Materials like carbon nanotubes (CNTs) and graphene reduce spacecraft weight while enhancing durability against radiation, extreme temperatures, and the vacuum of space. These improvements lower ...

We report here the discovery of the smallest possible carbon nanotube. This has a diameter of 4 Å, which is the narrowest attainable that can still remain energetically stable, as predicted by ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...

A new study reports that 34 percent of the Arctic-boreal zone (ABZ) is actually releasing more carbon than its storing, and that number climbs to 40 percent when considering wildfires. While this ...

It might seem like a distant memory now, but it's worth remembering that every major federal party ran in 2021 on a platform that included a consumer carbon tax. Nearly every single Liberal ...

Recent advances in ultrathin 2D materials — which are only a molecule thick — have created promising candidates for computer chips that pack much more power into much less space. 2D ...

Rocket bodies tend to be massive and heat resistant, posing an increased risk. Space debris from rocket bodies orbiting Earth is posing an increased threat to aircraft while falling from space ...

So, it can be hard to imagine that a compelling open-world game can keep players engaged even if it boasts 2D visuals. Plenty of video games let you play the role of a Samurai, but not many let ...

"In 2024, we saw a 17% year-over-year spike in the average number of close approaches in low Earth orbit per satellite." An international group of researchers is calling on the United Nations to ...

GlobalFoundries will create a new center for advanced packaging and testing of U.S.-made essential chips within its New York manufacturing facility. A flurry of announcements on advanced ...
