“Ubiquitin-dependent mechanisms have emerged as essential regulatory elements controlling cellular levels of Smads and TGFβ-dependent biological outputs such as epithelial–mesenchymal transition (EMT). # In this study, we identify a HECT E3 ubiquitin ligase known as WWP2 (Full-length WWP2-FL), together with … Continue reading →...

Was Tyrannosaurus rex a fearsome hunter or a scavenger? The answer is “both.” In the early 1990s, the paleontologist Jack Horner popularized the idea that Tyrannosaurus fed entirely on carrion. The idea that this dinosaur—the “prize fighter of antiquity“—could not catch or kill other dinosaurs was shocking. Reporters and documentary-makers ate it up, but other [...]... Read more »

What's the best way for a lonely guy to get a date? If you're a Splendid Fairy-Wren (Malurus splendens, native to Australia), your best bet might be to frighten the object of your affection.
You've learned all about the birds and the bees; now it's time to learn from them.
Lots of research has shown that animals reduce their sexual behaviors when predators are around. After all, it isn't just potential mates who would see or hear an elaborate mating display, but also potential predators. The ........ Read more »

Much of my work is on verbs that describe emotion, called "psych verbs." The curious thing about psych verbs is that they come in two varieties, those that put the experiencer of the emotion in subject position (Mary likes/hates/fears John) and those that put the experiencer of the emotion in object position (Mary delights/angers/frightens John).
These verbs have caused a four-decades-long headache for theorists trying to explain how people know what should be the subject and what should be the........ Read more »

For this week’s tip of the week I’m going to introduce iRefWeb, a resource that provides thousands of data points on protein-protein interactions. If you follow this blog regularly, you may remember that we had a guest post from the iRefWeb team not too long ago. It was a nice overview of many of the important aspects of this tool, and I won’t go into those again here–you should check that out. Andrei knows those details quite well!

Regular readers may recall that recently brown adipose tissue, long thought to be only present in new born infants, is also present in varying amounts in human adults.
Furthermore, variations in the amount of brown adipose tissue, which is primarily a heat-generating organ, can contribute to substantial variations in daily total energy expenditure between individuals.
To produce [...]... Read more »

We know that if we want higher damage awards, we would rather have jurors mad than have them sad. But with all the focus on moral psychology (and particularly disgust) we thought it would make sense to look at whether having disgusted jurors is just as good as having angry jurors. Our hunch was that mad would [...]

Leo Tolstoy once said, “It is amazing how complete is the delusion that beauty is goodness.” And how complete is this delusion? In a recent study, Tsukiura & Cabeza (2011) provides an insight into this question by investigating the neural mechanism underlying the Beauty-is-Good stereotype. They were interested in the activity of the medial orbito frontal cortex (associated with positive stimuli, reward processing etc); the insular cortex (associated with negative stimuli, punishment processi........

We already know that supply chain disruptions can be quite costly, and have not only direct but also indirect effects (eg. on stock prices). So do all supply chain disruptions have the same effect on the focal company? Of course not, but what are the driving factors that influence the impact?
In their conceptual note Craighead et al. (2007) analyse the factors of the impact supply chain disruptions.
As many companies, the authors take the view that supply chain disruptions are inevitable ........ Read more »

One area of nanobiotechnology that will have a massive impact on improving the live of disabled people lies at the interface (literally) between artificial functional materials and living neuronal tissues. Neuroprosthetics is an area of neuroscience that uses artificial microdevices to replace the function of impaired nervous systems or sensory organs. Different biomedical devices implanted in the central nervous system, so-called neural interfaces, already have been developed to control motor d........ Read more »

I feel a little left out some times on the internet as many (but certainly not all) of my bloggy friends are English or American. So, just to fill you in, the 26th of January is Australia Day and it commemorates the landing of our first fleet in 1788 and the planting of the British flag in what was then known as New Holland and is now known as Sydney Cove, New South Wales, Australia. Most people celebrate the day with a public holiday, a beer or two, a barbi and the TripleJ Hottest 100.

An interesting analysis in Environmental Research Letters of the accuracy of media reporting of climate-related sea level rise. The premise: That the mass media associates sea level rise with climate change and reports on it frequently, yet the scientific community remains dubious of the media's accuracy.
