Stereotypes, rudeness, sleepy (and punitive) judges,  assumptions and freak airplane accidents

Time for another combination post of various things you will want to know that will improve your conversation skills and general life knowledge. We are not saying that it will make your hair shiny or inspire your kids to do their homework. Kernels of wisdom, that’s what they are, in truth. Talking to your kids […]... Read more »

Poverty status and autism, ADHD and asthma

by Paul Whiteley in Questioning Answers

The paper by Christian Pulcini and colleagues [1] talking about poverty status potentially influencing "parent-reported lifetime prevalence and comorbidities" when it comes to three target conditions (autism, attention-deficit hyperactivity disorder [ADHD] and asthma) should have been a call to action. Concluding that "poor and near poor children had a higher lifetime prevalence of asthma and ADHD, but not ASD [autism spectrum disorder]" [2], some of the findings have instead attracted crit........

Improving Hearing-Aid Access in Older Adults

by William Yates, M.D. in Brain Posts

There are significant barriers to widespread use of hearing-aids in older adults with age-related hearing loss.Sensitivity to the stigma of wearing a hearing-aid is one barrier.Cost is another significant barrier. In the U.S., bilateral hearing-aid purchase amounts to a cost of $2400 to $5800. This cost is typically not covered by Medicare or other health insurance plans.I ran into a interesting manuscript on looking at an alternative less costlier approach to hearing-aid selection and purchase.........

Subgroups in autism (without intellectual disability)

by Paul Whiteley in Questioning Answers

"Children with ASD [autism spectrum disorder] without ID [intellectual disability] could be differentiated into Moderate and Severe Social Impairment subgroups when core ASD symptoms were more closely examined."So said the findings reported by Felicity Klopper and colleagues [1] looking at an important part of the autism research scene related to the 'plurality' of the term autism and the seemingly vast range of presentations included under the label. Reliant on data obtained........ Read more »

What kind of scratching post do cats prefer?

by CAPB in Companion Animal Psychology Blog

It’s important to provide cats with the right kind of scratching post – and reward them for using it.Inappropriate scratching is a fairly common complaint about cats. That’s inappropriate from the owner’s perspective, because from the cat’s point of view they are just doing what comes naturally. Research by Colleen Wilson DVM et al tells us what kind of scratching post to provide in order to keep both cat and owner happy.Cats scratch in order to mark their territory. It leaves a visual........ Read more »

Politics Trump Healthcare Information: News Coverage of the Affordable Care Act

by Jalees Rehman in The Next Regeneration

Gollust and colleagues found that 55% of the news stories either focused on the politics of the ACA such as political disagreements over its implementation (26.5%) or combined information regarding its politics with information on how it would affect healthcare insurance options (28.6%). Only 45% of the news stories focused exclusively on the healthcare insurance options provided by the law. The politics-focused news stories were also more likely to refer to the law as “Obamacare” wh........ Read more »

Transient Imprinting of Genes in the Human Placenta

by Marta Sanchez Delgado in EpiBeat

When the fertilization occurs, the maternal and paternal pronuclei have thousands of opposite methylated regions. Most of this germline methylation are resolved during the postfertilization epigenetic reprogramming by active mechanism for the sperm-derived methylated regions and depending on DNA replication for the oocyte-derived ones. There is a subset of regions that are known to avoid this demethylation: the imprinted differentially methylated regions (DMRs). The imprinted DMRs are in general........ Read more »

So maybe it doesn’t pay to be beautiful  

by Doug Keene in The Jury Room

Or at least, maybe there is no “ugliness penalty” if you are not beautiful. We’ve written a number of times here about the many benefits given to those who are seen as beautiful or attractive. This paper debunks the stereotype and says that salary goes beyond appearance and individual differences matter too. The researchers used […]... Read more »

Sex and age might affect comorbidity profiles in autism

by Paul Whiteley in Questioning Answers

The paper by Supekar and colleagues [1] provides some food for thought today specifically with the idea that comorbidity profiles accompanying autism might be influenced by age and gender in mind.To quote: "These results highlight crucial differences between cross-sectional comorbidity patterns and their interactions with sex and age, which may aid in the development of effective sex- and age-specific diagnostic/treatment strategies for ASD [autism spectrum disorder] and comorbid condi........

The slowing down of the biggest scientific journal

by Richard Kunert in Brain's Idea

PLoS ONE started 11 years ago to disruptively change scholarly publishing. By now it is the biggest scientific journal out there. Why has it become so slow?

Neurofeedback Training For Insomnia No Better Than Sham

by The Neurocritic in The Neurocritic





Neurofeedback training (NFT) is a procedure that tries to shape a participant's pattern of brain activity by providing real-time feedback, often in the form of a video game combined with other sensory stimuli that provide rewards when the “correct” state is achieved. The most common form of NFT uses EEG (brainwave) activity recorded non-invasively from the scalp. The EEG is a complex mixture

Now, as February runs out, it’s time to reflect on the 15 non cancer-specific posts from last year. Although, as we’ll see, some of them are still related to mathematical oncology. With a […]...

A Weekend Camping Trip Is Enough to Reset Your Internal Clock

by Elizabeth Preston in Inkfish



Humans have been fighting our internal clocks ever since we invented sitting around a campfire. We have powerful natural rhythms that keep us on a 24-hour cycle; if you've ever been steamrollered by jet lag after an intercontinental flight, you know how powerful those rhythms are. But we muffle them with caffeine, alarm clocks, and electric lights. It's easy to undo the damage, though. One weekend of camping can do the trick—and it'll even cure your case of the Mondays.



In 2013, rese........ Read more »

Outcome in Early Education Interventions (Educare)

by William Yates, M.D. in Brain Posts

Despite centuries of experience in education, the best time to start formal education is still under debate. Is five years of age too old? Is three years of age too early?One issue with early education interventions is the potential for catch-up in children starting school later. In other words, early gains with younger children may evaporate overtime.One recent research study examines effectiveness of a child development intervention known as Educare. Educare seeks to reduce the achievement gap........ Read more »

Quasi-periodic acceleration of electrons in the flare on 2012 July 19 by Jing Huang et al.*

We study the quasi-periodic pulsations (QPPs) of nonthermal emission in an M7.7 class flare on 2012 July 19 with spatially resolved observations at microwave and HXR bands and with spectral observations at decimetric, metric waves. Microwave emission at 17 GHz of two footpoints, HXR emission at 20–50 keV of the north footpoint and loop top, and type III bursts at 0.7–3 GHz show prominent in-phase oscillations at 270$\,$s. Through the [...]... Read more »

Premature mortality in intellectual disability in Australia (and England)

Know your brain: Mammillary bodies

by neurosci in Neuroscientifically Challenged

Where are the mammillary bodies?























The mammillary bodies are part of the diencephalon, which is a collection of structures found between the brainstem and cerebrum. The diencephalon includes the hypothalamus, and the mammillary bodies are found on the inferior surface of the hypothalamus (the side of the hypothalamus that is closer to the brainstem). The mam........ Read more »
