Badass bacteria are thriving in your washing machine

by Piter Boll in Earthling Nature

by Piter Kehoma Boll You probably have heard of bacteria (and archaeans) that live in extreme environments on Earth, such as hot springs or lakes with high salinity, where most lifeforms would die horribly in a few seconds. We usually … Continue reading →... Read more »

MRI scanner sees emotions flickering across an idle mind

by Dr. Jekyll in Lunatic Laboratories

As you relax and let your mind drift aimlessly, you might remember a pleasant vacation, an angry confrontation in traffic or maybe the loss of a loved one. And now a team of researchers say they can see those various emotional states flickering across the human brain.

Paralympic athletes and the rise of the cyborgs

by gdw in FictionalFieldwork

Para and super? The Olympics are over. They’ve brought us some good stories, some nice records, and (self-citation alert!) a humble blog post about the ethics of doping. But the Paralympics, their less mediatized cousin, are in full swing. Paralympians from all over the world gather to wow us with their athletic prowess in the Paralympic […]... Read more »

How to Hold Scientific Journals Accountable?

by Neuroskeptic in Neuroskeptic_Discover

Writing in PLoS Biology, neurobiologist Thomas C. Südhof discusses Truth in Science Publishing: A Personal Perspective. Südhof is a Professor in the Department of Molecular and Cellular Physiology at Stanford. A veteran scientist, he's been publishing since 1982.

So what's the state of science publishing as Südhof sees it?

He first notes that "scientists, public servants, and patient advocates alike increasingly question the validity of published scientific results, endangering the publi... Read more »

ZIKV: antivirals and the cell cycle, TBK-1 relocalisation and immune signalling

by thelonevirologist in Virology Tidbits

Zika Virus (ZIKV) is an emerging flavivirus that was first isolated in 1947 from a sentinel monkey in Uganda as part of study that aimed to identify novel pathogens and despite sporadic local outbreaks in countries such as Gabon, Nigeria, Cambodia, Malaysia and Indonesia followed by the first major outbreak in Yap/Federal States of Micronesia 2007 only caused mild disease in humans with up to 80% of asymptomatic cases.

by Dr. Jekyll in Lunatic Laboratories

Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now researchers are advancing another potential approach using sugar alcohols—an abundant waste product of the food industry—mixed with carbon nanotubes.

Are rabbits lagging behind in basic pet care practices?

5-Formlycytosine (5fC): A new base?

by Eliza Bacon in EpiBeat

DNA methylation and hydroxymethylation are well-established key players in gene regulation. Although many would agree that 5hmC also plays a critical role, there is still some debate over whether it serves a functional role, or is merely an artifact of DNA de-methylation. Even still, other intermediates of de-methylation are actively being investigated. In a recent paper by Iuilaro et al. 2016, a group of scientists argue that 5-formlycytosine (5fC), an intermediate of DNA de-methylation, is a s........ Read more »

Unexpected improvement in core autism symptoms following a probiotic?

The paper by Enzo Grossi and colleagues [1] (open-access) is definitely worthy of a post today and the suggestion that the "appropriate use of probiotics" might be something to consider for at least some diagnosed as being on the autism spectrum.Accepting that I'm slightly curious as to what would be considered 'inappropriate use of probiotics', the Grossi paper describes the clinical journey of a boy aged 12 diagnosed with an autism spectrum disorder (ASD) accompanied by learning (intellectual)........

Entitlement -- a damning recipe for happiness

by Dr. Jekyll in Lunatic Laboratories

Entitlement--a personality trait driven by exaggerated feelings of deservingness and superiority--may lead to chronic disappointment, unmet expectations and a habitual, self-reinforcing cycle of behavior with dire psychological and social costs, according to new research. In a new theoretical model, researchers have mapped how entitled personality traits may lead to a perpetual loop of distress.

How Well Does Brain Structure Predict Behaviour?

by Neuroskeptic in Neuroskeptic_Discover

To what extent does brain structure correlate with different psychological traits? An interesting new paper from Massachusetts General Hospital researchers Mert R. Sabuncu and colleagues uses a new method to examine what the authors call the 'morphometricity' of various behaviours and mental disorders.

Sabuncu et al. define morphometricity as "the proportion of phenotypic variation that can be explained by macroscopic brain morphology" - in other words, the degree to which people with sim... Read more »

A 'characteristic chemical signature' to chronic fatigue syndrome?

Today I'm (belatedly) talking about the paper by Robert Naviaux and colleagues [1] (open-access) and some further peer-reviewed discussion concerning the metabolomics of chronic fatigue syndrome (CFS).

Learning to turn down your amygdala can modify your emotions

by Dr. Jekyll in Lunatic Laboratories

Training the brain to treat itself is a promising therapy for traumatic stress. The training uses an auditory or visual signal that corresponds to the activity of a particular brain region, called neurofeedback, which can guide people to regulate their own brain activity. However, treating stress-related disorders requires accessing the brain's emotional hub, the amygdala, which is located deep in the brain and difficult to reach with typical neurofeedback methods.
