A 🧵 against "violence, whether driven by antisemitism, racism, Islamophobia, or any other form of bigotry..."
We grieve the loss of life in Sydney, Australia, where gunmen attacked a celebration of the first night of Hanukkah, killing at least 11 people. This was a terrifying incident of hate-fueled violence that no community should face.

Scientists issue urgent warning about chemicals, found to cause cancer and infertility as well as harming environment
Scientists have issued an urgent warning that some of the synthetic chemicals that help underpin the current food system are driving increased rates of cancer, neurodevelopmental conditions and infertility, while degrading the foundations of global agriculture.
The health burden from phthalates, bisphenols, pesticides and Pfas “forever chemicals” amounts to up to $2.2tn a year – roughly as much as the profits of the world’s 100 largest publicly listed companies, according to the report published on Wednesday. Continue reading...

Fewer than 60,000 people – 0.001% of the world’s population – control three times as much wealth as the entire bottom half of humanity, according to a report that argues global inequality has reached such extremes that urgent action has become essential.
The authoritative World Inequality Report 2026, based on data compiled by 200 researchers, also found that the top 10% of income-earners earn more than the other 90% combined, while the poorest half captures less than 10% of total global earnings. Continue reading...
