Ecosystem found beneath collapsed Antarctic ice shelf

July 22nd, 2005 | Filed under: Biology, Science | No Comments »

The chance discovery of a vast ecosystem beneath the collapsed Larsen Ice Shelf will allow scientists to explore the uncharted life below Antarctica’s floating ice shelves and further probe the origins of life in extreme environments. Researchers discovered the sunless habitat after a recent underwater video study examining a deep glacial trough in the northwestern Weddell Sea following the sudden Larsen B shelf collapse in 2002.

Allen Brain Atlas

July 17th, 2005 | Filed under: Biology, Health, Mapping, Science | 3 Comments »

Paul G. Allen had a vision that recent advances in computer science, bioinformatics, image analysis and the sequencing of the human genome could be brought together to answer one of the most complex questions in human biology—what is the brain and how does it work? He brought this vision to a renowned group of neuroscientists and advisors, and the Allen Institute for Brain Science was born.
The Allen Brain Atlas is the institutes publicly accessible map of the brain. [launch]

Glass Sponge Skeleton Structure

July 13th, 2005 | Filed under: Biology, Design, Materials, Science | 4 Comments »

John D. Currey, a biologist at the University of York, in England, analyzed Euplectella (Class Hexactinellida), commonly known as glass sponge, and has found “a skeleton of extraordinary structural and mechanical refinement.” It is built in structural levels. Silica particles become filaments, which are formed into spicules, then gathered into larger spicules, which are arranged in a grid with struts and formed into a cylinder, with stiffening surface ridges.

Speech Recognition in 1 Kilobyte

July 6th, 2005 | Filed under: Future, Programming, Science, Technology | 1 Comment »

Russian scientists at the Institute of Radio Engineering and Electronics have identified a new method of speech recognition that picks up only the essential elements needed to decipher each word. Nuances from whispering, shouting, tremors are ignored, allowing for the efficiency of 1 kilobyte to store all numerals and a few basic commands as a prototype for mobile devices.

Extracting Video from the Brain

June 23rd, 2005 | Filed under: Biotech, Future, Mapping, Scary, Science, Technology, Video | 50 Comments »

Garret B. Stanley’s article, published in 1999 in the Journal of Neuroscience, outlines how activity of neurons can be decoded into a reconstructed image. Stanley claims the decoding algorithm is simple since each point in space can be reconstructed at high resolutions from 6 to 8 pairs of cells. The more neurons are tracked, the higher the quality of the reconstruction. The following still frames from a video (top) are actual reconstructions (bottom) from the activity of 177 cells in a cat’s brain.
