on Slideshare!)
Also “Indignation, Addiction and Hope: Does it help to be “Mad as Hell?” My talk at TEDxUCSD finally offers a public version of this disturbing notion I’ve been discussing for years — that an unseen addiction is destroying our civilization. (Follow along with the slides on Slideshare! )
== Innovation will save us ==
You cynics out there had better not read this article about one of the heroes of our age, Dean Kamen, whose new water-distillation machines may provide healthy supplies to hundreds of millions of needy people, slashing disease rates and even preventing war. Kamen’s knack for making money while attacking “impossible problems” goes way back. His FIRST Robotics League has made nerdy inventiveness cool and high-status and fun on thousands of high school campuses. Guys like him — and Elon Musk and Steve Jobs and others — prove that it’s not about left-vs-right. It is about deciding to be confident problem solvers, helping us all to win the positive sum games.
What was the federal government’s role in starting the shale-gas revolution? There is much ado in the press over the arrival (long expected by some of us) of cheap natural gas and renewed supplies of domestic petroleum, developed inside North America. The prospect of U.S. and Canadian energy independence is shaking up political dynamics all over the globe and (among other effects) helping to fuel a new renaissance in American manufacturing.
What seems bizarre is how this has become a crowing point for the Right. The Murdoch-owned Wall Street Journal regularly runs opinion pieces that criticize federal efforts to advance energy technologies and their commercialization… and completely ignore the past federal role in research and stimulation and infrastructure, that made the shale boom possible. See this piece in Physics Today. Can you spell h-y-p-o-c-r-i-s-y?
The gas industry itself has spoken on behalf of federal research efforts. “The DOE started it, and other people took the ball and ran with it,” said Mitchell Energy’s former vice president Dan Steward. “You cannot diminish DOE’s involvement.”
== Inheritance of acquired… nervousness? ==
My colleagues Greg Bear and Mark Anderson have been among those who for years have suggested that Darwinian puritanism blinds us to certain ways that Lamarck might have been at least a little bit right. That some acquired characteristics can be passed to the next generation. Now comes experimental validation of their suspicion… in a way that many of us always knew in our gut. That trauma can get passed down the generations.
See this report: Can We Inherit Fear From Our Parents? In a laboratory experiment, traumatized mice appeared to mature normally. It was only when researchers subjected them to behavioral tests that differences became apparent. The traumatised mice appeared to be reckless, wandering into bright, open spaces that mice usually avoid. Yet they also appeared to be depressed. When placed in a tank of water they gave up and floated instead of trying to swim to safety.
“When males from the traumatised litters fathered offspring, their pups displayed similar abnormal behaviour even though they had never experienced trauma. The pups’ insulin and blood glucose levels were also lower than in normal mice – a symptom of early life stress. The offspring seemed to have inherited the effects of their fathers’ trauma. Furthermore, the next generation, that is the grandchildren of the original stressed mice, also showed abnormal behaviours. How could trauma be transmitted down the generations?
“The researchers analysed the traumatised fathers’ brain tissue, specifically in a region called the hippocampus, where memories are formed. They noticed larger than normal quantities of tiny RNA molecules called microRNA. Like tiny switches, these molecules are known to turn the activity of genes on or off.
“An abundance of this microRNA was also detected in the traumatised fathers’ sperm and in the brain tissue of their offspring. Could it be that the microRNA was somehow imprinted with the experience of the trauma, transmitting the memory to the offspring? To answer this, the researchers extracted the microRNA from the sperm of traumatised mice and injected it into embryos. The pups that developed from these embryos displayed the same behavioural and metabolic abnormalities as the traumatised fathers, while pups injected with RNA from un-traumatised fathers did not. It was strong support for the hypothesis that the sperm RNA was transmitting the experience of trauma.”

A red supergiant that contains, in its bowels, a neutron star? The existence of such an object was first proposed by (my friend) Kip Thorne, an astrophysicist at the California Institute of Technology in Pasadena, and Anna Zytkow, an astrophysicist at the University of Cambridge, UK. Now there is a strong candidate to be an observed Thorne-Zytkow object. Amazing.
Goodbye High Frequency Active Auroral Research Program (HAARP). Conspiracy theorists have accused the program of doing everything from mind control to global communications jamming. Now bulldozers await as the research program (on interesting things, not mind control) wraps up.
Exobiologists surveyed more than 1,000 planets for planet density, temperature, substrate (liquid, solid or gas), chemistry, distance from its central star and age. They developed and computed the Biological Complexity Index (BCI) suggesting 1 to 2 percent of the planets showed a BCI rating higher than Europa, a moon of Jupiter thought to have a subsurface global ocean that may harbor forms of life. With about 10 billion stars in the Milky Way galaxy, the BCI yields 100 million plausible planets. At a glance, it seems a shallow conclusion, in part because Kepler results skew heavily toward massive planets orbiting close to their stars. And because Europa-style moons have no need for a Goldilocks Zone and hence may be pervasive.
Neuroscientists have suspected for some time that the brain has some capacity to direct the manufacturing of new neurons. Now generative neurons that stimulate stem cell production of more neurons have been found.
In The Gap: The Science of What Separates Us from Other Animals. Psychologist Thomas Suddendorf provides a “definitive account of the mental qualities that separate humans from other animals, as well as how these differences arose.” Says Ray Kurzweil: “Drawing on two decades of research on apes, children, and human evolution, he surveys the abilities most often cited as uniquely human—language, intelligence, morality, culture, theory of mind, and mental time travel—and finds that two traits account for most of the ways in which our minds appear so distinct: Namely, our open-ended ability to imagine and reflect on scenarios, and our insatiable drive to link our minds together. These two traits explain how our species was able to amplify qualities that we inherited in parallel with our animal counterparts; transforming animal communication into language, memory into mental time travel, sociality into mind reading, problem solving into abstract reasoning, traditions into culture, and empathy into morality.”
Let Phil Plait show you (and explain) the stunning and strange surface of Saturn’s moon, Phoebe.

HP’s new computer technology can manage 160 petabytes of data in a mere 250 nanoseconds.
‘There is something about the brains of high-IQ individuals that prevents them from quickly seeing large, background-like motions.’ Very interesting re differences in brain function. Interesting grist for deep pondering… or else (as I’ve seen)… we’ll see this used by dogmatists proclaiming “see? Smart people must be stupid!”
A fascinating article in Salon, from the book “Papyrus: The Plant that Changed the World: From Ancient Egypt to Today’s Water Wars” by John Gaudet, describes how the papyrus plant gave ancient Egyptians the ability to make boats and use their water world.
