Some deep-seafloor microbes still alive after 100 million years!
Some starving microbes nap while awaiting their next meal. For some living miles below the ocean surface, that nap may exceed 100 million years.
Siberian heat wave that caused an oil spill made more likely by climate change
The six-month heat wave in Siberia during the first half of 2020 would not have happened without human-caused climate change, researchers find.
These crocodile ancestors lived a two-legged life
A set of 106-million year old footprints show a crocodile relative appears to have walked on two legs.
Lightning megaflashes set big new distance and duration records
Scans of satellite images identified two lightning bolts with previously unheard-of dimensions. Both flashed through the skies over South America.

This dinosaur was no bigger than a hummingbird
The skull of one of these ancient birds — the tiniest yet known — was discovered encased in a chunk of amber originally found in Myanmar.
Study appears to rule out volcanic burps as causing dino die-offs
New data on when massive volcanic eruptions happened do not match when the dinosaur mass extinction took place.
Blood vessels in their heads kept big dinos from overheating
Giant dinosaurs evolved several ways to cool their blood and avoid heatstroke.
Powerful storms may be causing ‘stormquakes’ offshore
A perfect-storm mixture of hurricane, ocean and seafloor structures can create distinct seismic signals that have now been named ‘stormquakes.’
