New preprint! Really excited to share our spatial proteomic study on Plasmodium falciparum schizonts . We used hyperLOPIT to map thousands of proteins—from apical invasion organelles to the infected red blood cell surface.

A huge thank you to all my co-authors for this great collaboration!

The forgotten half of scientific thinking | PNAS The forgotten half of scientific thinking

“The idea that taking walks, reading things unrelated to your research, and hanging out with strangers in a campus pub should be considered part of the serious process of thinking, but might well meet with skepticism in practice.”

Many congratulations Ryuji. Your first paper on Plasmodium biology. Well done.

Happy Holi from our lab. Festival of colours. This to welcome the spring which I hope is round the corner.

Why? Because respect isn’t about clothes—it’s about character. And that’s something money can’t buy.

Modes and mechanisms for the inheritance of mitochondria and plastids in pathogenic protists Pathogenic protists are responsible for many diseases that significantly impact human and animal health across the globe. Almost all protists possess mitochondria or mitochondrion-related organelles, ...

Plastids & mitochondria arose from separate endosymbioses of prokaryotes.Their prokaryotic ancestry makes them susceptible to antibiotics. Antibiotics kill pathogenic protists by targeting their plastids or mitochondria. Here we review the lop sided inheritance.

I like this plan from EupathDB - No paywall 😀. We can volunteer to pay a fee from lab budgets. And a "mortgage calculator" tool coming up in Jan to guide us estimate that fair price based on several variables like lab size and usage.
