3D Systems announced two additions to its industry-leading materials portfolio – Certified Scalmalloy (A) and Certified M789 (A) – to facilitate demanding industrial high-strength, corrosion-resistant parts for additive applications in markets such as aerospace, motorsports & automotive, semiconductor, energy, and moldmaking.
General Atomics Electromagnetic Systems announced today that it has expanded its space systems infrastructure with the addition of a 7,500 ft2 Class 10,000 / ISO 7 cleanroom facility in San Diego, CA that will enable high-volume Optical Communication Terminal (OCT) production. The multifaceted facility can facilitate fabrication of up to 300 OCTs per year.
NASA and Boeing have decided to postpone the launch of Orbital Flight Test-2 to the International Space Station as teams continue work on the CST-100 Starliner propulsion system.
Technicians and engineers working to ensure the soundness of NASA’s James Webb Space Telescope (JWST) manually lower its folded sunshield layers for easier access and inspection. After being lowered, engineers thoroughly inspect all five layers of the reflective silver-colored sunshield for any issues that may have occurred as a result of acoustic testing.
Relaxor ferroelectrics, which are often lead-based. These materials have mechanical and electrical properties that are useful in applications such as sonar and ultrasound. The more scientists understand about the internal structure of relaxor ferroelectrics, the better materials we can develop for these and other applications.
The James Webb Space Telescope will observe primarily the infrared light from faint and very distant objects. In order to be able to detect those faint heat signals, the telescope itself must be kept extremely cold. To protect the telescope from external sources of light and heat (like the Sun, Earth, and Moon) as well as from heat emitted by the observatory itself
MIT researchers have designed a polymer material that can change its structure in response to light, converting from a rigid substance to a softer one that can heal itself when damaged.
gold nanoparticles, coated with a semiconductor, can produce hydrogen from water over four times more efficiently than other methods – opening the door to improved storage of solar energy and other advances that could boost renewable energy use and combat climate change, according to Rutgers University–New Brunswick researchers.
Neutrinos, Italian for “little neutral ones,” are often described as “ghost particles,” for their extremely weak interactions with ordinary matter. Indeed, billions of neutrinos stream through our fingernails every second, without ruffling so much as a molecule of matter. And yet, on Sept. 22, 2017, the IceCube Neutrino Observatory, based at the Amundsen-Scott South Pole Station, detected a neutrino in signals picked up by its detectors buried deep in the Antarctic ice. Researchers there quickly sent out alerts to ground- and space-based telescopes in hopes of finding the neutrino’s cosmic source.
X-Ray Experiment – Over the last decade, scientists have used supercomputers and advanced simulation software to predict hundreds of new materials with exciting properties for next-generation energy technologies. Now they need to figure out how to make them. To predict the best recipe for making a material, they first need a better understanding of how it forms, including all the intermediate phases it goes through along the way – some of which may be useful in their own right.

In the maze of our brains, there are various pathways by which neural signals travel. These pathways can go awry in patients with neurological and psychiatric diseases and disorders, including epilepsy, Parkinson’s, and obsessive-compulsive disorder. Researchers have developed new therapeutic strategies to more precisely target neural pathways involved in these conditions, but they often require surgery.
