# Urinary metabolomics in autism turns up tryptophan (again)

"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........

# Acceleration of electrons in the solar wind by Langmuir waves produced by a decay cascade by Catherine Krafft and Alexander Volokitin

It was recently reported that a significant part of the Langmuir waveforms observed by the STEREO satellite (Graham and Cairns, 2013) during type III solar radio bursts are likely consistent with the occurrence of electrostatic decay instabilities, when a Langmuir wave $$\mathcal{L}$$ resonantly interacts with another Langmuir wave $$\mathcal{L}^{\prime}$$ and [...]...

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

"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

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

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

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 »

# "Are we expecting too much from the extreme male brain theory of autism?"

The title of this post reflects the commentary published by Andrew Whitehouse [1] (open-access) discussing the meaning of the findings reported by Kung and colleagues [2] who quite categorically stated that there was: "No relationship between prenatal androgen exposure and autistic traits" in their study.OK, androgen exposure and psychology basically refers to the extreme male brain theory and autism which suggests that the so-called over-representation of autism in males is potentiall........

# The Most Interesting Stellar System Of All?

Researchers at the Carnegie Institution of Washington re-examined the Kepler data and determined that it had also been steadily dimming over the course of those four years, on top of its sporadic dips in brightness. For 1,000 days, the rate of dimming observed was constant; then, for 200 days after, its dimming rate suddenly increased by some order of magnitude; finally, for the remaining 200 days, its brightness had remained largely unchanged....

# Do We All Have Split Brains?

When you're doing two things at once - like listening to the radio while driving - your brain organizes itself into two, functionally independent networks, almost as if you temporarily have two brains. That's according to a fascinating new study from University of Wisconsin-Madison neuroscientists Shuntaro Sasai and colleagues. It's called Functional split brain in a driving/listening paradigm

In referring to 'split brains' in their title, Sasai et al. are linking their work to the litera... Read more »

# The Reconstruction of Ships: Sailing the Seas of International Collaboration

Working for both public and private institutions, archaeologists constantly construct and deconstruct narratives about our past, but traditionally publish only a fraction of the sites they excavate and thus destroy. Computers and the internet present a vast range of opportunities for archaeologists to share primary data and foster intercultural online collaborations and reinterpretations of archaeological contexts. ...

# What are Hierarchical Orthologous Groups (HOGs)?

One central concept in the OMA project and other
work we do to infer relationships between genes is that of Hierarchical
Orthologous Groups, or “HOGs” for the initiated.

We’ve written several papers on aspects pertaining to HOGs—how to infer
them,
how to evaluate them, they being
resources, etc.—but there is
still a great deal of confusion as to what HOGs are and why they matter.
