Celestial objects known as dark dwarfs may be hiding at the centre of our galaxy and could offer key clues to uncover the nature of one of the most mysterious and fundamental phenomena in contemporary cosmology: dark matter. A new paper published in the Journal of Cosmology and Astroparticle Physics (JCAP) by a team of researchers based in the UK and Hawaii describes these objects for the first time and proposes how to verify their existence using current observational tools such as the James Webb Space Telescope.

 

Researchers have discovered a novel method to generate topological optical textures using a simple periodic photonic crystal slab. This breakthrough, published in Physical Review Letters, leverages Bound States in the Continuum (BICs) to create these textures in free momentum space without the need for precise alignment, offering a robust and scalable platform for next-generation information carriers.

Photoactivated ketones prove to be promising H-atom transfer photocatalysts for activating carboxylic acids and generating new C–C, C–S, and C–Cl bonds.

POSTECH and Linyi University develop ‘SLY,’ a Probe That Glows Yellow Only in Tumor Cells.

A research team combined metabolomic and transcriptomic analyses to uncover how brain chemistry regulates aggressive behavior.

Gut bacteria are known to be a key factor in many health-related concerns. However, the number and variety of them is vast, as are the ways in which they interact with the body’s chemistry and each other. For the first time, researchers from the University of Tokyo used a special kind of artificial intelligence called a Bayesian neural network to probe a dataset on gut bacteria in order to find relationships that current analytical tools could not reliably identify.
