Hot housed Chinese schoolkids are getting ill from the stress

by Helen Jaques in In Sickness and In Health

A third of Chinese children experience high levels of school-related stress, and these kids are about five times more likely to have the physical symptoms of stress – that is, headache or abdominal pain – then their less frazzled peers.
Thanks to the combination of China’s recent economic growth – with the increased opportunities for upward [...]... Read more »

Personalized Medical Education

by Dr Shock in Dr Shock MD PhD

Medical Schools or medical education is mainly done in universities. Medical education in universities especially undergraduate education in North America as well as in Europe are full with very basic science such as chemistry, physics, but also laboratory branches such as biochemical education. I can still remember long afternoons using a pipette in endless rows [...]

Beewolf wasps culture their own antibiotics

by Michael Bok in Arthropoda

Humans have been aware of the antibiotic properties of some molds and plants for thousands of years. In classical times, fungal molds were used to treat infections. However, the true antibiotic renaissance began in 1928, when Alexander Fleming first isolated penicillin from the fungus, Penicillium notatum. Since then, penicillin and other powerful [...]...

Intelligence, Monogamy and Journalistic Licence

by Darcy Cowan in Skepticon

Last week news came out about a study linking intelligence with liberal attitudes and atheistic beliefs, oh and in men an increased tendency for monogamy. Today I read the NZ Herald’s short take on the study, a semi-chauvinistic piece pointing out how we evolved intelligent men can think our way to monogamy while those sexually [...]... Read more »

Superoxygenation: how to prevent alcohol’s nasty side-effects

by aimee in misc.ience

This is great news for all of us drinkers.  And, frankly, if I was just a little better at actual chemistry, how I’d make my first couple of fortunes*
And now I have the song ‘Tiny Bubbles‘ stuck, unfortunately, in my head. (When I first heard it, though it was an Aero jingle.  Possibly)

So yes.  To [...]

Fossil Snake Snacks on Sauropods

by Anne-Marie Hodge in Endless Forms

The patchy and elusive nature of the fossil record offers us limited glimpses as to what life was like during ancient times. Often, details of behavior and interspecific interactions are left open to interpretation and speculation. But occasionally, a sudden catastrophe caught ancient animals by surprise, killing and preserving them in a moment of activity. This is rather unfortunate at the time, but proves a boon to inquisitive hominds all these years later. This is exactly the case ........ Read more »

What if Bt saved human lives?

When I was in grad school, there was a lab in our department that studied intestinal parasitic roundworms.  Although this wasn’t related to what I was doing in any way—everyone who has been to grad school will know that you attend the department seminars for the donuts and/or pizza no matter what the topic is.  [...]...

Elucidating Sleep and Reward Centers

Elucidating Sleep and Reward Centers
March 1, 2010 - Author: Allison

It is rare for one to see an empirical article in a moderately-impactful journal, such as SLEEP, that solely reports about one case study (let alone have multiple affiliations……can we say out-sourcing/contracting the work?). I can overlook the extremely small sample size, however, because this study may help my lab elucidate a reciprocal relationship between sleep/wake and reward centers of the brain and relat........

Is this why atheists are, on average, more intelligent?

by Tom Rees in Epiphenom

There's a new paper out by Satoshi Kanazawa which is causing a bit of a stir. You might have seen something about it already - I'm a little behind the curve on this one, but on the plus side I have actually read the paper, unlike many other pundits!What's got people talking is the correlation between atheism and intelligence, although that isn't what the paper is actually about. It's already pretty well established that atheists tend, on average, to be more intelligent. This paper firms that fin........ Read more »

Official. Drinking alcohol leads to hangover

by Euan in Dr Euan Lawson| Doctor Writer

Hangovers offer rich pickings for complementary therapists. It’s the perfect fodder for alternative medicine. Give them an affliction almost completely characterised by a progressive recovery and they will be tumbling over themselves to offer ‘cures’. Staring bleary-eyed at the Sunday supplements the recommended homeopathic regime of nux vomica suddenly seem like a good idea. Rational [...]... Read more »

Decay Processes and Chordate Phylogeny

by Isabelle Winder in Going Ape

I have just read a Nature paper reporting some experimental work studying the pattern of decay in two soft-bodied species, Lampetra and Branchiostoma, which are thought to be the best proxies of the early chordates (chordates are the group of animals that includes the vertebrates and those invertebrates that are their closest relatives). The authors, Sansom et al. (2010), note that our understanding of the early evolution of the chordates is very sparse, in large part because the early chordates........ Read more »

What Attention Looks Like in the Human Brain

by Rob Mitchum in ScienceLife

The brain is essentially an electric organ. Other than slow chemical signals that pass between neurons, information is carried around the brain by electrical impulses, creating a noisy storm  that represents our senses, commands and thoughts. Experimentally, scientists can make some sense of this electric din by lowering an electrode into the brain and recording [...]... Read more »

On Software in Astronomy

by sarah in One Small Step

I’ve been giving some thought to software development in astronomy, which is a difficult topic. All astronomers agree that good data processing, and hence good software, is crucial to doing rigorous science. To interpret observational data, to translate electrons on a detector to scientific knowledge, requires a solid understanding of the instrument, the observing conditions, [...]... Read more »

Uncovering the "Chimpanzee Stone Age"

by Laelaps in Laelaps

An adult chimpanzee in Bossou, Guinea uses hammer and anvil stones to crack nuts as younger individuals look on. From Haslam et al., 2009.

Before 1859 the idea that humans lived alongside the mammoths, ground sloths, and saber-toothed cats of the not-too-distant past was almost heretical. Not only was there no irrefutable evidence that our species stretched so far back in time, but the very notion that we could have survived alongside such imposing Pleistocene mammals strained credulity.

New Sauropod From Dinosaur National Monument Gets a Name

Utah’s Dinosaur National Monument is best known for the exquisite collection of Jurassic-age fossils that have been discovered there since the beginning of the 20th century, but what is less well known is that more recent Cretaceous critters can be found there, too. When I visited the national park last summer I dropped by a [...]... Read more »

Evolving Molecular Machines: The Plant Edition

by Lab Rat in Lab Rat

Over at Thoughtomics, Lucas has a post up about the evolution of mitochondrial import systems. He starts by going back in time two billion years:"Life was well underway at the time, with proto-bacteria already populating the oceans for over hundreds of millions of years. One of the cells alive at the time, swallowed an alpha-proteobacterium. Something remarkable happened: the alpha-proteobacterium did not die but survived in the host cell. Over time, the host and symbiont became to be dependent ........ Read more »

Stars Born as Planets

by Invader Xan in Supernova Condensate

Planets are resilient things. They can survive a lot of punishment from their host stars, with some planets having survived being broiled and others even having survived being engulfed as their parent star swells into a red giant. Amazingly, the means by which planets form is no less hardy, for instance being formed in the debris left after a supernova as pulsar planets. So if the method for planet formation is so rugged, what would happen if you started out with an extremely massive star? Could........ Read more »
