Speech/music development in birds

Great piece on Fresh Air the other day on bird sounds. Includes info. on bioacoustics and how birds learn their songs.

On March 29, Terri Gross interviewed Donald Kroodsma, specialist in the interpretation of bird songs. His new book, The Singing Life of Birds: The Art and Science of Listening to Birdsong, describes how birds communicate and why. She also talked to Don Stap, an ornithologist. His new book Birdsong, details the work and passions of people who analyze the sounds of birds. Stap followed Kroodsma from the lab into the field to write his account of the researcher at work.

Cool Video Site

Check out Open-Video.org!

The content includes 30-60 minute movies from the early 1900s (including silent films!), almost 500 documentaries from NASA, the Digital Himalaya Project from the 1930s, advertisements from the 1950s, CHI materials from the Ass'n for Computing Machinery, and television PSAs for reproductive health in Yemen.

There are some great educational videos appropriate for use in schools, especially in the sciences. There are a handful of entries on the word "brain", and many animated films.

The search is very good -- you can limit to color, b&w, by length, and silent or with sound. The majority of these images are either in the public domain or otherwise available for educational use, but check the Copyright Statement for more information.

Warning: you may spend a lot of time at this site!

A New Company to Focus on Artificial Intelligence

March 24, 2005
Technology: A New Company to Focus on Artificial Intelligence
New York Times
By JOHN MARKOFF
The technologist and the marketing executive who co-founded Palm Computing
are starting a new company to license software technologies based on a
theory of how the mind works.

" ... Jeff Hawkins and Donna Dubinsky will remain involved with what is now called PalmOne, but on Thursday they plan to announce the creation of Numenta, a technology development firm that will conduct research in an effort to extend Mr. Hawkins's theories. Those ideas were initially sketched out last year in his book "On Intelligence: How a New Understanding of the Brain Will Lead to the Creation of Truly Intelligent Machines," co-written with Sandra Blakeslee."

Why do cats purr?

I posed this question to Brain Boost last week, and I can't stop thinking about the (possible) answer. It's not really current news, but it's so interesting I'm posting it anyway:

"A purring cat is not necessarily a happy one; many species-including cheetahs and some lions-also purr when wounded or anxious. Some researchers speculate that this lovely rumble may serve a function: to heal fractures and strengthen bones. In an as yet unpublished study from the Fauna Communications Research Institute in Hillsborough, N.C., investigators determined that the frequency at which many cats purr, between 27 and 44 hertz for house cats, matches the frequency that seems to help human bones strengthen and grow. If correct, the theory may explain why cats heal so quickly after injury." -Scientific American; June2001, Vol. 284 Issue 6, p32.

I can't find the study (I think it's still unpublished), but you can read more about it in this Scientific American article (Hampshire only at that URL).

Lexicographers: the next generation

BrainBoost: Very cool natural language search engine

BrainBoost is a new natural language search engine that seems to work pretty well. You can browse answers to questions like "What is a Calorie" (in the Nutrition category) and "How Much Profit Did Google Have in 2004" (in the Business category) and you can also ask your own. My research indicats that it properly identified Amherst as one place where Uma Thurman lived while growing up. And it provided lots of sites explaining why cats purr, including many which suggest that cats purr in part to help their bones and muscles grow strong.

For the computer scientists among you, "Brainboost uses Machine Learning and Natural Language Processing techniques to go the extra mile, by actually answering questions, in plain English."

The logo's great, too. (Thanks to Tara Calishain's ResearchBuzz for this cool time-waster)

How Emotional Memories are Stored

Report of an interesting study at Duke on how emotional memories are stored long term.

Tuesday, March 8, 2005 | DURHAM, N.C. -- Researchers exploring the brain structures involved in recalling an emotional memory a year later have found evidence for a self-reinforcing "memory loop" -- in which the brain's emotional center triggers the memory center, which in turn further enhances activity in the emotional center.
