I'm super excited to share that I co-hosted a BBC Earth documentary called Cosmic Vistas, which airs on Friday night! I don't appear in every episode, and I'm one of a group of scientists recruited for the show. But still, this was a super fun dream come true! bbcearth.ca/shows/cosmic...

Medical parasitology question: Multiple parasites cause diarrhea (e.g., species of cryptosporidium, cyclospora, giardia, entamoeba), but as far as I can tell - only Giardia intestinalis is described as producing greasy and foul-smelling diarrhea. What is giardia doing differently?

Daniel and Kelly chat with Dr. Chelsea Wood about rat lungworm - a particularly unpleasant nematode parasite that is spreading way outside of its native range. www.iheart.com/podcast/105-... Chelsea's book, Netherworld, is available for pre-order now: www.hachettebookgroup.com/titles/chels...

That's one of the many topics explored by @zachweinersmith.bsky.social and @weinersmith.bsky.social in their excellent book "A City on Mars" 💙

On Tuesday at 1PM eastern I'm going to be on a panel w/some truly amazing experts & executives to talk about whether we're ready to settle Mars. This panel arose from the "2025-2026 Beyond Earth Report: On To Mars Readiness Assessment". Sign up to watch here: www.tickettailor.com/events/beyon...

Hello! I‘m listening to the audiobook of A CITY ON MARS and it’s both chock full of reasons that settling anywhere in space is not, in any way, a straightforward or simple thing and very funny. We aren’t living on the Moon or Mars, folks. Not any time soon.

Neat! 500 per 1,000 men during the Boer War were admitted for STIs. The solution? Not shame, but "health education, increased temperance, better leisure facilities within barracks, and improved treatment methods "for both sexes under conditions to which no penal stigma (was) attached.""

Ok, so that's a really truly a viral tweet (quite a way to wake up!) so I will take this opportunity to say buy @weinersmith.bsky.social and @zachweinersmith.bsky.social 's excellent book "A City on Mars" to understand the MANY MANY reasons why *nobody* right now will succeed at living on Mars.

FYI: A total ass-whup of a book by @weinersmith.bsky.social & @zachweinersmith.bsky.social … a dispositive Bezos & Musk slapdown. You will probably break a rib laughing in places. @karaswisher.bsky.social @jlswishmd.bsky.social @neildegrassetyson.com @brianklaas.bsky.social z

Thinking of joining in on the SpaceX IPO? You might want to check the fine print. @weinersmith.bsky.social and I wrote a piece about an important detail disclosed in the company's paperwork and why it's something potential investors should be wary of. www.houstonchronicle.com/opinion/outl...

SpaceX investors beware: Here’s why Elon Musk’s plans for Mars won’t work

SpaceX incentivizes Musk to create a million-person colony on Mars. But in his lifetime, that’s not realistic.

.@scottsolomon.bsky.social & I wrote an Opinion piece for the @houstonchronicle.com abt SpaceX's IPO. It massively incentivizes Musk to get 1 million people on Mars in ~30 years. We won't know if it's safe for 1 million people to be on Mars on that timeline www.houstonchronicle.com/opinion/outl...

For all would-be SpaceX investors, reading "A City on Mars" is a strong recommend. Very funny on the many ways space is terrible, uneconomic, and the decades/centuries of (boring, non-phallic rocket related) research needed to make settlement even a vaguely realistic proposition.
