Clearly that owl is a reference to the owl who carries written messages in the Harry Potter series.<br />

<hr />
<div>One can test the cytotoxicity (the ability to kill cells) on a petri-dish level for cancer cells and healthy cells separately. However, this is often not done, knowingly neglecting selectivity issues one could face if the tests were done. This should be included in the explanation. The part that is written in the moment mainly explains the title text. [[Special:Contributions/130.60.152.125|130.60.152.125]] 08:34, 27 May 2013 (UTC)<br />

Sorry to correct you. Toxicity is tested for both, healthy cells an cancer cells. But as the targets for drugs are often present in both celltypes, the drug itself affect also both cells. Then you have to choose between certain death by cancer in short time and maybe death or side effects in the long row but survival. It's replacing one evil with another. Only very modern anticancer drugs (e.g. Gleevec) are selective enough to target (mostly) only cancer cells. The drawback is, as cancer in different people is not the same but different cells, you would need different drugs for everybodey affected. One way here lies in the personalized medicine, but that is very expensive...<br />

I've seen plenty of (academic, not industry) studies where tests on healthy cells were not done: The author present the synthesis of fancy new anti-cancer compounds XY, test it on HELA cells, see it is killing them, and publish this - even in high impact journals. This is a fact. [[Special:Contributions/130.60.152.125|130.60.152.125]] 11:09, 27 May 2013 (UTC)<br />

I am pretty sure this comic refers to the most recent overhyped headline of that type 'Vitamin C kills cancer cells'. Since it sounded like a natural remedy it was very widely spread, and widely misunderstood.[[Special:Contributions/62.220.2.194|62.220.2.194]] 11:38, 27 May 2013 (UTC)<br />

Oxygen kills cancer cells! Under high enough temperatures it reacts with organic molecules in cancer cells, and produces CO2, H2O and some other stuff. --[[Special:Contributions/81.23.24.43|81.23.24.43]] 12:28, 27 May 2013 (UTC)<br />

Actually, oxygen is quite toxic to all cells, even though our cells will quickly die without it. A very large proportion of our physiological pathways are involved in the two tasks of (1) using oxygen to meet the energy needs of our cells while (2) protecting our cells from its toxicity. Outside our cells also, oxygen is both essential and dangerous: much of our technology would not work without oxygen from the air, but that same oxygen creates a fire hazard.<br />

That 99.99% number on the hand sanitizer is probably made up anyway. Any actual scientific measure of effectivity would need to take into account different resistance of different types of germs. So, question is, is the sanitizer more or less effective? -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 10:35, 16 January 2013 (UTC)<br />
<br />
:I actually had in the back of my mind that the 99.99% figure wasn't a "dead germ count," but the number of strains of germs the sanitizer has the ability to kill. I.e. there are some strains which it doesn't kill. &mdash;[[Special:Contributions/98.122.166.235|98.122.166.235]] 12:59, 16 January 2013 (UTC)<br />

Shouldn't 200 million times .01% actually be equivalent to 200 million times .0001, which equals 20 000 germs? [[Special:Contributions/134.169.169.121|134.169.169.121]] 13:16, 16 January 2013 (UTC)<br />

Yes, 2 000 000 * .01% = 20 000 is correct<br />

Quite aside from the arithmetic, right now the US has two epidemics: influenza and norovirus, which is often known by the misnomer of "stomach flu." According to infectious disease experts, while alcohol is likely pretty effective against bacteria and SOME viruses including influenza, alcohol is probably NOT very effective against norovirus. The best way to stop the spread of norovirus: frequent hand washing with soap and water.<br />
