Anxiety and False Assurances First
Relief Third, Hopefully
Large rocks hurtle towards our heads. What happens? We duck. The process, however, is complex.
It involves answering two questions: what is that? and how do I behave? This anthropomorphic perspective is backwards and flawed. It suggests searching (for what, that and how) and then behaving.
The whole process (what, that and how) can be instinctive, like ducking the rock: body-as-it-was, object, body-as-it-is.1 Usual........ Read more »

Vitamin D is a hot topic lately, and many observational studies have linked it positively with a reduction in various disease risks. However, we should be careful not to tout it as a panacea without large controlled studies and a deeper understanding of how it regulates various endogenous processes.

New research out of the Oregon Health and Science University may explain the discrepancy between the theory and reality of dieting. They found that, at least in some of our closest relatives, cutting calories isn't enough to lose weight because the body compensates for the reduced intake by lowering activity levels.

I’ve written rather a lot about rates of forest loss around the world, including accumulated estimates of tropical forest loss and increasing fragmentation/loss in the boreal forest (see Bradshaw et al. 2009 Front Ecol Evol & Bradshaw et al. 2009 Trends Ecol Evol). For the tropics in particular, we used the index that an area [...]... Read more »
When it comes to chemistry, surfaces are the places to be. Where two phases meet, interesting stuff is bound to happen. One of the phase interactions that received increased attention during the last few years is the peculiar meeting of a liquid and a solid. One rather interesting phenomenon encountered here is the lotus effect, [...]... Read more »

Pull-down assays probe interactions between a protein of interest that is expressed as fusion protein (e.g., (e.g., bait) and the potential interacting partners (prey). In a pull-down assay one protein partner is expressed as a fusion protein (e.g., bait protein) in E. coli and then immobilized using an affinity ligand specific for the fusion tag. [...]...

Installment #2 in the mini-series on multilingual signage

Disease is a funny old thing. We're taught from very early on that disease agents are "bad" and that, by contrast, the infected are somehow poor and unfortunate victims of nasty evil bugs. This is clearly a cultural bias, wherein we project our own concerns about getting sick onto all other animals; there's no real reason to think that a bacterium or virus has any less right to be here or any ...

Say you're visiting Los Angeles and you have a sudden craving for Chinese food. Since you are only visiting, you might not be aware that nothing is open past, like, 10pm (not even coffee houses), but you get in your rental car and go driving around in search of your Chinese feast anyway. You try hitting up Panda Express, but no such luck. Of course they're closed. You try the neighborhood Chinese restaurant: closed as well. You get back in the car, and think to yourself "maybe the OTHER Panda Ex........ Read more »

The human brain likes balance. Not simply biological and physiological homeostasis that maintains the proper functioning of the brain, but emotional, social and psychological balance. Notably, the human brain dislikes inequality when it comes to money, and rejects it at all costs, according to new research in the journal Nature.

One of the arguments in the organic-can-feed-the-world oh-no-it-can’t ding dong is about the total yield of organic versus non-organic. Organic yields are generally lower. One reason might be that, with a few exceptions, mainstream commercial and public-good breeders do not regard organic agriculture as a market worth serving. The increase in yield of, say, [...]...

So Sci was scrounging around the internet for blog topics recently. Every time she does this, she is of course completely overwhelmed by the piles of cool and bloggable science out there (seriously, I've got like 20 topics for the next week, of course not all will make it). But she's also surprised to see some familiar faces. A lot of times it's a familiar face related to her field and the stuff she's been recently interested in (for example, Yavin Shaham just wrote an interesting editorial o........ Read more »
