Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity
11-30-2006 · EurekAlert!Last month, Roger Kornberg of Stanford University won the Nobel Prize in Chemistry for his efforts to unravel the molecular basis of eukaryotic transcription, in which enzymes give "voice" to DNA by copying it into the RNA molecules that serve as templates for protein in organisms from yeast to humans.

- Higher efficiency organic solar cell created by UCSB Nobel Laureate and research team
07-12-2007 · EurekAlert!
Using plastics to harvest the energy of the sun just got a significant boost in efficiency thanks to a discovery made at UC Santa Barbara. Nobel laureate and Alan Heeger, professor at UC Santa Barbara, worked with Kwanghee Lee of Korea and a team of scientists to create a new "tandem" organic solar cell with increased efficiency. The discovery, explained in the July 13 Science, marks a step forward in materials science.

Nearly 30 years after Nobel laureate Linus Pauling famously and controversially suggested that vitamin C supplements can prevent cancer, a team of Johns Hopkins scientists have shown that in mice, at least, vitamin C -- and potentially other antioxidants -- can indeed inhibit the growth of some tumors, just not in the manner suggested by years of investigation.

- Opening and closing the genome
02-22-2007 · EurekAlert!
A dynamic cast of gatekeeper enzymes controls access to the DNA for gene transcription, adding and removing particular molecules to open or close the genome as needed. Researchers have identified an important new player in this gene-control system, an enzyme responsible for removing certain molecules, or marks, involved in opening or closing chromatin, the material that makes up chromosomes. The activity of this enzyme is thought to be widespread, likely affecting many genes.
