Prenatal and neonatal blood mercury levels and autism

by Paul Whiteley in Questioning Answers

Acknowledging that some topics have the ability to furrow brows when it comes to autism research, mercury and autism is becoming something of a frequent talking point on this blog as a function of a whole slew of articles appearing in the peer-reviewed domain. If I were to [very tentatively] summarise the collected literature so far, it would be to say something like:Mosaic of mercury @ Wikipedia (i) there is quite a bit more research to be done on some sources of mercury being 'l........

Small Things, Big Problem: Microplastics Uptake in Shore Crabs

by Melissa Chernick in Science Storiented

Lately I've been gearing up for some nano-particle research, and so I've been doing a lot of reading about very small things. While perusing the literature, I came across a paper published online in Environmental Science and Technology that takes a look at microplastics.Let’s start with the Great Pacific Garbage Patch, a very good example of this type of marine pollution. This huge collection of marine debris in the North Pacific Ocean is created by an ocean gyre, a stable circular ocean curre........ Read more »

Spotted at last: “Homo economicus”?

by Neuroskeptic in Neuroskeptic_Discover

Are we selfish? Economists like to say that, to a first approximation, we are. In other words, that we tend to seek to maximize our own rewards, in a more or less rational manner. The trouble is that this theory (at least, a straightforward interpretation of it) doesn’t describe how people behave in many situations.

How our judgments about criminals are swayed by disgust, biological explanations and animalistic descriptions

by Christian Jarrett in BPS Research Digest

We expect of our jurors and judges calm, reasoned evaluation of the evidence. Of course we know the reality is rather different - prejudice and emotional reactions will always play their part. Now two new studies add insight into the ways people's legal judgements depart from cool objectivity.Beatrice Capestany and Lasana Harris focused on two main factors - the disgust level of a crime, and whether or not the perpetrators' personality was described in biological terms. Seventeen participants we........ Read more »

Some Bees Are Busier Than Others

by Elizabeth Preston in Inkfish

It may be time to leave “busy as a bee” with other dubious animal similes like “happy as a clam” and “drunk as a skunk.” That’s because some bees, it turns out, aren’t all that busy. A small group of hive members do the bulk of the foraging, while their sisters relax at home. But […]The post Some Bees Are Busier Than Others appeared first on Inkfish.... Read more »

Why job interviewers should focus on the candidates, not selling their organisation

by Christian Jarrett in BPS Research Digest

It’s hard to find the best person for the job through an interview. New research uncovers part of the problem: judging a candidate’s calibre becomes trickier when we’re also trying to sell them the benefits of joining the organisation.In an initial study, participants were asked to interview a person (another participant) who was acting as an applicant for a fictional position. Half the interviewers were told their priority was to get a good sense of the applicant, while the rest had to pr........ Read more »

Why the new paper by Christakis and Fowler on friendship makes me queasy

by neuroecology in Neuroecology

I am a neuroscientist, and as a neuroscientist I have a strange belief that most of who we are comes from our brains. My entire career is based around understanding behavior from this neural level which I feel to be fairly justifiable. So when I see paper looking at the genetics of behavior, I expect to see at […]... Read more »
