English monkey gives itself a pedicure with self-made tools

by Ed Yong in Not Exactly Rocket Science

Animals use tools to get food, communicate with one another, defend themselves or even have a scratch. But in Chester Zoo, England, one monkey uses tools to give itself a pedicure.
Riccardo Pansini and Jan de Ruiter from Durham University watched a 18-year-old mandrill called JC clean his toenails out using small splinters. He made them himself, fashioning them from wood chips and twigs on the floor his enclosure, and honing them till they were small and sharp.
JC is the alpha male of the zoo’........ Read more »

Brown-Lipped Snails

by Africa Gomez in BugBlog

The Brown-lipped or Grove snail, Cepaea nemoralis has received a lot of attention by evolutionary biologists for more than a century, due to their strikingly variable shell colour - what is called colour polymorphism. In the decades of the middle of the last century it was a very popular research organism. The shiny shell can be yellow, pink or brown. Over each of these background colours there can be no bands, one band or five bands, and the bands can also be fused and be of variable width. The........ Read more »

Taking Bugs Out For a Spin

by Moselio Schaechter in Small Things Considered

by Linh Truong and Shabana Din

Microbes are the most robust of all life forms inhabiting our planet. Their ability to proliferate in extreme temperatures, pH, pressure, and radiation is well documented. They not only withstand but grow at physical extremes, which makes us wonder about the physical bounds for life not...... Read more »

The latest cult favorite in the sphere of human genetics is the microbiome, the genes of the bacterial species that live inside and upon the human body. Because bacterial cells outnumber human cells in an adult by approximately ten to one, and tens of thousands of different species make up the human ecosystem, studying this [...]... Read more »

The Princess on the Pea – Mechanisms of Chronic Pain

by Kim Kristiansen in Picture of Pain

Today we have a pretty good knowledge of the mechanisms behind chronic pain. This is a presentation of the basic understanding of how chronic pain starts, what causes it and why we most often are not able to see it on x-ray, MRI or other diagnostic procedures despite the fact that the patient are experiencing pain. We comes around allodynia, hyperalgesia, sensitization regulatory pathways and influence of sleep, depression and much more.

We also take a look on what could be wrong with “........ Read more »

On human health, interesting the public, and good scientific journalism...

by Heather in Escaping Anergy: The Immunology Research Blog

In addition to the "pulled from the scientific journal headlines" research discussed here, I thought it would be interesting to periodically showcase fascinating research that I read elsewhere. Awesome and interesting research about human health, disease and immunology is everywhere and sometimes, it's written about in a way that is clear, accurate and easy to understand! That last point is exactly what Escaping Anergy is all about: a place to see, interpret, discuss and most im........ Read more »

Shifting Stigmas: The Act of Crying in Public

by Krystal D'Costa in Anthropology in Practice

Jimmy Dugan firmly established that there’s no crying in baseball. But what about in public? In New York City, at some point or another you’re going to encounter a crying person—in fact, you could even be the crier. A few weeks ago, I boarded the subway for a short trip uptown. It was the middle [...]

The Saga on Fat Continues

Looking for that extra edge on the basketball court?  Want to increase your free throw percentage and gain an extra step in quickness?  Is it a new performance enhancing drug or training technique?  No, a new study suggests it may be as easy as spending a few extra hours in bed. Cheri Mah and colleagues from Stanford University and the University of California, San Francisco recently published their research on sleep and athletic performance in the journal Sleep.  They introd........

Does Neuronal Scarring Determine the Body Weight Set Point?

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

As regular readers are well aware, one of the major dilemmas in obesity management is the fact that virtually any attempt at weight loss is counteracted by complex mechanisms that aim to restore the body back to initial weight.
So far, no one has discovered a way to reverse or ‘reset’ this mechanism so that, once [...]... Read more »

Vaccine Confidence: Attitudes and Actions

by Scott Gavura in Science-Based Medicine

Few groups are more hazardous to public health than the anti-vaccine movement – because there’s a body count affiliated with their actions. When vaccination rates drop, communicable diseases re-emerge, and people suffer. While anti-vaccine sentiment will probably persist as long as vaccines are around, we’re fortunate that vaccination rates, on balance, remain very high. In [...]... Read more »

Men are as motivated by cute baby faces as women

by BPS Research Digest in BPS Research Digest

Cuteness as an evolutionary adaptation
Both Charles Darwin and Konrad Lorenz, the pioneering ethologist, wrote about the appeal of baby faces as a possible adaptive mechanism. They surmised that babies' perceived cuteness could be nature's way of ensuring the little terrors get looked after. Now a team led by Morten Kringelbach and Christine Parsons has shown that men are as motivated by baby faces as women. Kringelbach is the same researcher who a few years ago showed that looking at bab........ Read more »

more on auto metaphor recognition methods

by Chris in The Lousy Linguist

A quick follow-up to my previous post on automatic metaphor recognition. The paper Automatic Metaphor Recognition Based on Semantic Relation Patterns by Tang et al. challenges the dominant selectional preferences method by substituing their own Semantic Relations Patterns. They point out the problems with Selection Preferences (unfortunately I don't think they solved the problems with their own method, more on that in a bit).Again I'll give the Ling 101, computational linguistics for dummie........

Totally tubular! If Bill and Ted had an excellent adventure in the human body, you can be certain that they’d learn about the most excellent tube structures throughout the body. From the veins that carry our blood to the branching tubules in our lungs, tubes are very important structures. A recent paper looks at the role of adhesion proteins during tubule formation.During development, dramatic rearrangements of epithelial sheets results in the formation of branched tubules, as seen in kidne........

Marry far and breed tall strong sons

by Razib Khan in Gene Expression

The Pith: When it comes to the final outcome of a largely biologically specified trait like human height it looks as if it isn’t just the genes your parents give you that matters. Rather, the relationship of their genes also counts. The more dissimilar they are genetically, the taller you are likely to be (all things equal).
