A Robot’s Body of Knowledge

Early risers may think it’s tough to fix breakfast first thing in the morning, but robots have it even harder. Even grabbing a cereal box is a challenge for your run-of-the-mill artificial intelligence (AI). Frosted Flakes come in a rectangular prism with colorful decorations, but so does your childhood copy of Chicken Little. Do you need to teach the AI to read before it can grab breakfast?

Maybe not. A team of European researchers has built a robot called ARMAR-III, which tries to learn not just from previously stored instructions or massive processing power but also from reaching out and touching things. Consider the cereal box: By picking it up, the robot could learn that the cereal box weighs less than a similarly sized book, and if it flips the box over, cereal comes out. Together with guidance and maybe a little scolding from a human coach, the robot—the result of the PACO-PLUS research project—can build general representations of objects and the actions that can be applied to them. “[The robot] builds object representations through manipulation,” explains Tamim Asfour of the Karlsruhe Institute of Technology, in Germany, who worked on the hardware side of the system.

Straight talk with…Leonor Beleza

Portuguese businessman António Champalimaud surprised his family when his will, opened after his 2004 death, revealed that he was bequeathing euro500 million ($690 million), about a quarter of his estate, to establish a foundation for applied biomedical research. He also surprised law professor and one-time Portuguese Health Minister Leonor Beleza, whom he named to lead the foundation. Beleza, who met Champalimaud just once, agreed in principle to run his proposed foundation during a phone call in 2000 but did not hear any further until his death. She has now returned from a global tour of medical research institutions and foundations lasting over a year to determine how best to spend Champalimaud’s millions.

Narwhals transmit climate data from Arctic seas

The cold water beneath the winter pack ice in Baffin Bay is getting warmer, according to measurements taken by thermometer-wearing narwhals. The data collected from the diving mammals fill in a geographical and seasonal gap in the region’s climate records, as no winter temperatures were previously available from the area. The data also confirm that a warming trend measured during earlier summer-only studies of the West Greenland Current continued in the three years to 2007.

“We basically knew nothing about winters up in Baffin Bay,” says physical oceanographer Mike Steele at the University of Washington in Seattle, who co-authored the study, which appeared last week in the Journal of Geophysical Research. “But there is a lot of interest in the flow of seawater around Greenland.”

Sugar beets still in the game

Seed producers will be allowed to plant biotech sugar beets again following a September decision from the United States Department of Agriculture’s crop approval arm to allow planting under interim guidelines. The Animal and Plant Health Inspection Service (APHIS) will issue limited permits to seed developers authorizing genetically modified (GM) beet planting this fall as long as the harvested beets are not allowed to flower. The permits are a legal way around a federal judge’s 13 August decision to ban all commercial farming of Monsanto’s Genuity Roundup Ready sugar beets beyond that date.
