Quarks Know Their Left From Their Right 150

sciencehabit writes "How an electron interacts with other matter depends on which way it's spinning as it zips along—to the right like a football thrown by a right-handed quarterback or the left like a pigskin thrown by a lefty. Now, physicists have confirmed that quarks—the particles that join in trios to form the protons and neutrons in atomic nuclei—exhibit the same asymmetry. The result could give physics a new weapon in the grand hunt for new particles and forces. Or they can search for subtle hints of exotic new things beyond their tried-and-true standard model by studying familiar particles in great detail. In the latter approach, the new experiment gives physicists a way to probe for certain kinds of new forces."

Second World War Code-cracking Computing Hero Colossus Turns 70 110

DW100 writes "The Colossus computer that helped the Allies crack messages sent by the Nazis during the Second World War has celebrated its 70th birthday. The machine was a pioneering feat of engineering, able to read 5,000 characters a second to help the team at Bletchley Park crack the German's Lorenz code in rapid time. This helped the Allies gather vital information on the Nazi's plans, and is credited with helping end the war effort early, saving millions of lives."

Build an Open-Source Electric Car In About One Hour 188

First time accepted submitter joe5 writes "Like what Elon Musk has done and want to go all Etsy and build your own electric car? That's apparently now possible now thanks to the OSVehicle Tabby — dubbed the first "Open source vehicle" (memo: it may be cool, but it ain't the first). The OSV guys are taking pre-orders for the Tabby starter kit, with both the two-seater or four-seater configurations going for €500. Then you click to add options. (Note: seats is an "option" so that's the level of luxury you are dealing with here.) When the transaction's complete, OSV sends the parts to your home and you can download the plans and start building. Since the Tabby is open source, OSVehicle will also look to a community of owners and tinkerers for suggestions and recommendations."

Cooking With Your USB Ports 188

tekgoblin writes "Wow, I would never have thought to try and cook food with the power that a standard USB port provides, but someone did. A standard port provides 5V of power, give or take a little. I am not even sure what it takes to heat a small hotplate, but I am sure it is more than 5V. It looks like the guy tied together around 30 USB cables powered by his PC to power this small hotplate. But believe it or not, it seems to have cooked the meat perfectly."

Experts Closing In On Google Attack Coders 141

ancientribe writes "The targeted attacks out of China that hit Google, Adobe, and other US organizations are still ongoing and have affected many more companies than the original 20 to 30 reported. Security experts now say they are getting closer to identifying the author or authors of the malware used to breach Google and other organizations."

Comment Re:Four dimensions (Score 2, Insightful) 180

I'm sure it's my mathematics background, but when I saw the headline I assumed the author would be discussing something involving the square root of negative one, to which my response was, "Silly author, you can't visualize four dimensions. (Sober.)"

You have a mathematical background and can not visualize four dimensions? Here is how you do it: Just visualize the problem in n dimensions and then set n=4.
