How well can we communicate emotions purely through touch?

by BPS Research Digest in BPS Research Digest

Romantic couples outperformed pairs of strangers
Whether it's a raised eyebrow or curl of the lip, we usually think of emotions as conveyed through facial expressions and body language. Science too has focused on these forms of emotional communication, finding that there's a high degree of consistency across cultures. It's only in the last few years that psychologists have looked at whether and how the emotions can be communicated purely through touch.

A 2006 study by Matthew Hertenstein demo........ Read more »

Neanderthals and ornaments, birds of a feather?

by Julien Riel-Salvatore in A Very Remote Period Indeed

© Mauro Cutrona.
M. Peresani and colleagues (2011) report on the discovery of cut-marked bird bones from the latest Mousterian levels at Grotta di Fumane, located in the Veneto region of NE Italy. They interpret the fact that these cutmarks are almost exclusively found on wing bones of only a subset of the 22 species of birds found at Fumane as evidence that Neanderthals there specifically ...

Cell Phones Are Somehow Related To The Brain

by Neuroskeptic in Neuroskeptic

The BBC saysMobile phones 'affect the brain'The paper's from Nora Volkow and colleagues from NIDA in the USA. Volkow's best known for her work on addiction.47 people got 18FDG Positron Emission Tomography. This method measures brain glucose use as a proxy for how hard cells are working. They say that this makes it better than other kinds of PET which merely measure regional blood flow. I bet they really wanted to do this study with fMRI, because PET scans cost loads, but of course you can't take........ Read more »

The scientist-journalist divide: what can we learn from each other?

Psycasm - Feelin' Lucky? Is it more than just a feeling?

by Rift in Psycasm

Are you lucky? Perhaps you’re unlucky. What is luck, anyway?It’s tempting to consider it as some kind of magical force present in the ether, in which some individual seem more able to channel its influence than others.Alternatively, it may be a force unto itself, bestowing favour or ill-fortune upon those who cross its path.Both of those definitions, however, fail under scrutiny. This does not; (read more)

Cell Phones and Brain

by Arunn in nOnoScience (a.k.a. Unruled Notebook)

I was about to give this post a news-paper-like title Cell phone usage affects brain — then I figured I should be knowing that usage of anything by us, should affect our brain. So I have settled for this rather bland title. A research paper authored by nine (first author Nora D. Volkow, MD, National [...]... Read more »

The Effect of Pseudonymity on Blogger Credibility

by Colin Schultz in CMBR

In July, 2010, one corner of the blogosphere erupted with the seething, burning rage that online communities seem to have a unique ability to muster. The spark that lit bloggers’ fuse was a decision by SEED Media Group decision-makers to allow a team of writers from PepsiCo Inc. to operate a blog about nutrition and [...]... Read more »

A strange armored lobopodian from the Cambrian

by Chris Grinter in The Skeptical Moth

The early Cambrian seas (542-488 million years ago) had a plethora of strange and bizarre creatures almost unimaginable to even the best sci-fi dreamer.  As possibly one of the precursors to the Arthropoda (also Onychophora and Tardigrada), the lobopodian lineages represent a strange group of “worms with legs” that once roamed the ancient sea . . . → Read More: A strange armored lobopodian from the Cambrian...

The best offense is a good defensin

by Kevin Bonham in Food Matters

If you were going to design the perfect immune system, what would you do? This question is often posed to beginning immunology students, and the best answer may be so obvious that it doesn't occur to most. The best immune system is one that prevent pathogens from ever gaining access to your squishy bits in the first place.

And so we have barriers - lots of them. Unfortunately, the best barriers are not always practical. Plants have rigid cell walls that are almost impervious to pathogens, but p........ Read more »

Sweeping through a fly’s genome

by Razib Khan in Gene Expression

Credit: Karl Magnacca
A few days ago I titled a post “The evolution of man is no cartoon”. The reason I titled it such is that as the methods become more refined and our data sets more robust it seems that previously held models of how humans evolved, and evolution’s impact on our genomes, are being refined. Evolutionary genetics at its most elegantly spare can be reduced down to several general parameters. Drift, selection, migration, etc. Exogenous phenomena such as the flux........ Read more »

Clinical research and the popular press – the bottom batch of 2005

Brain Circuit Tied to Gambling Risk in Parkinson Disease Identified

by William Yates, M.D. in Brain Posts

Some of the drugs used to treat Parkinson disease (PD) increase the risk for pathological gambling.  This can have a significant economic adverse effect on some individuals.  I have previous posted on the use of amantadine in reducing pathological gambling in PD.  Although some medications may reduce the risk of pathological gambling, there is a need to further understand the mechanism of drug-related gambling behavior.Cilia and colleagues from the University of Toronto as well as........

Inherited Gifts May Not Include a Long Life

by Kari Kenefick in Promega Connections

Perhaps we are what we eat, but suddenly we can no longer rely on our parents, that is our genetic makeup, to determine how long we live. At least not according to Swedish researchers who published recently in the Journal of Internal Medicine. To be honest, “suddenly” is a bit of a misnomer; the study from which the [...]...
