Chronicle: Gold hybrid nanoparticles kill cancer
Dickson Kirui A transmission electron microscope image of a gold hybrid nanoparticle that could be used to treat cancer. The gold in the middle is surrounded by two pieces of iron oxide. Another weapon in the arsenal against cancer has been invented at Cornell: nanoparticles that identify, target and kill specific cancer cells while leaving healthy cells alone. Led by Carl Batt, the Liberty Hyde Bailey Professor of Food Science, the researchers synthesized nanoparticles -- shaped something like a dumbbell -- made of gold sandwiched between two pieces of iron oxide. To kill the cells, the researchers use a near-infrared laser, which is a wavelength that doesn't harm normal tissue at the levels used, but the radiation is absorbed by the gold in the nanoparticles. The research is reported in the Feb. 15 online edition of the journal Nanotechnology. "This is a so-called 'smart' therapy," Batt said. Gold has potential as a material key to fighting cancer in future smart therapies.
16 momentos históricos en los que las redes sociales sacaron lo mejor de nosotros
Internet sin duda ha transformado la manera de apoyar grandes causas. Durante años, las organizaciones no lucrativas y particulares han acudido a las redes sociales para difundir la necesidad de colaboración. Se podrían poner muchos ejemplos de la solidaridad mundial.

Energy Tower: Power for 15 Earths?
Researchers have designed a product that its inventors claim could easily produce between 15 and 20 times the total electricity the world uses today. Not only that, it could also be used as a desalination device and may be able to reverse the effects of global warming. Those are pretty big claims, but the researchers from the Technion - Israel Institute of Science seem confident that the "Energy Tower" could be a major solution to the world's problems. As project founder Professor Dan Zaslavsky explains, the Energy Tower works on the basic principle of convection: hot air rises and cold air falls. Any kind of water - from a sea or drainage ditch - would be added to the top of the tower. Because it relies on the sun for hot air, the Energy Tower is considered a type of solar power. Zaslavsky explains that the tower design could also be used for water desalination, producing fresh water at only half the cost of existing desalination technologies. Via: Israel21c
