Herman Melville's most enduring contribution to society, long after his novels are forgotten, will be the name of a coffee shop permeating the refuse of the 21st century.

Moby Dick was named for real-life sperm whale Mocha Dick so really it's his legacy, a mocha-hawking logo to outlast the whales.

You don't think of graphic design and aesthetics as an central skill for scientists, and it's not formally taught in PhD programs, but so much of success in science depends on making compelling and intelligible figures.

The same thing could be said for the diseases I study like malaria and schistosomiasis. Yes they’re caused by parasites, but most deaths are really caused by apathy among the wealthy nations and institutions that could muster more effort to prevent them.

Just finished Everything is Tuberculosis by @johngreensbluesky.bsky.social, who eloquently shows that this disease isn’t really caused by bacteria but by social forces: we choose to let people die of a curable illness because they’re mostly poor, nonwhite, and out of view of westerners. Superb book.

Genes in one of the snail genomic regions found in this study

We hope the genes we've found can lead to new strategies for blocking parasite transmission at the snail stage, thereby reducing the >200 million cases of schistosomiasis that happen each year.

In a genome-wide association study of the African snail B. sudanica, we find completely different genes to be important for resisting infection. Although these African snails can be harder to work with, it's important to study them since species aren't all the same.

Life cycle of Schistosoma mansoni from https://blogs.biomedcentral.com/bugbitten/

Schistosomiasis is a human disease from worms spread by snails. I and others have long studied Latin American snails B. glabrata to find genomic regions affecting schisto resistance. But most schisto occurs in Africa, transmitted by other snails. Now with @schistosoma.bsky.social we address this…

Rapid Reviews Infectious Diseases RR\ID is an open-access overlay journal that accelerates peer review of important infectious disease-related research preprints.

Just did a preprint review for RR\ID rrid.mitpress.mit.edu β€”is this the future of peer review? It grew out of COVID-19 need for urgent action from preliminary findings. Sadly parasitic disease lacks this urgencyβ€”not that people aren't dying, but decision makers aren't equipped/motivated to act fast.

With a clamor of bells that set the swallows soaring, July 4th came. The ringing of the boats in harbor sparkled with flags. In the streets between houses with red roofs & painted walls, between old moss-grown gardens & under avenues of trees, past great parks & public buildings, processions moved.
