4 Types of Internet Use among Children

by Dr Shock in Dr Shock MD PhD

Young people are high users of the Internet but we know very little about how they use the Internet, how they “are distributing their engagement across the various resources of the Internet”. This knowledge might be useful for learning and education.
Researchers collected data from a nationally representative face to face survey of young people (n=1069) [...]

The noisy brain

by Janet Kwasniak in Thoughts on thoughts

It is generally assumed, currently, that neural synchronization is the method of communication in networks of neurons involved in perception, cognition and action. In a recent paper Ward and others (citation below) have investigated the importance of stochastic resonance in this synchrony. So what is this thing called stochastic resonance?
You will eventually run into stochastic [...]... Read more »

Prehistoric Zoning

by teofilo in Gambler's House

When I was working at Chaco and would tell visitors that I was going to graduate school for city planning, most people would remark on what a difference that sounded like.  And, indeed, there are a lot of differences between my life when I was at Chaco and my life here at school in New [...]...

The ecology and geography of guppy speciation

by helikonios in The view from Helicon

And now for some more research blogging! Here’s a paper comparing the roles of geography and ecology in the early stages of speciation. I’m incredibly excited about this study because it begins to get around some of the major difficulties inherent in studying reinforcement and ecological speciation. But first let me back up and explain [...]... Read more »

Bad Metaphors Make for Bad Theories

by melodye in Child's Play

Imagine for a moment, that you have been thrown back into the Ellisonesque world of the 1980’s, with a delightful perm and even better trousers.  One fragile Monday morning, you are sitting innocently enough at your cubicle, when your boss comes to you with the summary of a report you have never read, on a [...]...

Circadian Genes and Metabolic Pathologies

by Allison in Dormivigilia

With my research projects dwindling in number, I’ve found some more time now to read the tens of Science journals lying around the lab. In a recent issue of Science, Joe Takahashi, an infamous chronobiologist known for inventing one of the first clock gene mutant mouse lines, and Joseph Bass discussed current research tying circadian [...]...

River otter latrines: so much more than just a pile of poop!

by Dr. Carin Bondar in Dr. Carin Bondar - Biologist With a Twist

Did you know that river otters come out of the water to do their business?  Indeed, instead of fouling their pristine river habitats, they crawl up onto the river banks when nature comes ‘a calling.  And they don’t just spread their scat around willly-nilly – they have specifically designated latrines.  Have a little respect for [...]...

DNA Reveals the Story of a Mysterious Group of Ancient Humans

by Dan Bailey in Smells Like Science

At the end of the last ice age modern humans were migrating out of Africa, Neanderthals roamed Europe, and new research has shown that a previously unknown population of ancient humans lived in Asia. All that remains of this mysterious group is a section of finger bone and a wisdom tooth. The group has been named the Denisovans after Denisova Cave in Siberia where the tooth and bone segment were found. A few months ago researchers completed an analysis of mitochondrial DNA from the finger bone a........ Read more »

(Merry) Christmas Disease

by James Byrne in Disease Prone

So I was feeling a little lazy and thought I should find a disease related to Christmas, that way it’d be topical and I’d look like a genius. Well maybe not a genius, as all I did was type “Christmas” and “disease” into google and it returned “Christmas disease”. Don’t worry though, the disease itself is pretty cool!

Contrary to popular belief Christmas disease is not limited to public drunkenness

Unfortunately for me my attempt at topical blogging reveals that Christmas di........ Read more »

Echinacea not as helpful as once thought?

by Science Exploiter in Science Exploits

To anyone shopping at a natural health food store, echinacea will certainly make its way to their 'to buy' list.  Along with the likes of St. John's Wort and fish oil, it has become a staple of the natural health movement.  While previous studies have shown a benefit to the supplement, recent research calls these claims into question.  The study, funded by the NIH and the National Center for Complimentary and Alternative Medicine, found an average duration of sickness of 7.03 days........

Every so often, Sci comes across a study that at first looks incredibly exciting…and then kind of becomes a bit of a let down. Not because it was a BAD study, mind, but because I want MORE. Thus was this study. So let’s talk about high fat diets, and let’s talk about coke. But mostly [...]... Read more »

Astronomy bottlenecks…

by Emma in we are all in the gutter

Guess what’s the largest hurdle impeding scientific progress in astronomy? Lack of money? Governmental disinterest? Nope, according to a paper published yesterday it’s our bad programming skills. Modern astronomers are much more likely to be found in front of a computer these days than behind a telescope. We spend our time analysing our data and [...]... Read more »

Am I lactose intolerant?

by Aaron Berdanier in Biological Posteriors

Lactose intolerance is a common condition; 70% of humans experience lactose intolerance worldwide, with abdominal discomfort, bloating, gas, and diarrhea coming from the consumption of dairy products. I have a hunch that I might be lactose intolerant, but I do not know, so I'm going to learn a little bit about lactose intolerance and do a study to assess the correlation between my eating habits and abdominal issues....

New place, new view, slow reactions and the origins of life

by The Curious Wavefunction in The Curious Wavefunction

I have been unable to blog for the past few days because I was busy moving to Chapel Hill for a postdoc at UNC Chapel Hill. I am very excited about this move and my upcoming research which is going to involve protein design and folding. Regular blogging will resume soon. Until then, happy holidays, and I will leave you with the following interesting paper published by a group from my new institution.One of the abiding puzzles in the origin of life is to explain how life arose in the relatively s........

Eugene Goldwasser & The Unforeseen Legacy of Epo

by Rob Mitchum in ScienceLife

When Eugene Goldwasser launched the project that would become his life’s work, he thought it would only take a matter of months. Since the early 20th century, biologists had predicted that a hormone they named erythropoietin must exist to promote the production of red blood cells when the body was running low. But in 1955, [...]... Read more »
