Cats are liquid — if they choose to be

Science marches on! A new study shows that cats can be liquid, if they choose to be.

Fardin noticed that these furry pets can adapt to the shape of the container they sit in—think of a cat in a vase—similarly to what fluids such as water do. So he used the principles of rheology, the branch of physics that deals with the deformation of matter, to calculate cats’ relaxation time, or the time it takes for them to take up the space of a vase or bathroom sink.

The conclusion? Cats can be either liquid or solid, depending on the circumstances, Fardin reported in the Rheology Bulletin in 2014…. A cat in a small box will behave like a fluid, filling up all the space, but a cat in a bathtub full of water will try to minimize its contact with it and behave very much like a solid.

Anyone who has ever owned a cat will be understand this research. It isn’t that cats can be liquid that is expected, it is that cats will do what they want. If they want to be liquid, no one is going to stop them.

Because of this ground-breaking research, the scientist has won this year’s Ig Nobel Physics Prize.

How cats used humans to conquer the world

Link here. The bottom line is this:

Compared to many other animals, cats have also changed very little in the domestication process. Behaviorally, they’ve become more tolerant of humans. Physically, though, they’re still about the same size and shape. They still like to pounce on small prey. “Cats have done since before they were domesticated what we needed them to do,” says Leslie Lyons, a feline geneticist at the University of Missouri. In other words, unlike dogs that herd sheep or hunt badgers, cats didn’t need humans to breed them to become good mouse hunters.

In other words, cats did what they want (as they always do), and humans paid them with food and companionship, while providing them the transportation they needed to reach every continent.

Science discovers that cats prefer human companionship over food

News you can use: A new study has found that cats will choose human companionship over food if given a choice.

The researchers took 50 cats from shelters and peoples homes and deprived them of food, human contact, scent and toys for a few hours. They then introduced them to stimuli within these four categories to see what they chose.

Most cats chose human socialisation over any of the other categories.

From my perspective, what is even more important is that cats don’t choose those humans nonchalantly. Every cat lover knows that, unlike dogs, cats pick carefully whom they will love. But if they love you they show it.

How cats conquered the world

Link here. This first large scale study of the DNA of ancient cat remains tracks how felines initially spread through human society in the ancient world.

The article and the researchers appear to make one mistake, however, in questioning whether cats have been domesticated. Anyone who owns a cat can answer that question unequivocally: No! Cats merely agree to live with us, on the condition that we treat them as they demand.

Cats vs dogs in genome research

After an initial focus on studying the genomes of dogs, genetics researchers are now switching to cats.

After the completion of the human, mouse and rat genomes, the US National Institutes of Health organized a commission to decide on their next target; the dog genome was selected for high-quality sequencing, whereas cats were put on hold.

That got some cat geneticists’ backs up. “The truth is there were more powerful people interested in dogs,” says Stephen O’Brien, director of the Theodosius Dobzhansky Center for Genome Bioinformatics in St Petersburg, Russia, who led the initial cat-sequencing efforts.

There is now a project which, for only $7,500, allows scientists to map the genome of any cat for the cause of science. Under this program, they’ve already done 56 cats, including a kitten and her parents.

A new housecat-sized feline species has been discovered in Brazil.

A new housecat-sized feline species has been discovered in Brazil.

Oncillas are housecat-size felines found throughout much of South America, and are also known as little tiger cats, little spotted cats or tigrinas. But not all oncillas are the same: New research suggests that little tiger cats in northeastern Brazil belong to a different species from those elsewhere on the continent, although they look virtually identical.

Researchers analyzed the genetic material of oncillas in northeastern Brazil, and compared them with nearby populations in the south. They found that there was no flow of genes between the two populations of oncillas, and hasn’t been any for millennia, according to the study, published today (Nov. 27) in the journal Current Biology.

This, along with other genetic differences, led researchers to conclude the two populations do not interbreed and are in fact different species, said study co-author Eduardo Eizirik, a researcher at Pontifical Catholic University of Rio Grande do Sul in Brazil.

Cat purrs prevent heart attacks

Research has now shown that the purr of a cat appears to prevent heart attacks.

A 10-year study at the University of Minnesota Stroke Center found that cat owners were 40 per cent less likely to have heart attacks than non-cat owners. A cat at home reduced the risk of other heart diseases and stroke by 30 per cent.

But then, all cat owners have always known this.
