Latest Optical tweezers Stories
In a paradox typical of the quantum world, JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together.
There is considerable interest in understanding transport and information pathways in living cells.
Star Trek fans will remember "tractor beams," lasers that allowed the Starship Enterprise to trap and move objects, and now Tel Aviv University is turning this science fiction into science fact â€” on a nano scale.
While those wonderful light sabers in the Star Wars films remain the figment of George Lucasâ€™ fertile imagination, light mills â€“ rotary motors driven by light â€“ that can power objects thousands of times greater in size are now fact.
Scalable devices inspired by nature exhibit customizable optical properties suitable for applications ranging from highly sensitive sensors and detectors to invisibility cloaks.
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, physicist Mark Raizen and his group have done so.
Scientists are learning how our immune system senses and tracks down infection in the body by responding to chemical "scents" emitted by bacteria.
Scalable and reusable optical detection system boasts the sensitivity of a large microscope in a much smaller, cheaper package.
University of Michigan researchers have shown that tension on DNA molecules can affect gene expression---the process at the heart of biological function that tells a cell what to do.
With a bit of leverage, Cornell 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.
- a slit in a tire to drain away surface water and improve traction.
