The ICE Storm: a year-long escalation Funding, law, rhetoric, violence. How each has fed the other to lead here

The killings in Minneapolis didn’t come out of nowhere.

Funding, legal cover, weakened oversight, and dehumanising rhetoric ramping up over a year. This started on 20 Jan 2025 with Trump's executive orders on immigration.

I lay it out in my latest post.

Letter from Ed Davey to Keir Starmer condemning Elon Musk for inciting violence and urging unity to defend democracy.

I've written to Keir Starmer, Kemi Badenoch and Nigel Farage, urging them to join me in condemning Elon Musk's dangerous remarks inciting violence yesterday.

As leaders, we must stand together and make clear Musk will face serious consequences for these actions.

London HIV charity Positively UK could close over funding crisis Positively UK, which has supported thousands of people with HIV since 1986, is struggling financially.

Support services always seem to become an afterthought when medicine 💊 is available.

But these services save lives, create friendships, educate, build self-love. Something a pill could never do.

We must save them.

Does free schooling give girls a better chance in life? Burundi study shows the poorest benefited most Education policies can be highly effective, but not necessarily for everyone in the same way.

Study finds after Burundi abolished school fees in 2005, girls gained 1.22 more years of education. For very-low income girls, 1 additional year of school reduced teenage motherhood by 7%. Wealthier households likely already ensured education for daughters. theconversation.com/does-free-sc...

The virus possesses a biological characteristic that is not found in nature.
2.

Data shows that all COVID-19 cases stem from a single introduction into humans. This runs contrary to previous pandemics where there were multiple spillover events.
3.

Wuhan is home to China’s foremost SARS research lab, which has a history of conducting gain-of-function research (gene altering and organism supercharging) at inadequate biosafety levels.
4.

Wuhan Institute of Virology (WIV) researchers were sick with COVID-like symptoms in the fall of 2019, months before COVID-19 was discovered at the wet market.
5.

By nearly all measures of science, if there was evidence of a natural origin it would have already surfaced. But it hasn’t.

NIH grant applications often run to well over 100 pages, and if awarded there is a contract to receive funding so researchers can deliver the science in the grant proposal.

It’s not ‘entitlement’ to want that agreement to be honoured.

What does global poverty look like if we rely on the notions of poverty in rich countries like Denmark, the US, or Germany?

And how should this perspective inform our aspirations for the future of global poverty?

If they are criminals, let them face due process and incarceration here or deportation to their country of origin.

A Second Child Dies of Measles in Texas It is the second confirmed measles death in the U.S. in a decade. If the outbreak continues at the current pace, the nation may lose its “elimination” status.

A second child, an 8 yo girl, has died of measles in Texas. Some have asked "could this actually be RFK Jr's or Trump's fault? They've barely been in charge. Vaccination has been falling since before".

It's a valid question, with a clear answer.

Yes. They have ignored the standard of care

No more occupational health research.
No more HIV research. Or tuberculosis. Or sexually transmitted infections.
No environmental health & science research.
No chronic disease research & prevention.

The CRUELTY is the point.
This won’t make anyone healthier.
It will do the exact opposite.

Trump Aid Cuts End Contraception Access for Millions of Women The United States was a key supplier of contraceptives in many developing countries. The Trump administration has ended that support.

The U.S. is ending funding that provided contraception to nearly 50 million women, many in the world’s poorest countries. The change stands to have enormous implications, including more maternal deaths and an overall increase in poverty.

Trump's attacks on universities get ever darker, with the shadows reaching our shores The US has become a hostile and authoritarian state to foreign scientists and is choosing ideology over science.

Colleagues are cancelling their US work trips. I worry that international colleagues in the US are at risk if they collaborate with us on certain topics.
