Can the Tiger-Mom Approach Explain the Math Learning Gap Between America and China?

by Zijing He in ionpsych

Educators have long been concerned about the math learning gap between America and China: children in China and other East Asian countries outperform their American peers on various math tasks (e.g., counting, arithmetic, algebra, & geometry). To maintain America’s national … Continue reading →... Read more »

Alien Babies: To'au in He'eia Mangroves

by Megsie Siple in Fishpond Fever

While I was seining with the LAIP interns this past summer, we came across some interesting fish living near the mangroves. While some of the fish and nearly all the invertebrates we've seen are species that may spend their entire lives in the pond (the half-spotted goby, for example, or Podopthalmus vigil, the Hawai'ian swimming crab), others are transient. Many Hawai'ian fishponds are strategically placed at the mouths of streams because highly productive, protected estuaries ar........ Read more »

Insights into the pathogenesis of the Spanish Flu

by Michelle Ziegler in Contagions

One of the enduring mysteries of influenza is why the 1918 H1N1 influenza, better known as the Spanish Flu, was so unusually deadly. The 2009 H1N1 influenza was certainly capable of creating a pandemic but was not nearly as deadly. Granted most of the fatalities in 1918 had bacterial pneumonia that could probably have been [...]... Read more »

Mapping fitness: protein display, fitness, and Seattle

by Steve Matheson in The Panda's Thumb

A couple of months ago we started looking at the concept of fitness landscapes and at some new papers that have significantly expanded our knowledge of the maps of these hypothetical spaces. Recall that a fitness landscape, basically speaking, is a representation of the relative fitness of a biological entity, mapped with respect to some measure of genetic change or diversity. The entity in question could be a protein or an organism or a population,...... Read more »

by Stuart Farrimond in Dr Stu's Science Blog

I’m starting to get concerned. My wife has just started looking for her next handbag, and she has expensive tastes…

The Fourth Kind | a frank discussion and review

by Michael Lombardi in a New Life in the Sea


This weekend was an extra-terrestrial movie double header...but not of the District 9 type. Rather, despite the 'fiction' label on the DVD box, I took a deeper look at the realities of the paranormal and prophecy. This discussion will span the next several posts here on 'a New Life'.

The first film was 'The Fourth Kind'. Call me what you will, but I watched it late one night by myself, and it scared the bejeezums out of me.

This film portrays a series of psycho paranormal events&nbs........ Read more »

Egypt Week – Oxytocin and Ethnocentrism

by Jon Wilkins in Lost in Transcription

So, as we approach the end of Egypt Week, we are going to talk about recent paper in PNAS. The researchers examined the effects of oxytocin on the extent to which people exhibit in-group favoritism. They use ethnic markers to indicate in-group versus out-group membership. In this study, which was performed in the Netherlands, the in-group was Dutch and out-groups were German or Arab.

Here's the bottom line: subjects who were given oxytocin were more likely to favor in-group members relative to........ Read more »

Psycasm - It's like a blog in your ears

by Rift in Psycasm


So I've been a bit snowed under lately. As I mentioned recently, we've had some pretty big floods in my part of the world, and as a result all my summer semester workload has backed-up into one ugly pile of responsibility.And so my blogging has been a bit light on while I tackle these assignments and exams. Fear not, as soon as I get the chance I fully intend to look into what the litera; (read more)

Flooding and disease

by James Byrne in Disease Prone


I’m not sure what the coverage has been like overseas but most of the east coast of Australia has been hit pretty hard. First there were biggest floods Australia has seen for a VERY long time that started in Queensland and continue to affect the east cost of Australia. Then, instead of letting Queensland off the hook for a few weeks nature hit the coast with a cyclone THE SIZE OF THE U.S.A. that might move so far inland that it could dump rain into my state, which is a desert, halfway across ........

Hidden in plain sight: discovering cryptic vesper bats in the European biota

by Darren Naish in Tetrapod Zoology

In terms of its zoological diversity, Europe is the best known continent on the planet. Indeed it's generally assumed that just about all of Europe's macrofauna has, by now, been discovered. While that's mostly true, it seems that at least a few extremely similar species - so called 'cryptic species' - have been missed, mostly because they're extremely similar to their close relatives.





Here, I want to look briefly at new discoveries made concerning the diversity of European microbats [compo........ Read more »

Casual sex is not so bad after all

by Tom Rees in Epiphenom



Some women from Mars
A while ago I read a paper arguing that religion 'protected' teens against sex. It was your usual analysis - finding that religious teens are less likely to have sex outside of marriage - but the tacit presumption intrigued me. Is sex really that harmful?

Well, no one study is going to answer that, but here's one from Jesse Owen and colleagues at the University of Louisville helps shed some light on it.

Their study has the advantage over most in this field in that it's l........ Read more »

Touching Death

by Eric Michael Johnson in The Primate Diaries in Exile

The latest stop in the #PDEx tour is being hosted by The Prancing Papio:There is something intensely animal about our relationship with the dead. As an atheist I don’t feel particular reverence or awe at the site of a cadaver. It mostly just creeps me out. But even religious believers, those who should be comfortable with the idea that a dead body retains no trace of the person they once knew, also seem to have trouble letting go of what St. Paul called “confidence in the flesh.” In funera........
