As usual, also for this year there has been the Festival delle Scienze (Festival of the Sciences) in Rome. This lasted for all the last week and ended this sunday. This is the chance to hear from leading scientists the status of forefront research. This year’s theme was “The End of the World – Instructions [...]... Read more »
Yesterday I came across this article, proclaiming to the world that "Saturn’s icy moon Rhea has an oxygen and carbon dioxide atmosphere that is very similar to Earth’s. Even better, the carbon dioxide suggests there’s life – and that possibly humans could breathe the air."
Say what? Ok. There's so much badness packed into those two lede sentences that I feel dirty just reprinting them here.... Read more »

In The Mass Extinction of Scientists Who Study Species, Dr. Craig McClain argues that we are loosing a fundamental unit of biological science – the Taxonomist. He’s right, of course. Taxonomy is a shrinking field. Entire phyla sit, unstudied, as the expertise necessary to understand them retires and expires. With few to train the [...]... Read more »

As in most countries, the population levels of obesity in Canada vary considerably from province to province (as they do within provinces). Although there are many “theories” on why this may be the case there has been little work done on trying to unravel the “explained” and “unexplained” regional variation based on a comparison of [...]...

Anthropogenic climate change has been hypothesized for centuries (discussed in Le Treut 2007) before the careful measurements of scientists in the mid-20th century. From 1833 to 1997, Stanhill (2001) calculated that the climate change science doubled every 11 years. The impact of carbon dioxide concentrations in the ocean was recognized early on with measurements and . . . → Read More: From the Editor’s Desk: The Grand Challenge of Ocean Acidification and Fisheries...

You could be forgiven for thinking that there’s no way you could get a useful brain scan of a fish.
First all, if you pay attention to brain scanning, you have probably heard a story about fish in fMRI machines that has become the stuff of scientific legend. The salmon in question being scanned for brain activity was deceased. Pushing up daisies. Size feet under. Joined the choir invisible. In a word, dead.
Yet a brain scan revealed statistically significant brain activity.

As the post on existentialism has been one of my most popular, I thought I would do something more on the subject of meaningfulness.

New research touts findings that conservatives have bigger amygdalas while liberals have bigger cingulate cortices. The bigger amygdala means conservatives could be driven by fear while the bigger cingulated cortex means liberals have more decision-making power. Hmmm. Is it possible that our politics are fixed at birth? Probably not. Neuroskeptic takes a look at the [...]

Oscar Wilde once claimed, “It is better to be beautiful than good, but it is better to be good than ugly.” This may be most true when meeting new people.

When we first learned about the cell cycle in high school, we learned about the stunning simplicity of certain proteins that cycle in order to promote progression through the cell cycle. In reality, that picture is quite complex, with many layers of regulation that affect those cycling proteins. A recent paper from the Nurse lab pares down all of that complexity to show us that the simplicity really has been there all along. The cell cycle is the sequence of events that leads to a cell&rsq........ Read more »

In many academic Emergency Departments, there are "off-service" or non-EM residents rotating in the department. They are sometimes invited to the EM residency conference series for the month. Often times though, they have too many departmental didactic events and obligations of their own that they don't have time to attend formal EM didactics.This is the perfect opportunity for an online didactic curriculum, which can be viewed at the residents' own time.

You are not alone ...
Have you ever had the feeling that everyone else seems so sorted, so at ease? You look about you and see friends chatting over lunch, people laughing on their mobiles, others escaping contentedly through novels or newspapers. According to Alexander Jordan and colleagues, most of us have such a tendency to underestimate other people's experience of negative emotion. In turn the researchers think this skewed perception perpetuates a collective delusion in which we all striv........ Read more »

One of the great things about the mass personal genomic revolution is that it allows people to have direct access to their own information. This is important for the more than 90% of the human population which has sketchy genealogical records. But even with genealogical records there are often omissions and biases in transmission of information. This is one reason that HAP, Dodecad, and Eurogenes BGA are so interesting: they combine what people already know with scien........ Read more »

In a recent study the conclusion about social networking sites and teens was that 93% of teens and young adults go online, compared to only 38% of adults over 65 years of age. It is surprising that 7% of 12-29 year olds still don’t use social networking sites. Twitter is the exception because it’s the [...]
