Carin’s paper pick o’ the week, March 19, 2010:
Much of what we know about food web structure comes from work that focuses on negative interactions between trophic levels (e.g. predation and competition). However, facilitative (positive) interactions should not be ignored when it comes to elucidating the importance of food-web interactions. The work outlined in this [...]... Read more »

At almost every aquarium I have ever visited with a seahorse exhibit, the plaque in front of the tank says the same thing: in seahorses and their relatives, males, not females, carry the babies. It is always interesting to watch the reactions of visitors to this curious fact. Adult men, for instance, sometimes seem unsettled by the thought of male pregnancy, but the reproductive reversal among the fish is often seen as kinda cute ("How sweet. A fishy dad taking care of his kids!"). As shown........ Read more »

Footballers, particularly those who play at national or international levels, sometimes seem to have it all: celebrity, fitness, money and success. But rather than just supposing that this is the result of football's cultural status and importance, researchers have also suggested that it is the result of natural selection - not the survival of the fittest, as modern medicine and cultural systems ensure that in the Western world at least, most people have the chance to live, but perhaps the succe........

Just last week, two Hawaiian bird species from the island of Kaua’i and their respective habitats were put on the endangered species list along with a Hawaiian fly and 45 types of Hawaiian plants. However, while the action signifies movement from the Obama Administration toward protecting at-risk species and their habitats, the listing does not come a second too soon: Recent research shows U.S. birds, especially in Hawaii, are in great peril....

European bee populations are on the decline worldwide. Who cares? These bees are major pollinators of crops and therefore perform, for free, a vital ecological service worth about $U.S. 14 billion per year. Not to mention the many other species of non-crop flowering plants that reproduce with the help of insects like this.
The recent kind [...]... Read more »

That's right - contrary to what many religiously believe, it is the inability to grow more fat during times of energy surpluss, rather than the excess of fat which appears to directly contribute to the metabolic consequence often associated with obesity.
A recent article in the New Scientist shines some light on this issue;
Obesity kills, everyone knows that. But is it possible that we've been looking at the problem in the wrong way? It seems getting fatter may be part of........ Read more »

I've already mentioned one of the papers from the big 25th anniversary issue of JNABS. I've now read a handful of these papers, and they continue to be very interesting and a little bit annoying. Why are they annoying? Well, I like the review aspect of the papers, I don't like the "JNABS played X role in the development of X concept", because, really? Who the hell cares? This is a perfect ...

Between 84 million and 75 million years ago, near the end of the Cretaceous, part of the land now known as the Gobi Desert was host to a variety of raptors.

Early spring is a good time of year. Sci starts feeling a little more motivated, it's finally warm enough to feel comfortable running outside again (not that Sci ran inside, she was just very uncomfortable outside), and it's asparagus season!
When Sci was wee and her mother would try to feed her asparagus, Sci turned up her little nose at such nonsense. Why on earth would anyone eat something that was that green and looked like it had hair!?

Attention can be focused or it can be diffused. Attentional focus has been shown to be affected by mood or affect; with positive affect leading to a broadening of attentional focus; and negative affect, in general been shown to be associated with a narrowing of focus.

Measles infection in a brain cell nucleus
Having gone through Parts I, II, III, and IV of Measles week, let’s finish up by asking what this means for measles vaccine.
