Young scientists should be valued by their commitment to education, their dedication to fighting inequality in science, and their efforts to democratize science.

Geri Richmond and Hashemite University molecular biologist Rana Dajani spoke after Richmond's AAAS presidential address to open the 2016 AAAS Annual Meeting. Some of the most intriguing news at the 2016 AAAS Annual Meeting focused on the tiny: a miniscule cosmic ripple born 1.5 billion years ago, and a millimeters-long mosquito responsible for an emerging health crisis. But the science behind these discoveries is huge in scope and in importance, reflecting the ongoing achievement of international research teams addressing complex challenges in science and society. Efforts to track the spread of Zika virus in the Americas, and the landmark discovery of gravitational waves, both demonstrate the power and potential--and the need--for global collaborations between scientists, speakers emphasized at the 11 to 15 February event, held in Washington, DC. In particular, scientists in developing countries must work as equal partners with their counterparts in developed countries to solve border-crossing challenges like climate change and virus outbreaks, said outgoing AAAS President Geri Richmond in her address at the start of the meeting.
