Christian cancellation of the secular truce

by Tom Rees in Epiphenom

People living in the UK will have noticed that Christians have been getting noisier in recent years. More clamour for more state-funded faith schools, more litigations, and more complaints against perceived anti-Christian bias.Evidence of a popular religious revival? Or the death throes of a once-powerful ideology? A team from Erasmus University in the Netherlands has some answers.It seems that when Christianity is popular, Christians are content with the idea of a firewall separating Church and........

PCBs escape burial in aquatic sediments, infiltrate terrestrial food webs, and put birds at risk

by David Raikow in River Continua

While other issues of ecological concern, like climate change, receive popular attention, the problems that initially raised environmental awareness, like pollution, take a back seat. Yet these problems are not only still with us, they are spreading.... Read more »

Multiple Sclerosis and Irrational Exuberance

by PalMD in White Coat Underground

Multiple sclerosis (MS) is fascinating illness that can range from mild annoyance to debilitating nightmare. The frightening nature and unclear cause of the disease makes it a magnet for questionable medical therapies (i.e. quackery). A piece published last week in (surprise!) the Huffington Post helps fuel the fires of suspicion and paranoia while failing to shed any light on the future of MS research.

Multiple sclerosis is a disease of the nervous system. Its victims develop symptoms bas........ Read more »

Sex, Violence and The Male Warrior Hypothesis

by Shaheen Lakhan in Brain Blogger

Throughout the history of human civilization, wars have a common feature of being practiced primarily by males. This group aggression by males is a persistent trait of human behavior, seen across different continents among civilizations that have developed independent of each other.
Also, experimental evidence suggests that compared to females, male behavior and psychology is more [...]... Read more »

Holiday Weight Gain: Fact or Fiction?

by Travis Saunders, MSc in Obesity Panacea

Today I'd like to revisit an issue which we first reported on last January, and which unfortunately appears to be happening again this holiday season. Several of our colleagues attend a major Canadian fitness chain (I have decided not to post the name yet, but it shouldn't be too hard to guess) which has a poster of a chubby gingerbread man on the wall throughout the holidays (both in 2008 and again this year). Under the gingerbread man is a caption that reads "The average perso........ Read more »

Noisy and Bistable Gene Expression: Why Genes and Environment Aren't Everything

by Tim Sampson in The Times Microbial

Classically, a cell's phenotype was thought to be a product of its genetic background and its environment. All changes within a cell would be due to the cell's genetic capability to react to the environmental changes happening around them. However, as we begin looking more in depth at cell populations at the single cell level, we are finding that this paradigm isn't always true.

In this two part series, I want to examine how genetically identical cells in equal environments can........ Read more »

What a deal! Marine protected areas undercharging users...

by Rob Goldstein in Conservation Maven

When it comes to marine protected areas, managers are charging recreational use fees that are substantially less than what visitors would be willing to pay. Two studies have coincidentally come out recently in different journals addressing this counterintuitive phenomenon.

On the surface, charging too little might not seem like such a big deal. However, many marine protected areas are located in poor countries where the management of the park is largely funded by collected fees.

Radiation from medical imaging and cancer risk

by David Gorski in Science-Based Medicine

Science-based medicine consists of a balancing of risks and benefits for various interventions. This is sometimes a difficult topic for the lay public to understand, and sometimes physicians even forget it. My anecdotal experience suggests that probably surgeons are usually more aware of this basic fact because our interventions generally involve taking sharp objects to [...]... Read more »

Virtual Reality for Treatment of PTSD

by Dr Shock in Dr Shock MD PhD

Three fast track articles were recently published on CyberPsychology and Behavior about the treatment of PTSD with virtual reality exposure therapy. Exposure therapy is the most evidence based treatment for Post Traumatic Stress Disorder (PTSD). More than 18 studies have been published on the use of virtual reality exposure treatment for PTSD.

When Dec 25th Isn't Christmas Day

by Evil Monkey in Neurotopia

In celebration of the holiday season, Sci went looking for something seasonal. But referring constantly to things like how many calories we eat around this time (Sci is no exception) is really a downer. So this season, Sci decided to find out what would happen if you plug the word "christmas" into pubmed.

It turns out there are a lot of people named Christmas.

But Sci ALSO came across this study, which she found to be a really really cool phenomenon of SCIENCE! And so, as her holiday gift ........ Read more »

Keeping up with the Jones

by lynds in World of Ecology

Gardeners, ecologists and naturalists well know the frustration of keeping up with the latest up-to-date scientific names of the organisms they grow, study and appreciate. The plant list in my own research project is over 800 species long. I made sure that all their names were up to date with recent taxonomic revisions before I started my analysis, but now two years later I have found with horror that so many have since been changed!Admirers of Australian orchids are quite likely to be currently........

"Why we twitter: understanding Microblogging usage and Communities" by Java et al.

by David Brenes in Nobody's Papers

One year and a half ago I spent lot of times reading those foundational papers about Web Information Retrieval where first analysis of usage on search engines (main information retrieval systems for Web) were performed.

Those papers showed that the average user on the web search for information in a very different way, hardly describing their goals, visiting few alternatives and spending not much time.

Some months ago I was thinking about the quality and quantity of information that a search e........ Read more »
