Physicists simulate strongly correlated fermions Posted: 18 Mar 2012 11:39 AM PDT Combining known factors in a new way, physicists have solved an intractable 50-year-old problem: How to simulate strongly interacting quantum systems to accurately predict their properties. It could lead to superconductor applications and solving high-energy physics and ultra-cold atoms problems.

Surprise: Protons bypass hydrogen bonds but still change molecules Posted: 18 Mar 2012 11:39 AM PDT Common wisdom has it that protons only travel between molecules via hydrogen bonds: no hydrogen bonds, no proton transfer. Scientists investigating molecular components of RNA were surprised to find that protons can find ways to transfer even when hydrogen bonds are blocked. The discovery may open new opportunities for research in biology, environmental science, and green chemistry.
