I won't speculate on the intentions of OC. But bringing up oil does raise a very legitimate item of concern. For much of the 20th century, petroleum has been the critical resource that drove or enabled much of our civilization and technical infrastructure. If we are going to look skyward, we have *GOT* to start thinking differently about the resource(s) that we are going to use. Unless big oil is willing to shell out the cash for researching the exploration and mining of hydrocarbons in the Jovian system, our government has got to step up and look at what we need to power space travel on an industrial scale.

I don't think we're talking about the same things. Post-9/11, plenty of cool things have been done by talented IT professionals for the government in the name of national security. If it was desired badly enough, it was made to happen. I don't think cultural differences was much of an impediment that got us to the point we are today.

Having skimmed through the article, it seems to me the elephant in the room is being ignored. A much more compelling case can be made for the fact that too *much* information technology already at the disposal of the government is making it way too easy to abuse the American public. It isn't a question of funding, it is a question of priorities.

The videos of Feynman speaking at Cornell that Gates acquired and released are NOT the more popularly known "Feynman Lectures on Physics". It was part of the Messanger Lectures series where Feynman was a guest at his alma mater. Entitled "The Character of Physical Law", they are lesser known, but more accessible to someone who isn't intent upon a complete college lecture course.

+ - Lose Sleep, Fail to Form Memory 1

Submitted by Rambo Tribble
Rambo Tribble (1273454) writes "A research team of Chinese and American scientists claim to have witnessed the mechanism by which sleep contributes to the formation of memories. Using advanced microscopy the researchers witnessed synapses being formed in the brain of sleeping mice recently exposed to a learning task. They compared this to similarly tasked mice, that were subsequently sleep-deprived. The sleeping mice showed a marked increase in the formation of new synapses. As one researcher explained, 'We thought sleep helped, but it could have been other causes, and we show it really helps to make connections and that in sleep the brain is not quiet, it is replaying what happened during the day and it seems quite important for making the connections.'

+ - Redemption of a forgotten Astronomy Hero

Submitted by StartsWithABang
StartsWithABang (3485481) writes "In the 1800s, British astronomer John Couch Adams spent his life devoted to explaining the minor orbital deviations of the then-newly discovered planet, Uranus. But despite his best efforts to find the theoretical new planet responsible, he was scooped by the French theorist Urbain Le Verrier. To make matters worse, Adams sported one of the worst combovers in photographic history! But everyone gets a shot at redemption, and for Adams, discovering the origin of meteor showers and growing an epic beard saw him make good on both of those counts. Happy 195th birthday to one of astronomy's (and history's) forgotten heroes!"

+ - Fasting triggers stem cell regeneration of damaged, old immune system->

Submitted by schwit1
schwit1 (797399) writes "In the first evidence of a natural intervention triggering stem cell-based regeneration of an organ or system, a study in the June 5 issue of the Cell Stem Cell shows that cycles of prolonged fasting not only protect against immune system damage — a major side effect of chemotherapy — but also induce immune system regeneration, shifting stem cells from a dormant state to a state of self-renewal.

In both mice and a Phase 1 human clinical trial, long periods of not eating significantly lowered white blood cell counts. In mice, fasting cycles then “flipped a regenerative switch,” changing the signaling pathways for hematopoietic stem cells, which are responsible for the generation of blood and immune systems, the research showed.

“PKA is the key gene that needs to shut down in order for these stem cells to switch into regenerative mode. It gives the OK for stem cells to go ahead and begin proliferating and rebuild the entire system,” “And the good news is that the body got rid of the parts of the system that might be damaged or old, the inefficient parts, during the fasting. Now, if you start with a system heavily damaged by chemotherapy or aging, fasting cycles can generate, literally, a new immune system.”"

Submitted by Lasrick
Lasrick (2629253) writes "This is a heartbreaking read that profiles Amor Masovic, who works for the Bosnian government's Missing Persons Institute. Masovic traverses the "Valley of Death," the Drina River basin, looking for the mass graves of people (mostly Muslim men) killed during the genocide of the Bosnian war: 'For Masovic, the massacre in Srebrenica presents a special professional challenge. Only about a thousand of those fleeing were killed outright. The other 7,000 were captured and taken to various killing fields for execution, their bodies dumped into mass graves. Shortly afterward, however, Serb commanders ordered the original graves dug up and the remains moved to a series of smaller mass graves along the Drina River basin — the so-called Valley of Death — that they hoped would never be found. “This has made Srebrenica our greatest challenge,” Masovic said.'"

Those stats reflect a lot of corporate negligence, but individuals aren't innocent, either. About 11 million people fell for email phishing scams and 29 percent had their PCs infected by malware. And despite frequent media reports about such attacks, 62 percent of us have done virtually nothing to toughen our security.

Most problems can be avoided by taking a few small actions: using difficult-to-guess passwords and not re-using them, avoiding websites of dubious origin, not posting private info on social networks and not clicking on unknown email attachments, for starters.""
