I love visiting India! India has made great progress in reducing poverty and hunger and improving access to healthcare and education. The key to this progress is India’s greatest resource: its people. During my visits, I get to meet with health workers, teachers, scientists, and politicians.

In low-income settings, ultrasound machines simply aren't practical. They're bulky and expensive. It takes special training to operate them. Then the images need to be read by a radiologist or other expert, people who are in short supply in developing countries.

LuxWall and Aeroseal are two innovative companies that are addressing the ways buildings leak energy through windows and ducts. Learn more at https://gatesnot.es/3CWM9E1

If you care about climate change, you should care about transmission. The U.S. can invest trillions of dollars in lowering emissions, and it won’t get us to zero unless we improve the way we get electricity to people. Read more at https://gatesnot.es/3ktQF6D
