A new study suggests that given the choice, many dogs prefer praise from their owners over food. The study is one of the first to combine brain-imaging data with behavioral experiments to explore canine reward preferences.

Generally seen as antithetical to one another, evolution and religion can hardly fit in a scientific discourse simultaneously. However, in a new article, a biology researcher delves into observations on the influences a few major religions have had on evolutionists and their scientific thinking over the centuries.

Self-consciousness: Beyond the looking-glass and what dogs found there

Dogs (and probably many other animals) have a conscience too!

Dogs (and probably many other animals) have a conscience too!

That man’s best friend has a conscience is what every owner would be willing to bet, without even thinking about it for a moment. This means that dogs have self-consciousness. But the problem in science is that ideas and assumptions must be demonstrated. It is not enough for someone to have an inkling of something for it to be considered a scientific fact. Self-awareness, or self-consciousness, has been studied mainly by examining the responses of animals and children to their reflection in the mirror.

Mans best friend: Dogs process faces in specialized brain area

How Dogs React to Faces vs. Everyday Objects

The study involved dogs viewing both static images and video images on a screen while undergoing fMRI. It was a particularly challenging experiment since dogs do not normally interact with two-dimensional images, and they had to undergo training to learn to pay attention to the screen.

Ever feel like your pet knows what you look like? While historically animals are depicted as, well slow… new research is proving otherwise. To pet owners this might not be big news, but scientists found that dogs have a specialized region in their brains for processing faces. The research provides the first evidence for a face-selective region in the temporal cortex of dogs.

Women’s faces get redder at ovulation, but human eyes can’t pick up on it

Womans face during ovulation

Previous studies have shown that men find female faces more attractive when the women are ovulating, but the visual clues that allow this are unclear. Now, new research investigating whether it might be to do with subtle changes in skin colour has shown that women’s faces do increase in redness during ovulation, but the levels of change are just under the detectable range of the human eye.

Cats are increasingly earning themselves a reputation as wildlife killers with estimates of animals killed every year by domestic cats in the UK numbering into the millions.

Many of the world’s largest herbivores — including several species of elephants, rhinoceroses, hippopotamuses and gorillas — are in danger of becoming extinct. And if current trends continue, the loss of these animals would have drastic implications not only for the species themselves, but also for other animals and the environments and ecosystems in which they live, according to a new report by an international team of scientists.
