History of neuroscience: John Hughlings Jackson

by neurosci in Neuroscientifically Challenged















In 1860, when John Hughlings Jackson was just beginning his career as a physician, neurology did not yet exist as a medical specialty. In fact, at that time there had been little attention paid to developing a standard approach to treating patients with neurological disease. Such an approach was one of Jackson's greatest contributions to neuroscience. He advocated for examining each patient individually in an attempt to iden........ Read more »

Parental exposures and risk of offspring autism: some curious details

by Paul Whiteley in Questioning Answers

"Overall, our results were consistent with no positive association between parental asthmagen exposure and ASD [autism spectrum disorder] in the children."So said the findings reported by Alison Singer and colleagues [1] (open-access) continuing a research theme from this group [2] looking at whether "parental workplace exposures to risk factors for asthma (“asthmagens”)" might have relevance to offspring risk for autism.Based on data derived from some of those oh-so-important Scan........

DHM attenuates obesity-induced slow-twitch-fiber decrease via FLCN/FNIP1/AMPK pathway

by Joana Guedes in BHD Research Blog

Obesity is often associated with decreases in the proportion of skeletal muscle slow-twitch fibers and insulin sensitivity. Slow-twitch fibers are rich in mitochondria and utilize fatty acid oxidative phosphorylation for energy production. In their new study, Zhou et al. (2017) explore the role of the FLCN/FNIP1/AMPK signalling pathway in obesity-induced reductions in slow-twitch fibers and insulin sensitivity in skeletal muscle using high-fat-diet-induced (HFD) obese mice, ob/ob mutant mice, an........

"a gradual decline in recorded diagnoses of CFS/ME since 2001"?

by Paul Whiteley in Questioning Answers

The quote forming the title of today's post comes from the paper by Simon Collin and colleagues [1] (open-access available here) who, based on analysis of the UK "Clinical Practice Research Datalink (CPRD), formerly known as the General Practice Research Database (GPRD)" set out to look at the "Incidence of CFS/ME [chronic fatigue syndrome/ myalgic encephalomyelitis], FM [fibromyalgia], post-viral fatigue syndrome (PVFS), and asthenia/debility." I say incidence but that last sentence s........ Read more »

Bright highlands in equatorial Venus likely ferro-electric. What's up with the high-latitude highlands?

by Paul Wren in Venus Dispatches

OverviewA lot of papers have been written about the highly reflective highlands (in radar) on Venus, with several different hypotheses (e.g. high porosity, metal frost).  Allan Treiman, Elise Harrington, and Virgil Sharpton look specifically at high-latitude highlands in comparison to highlands in the equatorial regions.  Both areas feature high reflectivity, but the reflectance patterns are distinct, as they describe in Venus' radar-bright highlands: Different signatures and mate........

"Asthma was associated with increased risk for schizophrenia"

by Paul Whiteley in Questioning Answers

'Big data' Taiwan is once again the topic of a post on this blog as the results published by Wei-Chen Wang and colleagues [1] (open-access available here) receive an airing, specifically that: "Asthma was associated with increased risk for schizophrenia."There are some common themes attached to these findings. Taiwan is already a research-favourite place on this blog as a result of their use of the National Health Insurance Research Database (NHIRD) for various research purposes. I can't na........

The continuing trials and tribulations of PACE

I honestly hadn't intended talking about the PACE trial - "pacing, graded activity, and cognitive behaviour therapy: a randomised evaluation" in relation to chronic fatigue syndrome (CFS) - quite so much on this blog. Others have done it so much better than I ever could.My interest however keeps being piqued in relation to the results originally produced suggesting that: "CBT [cognitive behaviour therapy] and GET [graded exercise therapy] can safely be added to SMC to mo........

The growing use of social networks for various purposes, including the dissemination of scientific communication, has required the creation of a new method of measuring and analyzing the flow of information in these environments. Altmetria emerged as a subarea of Metrics Information Studies to meet this need, and can complement traditional methods of evaluation, thus making it more fair and egalitarian. … Read More →...

Discovery of a 150 day period in the Venus condensational clouds

by Paul Wren in Venus Dispatches

OverviewUsing near infrared (NIR) data from the VIRTIS instrument that once traveled aboard the Venus Express spacecraft, Kevin McGouldrick and Constantine C. C. Tsang found a periodic variation in radiance, most intense at the mid-latitudes.  The paper is here.What Did They Find?They identified A 150-day periodic variation in radiance within the 1.74 µm and 2.30 µm windows, which is most pronounced between 30° and 60° latitude.  They also found that in these mid-latitudes, ra........

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 »

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 »

Risking Limb for Life? (A Guest Post)

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........
