Tiny 'LEGO brick' -style studs make solar panels a quarter more efficient Posted: 18 Oct 2013 05:44 AM PDT Most solar cells are made using thick layers of material to absorb sunlight, but have been limited in the past by relatively high costs. Many new, lower cost designs are limited as their layer of light-absorbing material is too thin to extract enough energy. In new research, scientists have demonstrated that the efficiency of all solar panel designs could be improved by up to 22 per cent by covering their surface with aluminium studs that bend and trap light inside the absorbing layer.

Web-based map allows users to see intricate patterns in U.S. Population Posted: 17 Oct 2013 11:44 AM PDT A new web-based mapping site allows users to see stark racial boundaries, subtle shifts in income, and intricate patterns of race, age, household size and income for any location in the United States

3D images from PET/CT scans help surgeons envision tumors Posted: 17 Oct 2013 08:11 AM PDT A hologram-like display of a patient's organs based on molecular PET/CT images helps surgeons plan surgery by allowing them to see detailed anatomical structure, peel away layers of tissue, and see all sides of a tumor, before entering the operating room to excise it.

Watching the heartbeat of molecules Posted: 17 Oct 2013 05:01 AM PDT A team of scientists now report on a new method of rapidly identifying different molecular species under a microscope. Their technique of coherent Raman spectro-imaging with two laser frequency combs takes a big step towards the holy grail of real-time label-free biomolecular imaging.
