Researchers create light from 'almost nothing' - 0 views

  •  
    (PhysOrg.com) -- A group of physicists working out of Chalmers University of Technology in Gothenburg, Sweden, have succeeded in proving what was until now, just theory; and that is, that visible photons could be produced from the virtual particles that have been thought to exist in a quantum vacuum. In a paper published on arXiv, the team describes how they used a specially created circuit called a superconducting quantum interference device (SQUID) to modulate a bit of wire length at a roughly five percent of the speed of light, to produce visible "sparks" from the nothingness of a vacuum.

Why some genes are silenced: Researchers find clue as to how notes are played on the 'g... - 0 views

    ScienceDaily (May 13, 2011) - Japanese and U.S. scientists in the young field of epigenetics have reported a rationale as to how specific genes are silenced and others are not. Because this effect can be reversed, it may be possible to devise therapies for cancer and other diseases using this information.

In a genetic research first, researchers turn zebrafish genes off and on - 0 views

  •  
    ScienceDaily (May 9, 2011) - Mayo Clinic researchers have designed a new tool for identifying protein function from genetic code. A team led by Stephen Ekker, Ph.D., succeeded in switching individual genes off and on in zebrafish, then observing embryonic and juvenile development. The study appears in the journal Nature Methods.

Researchers create self-assembling nanodevices that move and change shape on demand | K... - 0 views

  •  
    Harvard researchers have created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand.
    The nanodevice structure is based on the principle of tensegrity: its strength and stability results from the way it distributes and balances the counteracting forces of tension and compression.
    This new technology could lead to nanoscale medical devices and drug delivery systems, such as virus mimics that introduce drugs directly into diseased cells.
    Or it could one day be used to reprogram human stem cells to regenerate different kinds of injured organs and tissue.
