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.

We're more prone to unintentionally plagiarise from others the same sex as us

Look at some of the most high-profile plagiarism scandals, such as Joe Biden's supposed borrowing from Neil Kinnock, novelist Kaavya Viswanathan's "unintentional" plagiarism of Megan McCafferty and Meg Cabot, science writer Jonah Lehrer's lifting words from this blog, and this week, Melania Trump's echoing of phrases used previously by Michelle Obama (though a speech-writer has taken the blame for this).Notice a pattern?In each case, the alleged plagiarists copied others of the same se........

Sensory processing issues are present throughout the autism spectrum

by Paul Whiteley in Questioning Answers

I want to make an initial point about the paper by Corentin Gonthier and colleagues [1] and their research findings titled: 'Sensory Processing in Low-Functioning Adults with Autism Spectrum Disorder: Distinct Sensory Profiles and Their Relationships with Behavioral Dysfunction', I'm not a great fan of the use of the term 'functioning' when it comes to autism. Yes, I know what message it's trying to convey in terms of 'severity' of autism and/or accompanying learning (intellectual) disabili........ Read more »

How Open Access can boost researchers’ careers

Full adoption of open access has not been achieved mainly because researchers are not yet totally convinced that this type of publication will do for their careers the same as the subscription journals.

How our brain puts the world in order

by Dr. Jekyll in Lunatic Laboratories

The world around is complex and changing constantly. To put it in order, we devise categories into which we sort new concepts. To do this we apply different strategies. A team of researchers wanted to find out which areas of the brain regulate these strategies. The results of their study using magnetic resonance imaging (MRI) show that there are indeed particular brain areas, which become active when a certain strategy of categorisation is applied.

Behaviour Problems in Guide Dogs

by CAPB in Companion Animal Psychology Blog

The behavioural reasons why guide dogs sometimes end their working lives early, and what it means for pet dogs.A study by Geoffrey Caron-Lormier (University of Nottingham) et al looks at twenty years of data from Guide Dogs (UK). During this time, 7,770 working guide dogs, who had worked with blind or partially sighted people, were withdrawn from service. By far the most common reason was retirement, which applied to 6,465 dogs (83%). The authors looked at the reasons why other dogs were withdra........ Read more »

The “neighborhood effect” in chromatin biology: TET proteins-mediated DNA demethylation reconfigures the “histone code” at CpG islands

by Li Tan in EpiBeat

A nucleosome is constituted by positively charged histone proteins and negatively charged DNA. Methylation as well as other covalent modifications on DNA and histones ( together also called epigenetic modifications or marks) play important roles in the regulation of chromatin structure and function. TET (Ten-Eleven Translocation) proteins were identified as 5mC oxidases which not only generate new 5mC oxidative derivates (5hmC, 5caC and 5fC) but also initiate active or passive DNA demethylation1........

Take Off Your Coat And Stay Awhile

by Mark Lasbury in As Many Exceptions As Rules

The naked mole rat is quite naked, but a lack of hair does help it move around in its environment. Other mammals that are supposedly hairless aren’t really, even dolphins have a few hairs. Of course, some humans and other mammals can have autoimmune disease mutations that make them completely hairless. For the naked mole rat it was a strange adaptation with strange results – it has become the only cold-blooded (ectothermic) mammal!... Read more »

There's a simple trick to reduce your mind wandering while studying

by BPS Research Digest in BPS Research Digest

It happens to all of us – we're meant to be focused on the page in the book, but our mind is turned inwards thinking about other stuff (Must remember to charge my phone, What time did I say I'd meet Sarah?) Thankfully a new study in Memory and Cognition identifies a straightforward way to reduce how much your mind wanders off topic when you're studying. You just need to ensure the materials you're learning are in your sweet spot – not too easy and not too difficult.For one experiment, Judy X........ Read more »
