Scientists have produced the world's most powerful optical microscope, which could help understand the causes of many viruses and diseases.

Do viruses have a cause?

allow us to examine closely viruses and biomedicine for the first time.'"

Biomedicine is an academic discipline. You don't need a microscope to examine it. Here's a jar of physics, go and check if it contains any thermodynamics. Careful with that flask, it's full of chemistry!

Partly because of the cost but also partly because selecting student's

Selecting his/her what?

Researchers say that alumni of the most selective colleges earn, on average, 40 percent more a year than those who graduated from the least selective public universities, as calculated 10 years after they graduated from [huh?-Ed] and found that 'attendance at an elite private college significantly increases the probability of attending graduate school, and more specifically graduate school at a major research university.'

That is NOT a correct sentence. Even if you removed the superfluous preposition it would still, quite frankly, be a shit one.

So what do you do when the food turns out to be poor?

I send it back. One aspect of the service is how well they deal with that. Having said that, I've had 100 instances of poor service for every time the food's been bad. The point is it shouldn't be there as something that I'm expected to negotiate down. The system as it is generally works as long as dickheads like you don't abuse it.

That saves about 50,000 nerd-hours per day.

And nothing of value was gained.

Why not stick a "service charge" on the bill (aside from the obvious benefit of tax evasion)

Because under that system the customer has to pay for service whether it was poor, mediocre, or entirely absent?

"I left Hughes Aircraft Company to work for Moller International..." Illustrates poor grasp of reality, and little innate understanding of practical engineering/ physics.

Or a strong interest in yoghürt.

In Iran, rocks punish half of adulterers.
