When will quantum computing become more widely available and what technological challenges do we need to overcome in order to achieve this?
Also, would government by scientists result in a utopian society or an absolute shit-fest? My opinion on this often varies considerably and would be keen to hear what other Veeky Forumsentists think

How do you sleep at night knowing that you're contributing so heavily to wrecking our atmosphere?

Some laymen view science dogmatically. It is my opinion that technocratic government-by-scientists would be in practice indistinguishable from theocracy. Ya know, except for the space ships and shit. Unless we go hard commie with it, it will be co-opted by corporate interests. Ya know, just like real life.

What do you use for lysis therapy and how effective is it? Also is anyone developing some alternative to vasopressin/epi that actually helps in a cardiac arrest?
Also give me tips on memorizing anatomy, senpai.

Well... we really can't live without oil and gas. We don't only use hydrocarbons for energy, but also to make an enormous amount of materials including plastics and many pharmaceuticals.
I wish we would change to more sustainable sources of energy, but nothing really comes anywhere near the efficiency of hydrocarbons. The only alternatives that I think have a shot are nuclear fusion and space-based solar. Everything else is waaaay too low-yield. In fact, those other alternative energy sources like wind and biofuels are prohibiting real progress by hogging up all the research money from the alternatives that actually have potential. And this doesn't even consider the transportation problem (i.e. you can ship oil around).
I started working in this industry thinking I would be entering a dying industry. Now I just hope that that is true, but it really doesn't seem like we are moving in that direction. Energy consumption is growing and so is the global population. It is all unsustainable.
I think that a more realistic solution to the global warming problem is to develop the technology to allow us to still use enormous amounts of energy (from wherever) and actively clean up the atmosphere. Some of these efforts are currently underway including carbon capture and sequestration as well as this recent development from Oak Ridge:

I think the oil and gas industry should not be told to stop producing oil (that will never happen as long as people need it), but they should be pressured to develop these technologies to clean things up.
But at the same time, you have to understand that we are not in this position because of the oil and gas industry alone. We have a polluted planet because we use things that don't grow on trees. Anything that you are using, if it's not biological, it had to be mined (or drilled). And somewhere, there is a big pipe of crap going into some river in order to get you those cool new headphones.

I suspect that scientists will sacrifice things like welfare in pursuit of investment in research. Which is like a long-term investment in higher standards of living for all but would almost certainly result in revolt by the impoverished lower classes
We use alteplase for thrombolysis
In myocardial infarction, thrombolysis is reserved for patients with ST-elevation myocardial infarction (STEMI) who are too unstable to transfer for angiogram or who will not reach the cath lab within 2 hrs. It is less effective and less safe when compared to angioplasty. Following thrombolysis, the patient will need an angiogram after 24-48 hrs (so-called rescue PCI). This is because of longer-term issues with myocardial dysfunction and ongoing coronary atherosclerosis leaving a residual risk of re-infarction and cardiac failure. This is a nice reference upon which much of our practice is based:
Di Mario C, Dudek D, Piscione F e al. Immediate angioplasty versus standard therapy with rescue angioplasty after thrombolysis in the Combined Abciximab REteplase Stent Study in Acute Myocardial Infarction (CARESS-in-AMI):an open, prospective, randomised, multicentre trial. Lancet 2008;371:559-68
There is no benefit of alteplase in non-ST elevation myocardial infarction (NSTEMI).
In ischaemic stroke, thrombolysis is less effective than endovascular thrombectomy but has demonstrated a substantial benefit in terms of degree of disability, duration of stay and mortality when compared to standard anti-platelet therapy. The risk is haemorrhagic transformation of the infarct (bleeding into the dead brain). For this reason, it should generally not be offerred beyond 4.5hrs following the onset of symptoms.
For pulmonary embolism, it is reserved for massive PEs causing haemodynamic compromise or arrest. It is difficult to assess efficacy of thrombolysis for PE because the mortality is so high. Lysis does not improve outcomes in PEs without haemodynamic compromise.

Memorising anatomy without context is difficult. I studied anatomy by dissection, which helped. I also read the operative anatomy at the same time which gave me some context.
Many of the names of various structures can give you a clue to the function. There are lots of helpful acronyms as well. Test yourself frequently with flashcards. Always have some in your pocket and when you are waiting for stuff/on a bus/whatever, just get them out and have a read.
