Apparently my friends from Notre Dame are continuing to publish at a feverish rate, because I keep stumbling onto their papers. The latest is by Rothlisberger, Chadderton, McNulty and Lodge, and is all about aquatic invasive species (full cite is below), and I think this paper really throws into question the value of education and outreach.
There are a lot of big questions out there regarding ... Read more »

If you were a predator trying to design the perfect food source, you’d probably want something that was slow moving, reasonably large, and had no annoying hard bits that you couldn’t really eat. In other words, it would probably looks something like a nudibranch mollusk. Nudibranchs are also known as sea slugs or sea hares, and at first glance, they look like snack packs for predators.
Of course, nudibranchs don’t take this lightly. Rather than physical defenses, they put up chemical ones........ Read more »

Blythe Williams, Richard Kay, and Christopher Kirk have published a new article in the PNAS which does a very nice job in synthesizing some new fossils and new genetic data with current hypotheses for the origins of anthropoids, the group which includes old world monkeys (catarrhines), new world monkeys (platyrrhines) and apes (hominoids).

Cancer stories seem to make the news on a daily basis.

The sight of their own blood plays a key role in the comfort that some non-suicidal people find in deliberately cutting themselves. That's according to a new study by Catherine Glenn and David Klonsky that suggests it is those self-harmers who have more serious psychological problems who are more likely to say the sight of blood is important.There are plenty of anecdotal reports hinting at the importance of the sight and taste of blood to self-harmers, as well as references in popular music.

Anna O.'s Default Mode. Anna O. is the famous patient whose case was included in Studies on Hysteria by Josef Breuer and Sigmund Freud. Midsagittal brain image (PALS cortical surface atlas, Van Essen 2005) shows resting state functional connectivity in three cortical networks: (i) dorsal attention system (DAS, blue); (ii) the salience system (light green); and (iii) the default mode network (orange).

...chemical signals that switch tail enhancement into overdrive include those compounds released by other tadpoles as warning pheromones during predatory attack and those molecules discharged by the predator while digesting prey-tadpole tissues. So, in other words, a predator’s attack and digestion of a conspecific tad liberates chemicals into the water that are received by other tadpoles during development; as a result, resources are directed away from ‘normal’ growth processes and are d........

It also examines the role of PA in terms of weight management and weight loss. Hills et al.

Complicated cells are a weakness of mine, as you may have noticed. Ciliates satisfy this weakness really nicely, as they are utterly convoluted and insane in terms of both cell and genomic organisation. Ciliates are bizzare in almost every respect possible, from their sex lives to mitoses to nuclei on crack and extremely complicated morphology, and some are even loaded with epi- and endosymbionts, have parasitic bacteria inside their nuclei and there's even a couple anaerobes with reduced mitoch........

This is a long post, but hang on in there because it's worth it. There's a wonderful paper just out in Science that sheds new light on a mystery of human behaviour: why do people sometimes do good deeds even when they gain nothing from it.Some forms of altruism can be easily explained by evolution, but evolution can't explain why people are sometimes generous to completely anonymous strangers. This new study may have found a solution: it isn't something inherent to our nature, but rather somethi........ Read more »
