"A new three-dimensional imaging technique has revealed spiraling movements that had previously only been inferred from two-dimensional data. [This is the] first large-scale, high-resolution recordings of human sperm in three dimensions, tracking more than 1,500 cells over several hours. Human sperm have eluded such detailed observation in the past. Their heads are just 3–4 micrometers long and can only be seen under high magnification, but the cells zoom around at up to 100 micrometers per second, ducking in and out of focus or darting out of range in an instant."Hmm, camera shy or eggs-tremely focused?-)
"...a revolutionary new category of Robot [...] capable of applying common sense behavior to manufacturing environments. Affordably priced, versatile and safe enough to work shoulder-to-shoulder with people, Baxter robots redefine how small, mid-size and large domestic manufacturers use automation to compete with manufacturers in low-cost regions of the world."
"...uses two small speakers to generate sound waves at frequencies slightly above the audible range – roughly 22 kilohertz. When the top and bottom speakers are precisely aligned, they create two sets of sound waves that perfectly interfere with each other, setting up a phenomenon known as a standing wave. At certain points along a standing wave, known as nodes, there is no net transfer of energy at all. Because the acoustic pressure from the sound waves is sufficient to cancel the effect of gravity, light objects are able to levitate when placed at the nodes."
