Alcoholism as a Reward System Dysfunction

by William Yates, M.D. in Brain Posts

Alcoholism and other addictive behaviors often occur together within individual patients.For example, individuals with alcoholism commonly also are smokers and meet criteria for a diagnosis of nicotine dependence.This co-occurrence suggests multiple types of addiction may share genetic and environmental risk factors. Additionally, there might be a common neurobiological mechanism in play for many addictions.Kenneth Blum and other leading alcoholism researchers recently published a review that pr........

Resourceful Crustaceans Turn Invasive Seaweed into Homes

That’s what tiny crustaceans in the Georgia mudflats have done. Facing an invasive Japanese seaweed, they’ve discovered that it makes excellent shelter, protecting them from all kinds of threats. […]The post Resourceful Crustaceans Turn Invasive Seaweed into Homes appeared first on Inkfish.... Read more »

Fright Week: The Stranger in the Mirror

by The Neurocritic in The Neurocritic

In the mirror we see our physical selves as we truly are, even though the image might not live up to what we want, or what we once were. But we recognize the image as “self”. In rare instances, however, this reality breaks down.In Black Swan, Natalie Portman plays Nina Sayers, a ballerina who auditions for the lead in Swan Lake. The role requires her to dance the part of the innocent White Swan (for which she is well-suited), as well as her evil twin the Black Swan — which is initially out........ Read more »

Pain and adolescent Chronic Fatigue Syndrome

by Paul Whiteley in Questioning Answers

"We found a higher prevalence of severe pain among adolescents with CFS [Chronic Fatigue Syndrome] and lowered pain thresholds compared with HCs [healthy controls]".That was the headline generated by the study from Anette Winger and colleagues [1] (open-access) looking to describe several parameters tied into experience of pain in the context of CFS. Further: "The total sum of bodily symptoms represented a heavy burden with great functional consequences".Your hokey pokey drag........ Read more »

More Genetic Links Behind Autism

by Gabriel in Lunatic Laboratories

Vaccines do NOT cause autism. One more time, vaccines DO NOT cause autism. So what does cause autism, that problem has been plaguing scientists for awhile now. Thankfully two major genetic studies of autism and involving more than 50 laboratories worldwide, have newly implicated dozens of genes in the disorder. The research shows that rare mutations in these genes affect communication networks in the brain and compromise fundamental biological mechanisms that govern whether, when, and how genes ........

If you’ve ever tried to get your kids to share a donut, you understand the importance to dividing things equally (and learning crucial lessons…just buy more donuts next time...I mean, seriously!). Cell division is no different—chromosomes and organelles must all get divided equally. Today’s images are from a paper showing how mitochondria are positioned during cell division in order to allow equal segregation.Many years of research have focused on the equal segregation of chromosomes d........

Yeah, I know, it’s not genomics–but it’s the history of life on this planet–right?  The Paleobiology Database has been keeping records of this ancient biology for a while now, and they have some really nice tools to explore the fossil records and resources that have become available. It’s also interesting to me to see the […]... Read more »

Almost This Or Almost That? Must Be The Other

by Mark Lasbury in As Many Exceptions As Rules

The protists are a catch-all kingdom, neither characteristics nor cladistics can easily group them, or even tell you what one is. Recent studies have begun to identify histories of the plant-like protist phyla based on their flagella. Rhodophyta are a basal phylum, and yet they have no flagella at all, while genomic studies have identified 495 different proteins in chromista flagella, with some being specific to each of the two dissimilar flagella on the organisms. Such diversity within one grou........ Read more »

The stability of an Asperger syndrome diagnosis

by Paul Whiteley in Questioning Answers

"Asperger Syndrome, when considered as an ASD/PDD [autism spectrum disorder/pervasive developmental disorder] diagnosis, was fairly stable into adulthood, but there was a significant increase over time in cases no longer meeting criteria for an ASD diagnosis according to the DSM-IV, or AS according to the Gillberg criteria".The night is darkest just before the dawn.That was one of the primary conclusions made in the paper by Adam Helles and colleagues [1] who prospectively followed a group ........

Scientists resurrect 700-year-old viruses, Just in time for Halloween!

by Gabriel in Lunatic Laboratories

You know how some zombie movies start with a discovery of a virus, it gets loose, and things quickly spiral out of control from that? Well in breaking news a team of researchers have found two 700-year-old viral sequences in frozen caribou dung in an arctic ice patch. The group isolated part of a viral RNA genome and the complete genome of a DNA virus. Then they infected living plants with the DNA virus, what could go wrong?... Read more »

Halloween has put me in the mood to talk about slasher movies. Once I got to looking around, I found more papers on the topic than I thought I would. I gotta warn you, this is a long read, so grab some popcorn and settle in for some slasher movie fun.If you are a fan of horror films then you know Randy Meek’s “Rules that one must abide by to successfully survive a horror movie”: (1) You can never have sex…big no-no, sex equals death, (2) you can never drink or do drugs…it’s the sin-f........

Night Owls Show Increased Alcohol Use Risk

by William Yates, M.D. in Brain Posts

Humans commonly display a circadian rhythm preference for getting up early in the morning or staying up late at night (night owls).This sleep timing, or diurnal preference appears to have genetic contributions.Additionally, diurnal preference may contribute to risk for alcohol consumption as more alcohol is consumed later in the day and during the night time.Nathaniel Watson and colleagues at the University of Washington and the University of Texas recently explored the relationship between diur........
