velociraptor = ———————-
Nah man guys you gotta multiply by the directoraptor and divide by the norm of the directoraptor if you want the velociraptor. This is just the speedraptor. It’s like you don’t even know what a velociraptor is..

Human Head Transplants Are ‘No Longer Science Fiction’
Doctors may be able to cure current diseases such as cancer by performing human head transplants, an Italian neuroscientist has claimed.
Dr Sergio Canavero, a member of the Turin Advanced Neuromodulation Group, believes not only that this procedure will be possible in the future but that it can be performed with the technology currently on offer.
"This is no longer science fiction. This could be done today — now," he said, according to The Telegraph. “If this operation is done it will provide a few people with a substantial amount of extra life. The only reason I have not gone further is funding.”
According to the Newsy video report above, Dr Canavero has offered a step-by-step guide to performing the human head transplant - including inducing hypothermia on both donor and recipient, and reconnecting to the new body within the hour.
Dr Canavero’s has based his claims on a head transplant procedure carried out on rhesus monkeys in 1970 by Dr Robert White, but the animals did not stay alive for long as the doctors were unable to reconnect their spinal cords.
“The greatest technical hurdle to such endeavour is of course the reconnection of the donor’s and recipient’s spinal cords,” Dr Canavero acknowledges in the study, according to The Telegraph. ”It is my contention that the technology only now exists for such linkage. It is argued that several up to now hopeless medical conditions might benefit from such procedure.”
Still, his claims have been widely criticised. Not least by Dr Jerry Silver who worked with Dr White on the 1970 transplant.
"I remember that the head would wake up, the facial expressions looked like terrible pain and confusion and anxiety in the animal. The head will stay alive, but not very long," Dr Silver told CBSNews.com. ”It was just awful. I don’t think it should ever be done again.”
He added that the procedure is “light years” away from where it needs to be.
MUST WATCH THE VIDEO!
I don’t usually reblog anything but yeah, everyone should watch this. I also highly suggest reading the paper. Science, folks.

What proto-stars really are.
Above: A plot of redshifted self-absorption of an optically thick molecule, HCO+ (blue), with respect to an optically thin molecule, N2D+ (green), which indicates gravitational collapse of a molecular core onto an accretion disc/ circumstellar envelope within the Perseus molecular cloud. Data taken from the JCMT.

My summer project consists of a molecular emission line survey of ~100 infall candidates within the Perseus molecular cloud using the JCMT. I’ve decided to go into work both Saturday and Sunday in order to finally get these plots before my supervisor gets back from vacation tomorrow (the above are just a small sample of plots). I was really happy to see so many targets with redshifted self-absorption (indicative of gravitational collapse of surrounding gas onto an accretion disc and/or circumstellar envelope), and really surprised to witness blueshifted self-absorption (perhaps indicative of rotation or molecular outflow, for example) in several targets. Finally I can start looking at the data. I am quite happy.

This doesn’t make any sense can someone please link me to the source of this picture because the moon should not be lit when the sun is behind it… that’s literally what an eclipse is
This is precisely why everyone should be sourcing things correctly. It’s not that difficult. It drives me mad to click on a source and be taken back to someone’s personal blog.
Hahaha. In all seriousness though, I don’t understand what about my blog has poor navigation… You shouldn’t have to type in /page/2 or /ask because there are links at the bottom of my page to navigate through the pages and there is a link to the right of my blog to go to the ask page. What’s so difficult?
