Today is #WorldCancerDay

~1 in 5 people will develop #cancer in their lifetime

Each diagnosis affects not just one person, but families, communities, and futures

Grateful today for patients, clinicians, researchers & advocates - and to appreciate that progress depends on acting together

#WCD2026

Thanks Santi, very much appreciated!!

Huge congratulations to Fran on being awarded the ERC Consolidator Grant! 🎉

Such a well-deserved recognition of an outstanding trajectory and a truly creative, exciting proposal on T-cell clonal hematopoiesis.

Can’t wait to see the discoveries that come out of this project.

So proud of you! 👏✨

👏 ¡Enhorabuena Francisco Martínez Jiménez‼️

Epigenetically driven and early immune evasion in colorectal cancer evolution - Nature Genetics This study nominates immune escape as an early event in colorectal cancer and shows how this can be driven through both genetic and epigenetic changes.

New @natgenet.nature.com paper from the brilliant @eszterlakatos.bsky.social presents evidence that chromatin alterations disrupt antigen presentation & neoantigens in colorectal cancer. Also that immune escape is part of the "Big Bang", at the outset of CRC growth. www.nature.com/articles/s41...

Fantastic #Blutorial by our friends and colleagues at the @batllelab.bsky.social . We are so happy to collaborate with them.

@meritxellnov.bsky.social and Mireia Novell in the lab have participated in this very important piece on metastatic colorectal cancer. 👏🏼👇🏼👇🏼👇🏼

As genomic profiling expands, such approaches are vital to balance patient benefit, cost, and sustainability. But will require systematic data generation and sharing to achieve real-world impact. End.

4/
We also model the statistical power needed for clinical implementation of such biomarkers, offering a roadmap for translating non-response biomarkers into clinical practice. Our analysis revealed that we are still underpowered to implement it with existing data

3/
Under stringent analytical control, we found several known and novel biomarkers, many aligned with resistance mechanisms (e.g., KRASG12X in colorectal cancer treated with comb. chemotherapy agents, immune escape events in melanoma patients treated with ICIs). See full list in Supp. Tables

2/
We analyzed data from >2,500 patients with WGS/WTS and matched clinical outcomes — the largest dataset of its kind — to systematically identify non-response biomarkers.

1/
🚀 Excited to share our preprint tackling a key gap in precision oncology: the lack of robust non-response biomarkers to guide clinical decisions.
These markers can spare patients from ineffective treatments and ease pressure on healthcare systems.

End GDP mania: how the world should really measure prosperity The obsession with economic output as a measure of human development puts sustainability on the back burner. Researchers can now help to devise better indicators.

Time to end the GDP mania

Doughnut of social and planetary boundaries monitors a world out of balance - Nature A revised ‘Doughnut’ providing a visual assessment of trends in social deprivation and planetary degradation over the past two decades shows more than doubling of global GDP accompanied by accelerating ecological overshoot but only a modest reduction in human deprivation.

The richest 20% of nations, with 15% of the global population, contribute more than 40% of annual ecological overshoot; the poorest 40% of countries, with 42% of the global population, experience more than 60% of social shortfall 🧪

‘Half the tree of life’: ecologists’ horror as nature reserves are emptied of insects A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides

Experts are concerned, as a number of scientists 🧪have recorded huge die-offs of insects in nature reserves around the world. The reported collapse of insect populations in supposedly protected regions is part of a newer phenomenon. 🌏🐜

Powerful stuff from @juliosaezrod.bsky.social who found himself on the other end of the process - as a patient not a computational biology researcher - giving him insight into both research and patient perspectives. Huge credit to Julio for talking about his experiences here
