Highly processed foods can be considered addictive like tobacco products

Can highly processed foods be addictive? It’s a question that researchers have debated for years as unhealthy diets are often fueled by foods loaded with refined carbohydrates and added fats.

Black hole announces itself to astronomers by violently ripping apart a star

A hitherto undiscovered black hole announced its presence to astronomers when it ripped apart and devoured a star that wandered too close to it. The intermediate-mass black hole located in a dwarf galaxy a million light-years from Earth shredded the star in an occurrence that astronomers call a Tidal Disruption Event (TDE). The TDE made itself visible when it blasted out a flare of radiation so powerful that it briefly outshone every star in its dwarf galaxy home combined.
