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 ...
