Scientists Develop Transparent Solar Concentrator

The newly developed transparent luminescent solar concentrator can be used on buildings, cell phones and any other device that has a clear surface, says a group of scientists led by Dr Richard Lunt of Michigan State University.

Research in the production of energy from solar cells placed around luminescent materials is not new.
Past efforts, however, have yielded poor results – the energy production was inefficient and the materials were highly colored.
Now Dr Lunt and his colleagues at Michigan State University have developed transparent luminescent materials that use small organic molecules to absorb specific non-visible wavelengths of sunlight.
“We can tune these materials to pick up just the UV… Read more

Retooling for Human Gene Therapy: New and Improved Adenoviral Vectors

Dr Juliana Small of the University of Pennsylvania, Drs Raj Kurupati, Xianqyang Zhou and their colleagues from the Wistar Institute have developed a novel adenoviral vector for delivery of multiple transgenes.

With the genetic basis of a number of human diseases known, many attempts have been made to treat the disorders by adding back the correct genetic information to individual cells. Adding foreign genetic material to treat disorders comes under the realm of gene therapy.
