Understanding tiny droplets can make for better weather forecasts

When you see how difficult it is to get even next week's weather forecast right, you can imagine the challenges researchers are faced with when it comes to predicting the weather decades from now.

New data analysis technique distinguishes active from passive fluctuations inside cells

Inside every living cell, internal structures are continuously moving about. Under a microscope, organelles such as the nucleus, mitochondria, transport vesicles, or even external flagella wobble and twitch. This may happen ...

Solving the problem of sea ice thickness distribution using molecular concepts

Yale University scientists have answered a 40-year-old question about Arctic ice thickness by treating the ice floes of the frozen seas like colliding molecules in a fluid or gas.

Protein machines make fluctuating flows unconsciously

An international research group has demonstrated that protein machines, regardless of their specific functions, can collectively induce fluctuating hydrodynamic flows and substantially enhance the diffusive motions of particles ...

What happens when Newton's third law is broken?

Even if you don't know it by name, everyone is familiar with Newton's third law, which states that for every action, there is an equal and opposite reaction. This idea can be seen in many everyday situations, such as when ...

Researchers develop computer model of bacterial colony interactions

(Phys.org)—One of the remarkable properties of bacterial colonies is the self-ordering aggregation and orientation of bacterial cells. Bacteria secrete extracellular polymeric substances (EPS) that form biofilm-like structures ...

How the physics of champagne bubbles may help address the world's future energy needs

Uncork a bottle of champagne, and as the pressure of the liquid is abruptly removed, bubbles immediately form and then rapidly begin the process of "coarsening," in which larger bubbles grow at the expense of smaller ones.

Scientists film magnetic memory in super slow-motion

Researchers at DESY have used high-speed photography to film one of the candidates for the magnetic data storage devices of the future in action. The film was taken using an X-ray microscope and shows magnetic vortices being ...

Study explains how Maxwell's demon uses mutual information to extract work

(Phys.org) —Maxwell's demon, the hypothetical doorman that controls how particles travel between two chambers in an attempt to decrease entropy, is at its heart a feedback-controlled system. The demon makes measurements on ...

Model system used to illustrate phase transition of a mixture of active and passive particles

Systems containing self-propelling particles, such as bacteria or artificial colloidal particles, are always out of equilibrium but may show interesting transitions between different states, reminiscent of phase transitions ...
