Evolution of Colour Terms: 8 Embodied Relationships

by Sean Roberts in A Replicated Typo 2.0

In a series of  posts, I’ve been discussing constraints on the evolution of colour terms.  In the last post, I discussed Perceptual Warping.  Here, a further adjustment to the assumptions about perceptual space is suggested.
The assumption that all perceptual spaces are the same may be unrealistic and may favour Universalism (see Levinson, 2000).  To begin with, . . . → Read More: Evolution of Colour Terms: 8 Embodied Relationships... Read more »

Synthetic ‘cradle’ boosts hope of stem cell therapies

by Wellcome Trust in Wellcome Trust Blog

Stem cells – with their famed ability to change into any type of cell – hold tremendous promise for medicine, but growing them is a challenging task. “For therapeutics, you need millions and millions of cells,” says Dr Krishanu Saha from the Whitehead Institute for Biomedical Research. “If we can make it easier for the cells [...]...

Narcissism on Facebook

by Dr Shock in Dr Shock MD PhD


In normal every day life with face to face contact the physical characteristics and knowledge about social background form the identity of your contact. It’s stable and three dimensional. You know that person, it’s therefor very difficult for the other to claim another identity or create impressions inconsistent with how you know him or her. [...]

Portrait of the artist as a Neanderthal

by Julien Riel-Salvatore in A Very Remote Period Indeed

In a recent paper, O. Moro Abadia and M.R. Gonzales Morales (2010) argue that an important component of the 'multiple species model' (MSM) that sees Neanderthals as having essentially 'modern' behavioral capacities and that originated in the late 90's is based not so much on new discoveries as it is on new ways of looking at the archaeological record. Specifically, they make the case that part of... Read more »

The dark side of photonics

by Joerg Heber in All That Matters

Photonics is all about light. Processing of light for applications ranging from holograms and displays to optical telecommunications. Thanks to a better theoretical understanding and to advances in fabrication technology, photonic devices and gadgets have become increasingly versatile and powerful.

But photonics also has a dark side. In many light-processing devices and structures there are dark modes — oscillations of the light wave that while not forbidden cannot be directly excited by a ........ Read more »

Rats Pee During the Night. A Surprise? Not Really

by Allison in Dormivigilia

Researchers have behaviorally confirmed an entrained rhythm of urination in the rat. Though this information is consistent with the recent shift in funding focus in circadian research (i.e. funding crutches), this is an example of a study that doesn't take advantage of advanced neuroscience techniques or at least attempts to elucidate the mechanisms. I mean, gosh, it was published in PLoS.... Read more »

Supply Chain Risk: Culture Shock

by Jan Husdal in husdal.com

Is culture shock the reason why so many global and cross-culture business relationships fail? When it comes to Western buyers and Chinese suppliers this may very well be the case, and while issues related to product quality or supplier reliability may seem as the obvious cause externally, cultural differences may be the root cause internally.

Life History theory and eight stage evo-devo model

by sandygautam in The Mouse Trap

Image via Wikipedia I’ve touched upon life history theory earlier, in an oblique fashion, while discussing evolutionary perspectives on personality. Life History theory posits that an individual’s life efforts can be subsumed under two headings- somatic life efforts and reproductive life efforts. The latter relates to selection due to being able to successfully replicate one-self;Rating: 0.0/10 (0 votes cast)... Read more »

Learning without thinking

by Carl in The motor chauvinist

Scratching around on the internet this afternoon on my first day back from holiday, I was kind of reluctant to dive straight back into taking papers apart. After all, I have spent the majority of the last three weeks drinking beer and eating pies in the UK, and the increase in my waistline has most likely been mirrored by the decrease in my critical faculties (as happens when you spend time away from the cutting edge). However, I ran across a really cool little article that reminded me just why ........ Read more »

High Excitement in Review: "Quantum information with Rydberg atoms"

by Chad Orzel in Uncertain Principles

I'm a big fan of review articles. For those not in academic science, "review article" means a long (tens of pages) paper collecting together the important results of some field of science, and presenting an overview of the whole thing. These vary somewhat in just how specific they are-- some deal with both experiment and theory, others just theoretical approaches-- and some are more readable than others, but typically, they're written in a way that somebody from outside the field can understand.........

How Language Affects Thought -- plus book giveaway!

by Livia Blackburne in A Brain Scientist's Take on Writing

I recently read Dreaming in Hindi, Katherine Russell Rich’s memoir of her year in India learning Hindi. Rich intersperses quirky anecdotes of learning and culture shock with scientific insights about learning a second language. I was excited see her mention two of my favorite studies on language and thought.

Psychologists and philosophers have long debated whether language shapes the way we think. While the most drastic viewpoint – that thought can’t exist without language -- has falle........ Read more »

Neuroscience of Murder and Aggression: Part 1

by William Yates, M.D. in Brain Posts

I have been interested in the genetics and environmental factors involved in aggression since working with Dr. Remi Cadoret at the University of Iowa in the 1990s.  We published an early study in adoptees that found an interaction between a biological background of antisocial personality and an adverse childhood environment in an additive effect in adoptee agression.  Adoptees with a biological relative with antisocial personality (usually fathers) were more aggressive when there were ........

In the news this month: pulsar irregularities

by Megan in Rigel

After massive stars like explode, the object left behind is thought to be either a or a black hole, depending on the final mass of the progenitor star. are neutron stars that have strong magnetic fields and behave somewhat like cosmic lighthouses, projecting beams of radio emission into space as they spin. Studying the pulses of radiation as the beams sweep past the Earth can provide valuable information on the physics of these extreme objects, allowing astronomers to probe physics under cond........
