this disease resulted in what are described as “ground glass

The pharmaceutical industry often comes under fire, especially
during times of a pandemic, like the COVID-19 outbreak we are
seeing right now. This is because the sector has become a sort of
poster child for the patent system – a firm invests a large amount

lives, but in return it gets to be the monopoly seller of this drug
for 20 years. To put some specific figures on it,...

change to think through can be
daunting. The greatest immediate impact of the COVID-19...

As part of the anti-recession stimulus bill, the federal
government allocated $19 billion dollars to subsidize the
modernization of medical records. You’ve been considering making
the switch to computer-based records for some time now, and the
stimulus funds will certainly make that decision a little easier
now. But, which system will you buy? You’ve visited a number of
other practices and hospitals to see what they’re using, and you’ve
found a dizzying variety—desktops, laptops, PDAs, smartphones, all
running different software....
