1:35 PM | Optical features embedded in marine shells may help develop responsive, transparent displays (w/video)
New findings represent the first evidence of an organism using mineralized structural components to produce optical displays. While birds, butterflies, and beetles can display brilliant blues, among other colors, they do so with organic structures, such as feathers, scales, and plates. The limpet, by contrast, produces its blue stripes through an interplay of inorganic, mineral structures, arranged in such a way as to reflect only blue light.

5:38 AM | That old camera in the back of the closet … and other science stories
Old cameras fascinate me. I still have my father’s old Argus C3, my mother’s Kodak Brownie Starmeter, and a couple of vintage Instamatics, among others. Somehow I acquired an Argus 75 box camera and a busted Falcon Miniature — there’s a hole in the latter’s body where the shutter button used to be, so that […]

8:00 PM | Un super buco nero da record ai confini dell’Universo
Un gruppo internazionale di astronomi guidati da Xue-Bing Wu della Peking University hanno confermato l’identificazione di un quasar contenente un buco nero supermassiccio di 12 miliardi di Soli e la cui luminosità supera quella della nostra stella di 420 trilioni di volte. L’oggetto si trova ad una distanza di 12,8 miliardi di anni e si tratta del quasar … Continue reading Un super buco nero da record ai confini dell’Universo →

3:22 PM | Silicon micro-funnels increase the efficiency of solar cells
A biological structure in mammalian eyes has inspired scientists to design an inorganic counterpart for use in solar cells: micron-sized vertical funnels were etched shoulder-to-shoulder in a silicon substrate. Using mathematical models and experiments, they tested how these kind of funnel arrays collect incident light and conduct it to the active layer of a silicon solar cell. Their result: this arrangement of funnels increases photo absorption by about 65 percent in a thin-film solar cell.
