Dirty air is killing people and causing illnesses, but it’s also making people dumber. A new study shows that air pollution is linked to a clear and drastic decline in cognitive performance among almost 32,000 subjects.
Chickens have the ability to present distinct personalities, outmaneuver one another, determine specific order of things and reason by deduction.
A new study from the University of Oxford revealed that the further turtle doves and reed warblers traveled, the more new neurons they had in their brain. Interestingly, however, researchers found the neurons are utilized for different purposes.
Inhibitory control, or the ability to wait for a treat, may be a good indicator of how well your pooch can solve a problem.
Using a specialized IQ test, researchers examined the "general intelligence" of border collies. Since dogs and people have a lot in common, researchers suggest their findings could lead to improved diagnosis and treatment of human disorders, such as dementia.
There is more to determining an animal's intelligence than brain size. A new study from the University of Toronto found an ancient rodent species had a large brain that was even heftier than those of some primitive primates of the same era, but it wasn't necessarily "smarter."
It's no secret that ravens are exceptionally intelligent birds. Featured in myth and legend as doom-sayers, tricksters, and magical familiars, the wit of the raven is well known. Now new research has found that ravens are even capable of solving tasks that require coordinated cooperation -- an ability only a handful of hyper-intelligent species are capable of.
Previous studies have tied your ability to remember to things like marijuana use, depressive thoughts, and even your gender. But now new research has found that body posture may affect your memory as well as learning.
Neanderthals may have seemed brutish and dumb, but they certainly had style. A new study has shown that before the prehistoric humanoids mysteriously disappeared from the face of the Earth, they were wearing eagle talons as jewelry on their bodies.
It took millions of years of evolution for us to develop complex language and culture, and now scientists have discovered a "big brain" gene that may have been responsible for our unique human intelligence, according to a new study.
Insect-eating pitcher plants found in Borneo may seem brainless, but these carnivorous plants are cleverer than you think, a new study says.
Crows have long been considered highly intelligent animals, but now new research shows that they're even smarter than we thought and can actually think rationally, just like humans.
"Plant intelligence" is a term that's been thrown around a lot these days, especially by a number of scientists. But plants can't really think - or can they? Plants do indeed show signs of "intelligent" behavior, and even learn from interacting with what is around them.
It has long been accepted that many birds are notably clever creatures. Crows , for instance, are practiced thieves who keep track of where people hide food and shiny valuables. They can even be taught to use vending machines. Now a new study has found strong evidence that robins are also clever birds, and can even count.
Researchers have determined that many fish, like the relatively tiny zebrafish, are actually very good at focusing on multiple objects simultaneously, understanding what they are seeing and interacting with these objects in displays that contradict the popular impression of a "three-second memory."
