This poor beetle was probably just minding his own business before a gigantic flying terror swooped down, stabbed him with its proboscis, and started digesting his insides.
Robber fly with beetle prey.
Jeremy Pickett-Heaps from the University of Melbourne shared this nice video of Volvox carteri development:
I may have to take back some of the things I’ve said about Andrew Weil (“Pseudoscience at the University of Arizona,” “Journey into bullshit with Deepak Chopra and Andrew Weil,” “Andrew Weil advocates cupping“). Not that any of it isn’t true; he really does season his mostly sound health advice with some pseudoscientific bullshit. But damn, Dr. Weil is a paragon of rationality compared to these two:
Great article on homeopathy for traumatic brain injuries. Homeopathy can offer a lot for both the acute and… https://t.co/SQ3j5QM1L4

The article the tweet links to is by Larry Malerba, DO, DHt, “Physician, educator, author, and pioneer of new paradigm medical thinking.” I don’t know what a DHt is: distributed hash table? Dihydrotestosterone? If anyone knows, please share in the comments.
I host a semi-regular game night, and last night we tried out the game Evolution. I’ve been meaning to try it for a while, even ordered a used copy from an Amazon seller who turned out to be a scammer.
I see that it’s been nearly three weeks since I posted, maybe the longest gap since I started this. It wasn’t a conscious decision, just a combination of deadlines and life in general.
Back in April, I got an email out of the blue from a ‘Project Manager’ at Research Features, a digital magazine “…born from a passion to break down barriers that exist in the dissemination life cycle from researcher to the mass audience.”
Dear Dr. Herron
I would like to speak with you concerning your work with the Collaborative Research: De Novo Evolution of Multicellularity in a Unicellular Volvocine Alga study.
Page 74 from Darwin’s Notebook B: Transmutation.
Shortly after the return of the HMS Beagle to Cornwall, Charles Darwin jotted down the following note:
It is absurd to talk of one animal being higher than another.
In the subsequent twenty years, Darwin either forgot or reconsidered his note to himself.* He shouldn’t have.

A couple of weeks ago, I indulged in a little shameless self-promotion, writing about my new chapter on volvocine individuality in Biological Individuality, Integrating Scientific, Philosophical, and Historical Perspectives. Now two graduate students in the Michod lab at the University of Arizona, Erik Hanschen and Dinah Davison, have published their own take on volvocine individuality in Philosophy, Theory, and Practice in Biology (“Evolution of individuality: a case study in the volvocine green algae“). The article is open-access, and Hanschen and Davison are listed as equal contributors.
Jim Umen, the lead organizer of the upcoming Volvox meeting, has written a section for a new paper in BMC Biology, “Non-model model organisms.” Like all of the BMC journals, BMC Biology is open access, so you can check out the original.
The article surveys organisms that, while not among the traditional model systems, have been developed as model systems for studying particular biological questions. The paper has an unusual format, with a discrete section devoted to each species, each written by one or two of the authors. Aside from Volvox, there are sections on diatoms, the ciliates Stentor and Oxytricha, the amoeba Naeglaria, fission yeast, the filamentous fungus Ashbya, the moss Physcomitrella, the cnidarian Nematostella, tardigrades, axolotls, killifish, R bodies (a bacterial toxin delivery system), and cerebral organoids (a kind of lab-grown micro-brain).
Dr. Umen presents Volvox and its relatives as a model system for understand the evolution of traits related to the evolution of multicellularity:

If you’re a grad student or postdoc planning to attend the Fourth International Volvox Conference, don’t forget that travel grant applications are due this Saturday.
