Friday Fellow: Common Stonewort

by Piter Boll in Earthling Nature

by Piter Kehoma Boll It’s always hard to introduce a less charismatic species here. Not because they are less interesting to me, but because I cannot find good information available. But I try to do my best to show all … Continue reading →... Read more »

Non-febrile seizures in children with autism vs unaffected siblings

by Paul Whiteley in Questioning Answers

"Children with idiopathic ASD [autism spectrum disorder] are significantly more likely to have non-febrile seizures than their unaffected siblings, suggesting that non-febrile seizures may be ASD-specific."So said the findings from Lena McCue and colleagues [1] (open-access) continuing a research theme looking at one of the important 'comorbidities' that seems to be over-represented when it comes to a diagnosis of autism (see here). Idiopathic autism or ASD refers to autism as the........ Read more »

ADHD, not autism, might count when it comes to 'comorbid psychiatric symptomatology'

by Paul Whiteley in Questioning Answers

A quote to begin this fairly brief post: "Our study concluded that higher levels of ADHD [attention-deficit hyperactivity disorder] severity-not ASD [autism spectrum disorder] severity-were associated with a higher prevalence of comorbid psychiatric symptomatology in school-age children with ASD. These findings may encourage clinicians to thoroughly assess ADHD symptomatology in ASD children to better inform treatment planning."That was the research bottom line reported by Ro........

ZIKV replication and the induction of p53: a tale of three places ?

by thelonevirologist in Virology Tidbits

Zika Virus (ZIKV) is a mosquitoe-borne Flavivirus (MBFV), related to other Flavivirus’ that are transmitted by mosquitoes such as Dengue Virus (DENV), Yellow Fever Virus (YFV) or Tick Borne Encephalitis Virus (TBEV) and as such the viral genome is released into the cytoplasm following viral entry and translated into a single polyprotein that is cleaved by both viral and cellular proteases into the 3 structural and 7 non-structural proteins.
Here the induction of p53 dependent apoptosis an........ Read more »

Urinary metabolomics in autism turns up tryptophan (again)

by Paul Whiteley in Questioning Answers

"The tryptophan metabolic pathway collectively displays the largest perturbations in ASD [autism spectrum disorder]."So said the findings reported by Federica Gevi and colleagues [1] (open-access) who provide yet more 'metabolomic' data when it comes to autism to add to the already quite voluminous peer-reviewed matter on this topic (see here for example).Just in case you aren't analytical chemistry-saavy, metabolomics is basically the study of the various chemical fingerprints that th........

'My child is not talking'. Online concerns and internet-based screening for autism?

by Paul Whiteley in Questioning Answers

"Online communities are used as platforms by parents to verify developmental and health concerns related to their child."That was the starting point for the study results reported by Ben-Sasson & Yom-Tov [1] (open-access available here) who approached an increasingly important issue related to how the Internet and social media in particular, is fast becoming one of the 'go-to' options when it comes to parental concerns about their child's development and the question: could it be autism........

Bacteria Help Pitcher Plants Trap Prey

by Elizabeth Preston in Inkfish



Pity the insect that tumbles into a pitcher plant's trap. The slippery walls and waiting pool of water ensure it won't clamber back out. There's nothing left to do but wait to be digested.

The California pitcher plant (Darlingtonia californica) is also called the cobra lily for its curled-over shape that hides its exit from its victims. Unlike other pitcher plants, it doesn't fill its trap from above with rainwater but from below, drawing water up with its roots. But like others, it seems... Read more »

Simple Jury Persuasion: Why you don’t want your  trial videos to elicit awe from jurors 

by Doug Keene in The Jury Room

While you don’t want jurors to think your visual evidence was made by poorly trained technicians—here’s a study that tells us something counter-intuitive that you may find useful (we have). It may not make obvious sense, but you also don’t want jurors to be blown away (i.e., awed, in wonder, overwhelmed by the majesty of […]

Maternal immune activation (MIA) and Old World monkeys

by Paul Whiteley in Questioning Answers

Old World monkeys detailed in the title of this post, specifically refers to a type of animal called a rhesus macaque who were the 'participants' of choice as detailed in a recent study by Destanie Rose and colleagues [1] looking at a concept called maternal immune activation (MIA).Those who followed this blog down the years will no doubt have seen me discuss MIA before in the context of autism and/or schizophrenia (see here for example). The basic theory is that whilst in-utero a........ Read more »
