Scientists develop new technique for observing behavior of single molecules

(Phys.org) —Nearly every biological or chemical reaction that makes life possible involves single molecules interacting in the watery solution that sloshes in and around cells.

Exchange rate behaves like particles in a molecular fluid

The swings in market prices and exchange rates have the same foundations as molecule movements in physics. This has been demonstrated by a team of scientists from Switzerland and Japan.

Biomolecular tweezers facilitate study of mechanical force effects on cells and proteins

A new type of biomolecular tweezers could help researchers study how mechanical forces affect the biochemical activity of cells and proteins. The devices – too small to see without a microscope – use opposing magnetic and ...

Beating bacteria on Earth—and in space

By sheer strength of numbers, bacteria are by far the most successful life form on Earth. As we've learned over the past several decades of human spaceflight, they don't do too badly in microgravity either. For evidence, ...

Colloidal suspensions of microspheres in a liquid may not be simple systems

(Phys.org) —A colloidal suspension is a mixture in which microscopic particles of one substance are dispersed in another and because of its properties does not "settle" in the way that one might expect a stirred mixture of ...

Tipsy tottering, sunlight and the smell of coffee: It's all random

The warmth on your face, the scenic view outside – such delights are delivered to you by countless photons from the sun. But believe it or not, these photons move in much the same way as an inebriated person wandering home ...

Peering into the future: How cities grow

Migration patterns into and out of cities are the result of millions of individual decisions, which in turn are affected by thousands of factors like economics, location, politics, security, aesthetics, sentiments and others. ...

Researchers find boomerang shaped colloid does not conform to Brownian motion

(Phys.org) —A team of researchers working at Kent State University in Ohio has found that a custom shaped colloid that resembles a boomerang does not conform to Brownian motion, at least in the short term. In their paper ...

Tracking criminal movement using math: Will the next strike be near or far away?

One way to study criminal behavior and predict a criminal's next move is by analyzing his or her movement. Several mathematical models have addressed this in detail, in particular, the UCLA "burglary hotspot" model, also ...
