Having recently mentioned the BBC headline that makes up the title of this entry in a related post (see here) I'm pleased to be finally able to bring the paper by Daniel Mackay and colleagues  (open-access) to your attention.Observing that in Scotland at least, "that season of conception is strikingly associated with the subsequent risk of special educational needs in the offspring" there are various potential implications to come from such data covering both learning (intellectual) disabilit........

High-tech prosthetics, computers that are controlled by thought, the ability to walk or even move again, these are just a few of the promises of technology. Unfortunately, while the tech is -- mostly -- up to the challenge, getting the biology side of things to cooperate has been difficult at best, but that could change. Now, scientists have created a material that could make reading biological signals, from heartbeats to brainwaves, much more sensitive.

Using online social media does not lead to long-term problems with our ability to concentrate, according to new research. We are social animals, so it is really no surprise that billions of us now use online tools to communicate, educate and inform each other. The advent of social media and social networking has nevertheless been phenomenally rapid.

"Hypertension in pregnancy was associated with ASD [autism spectrum disorder] in this population even after controlling for known confounders."So said the findings reported by Eileen Curran and colleagues  who, once again (see here), relied on "data from the Millennium Cohort Study" to produce some potentially important information about how adverse pregnancy conditions may/may not impact on offspring behaviour and development.Hypertension (a.k.a high blood pressure) during pre........

Although being first isolated in 1947 from a sentinel rhesus monkey in forests of Uganda, until 2007 Zika Virus (ZIKV) outbreaks have been sporadic, being limited to tropical regions in Africa as well as Southeast Asia and only been associated with relative mild symptoms in about 20% of infected people. Autochthonous transmission of ZIKV outside these areas was only reported in 2007 in the Federal States of Micronesia (FSM), 2013 in French Polynesia, and in 2015 in South America, spreading to th........

New research has demonstrated that a nanoscale device, called a memristor, could be used to power artificial systems that can mimic the human brain. Artificial neural networks (ANNs) exhibit learning abilities and can perform tasks which are difficult for conventional computing systems, such as pattern recognition, on-line learning and classification.

In answer to the question that titles this post on whether parental age differences at offspring conception might matter when it comes to offspring risk of autism or schizophrenia, the answer is very possibly. As the paper by Byars & Boomsma  (open-access) reports: "Our study shows that autistic and schizophrenic disorder risks tend to be higher, in more dissimilarly aged parents, relative to parents with the most similar ages." This age disparity issue has been mentioned previously in th........ Read more »

There are many reports of drug use leading to mental health problems, and we all know of someone having a few too many drinks to cope with a bad day. Many people who are diagnosed with a mental health disorder indulge in drugs, and vice versa. As severity of both increase, problems arise and they become more difficult to treat. But why substance involvement and psychiatric disorders often co-occur is not well understood.

Scientists have discovered a new pathway in the brain that can be manipulated to alleviate depression. The pathway offers a promising new target for developing a drug that could be effective in individuals for whom other antidepressants have failed. New antidepressant options are important because a significant number of patients don't adequately improve with currently available antidepressant drugs.

Honest signalling Theory. Why would animals tell the truth? Is it strong moral fiber? Maybe they paid really close attention when their mother told them the story of the boy who cried wolf? It's actually about self preservation.

A team of scientists are redefining what it means to be a prion--a type of protein that can pass heritable traits from cell to cell by its structure instead of by DNA. Although prions are infamous for causing Creutzfeldt-Jakob disease, fatal familial insomnia, and bovine spongiform encephalopathy, commonly known as mad cow's disease, the present study indicates that prions identified in yeast, and possibly in plants, and other organisms may be beneficial.

Coronal Mass Ejections (CMEs) are hot, massive blobs of plasma and magnetic fields that erupt from the Sun, and are sometimes Earth-directed.

Can we and should we formally 'teach' humour to people diagnosed on the autism spectrum? Indeed, do we actually need to?Yes said the results of the study published by Ching-Lin Wu and colleagues  although I personally am not so impressed.Discussing how their results "supported the effectiveness of the 15-hour training" regime, Wu et al report that for a small group of adolescents diagnosed with an autism spectrum disorder (ASD) "and average intelligence" moves to implement "a humor-knowl........
