Unraveling the stripe order mystery

August 20, 2019

One of the greatest mysteries in condensed matter physics is the exact relationship between charge order and superconductivity in cuprate superconductors. In superconductors, electrons move freely through the material—there is zero resistance when it’s cooled below its critical temperature. However, the cuprates simultaneously exhibit superconductivity and charge order in patterns of alternating stripes. This is paradoxical in that charge order describes areas of confined electrons. How can superconductivity and charge order coexist?

Jumping genes shed light on how advanced life may have emerged

November 19, 2018

A previously unappreciated interaction in the genome turns out to have possibly been one of the driving forces in the emergence of advanced life, billions of years ago.

This discovery began with a curiosity for retrotransposons, known as “jumping genes,” which are DNA sequences that copy and paste themselves within the genome, multiplying rapidly. Nearly half of the human genome is made up of retrotransposons, but bacteria hardly have them at all.

Researchers engineer bacteria to exhibit stochastic Turing patterns

How did the zebra get its stripes, or the leopard its spots? Mankind has been trying to answer such questions since our earliest recorded days, and they resonate throughout the extant mythologies and folklores of an earlier world. In modern times, we've looked to mathematical models and most recently to genomic science to uncover the explanation of how patterns form in living tissues, but a full answer has proven particularly hard to get at.

Reach out and feed someone: Automated system finds rapid honey bee networks

“Only connect”—E. M. Forster’s pithy quotation captures an essential feature of any society, human or animal: the patterns of interactions among individuals out of which collective behaviors arise. By developing a system that allows automated, in-depth monitoring of the social interactions of honey bees, researchers have now uncovered an unexpected property of the bee social network that may someday help us design more effective human and machine communication systems.

Virus-bacteria coevolution solves diversity paradox by 'Killing the Winner'

January 2, 2018

There is remarkable biodiversity in all but the most extreme ecosystems on Earth. When many species are competing for the same finite resource, a theory called competitive exclusion suggests one species will outperform the others and drive them to extinction, limiting biodiversity. But this isn’t what we observe in nature. Theoretical models of population dynamics have not presented a fully satisfactory explanation for what has come to be known as the diversity paradox.
