A
research team led by investigators at Mayo Clinic in Florida has found
that a small device worn on a patient's brow can be useful in monitoring
blood oxygen in stroke patients in the hospital. Unlike a pulse
oximeter, which also performs this task, the head patch uses
near-infrared spectroscopy to quickly the presence of another stroke.

Tons
and tons of old produce goes to waste each year, much of it simply
thrown away. A new biogas plant near Stuttgart, in Germany, has been
built specifically to convert this market waste into methane for
commercial use

While
researchers have long known of the incredible strength of spider silk,
the robust nature of the tiny filaments cannot alone explain how webs
survive multiple tears and winds that exceed hurricane strength. A
combination of computer simulations and new experimental observations
have revealed more about the sacrificial beams and stress-dependent
materials that make silk so strong.

Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nm in wavelength. In reaching the new band of the spectrum, the JILA experiments demonstrated for the first time a very fine mini-comb-like structure within each subunit, or harmonic, of the larger comb, drastically sharpening the measurement tool.

Lawrence Berkeley National Laboratory researchers have developed a relatively fast, easy, and inexpensive technique for inducing nanorods to self-assemble into aligned and ordered macroscopic structures. This technique should enable more effective use of nanorods in solar cells, magnetic storage devices, and sensors, and boost the electrical and mechanical properties of nanorod-polymer composites.

Using some of the most powerful nuclear magnetic resonance
equipment available, researchers at the University
of California, Davis, are making discoveries about the shape
and structure of biological molecules—potentially leading to new ways to
treat
or prevent diseases such as breast cancer and Alzheimer’s disease.

Graphene has been touted as the next silicon, with one major problem—it is too conductive to be used in computer chips. Now, scientists from the University of Manchester have given its prospects a new lifeline. The Manchester team has literally opened a third dimension in graphene research.

Mars may have been arid for more than 600 million years, making it too hostile for any life to survive on the planet’s surface, according to researchers who have been carrying out the painstaking task of analyzing individual particles of Martian soil. The researchers have spent three years analyzing data on Martian soil that was collected during the 2008 NASA Phoenix mission to Mars.

In chemistry, downsizing can have positive attributes. Reducing the number of steps and reagents in synthetic reactions, for example, enables chemists to boost their productivity while reducing their environmental footprint. This type of ‘atom economy’ could soon improve, thanks to a new rare-earth metal catalyst developed at the RIKEN Advanced Science Institute, Wako.

Sometimes,
DNA extracted from a plant’s green chloroplasts show great similarities
with related species that grow in the same area. The phenomenon has
confounded scientists, who have assumed the sexually incompatible
species somehow cross-bred. Now, researchers say they have the answer,
and that cross-breeding isn’t even necessary for this “chloroplast
capture” to occur.

Researchers
in the U.S. have invented a process that reattaches severed nerves in
just minutes, resorting limb use in days or week. The method is similar
to the cellular mechanism used by many invertebrates to repair damage to
nerve axons.

As the United States transitions away from a primarily petroleum-based transportation industry, a number of different alternative fuel sources—ethanol, biodiesel, electricity, and hydrogen—have each shown their own promise. Hoping to expand the pool even further, researchers at Argonne National Laboratory have begun to investigate adding one more contender to the list of possible energy sources for light-duty cars and trucks: Compressed natural gas.

Data
from Scripps Institution of Oceanography, NOAA, and the University of
California, San Diego has been used by Google experts this week to
sharpen the resolution of seafloor maps in the popular Google Earth
application. The original version of the program, according to a Scripps
geophysicist, had high resolution but was full of thousands of blunders
from old data.

A
camera aboard one of NASA's twin Gravity Recovery And Interior
Laboratory (GRAIL) lunar spacecraft has returned its first unique view
of the far side of the moon. Thousands of fourth- to eighth-grade
students will select target areas on the lunar surface and send requests
to the GRAIL MoonKAM Mission Operations Center in San Diego. Photos of
the target areas will be sent back by the satellites for students to
study.

A
team of Massachusetts Institute of Technology researchers has
developed a
way of making a high-temperature version of a kind of materials called
photonic
crystals, using metals such as tungsten or tantalum. The new
materials—which
can operate at temperatures up to 1,200 C—could find a wide variety of
applications powering portable electronic devices, spacecraft to probe
deep
space, and new infrared light emitters that could be used as chemical
detectors
and sensors.
