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 »

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 […]

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  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 »

The title of this post reflects the commentary published by Andrew Whitehouse  (open-access) discussing the meaning of the findings reported by Kung and colleagues  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........

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....

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

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. ...

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
how to evaluate them, they being
increasingly adopted by orthology
resources, etc.—but there is
still a great deal of confusion as to what HOGs are and why they matter.

Where is the septum?
The term septum, when used in reference to the brain (it is a common anatomical term used to refer to a partition), indicates a subcortical structure in the forebrain that is found near the midline of the brain. The septum in humans can be separated into two structures: the septum pellucidum and septum verum. Each of these is sometimes........ Read more »

Research considers that the diagnosis of congenital malformation may affect maternal mental health during pregnancy.
