How social media amplifies the worst artificial intelligence boosterism

A spat over claims that GPT-5 solved long-standing Erdős problems exposes how social media rewards exaggerated artificial intelligence breakthroughs while burying more nuanced reality checks.

Researchers model early human pregnancy using organoids and embryos

Scientists have merged human embryos and blastoid models with uterine organoids on microfluidic chips to closely mimic the first moments of pregnancy in the lab, opening a new window into implantation and in vitro fertilization failure. The work could inform future diagnostics, drug screening, and long-term questions about gestation outside the body.
