Gizmorama!

Good Morning,

Today, I have fascinating stories about alternative energy
in the form of wind energy, new developments in gene
therapy, and a new fuel alternative created from algae.

Science is all around us. You can’t help learn something
new everyday.

Until Tomorrow,

——– New wind turbine blade technology created ———

WEST LAFAYETTE, Ind. - Purdue University and Sandia
National Laboratory scientists say they’ve developed a
technology designed to improve the efficiency of wind
turbine blades. The researchers said the technology uses
sensors and computational software to constantly monitor
forces exerted on wind turbine blades. “The ultimate goal
is to feed information from sensors into an active control
system that precisely adjusts components to optimize
efficiency,” said Purdue doctoral student Jonathan White,
who is leading the research with Professor Douglas Adams.
They said their system also could help improve wind turbine
reliability by providing critical real-time information to
the control system to prevent catastrophic wind turbine
damage from high winds. “Wind energy is playing an increas-
ing role in providing electrical power,” Adams said. “The
United States is now the largest harvester of wind energy
in the world. The question is, what can be done to wind
turbines to make them more efficient, more cost-effective
and more reliable?” The scientists said the sensors could
be instrumental in future turbine blades that have “control
surfaces” and simple flaps, such as those on an airplane’s
wings, to change the aerodynamic characteristics of the
blades for better control. Because the flaps would be
changed in real time to respond to changing winds, constant
sensor data would be critical. The study was detailed in a
paper presented this week in Chicago during the Windpower
2009 Conference and Exhibition.

——— New method of gene therapy is developed ———-

FLANDERS, Belgium - Flemish scientists say they have
developed an improved and safer technique to deliver genes
into the body’s cells during genetic therapy. Gene therapy
is the introduction of genetic material into a patient’s
cells resulting in a cure or a therapeutic effect, said
researchers at the Flanders Institute for Biotechnology
in Belgium. The success of gene therapy ultimately depends
on the gene delivery vehicles, or vectors, and most
vectors have been derived from viruses that can be tailor-
made to deliver therapeutic genes. The drawback is some
of the viral vectors can induce side effects, including
cancer and inflammation. Now Marinee Chuah, Thierry
VandenDriessche, Eyayu Belay and colleagues at the
Catholic University of Leuven say they’ve developed a non-
viral approach that overcomes some limitations associated
with viral vectors. The technique is based on non-viral
genetic elements called transposons — mobile DNA elements
– that the scientists constructed to carry therapeutic
genes into the target cell DNA, eliminating the need for
viral vectors. “We show for the first time that it is now
possible to efficiently deliver genes into stem cells,
particularly those of the immune system, using non-viral
gene delivery,” Chuah said. The researchers, in collabor-
ation with Zsuzsanna Iszvak and Zoltan Ivics and
colleagues at the Max Delbrück Center in Berlin are now
testing the technology to treat specific diseases,
including cancer and genetic disorders.

——— Long Island Sound scum may be biofuel ———–

NEW HAVEN, Conn. - Connecticut scientists have focused on
algae from Long Island Sound in their quest for native
environmentally friendly biofuels. The Hartford Courant
reported Tuesday researchers at the University of New
Haven have joined universities and private enterprises
in the nationwide race to find cost-effective biofuel
sources. “We’re trying to find the Connecticut feedstock,”
said Carmella Cuomo, the university’s associate professor
heading the team of algae researchers. The university
hopes by cultivating algae gleaned from the water it can
lessen the dependence on corn and soy products. Those
crops use too much traditional fuel to transport raw
products to biofuel processing factories. The first
generation of biofuels was unsustainable,” said Richard
Parnas, the University of Connecticut’s chemical engineer-
ing director and head of the university’s biofuels program.
Unsustainability prompted research in alternative fuel
sources, such as algae. Algae-based biodiesel companies
raised $195 million in investments last year, Cleantech
Group, a data-gathering company for the industry, reported.
Research investment in second-generation biofuels increased
last year to $600 million, up from $139 million in 2007.
