We're not going to discuss "the dress" or the great llama chase of 2015 (where was I yesterday?) ...but there's plenty else to talk about!
False memory in bumblebees
In an experiment that might be called "confuse a bee," bees were trained on two different stimuli that indicated a reward (a yellow flower, or a black and white striped flower). After training, they were given three flowers to choose from: one yellow, one black and white striped, and one YELLOW striped - combining qualities from the test stimuli. Bees chose the flower most recently rewarded.
A few days later, the bees started to chose the yellow striped flower, suggesting their memory was getting fuzzy and they were hedging their bets for a treat! Read more here.
Rats exploring a new environment do better with a buddy. Scientists measured rats second exploration of a novel space either alone or with another rat. Rats who had a buddy on that second trial were more exploratory, and the effect lasted through a third solo trial. Read more!
Whiskers in other mammals might serve a purpose similar to our hands and fingers - rats were shown using their whiskers to navigate and avoid obstacles, depending on the novelty and complexity of the environment. Read about the study here.
Nice write up of a study that found that albino rats would help struggling rats (by freeing them from a cell they were trapped in) of a different strain, but only if they'd been socialized with them; they will free rats of the same strain, regardless if they are a familiar or a stranger.
