Nanosponges Clean up Antibody-mediated Autoimmune Disease

by Gabriel in Lunatic Laboratories

What does lupus, rheumatoid arthritis, type I diabetes, multiple sclerosis, and rheumatic heart disease have in common? All of these (and many other) apparently unrelated disorders are caused by autoimmunity, in which the immune system produces antibodies that attack normal, healthy cells and tissues. Currently considered incurable, these autoimmune diseases can be managed, but to varying degrees and not without serious side effects. Moreover, autoimmune diseases include a wide range of dysfunct........ Read more »

Estimating how much we don't know

by Iddo Friedberg in Byte Size Biology

Most of our understanding of what genes do comes from computational predictions, rather than actual experiments. For almost any given gene that is sequenced, its function is determined by putting its sequence through one or more function annotation algorithms. Computational annotation is cheaper and more feasible than cloning, translating, and assaying the gene product (typically a protein) to find out exactly what it does. Experiments can be long, expensive and, in many cases, impossible to pe........ Read more »

New test for Diagnosing Alzheimer’s Early

by Gabriel in Lunatic Laboratories

Alzheimer’s diagnosis is important, like the famous slogan “with a stroke, time lost is brain lost,” detecting alzheimer’s is important in order to stave off cognitive decline. A just like a stroke time lost is brain lost. Unfortunately early diagnosis has been hard to come by, but now researchers say a simple test that combines thinking and movement can help to detect heightened risk for developing Alzheimer’s disease in a person. The best part, they say this will work even before the........ Read more »

Translational Findings: What drunk fruit flies can tell us about alcohol addiction

by Bethany Christmann in Fly on the Wall

A study in 2012 found that approximately 7.2% of adults in the United States have an alcohol use disorder (a term that covers any person for whom their drinking causes distress or harm). That adds up to approximately 17 million Americans! Treatments for alcoholism, such as behavioral therapies or medications, can often be ineffective in […]... Read more »

Air travel may cause pneumothorax in BHD patients

by Lizzie Perdeaux in BHD Research Blog

One concern many BHD patients have is whether it is safe to take commercial flights, or whether this would increase the chances of a pneumothorax. A recently published study, by Professor Pieter Postmus and his team at the VU Medical … Continue reading →... Read more »

Increasing parental age and autism severity?

by Paul Whiteley in Questioning Answers

An interesting paper by David Geier and colleagues [1] (open-access here) caught my eye recently, concluding that there was a lack of support for the suggestion that: "increasing parental age was associated with increasing autism spectrum disorder phenotypic severity"."the snozzberries taste like snozzberries".Before progressing through the paper and its possible implications, the eagle-eyed out there might have already spotted the name Dr Brian Hooker on the authorship list of the Geier paper. ........

The neuroscience behind scratching an itch

by William Lu in The Quantum Lobe Chronicles

The beautiful experience of alleviating an itch, the vigorous scratching of skin cells, and the white flakes that float away slowly and gently like a whimsical dream.If only those with chronic itching problems could describe their conditions in such a serene way. In the latest edition of Nature Neuroscience, Diana Bautista and colleagues (2014) review the literature on the underlying mechanism of the itch at the molecular and cellular level within the peripheral and central nervous systems. They........ Read more »

Experimental and comparative oncology: zebrafish, dogs, elephants

by Artem Kaznatcheev in Evolutionary Games Group

One of the exciting things about mathematical oncology is that thinking about cancer often forces me to leave my comfortable arm-chair and look at some actually data. No matter how much I advocate for the merits of heuristic modeling, when it comes to cancer, data-agnostic models take second stage to data-rich modeling. This close relationship […]... Read more »

How to Look for Otters

by Denise O'Meara in Denise O'Meara

In the first of a new series of posts about “How to Look for Mammals”, I take a look at one of our semi aquatic species, the Eurasian otter. The Eurasian otter is distributed across Europe and into Eurasia, but it is absent and restricted to small isolated pockets in some European countries. However, the species is slowly starting to recover across Western Europe. Ireland is a stronghold for the otter, and marks the western most point of the otter’s distribution. It is thought........

Coffee Drinkers Have Trouble Talking About Emotions?

by Neuroskeptic in Neuroskeptic_Discover

People who drink a lot of coffee – and other caffeinated beverages – find it more difficult to identify and describe their own emotions.

Is Stress Eating Away at You? No, Literally…

by Gabriel in Lunatic Laboratories

Ever wonder why, when people are too stressed, they are often grouchy, grumpy, nasty, distracted or forgetful? It may not be something you’ve done, in fact it turns out stress is literally tearing apart the brain. By this I mean that researchers have just highlighted a fundamental synaptic mechanism that explains the relationship between chronic stress and the loss of social skills and cognitive impairment. When triggered by stress, an enzyme attacks a synaptic regulatory molecule in the brain........ Read more »

There's a problem with assuming the most intelligent candidates make the best employees

by BPS Research Digest in BPS Research Digest

Workplace research through the 20th Century suggested that selecting for intelligence is the best way to identify good performers. General mental ability (GMA), a popular recruitment measure that maps closely to the colloquial meaning of "intelligence", is strongly correlated with on-the job performance, well ahead of any other single measure.This consistent finding came from studies that mostly defined job performance as carrying out the duties expected in that role. Although intuitive, this ne........ Read more »

Genetics of Social Skills: Oxytocin Receptor Gene

by William Yates, M.D. in Brain Posts

Social neuroscience is an emerging emphasis in the field of neuroscience research.Social cognition is the subset of cognitive functions related to social processes and includes factors such as facial recognition, social memory and ability to form friendships and other social bonds.Impairment in social cognition is a known feature in autism, schizophrenia and other mental disorders. This type of impairment can produce significant problems in life adjustment, employment and human attachment.Geneti........ Read more »

Pythons and the Land - The Bangladesh Python Project Part IV --Guest Post--

by David Steen in Living Alongside Wildlife

By Jon Hakim

Make sure to start at Part I.

“Snake call!  It's the python.  Are you up?  We got a call for the python.”









The words were almost the same, but I woke up to see that
Caesar's face held a grimace.  The
call he feared had come. 






Let's back up to the night before.



In the last post I left you in a moment of triumph.  Kanai had led four of us right to our

Why is poverty associated with mental health problems for some people, but not others?

by BPS Research Digest in BPS Research Digest

By guest blogger Peter Kinderman“I’ve been rich and I’ve been poor. Believe me, rich is better” (Mae West).  Critiques of the rather discredited "disease-model" of mental illness are commonplace, but we also need to articulate the alternative. New research by Sophie Wickham and colleagues helps do that, by providing support for the idea that we learn, as a consequence of our experiences in life, a framework of appraising, understanding and responding to new challenges. This psy........ Read more »
