Nerve cells (yellow) from the same parent cell are organized in 3-D columns that extend through the layers of the gut wall. Credit: Reena Lasrado Scientists have made an important step in understanding the organisation of nerve cells embedded within the gut that control its function — a discovery that could give insight into the

This is an artistic view of the decay of a quantum-mechanical monopole into a Dirac monopole. Credit: Image by Heikka Valja. Scientists at Amherst College (USA) and Aalto University (Finland) have made the first experimental observations of the dynamics of isolated monopoles in quantum matter. The new study provided a surprise: the quantum monopole decays

The newly discovered Elfin mountain toad (Ophryophryne elfina) is in its natural habitat. Credit: Nikolay A. Poyarkov Jr. Deep in the foggy, moss-covered forests of Southern Vietnam, herpetologists uncovered one of the smallest species of horned mountain toads. The name of the new amphibian (Ophryophryne elfina) derives from European mythology and translates to “elfish eyebrow

Physicists Steve Sabbagh and Jack Berkery in front of the National Spherical Torus Experiment-Upgrade (NSTX-U) Credit: Elle Starkman Physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have helped develop a new computer model of plasma stability in doughnut-shaped fusion machines known as tokamaks. The new model incorporates recent findings gathered

The tip of an AFM pulling off a molecular chain vertically from a gold surface.

A hydrogen bond forms between a propellane (lower molecule) and the carbon monoxide functionalized tip of an atomic force microscope. The measured forces and the distance between the oxygen atom at the AFM tip and the propellane’s hydrogen atoms correspond precisely to the calculations.

Human activities have been changing near-Earth space and weather. Credit: NASA’s Goddard Space Flight Center/Genna Duberstein Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us. Space weather — which can include changes in Earth’s magnetic environment — are usually triggered by the sun’s activity,

Setting up. The standard inverted microscope is upgraded to a high quality live imaging station. Credit: Linda Koffmar SA recent study from Uppsala University shows how smartphones can be used to make movies of living cells, without the need for expensive equipment. The study is published in the open access journal PLOS ONE, making it

This is a view of the Mediano anticline, strata dipping to the left into the lake waters. This large-scale fold structure is a witness of ancient deformation associated with the rise of the Pyrenees in the middle Eocene, 45 Million years ago. Excellent exposure of rocks in this dry area allow today’s geologists to study

ow the host shapes the microbiota is unclear. This visual abstract depicts the findings in Liu et al, who identify host miRNAs within feces and show that these miRNAs are predominantly produced by gut epithelial cells and Hopx+ cells. These microRNAs can regulate bacterial gene expression and growth, and their loss results in imbalanced microbiota
