Secrets of the first practical artificial leaf
May 11, 2012 – 8:00 pm
Secrets of the first practical artificial leaf - Researchers report development of the first practical artificial leaf -- a milestone in the drive for sustainable energy that mimics the process, photosynthesis, that green plants use to convert water and sunlight into energy. The article notes that unlike earlier devices, which used costly ingredients, the new device is made from inexpensive materials and employs low-cost engineering and manufacturing processes.

Decapping of Long Noncoding RNAs Regulates Inducible Genes
May 11, 2012 – 6:00 am
Decapping of Long Noncoding RNAs Regulates Inducible Genes - Decapping represents a critical control point in regulating expression of protein coding genes. Genes that react to cellular sugar content are regulated by a long non-coding RNA via an unexpected mechanism. Researchers demonstrate that decapping also modulates expression of long noncoding RNAs (lncRNAs). Reference: S.
