Fish recognize faces

Damselfish can recognize members of their own species by their unique facial patterns, detectable to us only under ultraviolet light. The fish were tested under conditions where they were rewarded for swimming toward an image of a fish-face they had seen before over a novel image. They overwhelmingly picked familiar faces. Since fish swim in groups, it may benefit them to know their neighbors.

Also, the title of the article should be "Not just a human skill!" - as it is surprisingly not a human skill...

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.

Bees need a break after all that social time

Bees sleep more after hanging out with bees than they do after spending time alone - five hours more! It could be the flood of information they have to process after encounter so many of their colony members - the extra sleep may help with learning and memory. Read more here!

Stress makes birds friendlier

Feeding corticosterone (a stress hormone) to zebra finches had the opposite effect of what scientists expected - it made the birds MORE social, but those "friendships" were more fleeting than those exhibited by control birds, who spent more time with family and closer friends. Read more about the recently published study here.

Why is there an alpaca in my grocery store?

What is the deal with emotional support animals? For the record, they are not the same thing as a service animal - but there's a lot of confusion about what is allowed and what isn't - and it's easy to fake a letter. Patricia Marx goes undercover and explores what happens when you bring a "therapy turtle" to a museum. Read here!

"Thanks for the ride, lady"

(That's a line from Creepshow 2, in case you don't remember)

Scientists using camera traps with motion sensors weren't surprised to find a variety of animals among the nighttime photos in a South African park. But they were a little surprised to find a tiny mongoose relative, called a genet, using both rhinos and buffalos as a means of transport. The same genet was seen riding on the backs of several animals, in the same evening. Lazy or innovative? Or both?
