Chris Oyeniyi runs a small tech startup in Lagos, Nigeria. It's a smartphone app called KariGO that he says is "like Uber but for trucks." Businesses or factories can use it to hire big semitrucks to move their products around the country. He started it in 2016 and now has 11 office staff members, and he owns a few dozen trucks.

Staple foods and seasonings like flour and salt could be made more nutritious with a new technology that borrows from the pharmaceutical industry, according to a study published Wednesday in the journal Science Translational Medicine.

Last week, Turkey agreed to a cease-fire in its military offensive targeting Kurdish-led forces in northeastern Syria. But even with hostilities largely on hold, the invasion's humanitarian impact continues to unfold.

When Claude Tayou Tagny was a young medical student on a rotation through clinics in rural Cameroon, he treated a woman during a difficult childbirth. She had lost, by his estimate, at least three pints of blood, triple the normal amount for childbirth and equal to roughly 30% of her total blood volume.

Tagny, with no supply of blood on hand, did the only thing he could: put out a call to the woman's family for emergency donations. He was only able to raise one pint.

"It was not enough," he says. The baby survived, but the woman did not.
