IN A NUTSHELL ✨ Recent research challenges the notion that the universe’s first stars were exclusively massive, suggesting more diverse masses. 💫 Studies reveal that turbulence and molecular coolants in early gas clouds could have led to the formation of lower-mass stars. 🔬 Helium hydride, the universe’s first molecule, played a crucial role in cooling gas clouds, enabling the formation …

Bacterial strains and growth conditions All strains, unless otherwise specified, were grown in Luria–Bertani (LB) at 30 °C with 200-rpm shaking. Antibiotic activity test strains and ESKAPE pathogens were: B. subtilis 168, S. aureus SH1000, E. coli ATCC 25922, E. faecium COM15, K. pneumoniae ATCC 10031, A. baumannii ATCC 17978, P. aeruginosa PAO1 and E. cloacae ATCC 13047. Sample collection In late May 2023, we collected samples from Rockefeller …

Using machine learning, MIT chemical engineers have created a computational model that can predict how well any given molecule will dissolve in an organic solvent — a key step in the synthesis of nearly any pharmaceutical. This type of prediction could make it much easier to develop new ways to produce drugs and other useful molecules. The new model, which …

This story was provided by Live Science, a sister site of Space.com. For the first time, researchers have recreated the universe’s first ever molecules by mimicking the conditions of the early universe. The findings shake up our understanding of the origin of stars in the early universe and “calls for a reassessment of the helium chemistry in the early universe,” …

A new study reveals that our muscles can produce a powerful anti-aging molecule. The molecule, called CLCF1, is released mainly during resistance training and seems to help preserve muscle strength, …

Astronomers have detected signs of complex organic molecules, the precursors to the building blocks of life as we know it, in a planet-forming disk around a distant star. The findings imply that the chemical seeds of life are constructed in space and are then spread to young or newly forming planets. Using the Atacama Large Millimeter/ submillimeter Array (ALMA), a …
