Contraception, fertility support, safe abortion, menopause services, mental health care, preventative checkups & other essential care are still out of reach for too many women.

Women deserve better.
They need:
- Affordable and safe health services.
- Rights-based options for reproductive health.
- Care that meets her unique needs.

Let’s close the gapβ€”act now.

there's so much bad in the world but there's also people who lift up and carry an elderly bat around every day so he can pretend he's flying again, and that's the part of the world I think is worth fighting for

Lessons From Stepping Out of Survival Mode On regulation, integration and the cost of becoming more yourself

Some generalised lessons from stepping out of survival mode. Embodied insights from my month away.

Iran’s people were facing a horrible shortage of water before the war began. If we are destroying desalination plants and setting fire to Teheran we are committing unfathomable crimes.

Today should be your 38th birthday..
When you lose your son you lose more than a child you lose a piece of your heart and your joy. Life is forever altered, and nothing can ever fill that space. Yet in my soul, he remains, my precious boy, forever loved. His laughter, his smile, and his love are woven into who I am. My love for him will never fade. Yor are my pride and my joy - you've made a change that cannot be broken..

This Is How a Child Dies of Measles When your family becomes a data point in an outbreak

This is a vivid, horribly relevant read. β€œShe does not sleep well. And as you lift up her pajama top to check her rash one morning, you see that her breathing is labored, shadows pooling between her ribs when she sucks in air. You suffer an icy moment of realization: This is a medical crisis.”

This week marks a year since 10% of the CDC work force was fired. We are more vulnerable to the next pandemic,outbreak monitoring is crumbling, measles is basically endemic again,vaccine guidelines are now RFK Jr fan fiction.
All it took was one year.

Rare, dangerous side effects of some COVID-19 vaccines explained β€œGroundbreaking” study uncovers why adenovirus-based shots caused life-threatening blood clots and bleeding in some people

Five years after the rollout of Covid-19 vaccines started, it seems the mystery of why the Astra-Zeneca and J&J vaccines led to a rare but deadly side effect of unusual blood clots and bleeding has finally been solved. 

It's a fascinating case of molecular mimicry that may help make vaccine safer.πŸ§ͺ

1/ ProPublica collected handwritten letters in mid-January from children held at the Dilley Immigration Processing Center, the same facility where 5-year-old Liam Conejo Ramos was taken.

Hundreds of kids are still detained.

Around the world, politicians and businessmen are resigning from their positions because of the Epstein Files.

Except in the United States.

Here: Zero shame, zero consequences.

We need resignations, investigations, impeachments, and punishments now. Should have been years ago.

How I Work What I’ve learned about authority, capability, and the conditions for meaningful change

A lot of the stuff I’ve been writing about recently is about modelling better behaviours and holding myself to account.

This isn’t entirely how I work. It’s how I WANT to work.

Burnout and Disengagement Are Signals Why exhaustion and disengagement are signals, not failures

Burnout and disengagement aren’t individual failures. They’re signals of systems under strain.

When effort replaces capacity and responsibility is pushed down without authority, people adapt. Some burn out. Others disengage.

Until conditions change, transformation only reproduces the same risks.

Spotlighting The World Factbook as We Bid a Fond Farewell - CIA

The Trump admin has shut down the CIA’s World Factbook, a country reference that for six decades has provided data on birth and death rates, major exports, and more. Long used by government officials and by researchers, educators, and journalists, the database was taken offline today.

OPM removes language on back pay for furloughed feds from shutdown guidance | Federal News Network OPM's shutdown guidance also added a section stating that performance-based adverse actions against employees are allowed in some cases during a funding lapse.

1/5
OPM quietly revised its Jan 2026 shutdown guidance. The new text backs away from guaranteed back pay for furloughed feds -- even though a 2019 law already guarantees it. The statute didn’t change; the guidance did. πŸ”

This whole article is just flabbergasting. Here for instance, he's either forgotten about the massive measles epidemic 1989-1991 or is ignoring it. How different do you think our treatment is today? (Not that much!)

I've talked to people on the ground about the strike here tomorrow, and the single thing everyone brings up is just how shockingly wide the support for the strike is. Businesses that no one would have expected to support it are doing so.
