There may be a genetic connection between some mental health disorders and type 2 diabetes. In a new report, scientists show that a gene called “DISC1,” which is believed to play a role in mental health disorders, such as schizophrenia, bipolar disorder and some forms of depression, influences the function of pancreatic beta cells which produce insulin to maintain normal blood glucose levels.

Plasticity of the brain, what does that even mean? Well the good news is that it isn’t just a marketing ploy, the brain needs to be “plastic” because we need to be able to adapt. Frankly speaking, the brain still has a lot to learn about itself. Scientists at the Virginia Tech Carilion Research Institute have made a key finding of the striking differences in how the brain’s cells can change through experience.

As discussed before, Zika Virus (ZIKV) is an emerging arbovirus, spread by Aedes Agypti and Aedes albopictus, which was first isolated in 1947 in Uganda from a Macaca monkey with the first human case being detected in Nigeria (1954). In subsequent decades sporadic cases linked to ZIKV have been reported in Africa and Asia, with a first epidemic reported in 2008 (Yap/Federated States of Micronesia) and a larger one in French Polynesia and Oceania 2013-2014 with the first cases in the Americas were identified in Natal/Brazil in March 2015 in samples from patients displaying dengue-like symptoms. Here the connection of ZIKV infection with microcephaly is critically discussed.... Read more »

"The primary finding from the study was evidence of an improvement in several objective sleep parameters in participants in whom the increased colonization of lactic acid producing organisms was resolved after antibiotic treatment."Those were the words written by Melinda Jackson and colleagues  (open-access) who, during an open-label trial, looked at whether administration of an antibiotic (erythromycin 400 mg) over the course of 6 days might have some important effects on elements of sleep in a patient group diagnosed with chronic fatigue syndrome (CFS). Yes, sleep did seem to be [positively] affected was the finding. The suggested mode of action of antibiotic administration was linked to colonisation "with gram-positive faecal Streptococcus (determined by stool analysis and suggestive of abnormal gut functioning)" onwards to the idea that the those trillions of wee beasties that inhabit us all might show some specific connection to elements in cases of CFS.From an initial study population of 70 recruited for study, data for 22 participants (who completed the trial and met study inclusion criteria) were reported on. Those 22 all had "increased colonization of Streptococcus sp. (defined as >3×105 cfu/g of faecal sample)" as a pre-requisite to taking part in the trial based on the results of a "faecal microbiota analysis (FMA)." Actigraphy and sleep diaries were kept for a week before antibiotic use, during use and for 8 days after. Various facets of CFS symptoms were also examined during points of the study.Bearing in mind some 'malfunctions' affecting actigraphy results, the authors describe some interesting findings. First and foremost, is the idea that not everyone who took erythromycin showed the same profile (behavioural or biochemical). The authors talk about "responders" to the intervention (music to my ears) on the basis that: "Thirteen of the patients showed a reduction in Streptococcus counts after treatment, whereas four patients showed an increase level of Streptococcus and four patients had no change at the end of the trial." Outside of the idea that there may be some significant individual variation in the effects of antibiotics on gut flora (remembering the idea of 'swallowing a grenade'), questions abound as to why some people did not seem to be so affected by this strain of antibiotics whilst others did. Further: "While 13 participants showed a reduction in Streptococcus only 7 of these had a significant change as defined by a percentage distribution post-therapy of less than 6% of Streptococcus after antibiotic treatment." Mmm, indeed.Second, and linked back to the idea of 'responders' and 'non-responders' on the basis of microbiological results are the findings that there were: "more improvement in actigraphic sleep with treatment in responders compared to non-responders from baseline to post-treatment 2." Indeed, we are told that responders tended to increase their total sleep time by about 40 minutes between baseline and end of study, whereas: "non-responders slept an average of 15 min less from baseline to post-treatment 2."Finally, and quite importantly: "No significant change in any of the subjective measures was observed between baseline and the two follow-up points for responders versus non-responders." The subjective measures in question were linked to things like self-reported fatigue, mood and the such like. The authors have suggested that there may be some 'correlation' between a subscale on 'vigour' and "Streptococcus viable count" but when you're talking about 7 participants as your responder group, one has to be mighty careful of making too many sweeping generalisations.Although this is a preliminary study, I'd like to think that the Jackson findings might eventually be worked up into a larger, more methodologically sound research agenda encompassing a placebo arm and the like. We know for example, that sleep patterns can be affected by CFS and that at least subjective measures of sleep may affect the presentation of elements of CFS . That children and adolescents with CFS may be particularly vulnerable to sleep disturbances  is an area in specific need of further investigation. Moves therefore to improve sleep measures in CFS are perhaps to be welcomed mindful of the idea that persistent use of antibiotics is not exactly a great long-term strategy particularly in these days of growing antibiotic resistance. I could offer a possible alternative to antibiotic use that has been initially tried with CFS in mind (see here) but again, more research is indicated first and perhaps also some PR! Still, the focus on the gut microbiota and CFS/ME continues at a pace (er, maybe a should rephrase that) and with the promise of much, much more to come.I'll also be talking about the paper by Collin and colleagues in the not-too-distant future so watch this space...---------- Jackson ML. et al.

