What if black holes were not... holes? A Los Alamos physicist explains his alternative theory behind these mysterious objects.

by EE Giorgi in CHIMERAS

© Elena E. GiorgiThe concept of a “black hole” — a celestial body so dense and massive that not even light can escape its gravitational field — dates back to the 18th century, with the theoretical work of Pierre-Simon Laplace and John Michell. But it wasn’t until the early 20th century that these mysterious dark objects were first described mathematically by German physicist Karl Schwarzschild. Schwarzschild’s work predicted the existence of a finite distance around the black hole (........ Read more »

Say my name

by Paul Whiteley in Questioning Answers

"At 9 months of age, infants developing ASD [autism spectrum disorder] were more likely to fail to orient to their names, persisting through 24 months."So said the findings reported by Meghan Miller and colleagues [1] investigating an often over-looked but typically informative question relevant to childhood autism screening and assessment: the response to name. Anyone who knows a little about instruments such as the ADOS (Autism Diagnostic Observation Schedule) will already know ........ Read more »

"Autoimmune epilepsy is an underrecognized condition..."

by Paul Whiteley in Questioning Answers

"Among adult patients with epilepsy of unknown etiology, a significant minority had detectable serum Abs [autoantibodies] suggesting an autoimmune etiology."So said the findings reported by Divyanshu Dubey and colleagues [1] continuing a research theme previously discussed on this blog (see here) on how epilepsy / seizure-type disorder(s) for some might have more to do with immune function than many people might think.OK, a brief bit of background: epilepsy is a blanket term cover........

The Function of Play Bows in Dog and Wolf Puppies

by CAPB in Companion Animal Psychology Blog

New research casts doubt on an old explanation for the play bow – and suggests it’s all about more play.The play bow is a glorious signal in dogs. The bum goes up and the elbows go down, leaving the rear end sticking up, usually accompanied by a lovely happy face (as pictured above). Not just reserved for other dogs, our canine friends will play bow to us too.Traditionally, it was believed that the play bow serves as a signal to say something like, “I’m just playing, it’s not real!”,........

History of bipolar disorder = elevated risk of dementia: is vitamin D important?

by Paul Whiteley in Questioning Answers

"History of BD [bipolar disorder] is associated with significantly higher risk of dementia in older adults."So said the systematic review and meta-analysis published by Breno Diniz and colleagues [1] taking in the accumulated peer-reviewed literature on this topic. Including data for some 3000 individuals diagnosed with bipolar disorder and nearly 200,000 controls (without bipolar disorder), authors calculated something of a significantly higher risk of dementia in those with a do........

Do twitter or facebook activity influence scientific impact?

by Richard Kunert in Brain's Idea

Are scientists smart when they promote their work on social media? Isn’t this a waste of time, time which could better be spent in the lab running experiments? No. An analysis of all available articles published by PLoS journals suggests otherwise. My own twitter activity might best be thought of as learning about science (in […]... Read more »

Neuropsychiatric disorder onset "temporally related to prior vaccinations"?

This Squid Gives Better Side-Eye Than You

by Elizabeth Preston in Inkfish



Yes, this cephalopod is looking at you funny. It's a kind of cockeyed squid—an animal that looks like some jokester misassembled a Mr. Potato Head. One of the cockeyed squid's eyes is big, bulging and yellow. The other is flat and beady. After studying more than 25 years' worth of undersea video footage, scientists think they know why.

The Monterey Bay Aquarium Research Institute (MBARI) in California has been dropping robotic submarines into the ocean for decades. The footage from th........ Read more »

The Science of the Rorschach Blots

by Neuroskeptic in Neuroskeptic_Discover

When the psychiatrist Hermann Rorschach blotted ink onto paper to produce a series of abstract patterns, could he have known that nearly 100 years later, the Rorschach test would be a household name?



Although the use of the Rorschach to diagnose mental illness is mostly a thing of the past, research on the test continues. Last week, two new papers were published on the Rorschach blots, including a fractal analysis of the images themselves and a brain scanning study using fMRI.

Catatonic symptoms and autism

by Paul Whiteley in Questioning Answers

"Catatonic symptoms are more prevalent in young people with autism than previously thought" said the article recently published by Breen and Hare [1]. Continuing a research theme of at least one of the authors [2], the idea that catatonic symptoms - primarily manifesting as stupor, unresponsiveness to light, noise or touch, mutism, etc - might be over-represented when it comes to autism is not a new one by any means.Breen & Hare set about looking for "the presence and nature of such att........

Using Discourse Analysis to Assess Cognitive Decline

by The Neurocritic in The Neurocritic

Figure from Gauthier et al. (2005).

Alzheimer's Disease (AD) and other dementias are progressive neurodegenerative conditions that unfold over time. Subtle symptoms such as forgetfulness and word finding problems may progress to mild cognitive impairment (MCI), and then escalate to full-blown dementia. Recent efforts to classify prodromal states have included automated analysis of spontaneous... Read more »

Social interaction and autism: it takes two to tango

by Paul Whiteley in Questioning Answers

Psychology experiments are not generally fodder for this blog when it comes to autism. The main reason being that quite a few appearing in the peer-reviewed literature tend to look at quite abstract features perhaps somewhat removed from the daily lives of autistic people and their significant others. A few also seem to struggle with the idea that grand over-arching psychological theories (that seem to inevitably follow psychological findings in particular) are not required when it comes to auti........
