Floral arrangement as a cognitive training tool for schizophrenia

by BPS Research Digest in BPS Research Digest

It's the hallucinations and delusions associated with schizophrenia that typically attract discussion and research. However, patients with a diagnosis of schizophrenia also exhibit deficits in memory and perception and, importantly, the severity of these is predictive of quality of life, social functioning and autonomy. How can these cognitive deficits be helped? Researchers have found some success with computer-based training but patient motivation can be problem. Now a team of researchers led ........ Read more »

What Is Sweeter than Cocaine?

by Scicurious in Neurotic Physiology

It’s been a while since Sci covered a good post on stimulants, and I’ve begun to feel the lack. I start to get the shakes, as it were. And this post covers something particularly interesting about cocaine, something VERY interesting about refined sugars, and even more interesting, this paper looks at some of the bugs [...]...

…We’re all Twits, here.

by Rift in Psycasm

For the most I’m a troglodyte. I hate facebook, I hate misspellings in SMS, and nothing makes me ROFL like a LOLcat. I do have a facebook, however, if only to keep up appearances and waste time during exam block. As of recently I have a Twitter account, too. Ordinarily I wouldn’t have signed up [...]...

Slow-burning Orangs

by zinjanthropus in A Primate of Modern Aspect

Lately, I’ve been a little stressed.  Long hours in the lab and moving into a new apartment have created the perfect storm for “treating myself” to restaurant food, served with a side of inactivity and sloth.  As I sit here at my desk, chowing down on crackers and reading the latest issue of the PNAS, [...]...

Your Love is My Drug

Review of a paper showing that the physiology of love addiction is comparable to drug addiction. Perhaps some of the same treatments used to treat drug abuse can be effective in curbing pathological love. ... Read more »

The Wednesday Post - Dying of a (literally) broken heart

by James Byrne in Disease Prone

How on Earth do you develop real heart failure due to depression? Well first we have to quickly do a course in cardiac physiology 101.

It has everything to do with how your heart works. Essentially, (and right now I predict that I shall be slaughtered in the comments but if you want to read a cardiac physiology blog, go find one :) ) electrical signals are generated in a patch of cells called the sinoatrial node (SA node) which is located in the right atrium....

One fish, two fish

The great count is nearing its end. Marine researchers have unveiled the first tidal wave of data from the Census of Marine Life, a decade-long effort to survey all sea life. The dozen papers, published by PLOS One, begin to detail the thousands of known species – from fish to flatworms — that live in […] Read More »... Read more »

The tragedy of the commons

by Bjørn Østman in Pleiotropy

While working on the last bits of my thesis, "Genetic and Ecological Models of Adaptive Evolution", I came upon Garrett Hardin's 1968 article [1], The Tragedy of the Commons (Wikipedia). It's really a great piece, which coined the term that is now an established and important notion in biology and elsewhere.... Read more »

On laws and sausages... and slavery

by Kris-Stella in Coffee Shop Philosophy

It is a well-known Bismarck quote: "Laws are like sausages. It's better not to see them being made." In the case of the British anti-slavery movement of the 19th century, this is true... and yet (just like sausage-making, I guess) so fascinating.In a great 1999 article on the development of a political coalition against slavery in late 18th and early 19th century Britain, Kaufmann and Pape discuss the origins and momentum of the anti-slavery movement. The article shows that even movements that i........ Read more »

New limit on neutrino mass… from cosmology, not particle physics

by Kelly Oakes in Basic Space

Physicists at University College London have found a new upper limit on the mass of a neutrino – one of the tightest constraints yet from either particle physics or cosmology. Neutrinos are elementary particles that travel close to the speed of light, but are very difficult to detect because they are not electrically charged. In [...]... Read more »

Placebos: All you never wanted to know (Part 2) - Theories

by Richard Morrisroe in DisgruntledPhD

Welcome back to this, the second post in my review of placebos. Now, to the fodder that makes us scientists, theories about the placebo. This is important as a good theory can both account for our data and predict new data, while also giving us something to falsify, which is apparently how science progresses. Steve Stewart Williams (all round good guy) reviewed the state of placebo theorising in 2004, and he specified that there are a number of criteria that a successful placebo theory should me........

Study: Dining Hall In the Dorm Means More Flab on the Freshmen

by David Berreby in Mind Matters

How do you persuade people to eat less and exercise more? We love to think it's a matter of getting them to see facts and make good decisions, because that implies that people are thoughtful and that their choices matter. But this paper, published online yesterday by the Journal of Adolescent Health, points to a more humble solution: Ignore people's thoughts and feelings, and just move the food further away.

Why don't we have more policies like that? I think it's because we........ Read more »

Experiments in Communication pt 1: Artificial Language Learning and Constructed Communication Systems

by Wintz in A Replicated Typo 2.0

Much of recent research in linguistics has involved the use of experimentation to directly test hypotheses by comparing and contrasting real-world data with that of laboratory results and computer simulations. In a previous post I looked at how humans, non-human primates, and even non-human animals are all capable of high-fidelity cultural transmission. Yet, to apply this . . . → Read More: Experiments in Communication pt 1: Artificial Language Learning and Constructed Communication Syste........ Read more »

ICN2010: One of the genetic roots of language points to self-learning in fruit flies

by Björn Brembs in

In 2001, an article was published in the journal Nature that a mutation in the forkhead-domain gene FOXP2 is involved in a hereditary speech and language disorder in a family in Great Britain. Today, many refer to FOXP2 colloquially as a 'language' gene and accumulating evidence suggests that FOXP2 is involved in language-like behavior in other animals, most prominently in song-learning in birds. Language as well as song learning in birds is an operant learning process, i.e., the birds........ Read more »

Why are there more Christian congregations where there is more crime?

by Tom Rees in Epiphenom

Take a middle-American US city – a fairly typical city with the usual mix of rich and poor, downtown and suburban, black and white. Indianapolis, let’s say. Which areas do you think would have the highest levels of crime?

Well, the poor areas of course. No surprises there. Downtown areas and those area with low population density are also at risk – probably a result of increased opportunities. Racially mixed areas have higher level of theft and burglary, although not violent crime. And t........ Read more »

Communicating environmental realities: framing and fiction

by Jeremy in Voltage Gate

I finally found the time yesterday evening to read through a few of the papers from the latest Frontiers in Ecology and the Environment, which is focused on science/environmental communication this time around.

The need for geophysical conservation

Double the mutualists, double the fun?

by Jeremy Yoder in Denim and Tweed

For all living things, information is critical to survival. Where's the best food source? Is there a predator nearby? Will this be a good place to build a nest? It probably shouldn't be surprising, then, that lots of animals do what humans do when faced with a host of hard-to-answer questions—they take their cues from their neighbors.

Red-backed shrikes place their nesting sites near where other shrike species have set up territories. Many bird species recognize each other's predator alarm ca........ Read more »
