Sign error sinks three proofs

from HN Digest

A sign error knocks out three OpenAI math manuscripts, and scientists read the genome of a 194-year-old tortoise. The U.S. pauses a green-card step for Microsoft and other firms, a model draws Italo Calvino's cities, and an essay defends elaborate DVD menus.
