New tools reveal prelude to chaos

Picture a herd of sheep or cattle emerging from a shed or barn to graze a field. They head straight out of their digs to the pleasure of the pasture pretty much as one entity, but as the land opens up and the "grass gets ...

IBM scientists demo rocking Brownian motors for nanoparticles

Today, our IBM Research team published the first real world demonstration of a rocking Brownian motor for nanoparticles in the peer-review journal Science. The motors propel nanoscale particles along predefined racetracks ...

Tumble-proof cargo transporter in biological cells

ver wondered how a molecular nanomotor works when repairing DNA or transporting material such as organelles in the cell? Typically, nanomotors move along biopolymer filaments to go about their duties in the cell.  To do ...

The physics of salad dressing

Researchers at the University of Tokyo have shown that in phase separation in liquids, as is seen when oil and water separate, occurs as a result of the ordered motion of droplets. Initially, a great number of small droplets ...

Graphene mini-lab

A team of physicists from Europe and South Africa showed that electrons moving randomly in graphene can mimic the dynamics of particles such as cosmic rays, despite travelling at a fraction of their speed, in a paper about ...

Experiments illuminate how order arises in the cosmos

(Phys.org)—One of the unsolved mysteries of contemporary science is how highly organized structures can emerge from the random motion of particles. This applies to many situations ranging from astrophysical objects that ...
