AI Reaches the Golden Years

July 21, 2006

Artificial intelligence is 50 years old this summer, and while computers can beat the world’s best chess players, we still can’t get them to think like a 4-year-old. This week in Boston, some of the field’s leading practitioners are gathering to examine this most ambitious of computer research fields, which at once has managed to exceed, and fall short of, our grandest expectations.

Molecular DNA Switch Found to be the Same for All Life

July 21, 2006

The molecular machinery that starts the process by which a biological cell divides into two identical daughter cells apparently worked so well early on that evolution has conserved it across the eons in all forms of life on Earth. Researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California at Berkeley have shown that the core machinery for initiating DNA replication is the same for all three domains of life – Archaea, Bacteria and Eukarya.

Earth faces ‘catastrophic loss of species’

July 21, 2006

Life on earth is facing a major crisis with thousands of species threatened with imminent extinction – a global emergency demanding urgent action. This is the view of 19 of the world’s most eminent biodiversity specialists, who have called on governments to establish a political framework to save the planet. The planet is losing species faster than at any time since 65 million years ago, when the earth was hit by an enormous asteroid that wiped out thousands of animals and plants, including the dinosaurs.

The Universe Within

July 21, 2006

View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons.

Marvin Minsky on Common Sense and Computers That Emote

July 16, 2006

Top computer scientists from around the world are meeting today at Dartmouth College in Hanover, NH, to mark the 50th anniversary of “artificial intelligence.” Back in 1956, John McCarthy, then a member of Dartmouth’s mathematics faculty, invented the term for the field’s seminal gathering, the Dartmouth Summer Research Project on Artificial Intelligence. McCarthy and four other participants in the 1956 project, including MIT’s Marvin Minsky, are participating in this week’s meeting, which focuses on AI’s next 50 years.

This Is a Computer on Your Brain

July 16, 2006

A new brain-computer-interface technology could turn our brains into automatic image-identifying machines that operate faster than human consciousness. Researchers at Columbia University are combining the processing power of the human brain with computer vision to develop a novel device that will allow people to search through images ten times faster than they can on their own.

tagthe.net

July 13, 2006

What is this? tagthe.net is a webservice intended to provide you with tags for your texts. You can use it in your applications, in other webservices or just play around with it. Why is it so different? In contrast to other services it uses the information that is present in the text, it analyses the content and tries to find out words that could be useful as tags. Currently it works with english, german and french texts.
