Can you change the behavior of a bear that raids campgrounds, nuzzles through trash, or knocks side view mirrors off cars? A new study finds evidence that a method called aversive conditioning can be successful in modifying the behavior of some bears but fully averting conflicts with humans will require changing how people act as well......

This one will be short, as I still haven't had the chance to sit down and go on an epic research blogging adventure. Let's glance at Kofoidia, an obscure hypermastigote parabasalian.It must think it's an Oligotrich ciliate of some sort. Poor deluded thing. Since I seem to gravitate towards obscure organisms mentioned in a single paper in all the literature available/mentioned online, there is but a sole lonely drawing of this organism: Parabasalid Kofoidia loriculata. Desperately in need of an S........ Read more »

Every now and again a finding comes along that provides perfect ammunition for psychologists confronted by the tiresome claim that psychology is all 'common sense'. Researchers have found that death-related health warnings on cigarette packs are likely to encourage some people to smoke. The surprising result is actually consistent with 'Terror-management Theory', according to which thoughts of mortality cause us to cling more strongly to our cultural beliefs and to pursue ego-boosting activities........

Pregnancy requires many adaptations to new situations. These changes are accompanied by massive neuroendocrine changes leading to adaptations organized by the mother’s brain. These changes are necessary for the different phases of pregnancy and motherhood.

It's all about the music.
Gill and Purves. "A biological rationale for musical scales" PLoS ONE, 2009
So you might think that music like this:
(HOT STUFF. Go to 0:35 for the real hotness. It's Victoria's O Magnum Mysterium)
(Also some killer hot stuff, 3:50 has the real chills. The Lauridsen version)
Don't have much in common with THIS hot stuff:

Bristlecone pines are famous as a candidate for the title of the oldest living things (it depends on what you count as a lifetime). The oldest is over 4,500 years old.

How do new species arise? That has got to be on of the most central and intriguing questions in evolutionary biology. Reproductive isolation is one of the prerequisites for speciation: if two populations keep intermingling, the populations will not diverge from one another. However, if populations become reproductively separated, both populations will eventually diverge and [...]... Read more »

Humans adapt their mating strategies according to what they think their chances are. For example, when there are more men than women, people marry earlier and divorce less. When there are more women, the opposite applies. The supposition is that this this is because, when women are in a 'buyers market' they are more able to demand fidelity.What's more, when women are shown an array of attractive, promiscuous women, they're more likely to reject the notion that casual sex is OK.How does religion ........

WE tend to assume that we see our surroundings as they really are, and that our perception of reality is accurate. In fact, what we perceive is merely a neural representation of the world, the brain's best guess of its environment, based on a very limited amount of available information. This is perhaps best demonstrated by visual illusions, in which there is a mismatch between our perception of the stimulus and objective reality.
Even when looking at everyday objects, our perceptions can be de........ Read more »

In most of the discussions of using usage as a metric of scholarly impact, the example of the clinician is given. The example goes that medical articles might be heavily used and indeed have a huge impact on practice (saving lives), but be uncited. There are other fields that have practitioners who pull from the literature, but do not contribute to it. So it was with interest that I read this new article by the MacRoberts: MacRoberts, M., & MacRoberts, B. (2009). Problems of citatio........ Read more »
