Almost yes. Omit the 'since' and we have

every day we find out something new...: The problem is, that because we

*have* these new discoveries, it does

*not* automatically follow that these are then quickly applied in practical ways.

Hence, we

*cannot* write:

New scientific discoveries are being made every day of the week, SO new ideas are quickly applied in practical ways.

'for' in the sentence would be a conjunction, meaning 'therefore' or 'since' :

New scientific discoveries are being made every day of the week, THEREFORE new ideas are quickly applied in practical ways. That is not the meaning of the whole sentence.

New scientific discoveries are being made every day of the week, SINCE new ideas are quickly applied in practical ways. This implies that all research/all inspiration leading to new discoveries occurs simply

*because there is a ***demand** to apply ideas in practical ways.

However, these days 'new ideas

*are* quickly applied in practical ways' - a lot more so than in other ages.

New scientific discoveries are being made every day of the week, BUT unlike in other ages when new ideas could be published, and then just sit in libraries as interesting theoretical knowledge ,

these days new ideas *are* quickly applied in practical ways.
