A composite image showing our Galaxy, the Milky Way, rising above the Engineering Development Array at the Murchison Radio-astronomy Observatory in Western Australia. The location of the centre of our Galaxy is highlighted alongside the ionized hydrogen (H+) signal detected from this region of sky. The white-blueish light shows the stars making up the Milky Way and the dark patches obscuring this light shows the cold gas that is interspersed between them.

Breaking the symmetry in the quantum realm

For the first time, researchers have observed a break in a single quantum system. The observation--and how they made the observation--has potential implications for physics beyond the standard understanding of how quantum particles interact to produce matter and allow the world to function as we know it.

The figure describes the dynamics of two spins as a harmonious couple-dance. Different from a solo-dance of a single spin, the couple-dance would present more unique and charming features, such as parity-time symmetry breaking demonstrated in the work.

Scientists break record for highest-temperature superconductor: Experiment produces new material that can conduct electricity perfectly

University of Chicago scientists are part of an international research team that has discovered superconductivity--the ability to conduct electricity perfectly--at the highest temperatures ever recorded.

Data science helps engineers discover new materials for solar cells and LEDs

Engineers at the University of California San Diego have developed a high-throughput computational method to design new materials for next generation solar cells and LEDs. Their approach generated 13 new material candidates for solar cells and 23 new candidates for LEDs. Calculations predicted that these materials, called hybrid halide semiconductors, would be stable and exhibit excellent optoelectronic properties.

Astronomers Capture First Image of a Black Hole

eso1907a_0.jpg
The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.

'Deep learning' casts wide net for novel 2D materials: Rice U. engineers show faster techniques to model atom-flat materials for bottom-up design

Scientists are discovering new two-dimensional materials at a rapid pace, but they don't always immediately know what those materials can do.
