Drunk History Presents Nikola Tesla *NSFW* 91

Amazingly accurate for someone so plastered. I think all history should be taught at this level of intoxication.

The Best Robots of 2009 51

kkleiner writes "Singularity Hub has just unveiled its second annual roundup of the best robots of the year. In 2009 robots continued their advance towards world domination with several impressive breakouts in areas such as walking, automation, and agility, while still lacking in adaptability and reasoning ability. It will be several years until robots can gain the artificial intelligence that will truly make them remarkable, but in the meantime they are still pretty awesome."

Alabama Wages War Against the Perfect Weed 360

pickens writes "Dan Berry writes in the NY Times that the State of Alabama is spending millions of dollars in federal stimulus money to combat Cogongrass, a.k.a. the perfect weed, the killer weed, and the weed from another continent. A weed that 'evokes those old science-fiction movies in which clueless citizens ignore reports of an alien invasion.' Cogongrass (Imperata cylindrica) is considered one of the 10 worst weeds in the world. 'It can take over fields and forests, ruining crops, destroying native plants, upsetting the ecosystem,' writes Berry. 'It is very difficult to kill. It burns extremely hot. And its serrated leaves and grainy composition mean that animals with even the most indiscriminate palates — goats, for example — say no thanks.' Alabama's overall strategy is to draw a line across the state at Highway 80 and eradicate everything north of it; then, in phases, to try to control it to the south. But the weed is so resilient that you can't kill it with one application of herbicide, you have to return several months later and do it again. 'People think this is just a grass,' says forester Stephen Pecot. 'They don't understand that cogongrass can replace an entire ecosystem.' Left unchecked, Pecot says 'it could spread all the way to Michigan.'"

Researchers Discover How To Make the Perfect Phone Call 85

Having made amazing discoveries such as how to make the perfect cheese sandwich, linking heavy caffeine use to sleeplessness, and figuring out where all the teaspoons have gone, science has made the greatest breakthrough yet. They have uncovered the secrets of making the perfect phone call. The perfect phone call clocks in at a mere 9 minutes and 36 seconds, easily 11 minutes shorter than any conversation I've ever had with my mom. Unlike a call to mom, the perfect phone call is almost devoid of any gossip about her divorced neighbor and her heavily tattooed daughter. Instead three minutes should be spent catching up with news about family and friends, one minute on personal problems, a minute on work/school, 42 seconds on current affairs, 24 seconds on the weather, and 24 seconds talking about the opposite sex. What's left of your 9 mins 36 secs is a free for all.
