Arctic Rocks Offer New Glimpse of Primitive Earth
Scientists have discovered a new window into the Earth’s violent past. Geochemical evidence from volcanic rocks collected on Baffin Island in the Canadian Arctic suggests that beneath it lies a region of the Earth’s mantle that has largely escaped the billions of years of melting and geological churning that has affected the rest of the planet. Researchers believe the discovery offers clues to the early chemical evolution of the Earth.
For the First Time Ever, Scientists Watch an Atom’s Electrons Moving in Real Time
An international team of scientists led by groups from the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany, and from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California at Berkeley has used ultrashort flashes of laser light to directly observe the movement of an atom’s outer electrons for the first time.

Long-sought Connection Found Between Saturn’s Aurora and Puzzling Radio Pulses
WASHINGTON —The ethereal ultraviolet glow, or aurora, that illuminates Saturn’s upper atmosphere near the planet’s poles is pulsing, recent observations show. What’s more, the glow waxes and wanes in conjunction with perplexing radio emissions that also emanate from the ringed planet. (more…)

IBM and University of Aberdeen Collaborate to Identify Molecules from the Deep Sea
— For the first time, atomic force microscopy helps scientists reveal the exact chemical structure of a natural compound
— Using this fast and accurate technique could open new possibilities in drug discovery and treatments
— Compound was extracted from a mud sample taken from the Mariana Trench, 10,916 meters (35,814 feet) below sea level
ABERDEEN, Scotland & ZURICH – 02 Aug 2010: In a pioneering research project, for the first time, scientists at IBM (NYSE: IBM) and the University of Aberdeen have collaborated to “see” the structure of a marine compound from the deepest place on the Earth using an atomic force microscope (AFM). The results of the project open up new possibilities in biological research which could lead to the faster development of new medicines in the future. (more…)
A Cellular Housekeeper, and Potential Target of Obesity Drugs, Caught in Action
Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have obtained the closest look yet of how a gargantuan molecular machine breaks down unwanted proteins in cells, a critical housekeeping chore that helps prevent diseases such as cancer. (more…)
