Huntsman spiders eat tree frogs after luring them into leaf traps

Huntsman spiders in Madagascar eat tiny frogs, and scientists suspect that the spiders catch their prey by weaving “traps” made of leaves, to lure the frogs inside with a promise of protection from the sun. In 2017, researchers spotted a spider in the Damastes genus clutching a Heterixalus andrakata tree frog — the second time […]

The invasive species is so out of control in the state that the government may begin encouraging the new meal as a way to help keep the snake’s numbers under control, as long as they aren’t filled with toxic mercury.  Before […]

Astrocytes eat connections to maintain plasticity in adult brains — ScienceDaily

Developing brains constantly sprout new neuronal connections called synapses as they learn and remember. Important connections — the ones that are repeatedly introduced, such as how to avoid danger — are nurtured and reinforced, while connections deemed unnecessary are pruned away. Adult brains undergo similar pruning, but it was unclear how or why synapses in […]
