Feelin' Hot Hot Hot!

by Mark Lasbury in As Many Exceptions As Rules

Can you believe that having one disease will protect against another? Yes? Well, OK, but did you know that sometimes doctor’s give you one disease to help cure you of something worse? Like how people have been given malaria to kill off syphilis, or how the guy who invented the Heimlich maneuver wants to give people malaria to get rid of HIV. Weird.... Read more »

Autism prevalence in the Somali population in Minneapolis continued

by Paul Whiteley in Questioning Answers

A very quick post today to direct you to the paper by Amy Hewitt and colleagues [1] who seem to have finally published their findings on autism prevalence in the Somali population in Minneapolis in the peer-reviewed domain. I had previously covered their report on this blog (see here) and the suggestion that: "Somali (1 in 32) and White (1 in 36) children were about equally likely to be identified with ASD [autism spectrum disorder], but more likely to be identified with ASD than Black and ........

NAC for 'social impairment' in youth with autism... probably not

by Paul Whiteley in Questioning Answers

"The results of this trial indicate that NAC [N-acetylcysteine]  treatment was well tolerated, had the expected effect of boosting GSH [glutathione] production, but had no significant impact on social impairment in youth with ASD [autism spectrum disorder]."So said the results reported by Logan Wink and colleagues [1] (open-access) who, continuing an autism research theme, looked at whether this important L-cysteine prodrug might have more to give when it comes to a........

Zika Virus pathogenesis in adult mice: comparison to SINV ?

by thelonevirologist in Virology Tidbits

Until recently, clinical manifestations of ZIKV infection ranged from asymptomatic infections to mild dengue-like symptoms characterised by mild fever, rash, muscle/joint pain and headache. Following the 2007 epidemic however neurological complications following ZIKV infection including Guillan-Barre Syndrome (GBS) have been reported and during the current outbreak, ZIKV has been implicating to cause microcephaly and ocular malformations in foetuses born to ZIKV positive mothers. In the absence ........ Read more »

Where to Snuggle a Hedgehoglet

by Elizabeth Preston in Inkfish



Did you know this is Hedgehog Awareness Week? The British Hedgehog Preservation Society has dedicated May 1 through 7 to the spiny garden animal. The society won't go so far as to call it Hedgehog Appreciation Week—perhaps that would be too much of an imposition?—but it does want to highlight some of the problems faced by hedgehogs. For example, weed whackers, which apparently in the U.K. are called "strimmers."

The society suggests posting pro-hedgehog leaflets around your neighborho........ Read more »

Video Tip of the Week: expVIP, an Expression, Visualization, and Integration Platform

by Mary in OpenHelix

As I mentioned last week, I am watching a lot of farmers on twitter talk about this year’s North American growing season. To get a taste of that yourself, have a look at #Plant16 + wheat as a search. This is where the rubber of tractor tires and plant genomics hits the…well…rows. And just coincidentally […]... Read more »

The developmental correlates of asthma (again)

by Paul Whiteley in Questioning Answers

Can I just get it out of the way? May the 4th be with you.OK. The results from Mark Strom & Jonathan Silverberg [1] caught my eye recently and further evidence of a 'correlation' between asthma and developmental and/or behavioural outcomes. This time around it was "caregiver-reported speech disorders in US children" and how the appearance of asthma, hay fever and/or food allergy might show some important relationships with something like speech disorder. This follows other, similar work from........ Read more »

Flipping the Drake Equation for a deep time perspective on the Fermi Paradox

by gdw in FictionalFieldwork

Is anybody out there? Where are all the alien civilizations? Even if (intelligent) life is very unlikely, the sheer size and age of the universe means that even long odds might have produced space faring civilizations. Yet, so far, nada. When people are considering the (im)probability of non-human space travellers, one thing always comes up: […]... Read more »

Machine learning applied to autism screening going big time?

by Paul Whiteley in Questioning Answers

Machine learning, when machines, er.. learn, is of growing interest to the autism research field. The names Wall and Duda have filled quite a few posts on this blog (see here and see here for example) on this topic and their suggesting that applying machine learning algorithms to something like autism screening and detection could cut down on time taken and resources used.As per the publication of the paper by Daniel Bone and colleagues [1] it appears that others working in autism research are a........

