Scientists analyzed groupings of juvenile Megalodon teeth, found in quarries in Tarragona province, which suggest an ancient nursery. Bone remains indicate the enormous prehistoric sharks did not reach maturity until age 25, so such sites may have been essential to their survival.


A melting mountainside ice patch revealed more than 60 arrow shafts, along with arrowheads and other artifacts, dating from 4100 B.C. to A.D. 1300. Scientists also found that almost 300 shards of reindeer antler or bone had accumulated there, suggesting the location was a prime hunting area.


New research suggests that when female banded mongooses are in heat, they encourage fights between their own groups and rival ones—and mate with enemy males in the ensuing chaos.


Scientists found that some Fritillaria plants have evolved gray and brown camouflage to match rocks in their mountainous habitats—especially in areas where herbalists have heavily harvested them for use in traditional medicines.


A landing capsule from Japan's autonomous Hayabusa2 spacecraft, carrying a cache of material gathered from asteroid Ryugu, successfully came down in South Australia's Woomera Prohibited Area. The spacecraft probed the asteroid from 2018–2019, and after this drop-off near Earth it continues to another asteroid mission.


Researchers fitted a GPS tracker on the world's last known white giraffe, an adult male, aiming to protect it from poachers. A white female and calf were killed in the same conservation area last March.
