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

by Paul Whiteley in Questioning Answers

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?

by Jeffrey Daniels in United Academics

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?

by Neuroskeptic in Neuroskeptic_Discover

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

The Reconstruction of Ships: Sailing the Seas of International Collaboration

by Filipe Castro in United Academics

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)?

by Christophe Dessimoz in Open Reading Frame


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

Know your brain: Septum

by neurosci in Neuroscientifically Challenged

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 »

Prescription medication use and autism: good medicines management required

by Paul Whiteley in Questioning Answers

"Prescription drug use and polypharmacy rates among adults with ASD [autism spectrum disorder] are substantially higher than those in an age-, sex-, and race-matched cohort of adults without ASD."That sentence taken from the paper by Rini Vohra and colleagues [1] (open-access available here) is probably not likely to win any 'novel findings of the year' awards given the already quite voluminous data published on the medication use and autism (see here for example).

Diagnosis of congenital malformations during the pregnancy is a difficult theme for families and professionals, and can affects the mental health of pregnant women

by SciELO in SciELO in Perspective | Press Releases

Research considers that the diagnosis of congenital malformation may affect maternal mental health during pregnancy. Symptoms of anxiety and depression can occur from the first quarter, impacting also on the family, especially if the communication of the diagnosis is not careful. They conclude that the coping face to this situation and the impact of bad news can be minimized by the pregnant woman's support network. … Read More →... Read more »

The Hunt for the Higgs Bison Is Over

by Jeffrey Daniels in United Academics

A recently-published study has now resolved the mystery of the bison bones, with the help of some Ice Age cave artists. It turns out that there once existed, during the Ice Age, a hybrid between the now-extinct aurochs (the beast from which we domesticated the cow) and the equally-extinct steppe bison (basically, the Asian version of the American bison)....

MicroRNA expression is regulated by DNA methylation: a complex cascade of gene regulation events

by Barbara Banelli in EpiBeat

MicroRNAs (miRNAs) are non-coding RNAs, roughly 22 nucleotides in size that are central and negative regulators of gene expression. They exert their functions through base-pairing with the 3’UTR of mRNAs and block expression at the transcriptional and post-transcriptional levels, depending on the perfect or imperfect match in sequences between miRNAs and their target genes. miRNAs are central nodes in a variety of biological processes like cell proliferation, apoptosis, migration and dif........

Fun With Non-Ionizing Radiation

by Neuroskeptic in Neuroskeptic_Discover

Does non-ionizing radiation pose a health risk? Everyone knows that ionizing radiation, like gamma rays, can cause cancer by damaging DNA. But the scientific consensus is that there is no such risk from non-ionizing radiation such as radiowaves or Wi-Fi.

Yet according to a remarkable new paper from Magda Havas, the risk is real: it's called When theory and observation collide: Can non-ionizing radiation cause cancer?



There are a few remarkable things about this paper but chief among th... Read more »
