Sergio Mora published a paper in the Journal of the Geological Society (here subscription is required for full text*). This was published back in December 2009, but it took on new (and rather unfortunate) significance in Haiti recently. It is really an excellent paper, he presented something similar as the keynote speaker at the 1st North American Landslide Conference in Vail, CO 2007. My summary doesn't do the paper justice, so I strongly suggest anyone reading this post find a copy of this art........ Read more »

We’ve known for a while that people with chronic back pain move differently. Normally when you are going to wave your arm or leg the deep spinal muscles kick in just beforehand, perhaps to provide stability. In back pain the activity of some of the deep back muscles is delayed in response to spine and [...]... Read more »

Active galaxies have gone by many names: active galactic nuclei, quasars, QSOs, Seyfert galaxies, radio galaxies. Astronomers used to think these were all distinct types of objects, unified by the observation of large amounts of energy emerging from a compact region at the centre of the galaxy. These days, despite a great variety in observational [...]... Read more »

Gamma-ray bursts (GRBs) are the most dramatic short-lived violent events observed in the universe. They are often described as releasing a quantity of energy, in less than a minute, that is at least as much as a star like the Sun releases in its entire 10 billion year lifetime. Since the first detection of a gamma-ray burst in 1967, the central question has been to determine the nature of the process or processes that can release so much energy so quickly.We've discussed gamma-ray burst several ........

Neuroskeptic readers will be familiar with the idea that too many people are being treated for mental illness. But not everyone agrees. Many people argue that common mental illnesses, such as depression, are undertreated. Take, for example, a paper just out in the esteemed Archives of General Psychiatry: Depression Care in the United States: Too Little for Too Few.The authors looked at the results of three large (total N=15,762) surveys designed to measure the prevalence of mental illness in Ame........

News this week that Pope John Paul II (that's the one just before the current one) used to spend his down-time whipping himself with a belt:As some members of his close entourage in Poland and in the Vatican were able to hear with their own ears, John Paul flagellated himself. In his armoire, amid all the vestments and hanging on a hanger, was a belt which he used as a whip and which he always brought to Castel GandolfoAnyone familiar with the Catholic faith will know that this kind of behaviour........

One of the most troubling features of the way North American cities have developed in the past quarter century is social isolation, as our own desires and the dynamics of the real estate business sort us into spaces exclusive to ever-narrower slices of humanity. Separate spaces for people of different incomes, places reserved exclusively for the elderly, spaces from which children are barred, and more.
There is much to worry about in this trend, but most worrisome of all is the social isolatio........ Read more »

William James, the influential American philosopher and psychologist of the late 1800's argued that remembering events reactivated motor and sensory brain regions involved during the original event. How right he was! Danker and Anderson have written an extensive review of the research literature looking at how this all happens, cleverly titled "The Ghosts of Brain States Past". Here is there abstract from the latest issue of Psychological Bulletin.There is growing evidence that the brain regions........ Read more »

What we know, in terms of herpes and HIV, and everybody can mostly agree upon:1) Co-infection with herpes simplex virus increases the risk of transmission of HIV, mostly from the decreased mucosal damage from herpes ulcers.2) Acyclovir, our preferred antiviral for herpes simplex, reduces HSV levels in blood.3) Acyclovir also has effects on HIV, with both in vitro and in vivo activity, either indirectly through HSV or directly on HIV replication itself.4) An exacerbation of HSV is associated with........

The data that Thoreau collected is meticulous enough to be considered a viable, useful data source by modern researchers. Thoreau's records of the area's wildlife have been carried on by others, providing us with over 150 years of data regarding the phenology of Northeast American flora; that is, life cycle events like fruiting or flowering days or migration and how these events are influenced by the seasons and the climate. Simply put, after 150 years of suffering the effects of distu........ Read more »

Most beauty research is done using static stimuli: static photographic images are used rather than, for example, dynamic video depictions. Since most real-world interactions with others do not involve static presentations, it is important to know how similar these two types of attractiveness ratings typically are.
