Photosynthesis May Rely On Quantum Effect 234

forgethistory sends us to PhysOrg for a summary of new research suggesting that the near instantaneous energy transfer achieved by photosynthesis may rely on quantum effects. From the article: "Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency. Speed is the key — the transfer of the solar energy takes place almost instantaneously so little energy is wasted as heat. How photosynthesis achieves this near instantaneous energy transfer is a long-standing mystery that may have finally been solved."

Journal Journal: Kinkos has your number 2

CNN is carrying an article about a "new" (or rather, newly disclosed) way to get your personal information.

Now, experts are warning that photocopiers could be a culprit as well.

That's because most digital copiers manufactured in the past five years have disk drives -- the same kind of data-storage mechanism found in computers -- to reproduce documents.
