Dinosaur-Killing Asteroid Impact Turned Ants into Fungus Farmers, Study Says
In a new study published this week in the journal Science, researchers found that fungus-ant agriculture originated approximately 66 million years ago when the end-of-Cretaceous asteroid impact temporarily interrupted photosynthesis.

Meteorite which wiped out the dinosaurs also created record-breaking hydrothermal system
The meteorite which caused the extinction of the dinosaurs also created an underground environment suited to supporting new life, and new research suggests it lasted for millions of years longer than previously suspected.

* 🦖 The meteorite that wiped out dinosaurs 66 million years ago also created a record-breaking hydrothermal system lasting at least 8 million years.
* 🔬 New research, analyzing samples from the Chicxulub crater in Mexico and using advanced computer modeling, suggests this underground system, conducive to life, persisted for four times longer than previously thought.
* 🌍 These findings, published in Communications Earth & Environment, shed light on how life may have originated in early Earth's hydrothermal systems and could guide the search for life on other planets.

Dinosaur-killing asteroid also created a dust cloud that insulated Earth, ‘charbroiling’ Cretaceous creatures
Purdue planetary scientists Brandon Johnson and Alexandria Johnson discovered that the Chicxulub impact created a global dust cloud that smothered the atmosphere, trapped heat and “charbroiled” species.

🔥 Sixty-six million years ago, an asteroid impact created a dust cloud that trapped heat, essentially "charbroiling" Earth's surface and causing widespread spontaneous combustion, population collapse, and atmospheric contamination.
☁️ The planet-smothering dust cloud, composed of particles 2.5 micrometers in diameter (30 times smaller than a human hair), prevented heat from escaping into space, leading to intense thermal radiation that was 17 times the lethal dose for humans.
🌍 This global heat and darkness, described as "looking more like hell than like Venus," led to massive wildfires and a global extinction event, with only creatures able to shelter underground or underwater surviving the initial cataclysm.
