Trends and Outcomes of Adolescent Bariatric Surgery

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

Regular readers of these pages will probably be as depressed as I am to see the increasing need for discussing bariatric surgery in kids and adolescents.
Our evident failure to make any discernible headway in preventing childhood obesity has resulted in an increasing number of youth, who are now so severely obese that bariatric surgery often [...]... Read more »

Big Pterosaurs Really Did Fly: Interview with Mark Witton Part II

by Andrew Farke in The Open Source Paleontologist

A new paper in PLoS ONE, by Mark Witton and Mike Habib, re-evaluates claims that big pterosaurs were too big to fly. To make a long story short, multiple lines of evidence suggest that giants like Quetzalcoatlus really did take wing! One of my previous blog posts summarized the paper and featured the first part of an interview with senior author Mark Witton. That part of the interview focused on many of the scientific aspects of the research. Today, we'll highlight some of the other highlights. ........ Read more »

Pouches, pockets and sacks in the heads, necks and chests of mammals, part V: palatal (and other) pouches in camels and gazelles

by Darren Naish in Tetrapod Zoology

Everybody knows that camels are weird. As you'll know if you've been keeping an eye on SV-POW! lately, we've recently been quite taken with their necks. But it's not just camel's necks that are weird. Here, we embark on another look at the sometimes bizarre pouches, pockets and sacs present in certain mammals, most of which are outgrowths of the respiratory system.





Relatively little known is that (some) camels possess an inflatable diverticulum on the palate, termed the dhula, dulaa, gulah,........ Read more »

What do Women Want?

by Dr Shock in Dr Shock MD PhD


In short: women want dominant men as short term mates and prestigious men as long term mates. Dominant males being those who are ambitious, assertive and boss other people around, intimidating others. The kind of alpha males chasing desired women. The prestigious kind are those who achieve high social status through social networks (twitter?), making [...]

The flux of genes on the South Seas

by Razib Khan in Gene Expression


Huli Wigman from the Southern Highlands, Painting of Tahitian Women on the Beach by Paul Gauguin
Many demographic models utilized in genetics are rather simple. Yet the expansion and retreat of various demes in post-Ice Age Europe seems to be far more complex than had previously been assumed, though I suspect part of the rationale for [...]... Read more »

Prognostic Tool in Pediatric Oncological Hospice

by Brian McMichael, M.D. in Pallimed: a Hospice & Palliative Medicine Blog

In the December 1st issue of Pediatric Blood and Cancer is an article that presents the validation of a prognostic tool in pediatric hospice care. The study was produced by a team from the Hospital A.C. Camargo, a large cancer center in São Paulo, Brazil. Their overall survival rate in the treatment of pediatric cancers is just over 75%, roughly on par with those in the United States at approximately 80%. At this institution, a nurse-led, multidisciplinary palliative care team was developed in........ Read more »

Back pain: It ain’t what you do it’s ….?

by Lorimer Moseley in BodyInMind

Every now and then I stumble across a paper that evoked the reaction “I wish I’d though of that”. Such a paper recently turned up in the journal Rheumatology by Majid Artus and his colleagues at Keele University. They performed a systematic review that aimed to assess not the effectiveness of interventions but instead the [...]... Read more »

Dark Matter Fisticuffs I: The Backdrop

by sarah in One Small Step

On Thursday, two giants of astronomy met in the sleepy German city of Bonn to debate one of the basic tenets of our current cosmological vision: the existence of dark matter. In the blue corner was Simon White aka. the Reigning Champion, Director at the Max Planck Insitute for Astrophysics (MPA) in Garching, and figurehead of the concordance cosmology model we all know and live by. In the red corner, Pavel Kroupa aka. the Challenger, Professor at the Argelander Institute in Bonn and well-known e........ Read more »

Taking a closer look at health encounters for people with chronic pain

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

A theme of comments made by people I’ve seen clinically is that certain health care encounters they’ve had have not been especially helpful. Some people feel belittled, some patronised, some bamboozled, some dismissed – and yet in most surveys of health care satisfaction, the rating is pretty high (Jenkinson, Coulter, Bruster, Richards & Chandola, 2002). … Read more...

Bird song vs urban noise

by davesbrain in Dave Hubble's ecology spot

It's now well known that some birds can adapt their songs to different environments. For example, great tits (Parus major) have been shown to sing faster and at a higher pitch in urban areas (Slabbekoorn & den Boer-Visser 2006). This may be because urban noise, mostly from traffic, tends to be at a lower pitch and drowns out low-pitched birdsong. Also, the relative openness of city landscapes compared to woodland means that high-pitched songs are less likely to be lost in reflections in dense fo........ Read more »

When Organisms Really Shine... Bioluminescence Pt.1

by defectivebrayne in The Defective Brain

As near exclusive surface dwellers, we only see the sun-kissed top layers of the vast oceans of our planet. As we descend into the depths, the light from the sun dies away. And as we reach the bottom, we should be plunged into absolute blackness.
But we aren't. There are lights at the bottom of the ocean....... Read more »

Autism Gives You Biblical Superpowers

by Neuroskeptic in Neuroskeptic

We've all heard about autistic "savants" with amazing mathematical, memory or artistic abilities. But could autism give you the power to kill 1,000 men armed only with a donkey bone?Samson was the original Chuck Norris. Granted mighty strength by God so long as he didn't cut his hair or shave, Samson's first act of heroism was ripping a lion to shreds with his bear hands. Then he moved onto people. According to the Book of Judges:"And Samson said, With the jawbone of an ass, heaps upon heaps, wi........ Read more »

Warm blooded turtles?

by Iddo Friedberg in Byte Size Biology

If you entered this post to comment the error in the title, then I have one word for you. Gotcha! Yes, “warm blooded” animals are not, really, warm blooded. After all, a lizard in the baking sun has a core temperature higher than most mammals, but it is still called “cold blooded”.  So-called cold blooded [...]... Read more »

Einstein, tea leaves, meandering rivers, and beer

by Zoltan Sylvester in Hindered Settling

If you make your tea the old-fashioned way, ending up with a few tea leaves at the bottom of the teacup, and you start stirring the tea, you would expect the leaves to move outward, due to the push of the centrifugal force. Instead the leaves follow a spiral trajectory toward the center the cup. The physical processes that result in this 'tea leaf paradox' are essentially the same as the ones responsible for building point bars in meandering rivers. It turns out that the first scientist to make ........ Read more »

Saturday Review: The Inflammasome!

by Kevin Bonham in Food Matters

This week, I'm going to take a break from vaccines and do some innate immunity. Today's topic: the provocatively named "Inflammasome." This Nature Review from last month focused on inflammasomes and anti-viral immunity, but I think the inflammasome itself needs its own post.

A breakthrough in our understanding of the mechanisms that control the activation of inflammatory caspases came from the identification and characterization of the inflammasome, a large (~700 kDa) multiprotein complex that ........ Read more »
