Expressive elephants use gestures and vocal cues to communicate
Communication is more than just verbal cues. It’s also glances and gestures and many primates, including humans, use motions to convey their message.

Swarm of tiny snail robots stick together to form new structures
Researchers have built a swarm of miniature, snail-inspired robots, minus all the mucus. Instead, a retractable suction cup works in tandem with the remote-controlled machine’s tank-like treads to maneuver across both difficult terrain and over each other. Biomimicry is nothing new within the field of robotics. But while many aquatic…

Sperm whales may have their own ‘alphabet’
Sperm whales have their own unique cultures, accents, and potentially a phonetic alphabet. A team from MIT’s Computer Science & Artificial Intelligence Laboratory (CSAIL) and Project CETI (Cetacean Translation Initiative) may have decoded this phonetic alphabet that reveals sophisticated structures within sperm whale communication that could be similar to human phonetics…

Bigger-brained gull species thrive in urban spaces
Despite the reputation for being the trash pandas of the bird world, seagulls are kind of the masters of evolution. They can survive and thrive alongside humans, have a remarkable memory, and some have been observed using pieces of food to bait fish the way primates use tools. The seagull…

Orangutan observed using a plant to treat an open wound
Observers have documented multiple animal species using plants for self-medicinal purposes, such as great apes eating plants that treat parasitic infections or rubbing vegetation on sore muscles. But a wild orangutan recently displayed something never observed before—he treated his own open wound by activating a plant’s medical properties using his…

How saber-toothed cats’ baby teeth kept their adult fangs from breaking
The saber-toothed cats that once prowled modern day California had more distinct dental features than even their sabers would suggest. Some of the complete skulls had a tooth socket occupied by two teeth–a permanent saber tooth and a baby tooth that would eventually fall out. These double-toothed sockets may have…
