How Bacteria Turn Fiber into Food
Most people think of fiber as being the part of our food we can’t digest—but with the help of symbiotic bacteria in our guts, we can actually get some nutrition from the complex carbohydrates such as cellulose, hemicellulose, and pectin that make up plants’ cell walls. The bacteria produce an arsenal of enzymes that break down these carbs into simple sugars, which are then in turn fermented to ...
متن کاملHow Did Dinosaur Bones Turn Into Fossils?
If fossilization was simply replacement of bone with stone, fossil and living bones wouldn't be as chemically similar as they are, and the intricate details found in fossilized dinosaur bones would not have survived [1]. Even more intriguing is the fact that some of the proteins in bone have survived the fossilization process, in dinosaurs and "older" fossils [2], a fact very consistent with a ...
متن کاملSonoluminescence: How Bubbles Turn Sound into Light
Sonoluminescence, the transduction of sound into light, is a phenomenon that pushes fluid mechanics beyond its limit. An initial state with long wavelength and low Mach number, such as is realized for a gas bubble driven by an audible sound field, spontaneously focuses the energy density so as to generate supersonic motion and a different phase of matter, from which are then emitted picosecond ...
متن کاملHow to Turn the Reaction Coordinate into Time
What are the internal motions of an ion channel protein when it “gates” between closed and open-channel conformations? In 2005, Zhou, Pearson, and Auerbach (ZPA) (Biophys. J. 89:3680–3685) showed that Φ, a parameter derived from the forward and backward rate constants of a chemical reaction, may in some cases provide temporal information about the moving parts of a protein. This “primer” is int...
متن کاملHow to turn Light into Matter in LHC?
Dark energy is a mysterious force that pervades all space, acting as a "push" to accelerate the universe's expansion. Despite being 70 percent of the universe, dark energy was only discovered in 1998 by two teams observing Type Ia supernovae. A Type 1a supernova is a cataclysmic explosion of a white dwarf star. The best way of measuring dark energy just got better, thanks to a new study of Type...
