Whichever group of terrestrial invertebrates grabs your attention in Britain, it’s hard not to notice, and read about, changes in species‘ distribution with warming temperatures. Mainstream books (e.g. Smallshire & Walsh 2004) give suggestions for future vagrants and colonists to look out for, while even a cursory look at the topic gives any number of anecdotal references to invertebrates moving further north into or within Britain, including coastal species spreading inland. However, wh........ Read more »

As I have blogged before, obesity is the physical manifestation of positive caloric balance and trying to manage your (or your clients’) weight without understanding (or teaching your clients) calories is like trying to balance your bank account without understanding money.
Just imagine wanting to balance your bank account without any concept of how much money [...]... Read more »

Inflationary cosmology may be our best and most researched model for the universe’s basic mechanics, but as any physicist eager to offer his or her own theory for the cosmos’ origins will tell you, there’s little evidence of the inflation’s crucial moments. We know the universe seems to be expanding, and we know that an [...]... Read more »
This looks like the second step of a tangent and I want to get back to endocrine disruption, but here is another bit of data that supports the benefits of vegetable protein. Intake of vegetable protein is negatively correlated with waist circumference and BMI. In contrast, intake of animal protein is positively correlated with waist circumference and BMI, at least in Belgians. There are a lot of questions to raise with this including the possibility that people who eat less animal protein con........ Read more »

It is very unfortunate to have a leisurely activity end in a disaster. A recent case report by Inchingolo F et al. published in the Head and Face Medicine journal illustrates this. When you go for fishing, you may end up with more than what you would have bargained for; the catch may be your very own eye, or in this case, the eyelid.... Read more »
Science is about the physical reality. Scientists themselves can also think about things outside of physical reality but that is not science. So why is there a trickle of papers dealing with freewill? I ask this because I cannot find anything for freewill to be free-from other then the processes of matter and energy in [...]... Read more »

I’m a contrarian. Majority consensus makes me shudder. I just like rooting for underdogs*. Those undersea ridges at the boundaries of tectonic plates, spewing molten magma to form new crust are o’ so popular these days.

I was talking to a Reuters reporter the other day and learned of a new acupuncture study out of China, this one about amblyopia, or “lazy eye”. Amblyopia is a common and interesting visual problem.

If religion is a virus, then perhaps the spread of religion can be understood through the lens of evolutionary theory. Perhaps cultural evolution can be modelled using the same mathematical tools applied to genetic evolution.
Well, that's overly simplistic, of course - as anyone who's followed the 'meme' controversy over the years will know. In fact, the authors of the paper I'm writing up today - Michael Doebli and Iaroslav Ispolatov at the University of British Columbia - studiously avo........ Read more »

Clinical neuroscience conditions represent a heterogeneous group of conditions with varying contributions from genetic and environmental influences. It has been common to view some of these conditions under the disease model presumed to represent a specific pathophysiology, tissue pathology (i.e. Alzheimer’s disease, Huntington’s disease). Other conditions have been classified as representing primarily a disorder of behavior (i.e. anorexia nevosa, substance use disorders).The dis........ Read more »

It seems sensible and seductive to suggest that child abuse causes mental disorder and that mental disorder aggravates the risk for male suicide. However, contrary to what Mandelli et al.

... and what to do about it.
Decisions within a company are not made on pure rational grounds. Assuming that there is the will to make a rational decision, nevertheless limits in information gathering, computing capabilities and memory lead to irrational conclusions (bounded rationality).
So the goal must be to enhance rational decision making and for this end Kaufmann et al. (2009) developed a framework to combat irrationality.
The authors use case studies to analyze companie........ Read more »
