Medieval blue dye's molecular structure identified

A team of researchers affiliated with several institutions in Portugal has identified the molecular structure of folium, a blue watercolor dye used by medieval artists and book publishers. In their paper published in the ...

Molecular oxygen detected in the nearest quasar

Observations using the IRAM 30 meter telescope and the NOEMA Interferometer have unveiled the presence of molecular oxygen in Markarian 231—the nearest known quasar. The finding, detailed in a paper published on the arXiv ...

Driving massive galaxy outflows with supermassive blackholes

Active galactic nuclei (AGN) are supermassive black holes at the centers of galaxies that are accreting material onto their hot circumnuclear disks, releasing the energy in bursts of radiation or as particle jets moving at ...

Photocatalytic hydrogen production from water

NUS chemists have developed carbon-conjugated covalent organic frameworks for visible light-driven catalytic production of hydrogen gas from water.

Galaxies as 'cosmic cauldrons'

Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly inefficiently. Most of the gas is dispersed by stellar radiation, revealing galaxies to be highly dynamic ...

Star formation in galactic centers

Stars form from the gas and dust in molecular clouds via a series of complex processes that are currently only partly understood, and the evolution of these clouds drives the evolution of the stellar populations in the universe. ...
