Passive smoking: Acrolein inhibits immune defense and stimulates tumor growth
In Austria, two or three persons daily die as a result of passive smoking. The rate in domestic animals is unknown. Acrolein from the side stream smoke has now been described by Franziska Roth-Walter et al. It is first identified as the cause of the failure of the immune defense against tumors by passive smoking: it is stimulating the T-regulatory cells via the arylhadrocarbon receptor.
Janus-faced Acrolein prevents allergy but accelerates tumor growth by promoting immunoregulatory Foxp3+ cells: Mouse model for passive respiratory exposure.

Publication Dog Science: You spy with your little eye
Humans are able to interpret the behaviour of others by attributing mental states to them (and to themselves). By adopting the perspectives of other persons, they can assume their emotions, needs and intentions and react accordingly. In the animal kingdom, the ability to attribute mental states (Theory of Mind) is a highly contentious issue. Cognitive biologists from the Messerli Research Institute of the University of Veterinary Medicine Vienna could prove with a new test procedure that dogs are not only able to identify whether a human has an eye on a food source and, therefore, knows where the food has been hidden. They can also apply this knowledge in order to correctly interpret cues by humans and find food they cannot see themselves. This perspective taking ability is an important component of social intelligence. It helps dogs to cope with the human environment. The results have been published in the journal Animal Cognition.

Publication Kea Science: For This New Zealand Parrot, “Laughter” Is Contagious
When people are feeling playful, they giggle and laugh, making others around them want to laugh and play too. Now, researchers reporting in Current Biology on March 20 have found that the particularly playful kea parrot from New Zealand has a “play call” with a similarly powerful influence. When other kea hear that call, it puts them into a playful mood. The findings make kea the first known non-mammal to have such an “emotionally contagious” vocalization, the researchers say. Earlier studies had made similar findings for chimpanzees and rats.
