As the world economy dusts itself down and edges towards recovery, a provocative new paper claims that people with higher intelligence are more likely to think like economists. That is, they're more likely to be optimistic about the economy; to recognise the economic advantages of markets free from government interference, and the advantages of foreign trade and foreign workers; and to appreciate the economic benefits of achieving greater productivity with less man-power. The lead author is Brya........ Read more »

Continuing on from the basics of Phrenology, today we will discuss it's founder, Franz Joseph Gall.Phrenology: A Beginner's Guide Part 2 - The FounderAccording to Simpson (2005) Gall was a gifted German physician who developed the theory of functional localisation in the brain, and diagnosis by examination of cranial palpation, - Phrenology. Simpson (2005) states that Gall was born in 1758 in Tiefenbrunn and received his medical doctorate ni 1785 in Vienna. Simpson (2005) maintains that as a chi........ Read more »

(Note: this is a follow up to my previous post).In July 2005, JAMA began to require industry-supported studies to undergo independent statistical analysis. To see if this requirement affected the number of industry sponsored studies publicized in JAMA, Wager et al. (October 2010) looked for all randomized controlled trials (RCTs) published in JAMA from 1 July 2002 to 30 June 2008. They classified the trials according to their funding sources: Industry funded (IF), joint industry plus nonindustry........ Read more »

Disasters. The result: Damaged infrastructure. End result: Disrupted supply chains. But how do disasters really impact supply chains? While the damage done by windstorms and floods may be different from that of an earthquake, do they also impact supply chains differently, and does it even differ by industry or sector? Is it different upstream or downstream the supply chain? According to what Nesih Altay and Andres Ramirez wrote in their very recent article Impact of disasters on firms in differe........

A team of psychiatrists at the Naval Medical Center in Portsmouth, Virginia, USA have been taking a look at the religious beliefs of military folks who attended outpatient clinics, and they've turned up something rather interesting.
Well, in fact the main thing they found wasn't too surprising. It'll shock no-one to learn that these military patients were overwhelmingly Christian. In fact, 87% were Christian, 8% no religion, with a smattering of minority faiths. Only 73% of the US population in........ Read more »

One physiological problem (of many) that hibernating mammals face is the preservation of gametes during the winter months. During torpor, most animals do not continue spermatogenesis (the creation of new sperm) because it would require too much energy, but they also need sperm to be immediately available when they awake. This is because in many cases, the earliest born offspring have the best chance of surviving the following winter because they have more time to develop and build energy stores......... Read more »

The latest weapon in an oceanographer’s arsenal? Whales tagged with thermometers. A US team recently published a study into whether narwhals – a medium-sized Arctic whale – can venture where research ships struggle to go. The scientists led by Dr Kristin Laidre wanted to know if Baffin Bay, which lies between Canada and Greenland, warmed this decade. Researchers previously found west Greenland coast waters deeper than about 0.5km got hotter …... Read more »

The Kymograph was invented by Carl Ludwig in the 1840s. It's history is an interesting one, with its use being applied to various areas of science.van Bronswijk (2008) argues that the kymograph was the first recording device used to record and compare the influence of drug effects. Specifically, the kymograph enabled the study of the influence of drugs on a specific organ, which van Bronswijk (2008) argues enabled the development of Pharmacology as an independent science in it's own right.

A neutron star is made of neutrons, right? Astrophysicists ponder this question and forge theory after theory, but the only thing they conclude with certainty is that a neutron star by any other name would still be made of the densest form of matter know to exist in our Universe. Under certain conditions a star which has exhausted all of its fuel and is sufficiently massive will not be able to support its own weight with pressure support (as in a regular star) or with electron degeneracy support........

These days it's common practice for authors, peer-reviewers and even editors of medical journals to declare conflicts of interest, if those exist. However, the medical journal normally don't issue them same declarations. Journals publish regularly industry-supported papers reporting large clinical trials. Reprints of those trials are regularly bought by pharmaceutics companies and distributed to clinicians. The result is an increase of the journals' income as well as an increase in their presti........ Read more »

In Connie Willis' book, Bellwether, two researchers acquired a herd of sheep (they were studying fads). However, no sheep agreed to start a new fashion of pressing a button for food. What they needed was a bellwether, a fads-starting sheep. Cha et al. searched for bellwethers ('influentials') on Twitter. They sampled more than six million active users ('active' means 'more than ten tweets'). They used three measures of influence: followers (indegrees), retweets and mentions. The number of foll........ Read more »

The average person acquires most of hers or his health knowledge from the media. The question is, where do the media acquire that knowledge?Moriarty et al.
