Introducing Lassa-VSV, a hybrid virus that kills brain tumours

by Betty Zou in Eat, Read, Science

In a paper published this past week in the Journal of Virology, researchers at Yale University and Harvard University tried to overcome the neurotoxicity of VSV by engineering a hybrid virus. The researchers wanted to know if swapping out the G protein of VSV with the G protein from another virus would lessen the harmful effects of VSV on the brain while maintaining its tumour-killing abilities....

Kids with ADHD must squirm to learn

by Dr. Jekyll in Lunatic Laboratories

For decades, frustrated parents and teachers have barked at fidgety children with ADHD to “Sit still and concentrate!” But new research shows that if you want ADHD kids to learn, you have to let them squirm. The foot-tapping, leg-swinging and chair-scooting movements of children with attention-deficit/hyperactivity disorder are actually vital to how they remember information and work out complex cognitive tasks....

Is There Signal in the fMRI Noise?

by Neuroskeptic in Neuroskeptic_Discover

A new paper in Neuroimage suggests that methods for removing head motion and physiological noise from fMRI data might be inadvertently excluding real signal as well.

The authors, Molly G. Bright and Kevin Murphy of Cardiff, studied the technique called nuisance regression. It's a popular approach for removing fMRI noise. Noise reduction is important because factors such as head movement, the heart beat, and breathing, can contaminate the fMRI signal and lead to biased results. Nuisance regres... Read more »

Autistic traits in adult-onset psychiatric disorders?

by Paul Whiteley in Questioning Answers

"To conclude, the presentation of ALTs [autistic-like traits/symptoms] at the sub-threshold or threshold level may be closely associated with BPD [bipolar disorder] and SZ [schizophrenia]."That was the conclusion reached in the paper by Junko Matsuo and colleagues [1] (open-access here) based on their analysis of nearly 300 adults aged between 25-59 years including those diagnosed with "MDD [major depressive disorder], n=125; bipolar disorder, n=56; schizophrenia,&n........

Major Advance in Artificial Photosynthesis

by Perikis Livas in Chilon

A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels....

Study links brain anatomy, academic achievement, and family income

by Dr. Jekyll in Lunatic Laboratories

Many years of research have shown that for students from lower-income families, standardized test scores and other measures of academic success tend to lag behind those of wealthier students. Well now a new study offers another dimension to this so-called “achievement gap”After imaging the brains of high- and low-income students, they found that the higher-income students had thicker brain cortex in areas associated with visual perception and knowledge accumulation....

Artificial blood vessel lets researchers assess clot removal devices

by Dr. Jekyll in Lunatic Laboratories

For the first time, researchers have created an in vitro, live-cell artificial vessel that can be used to study both the application and effects of devices used to extract life-threatening blood clots in the brain. The artificial vessel could have significant implications for future development of endovascular technologies, including reducing the need for animal models to test new devices or approaches....

Peer review: bad with it, worse without it

by SciELO in SciELO in Perspective

Peer review is seen as one of the pillars - if not the most important - of scientific communication. Despite the difficulties in going through the review process, the authors believe that the process improves the quality of the manuscript, and they want to be published on refereed journals that have a sound evaluation mechanism. Recent cases of attempted manipulation of the peer review process by fake reviews concern the international scientific community, however, it does not undermine its cred........ Read more »

Sick Coyotes Are More Likely to Come into Cities

by Elizabeth Preston in Inkfish



Run-ins are on the rise between coyotes and city-dwelling humans, and scientists aren't sure why. Now researchers in Alberta think they've found a piece of the puzzle. Coyotes are more likely to creep into human spaces if they're unhealthy.

Conflict between humans and coyotes has increased during the last 20 years, write University of Alberta graduate student Maureen Murray and her coauthors. Yet coyotes were expanding their range for decades before that. They've spread to inhabit nearly ... Read more »

Mapping the language system: Part 2

by Dan Mirman in Minding the Brain

This is the second of a multi-part post about a pair of papers that just came out (Mirman et al., 2015, in press). Part 1 was about the behavioral data: we started with 17 behavioral measures from 99 participants with aphasia following left hemisphere stroke. Using factor analysis, we reduced those 17 measures to 4 underlying factors: Semantic Recognition, Speech Production, Speech Recognition, and Semantic Errors. For each of these factors, we then used voxel-based lesion-symptom mapping (........ Read more »

Marathon runners forget how painful it was

by BPS Research Digest in BPS Research Digest

Image: Flickr/GregThe sense of accomplishment from running a marathon is hugely uplifting. But let's not romanticise it, there's also a lot of pain involved. Despite this, many people pull on their running shoes time and again. A new study helps make sense of their behaviour – it turns out most marathon runners forget just how painful it was the last time. Przemyslaw Bąbel recruited 62 runners (39 men) who took part in the 11th Cracovia Marathon in Cracow, Poland in 2012. Moments after they c........ Read more »

Rhabdomyomas: an additional BHD hamartoma phenotype?

by Danielle Stevenson in BHD Research Blog

Hamartomas are benign, focal malformations formed by an excess of normal tissue growing in a disorganised fashion. Several hamartoma syndromes have been linked to aberrant mTOR signalling including BHD and Tuberous Sclerosis Complex (TSC). In addition to the predisposition of BHD patients to develop hair follicle hamartomas or fibrofolliculomas (Birt et al., 1977), Fuyura et al., (2012) propose that the pulmonary cysts in BHD patients are hamartoma-like cystic alveolar formations. The benign nat........ Read more »

Higher cancer mortality rates associated with mental illness

by Paul Whiteley in Questioning Answers

The findings reported by Steve Kisely and colleagues [1] were of some interest recently and their assertion that despite cancer incidence being "the same as the general population for most psychiatric disorders" or even slightly reduced when a diagnosis of schizophrenia was for example received, mortality due to cancer was "increased in psychiatric patients."Such findings were based on their examination of: "Mental health records [that] were linked with cancer registrations and death r........

Could maple syrup help cut use of antibiotics?

by Dr. Jekyll in Lunatic Laboratories

Another reason to have those waffles… well maybe. Researchers have found that a concentrated extract of maple syrup makes disease-causing bacteria more susceptible to antibiotics. In an ever increasing antibiotic resistant world, this news is almost as sweet as the syrup (okay no more bad puns). The findings suggest that combining maple syrup extract with common antibiotics could increase the microbes’ susceptibility, leading to lower antibiotic usage.... Read more »

What is Neurofeedback Training for ADHD?

by William Yates, M.D. in Brain Posts

There are a variety of behavioral strategies for treating the attention and activity components of attention deficit hyperactivity disorder (ADHD).One of these strategies is known as neurofeedback. A recent study in the journal Pediatrics found evidence for effectiveness of in-school neurofeedback for ADHD in a randomized controlled trial.In this trial, 104 children between the ages of 7 and 11 years of age were randomized to one of three research arms: in-school neurofeedback, cognitive th........

My colleagues and I have a pair of papers coming out in Nature Communications and Neuropsychologia that I'm particularly excited about. The data came from Myrna Schwartz's long-running anatomical case series project in which behavioral and structural neuroimaging data were collected from a large sample of individuals with aphasia following left hemisphere stroke. We pulled together data from 17 measures of language-related performance for 99 participants, each of those participants was also........
