Lawmakers face angry constituents in town hall meetings

NPR: "Many of the events this week appear to have been organized by conservative groups. A new Web site is called 'Operation Embarrass Your Congressman.' A widely circulated memo tells right-wing protesters how to treat their representative: 'Make him uneasy... stand up and shout out, and sit right back down... rattle him.'" The man who wrote the memo belongs to the conservative group Tea Party Patriots.

Tips to avoid heat stroke

The first sign of dangerous heat stroke can be just that – no sweat. As the temperature rises, your body’s natural cooling mechanism, sweat (or more kindly, perspiration), evaporates and helps to cool your body. But on those hot, humid cut-the-air-with-a knife days, evaporation is slowed and your body may not be able to keep itself cool.

Walk, don't drive! community promotion of physical activity has two-fold benefit

About half of the car trips in the U.S. are less than five miles - a distance easily navigated by walking or cycling. Reducing short-distance car trips has many benefits - it decreases car accidents, has positive benefits for the environment and increases physical health and activity, says communication professor Edward Maibach of George Mason University. An expert in climate change communication research, Maibach says that community leaders should make promotion of physical activity a priority.

Lasers and nanotubes offer potential future cancer treatments

By injecting man-made, microscopic tubes into tumors and heating them with a quick, 30-second zap of a laser, scientists have discovered a way to effectively kill kidney tumors in nearly 80 percent of mice. Researchers say that the finding suggests a potential future cancer treatment for humans.

Heat shock proteins provide protection against cataracts

The human eye lens consists of a highly concentrated mix of several proteins. Protective proteins prevent these proteins from aggregating and clumping. If this protective function fails, the lens blurs and the patient develops cataracts. Two research groups at the Department of Chemistry of the Technische Universitaet Muenchen (TUM) have succeeded in explaining the molecular architecture of this kind of protective protein.

Scientists combine two nanoparticles into one tiny package

Nanoparticles are being developed to perform a wide range of medical uses - imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package.

Researchers decipher special role of the messenger Beta-interferon for immune responses

Researchers from the Molecular Immunology group at the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany have now shown that Beta-Interferon also plays a crucial role during an immune response: without Beta-Interferon immune cells are unable to show "wanted posters" of pathogens to other cells.

"Drops" of gold that burn tumors

At a technical breakfast, Romain Quidant presented his research into the detection and treatment of cancer using gold nanoparticles illuminated with laser light. Quidant, who was recently awarded the Fresnel Prize 2009 that recognizes the highest level of excellence amongst emerging researchers in the field of photonics, is an ICREA researcher at the UPC's Institute of Photonic Sciences (ICFO) and a fellow of the Cellex Foundation Barcelona.

Overcoming the big ‘nanotech’ challenges

Whether in the fields of medicine, sustainable energy supply or environmental protection, without making use of nanotechnology we will not be capable of overcoming the challenges which the future presents. In parallel with these efforts, though, it is essential that we examine the new technology very carefully for potential risks, such as those presented by free nanoparticles.

TV ad wars beginning over health overhaul proposals

The Associated Press reports that ads focused on congressional efforts to overhaul the nation's system are now appearing and will heat up as the summer progresses. "Through June 27, $31 million has been spent for roughly 47,000 TV ads on health care this year, says Evan Tracey, president of the Campaign Media Analysis Group, a firm that tracks issue advertising. That's double the roughly $14 million the insurance industry spent in 1993 and 1994 for the famous 'Harry and Louise' ads..., but a fraction of the $250 million Tracey guesses will ultimately be spent this year."
