The Mother Theresa Stamp and the Cultural Legacy of Postage

by Krystal D'Costa in Anthropology in Practice

Unveiling of the Mother Theresa postage stamp Sept. 5th, 2010 at the National Shrine. Postmaster General Jack Potter was in attendance (immediately to the left of the stamp).

Over the recent Labor Day weekend, S and I visited Washington D.C. where purely by chance we stumbled on a stamp unveiling. We were touring the National Shrine—the mosaics are breathtaking—when we realized the ceremony occurring at the front had little to do with normal services.  The United States Post Office h........

The Pelican’s Beak: Success and Evolutionary Stasis

by Laelaps in Laelaps

As a relatively infrequent airline traveler, packing for distant assignments and trips always presents me with an organizational challenge. Clothes, equipment, and supplies must be tracked down and stuffed into my cheap luggage, with frequent checks of the TSA website to ensure that I can unpack and repack my carryons with a minimum of hassle [...]...

Viral Talk!

by Mariam Rizkallah in Micro Writers

When you have to make a tough decision, a difficult choice, one that will affect your life and the lives of those around you, you always have to involve them in the process, and you will find that the wisest thing to do is to unite and make the decision collectively… Starting from us, humans, [...]...

Medical students keep quiet about depression because of fear of stigma

by Helen Jaques in In Sickness and In Health

Not only are a considerable proportion of medical students depressed, those who are believe they’ll lose the respect of their peers and their tutors if they speak out, according to new research in published in Journal of the American Medical Association. The study of 505 medical students in Michigan found that more than one in [...]... Read more »

Belgium – Famous for Chocolate and Explaining Pain Biology

by Lorimer Moseley in BodyInMind

Not an immediately obvious pairing, but still a bit more logical than a shop I once visited in UlaanBataar that sold saucepans, fur coats and guns (actually now that I think about it – one could shoot the elk, skin it and cook it up – quite the sensible shop after all). These Belgians have [...]... Read more »

The blind leading the blind…tandem running in visually impaired ants

by Dr. Carin Bondar in Dr. Carin Bondar - Biologist With a Twist

‘Tandem Running’ in ants is a behavioral strategy in which one ant leads another to a specific resource.  This kind of behavior has received a lot of attention from the scientific community because it represents a rudimentary form of teaching and learning.  Leaders ‘teach’ their followers how to find the prize, and the followers in [...]...

Protein clock stands the test of time

by Lucas in thoughtomics

When it comes to ancient times, biologists are pretty sloppy timekeepers. They measure time with something that they call the ‘molecular clock‘. Since every gene will undergo small mutations over time, they simply look at the number of differences between two genes of two different species to estimate how long ago they shared [...]...

Attack of the Giant Archaea

by Iddo Friedberg in Byte Size Biology

Archaea are under-rated. For one, most people don’t really know they exist – and if they do archaea are thoughtof as a type of bacteria. This goes not only for the general public also for some of my non-microbiology colleagues. (I had to correct quite a few “achaeobacteria” utterances .) The discovery that Archaea are a separate domain of life, as far from bacteria as we are, has never properly embedded itself in the way people commonly perceive life. There are some mitig........

Ladybusiness anthropology: Physical activity and prevention of reproductive cancers

by Kate Clancy in Context & Variation

I use PubMed to make RSS feeds out of searches on topics relevant to my research, because I cannot be trusted to regularly look this up on my own (I also have feeds from many of the main journals in my field, natch). One of my searches, “inflammation endometrium,” turned up an interesting article today from the European Journal of Cancer. Friedenreich et al review the literature on physical activity and cancer prevention and find a consistent relationship between physical activity and reduce........ Read more »

One flood. Three days - One canyon.

by Sarah Stephen in Our Gossamer Planet

We often get glimpses into the overwhelming power of nature. One such was in June-July 2002 in Texas: Fearing the worst during torrential rains, the waters of Canyon Lake (a reservoir on the Guadalupe River) were diverted into an emergency spillway. The consequential flood event, with a flow rate of over 1450 cubic metres per second and duration of six weeks, destroyed a bridge and trees, and carved a 2.2 km long, 7 m (average) deep canyon into the limestone bedrock. This new Canyon Lake Gorge i........ Read more »

OUCH! First ID of proteins involved in pressure-type pain

by Casey Rentz in Natural Selections

Ouch! I just pinched my finger in the silverware drawer...again. The signal travels up my peripheral nerve fibers, contacts nociceptors, and proceed into my thalamus, insular cortex (which  distunguishes pain from things like itch and cold), and other places in my brain. Soon, I'm shouting PAIN! PAIN! PAIN! But, until now, scientists had nothing but guesses as to the molecular domino that starts the cascade of effects. What happens directly after a pinch?

