cognitive training doesn’t work (much, if at all)

by Tal Yarkoni in citation needed

There’s a beautiful paper in Nature this week by Adrian Owen and colleagues that provides what’s probably as close to definitive evidence as you can get in any single study that “brain training” programs don’t work. Or at least, to the extent that they do work, the effects are so weak they’re probably not worth [...]... Read more »

EZ-Tn5™ Transposomes help reveal virulence factors in Acinetobacter baumanii

by epibio in EpiCentral

Acinetobacter baumanii is a pathogenic bacterium that has been demonstrated to cause pneumonia, skin infections, and secondary meningitis, predominantly in a health-care facility setting. Its ability to form biofilms on inert surfaces is instrumental in creating reservoirs for opportunistic infection.... Read more »

Men, Capitulation to Distress, and GP Visits

by Ultimo167 in Strong Silent Types

Tedstone Doherty and Kartalova-O'Doherty (2010) call for a 'gender sensitive approach' to mental health policies, promotion, and prevention. They base this strategy on their findings that men 'do' help-seeking differently to women and that we need to take account of this gender split when planning services, et al. ... Read more »

The Five Points Then and Now: Ghosts of Tenements Past

by Krystal D'Costa in Anthropology in Practice

For such a small area, the Five Points really has a great deal of history connected to it. Walking through present day Chinatown, I was really struck by how various elements of the Five Points have persisted through time, and have managed to impart some of the old character into the neighborhood. The streets bustle with throngs of Asian residents, reminiscent of the earlier immigrant settlers who

The strange sex lives of bone-eating whaleworms

by Laelaps in Laelaps



For at least 30 million years, bone-eating worms have been making their homes in the bodies of decomposing whales on the seabottom, but the rotting cetacean carcasses are not just food sources for the polychaetes.

The term "worm" immediately conjures up images of the red, squiggly things which crawl all over the sidewalk after it rains, but this imagery does not fit the boneworms of the genus Osedax. These worms start off life as sexless larvae, and the timing of their arrival at a whale corp........ Read more »

The ecological threat that's bigger than climate change

by Paul Spraycar in Beyond Climate Change

The U.S. military reported this month that peak oil may be closer than we think. Despite this fact, the environmental impacts of an abrupt move away from oil have not been studied and are not well understood. In fact, according to a new paper published earlier this week in Conservation Biology, “the impact of peak oil will be far more immediate, certain, and perhaps larger than that of climate change, although peak oil has received far less scientific scrutiny, press, and funding than climate ........

Environmental factors like teacher quality and SES affect the full flowering of potential

by sandygautam in The Mouse Trap











Image via Wikipedia



This should be a no-brainer: in an era when increasingly words like ‘gene-environment interaction‘ are bandied around, it would be self evident that for full flowering of a prototypical trait, the genotype has to get the right environmental inputs. In absence of the right environmental conditions, the genetic differences may be masked More >Rating: 0.0/10 (0 votes cast)

Aggression spectrum disorders: The distinction between borderline personality disorder and psychopathy

by William Lu in The Quantum Lobe Chronicles

I recently read a fascinating book chapter written by William Arsenio titled Happy Victimization: Emotion Dysregulation in The Context of Instrumental, Proactive Aggression. Early in the chapter, the author discussed how according to a study, 4-year-old children tended to predict that a bully would feel happy after pushing around some poor chump on the playground, aka happy victimization (Arsenio & Kramer, 1992). However, at age 6, children who were probed further not only predicted that the bul........ Read more »

The Incredible Egg

Big big love in wetas?

by Zen Faulkes in NeuroDojo

Weta is not just the name of a special effects studio; it’s the common name for one very large insect (pictured) that is found in New Zealand. Like many animals on New Zealand, it’s under a bit of pressure from introduced mammals, so there are definitely conservation implications if you can understand the mating system of the animal.

Wetas make an interesting case study for studying body size and mating, because they are large for their lineage, and there’s also a big size difference be........ Read more »

Hello, stranger!

by Kevin Mitchell in Wiring the Brain

Faces are special.  Humans are innately interested in faces and so good at detecting them that we see them in clouds, shrouds, pieces of toast, tree-stumps, and even simple yellow circles with a couple of dots in them.  Even newborn infants (really, really newborn) are more interested in looking at faces than non-faces.  Not too surprisingly, this preference and ability extends to other species too.  Monkeys reared from birth with absolutely no visual exposure to either monkey or human faces........

Nearly 100% Out-of-Africa in the past 100,000 years

by Razib Khan in Gene Expression

Since I’ve been talking about the possibility of admixture with “archaics” (I’m starting to think the term is a bit too H. sapiens sapiens-centric, is the Neandertal genome turning out to have more ancestral alleles?)
