"In this nationwide sample of live births we observed no association between induction of labor and offspring ASD [autism spectrum disorder] within sibling comparison. Our findings suggest that concern for ASD should not factor into the clinical decision about whether to induce labor."So said the findings reported by Anna Sara Oberg and colleagues  supposedly providing some reassurance to mums-to-be and other groups around the likelihood of offspring autism when birth or l........

If you read my blog often, it's no surprise I suffer from PTSD, depression, and anxiety issues. Maybe it's from my military service, but maybe it's my father's, or his father's, maybe it's an insidious family legacy that was just never noticed. This is because having both parents and grandparents with major depressive disorder (MDD) was associated with higher risk of MDD for grandchildren, which could help identify those who may benefit from early intervention.

Scientists tracked down the evidence for a common statement about bite strength in dogs – and found it lacking.Have you ever read comments about the strength of a dog’s jaw when it bites? These statements are often made in relation to certain types of dog, like pit bulls. Maybe some people take it as fact. But what if it’s not true?A recent paper by Dr. Gary Patronek (Cummings School of Veterinary Medicine, Tufts University) et al traced citations in the literature and went back to the ori........

One cannot over estimate the ways that water affects life on Earth. Beyond its chemical properties, some animals have evolved to substitute water for a rigid skeleton. Hydrostatic skeletons can be used for support, but also as water vascular systems that provide pressure for vascular transport and respiration. A recent review by William H. Kier sheds light on the interactions of different fibers and tissues in water based skeletons. Yet some plants can withstand a loss of 60% of their water, whe........ Read more »

Although research stories stating a link (an association if you will) between condition A and factor X make for interesting reading, not all science is so blessed with such news-worthy findings. That's not to say that 'negative findings' are any less important than the 'hey, we found this...' studies, just that they don't perhaps tend to grab the headlines as much as those finding something.In saying all that I'm standing up for negative findings today and some rather interesting science reporte........

In my previous post, I highlighted a recent study of genetics and major depression from the 23andMe database.I have had a chance to review this manuscript in more detail.

"Comorbid anxiety symptoms are ubiquitous among psychiatric patients with mood or schizophrenia spectrum disorders, and in almost half of them, reportedly severe."So said the findings reported by Karpov and colleagues  who sought to put some further research flesh on to the bones of the idea that clinically relevant anxiety symptoms might not be unstrange bedfellows with a variety of other psychiatric labels.Based on the analysis of various patient groups included in the "Helsinki University ........

In an effort to reduce pain or fix other health problems, some people will submit to having suction temporarily applied to various regions of their skin, usually the neck, shoulders, and back, via a collection of plastic or glass cups.

Pesticides beekeepers are using to improve honeybee health may actually be harming the bees by damaging the bacteria communities in their guts. The discovery is a concern because alterations can affect the gut's ability to metabolize sugars and peptides, processes that are vital for honeybee health.

I tread carefully in discussing the findings reported by Karola Dillenburger and colleagues  (open-access) on the question of "knowledge and training with regards to autism" received by "health, social care, and education staff who work within the statutory autism services sector in the UK." The observation that "an acute lack of autism-specific training that has detrimental impacts" was apparent is a worrying sign indeed.Although not intimately involved in the autism services sector, I ........

Feeling stiff first thing in the morning? It's not your imagination, new research has found a protein created by the body's "biological clock" that actively represses inflammatory pathways within the affected limbs during the night. This protein, called CRYPTOCHROME, has proven anti-inflammatory effects in cultured cells and presents new opportunities for the development of drugs that may be used to treat inflammatory diseases and conditions, such as arthritis.

The idea that use of the diagnostic label called attention-deficit hyperactivity disorder (ADHD) is on the increase, and pretty significantly so, is quite common-place these days (see here).

Long before Zika virus made it a household word, the birth defect called microcephaly puzzled scientists and doctors -- even as it changed the lives of the babies born with it during the pre-Zika era. But new discoveries reported by an international team of scientists may help explain what happens in the developing brains of babies still in the womb, causing them to be born with small brains and heads.

Many lower organisms retain the miraculous ability to regenerate form and function of almost any tissue after injury. Humans share many of our genes with these organisms, but our capacity for regeneration is limited. So scientists are studying the genetics of these organisms to find out how regenerative mechanisms might be activated in humans.
