September 27 CERVAVAC, India's first homegrown cervical cancer vaccine, is priced at just $2.50 to $5.00 per dose — a fraction of what HPV vaccines have cost in wealthy countries for nearly two decades.

September 26 Same-sex marriage in Cuba is now legal, after roughly two-thirds of voters approved a sweeping new family code that also opens adoption to gay couples. Before the referendum, the draft was workshopped at more than 79,000 neighborhood meetings, drawing over 300,000 citizen suggestions that shaped the final text.

September 20 Equatorial Guinea's abolition of the death penalty shows how far the global movement against state-sanctioned execution has reached — even into governments long considered among the world's most authoritarian. President Obiang, in power for over 43 years, signed the change into a new penal code, meaning future governments would need to reverse legislation, not simply resume executions by decree. Still, the reform exists alongside a documented record of forced disappearances, arbitrary detention, and torture...
