Gaia survey provides location and motion of 1.3 million binary pairs within 3,000 light years of Earth. A doctoral student has mined the most recent Gaia survey for all binary stars near Earth and created a 3D atlas of 1.3 million of them. The last local survey included about 200 binary pairs. With such census data, astronomers can conduct statistical analyses on binary populations. For pairs that contain white dwarfs, it’s possible to determine the age of their main-sequence companion, and thus of any exoplanets around them.

The latest star data from the Gaia space observatory has for the first time allowed astronomers to generate a massive 3D atlas of widely separated binary stars within about 3,000 l...

As electronic devices saturate all corners of public and personal life, engineers are scrambling to find lightweight, mechanically stable, flexible, and easily manufactured materials that can shield humans from excessive electromagnetic radiation as well as prevent electronic devices from interfering with each other.

In a breakthrough report published in Advanced Materials—the top journal in the field— engineers at the University of California, Riverside describe a flexible film using a quasi-one-dimensional nanomaterial filler that combines excellent electromagnetic shielding with ease of manufacture.

“These novel films are promising for high-frequency communication technologies, which...

Using NASA’s Chandra X-ray observatory, astronomers from the University of Alabama in Huntsville have investigated the central region of the galaxy NGC 1600, focusing on its ultramassive black hole (UMBH). Results of the study, presented in a paper published February 11 on the arXiv pre-print server, shed more light on the properties of this UMBH.

At a distance of about 150,000,000 light years away from the Earth, NGC 1600 is an elliptical galaxy in the constellation Eridanus...

A gene linked to unusually long lifespans in humans protects brain stem cells from the harmful effects of stress, according to a new study by Weill Cornell Medicine investigators.

Studies of humans who live longer than 100 years have shown that many share an unusual version of a gene called Forkhead box protein O3 (FOXO3). That discovery led Dr. Jihye Paik, associate professor of pathology and laboratory medicine at Weill Cornell Medicine, and her colleagues to investigate how this gene contributes to brain health during aging.

In 2018, Dr...
