Scientists create the most complex map yet of an insect brain's 'wiring'
Scientists have created the most advanced "circuit map" of the brain so far, with a price wiring diagram of a fruit fly larva.
Google helps publish the largest high-res map of brain connectivity
A joint effort between Google and the Janelia Research Campus has just achieved a significant breakthrough in brain mapping. They've published the largest high-resolution map of brain connectivity to date, offering a 3D model of 25,000 fruit fly neurons across a diverse range of cell types and multiple brain regions. The team achieved the feat by cutting sections of the fly's brain into ultra-thin (20-micron) slices, imaging those pieces with electron streams from a scanning electron microscope and stitching them back together. The result is a sophisticated map with so few disruptions that it's practical to trace neurons through the brain.
Genetic engineering lets fruit flies 'smell' light
Scientists in Germany have genetically engineered fruit fly larva to 'smell' blue light -- and apparently it smells like bananas! According to a paper published in Frontiers in Behavioral Neuroscience, researchers at Ruhr-Universitaet-Bochum were able to splice a gene for a light-activated protein into cells in the olfactory system. Depending on which cell was spliced, the larva perceived the blue light as smelling like anything from bananas to marzipan or even glue. The scientists used thin electrodes to detect the light-activated neurons, and it is hoped that research in this area will lead to similar procedures that don't harm living animals. Now that they've perfected modding Drosophila larvae, the scientists say they'd like to move on to adult fruit flies. Which is cool with us -- just as long as they don't repeat Seth Brundle's mistakes.
Mad scientists figure out how to write memories to brains, take over Earth
Call us crazy, but we're guessing one Gero Miesenböck of the University of Oxford has been watching just a wee bit too much Fringe. Gero here, along with a few of his over-anxious colleagues, has seemingly figured out a way to actually write memories onto a fruit fly's brain using only a laser pen and three-fourths of a Ouija board. We know what you're thinking, and we're thinking the same. But all terrifying thoughts aside, what if boffins could burn memories of hard lessons learned into our minds without us having to suffer through them first? You know, like upgrading to Snow Leopard.
Fruit fly flight simulator could smarten up robots
Wondering just how we mere mortals were going to even give a robot enough smarts to completely overtake our societies? Oddly enough, some of that artificial brain power could come from studying the way fruit flies, um, fly. A completely bizarre flight simulator at Caltech actually plays "scenes" that flys react to, and considering that the fly is constantly held, researchers can closely examine how the insect attempts to navigate away from lines, blobs and all manners of incoming obstacles. Those working with the installation suggest that these studies could one day help autonomous robots function better, potentially taking some of the load off of our human workforce. We know, you've got three bold letters and a question mark running through your noggin right now -- just hit the read link to see what it's all about.[Thanks, Dave]
