Scientists build working model of life's engine

(PhysOrg.com) -- Researchers at the University of Southern California have built a theoretical working model of the cellular engine that powers all life.

Virus uses 'Swiss Army knife' protein to cause infection

In an advance in understanding Mother Nature's copy machines, motors, assembly lines and other biological nano-machines, scientists are describing how a multipurpose protein on the tail of a virus bores into bacteria like ...

New molecular robot can be programmed to follow instructions

Scientists have developed a programmable "molecular robot" -- a sub-microscopic molecular machine made of synthetic DNA that moves between track locations separated by 6nm. The robot, a short strand of DNA, follows instructions ...

New tool for cell research may help unravel secrets of disease

Advancements in understanding rotational motion in living cells may help researchers shed light on the causes of deadly diseases, such as Alzheimer's, according to Ning Fang, an associate scientist at the U.S. Department ...

A fantastic voyage brought to life

Ever since the 1966 Hollywood movie, doctors have imagined a real-life Fantastic Voyage -- a medical vehicle shrunk small enough to "submarine" in and fix faulty cells in the body. Thanks to new research by Tel Aviv University ...

Molecular motors: Power much less than expected?

An innovative measurement method was used at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw for estimating power generated by motors of single molecule in size, comprising a few dozens of ...

Raising the prospects for quantum levitation

More than half-a-century ago, the Dutch theoretical physicist Hendrik Casimir calculated that two mirrors placed facing each other in a vacuum would attract. The mysterious force arises from the energy of virtual particles ...
