Language learning and height

by Ingrid Piller in Language on the Move

Are you tall enough to learn English? Have you ever reflected on the relationship between height and language learning? Well, I haven’t, and I’ve been in language teaching and learning for almost 20 years. So, I assume that most of … Continue reading →... Read more »

Tully’s Mystery Monster

by Laelaps in Laelaps

To say that paleontologists can’t make heads or tails of the Tully Monster would be untrue. The claw-tipped proboscis on the front end and the arrow-shaped rear fins at the posterior end can be easily identified in complete specimens. Beyond that, though, this 300 million year old invertebrate remains one of the most vexing fossil [...]... Read more »

Don't Assume that fMRI and MEG Will Give You Comparable Results

by Livia in Reading and Word Recognition Research

Accessibility: Intermediate/Advanced



There are three common methods of studying brain function in normal human populations: fMRI, MEG, an EEG. There is surprisingly little crosstalk between the techniques, mostly due to practical issues.For better...

by Persuasion Strategies in Persuasive Litigator

By: Dr. Kevin Boully “There is danger in all sports, anyone who plays them takes that risk for themselves.” -Mock Juror in recent sports litigation research Athletes choose to play sports that involve risk. Athletic teams, coaches and organizations are aware of the risk just like players So, how much personal responsibility does an individual athlete have for safely participating in his or her chosen sport? What must the player and the organization do to make sure all possible safeguards are........ Read more »

Psycasm - Magical Thinking: Voodoo, Prayer, Black Cats, and You

by Rift in Psycasm


Magical thinking is a funny term for a strange phenomenon. Broadly put it is the belief or expectation that our thoughts and actions will influence the future, others, or ourselves. I can only imagine it seems ridiculous for anyone reading this blog to consider the possibility of actually cursing someone, or placing a hex on their family. But I do imagine a certain percentage pray to a bearded man; (read more)

The scions of Shem?

by Razib Khan in Gene Expression

The media is reporting rather breathlessly a new find out of Arabia which seems to push much further back the presence of anatomically modern humans in this region (more accurately, the archaeology was so sparse that assessments of human habitation seem to have been made in a vacuum due to absence of evidence). Here is the major objection:
This idea is at odds with a proposal advanced by Richard Klein, a paleoanthropologist at Stanford University, that the emergence of some social or behavioral ........ Read more »

Sometimes, it does matter where you're from.

by TwoYaks in Gene Flow


One of the major thrusts of the research I've involved with in the last few years is in the world of "domestic introgression." Some times, when we move animals around, there will be a pre-existing wild form of that species. For reindeer transplanted to Alaska, it's the endemic caribou. Some mink farms are in areas that already have a wild mink population. And a dog is nothing, if not a very ... Read more »

Why HisH doesn't fire until it sees the whites of PRFAR's eyes

by Michael Clarkson in Conformational Flux

The enzyme imidazole glycerophosphate synthase (IGPS) can be a bit of a lump. If you bind just one substrate it doesn't do anything, even though its two active sites are separated by more than 30 Å. Only if the second substrate also binds does catalysis actually go at anything like a respectable rate. In a recent paper in Structure researchers from Yale report evidence that this change of pace results from a change in dynamics.

PDB code: 1GPW
IGPS consists o........ Read more »

Are there unintended health effects of genetic engineering?

by Anastasia Bodnar in Biofortified

Francis Thicke, agronomist and organic dairy farmer in Iowa, asks: Do you think there are unanswered questions about the health effects of GE foods? I have heard GE critiques frequently contend that there have been very few feeding trials on the health effects of GE foods, and that in the feeding trials that have been done, the results have raised questions about the safety of GE foods. For starters, what is your opinion Continue reading...... Read more »

Citrus call for backup to fight root-destroying pests

by Christie Wilcox in Observations of a Nerd

Citrus fruits are delicious. Their delicate balance of sweetness and tartness is a biochemical masterpiece. It's no wonder that they, of all nature's tasty options, are the highest value fruit crop in terms of international trade, with over 105 million tons produced annually. But these tempting produce face a persistant villain that seeks to destroy their roots; a menace known, cleverly, as the citrus root weevil.

The weevil's grubby larvae feed like maggots on the vital roots of citrus plants........ Read more »

Measuring Discrimination…with 9/11

by Rob Mitchum in ScienceLife

It is widely acknowledged that racial or ethnic discrimination can negatively affect a person’s health. But how can a scientist measure this impact? The treatment that a person encounters due to the color of their skin, their language, or their country of origin is likely a chronic stimulus, encountered over their entire life rather than [...]...

Typing vs. Longhand: Does it Affect Your Writing?

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

Do you write longhand or on a computer? How does this affect your writing process? I ran across a study with interesting results.

The researchers wanted to know how computer writing differed from pen and paper writing. They recruited university faculty and graduate students to write two reports, one on a computer and one on pen and paper. The participants were given background information for the reports (about a new system of bank charges and new company regulations) two days beforehand. ........ Read more »

Africa’s new, old gray wolf

by DeLene Beeland in Wild Muse

Africa has a new, old wolf. An animal that was previously called a subspecies of the golden jackal in Egypt has now been found to be a very rare relict species hiding in plain sight — an ancient gray wolf line still living today. Previously, it was thought that the Ethiopian wolf (Canis simensis) was [...]... Read more »

Genomic Imprinting V: DNA methylation and gene silencing

by Jon Wilkins in Lost in Transcription

So, we've already discussed the fact that genomic imprinting is mediated through epigenetic differences between the maternally and paternally inherited gene copies. That is, at an imprinted locus, the maternally inherited allele will have one pattern of epigenetic modifications, while the paternally inherited allele has a different pattern. These differences are first established in the male and female germ lines, when the alleles that will eventually become maternally and paternally derived are........ Read more »

A whole new RNA world

fMRI Scanning Salmon - Seriously.

by Neuroskeptic in Neuroskeptic

Back in 2009, a crack team of neuroscientists led by Craig Bennett (blog) famously put a dead fish into an MRI scanner and showed it some pictures.They found some blobs of activation - when they used an inappropriately lenient statistical method. Their point, of course, was to draw attention to the fact that you really shouldn't use that method for fMRI. You can read the whole paper here. The Atlantic Salmon who heroically volunteered for the study was no more than a prop. In fact, I believe he ........ Read more »
