These patients saw what comes after death. Should we believe them? Researchers have developed a model to explain the science of near-death experiences. Others have challenged it.

Our second most read story right now comes from @markjohnpost.bsky.social, a Pulitzer-winning science reporter on our team, who announced he was laid off.
