Go figure! Game victory seen as artificial intelligence milestone

In what they called a milestone achievement for artificial intelligence, scientists said on Wednesday they have created a computer program that beat a professional human player at the complex board game called Go, which originated in ancient China. The feat recalled IBM supercomputer Deep Blue's 1997 match victory over chess world champion Garry Kasparov. "Go is considered to be the pinnacle of game AI research," said artificial intelligence researcher Demis Hassabis of Google DeepMind, the British company that developed the AlphaGo program.

Artificial Intelligence Beats 'Most Complex Game Devised by Humans'

An artificial intelligence system has defeated a professional Go player, cracking one of the longstanding grand challenges in the field. What's more, the new system, called AlphaGo, defeated the human player by learning the game from scratch using an approach known as "deep learning," the researchers involved say. Ever since IBM's Deep Blue defeated Gary Kasparov in their iconic chess match in 1997, AI researchers have been quietly crafting robots that can master more and more human pastimes.

1-in-a-Million Odds Link Global Warming and Record Heat

For 2014 alone, there's a one-in-a-million chance that the monster heat record occurred only from natural climate variability. "The risk of heat extremes has been multiplied due to human greenhouse-gas emissions, as our data analysis shows," study co-author Stefan Rahmstorf said in a statement. "The anomalous warmth has led to unprecedented local heat waves across the world, sadly resulting in loss of life and aggravating droughts and wildfires," said Rahmstorf, a professor at the Potsdam Institute for Climate Impact Research in Germany.

New Foldable Battery Takes Cue from Chinese Calligraphy

Scientists in China have developed a flexible, rollable, foldable battery inspired by traditional Chinese calligraphy involving ink on paper. Worldwide demand for flexible electronics is rapidly growing, because the technology could enable such things as video screens and solar panels to bend, roll and fold.

All US Adults Should Be Screened for Depression, Panel Recommends

All adults in the U.S., including pregnant and postpartum women, should be screened for depression when they visit the doctor, according to new recommendations released by a government-appointed panel. This recommendation from the U.S. Preventive Services Task Force (USPSTF) is largely consistent with the group's previous recommendation, which was issued in 2009, said Karina Davidson, a member of the task force and a professor at Columbia University Medical Center. The USPSTF makes recommendations regarding the effectiveness of preventive health services, and also considers whether the benefits of treatments outweigh the potential risks.

Can Your BMI Predict How Long You'll Live?

Body mass index (BMI) is a common measure of body fat, but new research shows that having a BMI in the "normal weight" range is not always the healthiest for every person. In fact, for many people, having a BMI in the overweight range may be linked with the lowest risk of dying over a 13-year period, the research suggests. Usually, a BMI below 18.5 is considered underweight, from 18.5 to 24.9 is considered normal weight, from 25 to 29.9 is considered overweight, and 30 and over is considered obese.
