In the spirit of Halloween we bring you the science fact and fiction behind the undead. Zombies, those brain loving little guys, (and girls) are everywhere. Sure, we are all familiar with the classic zombie, but did you know that we aren't the only zombie lovers out there? It turns out that nature has its own special types of zombies, but this isn't a science fiction movie, this is science fact! Sometimes fact can be scarier than fiction, so let's dive in.

Appreciating that the autism spectrum is truly a wide and heterogeneous one (or even several?), I'd like to direct your attention today to the findings reported by Jocelyn Bessette Gorlin and colleagues  on the topic of "the experiences of families living with a child with severe autism."In particular, I'd like to highlight the six areas that emerged from the "29 interviews with 22 participants from 11 families" related to family experiences and how, minus any sweeping generalisations, m........

Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder that shares clinical similarities with BHD. TSC results from germline mutations in the Tsc1 or Tsc2 gene, affecting multiple organs, including the kidney and lung. In the kidney, lesions such as multiple renal cysts and renal cell carcinoma can occur. In the lung, patients can develop multifocal micronodular pneumocyte hyperplasia and LAM. TSC proteins are negative regulators of the mTORC1 pathway. The mechanisms of organ........ Read more »

So: "Results indicate that individuals diagnosed with PDD [pervasive developmental disorder] by DSM-IV-TR criteria may not be diagnosed using DSM-5 criteria."That was the conclusion reached by Ferhat Yaylaci & Suha Miral  following their study of 150 children (3-15 years old) diagnosed with PDD "by DSM-IV-TR" whose symptoms/presentation were "reviewed through psychiatric assessment based on DSM-IV-TR and DSM-5 criteria."

Italy's school for water rescue dogs, the Scuola Italiana Cani Salvataggio, has trained hundreds of animals in canine heroics. The dogs work on Italian police and coast guard boats, and with fire departments and the navy. They can even jump into the ocean from a hovering helicopter to save a person.
They're pros at taking commands from humans. So researchers wondered if the dogs could help them understand what kind of command works best: Words? Or gestures?

I just came across a remarkable new paper on the science of salt-passing behavior: Expected Results Show that a Longer Nose Means Slower Times for Passing the Salt and Pepper: A Second Report

Here's how Patrick et al. describe their work:

I'd like to think that the review article by Annik Simons and colleagues  (open-access) highlights some pretty strong evidence to suggest there being at least some connection between some autism and some of the collected inborn errors of metabolism. Indeed, when people generally talk about 'not knowing what causes autism' if we perhaps consider a more plural view of 'the autisms', there is a case to be made to say we might know what causes 'some' autism and some of it might lie in this area..........

Most dogs show signs of impaired welfare at the vet, according to their owners.A survey of 906 dog guardians in Italy found most people report their dog as being stressed at all stages of the visit to a vet clinic, from being in the waiting room to being examined by the vet. 6.4% of dogs had actually bitten their guardian at the vet and 11.2% had growled or snapped at the vet.The report by Chiara Mariti (University of Pisa) et al draws important conclusions about what owners and vets need to do ........

While it may be 2016, there are still some judges who view women and men differently even when they commit the same offense. When it comes to killing your spouse—apparently, the difference lies in the gender of the defendant. Australian researchers looked at the sentencing remarks from nine different judges from trials involving men killing […]
