Solar cell directly splits water for hydrogen
Plants trees and algae do it. Even some bacteria and moss do it, but scientists have had a difficult time developing methods to turn sunlight into useful fuel. Now, Penn State researchers have a proof-of-concept device that can split water and produce recoverable hydrogen.

Since 2004 the U.S. Food and Drug Administration has approved three new-generation anticancer therapies that target epidermal growth factor receptor (EGFR), a protein that is greatly overexpressed on certain types of tumors, including some forms of colorectal and lung cancer. For patients with EGFR-positive tumors, these drugs can be lifesavers, but at present, there is no good way to predict who will respond to anti-EGFR therapy. That may change, though, thanks to the development of two quantum dot-based systems that can image EGFR expression in living animals.

Read moreTargeted dendrimer advances in preclinical studies
Although a variety of nanoparticles continue to show promise for improving cancer imaging and therapy, regulators and drug developers are concerned that these delivery systems may prove difficult to manufacture on a consistent basis, which is key for any agent designed for use in humans. A new study provides data showing that such concerns can be overcome.

Brain cancer is one of the most aggressive and lethal of malignancies, made even more difficult to treat by the fact that most anticancer drugs have a hard time even getting to the tumors. Now, studies by three different groups of researchers show that targeted nanoparticles hold promise for solving this delivery problem.

Carbon nanotubes have shown real promise as highly accurate vehicles for delivering antitumor agents into malignant cells, but a dearth of data about what happens to the tubes after they discharge their medical payloads has been a major stumbling block to progress. Now, two studies at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response have revealed some reassuring answers after months of tracking the tiny tubes inside mice.
