It’s been a while since we’ve had a new cognitive bias to share with you. Previously we’ve blogged on many different biases and here are a handful of those posts. Today’s research paper combines three biases—two of which we’ve blogged about before: the better-than-average effect, confirmation bias and also, the endowment effect. The endowment effect […]...

Meet the Moroccan flic-flac spider (Cebrennus rechenbergi), a truly unique spider that when provoked or threatened escapes by doubling its normal walking speed using forward or backward flips similar to acrobatic flic-flac movements used by gymnasts.
C. rechenbergi is a species of huntsman spider indigenous to Morocco and can be found in the sand dunes of the Erg Chebbi desert . The spider ... Read more »

"While pregnant women should continue to avoid handling soiled cat litter, given possible T. gondii exposure, our study strongly indicates that cat ownership in pregnancy or early childhood does not confer an increased risk of later adolescent PEs [psychotic experiences]."So said the findings reported by Francesca Solmi and colleagues  (open-access) who brought a smile to any reader of the title of their paper: "Curiosity killed the cat: no evidence of an association between cat ownershi........

Can’t wait to break out of high school and dash off to college? College is a lot of fun. Late nights, parties, sporting events with thousands of people, on-campus concerts and thousands of potential new friends combine to make college some of the best years of a person’s life. Yet, in the midst of all […]

"In our cohort, high levels of antibodies to herpes simplex virus 2 at midpregnancy were associated with an elevated risk of autism spectrum disorder in male offspring. These findings provide support for the hypothesis that gestational infection may contribute to the pathogenesis of autism spectrum disorder and have the potential to drive new efforts to monitor women more closely for cryptic gestational infection and to implement suppressive therapy during pregnancy."That was the conclusion reac........

I just read a concerning paper about an experimental stem cell treatment for children with autism.
The authors are Himanshu Bansal and colleagues of India. The senior author, Prasad S Koka, is the Editor-in-Chief of the Journal of Stem Cells where the paper appeared, which raises questions about whether the manuscript received a thorough peer review. Koka is actually an author on all five of the research papers published in that issue of the journal. But that's a minor issue compared ... Read more »

OK I'm a little confused right now.Not so long ago I talked about the paper from Horvath and colleagues  (see here) concluding that "the limited data currently available suggest that ω-3 FA [omega-3 fatty acid] supplementation does not enhance the performance of children with ASD [autism spectrum disorder]."

Emotional intelligence (EI) is characterized by the ability to recognize emotional states in self and in others.This emotional recognition may be helpful in guiding behavior and in improving interpersonal relationships.It seems logical on a face validity level to assume that higher levels of EI would be good in the selection of students for medical school.However, there are few studies assessing EI in physicians. There are fewer studies that examine whether EI influences physician behavior, pati........ Read more »

How much damage can the brain take and still function normally? In a new paper, A Lesion-Proof Brain?, Argentinian researchers Adolfo M. García et al. describe the striking case of a woman who shows no apparent deficits despite widespread brain damage.

Breast cancer (BC) is the most common cancer among women and one of the leading causes of cancer-related deaths worldwide (1-3). It is a clinically heterogeneous disease, with at least 5 different subtypes (4) and quite variable prognosis, even within a subtype. In spite of early detection programmes, unfortunately 20-30% of early stage cases will eventually experience recurrence and develop distant metastasis. However, currently, there is no acceptable method for monitoring patients who are lik........ Read more »
