Continuing the theme of blogging outside of the core material typically included on this site, I couldn't resist a mention of the 'head-to-head' debate talked about in the article by Matthew Kurien and colleagues  published in the British Medical Journal (BMJ).As per the title of this post, the name of the game was gluten-free products being available on prescription here in Blighty, and in particular, the prescribing of gluten-free products to patients diagnosed with coeliac disease.

When we're feeling very tired, we sometimes remark that we're "half-asleep". But is this more than just a figure of speech? A new paper suggests that parts of our brain may actually 'fall asleep' even while we're still awake.
According to researchers Jeremy D. Slater and colleagues of the University of Texas, "local sleep" occurs throughout the human brain, with each brain region passing into and out of a sleep-like state over time. What's more, local sleep becomes more and more common in... Read more »

uring the current Zika Virus (ZIKV) outbreaks in the Americas, an increased number of cognitive malformations including but not limited to microcephaly in foetuses and neonates of mothers who had been infected with ZIKV during pregnancy, lead to the conclusion that ZIKV might be neuroteratogenic, a hypothesis that has been supported by findings that various ZIKV strains –including isolates from Asia such ZIKV SZ 01, ZIKV FSS13025 and H/PF/2013 as well as isolates from the Americas such as........

High fishing pressure tends to lead to proportionally fewer old and large individuals in fish stocks. It is feared that these demographic changes make the fish stocks more sensitive to climate variability and change. Statistical analysis of long-term survey data on cod eggs throws new light on the possible mechanisms.

Horse ‘licking and chewing’: is it a sign of learning, submission or stress?Guest post by Georgina (Gina) Bishopp (Hartpury College, UK). A little while ago I was having a lesson on my horse when my instructor beamed up at me and exclaimed, “There you go, she is licking and chewing – she’s really listening to you now, keep going!” and with excitement I continued on eagerly with the exercise we were practising. It wasn’t until the exhilaration of the moment had waned did I thin........ Read more »

I've talked about 'fecal microbial transplants' a.k.a the poo(p) transplant before on this blog (see here). That previous entry was about the more typical (and potentially life-saving) use of a poo transplant - where stool from one person is extracted, 'repackaged' and transferred to another person - albeit with caveats in terms of possible long-term side-effects. Now it appears that poo transplants are being investigated with something rather more central to the typical cont........ Read more »

Epigenetic regulation is thought to be one of the most important mechanisms contributing to the development and clinical course of chronic immunological diseases like allergies and asthma. DNA methylation has been extensively studied in this context, which has not been a case of histone modifications such as histone acetylation or methylation.
Early epigenetic studies from our lab conducted in mouse models demonstrated a role for histone acetylation in mediating bacteria-induced protection ag........ Read more »

Competition for government research grants to fund scientific research remains fierce in the United States. The budget of the National Institutes of Health (NIH), which constitute the major source of funding for US biological and medical research, has been increased only modestly during the past decade but it is not even keeping up with inflation. This problem is compounded by the fact that more scientists are applying for grants now than one or two decades ago, forcing the NIH to enforce strict........ Read more »
After a late dinner, a jungle-dwelling whip spider can't rely on an Uber driver to get her home. She has to find the way herself, in the pitch-black, picking her way over thick undergrowth to reach the tree she lives on. It's a trick she can even manage when plucked from her home tree and tossed into the forest at random, up to 10 meters away. Now scientists think whip spiders don't use her eyes for this homing feat—they use their feet.
