Good Morning,
Happy Earth Day! Earth Day is intended to inspire awareness of
and appreciation for the Earth's environment. Here is a link
to more on its history and how it all got started.

Twin space probe design phase begins
The U.S. space agency said design work has started on its
radiation storm probes -- twin spacecraft that will be
launched into the Earth's radiation belts. Researchers said
the National Aeronautics and Space Administration spacecraft
are being designed to provide insight into the physical
dynamics of near-Earth space, where violent space weather
can affect astronauts, satellites and even ground-based
technologies. Researchers and engineers at the Johns Hopkins
University Applied Physics Laboratory in Laurel, Md., will
build and operate the twin probes, which are scheduled for a
2011 launch and a primary mission of two years. The radiation
belts are two doughnut-shaped regions encircling Earth, where
high-energy particles are trapped by the planet's magnetic
field, scientists said. Most Earth-orbiting spacecraft pass
through the belts, which can affect both astronauts and
spacecraft. Scientists hope the space mission will resolve
decades-old scientific mysteries of how such particles become
energized to such high levels and how the radiation belts vary
so dramatically with changing conditions on the sun. The
instruments will be provided by teams managed by Boston
University, the University of Iowa, the University of
Minnesota, the New Jersey Institute of Technology and the
National Reconnaissance Office.

NASA tech might be used for Web gaming
The U.S. space agency says educators soon might soon be able
to use computer-simulation games that employ space age
technologies. The National Aeronautics and Space Administration
sponsored a Monday workshop to present its concept of delivering
NASA content through a Massively Multi-player Online, or MMO,
educational game to interested development partners. Designed
to enhance learning in science, technology, engineering and
mathematics, or STEM, the game would be designed to draw
players into a synthetic environment that can serve as a
powerful "hands-on" tool for teaching a range of complex
subjects, officials said. "NASA will continue to pursue
innovative strategies to encourage students to improve their
interest and performance in STEM and related careers," said
Joyce Winterton, NASA's assistant administrator for education.
"The use of online educational games can capture student
interest in NASA's missions and science." The space agency
said it expects the game to appeal mainly to teenagers and
college students.

Synthetic gene therapy material is created
U.S. cardiology researchers report creating a versatile
synthetic material that can bind to a variety of gene therapy
vectors. The Children's Hospital of Philadelphia scientists
said their delivery technology can be custom designed for
controlled local release of therapeutic genes at a disease site.
The researchers used their new synthetic formulation to bind
adenoviruses to bare metal stents placed in the carotid arteries
of research rats. Adenoviruses served as a gene therapy vector
to carry genes for an enzyme that significantly reduced
restenosis -- the hazardous narrowing of a blood vessel that
often occurs despite the presence of a stent designed to hold
it open. The eventual goal is to use the technique to treat
human artery disease. "We developed a synthetic gene delivery
system that can be used for any gene therapy vector, not just
adenoviruses," said study leader Dr. Robert Levy. "Furthermore,
this new formulation allows us to increase the dosage of gene
therapy vectors delivered, and we can tune the materials for
sustained release over a longer time period." The study is
reported in the online edition of the journal Circulation.
