Quantum Coherent-Like State Observed in a Biological Protein for the First Time
American Institute of Physics (AIP)

If you take certain atoms and make them almost as cold as they possibly can be, the atoms will fuse into a collective low-energy quantum state called a Bose-Einstein condensate. In 1968 physicist Herbert Fröhlich predicted that a similar process at a much higher temperature could concentrate all of the vibrational energy in a biological protein into its lowest-frequency vibrational mode. Now scientists in Sweden and Germany have the first experimental evidence of such so-called Fröhlich condensation. They report their results in the journal Structural Dynamics.

The Savory Secrets of Baked Bread
American Institute of Physics (AIP)

For all our love of the simple slice of bread, we don’t have a solid understanding of much of the science behind squishy dough, like the interplay between a dough's microstructure and its rheology -- the way in which it deforms and flows. Understanding this science would help bakers improve bread recipes intended for ovens both big and small. Next month, during The Society of Rheology's 87th Annual Meeting, a team of researchers from Belgium and the Netherlands will describe how gluten and starch affect the overall dough behavior, as well as the optimal amount of glucose oxidase enzyme to use to enhance bread-making performance.

New Surfaces Delay Ice Formation
American Institute of Physics (AIP)

"People intuitively know that frost can be bad," said Amy Betz, a professor in mechanical engineering at Kansas State University. Betz and her colleagues have created a surface that can significantly delay frost formation, even at temperatures of down to 6 degrees Celsius below freezing. The surface is biphilic, meaning it repels water in some areas and attracts it in others. The researchers describe their results in a paper in the journal Applied Physics Letters.

Double the (Quantum) Fun
American Institute of Physics (AIP)

A group of researchers in Japan is exploring the behavior of a certain type of SET (single-electron transistor) made from two quantum dots, which are bits of material so small they start to exhibit quantum properties. The group has produced a detailed analysis of the electrical characteristics of the so-called double-quantum-dot SETs, which could help researchers design better devices to manipulate single electrons. They report their findings in the Journal of Applied Physics.

Extending a Battery's Lifetime with Heat
American Institute of Physics (AIP)

Over time, the electrodes inside a rechargeable battery cell can grow tiny, branch-like filaments called dendrites, causing short circuits that kill the battery or even ignite it in flames. But thanks to new experiments and computer simulations, researchers from the California Institute of Technology have explored in detail how higher temperatures can break down these dendrites — and possibly extend battery lifetimes. They discuss their findings in this week’s Journal of Chemical Physics.

Controlling Evaporative Patterning Transitions
American Institute of Physics (AIP)

The primary mechanism behind evaporative patterning has long been known: water evaporates faster at the edges of drops, which gives rise to a fluid flow carrying dissolved substances all the way to the edges. There, aggregates form, leading to residual patterns. But how does the transition between different patterning occur? Can we control patterning by altering the dynamics? A team from Harvard University explored these questions and describes their findings in the Physics of Fluids.

Origins of Life: New Model May Explain Emergence of Self-Replication on Early Earth

One question of the origin of life in particular remains problematic: what enabled the leap from a primordial soup of individual monomers to self-replicating polymer chains? A new model published this week in The Journal of Chemical Physics, proposes a potential mechanism by which self-replication could have emerged. It posits that template-assisted ligation, the joining of two polymers by using a third, longer one as a template, could have enabled polymers to become self-replicating.

Now, new research shows that a fish's propulsion can be understood by studying vortices in the surrounding water as individual units instead of examining the flow as a whole.
