Psycasm - The Science of Marriage

by Rift in Psycasm

[Wherein our Hero pops a question - What's so great about Marriage?]I’m surrounded by marriage at the moment. In just the last three weeks I’ve had two cousins marry off (people my own age, I should add), and – most notably for LabSpaceCadets - Brian ‘Dear Overlord’ Kreuger has become happily married in the last day and a half.One thing I’ve noticed about Weddings is that it becom; (read more)

So, Homoeopathy has Benefits as a ... Talking Therapy?

by Maria Wolters in Speech and Science

Via Twitter, I noticed a study that claimed to show clinical benefits for Homoeopathy - not for the remedy, but for the consultation style. That aroused my interest. During three years of unexplained infertility, I saw quite a few CAM practitioners, a nutritionist, two herbalists (one Chinese, one Western), a Shiatsu therapist, an aromatherapist, a Structural Integration practitioner, and a woman who practiced Reiki. I was desperate and wanted to do something, anything, to become a m........ Read more »

Seek and ye shall find (friends online)

by Hadas Shema in Information Culture

Who makes new friends on social networks online? If we are going by the "rich get richer" assumption, we would expect to find that people who are already socially active will find even more friends on SNS. On the other hand, it's possible that those who have troubles forming offline relationships will socialize more on the Web (the "social compensation" model). The third possibility is the "seek and ye shall find" model: people who believe it's possible to create online friendships would be mor........ Read more »

The demon is out of the bottle

by Joerg Heber in All That Matters

Your desk at work, is it chaotic as mine, or clean and ordered? If the latter, I salute you, because it takes work to keep a desk tidy. Otherwise, chaos will soon reign. And while I admit that I should keep my desk cleaner (and no, I won’t share photos here), I have an excellent [...]... Read more »

Climate Change and the Importance of Maintenance Breeding

by Matt DiLeo in Biofortified

Variety IR8 is the original “Miracle rice” of the 1960s. This carefully-crafted variety has a stunted, semi-dwarf phenotype, which increases it’s harvest index (the proportion of grain biomass to total biomass), and allows it to resist lodging (falling over into the mud), even when heavily fertilized. As with wheat, the creation of dwarf varieties of rice played a major role in the enormous yield gains of the Green Revolution. But now it’s in Continue reading...... Read more »

Genes for autism or genes for connectivity?

by Jon Brock in Cracking the Enigma

Autism is a genetic disorder. We've known this ever since the 1970s when studies by Susan Folstein and Michael Rutter showed that identical twins  (who share the same random mix of genes from their parents) are much more likely to both be autistic than fraternal (non-identical) twins, who each have a different random mix of genes. These findings were incredibly important and fundamentally changed the way people think about autism. But they didn't tell us which genes cause aut........ Read more »

How to win elections by changing beliefs in God

by Tom Rees in Epiphenom

Aaron Kay a psychologist at the University of Waterloo in Ontario, Canada is interested in how people react when you make them feel like they're not in control of the situation they find themselves in.

He's previously shown that, if you disturb people's sense of control, then they tend to compensate by increasing their belief in a controlling god. In a separate study, he also showed that there's a similar relationship with attitudes to government. What seems to be happening is that, when people........ Read more »

Saturday Review: Oral Vaccines

by Kevin Bonham in Food Matters

Last week, I talked about strategies to improve vaccine efficacy and safety. Most of those strategies were in the context of standard, inject-into-your-arm vaccines, but what about totally new delivery methods? This week, there was a review in PLoS Pathogens of strategies for generating vaccines that you can swallow:

The Limits of Neuroplasticity

by Neuroskeptic in Neuroskeptic

Neuroplasticity is in.Books tell us about The Brain That Changes Itself or advise us on how to Train Your Mind, Change Your Brain.Now there's no doubt that the brain is plastic, able to rewire itself in response to damage or training, and that it's more so than was generally believed, say, 20 years ago. It's clearly an important and interesting field, but a little caution is warranted. Neuroplasticity can't fix everything.If the brain were infinitely plastic, brain damage would be no big deal.

Broken Taboo: A Major Journal Publishes Evidence of ESP

by David Berreby in Mind Matters

Psi is psychology's equivalent of the perpetual motion machine in physics. Claims in favor of telepathy, clairvoyance, premonitions or other extra-sensory perceptions were always considered the realm of looney-tunes who write to professors with no margins and lots of fanciful diagrams. Or worse ...Read More

Slow down = mow down?

by Alistair Dove in Deep Type Flow

Manatees in Florida are a battle hardened lot.  A large proportion of the sluggish sea cows have injuries from boat strikes, which is something of an occupational hazard when you live in the heavily trafficked coastal waterways of the sunshine state.  Indeed, lots of manatees have multiple scars from a lifetime of encounters with leisure craft, and boat strike is the biggest human cause of manatee deaths in that state.  The solution seems obvious, right?  Slow down! &nb........

Dutch Men Need Bigger Condoms

by Ultimo167 in Strong Silent Types

By surveying 2,350 men in five European countries, primarily by using the ‘Condom Fit and Feel Scale’, Dodge et al. (2010) came up with the conclusion that while most of these men had been happy with their prior condom experiences, there were some grumblings from the Dutch and the Slovenians. An interesting addition to the reasons behind 'why' some men choose not to engage in protected, safe sex, even though few of us could claim ‘ignorance’ on the importance of........ Read more »

Tetris Helps Prevent Unpleasant Memories of Gory Film in Happy People

by The Neurocritic in The Neurocritic

Most everything you've read about the Doctors Prescribing 'Tetris Therapy' study is wrong. That ridiculous headline, courtesy of "fair and balanced" Fox News, is the most egregious lie I could find [if you have other favorites, please leave links in the comments]. Press stories frequently distort research findings, but sometimes the authors themselves shoulder the most blame (Holmes et al., 2010). Misuse of the words "trauma" "flashback" "cognitive vaccine" and "PTSD" are at fault here.The exper........ Read more »

Pass the Twigs, Please – Toothwear Indicates the Variety of Chalicothere Diets

Chalicotheres were just plain weird. With horse-like heads, but bodies which appeared to be equal parts gorilla and giant ground sloth, these herbivorous mammals have stymied paleontologists for well over a century. Did they dig for roots and tubers with their massive claws, or did they use their long arms to bring leafy tree branches [...]... Read more »
