The mysterious fart

by Dr. Jekyll in Lunatic Laboratories

Everyone does it ...no, not poop, but fart. Passing gas, fuming, crop dusting, cracking a rat -- no matter what you call it -- everyone fart, but why? Researchers have published an article devoted to the review of gaseous neurotransmitters of microbial origin and their role in the human body.

Fungi found flourishing following fire

by Rosin Cerate in Rosin Cerate

Morels and several other fungi (all members of the order Pezizales) are known to produce their mushrooms in recently burned soil, whether it's the result of a nice little campfire or an entire forest going up in smoke. The fire creates the right conditions for the fungus, which lies beneath the ground and so protected from flames and heat, to send up mushrooms. These mushrooms release spores into the environment, and the circle of life continues ever onward.In the case of morels, it's thought a ........ Read more »

Probiotics degrading gluten peptides - part 2

by Paul Whiteley in Questioning Answers

I going to assume that readers have some background knowledge about probiotics, gut bacteria, bacterial dysbiosis and coeliac disease before reading this post. I'd love to be able to give detailed descriptions of each here but fear that this would turn a short post into a much longer one...So... in a previous post titled: 'Probiotics degrading gluten peptides?' I covered the potentially important suggestion that certain types of bacteria might have the ability to breakdown (degrade) immunog........ Read more »

Wave that claw: how male crabs attract mates

Male Ilyoplax pusilla crabs wave their claws in the air to attract females, but why do different-sized males spend different amounts of time waving? The answer lies in research published this year. ... Read more »

Embryonic gene Nanog reverses aging in adult stem cells

by Dr. Jekyll in Lunatic Laboratories

The fountain of youth may reside in an embryonic stem cell gene named Nanog. In a series of experiments, the gene kicked into action dormant cellular processes that are key to preventing weak bones, clogged arteries and other telltale signs of growing old. The findings also show promise in counteracting premature aging disorders such as Hutchinson-Gilford progeria syndrome.

Risk of cancer in mums of children with autism

by Paul Whiteley in Questioning Answers

I very carefully approach the findings reported by Jennifer Fairthorne and colleagues [1] today detailing "the occurrence of hospital admissions and treatment/services for cancer in mothers of children with ASD [autism spectrum disorder] with or without ID [intellectual disability] compared with other mothers." Appreciating that families touched by autism probably have enough on their plate without additional talk about the 'big C', I do however think that this kind of r........ Read more »

Researchers temporarily turn off brain area to better understand function

by Dr. Jekyll in Lunatic Laboratories

Capitalizing on experimental genetic techniques, researchers have demonstrated that temporarily turning off an area of the brain changes patterns of activity across much of the remaining brain. The research suggests that alterations in the functional connectivity of the brain in humans may be used to determine the sites of pathology in complex disorders such as schizophrenia and autism.

Brain activity and response to food cues differ in severely obese women

by Dr. Jekyll in Lunatic Laboratories

The brain's reward centers in severely obese women continue to respond to food cues even after they've eaten and are no longer hungry, in contrast to their lean counterparts. The study compared attitudes and the brain activity of 15 severely obese women (those with a body mass index greater than 35) and 15 lean women (those with a BMI under 25).

A New Map of the Brain: What Does It Mean?

by Neuroskeptic in Neuroskeptic_Discover

A new Nature paper has earned a lot of media attention, unusually given that it's a fairly technical and 'basic' piece of neuroscience. In the paper, researchers Matthew F. Glasser and colleagues present a new parcellation (or map) of the human cerebral cortex, breaking the cortex down into 180 areas per hemisphere - many more than conventional maps.



But is this, as Nature dubbed it, "the ultimate brain map"?

To generate their map, Glasser et al. first downloaded 210 people's data from... Read more »

On probiotics and irritable bowel syndrome (IBS)

by Paul Whiteley in Questioning Answers

Granted, I am taking a slight departure from the material typically discussed on this blog by introducing the paper by Yan Zhang and colleagues [1] who reported the findings of a meta-analysis examining "the efficacy of different probiotic types, doses and treatment durations in IBS [irritable bowel syndrome] patients diagnosed by Rome III criteria via a meta-analysis of randomized controlled trials (RCTs)." The results however - "Probiotics are an effective pharmacological t........ Read more »

When it comes to empathy, don't always trust your gut

by Dr. Jekyll in Lunatic Laboratories

Ever feel like someone is hiding something? Or maybe you suddenly feel like you can't trust a co-worker. The feeling may seem logical, but is empathy the result of gut intuition or careful reasoning? Research suggests that, contrary to popular belief, the latter may be more the case.

Video of Evaporating Booze Droplet Looks Like a Tiny Planet

by Elizabeth Preston in Inkfish



Most of us don't give much thought to drops of liquid that end up outside our drinking glasses. But physicists care a lot about liquid droplets, and study their whole lifespans—from the first splash or drip to the moment a drop disappears.

Liquids that contain three different substances, though, haven't been studied as much. Detlef Lohse, a physicist at the University of Twente in the Netherlands, and his colleagues took a deep dive into one such liquid: ouzo.

Ouzo is a mixture of wate... Read more »

Altruistic people have more sex

by BPS Research Digest in BPS Research Digest

People who perform regular altruistic acts like giving blood also tend to have more sex.Viewed through the lens of evolutionary psychology, altruism takes some explaining. In a dog eat dog world, it seems like a risky, indulgent habit. Yet we are only alive today because our distant ancestors were successful at reproducing – and the fact many of us have inherited their altruistic tendencies suggests that being altruistic gave them some kind of survival or reproductive advantage.One idea i........

Update on clinical trials and treatments for RCC

by Joana Guedes in BHD Research Blog

Renal cell carcinoma (RCC) is the most common type of kidney cancer and although the majority of cases are sporadic approximately 3% of cases are caused by genetic conditions such as BHD, VHL, HLRCC and TSC (Randall et al., 2014). These inherited forms of RCC have provided great insights into sporadic cancer genetics. BHD patients can develop multiple kidney tumours. In most cases these tumours are small local RCCs that can be surgically removed. However, these treatments are not without risk,........ Read more »

Surgery for "chronic idiopathic constipation" and autism

by Paul Whiteley in Questioning Answers

I can't profess to be an expert on the techniques called sigmoidectomy and appendicostomy so won't even try and pretend that I am. From what I gather from Dr Google, the latter is a surgical technique generally performed to "help deliver enemas more easily" to relieve constipation, whilst the former involves the surgical removal of some or all of the sigmoid colon. Both are only generally indicated when traditional methods of treating constipation for example, fail.The reason I'm briefly ta........ Read more »

Artificial muscle for soft robotics: Low voltage, high hopes

by Dr. Jekyll in Lunatic Laboratories

Soft robots do a lot of things well but they're not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult to store.
