Manganese dioxide can convert amino acids into hydrogen cyanide (HCN) without requiring methane, a finding that solves a long-standing puzzle about the origin of this key prebiotic molecule on early Earth. Although HCN is central to origin-of-life theories, recent evidence suggests early Earth’s atmosphere didn’t contain sufficient methane needed for classic HCN-producing reactions. The newly […]

Using the Rozhen National Astronomical Observatory, Bulgarian astronomers have conducted optical photometric observations of an ultracompact binary known as GP Com. Results of the observational campaign, presented in the Proceedings of the Bulgarian Academy of Sciences, shed more light on the properties of this system.

You’re in the lab analyzing Martian regolith samples within your cozy Mars habitat serving on the fifth human mission to Mars. The power within the habitat has been flowing flawlessly thanks to the MARS-MES (Mars Atmospheric Resource & Multimodal Energy System), including the general habitat lighting, science lab, sleeping quarters, exercise equipment, the virtual reality […]

An international team of astronomers reports the discovery of a new supernova remnant (SNR) using radio observations. The newfound supernova remnant, dubbed Abeona, is one of the faintest radio SNRs so far detected. The discovery is detailed in a research paper published April 21 on the arXiv preprint server.

Shielding materials are essential in key modern industrial settings—such as spacecraft, nuclear power plants, semiconductor equipment, and advanced medical devices—to protect both equipment and personnel from electromagnetic waves and radiation. In particular, as space exploration gains momentum—such as with the successful launch of Artemis 2 on the 2nd—the importance of next-generation shielding technology capable of […]
