State of the Field: Satellite tagging sharks

by WhySharksMatter in Southern Fried Science

Modern shark researchers have access to a variety of high-tech tools. Acoustic tags with noises specific to each individual shark signal a receiver (or network of receivers) every time the shark passes nearby. Some tags have three-dimensional accelerometers, allowing researchers to study the small scale movement patterns and behaviors of sharks. Others, which [...]... Read more »

Canada Releases World’s First Evidence-Based Sedentary Guidelines

by Travis Saunders, MSc, CEP in Obesity Panacea

Exciting news today – this morning the Canadian Society for Exercise Physiology (CSEP) released the world’s first evidence-based sedentary behaviour guidelines.  There have been some guidelines in the past, most notably for screen time, but they were essentially based on best-guesses more than any objective evidence.
These new guidelines are specifically for those aged 5-17, although there will hopefully be guidelines for both older and younger age-groups in the near ........ Read more »

Lying moths use the threat of getting eaten to help their sex lives

by Matt Soniak in

It’s a love story as old as time itself: boy Asian corn borer moth (Ostrinia furnacalis) meets girl Asian corn borer moth; girl secretes sex pheromones; boy goes through his courtship ritual, a little song-and-dance routine where he rubs his wings against his thorax to produce a soft, whispering sound. It’s a sweet little love [...]... Read more »

Humans draw the LINE at Gonorrhea. Not that it helps.

by Iddo Friedberg in Byte Size Biology

The day after Valentine’s Day. Ah! What better day in the year can we find to discuss gonorrhea? In the US alone 700,000 people are infected each year, and 5 million are infected worldwide. In most infected men gonorrhea causes urethral discharge and pain while urinating. The reason is that Neisseria gonhorrea have little hair-like structures called fimbriae. This makes them very sticky and they stick to the urethra’s walls. Then you get inflammation, urethritis and urinatio........ Read more »

Do allergies lower the risk of low and high grade Glioma?

by Sally Church in Pharma Strategy Blog

It’s not often that having multiple allergies is a good thing, but that certainly seems to be the case if a recent study published in Cancer, Epidemiology, Biomarkers and Prevention is accurate.  I was tempted to create a new category … Continue reading →

Ending the Immune War on Wheat

by Rob Mitchum in ScienceLife

The immune system is designed to protect the body against foreign invaders, neutralizing disease and infection. But organisms are all too happy to invite invasions several times a day through a seemingly innocuous act: eating. When food enters the digestive system, it has to be dealt with by the immune system just like everything else [...]... Read more »

To rock at video games, pick the red team

by Hel in Substantia Innominata

At the moment I play a lot to Team Fortress 2, a funny first-person-shooter where teams are red or blue. The aim is to defend your bases, to attack the enemies’ bases, to steal documents and so one. It is a really good game that I advice you. Well, I am not here to speak [...]... Read more »

This is Your Brain on Drugs

by Sanford- Burnham in Beaker

Cocaine produces its powerful high by stimulating “reward” signals in the brain, sending users back again and again for more. Cocaine gains this effect, in part, by stimulating a receptor called the metabotropic glutamate receptor 2 (mGluR2). Dr. Nicholas Cosford’s group is currently collaborating with Dr. Athina Markou at UC San Diego and Dr. P. [...]... Read more »

Primate vaccines: help you to help me?

The Tenth Anniversary of the Human Genome Sequence (in a nutshell)

by Katie Pratt in

Ten years ago today the first draft human genome sequence was published. Well, actually two sequences were published in that week. The first was from the Human Genome Project (HGP), a publicly funded international collaboration initialized in 1990, and was published in the journal Nature. The second was published in Science by Craig Venter’s company [...]... Read more »

Walking With Raptors

by Brian Switek in Dinosaur Tracking

A little more than a year ago, paleontologists working in Niger announced the discovery of Spinophorosaurus, a sauropod dinosaur with a wicked tail club. Its bones were not the only traces of dinosaurs to be found in the desert area. About three hundred feet from the exceptionally well preserved sauropod skeleton was a trackway containing [...]...

Why You Can't Cure a Plague of Olbermanns With An Infusion of O'Reillys

by David Berreby in Mind Matters

Do left-leaning social sciences need an influx of conservatives to open their collective minds? So argues Jon Haidt, but I wonder. As I read this study in this month's Journal of Risk Research, adding another ideology to social psychology would more likely lead to a lot of pointless yelling and a ...Read More

For lizards on white sands, evolution doesn't quite repeat itself, but it does rhyme

by Jeremy Yoder in Denim and Tweed

Check back tomorrow for an interview with this study's lead author, Erica Bree Rosenblum.

If life on Earth started over from scratch, would it eventually re-evolve the world we see today? This is the kind of question that makes for an entertaining argument over beers: "Well, without the Chicxulub impact, the dinosaurs wouldn't have gotten out of the way for mammals." "But dinosaurs were already turning into birds!" You might think that to resolve that argument, we'd need a second Earth and four........ Read more »

Do Nerve Genes Determine Excess Skin Fat?

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

As any clinician knows, patterns of fat deposition tend to vary greatly even in people with similar amounts of total body fat.
Not only are there the typical “male” and “female” patterns (commonly referred to as “apple” and “pear” shape) but there are also important differences in how much of excess fat is stored underneath the [...]... Read more »

The Andromeda Galaxy’s Globular Cluster System

by Christine Corbett Moran in Cosmic Rays

Globular Clusters (GCs) Globular clusters are groups of roughly spherical, densely packed stars. They are thought to have formed at the same time as most galaxies and the stars which make them up are some of the oldest known–thus GCs are an excellent probe of galaxy formation and evolution. They have a high central stellar [...]... Read more »

Influencing others by showing emotion: a new emotional ability?

by Alex Fradera in BPS Occupational Digest

Many workplaces recognise that besides more cognitive notions of intelligence – our capability to solve problems, use logic, process and judge factual information – they also need Emotional Intelligence (EI): the capability to recognise, make the most of and manage emotion. Now a new theoretical paper makes the case that we should be expanding this concept of EI to include the ability to influence others through emotional displays.EI currently focuses on spotting, dealing with and making sen........

Modeling and the scientific method

by Becky in It Takes 30

Last Friday’s Theory Lunch was interesting for a reason the speaker didn’t entirely intend.  In the preamble for his talk, Dan Beard wanted the audience to agree with him that the vision of the scientific method articulated by John R Platt — devise hypotheses, devise experiments to distinguish among them, perform said experiments, repeat (known as [...]...

Caught in the act: sneak preview of galaxy cluster that’s still forming
