Delay of Gratification in Kids and Crows
One measure of self-control is the ability to delay gratification; namely, the ability to wait in order to obtain a more valuable outcome in the future over a less valuable immediate one. In children, the capacity to delay gratification develops between the ages of three and five years old. In a new study, researchers used a rotating tray apparatus that allowed them to test both three- to five-year-old children and New Caledonian crows.

Vaping Guidelines
Centers for Disease Control (CDC), the Food and Drug Administration(FDA), state and local health departments, and public health andclinical partners are looking into a multistate outbreak of lung injuryassociated with the use of electronic cigarette (e-cigarette), orvaping, products.
Now, a report by a working group of experts offers guidance to health care providers caring for patients with EVALI (e-cigarette, or vaping, product use associated lung injury).
See that they say in my latest research summary for Pediatrics Nationwide: Health Care Leaders Offer Interim Guidelines on Vaping, EVALI Care.
Dogs Demonstrate Episodic-Like Memory
In humans, episodic memory refers to the recall of a specific autobiographical event – a memory of what happened, where it happened, and when it happened. It was initially assumed that episodic memory is unique to humans, but more recent evidence has brought that assumption into question.
Although we can’t know whether an animal travels back in time in their mind to subjectively remember specific events, like humans do, experiments have revealed memories for what-where-when in animals such as birds, rats, and nonhuman primates -- and now a new study suggests dogs should also join the club.

Vampire Bat Friendships
Mutual grooming and blood regurgitation form the basis of vampire bat friendships, which can last for years. And new research shows that relationships forged in captivity can persist once bats are back in the wild.