A lot of has been written about how focusing too much on materialistic ambitions, at the expense of relationships and experiences, can leave us miserable and unfulfilled. In a new paper published in Social Psychological and Personality Science, a team of psychologists at the University of British Columbia in Canada argue that there's another important distinction to be made – between how much we prioritise time versus money. Those who favour time tend to be happier, possibly because this frees them to enjoy pleasurable and meaningful activities, although this has yet to be established. The researchers led by Ashley Whillans first devised a quick and simple way to measure this difference in people. They asked just over 100 students to say whether they prioritised having more time or having more money, and to help them appreciate the distinction the researchers presented them with vignettes of two people – one who prioritises time:Tina (male names were used for male participants) values her time more than her money. She is willing to sacrifice her money to have more time. For example, Tina would rather work fewer hours and make less money, than work more hours and make more money. And one who prioritises money:Maggie values her money more than her time. She is willing to sacrifice her time to have more money. For example, Maggie would rather work more hours and make more money, than work fewer hours and have more time.The students answered this question twice, three months apart and their two choices were highly consistent, which supports the idea that people's prioritisation of time versus money is a stable trait.In several further studies involving thousands more students and adult members of the general public in Canada and the US, Whillans and her colleagues showed that people's answer to this one simple question correlated with their choices over various fictional scenarios, such as: whether they wanted to apply for a hypothetical higher salary/longer hours job or a lower salary/shorter hours alternative; whether they'd prefer a more expensive apartment with a shorter commute, or a cheaper alternative (to save money) and make a longer commute; and whether they actually chose a smaller cash reward for taking part in the study, versus a larger value reward token toward a time-saving service (such as a cleaner).What's more, across the studies, people who said they prioritised time tended to report being happier. This was true based on various ways of measuring happiness and wellbeing, and the association held even after holding constant many other factors, such as people's salary, education, hours of work and age and gender. The researchers also measured people's materialism and the association between happiness and favouring time over money remained after taking this into account.The researchers said that this relationship between prioritising time and being happier was "small but robust" – about half the size of the impact on happiness of things like being married and having more wealth. In an example of exemplary scholarship, the researchers make clear every factor they measured, every participant who was excluded and why, and the recruitment stopping rule for each study (i.e. how it was decided when to stop recruiting more participants). And perhaps most important, all their data is freely accessible via the Open Science initiative.As so often, it's worth remembering that this data was only recorded at a single point in the lives of the participants, so it's not yet been established that having more a time-centric orientation versus money-centric actually causes greater happiness – as the researchers acknowledge, it's possible that being happier allows people to see the value in saving time to do fun things. As well as longitudinal research (that follows people's priorities and happiness over time), future studies could also establish how people's time vs. money priorities change in response to important life events such as having children or retirement (the current data suggest that older people tend to favour time), and whether it's possible to deliberately change one's orientation."Although causality cannot be inferred," the researchers concluded, "these data point to the possibility that valuing time over money is a stable preference that may provide one path to greater happiness."_________________________________ Whillans, A., Weidman, A., & Dunn, E.

A recently paper published in
PNAS, members of the CEES Marine Group explores potential climate effects on
Calanus finmarchicus, a key zooplankton species in the North Atlantic. The paper shows how the combination of shallow mixed-layer-depth and increased wind apparently increases chlorophyll biomass in spring, and in turn
C. finmarchicus biomass in summer. These findings strongly suggest bottom-up effects of food availability on zooplankton, and highlight the need to consider climate effects “beyond temperature” when projecting zooplankton dynamics under climate change.

