(1) MIT: New insights on fusion power

David Chandler, MIT News Office
December 3, 2008

Research carried out at MIT's Alcator C-Mod fusion reactor may have brought the promise of fusion as a future power source a bit closer to reality, though scientists caution that a practical fusion powerplant is still decades away.

(2)Disappearing superconductivity reappears -- in 2-D

Scientists studying a material that appeared to lose its ability to carry current with no resistance say new measurements reveal that the material is indeed a superconductor -- but only in two dimensions. Equally surprising, this new form of 2-D superconductivity emerges at a higher temperature than ordinary 3-D superconductivity in other compositions of the same material.

"BioPath is a database of biochemical pathways that provides access to metabolic transformations and cellular regulations derived from the Roche Applied Science "Biochemical Pathways" wall chart.

BioPath contains a library of cross-linked biochemical molecules and reactions. All structure and reaction information is stored on an atomic level allowing the direct access to all atoms and bonds of all metabolites and to the bonds broken and made during an enzymatic reaction.

BioPath is designed to support scientists to understand the impact of gene regulations on biological systems for drug target identification and provides the following features:

  • 1,175 molecules with connection tables including stereochemical information
  • 1,545 biochemical reactions stoichiometrically balanced, with marked reaction centers and atom-atom mapping numbers between educts and products
  • 1,000 unique enzymes represented by names and EC numbers
  • 202 pathways represented by names
  • Covered organism: prokaryotes, plants, yeasts and animals, general pathways
  • Subcellular localization of pathways (cytosol, chloroplasts, mitochondria, ...)"[1]
