Why Psychology 101 Should Be Evolutionary Psychology
by Jesse Marczyk in Pop Psychology
In two recent posts, I have referenced a relatively-average psychologist (again, this psychologist need not bear any resemblance to any particular person, living or dead). I found this relatively-average psychologist to be severely handicapped in their ability to think about … Continue reading →... Read more »

Homeostatic platsicity in a thorny situation
by TheCellularScale in The Cellular Scale
Synapses, the connections between neurons can strengthen and weaken depending on the specific activity at that synapse. This is called synaptic plasticity, and we've talked about it a lot on this blog (here, here, here and here).the strengthening and weakening of synaptic connections corresponds to the spine growing or shrinking (Matsuzaki 2007)However, there is another kind of plasticity that can occur at synapses. This is called homeostatic plasticity. And instead of the synapse strengthening ........ Read more »

Strategies for Breaking Even on Home Energy Consumption Suggested

Eye of the Tiger
by Denise O'Meara in A dribble of knowledge
A new genetic study by Mondol et al. 2013 examines the contemporary and historical genetic diversity of Indian tigers. They have found that the large reduction in the population has also wiped out many of the mitochondrial DNA haplotypes that were historically present, and the remaining populations are becoming more isolated and at greater risk for future extinctions. Mondol et al. 2013 is currently freely available!... Read more »

Transitioning from Adolescent to Adult Eating Disorder Treatment Programs: What Are The Challenges?
by Andrea in Science of Eating Disorders
Navigating health service systems can seem daunting, to say the least. Making phone calls, getting doctor appointments and referrals, attending intake appointments, and preparing oneself for treatment can be both mentally and physically draining. When children and adolescents develop eating disorders, their parents become the main navigators in this scenario, making decisions and arrangements for their under-18-year-olds. But what happens when these adolescents reach the age of 18, and sti........ Read more »

I Am Not This Body
by Perikis Livas in Tracing Knowledge
Every time I look at my face in a magnified mirror in a hotel bathroom, I jump back in surprise. Seen closely, my skin looks like the surface of a strange planet. Ridges and canyons pock my chin and lips. Forests of tiny hairs grow from my ear lobes. Unnoticed pimples rise from my nose like volcanoes. A sheen of oil coats the landscape. I half expect to see alien creatures living in minute settlements in my dimples or roving the great plains of my cheeks — and could I look at higher magnif........ Read more »

Friday Roundup: This Week's Wildlife Links (May 17th, 2013)

This article could use a little more reflection about working alongside potentially dangerous animals and a little less sensationalism. But, it's still an incredible story: I was swallowed by a hippo.
Who knew? Snakes like hot springs too.
The Roundup from a couple weeks ago featured amazing pictures of a pod of Orcas attacking a group of Sperm Whales. This week's unlucky victim is a dolphin.

Colour costs crickets
by Zen Faulkes in NeuroDojo
You probably don’t feel tired when you get a tan.
You probably think your friends feel more or less fatigued depending on whether they are dark skinned or fair skinned (like myself).
We know that differences in colour are important lots of other species besides humans. They can play a big part in an animal’s ability to blend into the surrounding environment, for instance. What might be less appreciated is that being a certain colour might take energy. After all, many colours in animals are........ Read more »