Origin of synaptic pruning process linked to learning, autism and schizophrenia identified

by Dr. Jekyll in Lunatic Laboratories

Vaccines don't cause autism, but because the brain is so complex, we still don't know how much of it works so figuring out the real causes (as in more than one) of autism has been slow going. Well, researchers have identified a brain receptor that appears to initiate adolescent synaptic pruning, a process believed necessary for learning, but in this case it is one that appears to go awry in both autism and schizophrenia....

"Neuroscience-Based Nomenclature" for Mental Health?

by Neuroskeptic in Neuroskeptic_Discover

Psychiatric drugs come in many kinds: there are antidepressants, antipsychotics, anti-anxiety medications, and more. But what all of these categories have in common is that they're anti- something. This is how we classify these drugs - by what they treat.

Except there's a problem - very few psychiatric drugs are only used to treat one thing. Take "antipsychotics". They're used in psychosis, but they're also a key tool in the treatment of mania, a different disorder entirely. Many of these dru... Read more »

On defining chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME)

by Paul Whiteley in Questioning Answers

Most people who know a little bit about chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME) will probably understand the potential importance of the findings reported by Leonard Jason and colleagues [1] (open-access available here). Suggesting that there may be "four groupings of patients" when it comes to how we "name and define the illnesses", this research group who surveyed over 500 people "in the United States, Great Britain, and Norway" report on one of the biggest challenge........

Influence of religion and predestination on evolution and scientific thinking

by Dr. Jekyll in Lunatic Laboratories

Generally seen as antithetical to one another, evolution and religion can hardly fit in a scientific discourse simultaneously. However, in a new article, a biology researcher delves into observations on the influences a few major religions have had on evolutionists and their scientific thinking over the centuries.

Salts in the brain control our sleep-wake cycle

by Dr. Jekyll in Lunatic Laboratories

Insomnia, fun fact those of us who have served or are serving in the military have a much higher incidence of sleep problems. So if you are like me and have ever been prescribed something to help you sleep, you know that there are some unwanted side effects. For instance the time I lost memory of a whole day of interacting with people to the ambien I had taken the night before, not fun. Thankfully Danish researchers found that the level of salts in the brain plays a critical role in whether we a........ Read more »

Words On The Brain: A Semantic Map of the Cortex

by Neuroskeptic in Neuroskeptic_Discover

In a new Nature paper, Berkely neuroscientists Alexander G. Huth and colleagues present a 'semantic atlas' of the human brain. Huth et al. have mapped which brain areas respond to words, according to the semantics (meanings) of each word. It turns out that these maps are highly similar across individuals - which could have implications for 'mind reading' technology.



Huth et al. recorded brain activity with fMRI while seven volunteers listened to over two hours of audio narrative (taken fr... Read more »

The 'anti-neuroinflammatory activity' of oxytocin

by Paul Whiteley in Questioning Answers

Whilst the package inserts of the various drugs that modern medicine has at its disposal provides important information on potential mode of action, there is a growing realisation that drugs generally have quite a few more molecular targets than are perhaps listed. Take for example the quite commonly used (in some parts of the world anyway) compound called melatonin  that in some instances can provide almost miraculous relief when it comes to sleeping issues under certain circumstances. A d........ Read more »

Don’t retweet if you want to remember

by Dr. Jekyll in Lunatic Laboratories

The whole of human intelligence, right at your fingertips. Sure it might not make the layman an engineer or physicist, but if we want to learn about a particular topic the internet can give us that information. But you better hold on tight before you lose it. New research finds retweeting or otherwise sharing information creates a “cognitive overload” that interferes with learning and retaining what you’ve just seen.