"Vitamin D deficiency might contribute to the aetiology of ASD [autism spectrum disorder]. Supplementation of vitamin D3, which is a safe and cost-effective form of treatment, may significantly improve the outcome of some children with ASD, especially younger children."More big words have appeared from a research group who seem to be particularly interested in how vitamin D (the sunshine vitamin/hormone) might have some important links to at least some cases of autism. The findings this time around come in the form of the paper by Feng and colleagues  who following on from their case-report  on what happened when a 2 (nearly 3) year old boy diagnosed with an ASD was given a supplement to correct an underlying vitamin D deficiency, now report on a larger participant cohort.In line with their clinical trial registration (see here) "last refreshed on 2015-05-02" a selection of 37 children from a bank of 215 diagnosed with an ASD "received vitamin D3 treatment" for 3 months alongside various measures of autistic behaviours (CARS and ABC) being delivered. Compared with a control group of 285 'do-not-have-autism' children, serum levels of 25(OH) vitamin D were lower in the children with autism as a group (n=215). Given what has been discussed before in the peer-reviewed literature, and from more than one independent source, these findings are not a great surprise. Further, we are told that: "After vitamin D3 supplementation, symptom scores were significantly reduced on the CARS and ABC. In addition, the data also suggest that treatment effects were more pronounced in younger children with ASD."Whilst potentially important findings, I do think we have to be slightly careful before singing the [universal] praises of what vitamin D might do for all autism at the current time. As far as I can make out, this was not a clinical trial insofar as pitting vitamin D supplementation against a placebo, nor was it the case that comparisons on behavioural or biological measures were made between supplementing children with autism and supplementing controls. This was, in effect, a study of 37 autistic children receiving a vitamin D supplement and the reporting on scores 'of autism' before and after such supplementation, all the while knowing that children were taking a vitamin D supplement.That's not however to say that my cautious view on this might not change in future as more controlled research is on-going in this area (see here and see here) and indeed, even talking about the possibility that vitamin D might affect the recurrence of autism in families where a child has already been diagnosed with autism (see here). We await the results of these various investigations in the peer-reviewed journal press to further inform clinical practice and perhaps also determine who might be the 'best' and non-responders to such intervention.The final question concerns what the possible mechanism(s) could be such that vitamin D supplementation, more traditionally indicated to treat skeletal issues, could potentially impact on the presentation of behaviours pertinent to autism. I don't have any substantial ideas about possible ways of working at the present time, outside of highlighting the various extra-skeletal effects that have been talked about outside of the primary autism research literature (see here and see here). I just might be tempted to suggest that any biological effect is likely to be complicated and not necessarily just related to how much vitamin D a person gets or doesn't (see here and see here). I'm also minded to bring in the idea that vitamin D might show some 'connection' to autoimmune diseases (see here) and where that could potential lead with at least some autism in mind (see here and see here). And then there is the possibility that supplementing with vitamin D might not be the only option to be explored  potentially also tied to other autism findings (see here).Speculation abounds and science has a lot more to do to catch up.Music: The Carpenters - Top Of The World.---------- Feng J. et al.

Genes could help in determining whether a person likes to rise early in the morning or not.
Researchers, in affiliation with 23andMe, Inc. recently worked on the DNA of 89,283 individuals, and found that genes could show some specific variations more frequently in the people, who self-identify themselves as early risers or morning people. They found 15 different spots in the genetic makeup that can vary between morning people and self-reported evening people. Seven of those variations were found near genes that are involved in controlling a person’s daily cycle, known as circadian rhythm.
Study also showed that many people, i.e. more than 50% consider themselves as night people. Adults and females represent more numbers as morning people, i.e. in the study 39.7% morning people were males and 48.4% were females. If a father is a morning person, his son has 1.9 times higher chances of becoming a morning person and his daughter has 2.4 times higher chances of becoming a morning person. Moreover, morning people suffer less from sleep apnea or insomnia as compared to night people; though, genes or genetic variations may not have any role in this aspect. On a further note, night people have more chances of getting depression as well as other health issues such as obesity.
“With the information we have, we can uncover the genetics behind a variety of conditions and diseases, and hopefully reach a better understanding of how we differ from one another,” noted 23andme senior researcher David Hinds in a press statement.
