A
group of scientists took to the skies in a slow-moving airship Thursday
in search of meteorites that rained over California's gold country last
month. It's the latest hunt for extraterrestrial fragments from the
April 22 explosion that was witnessed over a swath of Northern
California and Nevada.

More
than 600,000 bridges in the U.S are 20 feet long or longer. Some are
over a century old and many of them national monuments. Three government
organizations, including the U.S. Army Corp of Engineers, have joined
forces to conduct a unique series of tests on bridge scheduled to be
demolished. From this, they hope to assess the vulnerability of critical
structural components of existing steel bridges.

A
group of high-tech tycoons wants to mine nearby asteroids wants to use
commercially built robotic ships to squeeze rocket fuel and valuable
minerals like platinum and gold out of the lifeless rocks that routinely
whiz by Earth. The inaugural step, to be achieved in the next 18 to 24
months, would be launching the first in a series of private telescopes
that would search for rich asteroid targets.

A Sandia National Laboratories modeling study contradicts a long-held belief of geologists that pore sizes and chemical compositions are uniform throughout a given strata, which are horizontal slices of sedimentary rock. By understanding the variety of pore sizes and spatial patterns in strata, geologists can help achieve more production from underground oil reservoirs and water aquifers.

New research from North
Carolina State University shows that a wind-driven "tumbleweed" Mars
rover would be capable of moving across rocky Martian terrain—findings
that could also help the National Aeronautics and Space Administration
(NASA)
design the best possible vehicle.

A new collaboration between Oxford University
and the Lausanne Museum of Zoology will use the latest genetic
techniques to
investigate organic remains that some have claimed belong to the 'Yeti'
and
other 'lost' hominid species.

Ion bombardment of metal surfaces is an important, but poorly understood, nanomanufacturing technique. New research using sophisticated supercomputer simulations has shown what goes on in trillionths of a second. The advance could lead to better ways to predict the phenomenon and more uses of the technique to make new nanoscale products.

A research group from Stony Brook University reports the development and demonstration of a novel probe for atomic quantum matter. Their work describes a proof-of-principle experiment on the diffraction of atomic de Broglie waves from a strongly correlated gas of atoms held in an optical lattice.

A new study by civil engineers at Massachusetts Institute of Technology shows that using stiffer pavements on the nation's roads could reduce vehicle fuel consumption by as much as 3%—a savings that could add up to 273 million barrels of crude oil per year, or $15.6 billion at today's oil prices. This would result in an accompanying annual decrease in carbon dioxide emissions of 46.5 million metric tons.

Plans
to create the world's first carbon-neutral higher-speed locomotive were
unveiled this week by the Coalition for Sustainable Rail, which has the goal
of proving the viability of solid biofuel—torrefied biomass—and modern
steam locomotive technology. The first step in those plans is to break
the world speed record for steam trains.

A
team of engineers at the University of California, Berkeley have
developed a way to keep tabs on pipeline health by using a magnetic
resonance imaging machine similar to the ones used in hospitals. Their
technology is called the Magnetic Response Imaging System (MRIS), and it
will be able to look at the state of underground pipelines.

The
first global analysis of carbon stored in seagrasses has revealed a
surprising figure. While a typical terrestrial forest stores about
30,000 metric tons of carbon per square kilometer, most of which is in
the form of wood, coastal seagrasses can account for 83,000 metric tons
of carbon per square kilometer. Their global impact is significant as
well.

Biomedical engineers at University of California, Davis have
developed a microfluidic chip to test for latent tuberculosis. They hope
the
test will be cheaper, faster, and more reliable than current testing for
the
disease.
