The Delbouef Illusion is well known. It absolutely works on humans, but scientists wanted to see if it also works on monkeys. That’s harder to establish than it looks. How do you resist having illusions about your optical illusion test?
Are you in North America? Statistically speaking, yes. Do you like monkeys? Of course you do. Have you noticed that you live in an extremely monkey-poor region of the Earth? Well, here’s what ruined your chance to have monkeys hanging around in your hometown. Yes, I’m bitter too.
The Thatcher Effect is a well-known optical illusion, first tested with a picture of Margaret Thatcher. It's glaringly obvious, but humans almost always fall for it. So, it seems, do monkeys.
Talking to animals, including baby human animals, is a waste of time. They don't know what you're saying. But there has been an experiment that proves certain animals they do know what language you're saying it in.
An excerpt from Empire's Gremlins reunion is up on the magazine's website, and it includes the story about how they first tried using a monkey dressed as a Mogwai before settling on puppets. There was a lot of poop involved.
There has been a long tradition of employing animals in military operations. The latest example might be China's troop of macaque soldiers.
A recently concluded experiment shows that rhesus monkeys are capable of doing simple addition using numbers 1 through 25. But more interesting than that is the observation that they also make the same mistakes as us.
Scientists working in Brazil recently witnessed a heartbreaking scene involving a female marmoset who sustained a mortal head injury after accidentally falling from a tree. They then watched in amazement as her partner of three-and-a-half years climbed down to comfort her as she lay dying.
A long-running study is re-affirming the life-extending benefits of calorie-restricted diets. It overturns a study from 2012 indicating otherwise. The 25-year experiment shows that rhesus macaques, when eating 30% less than normal, are twice as likely to live beyond those who could eat whatever they want.
Looking to create more accurate experimental models for human diseases, biologists have created transgenic monkeys with "customized" mutations. It's considered a breakthrough in the effort to produce more human-like monkeys — but the ethics of all this are dubious at best.
Children who don't know better might throw spitballs or pull hair to get another child's attention, and it turns out that certain monkeys do something similar. Female capuchin monkeys have been observed throwing rocks at males as a form of courtship.
Yesterday, naturalist Sir David Attenborough participated in a reddit AMA, answering questions from the reddit community. One thing that he revealed during the Q&A was the most upsetting thing he has witnessed in his career: chimpanzees hunting monkeys.
Unlike all other primates, clawed New World Monkeys almost always give birth to twins. But why? It turns out these animals have a unique set of adaptations that make it possible — and could prove useful to humans as well.
New anthropological research on human behavior has found that when it comes to sexual selection, females aren't merely passive objects of male competition, but actively seek out multiple partners as an "evolutionary strategy." According to science, we're all sluts. Who wants to heave the first "told ya so"?
In the mid-1600s, green monkeys from Africa were introduced to the West Indies island of Barbados. Despite living a predator-free life for centuries, the Barbados population still responds to an ancestral alarm call that means, roughly translated, “Run up a tree or a leopard will eat you!”
Why must we constantly fear the supernatural when there's so much real stuff to fear? Take, for example, the many smart, dangerous groups of animals who escaped from their laboratory environments and now roam free. Perhaps they're just enjoying their liberty — or perhaps they're seeking revenge on those who caged them.
Plenty of animals have gone to space, but this monkey managed to find itself on the moon—and it appears that not all has gone well. What's this monkey's tale?
Power Rangers was made for children, in the ‘90s, and had a terrible small budget. Can someone really take a show to task for not being brilliant when it operated under such severe limits? When the episode is titled “A Chimp in Charge,“ I would posit you can and should.
Scientists have discovered fossils of two newfound primate species, dating back to 25 million years ago. One fossil belongs to the group that contains great apes (hominids), while the other is from the group that includes Old World monkeys. The discovery may mark the moment when our primate ancestors first diverged…
A new clip from M. Night Shayamalan's After Earth titled "Monkey Discovery" has been released. In it, young Jaden Smith does indeed discover a monkey, who is extremely upset at being forced to star in an M. Night Shyamalan film. Justly so, I think.
