Mirror Neuron Forum - Some additional discussion - Part I

by Greg Hickok in Talking Brains

Now that people have had a chance to digest the recently published "Mirror Neuron Forum" (Perspectives on Psychological Science 6(4) 369–407) I think it would be useful to revisit some of the claims and counter-claims. I will start working through some of the points in a series of posts. Of course, my focus will be on the parts of the forum that I participated in, but if you have some comments and thoughts on any part of it, feel free to email me and I'll post it as "guest post".

I would li........ Read more »

Kickass Mutualisms: Lycaenids Ants

by Marc in Teaching Biology

The Lycaenidae (gossamer-winged butterflies) is the second largest family of butterflies, with ~5000 species, including some of the more famous butterflies, such as the Theclinae (hairstreaks), the Polyommatinae (blues) and the Lycaeninae (coppers). They are mostly found in the Old World (de Jong, 2003), where 28 of the 33 lycaenid tribes are endemic. They are [...]... Read more »

The “Yellow Snow” Test for Self-Recognition

by Paul Norris in AnimalWise

The mirror self-recognition (MSR) test has long been used to assess whether an animal is self-aware, whether it has a sense of self. In the classic version of the test, a colored mark is placed on an animal’s body in such a way … Continue reading →... Read more »

Slacker Wrap-Up Part I: Eau de Toilette (Literally)

by Kelsey in Mauka to Makai

Hi, my name is Kelsey and I’m a slacker. (Note: Pete has progressed past the slacker phase into delinquency.) I will try to redeem myself—slowly. I have a whole slew (like five) of completely researched and partially written posts. After careful deliberation, I’ve decided that three of them are keepers. I’ve also decided that if [...]...

Cow-like Mealybug Home to Sexy Symbiotic Machine

by Jennifer Frazer in The Artful Amoeba

If it goes around on six legs, it doesn’t get much dowdier than the mealybug.* Powdery, bovine, and frightening if you find them binging on your gardenias, these wax-shedding roving syringes are one of many mosquito-like parasites that plague plants. Yes, sexy, mealybugs are not — unless you look inside them. There, you will find [...]... Read more »

MBA – Major Bad Ass?

Are business schools bad for business? Are they to blame for the demise in good management practices because they have become obsessed with teaching maximizing shareholder value at the expense of everything else? Perhaps they are. If so, is there a way out? [ ... ]... Read more »

Anterior cervical spinal cord surgery and dysphagia severity

by Adam in slowdog

I received a Google alert the other day on something about dysphagia and something about spinal cords. Naturally I was curious and scuttled to the source. A few clicks later I had myself a free journal article looking at dysphagia severity after anterior cervical (AC) surgery. Not quite ground breaking research, but interesting nonetheless. The study aimed “to determine the degree of dysphagia preoperatively and postoperatively in patients undergoing AC [anterior cervical] surgery compared........ Read more »

Religious differences and murder

by Tom Rees in Epiphenom

Most research into religion looks at how it influences attitudes towards co-religionists. But the flip side to religion is that it can also serve as a foundation for social divisions, in a similar way to ethnic and language barriers.

You might think this could increase social tensions, but new research by Don Soo Chon, at Auburn University at Montgomery, Alabama, suggests that this may not be the case. He looked at how the level of ethnic, linguistic, and religious fragmentation relates to hom........ Read more »

Why Reindeer Don’t Go Snowblind

by Jim Ryan in Wild Mammals

Polar explorers and the Inuit often experience photokeratitis, a painful eye condition commonly referred to as snow blindness. It is caused by prolonged exposure to ultraviolet (UV) rays from the sun reflecting off a landscape of white snow. The Inuit of the Arctic solved this problem by fashioning snow goggles from caribou antlers (Rangifer tarandus); similar goggles were later adopted by many polar explorers.

School Refusal: Exploring Why Children and Adolescents Refuse School

by Anita M. Schimizzi, Ph.D. in Child-Psych

Wow!  It’s really that time of year again.  While there are a range of thoughts and feelings that students have about heading back to school, it is the students that have a true phobia about attending that I hope to reach in this post.  Hopefully, this will find its way to parents that have seen [...]...

With these beautiful words starts a recollection paper by the founder of arXiv, Paul Ginsparg.

Stick with shade, clothes and sunscreen to prevent skin cancer – not coffee

by Cancer Research UK in Cancer Research UK - Science Update

Today, a new study has led to headlines claiming that adding caffeine to sunscreen could improve its effectiveness in preventing skin cancer. But don’t chuck away the sunscreen just yet, nor pour your coffee into it – this was an interesting study in mice, but it doesn’t prove that adding caffeine to sunscreen would have any effect [...]...

Top 73 idea portals

by David Bradley in Sciencetext

Since the 1990s companies and other organizations have created so-called “idea portals” for their customers and employees. These websites are aimed at gleaning new ideas and feedback for new products and services, new features and ways to improve processes. They are to all intents and purposes the online equivalent of the “suggestion box”. In recent [...]Post from: David Bradley's Sciencetext Tech TalkTop 73 idea portals

Tuesday Crustie: Cool

by Zen Faulkes in NeuroDojo

Uca panacea, a fiddler crab, whose specific name refers to a goddess of healing.

When I gave a public talk earlier this year about fiddler crabs, I talked at length about the role of the large claw in signalling. Signals from males to females, signals from males to other males, deceptive signals, and more.

A new paper suggests we might have been overlooking another use of this large claw: control its temperature.

Crabs are ectotherms: they rely on using the environment around them to change ........ Read more »

Boosting the “good” fat: Kids may lead the way

by Nancy Fliesler in Vector, a Boston Children's Hospital blog

Just as there’s good cholesterol and bad cholesterol, good carbs and bad carbs, there’s also good fat. Whereas white fat stores energy, padding our hips, thighs, arms and bellies, brown fat — studded with energy generators known as mitochondria – burns energy. Newborns have a ring of brown fat around their necks, helping them stay warm. By adulthood, it’s detectable in only 3 percent of men and 7.5 percent of women, with higher rates among younger and thinner peopl........ Read more »

Free language choice?

An Achilles’ heel?

by Zen Faulkes in Marmorkrebs

Last week, at my Ecological Society of America talk, one of the questions asked afterwards was, “Could the fact that Marmorkrebs are genetically identical be exploited to control introduced, unwanted populations?”

I said, “No.”

One of the things I admire about crayfish is that they are tough little survivors. Unfortunately, this means that they are hard to get a handle on once they’re loose.

I think it’s fair to say that the weapons used to control crayfish populations are blunt i........ Read more »

Some of us experience bigger 'emotional hangovers', whether from fun activities or hurricanes

by Alex Fradera in BPS Occupational Digest

While some of us may be generally happier than others, all of us experience different emotions from day to day. A fascinating new study suggests that these fluctuations are due to two factors: a cycling of emotion levels across the working week, and our unique personal sensitivity to both good and bad daily events. The study even has hurricanes.

Daniel J. Beal and Louma Ghandour from Rice University set out to track the daily affect patterns of participants from an IT services company. They wer........ Read more »
