If you're having a hard time visualizing the Big Bang, let Columbia University astronomy and physics professor Janna Levin show you how it all started. In this first-rate animation that shows the Big Bang more concisely than I've ever seen, the professor makes an important point about the origin of our doughnut-shaped universe: Before the Big Bang, there was no space or time. There was nothing. That huge explosion didn't happen in space — it happened in the middle of nothing.

Can you imagine being able to produce enough water in the Sahara to grow crops there? Can you imagine harnessing sufficient quantities of solar power to supply electricity to cities in Africa and cities in Europe? Can you imagine producing a sustainable bio-fuel that doesn’t impact on world food supplies? Charlie Paton, Michael Pawlyn and Bill Watts can and what’s more they can imagine all these happening in the same place at the same time.

Just in case you didn't think judgement day was comming... Scientist preform an experiment where robots are suppose to work together to find a resourcedesigned to cooperate in searching out a beneficial resource and avoiding a poisonous one learned to lie to each other in an attempt to hoard the resource. Picture a robo-Treasure of the Sierra Madre.
The experiment involved 1,000 robots divided into 10 different groups. Each robot had a sensor, a blue light, and its own 264-bit binary code "genome" that governed how it reacted to different stimuli. The first generation robots were programmed to turn the light on when they found the good resource, helping the other robots in the group find it.
The robots got higher marks for finding and sitting on the good resource, and negative points for hanging around the poisoned resource. The 200 highest-scoring genomes were then randomly "mated" and mutated to produce a new generation of programming. Within nine generations, the robots became excellent at finding the positive resource, and communicating with each other to direct other robots to the good resource.
However, there was a catch. A limited amount of access to the good resource meant that not every robot could benefit when it was found, and overcrowding could drive away the robot that originally found it.
After 500 generations, 60 percent of the robots had evolved to keep their light off when they found the good resource, hogging it all for themselves. Even more telling, a third of the robots evolved to actually look for the liars by developing an aversion to the light; the exact opposite of their original programming!

A groundbreaking new loudspeaker, less than 0.25mm thick, has been developed by University of Warwick engineers, it's flat, flexible, could be hung on a wall like a picture, and its particular method of sound generation could make public announcements in places like passenger terminals clearer, crisper, and easier to hear. Lightweight and inexpensive to manufacture, the speakers are slim and flexible: they could be concealed inside ceiling tiles or car interiors, or printed with a design and hung on the wall like a picture.
Pioneered by University of Warwick spin-out company, Warwick Audio Technologies' the 'Flat, Flexible Loudspeaker' (FFL) is ideal for public spaces where it delivers planar directional sound waves, which project further than sound from conventional speakers.
Steve Couchman, CEO of Warwick Audio Technologies, believes it could entirely replace the speakers currently used in homes and in cars, as well as in public address systems used in passenger terminals and shopping centres.
He says: "We believe this is a truly innovative technology. Its size and flexibility means it can be used in all sorts of areas where space is at a premium. Audio visual companies are investigating its use as point of sale posters for smart audio messaging and car manufacturers are particularly interested in it for its light weight and thinness, which means it can be incorporated into the headlining of cars, rather than lower down in the interior."
All speakers work by converting an electric signal into sound. Usually, the signal is used to generate a varying magnetic field, which in turn vibrates a mechanical cone, so producing the sound.
Warwick Audio Technology's FFL technology is a carefully designed assembly of thin, conducting and insulating, materials resulting in the development of a flexible laminate, which when excited by an electrical signal will vibrate and produce sound.
The speaker laminate operates as a perfect piston resonator. The entire diaphragm therefore radiates in phase, forming an area source. The wave front emitted by the vibrating surface is phase coherent, producing a plane wave with very high directivity and very accurate sound imaging.
"Another great application would be in PA systems for public spaces," says Steve. "The sound produced by FFLs can be directed straight at its intended audience. The sound volume and quality does not deteriorate as it does in conventional speakers, which means that public announcements in passenger terminals, for example, could be clearer, crisper, and easier to hear."
Future space hotel moguls can get nervous when NASA's next-generation spaceship plans begin to founder. So one company has come up with a modified "Lite" design of the planned Orion vehicle to carry astronauts and paying passengers into orbit.Bigelow Aerospace has long envisioned launching inflatable space station called Sundancer, and so improving passenger access to low Earth-orbit has remained a priority.
The company has already quietly briefed a White House-appointed panel on its suggested design. Space News reports that Bigelow has also received help from prime Orion contractor Lockheed Martin.
Bigelow's modified Orion design would eliminate the propellant tanks and robust heat shields necessary for a moon mission, and instead only aim for low Earth-orbit. An unusual landing system would also involve midair retrieval after atmospheric reentry, rather than the typical ocean splashdown. NASA and the military have previously used such midair capture techniques with helicopters.
The weight savings of Orion Lite could allow launch of a human-rated Orion aboard an existing Atlas 5 rocket within three or four years, instead of NASA's shaky original deadline of 2015.
One Bigelow officer even mentioned that the modified Orion could also launch aboard SpaceX's Falcon 9 rocket.
PopSci previously took a grand tour of Bigelow's orbital space modules that could someday house high-flying space tourists. But no word yet on whether future Orion passengers would get mints inside their space helmets.

