Interleaving
by Joshua Fisher in Text Savvy
Can we please talk about how we keep kids trapped for too long in counting number land? I've got this marvelous study to show you which might provides some good reasons to interleave different number systems throughout students' educations. It's this one.... Read more »

The science of stereotyping: Challenging the validity of ‘gaydar’
by Dr. Jekyll in Lunatic Laboratories
“Gaydar” — the purported ability to infer whether people are gay or straight based on their appearance — seemed to get a scientific boost from a 2008 study that concluded people could accurately guess someone’s sexual orientation based on photographs of their faces. In a new paper researchers at the University of Wisconsin-Madison challenge what they call “the gaydar myth.” William Cox, an assistant scientist in the Department of Psychology and the lead author, says gaydar isn’t ........

Vitamin D fortified mozzarella topped pizzas. Yum!
by Paul Whiteley in Questioning Answers
A slightly more light-hearted but nevertheless important post for you today as I bring to your attention the paper by Banaz Al-Khalidi and colleagues [1] and their conclusion that: "Vitamin D3 is safe and bioavailable from fortified mozzarella cheese baked on pizza."Adding vitamin D3 - cholecalciferol - to mozzarella cheese, researchers assessed what happened to serum levels of 25-hydroxyvitamin D in a high (28,000 international units, IU) and low (200 IU) dose group of "96 appare........

Common antidepressant may change brain
by Dr. Jekyll in Lunatic Laboratories
A commonly prescribed antidepressant may alter brain structures in depressed and non-depressed individuals in very different ways, according to new research. The study – conducted in nonhuman primates with brain structures and functions similar to those of humans – found that the antidepressant sertraline, a selective serotonin reuptake inhibitor (SSRI) marketed as Zoloft, significantly increased the volume of one brain region in depressed subjects but decreased the volume of two brain areas........

It's Easy to Be Fearless When You Have a Good Shell
by Elizabeth Preston in Inkfish
Aesop never penned a fable about a snail. If he had written about a certain freshwater mollusk, the moral might have been Boldness comes from a strong shell or maybe Careless snails get chomped. But because the snail and its variable shell are real, their lesson has more to do with the the weird workings of evolution.
Individual Radix balthica snails can have differently shaped shells. They also have varying "personalities," at least as far as you can measure such a thing in a mollusk......... Read more »

Everolimus for the treatment of lymphangioleiomyomatosis
by Danielle Stevenson in BHD Research Blog
mTOR is dysregulated in a range of tumour types and can be targeted with mTOR inhibitor treatments such as everolimus and sirolimus. Tuberous sclerosis complex (TSC) and sporadic lymphangioleiomyamatosis (LAM) result from mutations in TSC1 or TSC2 that disrupt mTOR signalling (Carsillo et al., 2000, Glasgow et al., 2010). The associated aberrant cell growth, survival and movement results in the formation of slow growing tumours in various tissues and pulmonary cyst formation with loss of pulmona........ Read more »

Reproducibility project: A front row seat
by Dan Mirman in Minding the Brain
A recent paper in Science reports the results of a large-scale effort to test reproducibility in psychological science. The results have caused much discussion (as well they should) in both general public and science forums. I thought I would offer my perspective as the lead author of one of the studies that was included in the reproducibility analysis. I had heard about the project even before being contacted to participate and one of the things that appealed to me about it was that they were t........ Read more »

Fuels and fungi: A love story
by Rosin Cerate in Rosin Cerate
Fuels and fungi have a long-standing and intricate relationship. Before we get into the juicy details, let's examine the players.Traditionally speaking, a fuel is any organic substance (e.g. wood, coal, and oil) containing lots of stored chemical energy within the bonds holding its atoms together. This energy can be released via combustion, which we harness to move cars forward and generate electricity.Fungi are a huge group of organisms largely describable in terms of what they lack: locomotion........
