Lately we have been working on the interactions of
#lichens
and
#mites
. This has been super exciting and the first two publications with our findings are now out. Here a quick summary (thread).

#Lichens
form their complex thalli through a partnership involving at least a fungus and an alga. But can these living structures be rebuilt in vitro? For more than a century, people have tried. With
@spribille.bsky.social
we revisited 150 years of
#lichen
#resynthesis
to ask: has anyone succeeded?

In honor of
#OzzyOsbourne
(RIP) my daughter & I went out to
#YoloBypass
to see the bats. And though the bats may have thought they were safe with Ozzy gone, it seems Ozzy was resurrected as either a Swainson's Hawk or peregrine falcon because they were out there snatching and eating bats.

We are wrapping up the 4th edition of our course Reproducibility in Bioinformatics! A big thank you to Christoph, Philipp and all participants for the great discussions, hands-on sessions, and commitment to making bioinformatics more reproducible Looking forward to the next one! 🚀

Okay, now this is wild - You can expose a desert lichen Clavascidium lacinulatum to UVC radiation for 3 months, at same dose that kills Deinococcus radiodurans, the most radiation-resistant bacteria, in 60 sec - and it survives! Lichens rock!

UVC-Intense Exoplanets May Not Be Uninhabitable: Evidence from a Desert Lichen | Astrobiology
Many of the recently discovered Earth-like exoplanets are hosted by M and F stars, stars that emit intense UVC, especially during a flare. We studied whether such planets are nevertheless habitable by irradiating a desert lichen, Clavascidium lacinulatum, with 254-nm 55 W/m2 UVC nonstop for 3 months in the laboratory. Only 50% of its algal photobiont cells were inactivated. To put this in perspective, we used the same setup to challenge the photobiont cells but grown in pure culture, and Deinococcus radiodurans, the most radiation-resistant bacterium on Earth. Entire monolayers of hundreds of cells were inactivated in just 60 s. Further studies indicated that the cortex of the lichen was rendered UVC-opaque by deposits of phenolic secondary metabolites in its interstices. The lichen was injured only because, while most photochemical reactive oxygen species were quenched, photochemical ozone was not. We conclude that UVC-intense exoplanets are not necessarily uninhabitable to photosynthetic organisms.

Excited to see the German translation of our book “Lives of Lichens” now available for preorder. And a switch-up of the cover photo: this time Rusavskia elegans from Montana!
add a skeleton here at some point

NIH funding supporting the HMMER and Infernal software projects has been terminated. NIH states that our work, as well as all other federally funded research at Harvard, is of no benefit to the US.
