CognitionThe Marshmallow Study revisited
For the past four decades, the "marshmallow test" has served as a classic experimental measure of children's self-control: will a preschooler eat one of the fluffy white confections now or hold out for two later? Now a new study demonstrates that being able to delay gratification is influenced as much by the environment as by innate ability.

Fox squirrels show long-term investment savvy when hoarding nuts
Researchers at the University of California, Berkeley, are gathering evidence this fall that the feisty fox squirrels scampering around campus are not just mindlessly foraging for food, but engaging in a long-term savings strategy. Humans could learn something about padding their nest eggs from squirrels' diversification efforts. Of course, with squirrels, it's not about money, but about nuts.

ZooKeysNew fanged dwarf dinosaur from southern Africa ate plants
With tiny 1-inch long jaws, a new species of plant-eater has come to light in rocks in southern Africa dating to the early dinosaur era, some 200 million years ago. This "punk-sized" herbivore is one of a menagerie of bizarre, tiny, fanged plant-eaters called heterodontosaurs, or "different toothed reptiles", that were among the first dinosaurs to spread across the planet.

Journal of Prosthetics and OrthoticsEgyptian toe tests show they're likely to be the world's oldest prosthetics
The results of scientific tests using replicas of two ancient Egyptian artificial toes, including one that was found on the foot of a mummy, suggest that they're likely to be the world's first prosthetic body parts.

Journal of Experimental BiologyChocolate makes snails smarter
Chocolate isn't usually on the diet for snails, but when Lee Fruson and Ken Lukowiak from the University of Calgary, became curious about the effects of diet on memory, they decided to try a flavonoid from chocolate, epicatechin (epi) on the pond snail Lymnaea stagnalis to see if it improved the animals' memories. After a dose of epi, the pond snails were able to remember a training protocol for longer and the memories were stronger.
