Quality of 3D printing with lunar regolith varies based on feedstock

Lately, there’s been plenty of progress in 3D printing objects from the lunar regolith. We’ve reported on several projects that have attempted to do so, with varying degrees of success. However, most of them require some additive, such as a polymer or salt water, as a binding agent. Recently, a paper from Julien Garnier and […]

Light signature algorithm offers precise insight on viral proteins, brain disease markers and semiconductors

Researchers at Rice University have developed a new machine learning (ML) algorithm that excels at interpreting the “light signatures” (optical spectra) of molecules, materials and disease biomarkers, potentially enabling faster and more precise medical diagnoses and sample analysis.

Compact optical clock uses quantum interference for improved frequency stability

An atomic clock research team from the National Time Service Center of the Chinese Academy of Sciences has proposed and implemented a compact optical clock based on quantum interference enhanced absorption spectroscopy, which is expected to play an important role in micro-positioning, navigation, timing (μPNT) and other systems.

P160C fires up successfully, a new chapter for Ariane 6 and Vega launchers

The P160C qualification motor was successfully tested on 24 April at the European Spaceport in French Guiana, on the solid-propellant booster test stand (BEAP) operated by the French Space Agency (CNES). The successful test firing of the first P160C motor is a major milestone in the development of the future upgrades of Europe’s Ariane 6 […]

Vesta’s missing core shatters long-held beliefs about the asteroid

For decades, scientists believed Vesta, one of the largest objects in our solar system’s asteroid belt, wasn’t just an asteroid and eventually concluded it was more like a planet with a crust, mantle and core. Now, Michigan State University has contributed to research that flips this notion on its head.

Using ‘shallow shadows’ to uncover quantum properties

It would be difficult to understand the inner workings of a complex machine without ever opening it up, but this is the challenge scientists face when exploring quantum systems. Traditional methods of looking into these systems often require immense resources, making them impractical for large-scale applications.

First observation of non-reciprocal Coulomb drag in Chern insulators reported

He Qinglin’s group at the Center for Quantum Materials Science, School of Physics, has reported the first observation of non-reciprocal Coulomb drag in Chern insulators. This breakthrough opens new pathways for exploring Coulomb interactions in magnetic topological systems and enhances our understanding of quantum states in such materials. The work was published in Nature Communications. […]

Life on Earth-like planets may emerge rapidly once conditions are favorable

An astronomer at Columbia University is suggesting that because life emerged so soon on Earth after its formation, it may emerge rapidly on Earth-like planets after the right conditions arise in general.

Searching for the dark in the light on Mars

Perseverance has been busy exploring lower “Witch Hazel Hill,” an outcrop exposed on the edge of the Jezero crater rim. The outcrop is composed of alternating light and dark layers, and naturally, the team has been trying to understand the makeup of and relationships between the light and dark layers.
