Analysts said it would happen. Professor Stephen Hawking said it should happen. And now it has. Peter Higgs, the man who first predicted the existence of the Higgs boson, or ‘God particle’, has been given a Nobel Prize for his efforts along with Belgian physicist Francois Englert.

Nuclear fusion, the same process that powers the sun, could provide us with limitless cheap energy—but experiments to date have always used more power than they created. Now, though, researchers have apparently tipped that balance, making fusion a real possibility.

If you’ve ever put gas in a car, you’ll know that the pump magically knows when to stop spewing fuel into the tank. That’s super useful, and safe too. But how does it know when to stop?

The European Organization for Nuclear Research aka CERN reached the attention of the masses when they finished the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator. Physicists and other scientists all over the world have high hopes for the LHC, while the rest of us are thoroughly impressed with its name. Now you can be even more vaguely impressed with cutting edge technology, thanks to Google’s Street View tour of the CERN site.
The tour is the final product of a two-week shoot by Google’s crew back in 2011. They took images of 5 different areas of CERN’s facilities, including nearly 4,000ft of the LHC tunnel. Check all of them out on Google Maps. Be sure to nod approvingly as you gaze at the images. Doing that helped me resist passing out from sheer confusion.
Particle accelerators range in size from massive to compact, but researchers from Stanford University and the SLAC National Accelerator Laboratory have created one that’s downright miniscule. What you see above is a specially patterned glass chip that’s smaller than a grain of rice, but unlike a broken Coke bottle, it’s capable of accelerating electrons at a rate that’s roughly 10 times greater than the SLAC linear accelerator. Taken to its full potential, researchers envision the ability to match the accelerating power of the 2-mile long SLAC linear accelerator with a system that spans just 100 feet.
For a rough understanding of how this chip works, imagine electrons that are brought up to near-light speed and then concentrated into a tiny channel within the glass chip that measures just a half-micron tall. From there, infrared laser light interacts with patterned, nanoscale ridges within the channel to create an electrical field that boosts the energy of the electrons.
In the initial demonstration, researchers were able to create an energy increase of 300 million electronvolts per meter, but their ultimate goal is to more than triple that. Curiously enough, these numbers aren’t even that crazy. For example, researchers at the University of Texas at Austin were able to accelerate electrons to 2 billion electronvolts over an inch with a technique known as laser-plasma acceleration, which involves firing a laser into a puff of gas. Even if Stanford’s chip-based approach doesn’t carry the same shock and awe, it seems the researchers are banking on its ability to scale over greater distances. Now if we can just talk them into strapping those lasers onto a few sharks, we’ll really be in business.

The latest science news out of Harvard and MIT sounds like a joke, but it’s not. A team of physicists were fooling around with photons when they managed to get the particles to clump together to form a molecule, one that’s unlike any other matter. And it behaves, they say, just like a lightsaber.

Get your notebooks out, class is about to start. Nerds are cool….nothing else to say here.
If this entire planet, solar system and galaxy just doesn’t hold enough excitement for you, be prepared to pick up some speed—because scientists have worked out that you need to be travelling at a staggering 1.2 million mph to exit the Milky Way.

Thanks to improvements in fiber optics, most of the information that you consume on any given day is transported by light. Quite inefficiently, however, most computer chips need electricity to operate, and scientists haven’t quite figured out how to make the leap to more futuristic materials. At least not until graphene came along.
