Scientists identified a mechanism for the formation of soot involving a series rapid chemical reactions rather than the typical condensation of particles from gas. The results are critical to developing methods for controlling emissions responsible for millions of deaths annually, severe degradation of air quality, and enhanced global warming. Read more »
Expanding the Infrared Nanospectroscopy Window
An innovative infrared-light probe with nanoscale spatial resolution has been expanded to cover previously inaccessible far-infrared wavelengths. The ability to investigate heterogeneous materials at nanometer scales and far-infrared energies will benefit a wide range of fields, from condensed matter physics to biology. Read more »
Targeting Bacteria That Cause Meningitis and Sepsis
Researchers determined the structure of a human antibody that broadly protects against a bacterium that causes meningitis and sepsis. The work provides molecular-level information about how the antibody confers broad immunity against a variable target and suggests strategies for further improvement of available vaccines.

Clues to the Solar System’s Original “Bricks and Mortar”
In comet dust, researchers discovered composite organic-inorganic mineral grains that are likely to be the original “bricks and mortar” of the solar system. “Forensic” samples preserved from the birth of the solar system allow investigations into the nature of the atomic and molecular ancestry of the terrestrial planets and life on Earth.
