The four who are trying to make a difference: Dr. Fred Binka, a doctor who's making it easier to do high-tech science in low-tech environments; Emilio Emini, a biologist who has spent 23 years fighting HIV; David Edwards, a biomedical engineer at Harvard University who thinks patients can ward off disease with a cheap inhalable powder, and Christopher Egerton-Warburton, a banker who has improved the health of poor people by getting rich people to invest in bonds.

-- Tokyo Bureau Chief Christian Caryl writes about new programs all over
the world that are rediscovering and proving the usefulness of
"primitive" water systems such as Chinese foot pumps, buried aqueducts
and other ancient water-supply technologies. While the older systems
may never entirely supplant modern, mechanized solutions, they can
prove more effective and sustainable in many cases, Caryl reports.
-- Senior Editor Steven Levy reports that One Laptop Per Child, the as-
yet-unproven project to deliver millions of cheap computers to kids in
developing countries, is finally rolling out its innovative XO devices
(which are manufactured not at the promised $100 price point but $188).
The problem is getting someone to buy them for the kids who need them,
Levy says. One Laptop Per Child has made a major change to its business
plan. They are accepting $200 online donations to buy a laptop for a
child. Benefactors can also get a computer for themselves with the
"Give 1 Get 1" option allowing them to purchase a laptop for $399, a
price that includes a second one to be delivered to a kid who may use
it to do something great, Levy reports.
