Stars defy black hole by showing stable orbits around Sagittarius A*

Stars defy black hole by showing stable orbits around Sagittarius A*

An international research team led by PD Dr. Florian Peissker at the University of Cologne has used the new observation instrument ERIS (Enhanced Resolution Imager and Spectrograph) at the Very Large Telescope (VLT) facility in Chile to show that several so-called "dusty objects" follow stable orbits around the supermassive black hole Sagittarius A* at the center of our galaxy.

An unusually 'sticky' RNA class that keep cells organized: Researchers discover smOOPs

An unusually 'sticky' RNA class that keep cells organized: Researchers discover smOOPs

Inside cells, RNAs and proteins form tiny, liquid-like droplets called biomolecular condensates. These droplets are essential for organizing cellular life, yet why some RNAs cluster more readily than others has remained unclear. Disruptions in condensate formation are linked to developmental defects, cancer, and neurodegenerative diseases.

Nanostructured coatings physically puncture bacteria to prevent biofilm formation

Nanostructured coatings physically puncture bacteria to prevent biofilm formation

Bacteria that multiply on surfaces are a major headache in health care when they gain a foothold on, for example, implants or in catheters. Researchers at Chalmers University of Technology in Sweden have found a new weapon to fight these hotbeds of bacterial growth—one that does not rely on antibiotics or toxic metals.
