A new way to write and publish research▲39
Over the last two years, we’ve seen just how quickly science can move when it’s conducted out in the open, and the focus is on content rather than the publishing process. We’ve built a new way for researchers and scientists to communicate and share their findings with the world - rethought from first principles, with a lot more coming soon. Free to use, and available now for anyone with a university email address. We’re whitelisting organizations that conduct and publish research on a rolling basis. Please forward feedback and thoughts to [email protected] or comment here!
