Urinal Design

"What's the best design for splash-free urinal? Physics now has the answer":

Scientists at the University of Waterloo have determined the optimal design for a splash-free urinal: a tall, slender porcelain structure with curves reminiscent of a nautilus shell, playfully dubbed the "Nauti-loo." That's good news for men tired of having urine splash onto their pants and shoes—and for the poor souls who have to regularly clean up all the splatter. Bonus: It's quite an aesthetically appealing design, giving this workhorse of the public restroom a touch of class.

AI Diplomat

"CICERO: An AI agent that negotiates, persuades, and cooperates with people":

Games have long been a proving ground for new AI advancements — from Deep Blue’s victory over chess grandmaster Garry Kasparov, to AlphaGo’s mastery of Go, to Pluribus out-bluffing the best humans in poker. But truly useful, versatile agents will need to go beyond just moving pieces on a board. Can we build more effective and flexible agents that can use language to negotiate, persuade, and work with people to achieve strategic goals similar to the way humans do?

Today, we’re announcing a breakthrough toward building AI that has mastered these skills. We’ve built an agent – CICERO – that is the first AI to achieve human-level performance in the popular strategy game Diplomacy...
