Cephalopod Consciousness Part 2: The Case for Animal Consciousness

by Mike Mike in Cephalove

In this second post of the series “Cephalopod Consciousness”, I’ll talk about the methods that scientists have used to attempt to study consciousness in animals. For perhaps the first time in the history of this blog, I’ll write about science without making any specific reference to cephalopods – I’m saving that for part 3. Here [...]... Read more »

Drawing pain

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

The pain drawing has to be one of the more ubiquitous assessment tools around. There are many versions of outlines of naked bodies on which a person can scribble, colour, and write to indicate to treatment providers exactly where they feel their pain, and to a certain extent, some of the sensory features of that … Read more...

Plumes, Microbes, and Hypoxia…Did, Do, or Will They Exist in the Gulf

by Dr. M in Deep Sea News

The internets are a buzz with a new paper published in Science. You may recall I covered the new paper by Camilli et al. in Science demonstrating that a deep-water oil plume did exist, conclusively, in Gulf of Mexico at the time the researchers sampled, approximately May-June.  One of the interesting findings was that at the . . . → Read More: Plumes, Microbes, and Hypoxia…Did, Do, or Will They Exist in the Gulf...

No good deed goes unpunished

by Kris-Stella in Coffee Shop Philosophy

In Estonia, there is an old saying: "No good deed goes unpunished." Yes, you read that right: folk wisdom warns Estonians about being too unselfish because good deeds do not get rewarded. Instead, the performer of good deeds depletes their own resources but receives, if anything, bad things in return. Does that sound too cynical for you? Well, now this old proverb has a piece of social psychology research to fall back on. A recent article by Parks and Stone in The Journal of Personality and Soci........ Read more »

Big ideas in sleep: Borbély's Two Process Model

by 神経オタク in Cognitive Convolutions

I think I'm sticking with sleep for now. I enjoy it, and I'm familiar with the literature a little better than other sub-fields. I may even try to volunteer in a sleep/circ lab the following semesters(!). In any case, I won't pretend to be an expert either... Definitely not, and I really don't want to step on anyone's toes. But sleep is FUN for me, so that's what I'm doing. For now. Unless I find... Read more »

What would a Zostera blog be without a Zostera entry?

by John Carroll in Chronicles of Zostera

In the most recent issue of Marine Biology, there is a manuscript addressing the issue of 2 introduced species and their interactions with one another. Its an interesting read - one of the species is a commercially important bivalve, the Manila clam, which was introduced in the early 20th century and is now one of the most commercially harvested clams on the west coast of the US. The second is Zostera japonica, dwarf eelgrass, an introduced seagrass species which can establish itself on tidal ........ Read more »

Ep 135: Why do I sneeze at the Sun?

by westius in Mr Science Show

Do you sneeze at the Sun?

I do. My brother does. Both my parents do. In fact, we are a family of Photic Sneeze sufferers.

The Photic Sneeze Reflex (PSR), also known rather ridiculously as Autosomal Dominant Compelling Helioophthalmic Outburst (ACHOO) Syndrome (how long do you think it took researchers to figure out that acronym....) is a dominant genetic condition affecting around 10% of the population. When a sufferer moves from a region of darkness to a region of bright light - for instance,........ Read more »

Library love

by Emma in we are all in the gutter

I love libraries. I’m a member of four, not including University ones. Without libraries and the ability to borrow whatever I fancy, I think I’d be broke and living in a book-cave! So, I was sad this morning to hear that the number of adults visiting libraries in the UK has been decreasing steadily over [...]... Read more »

Neuroimaging of language: Why hasn't a clearer picture emerged?

by Greg Hickok in Talking Brains

This is the question raised in a paper by Evelina Fedorenko and Nancy Kanwisher published last year in Language and Linguistics Compass. The main point that they want to make is that language neuroimagers need to stop doing group studies and start doing functional localization in individual subjects, like the vision folks do. I don't disagree at all; e.g., see this post. In fact, we have used individual subject analyses in several of our papers (e.g., Okada & Hickok, 2006; Okada et al., in pr........ Read more »

Neuroscience of Murder and Aggression: Epidemiology

by William Yates, M.D. in Brain Posts

This is the second in a five part series on the neuroscience of murder and aggression.  This post will address some key issues in the epidemiology of murder and antisocial personality disorder.  The number of murders in the U.S. has been stable at between 16,000 and 17,000 per year over the 2000 to 2008 time period..  The number peaked at around 24,700 in 1991.  The number has decreased since the early 1990s despite a steadily increasing total U.S. population.The reason for t........

Bunches and Antibunches of Atoms: Hanbury Brown and Twiss Effects in Ultracold Atoms

by Chad Orzel in Uncertain Principles

Two papers in one post this time out. One of these was brought to my attention by Joerg Heber, the other I was reminded of when checking some information for last week's mathematical post on photons. They fit extremely well together though, and both relate to the photon correlation stuff I was talking about last week.

OK, what's the deal with these? These are two papers, one recent Optics Express paper from a week or so ago, the other a Nature article from a few years back. The Nature paper inc........ Read more »
