Horror paradox

by Donders in Donders Wonders

Halloween is een feest dat in Nederland steeds populairder lijkt te worden. Deze tijd van het jaar komen er altijd veel horrorfilms uit waar we ons graag bang door laten maken. Maar is dat niet een beetje gek? Bang zijn is toch helemaal niet leuk? Wat vertelt de wetenschap ons over deze paradox? Afbeelding door […]... Read more »

Friendly, conscientious people are more prone to "destructive obedience"

by BPS Research Digest in BPS Research Digest

In Milgram's shock experiments, a surprising number of people obeyed a scientist's instruction to deliver dangerous electric shocks to another person. This is usually interpreted in terms of the power of "strong situations". The scenario, complete with lab apparatus and scientist in grey coat, was so compelling that many people's usual behavioural tendencies were overcome.But a new study challenges this account. Recognising that many participants in fact showed disobedience to the scientist in M........ Read more »

Electron Paramagnetic Resonance of hair!

by mrsitandspin in Sit and Spin

I wanted to switch gears a bit and do a paper on Electron Paramagnetic Resonance (EPR), also know as Electron Spin Resonance (ESR). The paper for this weeks is

Electron spin resonance (ESR/EPR) of free radicals observed in human red hair: a new, simple empirical method of determination of pheomelanin/eumelanin ratio in hair.

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 ........

by Erin Campbell in HighMag Blog

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........

Dopamine signaling leads to loss of polycomb repression and aberrant gene activation in experimental parkinsonism

by EpiBeat in EpiBeat

Parkinson’s disease (PD) is the second most frequent neurodegenerative disease, affecting 1-2% of the population over 55 years of age. The main pathological feature of PD is the progressive death of neurons located in the midbrain that produce the neurotransmitter dopamine.  These neurons modulate the activity of a collection of ...

Video Tip of the Week: PaleoBioDB, for your paleobiology searches

by Mary in OpenHelix

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 »

How to Improve Internet Comments

The most promising and yet most disappointing aspects of the Internet are the written comments left by the general public.  On one hand, comment sections are a great democratization of personal opinion.  With public commenting, anyone can make their opinion known until the world on whatever topic interests them.  On the other hand, comment sections give voice to absolutely […]The post How to Improve Internet Comments appeared first on NeoAcademic.Related articles from NeoAcademic:Us........

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 »

Is that eye witness lying? Let’s just check those P300 brain waves…

by Rita Handrich in The Jury Room

We’ve written before about the inaccuracy of eye witness testimony despite the familiarity of the saying, “I know what I saw!”. But here is newly published research purporting to have been “able to discriminate perfectly between 12 knowledgeable subjects who viewed stimuli related to their activities and 12 non-knowledgeable subjects who viewed only irrelevant items”.

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 »

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........
