NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is rich with detail.

Thousands of galaxies—including the faintest objects ever observed in the infrared—have appeared in Webb’s view for the first time. The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it.

Webb’s Near-Infra Red Cam has brought those distant galaxies into sharp focus—they have tiny, faint structures that have never been seen before, including star clusters and diffuse features.

The rapid movement of lithium ions along the 2D vertical channels in the T-Niobium oxide (T-Nb2O5) thin film results in unique property changes and a chase transition. The blue and purple polyhedra show T-Nb2O5 lattices, without and with lithium, respectively. The bright green spheres represent lithium ions.

The European Space Agency’s latest astrophysics mission, Euclid, lifted off on a Space X Falcon 9 from Cape Canaveral in Florida, USA, at 17:12 CEST on 1 July 2023. Euclid has now started its month-long journey to Sun-Earth Lagrange point L2, located 1.5 million kilometers from Earth, in the opposite direction from the Sun.

Masoud Akbarzadeh of the Weitzman School of Design leads a multidisciplinary group of architectural designers, structural engineers, computer scientists, and more in his Polyhedral Structures Laboratory. He explores ways in which polyhedral geometries that frequently occur in nature can be used to make stronger and lighter structures, all while using fewer materials. Akbarzadeh discusses a recent study drawing inspiration from dragonfly wings.

Michael Mann, Penn’s inaugural Presidential Distinguished Professor in the Department of Earth and Environmental Science and collaborators found that the effects of climate change on the intensity, frequency, and duration of extreme weather events like wildfires, could lead to massive increases in all three.

The concept of a brain-computer interface was first proposed and experimented upon in the 1970s by Jacques Vidal, who demonstrated that humans could control a cursor on a computer screen using their brain waves.

“The air contains an enormous amount of electricity,” says Jun Yao, assistant professor of electrical and computer engineering in the College of Engineering at the University of Massachusetts Amherst, and the paper’s senior author. “Think of a cloud, which is nothing more than a mass of water droplets. Each of those droplets contains a charge, and when conditions are right, the cloud can produce a lightning bolt—but we don’t know how to reliably capture electricity from lightning. What we’ve done is to create a human-built, small-scale cloud that produces electricity for us predictably and continuously so that we can harvest it.”
