Behavior can be affected by events in previous generations which have been passed on through a form of genetic memory, animal studies suggest. Experiments showed that a traumatic event could affect the DNA in sperm and alter the brains and behaviour of subsequent generations. Show More Summary
by Rev. Michael P. Orsi November 24, 2013 (The American Spectator) - Human Exceptionalism, the belief that humans hold a unique status in the order of creation, has been the cornerstone of Western civilization. This understanding of human life is attested to in Genesis, the first book of the Bible. And, as some rabbis contend,…
Birds get a lot of attention for their use of tools. Clever animals, birds. But non-avian reptiles are capable of equally complex behaviors. Recent observations of crocodiles and alligators have revealed that both use twigs as hunting lures. A poetic twist: The sticks are used to lure birds. (WHO'S THE CLEVER ONE, NOW?) Read more...
Corvids — the family of birds that includes ravens, crows and magpies — are highly intelligent animals that are known for sharing many behavioral characteristics with primates, despite being only very distantly related. Tool use, planning,...Show More Summary
This kind of consumer frenzy is not at all out of order. The public would be disappointed if the animal spirits were indeed absent from the core of this national spectacle. And those who express disgust at this kind of behavior, the wild animal spirits of the consumer, are only contributing to this spectacle. Show More Summary
Brooding is a usual behavior in animals. However, to observe it in a marine worm is exceptional and, more surprisingly, it guards eggs from external threats.
An African safari needs no hype nor hyperbole; it's easily one of the most incredible experiences of a traveler's life. In Tanzania's Serengeti National Park (especially in the dry season), you are absolutely guaranteed to see most of the animals from your childhood ABC's book. Show More Summary
Aging and elderly animals are important in many social systems, including human households, but their role is influencing the behavior of others is often ignored. A recent photo essay about "the beauty and dignity of elder animals" and...Show More Summary
Biologists call it “mast.” Deer call it food. To hunters, it is one key to understanding game animals’ behavior. What is this stuff? Acorns, mostly. Wildlife biologists refer to fruits produced in forests, woodlands, and other habitat as “mast...
Researchers have developed a system to image brain activity in multiple awake and unconstrained worms. The technology, which makes it possible to study the genetics and neural circuitry associated with animal behavior, can also be used as a high-throughput screening tool for drug development targeting autism, depression, and other brain disorders.
A professional in animal behavior has created an easy-t […] The post Good Bird! A Guide to Solving Behavioral Problems in Companion Parrots appeared first on PetLvr Blog for Pet Lovers.
A father's cocaine use may make his sons less sensitive to the drug and thereby more likely to resist addictive behaviors, suggests new findings from an animal study presented by Penn Medicine researchers at Neuroscience 2013, the annual meeting of the Society for Neuroscience. The study, led by Mathieu Wimmer, PhD, a post-doctoral researcher in the laboratory of R...
New human and animal research just released demonstrates how experiences impact genes that influence behavior and health. These studies, presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's...Show More Summary

To survive, animals must explore their world to find the necessities of life. It's a complex task, requiring them to form them a mental map of their environment to navigate the safest and fastest routes to food and water. They also learn to anticipate when and where certain important events, such as finding a meal, will occur. Show More Summary
People are not the only ones who can be afflicted with eating disorders -- other animals, including cats, can be too. Behavior such as overeating, not eating enough, and chewing and swallowing non-food items are examples of eating disorders that can affect cats. Show More Summary
The puzzling, apparently wasteful habit of some animals to exert force in the direction opposite of where they want to go actually has an important purpose: to increase both stability and maneuverability.
A quirk of nature has long baffled biologists: Why do animals push in directions that don't point toward their goal, like the side-to-side sashaying of a running lizard or cockroach? An engineer building a robot would likely avoid these movements because they seem wasteful. So why do animals behave this way? read more
In today's comments, we looked at some behavioral glitches in the animal kingdom, read physics journals with the hope of seeing the TARDIS in there (and it was!), and learned some fascinating new details about the world of theoretical materials science. Read more...
