There is no permanent good in this world. One minute, everything seems fine. The next minute, the forces of darkness steal away Chantek, the beloved, 39-year-old signing orangutan.

Humans are the only animals known to develop Alzheimer’s disease, an age-related brain disorder that causes impaired cognitive functioning and other behavioral problems. Or at least, that’s what we thought. For the first time ever, researchers are claiming to have found signs of the disease in the brains of elderly…

This week, Bhagavan “Doc” Antle, the founder of The Institute for Greatly Endangered and Rare Species, posted an Instagram video of a chimpanzee wearing an HTC Vive virtual reality headset. There’s no sound, but the brief clip shows the chimpanzee sweeping its hands across the headset and reaching out to grab at the…

There is hope for original ideas in Hollywood after all! Isaac Adamson’s Black List-topping script told from the point of view of Michael Jackson’s pet chimp, Bubbles, will be made into a stop-motion animated film produced by Community’s Dan Harmon.

Nature is not known for its tender compassion. But for the very first time, biologists have captured footage of a chimpanzee mother in the wild caring for her severely disabled child. The infant lived for only 23 months.

A group of chimpanzees has been observed eating clay. Scientists think that they’re after the clay because it contains a very important element that helps neutralize problematic parts of their diet.

The Jane Goodall Institute, in collaboration with other animal welfare groups, has successfully petitioned the U.S. Fish and Wildlife Service to declare a new rule under which all chimpanzees—both wild and captive—must be protected as an endangered species.

Turns out that African apes and humans have more in common than previously thought. Observations made in the jungles of Guinea show wild chimps sipping alcoholic tree sap from leaf sponges, followed by some characteristically drunken behaviors.

Earlier today, a NYC judge heard arguments on the rights of two chimps being used for science experiments. During the two-hours of proceedings, the president of the Nonhuman Rights Projects described the chimps as “autonomous and self-determining beings.” A decision on their fate is expected in one to two months.

For the first time in U.S. history, a supreme court has granted a writ of habeas corpus on behalf of two lab chimpanzees, effectively recognizing them as legal persons. While the future of the chimps has not yet been decided, it’s a huge step forward in establishing personhood status for highly sapient animals.

This remarkable video was shot as part of a 29-month study of chimps crossing what’s often a dangerously busy road in Uganda’s Kibale National Park. Unlike in studies conducted of quieter roads, here the apes cautiously looked both ways, moved rapidly, and made sure all in the group made it across safely.

If the history of lobotomy itself weren’t infuriating and horrifying by itself, the development of the procedure would be. Because the experiment that gave Antonio Egas Moniz the idea for the lobotomy in the first place was actually a partial failure, yet Moniz chose to focus on the “positive.”

Tommy the chimpanzee got his day in court on October 8, 2014. He was unable to attend the hearing in 'person' – spending the day, like any other, in a cage in Gloversville, New York. But in an Albany courtroom, Steven Wise of the Nonhuman Rights Project argued that Tommy should be considered a person under New York…

Referred to as "referential calls," chimps use different grunts to identify objects. A new study provides the first evidence for vocal learning in non-humans, showing that chimps have the capacity for not just words — but also the ability to adapt to a new vernacular.
