When Mom and Dad Have Different Migratory Routes, Kids Fly Right Down the Middle

by Elizabeth Preston in Inkfish

It sounds like the setup to a bad joke told by zoologists: What do you get when you cross a bird that always flies to the west with one that always flies east? But the punch line is weirder than you’d guess. Birds’ migratory routes are partly coded into their DNA. A baby that inherits […]The post When Mom and Dad Have Different Migratory Routes, Kids Fly Right Down the Middle appeared first on Inkfish.... Read more »

Japanese Encephalitis Virus, Coronavirus, Autophagy, and the ER stress response

by thelonevirologist in Virology Tidbits

The accumulation of misfolded proteins in the ER lumen induces a stress response commonly known as the Unfolded Protein Response (UPR) or ER stress response, an adaptive signalling pathway increasing the expression of ER chaperones, inhibiting mRNA translation, and stimulating ER associated degradation (ERAD) of accumulated proteins. The degradation via the ERAD pathway in particular requires the formation of double membrane vesicles -more commonly referred to as autophagosomes - which subsequen........ Read more »

Ketogenic diet and the valproate mouse model of autism

Plastic bags responsible for outrageous lack of cute pink piglets

Prenatal and neonatal blood mercury levels and autism

by Paul Whiteley in Questioning Answers

Acknowledging that some topics have the ability to furrow brows when it comes to autism research, mercury and autism is becoming something of a frequent talking point on this blog as a function of a whole slew of articles appearing in the peer-reviewed domain. If I were to [very tentatively] summarise the collected literature so far, it would be to say something like:Mosaic of mercury @ Wikipedia (i) there is quite a bit more research to be done on some sources of mercury being 'l........

Small Things, Big Problem: Microplastics Uptake in Shore Crabs

by Melissa Chernick in Science Storiented

Lately I've been gearing up for some nano-particle research, and so I've been doing a lot of reading about very small things. While perusing the literature, I came across a paper published online in Environmental Science and Technology that takes a look at microplastics.Let’s start with the Great Pacific Garbage Patch, a very good example of this type of marine pollution. This huge collection of marine debris in the North Pacific Ocean is created by an ocean gyre, a stable circular ocean curre........ Read more »

Some Bees Are Busier Than Others

by Elizabeth Preston in Inkfish

It may be time to leave “busy as a bee” with other dubious animal similes like “happy as a clam” and “drunk as a skunk.” That’s because some bees, it turns out, aren’t all that busy. A small group of hive members do the bulk of the foraging, while their sisters relax at home. But […]The post Some Bees Are Busier Than Others appeared first on Inkfish.... Read more »

Know your brain: Meninges

by neurosci in Neuroscientifically Challenged

Where are they?











Close-up view of the meninges surrounding the brain.






The term meninges comes from the Greek for "membrane" and refers to the three membranes that surround the brain and spinal cord. The membrane layers (discussed in detail below) from the outside in are the: dura mater, arachnoid mater, and pia mater. Their positioning around the brain can be seen in the image to the right.What are they and what do they do?The brain is s........ Read more »
