The US National Science Foundation (NSF) and the Agency for International Development have opened a funding stream for scientists in the developing world. The Partnerships for Enhanced Engagement in Research (PEER) will enable collaborations with scientists who are funded by the NSF; the US National Academies will help to administer the initiative. Applicants need a letter of support from their US-based partners. The first request for proposals will be released in August, and the first round of funding will be awarded later this year. Six PEER pilot projects — focused on areas such as hydrology, biodiversity and seismology — are already being financed in Tanzania, Bangladesh and elsewhere.
