Establishing environmental exposures as risk factors for bipolar disorder: Difficult.

by Paul Whiteley in Questioning Answers

The findings reported by Ciro Marangoni and colleagues [1] made for some interesting reading recently and their systematic review of longitudinal studies looking at the various environmental exposures put forward as possible risk factors pertinent to the development of bipolar disorder (BD).Trawling through the peer-reviewed material on this topic, the authors were able to 'clump' the various proposed risk factors into one of three categories: "neurodevelopment (maternal influenza during pr........

Investigating potential fetal exposure to antidepressants

by Dr. Jekyll in Lunatic Laboratories

Depression is a serious issue for expecting mothers. Left untreated, depression could have implications for a fetus’s health. But treating the disease during pregnancy may carry health risks for the developing fetus, which makes an expecting mother’s decision whether to take medication a very difficult one. To better understand how antidepressants affect fetuses during pregnancy, scientists studied exposure in mice.

The RAD-57 – Still Unsafe?

by Rogue Medic in Rogue Medic

I decided to look for something I wrote that I have been wrong about. I thought about Masimo and their RAD-57. I had been very critical of Dr. Michael O’Reilly (then Executive Vice President of Masimo Corporation) for being an advocate of bad science, but he has been hired away by Apple.[1] He should be less dangerous with a telephone than he was with the RAD-57. At the time, he wrote –... Read more »

Parenthood seems to have an opposite effect on how men and women perceive babies' emotions

by BPS Research Digest in BPS Research Digest

In our part of the world, a growing proportion of fathers are rolling up their sleeves and getting involved in early child care. This has prompted increased interest from psychologists in any similarities or differences in the way that mothers and fathers interact with their children. One finding is that fathers tend to engage in more physical play, whereas mothers spend more time playing with toys and interacting socially. A new study in the Quarterly Journal of Experimental Psychology takes a ........ Read more »

Variant viewers are very popular. As we get more and more sequence data, the challenge of looking across many samples only gets more and more important.

Plants That Don’t Sleep Will Take The Dirt Nap

by Mark Lasbury in As Many Exceptions As Rules

If you don't let your plants sleep at night, they die....really! Several species of plants fold their leaves up and reduce their activity at night, every night. If kept from doing that, they turn brown and shrivel up. It's called nyctinasty, and it is different from tropic movements that are directed against specifically positioned stimuli. And what directs their movements? Water! - plants are hydraulic machines.... Read more »

"The average prevalence of ASD [autism spectrum disorder] was 35/10 000 children and was about 4-fold higher in males."I don't have too much to add to the findings reported by Karolina Skonieczna-Żydecka and colleagues [1] who estimated the prevalence of ASD in two regions of Poland: "West Pomeranian and Pomeranian regions."

How Not to Get Killed by a Cow

by Elizabeth Preston in Inkfish



Between 1993 and 2015, cattle killed 13 people who were out for walks in the United Kingdom. Dozens more walkers received broken bones or other injuries from the animals.

Murderous cattle are an understudied phenomenon, say veterinarian Angharad Fraser-Williams and other researchers at the University of Liverpool in the United Kingdom. So they scoured news articles and scientific literature to learn about cattle attacks over two decades. They turned up some advice for people wishing to av........ Read more »

Depressed or inflamed? Inflammation attacks brain’s reward center

by Dr. Jekyll in Lunatic Laboratories

Inflammation is a good thing, it helps the body fight disease, and without it we wouldn't survive. Unfortunately, when inflammation isn't kept under control it can wreak havoc on the body. From potentially causing alzheimer's to arthritis it seems that unchecked inflammation can cause all sorts of issues. In fact, a new study adds to the list of issues out of control inflammation causes in the body.

Weird small holes in the woods

by Rosin Cerate in Rosin Cerate

Within the ground beneath our feet lie dark cavities of various shapes and sizes. They're home to pale and eyeless creatures living a midnight existence. Natural holes in the ground, filled with air and/or water, can be roughly categorized into three types based on the particular habitat they provide for subterranean organisms:(1) Caves are large, deep, and tend not to contain much organic matter for organisms to munch on. They're often found in karst and volcanic areas prone to developing big h........ Read more »

Are ‘predatory’ journals completely negative, or also a sign of something positive?

by SciELO in SciELO in Perspective

Something that is generally, and justifiably, considered negative, can, however, also be a harbinger of an underlying positive development. The case in point is the existence of so-called ‘predatory’ journals, which have – inevitably – emerged in an environment in which a true market for scientific publishing services is slowly taking shape. … Read More →...

Scientific evidence that counting to 10 helps control anger (sometimes)

by BPS Research Digest in BPS Research Digest

It's something we're taught from a young age – when you're about to go into a rage, force yourself to count to ten and hopefully the storm will pass. This may sound like common sense, but without testing the method scientifically, how do we know if and when it really works? For example, while the counting delay could give you a chance to get a grip of your aggressive urges, it's equally plausible that it could give you time to grow even angrier about whatever triggered your displeasure in the ........

Risk of cancer in autism: probably not excessive as more data emerge

by Paul Whiteley in Questioning Answers

A quote to begin: "Taken together, there are no published evidence to suggest that there is a high overall concordance between ASD [autism spectrum disorders] and cancer or between ASD and specific cancers."Those words reported by Svend Erik Mouridsen and colleagues [1] (who knows a thing or two about autism research) should offer some relief to both people on the autism spectrum and their loved ones.Based on the analysis of over 100 adults "diagnosed with infantile autism (IA) in........
