Using the Mayall 4-meter telescope at Kitt Peak National Observatory, an international team of astronomers has observed C-19—an extremely metal-poor stellar stream in the Milky Way's halo. Results of the observational campaign, ...

The European Space Agency announced Thursday it has re-established communication with a spacecraft that is part of its Proba-3 mission, after losing contact with the satellite a month ago.

Plowing, or tilling, is an age-old agricultural practice that readies the soil for planting by turning over the top layer to expose fresh earth. The method—intended to improve water and nutrient circulation—remains popular ...

When the H5N1 highly pathogenic avian influenza virus was discovered on a poultry farm in Asia in 1996, there was little indication that it would become so widespread and so destructive. Within 30 years, it reached every ...

Researchers at UCLA have discovered a way to dramatically improve how electrical current enters perovskite semiconductors, an emerging class of materials with enormous potential for next-generation electronics. Their research ...

The Nanomedicine and Nanotoxicology Group (GNano) at the University of São Paulo's São Carlos Institute of Physics (IFSC-USP) in Brazil has discovered a way to transform hydroxyapatite, a bioceramic material, into a nanoparticle ...

Skyrmions, in which electron spins inside a magnet are arranged like vortices, are a key structure in next-generation spintronics technology. KAIST researchers have shown that skyrmions can form using only the fundamental ...

Researchers at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) have developed a revolutionary new method to improve compact gene-editing tools known as base editors, which enable smaller, ...

Milkweed has found a new strategy in its epic evolutionary battle with monarch butterflies: upgrading its toxins to outmaneuver the monarch's resistance. In a new study, published in the Proceedings of the National Academy ...

Imagine that plants could tell us exactly when they're stressed, infected, or being eaten by insects, by lighting up. A new study led by Dr. Karen Sarkisyan, Head of the Synthetic Biology group at the MRC Laboratory of Medical ...

Controlling light at the micro- and nanoscale opens up opportunities for a better understanding of the world and the development of technology. As modern electronics approaches the limits of its capabilities, photonics comes ...

A colony of leafcutter ants is home to more than just one species. Each year, studies reveal new layers of complexity in these ecosystems, where various fungi and bacteria thrive alongside the ants, resulting in countless ...
