Of all the countries that have pledged money to the UN's $1 billion fund to fight Ebola, only Colombia has paid, the BBC reported, bringing the fund total to $100,000.

There was a flurry of other Ebola news Friday morning: President Barack Obama appointed an "Ebola Czar," a Pentagon parking lot was shut down after a woman who had recently traveled to Africa began vomiting and the State Department announced that a healthcare worker who may have come in contact with the virus is on a cruise ship in Belize. We'll have more later today.

120,000 people

Bioethicist Sigrid Fry-Revere argues that the current law, which contains strict guidelines about how donors can be compensated for expenses related to their donation, is preventing patients from getting the treatment they need.
