Role of Smads and WWP2 in potentially blocking some cancers

by Sally Church in Pharma Strategy Blog

“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 →...

For T. rex, Scavenging Was a Tough Gig

by Brian Switek in Dinosaur Tracking

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 »

Stand Up and Walk; Repeat Often

by Sara Klink in Promega Connections

As someone who regularly works at a computer both at work and at home, sedentary activity is a part of my daily life. Unfortunately, my desk is the standard kind that requires me to sit on a chair; I can only dream of the kind that has a treadmill to encourage movement as I work. [...]... Read more »

Need A Date? Take A Cue From The Birds

by Jason Goldman in The Thoughtful Animal

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 »

Talking about Love

by gameswithwords in Games with Words

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 »

Tip of the Week: iRefWeb + protein interaction curation

by Mary in OpenHelix

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!
And at the time we also mentioned their webinar was ........ Read more »

Brown Fat Helps Clear Triglycerides

by Arya M. Sharma in Dr. Sharma's Obesity Notes

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 »

Study Suggests New HIV Therapy

Human bodies are naturally equipped with elaborate defense mechanisms to squelch intruding microorganisms. But some viruses, like HIV, are able to slip under the immune system radar and set up permanent residence in a human host. Exactly how this feat … Continue reading →... Read more »

Choosing to either disgust your jurors or tick them off

by Rita Handrich in The Jury Room

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 [...]

The Saga of Landau-Gauge Propagators

Beauty-is-Good Stereotype in the Brain

by Psychothalamus in Psychothalamus

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........

Severity of Supply Chain Disruptions

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

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 »

Towards an artificial retina for color vision

by Michael Berger in nanowerk

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 »

How reliable is our memory for our own previous intentions

by BPS Research Digest in BPS Research Digest

Why did I buy this?
The fallibility of eye-witness memory is well documented. But what about people's memories of their own past intentions? This is an unexplored issue in memory research with real-life implications.

Consider the copyright infringement case in 2002, in which French composer Jacques Loussier sued Eminem, claiming that the track Kill You sampled beats from Loussier's work. Loussier further claimed that the success of the album was due in large part to the popularity of that spe........ Read more »

Psycasm - The Art of Character Creation

by Rift in Psycasm

I bought my girlfriend a Wii some time ago and before playing any game we spent 2 hours making Mii's of ourselves and all the people we know. A Mii - for those not in the a know - is your Wii avatar. It is associated with your personal stats on games such as WiiFit and WiiSport. Now Mii's are downright cartoony, but we tried to make them as lifelike as possible. After you're done it; (read more)

The Australia Antigen

by James Byrne in Disease Prone

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. So how god or bad is the situation really? The authors examined the accuracy of reporting between 1989 and 2009 by seven prominent US and UK newspapers:New York TimesWashington PostLos Angeles ........ Read more »
