Wearing your religion on your face

by Doug Keene in The Jury Room

We’ve talked before about mock jurors believing they can ‘see’ who is lying, using drugs, or other negative behaviors litigants (or anyone else!) would want to keep private. Now we have new evidence that some of those jurors may have good radar—at least when it comes to being able to identify certain religious group members! [...]

by Erin Campbell in HighMag Blog

Cell migration is a complicated process, and the ease of genetic manipulation in the fruit fly Drosophila makes it an ideal organism for investigating the genes involved. Add some great live imaging to the mix, and you are a big step closer to understanding cell migration. Border cells are a cluster of migratory cells in the fly egg chamber that are required for proper fertilization of the egg and early patterning of the embryo. This group of 6-10 cells collectively moves to one end of the egg........ Read more »

How to cheat a brain-scan-based lie detector

by BPS Research Digest in BPS Research Digest

Cheating the scanner is relatively easy
Sure, it's possible to differentiate patterns of truth-telling brain activity from patterns of lying-related activity. But contrary to media hype, experts have been quick to point out that the accuracy of brain-scan based lie detection is often no better than with traditional approaches, such as the polygraph. Furthermore, these experts warn, brain-scan methods could, in theory, be easily thwarted by liars with even modest levels of guile. That........ Read more »

Oxytocin in Schizophrenia and Autism

by Dr Shock in Dr Shock MD PhD

Oxytocin is not the social panacea, it’s not a universal prosocial enhancer that can render all people social-cognitive experts. In my previous post Oxytocin was only of benefit to less socially proficient individuals not in more socially proficient individuals. So can it be useful for patients with schizophrenia or autism. Patients with schizophrenia with negative [...]

Clonal origins of Haiti’s Cholera epidemic

by Michelle Ziegler in Contagions

Haiti had been free of cholera for 50 years when the earthquake struck in January 2010. The destruction of Haiti’s infrastructure by the earthquake made it vulnerable to infectious disease outbreaks but it was hoped that cholera would pass it by. As we all know by now, this unfortunately has not the case. Cholera has [...]... Read more »

Tag-teaming research blogging: Me and Sci do it up, PMDD-style

by Kate Clancy in Context & Variation

When I was in college, my favorite hangout was the basement of the Harvard Book Store, where they had the used books and cheap remainders (they were also across the street from my freshman dorm, Wigglesworth, and yes, that is a most excellent name). I worked my way through several sci-fi and fantasy series, and got nearly all my Women’s Studies books, because of that one lovely room.One night in my freshman year I was browsing the philosophy section with a new boyfriend, a person with whom I o........

different aspects of the default mode network

by Janet Kwasniak in Thoughts on thoughts

The default mode network is not as simple as it seemed. There are probably several configurations. A recent paper (by D Stawarczyk and others) has looked at the difference between the default network when the subject is not attending to a task and when the subject is ignoring sensory stimulating from the outside world.

Sunday Protist – Gromia: beautiful predatory grapes of the sea

by Psi Wavefunction in Skeptic Wonder

And we're back. The protists and I, that is. Well, the protists never quite went anywhere but you know what I mean...You may have heard of Gromia a couple years ago when it hit the news by leaving tracks on the ocean floor resembling Ediacaran trace fossils (tracks). Or perhaps not; I tend to get overly excited the one time a year some protist makes the news. The giant (3cm) track-leaving Gromia in question sounded even cooler as it came from the great deep sea; other species of Gromia are in fa........ Read more »

Did the Red Fox Predate the Dog as Man's Best Friend?

by William Yates, M.D. in Brain Posts

Pets have longed played a role in human companionship.  Wild animals were primarily a source of food (and danger) in early human development.  Later in evolution,  animals began to serve a more complex role.  Domestication of a variety of animals served a more utilitarian role.  For example, domestication of horses allowed for extended travel, improved efficiency of hunting and provided a strategic advantage in battle.The domestications of wild wolves has been felt to be........

Supermassive black hole in a dwarf galaxy

by Charles Daney in Science and Reason

Supermassive black hole in a type of galaxy where nobody expected to find one? Henize 2-10 is a small, mostly unremarkable compact dwarf galaxy. Its estimated dynamical mass is about 1010 M⊙, only a few percent of our galaxy's mass, and its distance from us is about 30 million light years. It is irregular in shape and does not fit in any category of the standard Hubble sequence.The only respect in which Henize 2-10 has attracted attention – for several decades – before now is a........

Is Romantic Love a Western, Heterosexual Construct?

by The Neurocritic in The Neurocritic

ROMANTIC LOVE WAS INVENTED TO MANIPULATE WOMEN-Jenny Holzer, TruismsDoes romantic love manipulate women into providing free domestic labor and sexual favors for men? Some feminist views of romantic love [and the institution of marriage] portray it as controlling and oppressive (Burns, 2000):‘STOP HUMAN SACRIFICE. END MARRIAGE NOW.’ ‘IT STARTS WHEN YOU SINK IN HIS ARMS AND ENDS WITH YOUR ARMS IN HIS SINK.’ From a feminist perspective, romantic love was, and is, seen to obscure or disguis........ Read more »

Supply Chain Turbulence

by Jan Husdal in

The norm in supply chain management is that variability is detrimental to performance as it causes cost in the form of stock-outs, poor capacity utilisation, and costly buffers. This paper questions this approach and argues that in the light of increasing turbulence a different approach to supply chain management is needed. [ ... ]... Read more »

Language metaphors and time

by Stas Sajin in Raving Psychology

Pinker and Chomsky might not like Whorf’s theory, but it is essential to remember that Whorf came up with it when psycholinguistics was largely non-existent and when there was not a lot of data from which one could derive plausible hypotheses. Therefore, it is important to keep a non-judgmental attitude and give Whorf the proper credit for at least asking the question, “Does language influence thought?”.... Read more »

“The virus is ‘dead’. Long ‘live’ the virus.” – what does history say about how virology should develop in the future?

by Connor Bamford in The Rule of 6ix

In the modern world, we are continuously challenged by viral disease; well established pathogens such as the measles and mumps viruses alongside recently (re)-emerging viruses such as ebola-virus and even those viruses which we currently know little about (XMRV?) all represent a continuous threat to human health and well-being. Yet how can this be true when we have been developing anti-viral vaccines for half a decade – surely we should be good at it by now? And, is this idea that we c........ Read more »
