These are challenging times - But I would like to take a moment and say a big THANK YOU to my amazing support group of friends and colleagues, who are always there via email, Zoom, phone calls, in person meetings - and are no doubt the best part of being an academic scientist.

Friday we lost a brilliant mind, colleague, and friend to her battle with pancreatic cancer. Those who knew her will remember Helene Andrews-Polymenis for her warmth, generosity and leadership. She will be missed by many. RIP

Finally, someone has solved a real problem with AI! No more having to take a paper in the format for a journal that rejected you, and reformat it for a new journal. Well done!! formatmypaper.com

Commensal yeast promotes Salmonella Typhimurium virulence - Nature Commensal Candida albicans enhances the virulence and dissemination of Salmonella enterica subsp. enterica serovar Typhimurium.

Excited to share our new publication, out today in Nature! www.nature.com/articles/s41.... @kanchanj.bsky.social led this fascinating fungal-bacterial interaction project. We are grateful for our wonderful collaborators Brian Peters and David Underhill.

We have decided to ban the use of GenAI for research, writing & creative work at our organization.

In fact, we make people sign an agreement saying that their research, analysis, writing, and creative work are *theirs* and not done by GenAI.

Here's the link to the companion paper: journals.asm.org/doi/10.1128/... - together, our studies show that PgtE enables Salmonella to evade innate immunity and cause bacteremia.

Science has more than doubled our life expectancy, revolutionized our quality of life, and powered unprecedented technological advancement. But can we afford to take scientific progress for granted? What happens when science funding is slashed, diversity is suppressed, and pseudoscience takes hold?

Today, the ERC formally adopted a decision to increase its support for researchers moving to Europe.

On top of its normal grants, the ERC offers 'start-up' funding to help PIs establish laboratories / research teams in Europe.

This extra funding is now x2 (up to €2 million!)
