Do Women Really Want Nice Guys?
by Annemarie van Oosten in United Academics
It’s a familiar story: women who say they are looking to date a kind, sensitive and emotionally expressive guy often end up dating a macho man or a jerk. This leaves many ‘nice guys’ feeling they always finish last. For many decades, researchers have tried to get a grip on this so called ‘nice guy paradox’.... Read more »

Hybrid Chimps in European Zoos
by Gunnar de Winter in United Academics
Our close evolutionary cousin, the common chimpanzee, comes in four subspecies, each one named after its location along an East-West band in Africa. Yet, there are chimps outside of Africa as well. Many European zoos possess a group of chimpanzees, which often plays a part in conservation plans. After all, the populations of our primate brothers are in steep decline. Habitat destruction, bushmeat hunting, pet trade and disease all take their to... Read more »

Mesenchymal stem cells against cancer
by beredim in Stem Cells Freak
Generally, the results from studies examining the effects of stem cells in treating cancer are mixed. Other studies indicate that stem cells promote tumour growth by forming new blood vessels while others suggest that stem cells halt tumour growth. Now, a new study on mice indicates that its all about "timing". The study was conducted by a collaborative team of researchers from the Université Joseph Fourier and the CHU de Grenoble hospital, both located in France.Read More... Read more »

School Choice Is Associated With More Student Engagement
by Eric Horowitz in peer-reviewed by my neurons
One thing I harp on a fair amount is that it’s a shame the concept of school choice has been bound to divisive rhetoric about competition and free markets. Every student is different, and therefore the presence of more choices always makes it more likely that a student will find a school that meshes with [...]... Read more »

Concussive Threshold: TBD?
by Jane McDevitt in Sports Medicine Research (SMR): In the Lab & In the Field
Take Home Message: Players sustained more head impacts and higher severity of impacts on days of diagnosed concussion compared to days with no diagnosed concussion. Also, peak linear acceleration was the best predictor of immediately diagnosed concussions.
Concussion prevention methods are difficult to develop because we lack an understanding of the relationship between head impact mechanics and subsequent concussions. We can improve our understanding by measuring impact forces during sportin........ Read more »

Factors Associated with Recovery from Anorexia Nervosa
by Tetyana Pekar in Science of Eating Disorders
Why do some people recover anorexia nervosa relatively quickly while others seem to struggle for years or decades? Does it depend on the person’s desire to get better? Their willpower? How much they are willing to fight? Is it just that some try harder than others? Some might say yes, but most will correctly realize that the picture is much, much more complex.
We can spend hours talking about barriers to treatment, but in this post I want to talk about something slightly different, somethi........ Read more »

House Sparrow communal courtship
by Africa Gomez in BugBlog
House Sparrows are quite vocal birds. In spring, a house sparrow colony is hard to miss, with males advertising their chosen nest sites to potential males by chirping and posturing, but mainly by their peculiar communal courtship. Communal courtships start when a fertile female not guarded by her mate flies by an unmated male, the male then will pursue her while chirping and displaying persistently soliciting copulation. More males usually join in the female chase and courtship in a cacoph........ Read more »

Science Sunday: Gut Reaction
by Mitchell Harden in Mitch's Blog
I recently read a 2006 paper titled "Visceral Influences on Risk-Taking Behavior." In spite of it's problems this paper uses some great language. Take for example this opening paragraph from the introduction:"People often do things that they almost immediately regret. Would-be dieters succumb to the lure of forsworn foods, only to curse their weak wills once their hunger (or the food) is gone. Unfaithful spouses live wracked with guilt after an impulsive sexual dalliance, only to repeat the cycl........ Read more »

A Massive Pulsar in a Compact Relativistic Binary
by Perikis Livas in Tracing Knowledge
Pulsar Tests Gravity
Because of their extremely high densities, massive neutron stars can be used to test gravity. Based on spectroscopy of its white dwarf companion, Antoniadis et al. (p. 448) identified a millisecond pulsar as a neutron star twice as heavy as the Sun. The observed binary’s orbital decay is consistent with that predicted by general relativity, ruling out previously untested strong-field phenomena predicted by alternative theories. The binary system has a peculiar combi........ Read more »

Blowing Bubbles from Our Galaxy
by Perikis Livas in Tracing Knowledge
In the center of our Galaxy lies a region called the Central Molecular Zone (CMZ). This region is filled with gas and is forming stars at a rate of about 0.1 M☉ yr-1 — enough to qualify it as a starburst region (a region with an abnormally high star formation rate), but relatively modest when compared to very active star-forming regions we observe in places such as M82, which clocks in at a rate 100 times higher. Thus the author suggests the CMZ might serve as somewhat of a prototype for........ Read more »

About Those Toltecs

With increasing evidence for Mesoamerican influence at Chaco in recent years, it’s worth taking a close look at what was going on in Mesoamerica itself during the Chacoan era. As I’ve mentioned before, there is some reason to believe that the most likely area to look to for direct influence in the Southwest is West Mexico, [...]... Read more »

Nectar feeding Blackcap
by Africa Gomez in BugBlog
Yesterday I heard a male Blackcap singing on my way to work. Although it was high on a tree, luckily, I had a small pair of binoculars with me and I found him on a Sycamore in bloom. While I watched it, the Blackcap alternated singing and clearly drinking from the Sycamore flowers, in one occasion clinging upside down from a branch like a tit to reach them. It is well documented that several European birds, especially warblers, regularly drink nectar (I have posted on Blue Tits feeding on Mahoni........ Read more »

Procrastination to find the most cited papers in Medical Imaging

Few day ago, I was wondering what were the most cited (important?) papers in Medical Imaging in the last ten/five/two years. The problem was that I didn't know exactly how to find this information. I googled a bit around and I found a way and tried it out. I found also some extra information about the subject:Published Papers in Radiology, Nuclear Science and Medical Imaging Field: Citations in Radiology, Nuclear Science and Medical Imaging Field:It is interesting to note that it is increasing s........