Electromagnetic pulse is hardly a household term. But perhaps it should be. Every computer we buy, every system we turn over to computer control, every device that relies on electronic components — all cars, TVs and phones, for instance — makes us more vulnerable to such a high-energy rain of electrons.
EMP is a powerful and potentially devastating form of electromagnetic "fallout." It’s usually associated with nuclear weapons, although it can be triggered by any major explosive bursts. Unlike radioactive fallout, this rain won’t directly harm living things. It will just catastrophically fry all electronics and modern electrical systems by inducing staggeringly large and rapid current or voltage surges.Read the full story here

Move over, silicon -- it may be time to give the Valley a new name. Physicists at the Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have confirmed the existence of a type of material that could one day provide dramatically faster, more efficient computer chips.

I was on popsci.com and I found this article on making small adjustments to make your home more green. They had some interesting easy fixes to save some money on your electric bill.
The article was done in a reader like format that I haven't seen. The software was called Zinio. If anyone has heard of it.. Comment. It made reading it more interactive(a little confusing) and over all it was a good experience.
Here is the link CLICK
P.S. it asks you for your name and email, but you can put whatever you want. I put in my real one though and haven't gotten any spam from it.

Yesterday we showed you how to make your own tonic water, but if you're more of an active type, why not make your own sports drink as well? The New York Times has a simple recipe that shows you how.
Photo by madaise.
The Times' Well blog dedicated a post to determining whether sports drinks are good for kids (answer: it depends). The article ends with the following recipe—a modified version of our previously featured DIY sports drink concoction. To make yours, you'll need the following ingredients:
1/4 cup sugar
1/4 teaspoon salt
1/4 cup orange juice
1/4 cup hot water
2 tablespoons lemon juice
3 1/2 cups cold water
As for the preparation, dissolve the sugar and salt in the hot water (using a quart pitcher), then add in the remaining ingredients and cold water. According to the NYT, "the drink contains about 50 calories and 110 mg of sodium per 8 ounces, approximately the same as for most sports drinks."

General Motors calls the Chevrolet Volt an extended-range electric vehicle. That's because the only motive force comes from the electric motor; the gas engine only charges the batteries. In a press conference earlier today, GM's CEO Fritz Henderson said the Volt will have a city mileage figure of 230 miles per gallon--almost five times more efficient than a Prius. But considering the uniqueness of the Volt's powertrain, how did the EPA get that figure?Click here for the full story

The Studies“Resveratrol Improves Health and Survival of Mice on a High-Calorie Diet,” Nature, 2009
The HypeMorley Safer interviewed the founders of Sirtris, a company planning a pill form of resveratrol, a compound found in red wine. He ended up doing a lot of cheerleading. Among the untested claims the show let slide: that a pill could forestall diseases in our 50s, 60s and 70s, and that it works using the body’s natural defenses against Alzheimer’s, cancer and diabetes.
The Subtler TruthThough it’s often a paragon of journalistic rigor, 60 Minutes has a record of falling short on health issues. Its breathless 13-minute coverage of resveratrol, which has been tested mostly on mice and yeast, presented no opposing view and was tempered only by a single (and damning) statistic: “9 out of 10 drugs that look good in mice ultimately fail in human trials.” Says Gary Schwitzer, a professor at the University of Minnesota and founder of journalism watchdog site HealthNewsReview.org, “The job they’ve done on health and medical-science stories makes me watch the rest of their stories with greater scrutiny. Sometimes journalists become enamored and fawning about the progress of science. They check their skepticism at the door.”
The Bottom LineThere seems to be some sort of connection between heart health and red wine, but it’s not clear that resveratrol is why. And considering that plenty of animal tests don’t credit resveratrol, one has to wonder at all the puffery. When it comes to surprising health claims, even the much-vaunted 60 Minutes needs to be viewed with a critical eye.
ConclusionI think that even if it doesn't do anything maybe if I believe in it I will have a placebo affect. Hey its worth a try. If you want to buy the supplement they have it at GNC or Amazon and its not expensive.

Though whispers of an Apple tablet device practically predate Australopithecus, this week they’ve reached a fever pitch. It’s been reported by several news outlets that the supposed iTablet will feature a 10-inch touchscreen, both Wi-Fi and 3G data, and a custom ARM processor. It’s already been priced at $800 and even greenlit by none other than His Majesty Steve Jobs for a September release. Not one iota of this has been officially confirmed, but the prospect of a Mac Tablet seems more within reach than ever before.
This is not a good thing. If an Apple tablet is ever actually released, we should all be very concerned for the future of what most of us take for granted today: our digital freedom.
