DR Congo Ring May Be Giant Impact Crater 96

Phrogman writes "The BBC is reporting that deforestation has 'revealed what could be a giant impact crater in Central Africa, scientists say. The 36-46km-wide feature, identified in DR Congo, may be one of the largest such structures discovered in the last decade.' If you search Google Maps for 'Omeonga Democratic Republic of the Congo,' you will be right in the middle of the suspected crater."

Measuring the Speed of Light With Valentine's Day Chocolate 126

Cytotoxic writes "What to do with all of those leftover Valentine's Day chocolates? — a common problem for the Slashdot crowd. The folks over at Wired magazine have an answer for you in a nice article showing how to measure the speed of light with a microwave and some chocolate. A simple yet surprisingly accurate method that can be used to introduce the scientific method to children and others in need of a scientific education."

Comment Re:How is daytrading not gambling? (Score 1) 300

It's your third point where you go wrong,

Neither creates wealth and merely shifts it around

more daytraders means more participants in the market place, more participants means more liquidity and more liquidity means a better functioning market place. A market with no liquidity, is a market that is not trading, ie the 2008 market, where bids and offers are worlds apart, this is bad for ALL the participants from big institutions to small retail guy, much like you I presume... Hence daytraders, while you may not realize it are providing a service for the market place at their own risk and are compensated accordingly.

Chevy Volt Rated At 230 mpg In the City 1006

necro81 writes "General Motors, emerging from bankruptcy, today announced that its upcoming plug-in hybrid vehicle, the Volt, will have an EPA rating of 230 mpg for city driving (about 98 km/L). The unprecedented rating, the first in triple digits, is the result of a new (draft) methodology for calculating the 'gas' mileage for vehicles that operate primarily or extensively on electricity. The Volt, due out late next year, can drive approximately 40 miles on its Li-Ion battery pack, after which a gasoline engine kicks in to provide additional electricity to charge the battery. Running off the gasoline engine yields approximately 50 mpg. Of course, the devil's in the details, because the conversion of grid-based electricity to gasoline-mileage is imprecise." Now we know the meaning of the mysterious "230" viral marketing campaign.

Free Realms Approaches the Five-Million-Player Mark 77

A few days ago at Comic-Con, Sony Online Entertainment president John Smedley spoke about the success of Free Realms, their free-to-play MMORPG that relies on microtransactions for a business model. The game was released at the end of April, and by mid-June there were upwards of three million registered users. Now that total is approaching five million, with no sign of slowing down. Min Kim, another panelist at the discussion, said, "When people started talking about it back in 2003 or 2004, people said Western games would never want to do this, to play a game for free and then buy items. And now everybody is saying, 'We're going to have microtransactions as part of our business model.'"

Abel Mebratu writes with this excerpt from the BBC: "The first undersea cable to bring high-speed internet access to East Africa has gone live. The fiber-optic cable, operated by African-owned firm Seacom, connects South Africa, Tanzania, Kenya, Uganda and Mozambique to Europe and Asia. The firm says the cable will help to boost the prospects of the region's industry and commerce. The cable — which is 17,000km long — took two years to lay and cost more than $650m."
