An
important chemical species, molecular oxygen is linear, has an
anisotropic shape, and spins from two unpaired electrons. However, until
now, we didn’t know how these properties influenced important oxidation
reactions. Researchers in Japan have now reported development of the
world's first molecular oxygen beam that can designate the alignment of
the molecular axis and spin direction.

A seaweed considered a threat to the healthy growth of coral reefs in Hawaii may possess the ability to produce substances that could one day treat human diseases, a new study led by scientists at Scripps Institution of Oceanography at University of California, San Diego has revealed.

Using
forensic-style chemical analysis, scientists in the U.K. and Germany
have directly linked seismic observations of the deadly 1980 Mount St.
Helens eruption to crystal growth within the magma chamber, the large
underground pool of liquid rock beneath the volcano. Building direct
links between observations at the surface and processes occurring
underground has been an ongoing problem for volcanologists.

Scientists
at the Georgia Institute of Technology recently achieved a 17% increase
in boiling efficiency by using an acoustic field to enhance heat
transfer. The acoustic field does this by efficiently removing vapor
bubbles from the heated surface and suppressing the formation of an
insulating vapor film.

Natural
pigments contain colorful molecules known as poryphyrins, which lend
vibrant colors through macrocyclic chemical structure that link several
small rings together in an “aromatic” framework. Sometimes, however,
synthesis causes the aromaticity to disappear. Researchers in Japan now
report a new way to manipulate the peculiar aromatic properties of
macrocycles.

Scientists from SLAC National Accelerator Laboratory, Stanford University, and Germany have figured out a key part of the industrial process for making methanol. It’s an important step toward improving the process—and eventually realizing the goal of turning a potent greenhouse gas, carbon dioxide, into fuel.

The scientific and technological literature is abuzz with nanotechnology
and its manufacturing and medical applications. But it is in an area
with a
less glitzy aura—plant sciences—where nanotechnology advancements are
contributing dramatically to agriculture. Researchers at Iowa
State University
have now demonstrated the ability to deliver proteins and DNA into plant
cells,
simultaneously.

Researchers
at the U.S. Air Force Research Laboratory have invented a simple,
inexpensive dip-and-dry treatment can convert ordinary silk into a
fabric that kills disease-causing bacteria—even the armor-coated spores
of microbes like anthrax—in minutes.

The current method of removing the greenhouse gas carbon dioxide from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So says Roger Aines, principal investigator for a team that has developed an entirely new catalyst for separating out and capturing carbon dioxide, one that mimics a naturally occurring catalyst operating in our lungs.

Electron
microscopes are often used to study fossils, which are first coated in
an ultra-thin layer of gold to help reveal details. However, removing
this layer often involves harsh chemicals like cyanide. Chemists in the
U.K. have developed a new method using ionic liquid to remove the
plating without destroying fossil features.
