sci-fact:

“ I can live with doubt, and uncertainty, and not knowing. I think it’s much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers, and possible beliefs, and different degrees of certainty about different things, but I’m not absolutely sure of anything, and then many things I don’t know anything about, such as whether it means anything to ask why we’re here, and what the question might mean. I might think about it a little, but if I can’t figure it out, then I go on to something else. But I don’t have to know an answer. I don’t feel frightened by not knowing things, by being lost in a mysterious universe without having any purpose, which is the way it really is, as far as I can tell, possibly. It doesn’t frighten me. ”

Transtentorial herniation, Uncal herniation

occurs when the medial aspect of the temporal lobe compresses the free margin of the tentorium.

1. Compress CN III → ipsilateral pupillary dilation
※Note the parasynpathetic nerve of CNIII is first affected by compression, followed by motor nerve damage. 

 

2. Compress ipsilateral Posterior cerebral artery → hypoperfusion of the primary visual cortex, contralateral hemianopsia

 

3. Compress ipsilateral crus cerebri → contralateral hemiparesis

sometimes contralateral crus cerebri is compressed, causing paresis which is ipsilateral to the mass lesion(Kernohan’s notch)

 

4. Duret hemorrhages = Hemorrhagic lesions in the midbrain and pons

Today, for the first time in human history, global CO2 levels have risen above 400 parts per million.

We can look at this day as a sad reminder of what we are doing to our planet - or we can look at it as the last push we need to enable the renewable energy revolution we need worldwide.

The Energy Revolution is not only possible - it’s already underway @ Greenpeace

Can we take a moment and contemplate our inability and incompetence to stand up for our planet? To recognize the fact that we are not doing a damn thing about this?!

The Human Brain in cross section (near the midline)

The following structures can be located here:

Cerebellum, 4th ventricle, Superior colliculus, Inferior colliculus, Periaqueductal gray, Pons, Dorsal funiculus, MLF, Medial lemniscus, Red nucleus, Mammillary body, Pineal body, Posterior commissure, Anterior commissure, Thalamus, and Fornix.

Part of me misses anatomy. Just a small tiny bit of me.

Bioengineered kidney makes urine after transplantation

Here’s research that could take the piss out of disease—and it’s no joke. For the first time, scientists reporting in Nature Medicine have created lab-grown kidneys in rats that produce urine after transplantation.

If the work can be replicated in humans, patients suffering from end-stage kidney disease could one day have “an organ that’s grown on demand—a tailored organ that can be transplanted and replaces the failing organ,” says study author Harald Ott, a bioengineer at the Massachusetts General Hospital in Boston.

Happy 87th Birthday to Sir David Attenborough - the face (and voice) of natural history television for over 60 years. He is the only person to have won a BAFTA for black and white, colour, HD and 3D tv.

Watch: Attenborough | 60 Years In The Wild

I love this guy! If only he can reads my lecture notes that would make studying much more interesting
