Israel and Palestine are Both Fighting Back...?

by Neuroskeptic in Neuroskeptic

There are three basic schools of thought on the Israel / Palestine thing.Those evil Israelis are out to destroy Palestine, and the Palestinians are just fighting back.Those evil Palestinians are out to destroy Israel, and the Israelis are just fighting back.It's a cycle of violence, where both sides are fighting back against the other.Which one you subscribe to depends mostly on where you were born. I'm not aware of many people who've changed their minds on this issue, perhaps because doing so ........ Read more »

Better late than never: The Swedish mammography study and screening for women under 50

by Orac in Respectful Insolence

Last week blew by me in a blur. Because I was in full grant writing frenzy to get an R01 in the can by Friday, pretty much anything that wasn't totally urgent got shoved aside, at least after Wednesday. Of course, it was last Wednesday that yet another mammography study was being touted as a "landmark" study. I had just enough time to look it over briefly and decide that I really should blog about it, particularly given that it came hot on the heels of a Norwegian study less than a week before t........

The organic halo alters food and exercise choices

by Colby in

Nutrient-based claims on food labels are shown in some research to promote calorie underestimation.  This is often called the health halo effect; certain buzz words associated with what people consider healthy cause them to overgeneralize other attributes of a food, … Continue reading →...

Physical Strength Predicts Mortality

by Shaheen Lakhan in Brain Blogger

Aging gracefully is a challenge for all who are fortunate enough to be given the privilege of growing old.

MHC vs pathogens: Evolution showdown

by iayork in Mystery Rays from Outer Space

I’m not finding time to give these papers a full post each, so let me pool together several in the same theme: MHC alleles and protection against pathogens. It’s generally accepted that the reason there are so many MHC alleles is related to their ability to protect against pathogens.1 The version is probably the frequency-dependent [...]... Read more »

Finding platypus venom

by Grant Jacobs in Code for life

Platypuses*1 are one of Australia’s oddest creatures.
They’re furry, mainly nocturnal aquatic creatures that swim with their eyes shut paddling with their webbed front feet and steering (or braking) with their rear feet. Their homes are burrows in the river banks. While not endangered, water pollution is an issue for their survival.*2

Platypuses are monotremes, best known as [...]... Read more »

On Music and The Brain (3)

A study investigating the effect of musical training on memory, researchers used familiarity of a certain instrumental melody as a recollection measure to study the role of musical training on memory and recollection. By using fMRI and Voxel-based morphology assays, the differences in modes of recollection were studied among frequent listeners compared to musicians. The [...]... Read more »

Findings: The Causality Implicit in Language

by gameswithwords in Games with Words

Finding Causes

Consider the following:

(1) Sally hates Mary.
a. How likely is this because Sally is the kind of person who hates people?
b. How likely is this because Mary is the kind of person whom people hate?

Sally hates Mary doesn't obviously supply the relevant information, but starting with work by Roger Brown and Debora Fish in 1983, numerous studies have found that people nonetheless rate (a) as more likely than (b). In contrast, people find Sally frightens Mary more indicative of Sal........ Read more »

The Ig-Nobel Prize for Physiology and Medicine

by Brad Walters in Cortical Hemming and Hawing

While this is the time of year for the Nobel prizes (arguably the highest awards in science), it is also the time of year for the Ig-Nobel prizes which, according to the website "are intended to celebrate the unusual, honor the imaginative — and spur people's interest in science, medicine, and technology."  So, while the King of Sweden may be honoring Robert Edwards for his research leading to in vitro fertilization (IVF), the Ig-Nobels are honoring researchers in the Netherlands who disc........

Go with the blow: a non-invasive way to sample large whales…

A non-invasive strategy for ‘CETACEAN OBSERVATION’ (try to say that 5 times in a row):
Monitoring large populations of free-ranging whales for pathogens is extremely difficult because tissue samples are troublesome to obtain.  First, you’ve got to be close enough to physically remove a chunk of flesh, and second, you’re inflicting damage on the organism as [...]... Read more »

Runeson, the Ames Room and the Irrelevance of Equivalent Configurations

by Andrew Wilson in Notes from Two Scientific Psychologists

One of the most common objections to Gibson's ecological approach to perception is to point to illusions such as the Ames Room as evidence of how perception can be fooled, revealing the assumptions required. Gehringer & Engel (1986) put Gibson to the test against the Ames Room, but their final conclusion (that there was still a residual error, disproving Gibson) was based on a misreading of Gibson and numerous other key problems. Runeson's (1988) rebuttal stands as a model paper for an........ Read more »

Cognitive Stimulation Can Increase Creativity

Creativity plays a big part in most areas of everyday life. Sternberg and Lubart (1996) define creativity as the ability to produce work that is original, useful and, generative.

When errors detract from the message, who is to blame?

by Alistair Dove in Deep Type Flow

I am trying to read a paper right now but there are so many mistakes in it that I am really having trouble getting at the science because I am going mad over the errors.  Harikrishnan et al (2010) have written what is otherwise an important review piece about scuticociliatosis, which is a grab-bag name for the disease caused by several types of ciliated protists (single-celled organisms).  Two drugs are misspelled in the abstract (gentamycin as gentamycine and amoxicilin as amoxycilil........

Stamping out disease–from afar

by PalMD in White Coat Underground

In my opinion, people are often too embarrassed to see their doctor about sexually transmitted infections (STIs)—in my opinion. “In my opinion” is one of the most dangerous phrases in science.  But when in comes to attitudes toward STIs, the data are scarce. STI’s are very much a “behavior”-based disease, so knowing what attitudes prevail [...]... Read more »

Cross-cultural personality change throughout the lifespan: a result of brain development?

by William Lu in The Quantum Lobe Chronicles

It's not difficult to readily imagine the rebellious angst ridden teenager or the wise old man of very few words. McCrae, et al.’s 1999 research findings seem to have validated these prototypical depictions. They found that across various cultures (Germany, Italy, Portugal, Croatia, and South Korea) there were higher levels of neuroticism in young adults and decreases in extraversion and openness in older adults. Older adults also showed increase rates of agreeableness and conscientiousness. B........ Read more »