One team of scientists may have a ........ Read more »

Stressful Live Events and Suicide

by William Yates, M.D. in Brain Posts

The role of stressful life events in suicide attempts and completed suicides has been a key area of study in the epidemiology of mental disorders.  Although suicidal behavior often occurs in the context of acute and chronic stressor, this does not prove a causal link.  We all could probably report serious life stressors throughout out lives and these could be interpreted as a reason for suicidal behavior.  So these associations could simply be a coincidence and not have anything t........

You Look Where I Look: Magic Tricks and Gaze Cues

by Psychology 379 bloggers in Cognition & the Arts

If you are like me you have always been intrigued by magic tricks and you try to figure out the secrets behind each trick. Magic tricks have to do with something called “gaze cues”. Gaze cues, the effect of you looking where I look, are exactly what magicians utilize in their tricks. One of the [...]... Read more »

Neck Wars, flightlessness in azhdarchids and more filling of Romer's Gap: SVPCA 2010

by Darren Naish in Tetrapod Zoology

I said I wouldn't do any conferences this year. But I lied, and have recently returned from the 58th Symposium on Vertebrate Palaeontology and Comparative Anatomy (SVPCA), this year held once again in Cambridge, UK. Compared to the enormous, sprawling SVP (= Society of Vertebrate Paleontology) meeting with its numerous concurrent sessions (last year held in England, but usually held in North America), SVPCA is tiny and tidy. So, ok, there's less content, but at least you get to talk to every........ Read more »

Proto-Fairness? Hints of Moral Thinking in Dogs

by Jason Goldman in The Thoughtful Animal

Cooperation and conflict are both a part of human society. While a good deal of the academic literature addresses the evolutionary origins of conflict, in recent years there has been an increased focus on the investigation of the evolutionary origins of cooperative behavior. One component of cooperative behavior that might be present in other animals is aversion to inequity. Some scientists have suggested that inequity aversion may itself be the main factor driving the enforcement of cooperati........ Read more »

The Making of a Tyrant

by Brian Switek in Dinosaur Tracking

Tyrannosaurus rex was an obligatory inclusion in every book and documentary about dinosaurs I saw as a kid. It was the tyrant king of all dinosaurs, the supreme predator of the end-Cretaceous, but for all its majesty no one could explain where it had come from. Along with its kin—such as Albertosaurus and Tarbosaurus—Tyrannosaurus [...]... Read more »

The Doctor Death Wish: Why are so many health workers the victims of violent attacks?

by Emily Anthes in Wonderland

Last week, 50-year-old Paul Warren Pardus decided to express how he felt about the medical care being provided to his ailing mother. So he shot her doctor. Then he barricaded himself in his mother’s room at Johns Hopkins Hospital. When police found him, he had shot both himself and his mother to death. Her surgeon, Dr. David B. Cohen, had been shot in the abdomen and is expected to survive.... Read more »

The Mouse With Sleeper Toxins

by Rob Mitchum in ScienceLife

Studying a disease using an animal model is not as simple as merely replicating it. For instance, a variety of techniques have been used in animals to simulate the neurological disorder multiple sclerosis, where the protective myelin sheath that wraps around neuronal axons is lost, but each method has its advantages and disadvantages. Scientists have [...]... Read more »

Language, Thought, and Space (IV): Comparing Different Cultures

by Michael in A Replicated Typo 2.0

In my last post on the relationship between language, thought and (thinking and talking about) space I wrote that one of the most interesting, but also one of the most difficult questions is to what extent linguistic differences in talking about space reflect conceptual and perceptual differences.
