The flight of a bee

November 28th, 2005 | Filed under: Biology, Mechanical Tech, Video | 1 Comment »

Michael Dickinson and his colleagues filmed hovering bees at 6000 frames per second, and plotted the unusual pattern of wing beats. The wing sweeps back in a 90˚ arc, then flips over as it returns – an incredible 230 times a second. The team made a robot to scale to measure the forces involved.

Q Machine : One million atom simulation

November 7th, 2005 | Filed under: Biology, Biotech, Computing, Future | 3 Comments »

Researchers at Los Alamos National Laboratory have set a new world’s record by performing the first million-atom computer simulation in biology. Using the “Q Machine� supercomputer, Los Alamos computer scientists have created a molecular simulation of the cell’s protein-making structure, the ribosome. The project, simulating 2.64 million atoms in motion, is more than six times larger than any biological simulations performed to date. [press release]

Morphology database going global

October 16th, 2005 | Filed under: Biology, Future, Mapping | No Comments »

Morphbank is an open web repository of images serving the biological research community. It is currently being used to document specimens in natural history collections, to voucher DNA sequence data, and to share research results in disciplines such as taxonomy, morphometrics, comparative anatomy, and phylogenetics. With a $2.25 million NSF grant, Fredrik Ronquist and his team at Florida State University hope to eventually have a database accessible by everyone from kindergarteners to researchers with user friendly features such as image recognition to identify the species of an organism from a user-uploaded photograph.

Non-Invasive Brain-Computer Interface

September 28th, 2005 | Filed under: Biology, Computing, Future, Virtual Reality | 1 Comment »

Brain-computer interfaces (BCI), like the one developed at the Graz University of Technology in Austria, places electrodes in key locations on the user’s scalp to detect nerve activity which is then translated to walking or movement of the virtual character’s hands. The team at the Graz University of Technology have incorporated a fully immersive Virtual Cave for a mind bending walk by thinking. [nature article]

Self-Assembling Viral Battery

September 26th, 2005 | Filed under: Biology, Biotech, Fabrication Tech, Future, Materials, Nanotech, Science | 3 Comments »

Dr. Angela Belcher and her group at MIT are developing an organic-inorganic hybrid method of growing batteries. By forcing viruses to interact with materials like metals, Dr. Belcher is exploring new materials that are self assembling with a high degree of control based on the chosen DNA sequence. Imagine selecting DNA for any type of material you want the virus to grow. [Discover Article]

Sensing Babies Counting

September 22nd, 2005 | Filed under: Biology, Health, Mathematics | No Comments »

Dr. Andrea Berger and her colleagues are continuing Dr. Karen Wynn’s study on young babies and their grasp on mathematical concepts. Berger connected her 50 baby subjects to a ‘geodesic-net’ sensor cap, that measures the electrical activity produced by the brain. “Babies can process quantity data very, very early in life and can even perform very basic mathematical operations like addition and subtraction.” Using the ‘geodesic-net’ ERP (event-related potential) tool she is “able to identify the exact millisecond when the baby is presented with an impossible event, and we can examine the brainwaves and the pattern of activity.”

Nano Computing

September 7th, 2005 | Filed under: Biology, Computing, Future, Nanotech, Science, Technology | 18 Comments »

“Computing isn’t just confined to semiconductors. Molecules have been processing information ever since life has been around on our planet. Harnessing this remarkable ability really does have the potential to make a big difference to people’s lives.” For the first time, chemists at Queen’s University Belfast, with funding from the Engineering and Physical Sciences Research Council (EPSRC) have managed to manipulate molecules to perform logic operations based on the principles of photosynthesis.
