Tractor beam is ‘science fiction made real’
NYU (US) — A tractor beam can pull microscopic particles and has a range of potential uses, from microfluidics to far-out tasks like grabbing dust from comet tails. Continue…

Nano-origami: RNA folding in real time
STANFORD (US) — Optical tweezers and sub-nanoscale precision have allowed biophysicists to follow the process—and the consequences—of RNA folding in real time. (more…)

Stretch a gene to silence it
U. ARIZONA (US) — Cells may control genes by simply stretching them, a discovery that could pave the way for applications that require precise control over gene expression, such as the “lab on a chip.” (more…)

Physicists prove Einstein wrong
U. TEXAS-AUSTIN (US)—A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicists have done just that. (more…)

Tiny light beam budges nanoscale object
CORNELL (US)—With a bit of leverage, researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That’s enough to completely switch the optical properties of the structure from opaque to transparent, they report. (more…)

Tiny tweezers snag living cells
PENN STATE (US)—Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now researchers have developed a system that uses sound as a tiny tweezer small enough to be placed on a chip. (more…)
