Wings that Waggle could cut Aircraft Emissions By 20%
A research funded by the Engineering and Physical Sciences Research Council proposes a new
approach which dramatically reduce mid-flight drag, using tiny air powered jets which redirect the
air, making it flow sideways back and forth over the wing. The jets work by the Helmholtz
resonance principle - when air is forced into a cavity the pressure increases, which forces air out and
sucks it back , causing an oscillation the same phenomenon happens while blowing over a bottle.
The idea came from Weggling a piece of wing from side to side in a wind tunnel. The research is still
at concept stage. If successful this technology would also have a major impact on the aerodynamic
design and fuel consumptions of cars, boats and trains.

New Micro Honeycomb Materials reduce Aircraft Noise
Georgia Tech Research Institute (GTRI) research engineer Jason Nadler has developed a new micro
channeled material that reduces aircraft engine noise by wearing it down through a process called
viscous shear. Noise from commercial and military jet aircraft causes environmental problems for
communities near airports, obliging airplanes to follow often complex noise abatement loud. Structures
composed of many tiny tubes or channels can reduce more effectively than conventional methods.

Nanotechnology-Cleaning up our Water
Chemical engineers created nanoparticles out of gold and palladium to break down pollutants in groundwater. Dr. Michael Wong,
a chemical engineer at Rice University in Houston is trying to come up with a way to clean up polluted ground water. One of the
most common pollutants in United States groundwater is trichloroethylene (TCE), and Wong used nanoparticles (made out of
gold and palladium) ten thousand times smaller than a human hair and hydrogen to break TCE into something non-toxic. Dr.
Wong planed to test it at military sites first and then move onto industrial sites and dry cleaning businesses.

Autonomous Robot detects Shrapnel in Flesh
Bio Engineers at Duke University have developed a laboratory robot that can locate tiny pieces of
metal within flesh without the need of human assistance. The successful proof of feasibility
experiments lead the researchers to believe that in the future, such a robot could not only help to treat
shrapnel injuries on the battlefield, but might also be used for such medical procedures as placing and
removing radioactive "seeds" used in the treatment of prostate and other cancers. It could also be
useful in removing foreign,metallic objects from the eye.The researchers are encouraged that simple
and reasonably safe procedures will become routine in the near future.

Engineer designed more efficient, Quieter Bus
An engineer has designed an electric bus that runs on battery power. An automotive engineer Bruce Emmons created a 40 foot
battery powered electricity bus just like a giant golf cart. Inside the bus batteries and motor controllers drive electric motors in the
wheels. Instead of the bus being made from regular steel, everything is built of high-strength stainless steel (as
lightweight as aluminum) making the bus half the weight of a normal bus. Steel tubes also support the front
bumper and are designed to turn inside out in a crash to absorb energy and soften the blow. With no
transmission, drive shafts or other bulky mechanics taking up space, the floor can be low, making it easier to get
in and out and to provide a quieter and smoother ride. Emmon's next goal is to get it from the lab to buses all over
the city streets. Right now the bus is just a prototype. It has the potential to make different types of hybrid such
as a fuel cell or hydrogen bus.

Rejected Watermelons: The newest Renewable Energy Source
Watermelon juice can be a valuable source of biofuel. Researchers have shown that the juice of rejected watermelons can be
efficiently fermented into ethanol. Wayne Fish worked with a team of researchers at the South
Central Agricultural Research Laboratory in Lane, Oklahoma, US, to evaluate the biofuel
potential of juice from 'cull' watermelons-those not sold due to cosmetic imperfections, and
currently ploughed back into the field. About 20% of each annual watermelon crop is left in the
field because of surface blemishes. Researcher shown that the juice of these melons is a source of
readily fermentable sugars, representing a heretofore untapped feedstock for ethanol biofuel
production. Using the juice for ethanol production, either directly or as a diluent for other biofuel
crops, it can also be a source of lycopene and L-citrulline, the two 'nutraeuticals' for which
enough demand currently exists to make extraction economically worthwhile and still be
fermented into ethanol after removing these compounds from cull juice.

Step toward Quantum Computers
Raising prospects for building a practical quantum computer, physicists at the National Institute of
Standards and Technology (NIST) have demonstrated sustained, reliable information processing
operations on electrically charged atoms (ions) overcomes significant hurdles in scaling up ion-trapping
technology from small demonstrations to larger quantum processors potential to be different types of a
hybrid such as a fuel cell or hydrogen bus. Through its use of ions, the NIST researchers showcases a
promising architecture for a quantum computer, a potentially powerful machine that theoretically could
solve some problems that are currently intractable, such as breaking today's most widely used encryption
codes. Relying on the unusual rules of the submicroscopic quantum world, qubits can act as 0s and 1s
simultaneously, unlike ordinary digital bits, which hold only one value at any given time. Quantum computers also derive their
power from the fact that qubits can be "entangled," so their properties are linked, even at a distance. Ions are one of a number of
different types of quantum systems under investigation around the world for use as qubits in a quantum computer.
