Mark McClusky says for elite athletes today, pushing boundaries and breaking records is all about "the aggregation of marginal gains."
For decades, the United States has been the most generous provider of foreign aid in the world, donating billions of dollars for schools, health clinics and vaccine programs in poor countries.
It’s not common for foreign countries to send their aid money here. But that’s just what happened in the town of Joplin, Mo., which was hit by a mile-wide tornado in 2011.
The tornado killed 161 people and left much of the town in ruins, including the high school and the main hospital in town.
The United Arab Emirates has bought a new laptop for every high school student in Joplin. The town is also going to open a new neonatal intensive care unit with money from the UAE.
