FIRST (For Inspiration and Recognition of Science and Technology) has robot competitions all over the United States. FIRST was founded by inventor Dean Kamen. According to Wikipedia he has said that the FIRST competition is the invention he is most proud of, and he predicts that the 1 million students who have taken part in the contests so far will be responsible for some significant technological advances in years to come. In any case, Robert Rozeboom (samzenpus) was at the Michigan FIRST championship with camcorder in hand, and brought back some great shots of robots at work -- or maybe play. They fired off volleys of Frisbee-like discs, ran into each other, and climbed metal pyramids, either independently or under the control of their human masters. There was a pretty good crowd in the stands, too, to cheer on the robots. Or more likely, to cheer on the robots' human masters, since we're not yet at the point where robot masters invite their robot friends to competitions where they show off their humans.

DoctorBit writes "MIT Technology Review is running a story about an arXiv paper in which geneticists Alexei A. Sharov and Richard Gordon propose that life as we know it originated 9.7 billion years ago. The researchers estimated the genetic complexity of phyla in the paleontological record by counting the number of non-redundant functional nucleotides in typical genomes of modern day descendants of each phylum. When plotting genetic complexity against time, the researchers found that genetic complexity increases exponentially, just as with Moore's law, but with a doubling rate of about once every 376 million years. Extrapolating backwards, the researchers estimate that life began about 4 billion years after the universe formed and evolved the first bacteria just before the Earth was formed. One might image that the supernova debris that formed the early solar system could have included bacteria-bearing chunks of rock from doomed planets circling supernova progenitor stars. If true, this retro-prediction has some interesting consequences in partly resolving the Fermi Paradox. Another interesting consequence for those attempting to recreate life's origins in a lab: bacteria may have evolved under conditions very different from those on earth."

ananyo writes with this bit about lab grown organs from Nature: "Scientists at Massachusetts General Hospital in Boston have fitted rats with kidneys that were grown in a lab from stripped-down kidney scaffolds. When transplanted, these 'bioengineered' organs starting filtering the rodents' blood and making urine. The team, led by organ-regeneration specialist Harald Ott, started with the kidneys of recently deceased rats and used detergent to strip away the cells, leaving behind the underlying scaffold of connective tissues such as the structural components of blood vessels. They then regenerated the organ by seeding this scaffold with two cell types: human umbilical-vein cells to line the blood vessels, and kidney cells from newborn rats to produce the other tissues that make up the organ (paper)."
