Korean carbon-coated lithium-ion battery could cut recharge times down to minutes
Anyone who's had to recharge an EV -- or, for that matter, any mobile device with a very big battery -- knows the pain of waiting for hours while a lithium-ion pack tops up. South Korea's Ulsan National Institute of Science and Technology has developed a conduction technique that could cut that charging time down to less than a minute. By dousing the nanoparticle materials of the battery in a graphite solution that's then carbonized, the researchers make a web of conductors that all start charging at once; current batteries have to charge towards the center slowly, like a not-very-edible Tootsie Pop. The immediate goal is to develop a secondary battery for an EV that could provide extra mileage in a matter of seconds. Here's hoping that the Ulsan team's fast-charging battery is more viable than others and spreads to just about everything -- we'd love to have EVs and laptops alike that power up in as much time as it takes to fill a traditional car at the pump.

Three hours and out: South Korea considers additional gaming ban for minors
It looks like being a young gamer in South Korea is getting tougher and tougher. Last year the country put into effect a "Cinderella Law" that prohibited online gamers 18 and younger from logging in to popular games between the hours of midnight and 6:00 a.m.. Now the government is taking a close look at an additional law limiting the amount of time played each day for minors. The proposed policy comes from the Ministry of Education, Science and Technology (MEST) and would yank account privileges for minors if they played either more than two hours in a row or more than three hours daily. The MEST is concerned about game addiction in minors, citing that it may come from the duration of play sessions. The game industry is concerned about possible over-regulation by the government spurred by theories on addiction that haven't been proven. Some are calling for earlier shutdown policies to be overturned if this one is implemented.
