What if we tolerated diseases?
The immune cells that fight bacteria and viruses are well-known. But some scientists think we should devote more attention to a second prong of defense: one that allows our bodies to more harmlessly…
«“Bacteria, they like glucose,” says Soares. Therefore, the body often shuts down glucose production when it is infected, and infections often make animals lose their appetites. These twin actions limit the pathogen’s energy source and so help survival of the host.»
Evolution Didn’t Wire Us for Eight Hours of Sleep

The science of a wandering mind
More than just a distraction, mind-wandering (and its cousin, daydreaming) may help us prepare for the future

There are more active volcanoes than you think
OPINION: Volcanologists warn that magma-filled vents evolve over time, leading to an underestimation of the number that might erupt — especially those capable of the biggest explosions
What is Refind?
Every day Refind picks the most relevant links from around the web for you. Picking only a handful of links means focusing on what’s relevant and useful. We favor timeless pieces—links with long shelf-lives, articles that are still relevant one month, one year, or even ten years from now. These lists of the best resources on any topic are the result of years of careful curation.
How does Refind curate?
It’s a mix of human and algorithmic curation, following a number of steps:
- We monitor 10k+ sources and 1k+ thought leaders on hundreds of topics—publications, blogs, news sites, newsletters, Substack, Medium, Twitter, etc.
- In addition, our users save links from around the web using our Save buttons and our extensions.
- Our algorithm processes 100k+ new links every day and uses external signals to find the most relevant ones, focusing on timeless pieces.
- Our community of active users gets the most relevant links every day, tailored to their interests. They provide feedback via implicit and explicit signals: open, read, listen, share, mark as read, read later, «More/less like this», etc.
- Our algorithm uses these internal signals to refine the selection.
- In addition, we have expert curators who manually curate niche topics.
The result: lists of the best and most useful articles on hundreds of topics.
How does Refind detect «timeless» pieces?
We focus on pieces with long shelf-lives—not news. We determine «timelessness» via a number of metrics, for example, the consumption pattern of links over time.
How many sources does Refind monitor?
