Henry Gee

Hello, book people! I am the book content editor for Reactor Mag and I'm looking for 2026 sci-fi, fantasy, horror, romantasy, and speculative books coming out in the second half of the year! If you have an adult or YA SFF/H book out July-Dec (or publicist), share the link/info here!

Deadline for applying is 9 march. Don't miss out!

The hardest part of writing a book is getting a synopsis into a state that's good enough to be shown to publishers. It never gets easier. After several versions and the help of my agent @jillgrinberglit.bsky.social I've managed it for my next book. (Advice to new authors - GET AN AGENT)

Ursula K. Le Guin — Nominate a Book for the Ursula K. Le Guin Prize for Fiction

It's time! Nominations are now open for the 2026 Ursula K. Le Guin Prize for Fiction, which will be given to a work of imaginative fiction, published in 2025, that reflects the concepts and ideas that were central to Ursula’s own work.

How an exercise-activated enzyme helps to keep the brain young Nature - A protein reinforces the blood–brain barrier, which becomes leaky with age.

Exercise prevents brain ageing and memory loss by strengthening the blood–brain barrier

Let’s hope they do it sooner rather than later.

Eventually, but even a small amount of genetic interchange with Earth will delay this. Speciation is promoted by small population size but that also makes extinction more likely. Colonising Mars is a barmy idea IMHO

🚨There is still time to apply! Deadline March 11

Environmental exposure trains the immune system to dampen allergic responses Clean living conditions that lessen exposure to microorganisms are linked to an increase in allergies. Mouse data reveal how the environment affects allergic immune responses.

The most influential explanation of a recent surge in allergies is the hygiene hypothesis

Clonal-aggregative multicellularity tuned by salinity in a choanoflagellate - Nature The choanoflagellate Choanoeca flexa forms motile and contractile cell monolayers purely clonally, purely aggregatively or through a combination of both processes depending on environmental conditions.

A study in Nature shows that the single-celled form of a tiny, aquatic organism can turn into a multicellular version by three different routes. The discovery adds insight to the possible origins of multicellular life, suggesting a previously unrecognized degree of flexibility. 🧪

Human hippocampal neurogenesis in adulthood, ageing and Alzheimer’s disease - Nature Mapping of neurogenesis in human hippocampi across ages and different cognitive abilities using multiomic single-cell sequencing reveals distinct signatures between cognitive preservation and decline.

Aged adults with extraordinary memory capacity – known as SuperAgers – exhibit a unique neurogenesis profile with a surprisingly high number of young neurons, according to a study published in Nature. 🧪 #Neuroscience

No. Keep them and donate them with all your other papers to a University so that one day there’ll be a Philip Ball Archive.

Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).

A brief 🧵 (carried over from the old place)

What I read in January and February occamstypewriter.org/cromercrox/2...

Flexible paths to multicellularity Close relatives of animals can become multicellular if distinct individuals join together or if dividing cells remain attached. A species has been found to use both mechanisms.

Thanks to reviewers who helped us considerably improve and extend the work (which is now very large indeed), and to the editor @endofthepier.bsky.social for shepherding this to publication. S Coelho and
J Lotharukpong wrote a News & Views with a cleverly punny title. www.nature.com/articles/d41...

Look, I don't know if this is true... I just want it to be

I confess, right now the title "Scientific American" reads like an oxymoron. And it's not the publisher's fault.

A silly simple pen drawing of a paper-clip-shaped ammonite with eyes like those of Clippy the office assistant. A speech bubble reads "It looks like you're evolving. Would you like help?"

Yes yes yes

Sea-urchin spines generate electrical signals in flowing water The spines of sea urchins can generate a voltage when water moves around them — a phenomenon that could be used to design underwater flow sensors.

There are still people who think climate change is a scam. Well, as Bobbi Flekman, the Hostess with the Mostest, once said - money talks. Bull$h1t walks.

An ancient mass grave reveals targeted killing of women and children in the Early Iron Age Nature Human Behaviour, Published online: 26 February 2026; doi:10.1038/s41562-025-02400-5On discovering that one of the largest prehistoric mass graves of Europe predominantly held violently killed women and children, we used a battery of methods to investigate how this gender-selective and age-selective pattern reflected the strategic disruption of power networks and lineages in the Early Iron Age.
