Anxiety and sensory over-responsivity linked to gut issues in autism

by Paul Whiteley in Questioning Answers

"The name's Lonnegan! Doyle Lonnegan!"Consider this micropost an extension of some previous discussions on this blog about how gastrointestinal (GI) issues present in cases of autism might show some connection to the presence of anxiety and sensory issues (see here). Today I'm discussing further research by Micah Mazurek and colleagues [1] which follows a previous publication by this author [2] on this topic.In the latest paper, Dr Mazurek and colleagues describe the course of abdominal pain in ........

Why are ethical standards higher in science than in business and media?

by Richard Kunert in Brain's Idea

Facebook manipulates user content in the name of science? Scandalous! It manipulates user content in the name of profit? No worries! Want to run a Milgram study these days? Get bashed by your local ethics committee! Want to show it on TV? No worries. Why do projects which seek knowledge have higher ethical standards than […]... Read more »

by Erin Campbell in HighMag Blog

All good things must end—even the focal adhesions that are so key to cell migration. Today’s notable image is the first live cell visualization of ECM degradation at focal adhesions, in a recent paper that reports the link between CLASPs, exocytosis, and focal adhesion turnover. Cell migration depends on the precisely-timed formation of focal adhesions (FAs) that link the crawling cell to the extracellular matrix (ECM). FAs serve as anchor points for the crawling cell, yet must later di........ Read more »

Biofilms: Using Bacteria for new Designer Nanomaterials

by Gabriel in Lunatic Laboratories

For most people biofilms conjure up images of slippery stones in a streambed and dirty drains. While there are plenty of "bad" biofilms around – they are even the same stuff that causes pesky dental plaque and a host of other more serious medical problems – a team of researchers sees biofilms as a robust new platform for designer nanomaterials that could clean up polluted rivers, manufacture pharmaceutical products, fabricate new textiles, and more....

Live Fast, Die Young: Evolutionary Outcomes of an Asteroid Impact

by Melissa Chernick in Science Storiented

A new semester has started and with it an influx of new students into the lab has begun. Busy has become my middle name. So when I was looking around for a paper to write about I wanted something different and cool. Not exactly hard to find in science. The asteroid known as 2012 DA14 will narrowly miss Earth this Friday, the closest known asteroid flyby on record. And by close we’re talking within the orbits of many communications satellites. This got me thinking about and looking for recent p........ Read more »

Antidepressants Modulate Memory in the Healthy Brain

by William Yates, M.D. in Brain Posts

The mechanism of antidepressant drug response is not well understood.One theory posits antidepressant effects are only seen in those with clinical depression leaving the healthy brain unchanged.In a previous post, I outlined a study demonstrating effects of antidepressants on brain connectivity measures in the healthy brain.A recent fMRI study extends our understanding of the potential mechanisms for antidepressant drugs.CT Cerqueira and colleagues from Brazil studied the effects of the antidepr........

Does Your Cat Sniff New Food?

by CAPB in Companion Animal Psychology Blog

New research investigates which feline behaviours show that cats find food tasty. Photo: FreeBirdPhotos / ShutterstockThere are certain things we can take for granted when feeding the cat: the pitiful miaows that become increasingly strident, the anticipatory purring when you move towards the cat food, and the way the cat wraps herself around your leg as if you’re her best friend ever. But when you put the food down, is there any guarantee she will eat it? Cat food manufacturers have team........ Read more »

Builders and Blocks – Engineering Blood Vessels with Stem Cells

by Jalees Rehman in The Next Regeneration

Back in 2001, when we first began studying how regenerative cells (stem cells or more mature progenitor cells) enhance blood vessel growth, our group as well as many of our colleagues focused on one specific type of blood vessel: arteries. Arteries are responsible for supplying oxygen to all organs and tissues of the body and arteries are more likely to develop gradual plaque build-up (atherosclerosis) than veins or networks of smaller blood vessels (capillaries). Once the amount of plaque in an........ Read more »

Should I Stay Or Should I Go

by Mark Lasbury in As Many Exceptions As Rules

Bacteria can swarm to conquer new territory or settle into structured biofilms, not unlike tribes that are nomadic versus those that build cities. New research indicates has shed light on the mechanics of swarming and biofilm production, including the function of extracellular DNA and secreted polysaccharides. Both biofilms and swarming depend on quorum sensing, and several new papers have identified chemicals that can interrupt quorum sensing in pathogenic bacteria and therefore prevent disease........

The Disgust Scale: How have we missed this all this time?

by Rita Handrich in The Jury Room

We’ve covered a lot of the disgust research so it is curious to us that somehow we missed sharing the actual Disgust Scale with you earlier. The Disgust Scale was developed by the infamous Jonathan Haidt (his surname is pronounced “height”) back in 1994 before disgust was considered cool. In brief, the Disgust Scale was […]

Autoimmune disease risk and eating disorders

Our findings support the link between immune-mediated mechanisms and development of eating disorders".So said the paper by Anu Raevuori and colleagues [1] (open-access) based on an analysis of over 2300 people "treated at the Eating Disorder Unit of Helsinki University Central Hospital between 1995 and 2010" compared with nea........

Not So Competitive Return Rates to Activity Following ACL Reconstruction

by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field

Only 55% of athletes returned to competitive sport following anterior cruciate ligament (ACL) reconstruction. The debate continues as to whether hamstring or patellar tendon autograft is better. However, factors that may favor return to competitive sport include younger age, male gender, elite sport, and a positive psychological response. ... Read more »
