Twisted electronics open the door to tunable 2-D materials

more »
Researchers report an advance that may revolutionize the field of 2-D materials such as graphene: a 'twistronic' device whose characteristics can be varied by simply varying the angle between two different 2-D layers placed on top of one another. The device provides unprecedented control over the angular orientation in twisted-layer devices, and enables researchers to study the effects of twist angle on electronic, optical, and mechanical properties in a single device.

Hubble Paints Picture of the Evolving Universe

Astronomers have just assembled one of the most comprehensive portraits yet of the universe’s evolutionary history, based on a broad spectrum of observations by the Hubble Space Telescope and other space and ground-based telescopes. In particular, Hubble’s ultraviolet vision opens a new window on the evolving universe, tracking the birth of stars over the last 11 billion years back to the cosmos’ busiest star-forming period, about 3 billion years after the big bang. This photo encompasses a sea of approximately 15,000 galaxies — 12,000 of which are star-forming — widely distributed in time and space.

Sprawling galaxy cluster found hiding in plain sight

more »
Scientists have uncovered a sprawling new galaxy cluster hiding in plain sight. The cluster, which sits a mere 2.4 billion light years from Earth, is made up of hundreds of individual galaxies and surrounds an extremely active supermassive black hole, or quasar.

Study of material surrounding distant stars shows Earth's ingredients 'pretty normal'

more »
The Earth's building blocks seem to be built from 'pretty normal' ingredients, according to researchers working with the world's most powerful telescopes. Scientists have measured the compositions of 18 different planetary systems from up to 456 light years away and compared them to ours, and found that many elements are present in similar proportions to those found on Earth. This will have implications for finding Earth-like bodies elsewhere.
