Perspectives…

by Sergio Graziosi in Writing my own user manual - Sergio Graziosi's Blog

In the past few months I’ve spent some time looking for trouble on Twitter. I’ve found some (mild and polite), which translated into plenty food for thought, and eventually allowed me to put some order in my thoughts. The matter…Read more ›... Read more »

Well below 1%

by Marco Frasca in The Gauge Connection

When a theory is too hard to solve people try to consider lower dimensional cases. This also happened for Yang-Mills theory. The four dimensional case is notoriously difficult to manage due to the large coupling and the three dimensional case has been treated both theoretically and by lattice computations. In this latter case, the ground […]... Read more »

Video Interaction for Promoting Positive Parenting in autism: yes but not quite...

"Video feedback may help babies ‘at risk of autism’" went one write-up of the study results published by Jonathan Green and colleagues [1] (open-access available here). Continuing a theme of kids at risk of autism potentially 'avoiding' an autism diagnosis (see here) following the use of "a 12-session parent-mediated social communication intervention delivered between 9 and 14 months of age (Intervention in the British Autism Study of Infant Siblings-Video Interaction for Promoting Positive ........

Flyfocals: Vision and Vectors Help Hunting Robber Flies

by Melissa Chernick in Science Storiented

Image credit: Thomas ShahanRobber flies (Asilidae family) are not your typical house flies. They are small, predatory insects that feed on a vast array of other arthropods. While they are small in size (10 times smaller than a dragonfly), these guys are serious hunters. For example, Mallophora omboides is known as the “Florida bee killer” for its taste for honey bees. Other robber flies hunt down wasps, dragonflies, spiders, or grasshoppers, just to name a few. Perhaps almost as impressive a........ Read more »

On a 'bidirectional relationship' between depression and autoimmune disorders

by Paul Whiteley in Questioning Answers

"We replicated the finding that autoimmune disorders are frequently comorbid with depression, using a longitudinal national birth cohort and self-report data, which is increasingly used in the study of depression."So said the findings reported by Jack Euesden and colleagues [1] (open-access) adding further to a growing peer-reviewed literature base [2] citing a 'connection' between immune function/dysfunction and the presentation of psychiatric/behavioural features (see here). And yes,........ Read more »

Risking Limb for Life? (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

By Matthew Whitley Imagine you are walking alone in parking lot, when suddenly somebody grabs you by the arm and flashes a knife, demanding your money. Do you A) scream for help, B) try to wrestle the knife away, or C) remove your arm from your shoulder and make a break for it? Disarming your assailant may seem preferable to dis-arming yourself, but for a lizard option C is a likely response. A lizard tail left behind.

Looking for clues for past life on Mars

by EE Giorgi in CHIMERAS

NASA's Curiosity Mars. Credits: NASA/JPL-Caltech/MSSSOn August 6, 2012, the NASA Curiosity rover landed on Mars at the base of Mount Sharp, a mountain the size of Kilimanjaro (~19,000 feet) in the middle of Gale Crater. Nina Lanza, space scientist at the Los Alamos National Laboratory, remembers the day well. As part of the team that built ChemCam, one of the ten instruments on the rover, she spent three months at the Jet Propulsion Laboratory in California, living on “Mars time” to fol........

How Electron Beams Produce Continuous Coherent Plasma Emission by H. Che, M. Goldstein, P. Diamond, and R. Sagdeev

by CESRA in Solar Radio Science

It is commonly accepted that energetic electron beams can produce drift frequency radio emission or Type III bursts since Ginzburg and Zhelezniakov first proposed the idea in 1958. However, the electron two-stream instability time (see reference 2) in the corona is fraction of a second, while the duration of coronal Type III bursts lasts several orders of magnitude longer. This problem is called the “Sturrock Dilemma” and remains a subject [...]... Read more »

Risk of death by injury and autism

by Paul Whiteley in Questioning Answers

"Individuals with autism appear to be at substantially heightened risk for death from injury."That was the research bottom line published by Joseph Guan & Guohua Li [1] from Columbia University Medical Center, who trawled the accumulated data included in the US National Vital Statistics System screening death certificates issued between 1999 and 2014. Of the approximate 32 million death certificates issued, researchers found that some 1300 people diagnosed as on the autis........ Read more »

"Predisposition" to autoimmunity and inflammatory activation linked to autistic regression?

by Paul Whiteley in Questioning Answers

The paper by Ori Scott and colleagues [1] provides some very welcome interest in the concept of regression in relation to autism. As I've indicated quite a few times on this blog, regression accompanying cases of autism has [finally] been accepted by the research community at large (see here for example) but there is still some way to go with regards to the hows-and-whys of regression. There are some clues (see here) but more data is required. What the evidence available so far suggests is ........ Read more »

One more time folks... pregnancy folate and autism risk

Sorry but that's just how the peer-reviewed papers have fallen..."Maternal folate supplementation during pregnancy may reduce the risk of ASD [autism spectrum disorder] in the offspring, especially in the Western population."So said the meta-analysis by Yu and colleagues [1] reporting on a topic that has seen quite a lot of research interest down the years (see here).

Are we in the GSM Radar?

by SciELO in SciELO in Perspective

Google Scholar Metrics (GSM) offers alternative metrics to the JCR Impact Factor and the SJR, namely the h-5 index. To enter this world ranking that covers more than 40,000 journals it is only necessary to publish an average of 20 articles per year and be cited. However, there are hundreds of journals (our journals) that are not being indexed in GSM. They're off Radar. … Read More →... Read more »

Novel FLCN mutations in Chinese patients

by Joana Guedes in BHD Research Blog

The gene FLCN is inactivated in individuals with BHD syndrome. The FLCN gene encodes the protein Folliculin, which is a putative tumour suppressor. Over 150 different FLCN mutations have been identified, most of which are likely to be pathogenic (LOVD-hosted FLCN mutation database). The majority of these mutations are frameshift, nonsense, insertion/deletion, or splice site mutations, resulting in truncation and inactivation of the encoded protein folliculin. FLCN consists of 14 exons spanning a........ Read more »

Folate-dependent one carbon metabolism and transsulfuration pathways: biomarkers for autism?

I found it a little unusual that the findings reported by Daniel Howsmon and colleagues [1] (open-access) talking about "multivariate statistical analysis presented herein [provided] unprecedented quantitative classification results for separating participants into ASD [autism spectrum disorder] and NEU [neurotypical] cohorts based solely on biochemical data" merited a rapid reply in a prominent science magazine pouring cold water on the results (see here).

"a single intravenous infusion of autologous umbilical cord blood" and autism

'Could stem cells offer hope for autism?' went one media headline referencing the very preliminary "phase I, open-label trial" published by Geraldine Dawson and colleagues [1] (open-access) detailing the experiences of a single intravenous infusion of autologous umbilical cord blood in 25 children with "a confirmed diagnosis of ASD [autism spectrum disorder]."Well, the results were promising in respect of important issues such as safety in light of the tenet 'first do no harm': "Assess........

Paediatric congenital heart disease and autism risk (again)
