Personality Traits and Political Attitude

by Dr Shock in Dr Shock MD PhD

The relationship between personality and political preferences is not the simple relation between conservatism and negative personality traits on the one hand and liberalism and positive personality traits on the other hand. Personality is understood as the combination of innate dispositions and personal experiences that guides behavior in a stable and predictive manner. Behavior is [...]

Bogs self-restore after reduction in power plant emissions

by Rob Goldstein in Conservation Maven

A new study in Estonia finds that reductions in power plant emissions can allow degraded bogs to naturally self-restore. Since the 1950s power plants in northeast Estonia have emitted thousands of tons of calcium-rich fly ash along with other atmospheric pollutants. These emissions have caused substantial pH increases in bogs and the addition of various chemicals leading to a widespread disappearance of Sphagnum mosses in favor of other plants adapted to neutral or alkaline soil conditions....

The View From the Veranda

by Michael A. Innes in The Complex Terrain Laboratory

Last week I gave a talk to some students at the School of Politics and International Studies (POLIS), at the University of Leeds. I've been an honorary Visiting Research Fellow with POLIS since April 2006, and it's a rare occasion when I'm actually on-site. In fact, this was only the second time, the first being a talk I gave in late 2007. Then, I was still a serving staff officer with NATO, and my talk was about a book I'd just published. This time, I was speaking as an acad........ Read more »

Insects use tools, but do they self-medicate?

by Cheshire in Cheshire

There’s a variety of things insects do that could rightly be considered tool use. Some ants will drop liquid in sand and carry the sand to the nest. Others will use their larvae to construct their leaf-houses…they essentially use their children as oversized glue-guns. If you live in Iowa, those big black wasps which you see flitting around on flowers (Sphecid wasps of the genus Sphex, which are understandably confused with Pompillids) will actually close their nests by pounding them........

Methuselah's Zoo

by Reason in Fight Aging!

Is the research community doing as much as it might to extract value from the diversity in life span amongst mammals? Certainly there are those scientist who would like to be engaged in a great deal more sequencing and biochemical deciphering of long-lived animals. But on the whole, I think that less is taking place in this area of study than might be. See this paper from a noted gerontologist, for example: As impressive as the accomplishments of modern molecular biologists have been in finding ........ Read more »

Steering drug discovery efforts away from the flatland

by Abhishek Tiwari in Fisheye Perspective

Does high-throughput synthetic practices have failed the drug discovery efforts by steering them toward greater unsaturation leading to more flat aromatic compounds those may not be better complement to the target proteins? Yes at least that's what Frank Lovering and others are suggesting. In a recent article published in Journal of Medicinal Chemistry Lovering et. al highlight lack of molecular complexity as key limitation of high-throughput parallel synthesis driven drug discovery efforts.

Glimpsing memory traces in real time

by Mo in Neurophilosophy

MEMORY is one of the biggest enduring mysteries of modern neuroscience, and has perhaps been researchered more intensively than any other aspect of brain function. The past few decades have yielded a great deal of knowledge about the cellular and molecular mechanisms of memory, and it is now widely believed that memories are formed as a result of biochemical changes which ultimately lead to the strengthening of connections between nerve cells.
However, it is also clear that memories are not enco........ Read more »

Stress Now, Mental Illness Later

by Neuropsych15 in The MacGuffin

Routinely, I enjoy crapping on the common biological explanations of various mental illnesses (e.g., monoamine hypothesis). However, this does not mean that I do not believe in the importance biology plays in the development of mental illness.To say that a specific mental illness is the result of a "chemical imbalance" or one "bad gene" is ridiculous. The problem with biological explanations of mental illness is that they neglect the psycho/social aspects of illness development (they are also po........ Read more »

I’ve got a lovely bunch of coconuts’ shells

by Zen Faulkes in NeuroDojo

Octopuses using coconut shells has been all over the web the last couple of days due to the publication today of a new paper by Finn and colleagues. The title is helping generate the attention: tool use.

This is a cool finding, but it is not as path-breaking as one might think.

First, the authors do note that there have been possible cases of tool use in invertebrates besides octopuses, but argue that other cases are too context-specific to be “real” tool use.

Second, this is not........ Read more »

Perceived age as a bio-marker of ageing

by sandygautam in The Mouse Trap

Do you look younger than your age? If so you have reasons to cheer! According to a new study as per Kaare et al, the perceived age is directly related to the actual ageing and inversely related to your telomere length.

It is well established that telomere length is a good indicator of ageing and also plays a crucial role in [...]Rating: 0.0/10 (0 votes cast)

An article just published to Nature has turned the world of evolutionary biology topsy-turvy!Or, so they’d like us to believe…The paper’s authors Chris Venditti, Andrew Meade and Mark Pagel have devised a new model that shows that evolution is not driven by natural selection or through the accumulative effects of random genetic drift. Rather than incremental and gradual change, their study suggests that the vast bulk of speciation results from rare stochastic events. They call this new the........ Read more »

Apoptosis, or programmed cell death, is regulated by the protein RanBPM (Atabakhsh et al. 2009, Molecular Cancer Research)

by Hannah Waters in Culturing Science – biology as relevant to us earthly beings

I have been fearful of molecular biology for most of my life.  This is partially because I so clearly defined myself as an ecologist that I partitioned molecules into “little biology” and out of my range.  But mostly it was a fear of what I considered unnatural.  Scientists who play around with chemicals and [...]...

New Dendro Dates and Provenances for Norwegian Ship Burials

by Martin Rundkvist in Aardvarchaeology

A new paper in the Norwegian journal Viking offers exciting news about two less-well-known ship burials from the Avaldsnes area in Rogaland on the country's west coast. Being poorly preserved, they have been difficult to date. Bonde & Stylegar now show with dendrochronology that these are the earliest dendro-dated ship burials in Norway!... Read more »

Downright sexy: The contrasting effect of vertical position on the perceived attractiveness of men and women

by BPS Research Digest in BPS Research Digest

If you're hoping to increase your online appeal to the opposite sex, you might want to consider where on the screen you place your photo. A study that's in press at Social Cognition has shown that women rate men's photos as more attractive when they're placed near the top of the screen. By contrast, men rate women's photos as more attractive when they're located near the bottom of the screen.Brian Meier and Sarah Dionne say their finding can be understood in terms of 'embodied' or 'grounded cogn........
