We don't have a science forum. Humph! So I'll post this here. It is very interesting and I noted that the human-made models were quite good but now the scientists have some more real observational data (actual measurements) they can improve the models and get a better overall picture of what happens.

It was very interesting, Bags, and Mr A will be pleased that his oft-repeated opinion that the seasons are changing because the Earth's orbit is shifting has been given credence! wink

There was an article in The Scotsman yesterday about some new research by scientists at Toronto University and UnivCalifornia Santa Cruz into the role of seawater in climate change.

J. is agog with excitement, and I haven't needed to watch the video because I have been given a blow by blow verbal account of the landing and how it was done. smile I haven't known him be so talkative for quite some time! grin
My interest has certainly been piqued by his enthusiasm and your post B.

As there is no science thread humph and this is and isn't only about health have decided to post here. DH had angioplasty 5 years ago and had 3 stents inserted in his blocked up arteries via his groin (he's fine, he had a heart attack at home and I kept my head and immediately called ambulance although we both got a big fright). At the time I was fascinated enough at the thought of work being done on his heart all the way up there from entry point in his groin. Then I saw something briefly on telly the other night where someone had a coil put in to treat a cerebral aneurysm also with access via their groin! So it's been puzzling me ever since - how do you get to someone's head/brain to work on it, past their heart and all sorts of other organs, up their neck, into their head, having started off at the groin? Is it fairly easy? Is it quick? Is there a clear run in the artery from the groin to the brain or do you have to negotiate obstacles? Think will have to retrain as a surgeon. hmm.

There's some info about angioplasty and vascular stenting here, knotty.

I'm hoping there is a little green man to be seen when the HR pics are available! Seriously though it is fascinating stuff.. i find it mind blowing if i think about it too much!

Thanks, bags - it still doesn't tell me how they get through or past the heart if they're heading for the brain! will ask a doctor colleague smile

Wonderful space photo from Wired Science.

Beautiful.

I wonder if Gransnet took some hints from the Sept. 19th photo? wink
