'The photon force is with us': Harnessing light to drive nanomachines from PhysOrg.com
Science fiction writers have long envisioned sailing a spacecraft by the optical force of the sun's light. But, the forces of sunlight are too weak to fill even the oversized sails that have been tried. Now a team led by researchers at the Yale School of Engineering & Applied Science has shown that the force of light indeed can be harnessed to drive machines — when the process is scaled to nano-proportions.

Researchers identify a potentially universal mechanism of aging
Researchers identify a potentially universal mechanism of aging from PhysOrg.com
Like our current financial crisis, the aging process might also be a product excessive deregulation. Researchers have discovered that DNA damage decreases a cell's ability to regulate which genes are turned on and off in particular settings. This mechanism, which applies both to fungus and to us, might represent a universal culprit for aging.

How Time-Traveling Could Affect Quantum Computing
How Time-Traveling Could Affect Quantum Computing from PhysOrg.com
(PhysOrg.com) -- If space-time were constructed in such a way that you could travel back in time, it would create some pretty strange effects. One of these oddities, as many people know, is the “grandfather paradox.” Here, a person travels back in time to kill their grandfather before the person’s father is born, thus preventing their own birth.

New laser method reproduces art masterworks to protein patterns
New laser method reproduces art masterworks to protein patterns from PhysOrg.com
Canadian researchers have created a new protein patterning technique that's enabled them to reproduce complex cellular environments and a miniature version of a masterpiece painting. According to a new study published in the journal Lab on a Chip, scientists from Université de Montréal, the Maisonneuve-Rosemont Hospital Research Centre, McGill University and the Montreal Neurological Institute have developed a laser technology that can mimic the protein patterns that surround cells in vivo and that could lead to great advances in neuroscience.

U.S. military researchers grow new limbs, organs
American military researchers say they have unlocked the secret to regrowing limbs and recreating organs in humans who have sustained major injuries.
Using "nanoscaffolding," the researchers have regrown a man's fingertip and the internal organs of several test subjects.
