University of Pennsylvania researchers are now among the first to produce a single, 3-atom-thick layer of a unique 2D material called tungsten ditelluride. Unlike other 2D materials, scientists believe tungsten ditelluride has what are called topological electronic states. This means that it can have many different properties not just one. When one thinks about 2D materials, graphene is probably the first that comes to mind. The tightly packed, atomically thin sheet of carbon first produced in 2004 has inspired countless avenues in research that could revolutionize everything from technology to drinking water...

Kinematic Clues to Bar Evolution for Galaxies in the Local Universe: Why the Fastest Rotating Bars are Rotating Most Slowly. The Astrophysical Journal, 2017; 835 (2): 279 DOI: 10.3847/1538-4357/835/2/279

Fastest spinning bars are rotating most slowly because of dark matter. Why do the majority of astronomers believe in dark matter: matter whose composition is unknown but which seems to make up 80% of the mass of the galaxies? The concept was invented in the 1930’s by Fritz Zwicky who used it to explain why the galaxies in the Coma cluster are moving much more quickly than can be explained in terms of their known masses...

The Magellanic Clouds, the 2 largest satellite galaxies of the Milky Way, appear to be connected by a bridge stretching across 43,000 light years, according to an international team of astronomers led by researchers from the University of Cambridge. The discovery is based on the Galactic stellar census being conducted by the European Space Observatory, Gaia which scientists have been eagerly anticipating for 15 years. The first portion of information from the satellite was released 3 months ago and is freely accessible to everyone...

Scientists have uncovered key processes in the healthy development of cells which line the human gut, furthering their understanding about the development of cancer.

Scientists have uncovered key processes in the healthy development of cells which line the human gut, furthering their understanding about the development of cancer. A University of East Anglia (UEA) study shows that a protein called ninein is essential for normal tissue development in the gut. The research aimed to unravel some of the poorly-understood mechanisms involved in rearranging the cytoskeleton – in cells that are undergoing a shape change during normal development.

Using ‘mini-guts’ created in the lab, they studied the tubular filaments which are part of the cytoskeleton called microtubules, and their dramatic rearr...
