…For some reason, you know you want to trust me.

by Rift in Psycasm

[Wherein our hero is AWOL, and you are stuck with me. Enjoy] Rift, your usual publisher is away having people talk about him in another language whilst he desperately tries to understand. Therefore today I will be posting about the simple topic of trust. So sit back, enjoy and trust that I will give you [...]... Read more »

Perfectionism as a Risk Factor for Anorexia Nervosa

by William Yates, M.D. in Brain Posts

Temperament is generally defined as innate early emotional and behavioral characteristics that precede puberty and adult development.  Felt to have significant genetic components, temperament is also potentially influenced by environmental factors. There are a variety of temperament domains that have received significant attention in childhood, adolescent and adult populations.  Some of the most commonly studied domains include:neuroticismharm avoidancenovelty seekingreward depend........

Studying Streptococcus - SGM series

by Lab Rat in Lab Rat

The fourth post now in the SGM series, and this one focuses on Streptococci. Streptococci are a genus of spherical Gram-positive bacteria containing both pathogenic and harmless strains, including the flesh-eating bacteria (which cause the delightfully named necrotizing fasciitis) as well as bacteria responsible for making swiss cheese. Commensally they are found on many parts of the human body, including the mouth, skin, intestine, and upper respiratory tract .Streptococcus - growth and divisi........ Read more »

Standard Cosmology Theory Is Confirmed By ACT For Smallest Scales In The Universe.

by Joseph Smidt in The Eternal Universe

It never ceases to amaze me how well standard cosmology theory fits the ever increasing amount of data with precision. The results just released from the Atacama Cosmology Telescope (ACT) confirm that, even on the smallest scales, the predictions of the Lambda CDM universe preceded by an epic of inflation are correct.  This study extracts data for L modes of The CMB between 500 and 10,000.  (For

Do the Health Benefits of Cycling Outweigh the Risks?

by Travis Saunders, MSc, CEP in Obesity Panacea

Regular readers of Obesity Panacea will know that I am a huge fan of active transportation, which entails commuting via active means (e.g. walking, cycling, or taking public transit rather than driving). But when I talk with my friends about the many health and societal benefits of active commuting by bicycle, they almost always bring up the fact that they value their lives too much to risk cycling on busy city streets. This is obviously not a trivial concern – here in Ottawa there were thre........ Read more »

Bone-eating worms and contorted creationist thinking

by Southern Fried Scientist in Southern Fried Science


I tend to avoid the creationist blogs. Every time I get sucked into that vortex of pseudoscience, I find the exact same debunked claims that were bunk when I was 12. There are better bloggers out there who have the energy and patience to systematically dissect the same tired old rubbish day after day, but I’m [...]... Read more »

Trial Run

It’s an old story: environmental protections laws enacted with the highest hopes end up entangled in lawsuits for years or even decades due to vague wording. But there may be a way to avoid the legal gridlock, argue two Australian scholars: Road test proposed rules in mock trials in “moot courts” before they get chiseled […] Read More »... Read more »

Chemistry of the Great Big Blue: Nutrients

by Bluegrass Blue Crab in Southern Fried Science


The Great Big Blue looks like it contains nothing but water and maybe a little salt, especially out in the open ocean. However, this kind of sparse environment is exactly where the chemistry matters the most – it’s a fine line between not enough, too much, and just right. Given this, there’s no distinct [...]...

How Plants Use Caterpillar Spit for Protection

by Steve W in Bridgehead Carbons

How do plants protect themselves from the bugs that chew on their leaves?  In the case of the wild tobacco Nicotiana attenuata, when tobacco hornworm (manduca sexta) caterpillars feed on the leaves a collection of molecules called Green Leaf Volatiles (GLV's) is released by the plant.  GLV's are released any time a leaf is damaged, but the interesting thing is that when the damage is done by chewing caterpillars, a different form of the GLV's are produced which attracts Big-Eyed Bugs (........

Disease detector

A while back my doctor did some routine tests for some vague symptoms I reported (all came back negative thankfully) and yes, I know you can get drugs to treat hypochondria. Anyway, of those tests was an ESR (erthythrocyte sedimentation rate, also known as sed rate). A test for patients with wide-ranging symptoms that may [...]... Read more »

Exoplanets at a discount

by sarah in One Small Step

Astronomers have many ways of spotting exoplanets round far away stars – but getting a direct look at them, especially with ground-based telescopes, remains a difficult job. With a planet emitting very little light of its own, and appearing to us essentially on top of the host star, its radiation is completely drowned in the [...]... Read more »

Pediatric Weight Management In Canada

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Around the world, management of childhood obesity is posing increasing challenges for already overburdened health care systems.
While prevention efforts may eventually halt or even reverse the obesity epidemic, for children already living with excess weight, prevention efforts are similar to locking the barn door after the horse has bolted - these kids need help now.
So [...]... Read more »

Genetic differences within European populations

by Razib Khan in Gene Expression

One of the more popular posts on this weblog (going by StumbleUpon and search engine referrers) focuses on genetic variation in Europe as a function of geography.

Assassination or accident?

by iayork in Mystery Rays from Outer Space

I have as much respect for viruses’ ability to manipulate their host as the next guy, and I’m probably more of a fan of viral immune evasion than that next guy.
