Simple Jury Persuasion: Should you consider 3-D for your courtroom videos?

by Doug Keene in The Jury Room

Evidence admissibility issues aside, the answer is, “only if you can do it as well as they did in the 3D movie Polar Express”. As it turns out, 3D isn’t that much more impactful than 2D unless it’s done really, really well. Psychologists and neuroscientists studying emotion often use film clips for their research. So […]

Term vs. preterm birth and the presentation of autism

by Paul Whiteley in Questioning Answers

The paper by Katherine Bowers and colleagues [1] continues the interest in the concept of 'the autisms' with their observations on the presentation of autism (and its comorbidities) when looking at those "born preterm versus those born at term".We'd better get back, 'cause it'll be dark soon, and they mostly come at night... mostlyBased on an analysis of quite a healthy participant number heading up to 900 "males and females with autism spectrum disorder", authors reported on several phenotypic ........

The Genetic Evolutionary Arms Race

by Gabriel in Lunatic Laboratories

Genes are tricky little buggers, the stuff that makes us up has fought the test of time to make it to where we are today. It is thought that our genes changed in an attempt to outpace other life, albeit random changes.That might only be half right however, new findings suggest that there is an evolutionary arms race going on within the genome against, of all things, itself. This inherent competition of primates drove the evolution of complex regulatory networks that orchestrate the activity of ........ Read more »

Numbers on a scale: How bad did you say your pain was?

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

Have you ever been asked to give your pain rating on a scale of 0 – 10 (where 0 = no pain at all and 10 = most extreme pain you can imagine)? Have you ever tried to work out whether today’s pain is worse than yesterdays? What does a pain rating tell us?... Read more »

How to Look for Pine Marten

by Denise O'Meara in Denise O'Meara

The pine marten (Martes martes) is one of Ireland’s most beautiful but elusive mammals. It is notoriously difficult to see as it tends to be mostly nocturnal, and is a naturally shy animal. It is about the size of a cat, and in Irish it is actually called the tree cat (cat crainn). The species historically suffered massive population declines due to forest removal in the 16th Century and pine marten were also trapped and killed for their fur, which was worn by the nobility across Europe.

Sometimes choices are not thought out

by Janet Kwasniak in Neuro-patch

In some competitive situations animals can produce random behavior rather than behavior based on prior experience. The anterior cingulate cortex is where strategies based on models of reality and history are generated; switching to random behavior is done by inputs to this part of the brain from the locus coeruleus. This was reported in a […]... Read more »

Are Black Holes just in Our Imagination?!

by Gabriel in Lunatic Laboratories

Black holes, physicists have been fighting over them forever, heck there is even a book entitled the black hole war! (which I do recommend for anyone interested) It’s no real surprise since they are the ultimate unknown – the blackest and most dense objects in the universe that do not even let light escape. And as if they weren't bizarre enough to begin with, now add this to the mix: they don’t exist.... Read more »

Yes, people with autism do have headaches

by Paul Whiteley in Questioning Answers

I don't mean to be haughty but a sentence included in the paper by Victorio [1] led to the title of today's very quick post. Based on a chart review of patients diagnosed with an autism spectrum disorder (ASD) attending a neurology clinic, the author concluded that "ASD patients, despite being known to have indifference to pain, can experience headaches".Pain is something which has cropped up quite a bit in the autism research arena and has appeared more than once on this blog (see here and see ........

“GMO” Foods (Once Again) Proven Safe

by Gabriel in Lunatic Laboratories

GMO, I shudder every time I hear someone talk about the “dangers”. It’s one of the new buzzwords that doesn’t actually mean anything, but still manages to scare people. Well a new scientific review reports that the performance and health of food-producing animals consuming genetically engineered feed, first introduced 18 years ago, has been comparable to that of animals consuming non-GE feed. Not that this will stop people from spreading fear, but it’s a start.... Read more »

Walking Really Is Just Falling and Catching Yourself

by Elizabeth Preston in Inkfish

The flailing of a gymnast who’s missed a step on the balance beam might not be far off from what the rest of us experience every day. Each step we take is really a tiny fall, a mathematical model suggests. The random-looking variation in our footfalls is actually a series of corrections. Our strides are […]The post Walking Really Is Just Falling and Catching Yourself appeared first on Inkfish.... Read more »

Anthropomorphic Neuroscience Driven by Researchers with Large TPJs

by The Neurocritic in The Neurocritic

For immediate release — SEPTEMBER 26, 2014Research from the UCL lab of Professor Geraint Rees has proven that the recent craze for suggesting that rats have “regrets” or show “disappointment” is solely due to the size of the left temporal-parietal junction (TPJ) in the human authors of those papers (Cullen et al., 2014). This startling breakthrough was part of a larger effort to associate every known personality trait, political attitude, and individual difference with the size of a un........ Read more »

Breaking Research: Fruit flies provide insights into metabolism and how we age

by Bethany Christmann in Fly on the Wall

Why do we age? It’s more than just a philosophical question; it’s a puzzle that has frustrated scientists for decades. Currently, the most accepted hypothesis is that aging is the result of accumulated damage to our cells during our lifetime. “Accumulated damage” encompasses a variety of things that can go wrong, including DNA mutations, problems […]...

Would you prefer a smaller government? Actually, no you would not. 

by Rita Handrich in The Jury Room

For a number of years now, we have been asking our mock jurors what role they think government should play in our society and giving them a number of options among which to choose. Most of them say government should play a smaller role and we certainly have all heard the media messages that tell us […]

by Erin Campbell in HighMag Blog

While taking an awesome cell biology course in college, I was coming to terms with my mother’s recent ovarian cancer diagnosis. The scientist in my head couldn’t shake the curiosity about how my mother’s cells could have betrayed her so royally. This intersection of basic cell biology and cancer kick-started my interest in cell biology research. Today’s image is from a paper showing a role for the ARF tumor suppressor in maintaining chromosomal stability. THIS paper is one of the mil........ Read more »

A New Discovery in the Treatment of Autoimmunity and Chronic Inflammation

by Gabriel in Lunatic Laboratories

Lupus, Type 1 diabetes, and multiple sclerosis are all diseases brought on by autoimmunity — the bodies inability to tell itself apart from foreign invaders. Finding a cure, or even a suitable treatment has been to put it gently a long, painful road, with little to show for it. On the forefront of the war against the body betrayal is immunosuppressants, which with them carry their own set of side effects and in most cases only off mild to moderate relief of symptoms. But that is all changing a........ Read more »
