Chimps show empathy by mimicking pupil size - life - 22 August 2014. Chimpanzees and humans may share the same ability to empathise with other individuals by involuntarily matching their pupil size.
The mimicry only appears to work between two humans or between two chimpanzees but not between species, suggesting the signalling reinforces social bonds within species. We already know that pupils change shape in response to a new, unfamiliar target: they tend to constrict initially and, after a fraction of a second, readjust and dilate. There's evidence that human pupils dilate more rapidly while adjusting if their owner is interacting with another human whose pupils are also dilating.

Chimpanzees teach youngsters to make tools. Even octopuses seem to be able to plan. So should we humans really be surprised that “consciousness” probably does not only exist in us? Bonobo genius makes stone tools like early humans did - life - 21 August 2012. Video: Watch this bonobo go to all ends to get food Kanzi the bonobo continues to impress.
Not content with learning sign language or making up "words" for things like banana or juice, he now seems capable of making stone tools on a par with the efforts of early humans. Eviatar Nevo of the University of Haifa in Israel and his colleagues sealed food inside a log to mimic marrow locked inside long bones, and watched Kanzi, a 30-year-old male bonobo chimp, try to extract it. While a companion bonobo attempted the problem a handful of times, and succeeded only by smashing the log on the ground, Kanzi took a longer and arguably more sophisticated approach.

Wocka-wocka-woo? " Chimp Groups Have Cultural Differences | Evolution of Tool Use & Culture | Chimpanzees. Like humans who might use a different slang term for "that's cool" or have distinct fashion sense, adjacent chimpanzee groups also show cultural differences, in this case, in their nut-cracking techniques, researchers have found.
"In humans, cultural differences are an essential part of what distinguishes neighboring groups that live in very similar environments," study researcher Lydia Luncz, of the Max Planck Institute for Evolutionary Anthropology in Germany, said in a statement. "For the first time, a very similar situation has been found in wild chimpanzees living in the Taï National Park, Côte d'Ivoire, demonstrating that they share with us the ability for fine-scale cultural differentiation. " Listen: The Rare, Beautiful Songs of Bowhead Whales | Wired Science. A bowhead whale breaches.
Photo: Kate Stafford The haunting sounds of bowhead whales, which sing their songs under Arctic ice through long, dark polar winters, have been recorded in unprecedented detail. The recordings reveal a vocal repertoire every bit as rich as better-studied humpback and sperm whales, and hint at complex social organizations and lifestyle patterns hidden until now by the bowheads’ extreme remoteness.
“We know relatively little about bowhead whales. Mothers Teach Chimp Kids 'Words' | Social Learning | Chimpanzee Vocalizations. Captive chimpanzees learn from their mothers to call out to humans, new research suggests.
Those chimps raised by their moms were also most likely to use similar calls, from lip-smacking to blowing kisses. This teaching from mother to child is an example of "social learning," which played an important role in the development of human culture and language.
Personality Might Be Genetically Encoded in Bee Brains. Tagged foraging bee, image courtesy of Zachary Huang/beetography.com Honeybees (Apis mellifera) are more than cookie-cutter drones, workers, foragers and queens.
They might have individual personality differences similar to our own, according to new research. After studying hives—both in the wild and in the lab—and analyzing genetic and biochemical profiles of bees’ brains, researchers have found that some bees, like some humans, seem to be programmed to seek out new experiences, or novelty. Forager bees are in charge of gathering food outside of the hive, but not all of these bees, it seems, are inclined to strike out and go exploring for new flowers. Only a subset of them—some five to 25 percent—actively scout out new pollen sources. Terrifying photos reveal first ever evidence of bears using tools.

Alex the Parrot's Posthumous Paper Shows His Mathematical Genius. From Nature magazine Even in death, the world's most accomplished parrot continues to amaze.
The final experiments involving Alex — an African grey parrot (Psittacus erithacus) trained to count objects — have just been published. They show that Alex could accurately add together two Arabic numerals to a sum of eight and the total number of objects under three cups, putting his mathematical abilities on par with (and maybe beyond) those of chimpanzees and other non-human primates. The work appears in the journal Animal Cognition. Terrifying sex organs of male turtles | Tetrapod Zoology. A Testudo tortoise and its large erect penis.
Of the many unlikeable and inaccurate stereotypes maintained about animals in popular consciousness, among the most frustrating is what I term “old man turtle”. This is the idea that turtles (by which I mean, all members of Testudines) are like decrepit, weak, bony little old men housed inside a box. It’s not fair, and it’s not at all accurate.
Here we look at just one aspect of turtle anatomy. Secret to Elephants' Thundering Calls Discovered | Vocal Cords & Voice. Elephants' deepest calls can thunder up to 6 miles (10 kilometers) away. Now, researchers have learned for the first time how the massive animals produce these sounds. It turns out that they do it in the same way that humans talk, pushing air through their vocal cords to make them vibrate. Elephants can go much lower than humans, however, because their vocal cords are eight times longer. "The sounds the elephants make are off the piano keyboard," said study researcher Christian Herbst, a voice scientist at the University of Vienna, Austria. In fact, at less than 20 hertz in frequency, the main components of these ultra-deep calls aren't detectable to the human ear.
Glaucus atlanticus. Descripción[editar] El tamaño normal de esta especie varía entre 3 y 4 cm de largo.  En su parte dorsal presenta una coloración azul plateada, ventralmente un azul pálido. Posee rayas azules oscuras o negras a lo largo del pie. Tiene un cuerpo troncocónico aplanado con seis apéndices que se ramifican en rayos cerata. Sus dientes con rádula se asemejan a espadas. Heartbreaking photographs capture the facial expressions of animals. While I am saddened by the fact that these animals are in peril in large part due to us, what really gets my blood pressure up is people that make comments along the lines you just did. You make it clear that the survival of an animal species is worth more than any person's life, so what are you doing about it? Are you part of the problem or part of the solution? It is.
