DICE 2014

by Marco Frasca in The Gauge Connection

I have spent this week in Castiglioncello participating to the Conference DICE 2014. This Conference is organized with a cadence of two years with the main efforts due to Thomas Elze. I have been a participant to the 2006 edition where I gave a talk about decoherence and thermodynamic limit (see here and here). This […]... Read more »

Move over Carbon nanotubes introducing Diamond nanothreads

by Gabriel in Lunatic Laboratories

Carbon nanotubes, the wave of the future. Our hopes and dreams for the future have been firmly placed in using the unique material for everything from electronics to engineering. Unfortunately the production of carbon nanotubes has been hampered by setbacks, which as it turns out might not be a bad thing. This is because for the first time, scientists have discovered how to produce ultra-thin “diamond nanothreads” that promise extraordinary properties, including strength and stiffness greate........

Warning: This Post Will Change Your Brain

by Neuroskeptic in Neuroskeptic_Discover

Last week I gave a talk in Brazil called Why Is It So Hard To Think About The Brain?, Well, no sooner have I returned than a story appeared that illustrates my point all too well. A neuroscience paper made headlines around the world on Friday. Here’s Time‘s take: One Dose of Antidepressant Changes the […]The post Warning: This Post Will Change Your Brain appeared first on Neuroskeptic.... Read more »

Lengthen Telomeres and Turn Back Aging

by Gabriel in Lunatic Laboratories

Want to live longer and healthier? Of course you do, well science may just have the answer! Scientists have discovered an on-and-off "switch" in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age. Getting cells to divide might not be that hard (or even very useful), but that isn't all, it gets better!... Read more »

Antibiotics and risk of pediatric Crohn's disease

by Paul Whiteley in Questioning Answers

I couldn't let the meta-analysis from Ryan Ungaro and colleagues [1] pass without a brief mention. Concluding that: "Exposure to antibiotics appears to increase the odds of being newly diagnosed with CD [Crohn's disease] but not UC [ulcerative colitis]" and further: "This risk is most marked in children diagnosed with CD", the implications from this and other findings in this area may be far-reaching.I've talked before on this blog about antibiotic exposure and risk of inflam........

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 »

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?

MERS-CoV is the causative agent of a severe and fatal respiratory illness in humans with no known effective antiviral therapy or vaccine. Although MERS-CoV infections have been reported from countries outside the Arabian peninsula, local transmission with the exception of family cluster of three cases in Tunisia (with the index case being infected in the KSA) has been limited to the Kingdom of Saudi Arabia, the Kingdom of Jordan, Qatar, Oman, and the United Arab Emirates.
