Porn is good for you

by Bryan in Imaging Geek

Science has some good news for any pornhounds that may be out there. Porn may be good for you.Its long been though that porn is associated with a range of negative social attitudes; including promoting sexual violence and negative attitudes towards women. Turns out that, at least in the case of these two issues, this doesn't appear to be the case.In a finding sure to piss off some feminists:Now let’s look at attitudes towards women. Studies of men who had seen X-rated movies found that they ........ Read more »

The ability to recognize faces is inherited

by Mo in Neurophilosophy

THE perception and recognition of faces is crucial for the social situations we encounter every day. From the moment we are born, we prefer looking at faces than at inanimate objects, because the brain is geared to perceive them, and has specialized mechanisms for doing so. Such is the importance of the face to everyday life, that we see faces everywhere, even when they are not there.We know that the ability to recognize faces varies among individuals. Some people are born with prosopagnosia, th........ Read more »

“Bird” Wrists Evolved Among Dinosaurs

by Brian Switek in Dinosaur Tracking

If there is one persistent gripe that paleontologists have with dinosaurs on screen, it is that their hands are usually wrong. From Tyrannosaurus to Velociraptor, predatory dinosaurs are time and again shown with their hands in a palms-down position, something that would have been anatomically impossible (at least without moving the arms to which those [...]...

Tip of the Week: Caleydo for gene expression and pathway visualization

by Mary in OpenHelix

Recently while watching the #bioinformatics tag on Twitter I saw Khader Shameer mention Caleydo.  I was instantly hooked at the very clever visualization strategy that they are using to provide more surface area for examining the data you are interested in viewing.  Their specific topics are pathways and gene expression, but it got me thinking about various data types that I would like to see connected in this way.
To skip right over to Caleydo and start trying it out, go here: http://www.cale........ Read more »

New Study Confirms That "Ida" is Not Our Great-Great-Great-Great-Etc. Grandmother

by Laelaps in Laelaps



The exceptionally preserved skeleton of Darwinius, known popularly as "Ida." From PLoS One.




Almost ten months ago an international team of researchers introduced the world to an exquisitely-preserved primate from the 47 million year old oil shales of Messel, Germany. Dubbed Darwinius masillae, and nicknamed "Ida" and "The Link", the fossil was touted as one of our earliest primate ancestors in a massive media campaign worthy of a Hollywood blockbuster. Yet the trouble was that there was no........ Read more »

Geo-location services are very useful, helping you find a post office, ATM, decent restaurant, or hooking up with friends. They are commonly used in conjunction with smart phones and other mobile devices that ping your location (based on network coordinates or the global positioning system, GPS) back to the owner of a given system.

Tall Tales of Diabetic Amputations

by Shaheen Lakhan in Brain Blogger

Diabetes is the leading cause of nontraumatic amputation in developed nations. Lower-limb amputations are particularly common in type 2 diabetes and impose a substantial burden on the patient’s and caregiver’s quality of life, as well as profound economic and health care burdens for the individual and society. Many studies have attempted to outline the risk [...]... Read more »

Using GPS to remotely observe wildlife behavior

But sometimes wildlife biologists want to know more than just where an animal is located at any given time - sometimes they also want to know what an animal is actually doing...... Read more »

Hour-glass figure activates the neural reward centre of the male brain

by BPS Research Digest in BPS Research Digest

There's little doubt that many conceptions of attractiveness are faddish - the size zero female model being an obvious example. However, other notions of beauty are more hard-wired, perhaps reflecting an evolutionary adaptation. These aspects of appearance have come to be associated with fertility, signifying 'reproductive fitness' to potential mates. Male facial symmetry is one example. Another is the hour-glass female form. Men in cultures across world report a preference for women with a lowe........ Read more »

Unusual Headaches

by The Neurocritic in The Neurocritic

Headache, by Robert Magginetti (Tranquility Base)In the last post we learned about Alice in Wonderland syndrome, a rare phenomenon involving distortions of visual perception and body image, most often caused by migraines. Although a specialty practice in headache might seem dull [so to speak] at first glance to those interested in behavioral neurology, unusual and colorfully-named types of headaches can make things more interesting. In Case Studies of Uncommon Headaches (2006), Dr. Randolph Evan........ Read more »

Invasive species corrupt DNA, not just ecosystems (Fitzpatrick et al., PNAS 2010)

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


I rarely think about how invasive species affect genetics.  It’s always in terms of ecosystems or species: invasive brown tree snakes gobbling up birds and lizards in Guam, or zebra mussels overwhelming and altering the environment of the Great Lakes.  How one species outcompetes and replaces another, changing the natural system.  This is partly [...]...

Manipulating Fat in the Context of Slowing Aging

by Reason in Fight Aging!

Researchers have established to a more than reasonable degree that fat is important in longevity and aging. A compelling experiment in mice, for example, demonstrates that less visceral fat means a longer life. Then we have the link between fat and chronic inflammation, and the strong correlations between excess fat tissue and all of the common age-related conditions. Given all of this evidence, it shouldn't be surprising that at least some of those researchers interested in slowing down the agi........ Read more »

The inheritance of face recognition

by Grant Jacobs in Code for life

You’d think that recognising faces is one of those things that we all do well, or at least the vast majority of us do, yet in practice our ability to do this varies.
Recent twin studies present evidence that face recognition is heritable and is a distinct cognitive task in it’s own right.
At one end of [...]... Read more »

Land consumption and open space loss across U.S. cities

by Phil Camill in Global Change: Intersection of Nature and Culture


The issue of land use change is a complex, with many factors being important historically, such as

population growth (more land required for more people)
technology (e.g., automobiles made suburban expansion feasible)
economics (cheaper land and rents in suburbs compared to cities)
policy (things like 30-yr mortgages, mortgage insurance, and FHA loans had a large impact on urban sprawl [...]... Read more »
