Your Brain on Fast Food

by Jason Goldman in The Thoughtful Animal

Some kids more readily recognize Ronald McDonald than the President of the United States of America. Sad, right?

Check out this exchange, from the 2004 movie Super Size Me:

Morgan Spurlock: [to kids] I'm gonna show you some pictures and I want you to tell me who they are.
Children: OK.
Morgan Spurlock: [Showing a picture of George Washington] Who's that?
Child: George Washington?
Morgan Spurlock: Good. Who was he?
Children: He was the 4th president. He freed the slaves. He could never tell a l........ Read more »

Exercising In Front of Mirrors Will Bring You Down?

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

A couple of days ago I asked readers of my new FaceBook Page whether or not they preferred exercising in front of a mirror?
The response was mixed: for some definitely no mirrors, for some definitely yes, and for some the answer depends on the exercise (weights: yes; aerobic: no).
So what does research have to say [...]... Read more »

The volcano: an interesting scientific distraction.

by Andy Russell in Our Clouded Hills

I realise that the volcano that is currently erupting in Iceland has caused a lot of problems for a lot of people. However, if I can see one plus side it’s all the impromptu atmospheric science that is going on around it. For example, the first paper about the volcano, which is looking at the [...]...

BioFuel Cell Batteries May Power Future Implanted Devices

by Darcy Cowan in Skepticon

When I think about the future I sometimes indulge in fantasies that include “bionic” type implants. Not so much artificial muscles that will enhance strength (check this out) but devices that will expand our mental capabilities. Implants that give us greater memory, faster thought processes, the ability to download skills and knowledge directly into our [...]... Read more »

Water, Mars & Herschel (everyone else can, why can’t we?)

by Emma in we are all in the gutter

The first set of results from the Herschel Space Telescope have been flooding out over the past couple of weeks*, so it’s about time they got a mention here. Rather than rehashing one of the many press releases, I thought I’d focus on an interesting result that I doubt will get much attention – the [...]... Read more »

Short Cuts

by The Neurocritic in The Neurocritic

There is way too much to blog about these days. I can't decide among these 3 new papers:Sometimes, Categorical Statements about Prefrontal Neurons Are Just Wrong(1) Earl K. Miller (2007) in The Prefrontal Cortex: Categories, Concepts, and Cognitive Control (PDF):There was virtually no category effect across the ITC [inferior temporal cortex] population and no examples of neurons whose activity showed the sharp across-distinction/within-category generalization that is the behavioral signature of ........

EGF Pathway Found to Influence Nematode Longevity

by Reason in Fight Aging!

Researchers have uncovered what might be a new set of genes and protein mechanisms that influence healthy longevity: the epidermal growth factor or EGF pathway. The work was carried out in nematode worms, but the track record of such metabolic influences upon longevity carrying through into higher animals is pretty good so far. The epidermal growth factor (EGF) peptide induces cellular proliferation through the EGF receptor ... Inhibitors of the EGF receptor are being pursued as potential cancer........ Read more »

Book sales, frumpy readers, and mental rotation of book titles

by Grant Jacobs in Code for life

Last Friday I attended the 30th annual 24-hour book sale at the Regent Theatre, Dunedin, held to raise funds to maintain that glorious old place, all red seating with the lolly-decorated proscenium arch and pillars of an older era. Books are donated, collected and sorted by volunteers and “sold” to the punters.
It starts at noon Friday [...]... Read more »

How magic is your work?

by nuclear.kelly in Miss Atomic Bomb

If you're Dr. Kate Jones of the University of Tennessee in Knoxville, the answer is very.Inside of a nucleus, just like for the electrons in an atom, there are discrete energy levels into which the neutrons and protons can arrange themselves. In chemistry, this behavior - in electrons - leads to the periodic table: different elements behave in different ways chemically because of the number of electrons they have. More precisely, what matters is the number of electrons outside of a closed shell......... Read more »

Google Maps shows North Korea logging endangered tigers' protected forest

by Benno Hansen in Ecowar

This scandal has been reported on several websites: The sharp images from Google Earth clearly shows the North Korean communist dictatorship is logging forest areas in a UN national park. Not only does the megalomaniac Kim Jong-il seek to build a nuclear armament, impoverish his subdued people and occasionally sink South Korean ships – he's also cutting down trees in the fragile, ancient forest ...

quantum entanglement gets even weirder…

by Greg Fish in weird things

Richard Feyman once remarked “if you think you understand quantum mechanics, then you don’t understand quantum mechanics” and virtually every cutting edge experiment in the field seems to prove him right. Well, to be fair, physicists understand quite a bit about quantum mechanics but there are still quite a few mysteries to clarify including that of quantum entanglement. [...]... Read more »

A Little Bit More About Empathy

by Lindsay in Autist's Corner

Reproduces, with commentary, raw data (in the form of psychological test scores) from a study of emotional self-awareness and its effect on ability to empathize, as well as how both of those factors are affected by autism. Test scores are broken down by subscale, with special attention called to those scores that don't fit the commonly-accepted pattern of diminished empathic ability in autism... Read more »

Plague in 18th century Egypt

by Michelle Ziegler in Contagions

Egypt should hold a special place in historical plague research. Plague returned to Egypt on a regular basis for at least 1300 years. The first plague pandemic was first reported in Egypt in c. 541 and consistently reappeared through the 19th century. Alan Mikhail's study (1) on 18th century Ottoman Egypt brings up a number of questions on the nature of plague persistence and transmission. Mikhail argues that plague was a regular feature in an environmental pattern of flood, plague, famine ........ Read more »

how evolution shapes brains and microchips

by Greg Fish in weird things

What do brains and computer chips have in common? Not that much. Sure both use electricity, but in neurons the origin of electrical pulses is chemical while for computer chips it comes from electrical currents. Neurons are highly plastic, rearranging their connections to adapt to new information while computer chips are locked in their arrangement for their entire existence. But one thing they do share is the pattern of connections in their overall structure, [...]... Read more »
