A new study published in Science shows that it is possible for bees to be optimistic, especially after being able to experience or indulge in sugar-concentrated water. The researchers want to find out if insects, just like people, are also capable of having positive emotions such as happiness.
Blue jays are adorned with striking blue feathers that never fade. It turns out birds are able avoid going gray – unlike humans – because their feathers contain sophisticated nanostructures that reflect light better than pigmentation.

A hawksbill sea turtle found off the coast of the Solomon Islands is the first biofluorescent reptile ever discovered. The sea turtle was "glowing" green and red as it swam by researchers observing corals in the Pacific Ocean.
Using fossilized structures known as melanosomes, researchers concluded that an ancient bat species was reddish-brown in color. More importantly, the study suggests that melanin desposits from fossils can be used to determine the color of ancient species.
Lizards use bright colors to attract mates but this also makes their camouflage less effective, making them visible to predators, report researchers from the University of Cambridge.
Squid are known as masters of disguise, and now their unique abilities are inspiring new camouflaging materials, according to a recent study.
Seven new teeny-tiny frog species have recently been discovered in the cloud forests of Brazil, and though they were just found, scientists already say that they are threatened and on the brink of extinction.
Color blindness affects a significant portion of the population, most notably men. And now, new research has identified a new gene mutation that could possibly cause this condition.
We all know that it's hard to keep up appearances when you're constantly on the go. That's why the fashion police will probably give some female warblers a free pass, even after researchers found that they boast drabber feather when their migration routes are particularly long.
Madagascar is known for its incredible biodiversity, but even so scientists were surprised to find that one species in particular that's unique to the region, called the panther chameleon, is actually 11 different species in one.
