Chaser, a Border Collie, has been shown to have learned the names of 1022 objects. The researchers working with Chaser showed that she not only remembered the names of the objects but was able to understand certain aspects of language.
John Pilley – a master animal trainer – was getting a new puppy in 2004, just as a German study was released on Rico, a dog who learned the names of 200 objects. Pilley decided to find the limits of dog intelligence, and began language training with Chaser when she was five months old. Chaser's training continued for three years under psychologists Alliston Reid and John Pilley.
While theoretically there is no problem, the physicist noted that in practice the universe does not have 330 quadrillion light years of space, nor the 1036 kittens required.
Roman Stocker, of MIT, was inspired by his cat, Cutta Cutta, to study how cats drink. Although humans are able to suck liquids, dogs and cats are unable to seal their cheeks and so need to lap. While dogs bend their tongue to form a scoop cats, both domesticate and wild, were found to use a different mechanism.
Recent research on how dolphins interact with one another has shown surprising levels of complexity. Groups of dolphins have been observed working together and dolphins of different species may even be able to communicate – or at least attempt to.
Science NOW reported on two dolphin papers showing social co-operation, while the BBC covered preliminary research on dolphin communication.
Creating a feline character? You might want to decide on their habitat before picking a coat.
[...] cats living in dense habitats, in the trees, and active at low light levels, are the most likely to be patterned.
The researchers admitted that this rule did not explain the coat of cheetahs, who have evolved spots despite a preference for open plains.
The team discounted suggestions that coat patterns in big cats were linked to social hierarchy or gender, as they did not differ significantly between such individuals. Their paper, Why the leopard got its spots, was published in Proceedings of the Royal Society B.
While foxes have the reputation of being sluts in the furry fandom, perhaps this title should rather fall to hares, who have been shown to have simultaneous pregnancies.
The hares show superfetation — the ability to become pregnant before giving birth from an earlier pregnancy. Scientists at the Liebniz Institute for Zoo and Wildlife Research found that pregnant European brown hares can become pregnant again about four days before delivery. This decreases the amount of time between litters and makes the hares capable of being permanently pregnant.
Bats in eastern parts of the United States and Canada are dying out from a new disease.
White-nose syndrome, named for the white fungi on muzzles and wings, makes bats restless, depleting their reserves of body fat during hibernation. The fungi – first found in February 2006 in a New York cave – are considered the likely cause of the disease.
According to a Wired article, biologist Winifred Frick said: "Yes, we had the empirical observations that cave floors were littered with dead bats. [...] But nobody had quantified the impact to the populations. We didn’t know what those die-offs meant to population viability as a species."
Frick and her colleagues analyzed the last 30 years of population data for the most common and most-studied species of bat in North America, the little brown bat (Myotis lucifugus). If recent trends continue, the researchers predict a "99 percent chance of regional extinction of little brown myotis within the next 16 years."
The list is taken from the 20 000 newly discovered species that are found each year and includes such organisms as a plant that eats rats and a fish with vampire fangs. It is a good start if you want to learn about the variety of living things in the world, and how little about them we know, or even if you just want to create a unique fursona.
Squirrels may be small, but are extremely complex creatures.
Squirrels will actively try to deceive people, pretending to hide their nuts when they think they are being watched, but actually keeping them hidden in their mouths. They have different calls for different things and can learn by watching other species, even humans. Physically they have a number of exceptional features, like the ability to jump ten times their body length.
Researchers studying meerkats have found different groups follow different traditions that are passed on non-genetically. They noticed that different meerkat groups wake up at different times, and that immigrants adjust to the group's traditional waking hour.
Not wanting to let Arizona get all the glory, the Ohio Senate has passed a bill banning the creation of "human-animal hybrids."
The same group previously explained how a newt used its ribs as poisonous barbs, puncturing its own skin and that of animal hoping to consume it.
Hyena giggles may convey important information about the age and status of individuals, as this BBC article explains.
Senate bill 1307, which passed 16-12, prohibits (among other things):
- creating or attempting to create an in vitro human embryo by any means other than fertilization of a human egg by a human sperm.
- creating or attempting to create a human-animal hybrid
- transferring or attempting to transfer a human embryo into a nonhuman womb
- transferring or attempting to transfer a nonhuman embryo into a human womb, and
- transporting or receiving for any purpose a human-animal hybrid
