- Neuroscience
Chickadees use memory ‘bar codes’ to find their hidden food stashes
Unique subsets of neurons in a chickadee’s memory center light up for each distinct cache, hinting at how episodic memories are encoded in the brain.
- Paleontology
An extinct sofa-sized turtle may have lived alongside humans
Peltocephalus maturin was one of the biggest turtles ever, but unlike similarly sized prehistoric freshwater turtles, it lived thousands of years ago.
- Animals
Male dragonflies’ wax coats might protect them against a warming climate
The reflective wax, which cools males on sunny courtship flights, may also armor them against the effects of climate change.
- Life
This is the first egg-laying amphibian found to feed its babies ‘milk’
Similar to mammals, these ringed caecilians make a nutrient-rich milk-like fluid to feed their mewling hatchlings up to six times a day.
- Animals
Giant tortoise migration in the Galápagos may be stymied by invasive trees
An invasion of Spanish cedar trees on Santa Cruz Island may block the seasonal migration routes of the island's giant tortoise population.
- Plants
Ancient trees’ gnarled, twisted shapes provide irreplaceable habitats
Traits that help trees live for hundreds of years also foster forest life, one reason why old growth forest conservation is crucial.
- Animals
The first known scorpion to live with ants carries mini hitchhikers
Small arachnids hitch a ride on the scorpion, possibly to get inside food-rich ant nests.
- Life
Megalodon, the largest shark ever, may have been a long, slender giant
The ancient shark is typically imagined with the scaled-up stout frame of a modern great white. But in life, the giant may have been more elongated.
- Climate
Numbats are built to hold heat, making climate change extra risky for the marsupials
New thermal imaging shows how fast numbats’ surface temperature rises even at relatively reasonable temperatures.
- Animals
Why do some lizards and snakes have horns?
These reptiles’ horns can be an asset or a liability. A new study looks at the evolutionary roots of this wild headgear.
- Animals
These nesting penguins nod off over 10,000 times a day, for seconds at a time
Micronaps net chinstrap penguins over 11 hours of sleep a day, offering some rest while staying vigilant against predators and competitors.
- Life
Some picky Australian mosquitoes may target frog nostrils for blood
The insects seem to sip from nowhere else on frogs’ bodies. Thinner skin or denser blood vessels near the nostrils might explain why.
