Chemical engineers at the Massachusetts Institute of Technology have designed a new type of drug-delivery nanoparticle that exploits a trait shared by almost all tumors: They are more acidic than healthy tissues. Such particles could target nearly any type of tumor, and can be designed to carry virtually any type [...]
Researchers at the University of California, Los Angeles (UCLA) have discovered a way to “wake up” the immune system to fight cancer by delivering an immune system–stimulating protein in a nanoscale container called a vault directly into lung cancer tumors. The new method harnesses the body’s natural defenses to fight [...]
Supermoon or perigee-syzygy on 19th March 2011 was the largest super moon in nearly 20 years. The celestial event brings no danger to Earth. On Twitter, Facebook and Flickr, skywatchers around the world posted pictures and reactions to the the biggest full moon in nearly decades. During the so-called "supermoon," the moon wasn't just at its closest approach to Earth in its elliptical orbit, it was closer than it has been in 18 years.
Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a new study suggests. This change might take a toll on public health.
Here on Earth we worry about our planet’s atmosphere warming by a few degrees on average over the next century, and even weather fronts bring temporary changes in temperature of no more than tens of degrees. Now astronomers writing in the January 29 Nature report on an extra-solar planetary system [...]
