The Bisson Lab at IU (bissonlab.com) is hiring makers/builders/engineers across all career stages to join our team in one of the most exciting and crazy projects I've set to work on. Candidates can email us: [email protected] More info in the thread [1/3]

Supported by @hypothesisfund.bsky.social, we are developing new technologies to image microbes "in natura" across phases of salt brine, crystal, and liquid environments that can be deployed in the field under salty/dusty/hot conditions. [2/3]

We're specifically looking for someone who has built things and loves crazy projects than any particular degree/background. In this position, you'll work both in the Great Salt Lake (Utah) and at IU constructing synthetic salt lake "playas". Please spread the word! [3/3]

🚨 Archaea alert 🚨!! We’re back this Wednesday, April 22nd, at 10 AM EST / 4 PM CET with two exciting research talks! You won’t want to miss this so check your email for the Zoom link or visit the link in our bio for more info on how to join the community 🦠

Jack Szostak "All of these things frighten me, and they should frighten you as well. I made the decision to create a life for myself here, because I viewed this as a place that rewarded determination, hard work, and integrity. It still has a chance to be that place again."

If we find a novel organism branching between protists and animals, is it a #protist or an #animal? 🤔 We here suggest that if it has 3 cell types, a polarized outer layer, a feeding opening, and responsive behavior, then it is an animal! link.springer.com/article/10.1...

This is kinda bonkers. In addition, 20 amino acids were found on Ryugu, along with uracil and vitamin B3. These have been found in other instances, but since the samples from Ryugu were collected directly from the asteroid and delivered in sealed capsules, contamination on Earth could be ruled out.

I have a new review out in TiG titled, “The ecology of horizontal gene transfer”! I’ve been thinking about these ideas for years and this field is growing so fast it’s becoming impossible to review it. I hope this paper sparks discussion on different ways we can look at DNA transfer!

Having a hard time keeping up with the fast-moving field of origin of eukaryotes/Asgards archaea? Our new perspective article can help, we review the status of research over the last decade and where it's going. The archaeal roots of eukaryotic life www.pnas.org/doi/10.1073/...

Methanobrevibacter smithii is consistently associated with colorectal cancer. This has been confirmed by various studies, across numerous cohorts, including this recent one by our Lab @medunigraz.at www.nature.com/articles/s41...

I look at these kinds of protists ALL THE TIME. I have never seen them in situ like this. One cell. Absolutely remarkable. #protistsonsky

I'm thankful to MBE for publishing this paper. I wan't sure anybody would. The handling editor (I now know was Jeff Townsend) was great, as were the 2 reviewers. It is not an outcome/product/discovery, it is my way of thinking about HGT & pangenomes 1/3 academic.oup.com/mbe/article/...

My group at Science has been running a big campaign to engineer new channelrhodopsins. Excited to share the first results from it today: a suite of highly sensitive new opsins. We call them "WAChRs". Everyday indoor office lighting is enough to activate them pretty strongly.

With Eugene Koonin, we propose a concept of “the selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268

New paper from my team detailing a greatly expanded genomic database of Asgard archaea revealing of high energy metabolism those related to eukaryotes! Led by @katyappler.bsky.social lots of help from @jameslingford.bsky.social @valdeanda.bsky.social @kassipan.bsky.social doi.org/10.1038/s415...

One of the biggest questions in biology is how complex cells evolved about 2 billion years ago. Here's my new story on how scientists are solving the mystery of eukaryotes like us. Gift link: nyti.ms/4qMbo22

The 'devil is in the details'. You have to look beyond author claims and try to understand why the various studies have come to different conclusions and read the explanations given by the authors themselves.

Our latest preprint: Together with the team of Jan Löwe, @danieltamarit.bsky.social and many others we discovered and characterized several Asgard tubulin genes and propose that microtubule architecture and dynamics evolved in Asgard archaea prior to eukaryogenesis www.biorxiv.org/content/10.6...

Recently, a Hypothesis was posed in @jcellsci.bsky.social in which the root of eukaryotes was placed between kinetoplastids and all other eukaryotes. From this, it was implied that LECA did not have a kinetochore. We argue this is highly unlikely. A 🧵(1/12) Read our reply here: tinyurl.com/n87myhpr

Mitosis has a timing system. If chromosomes attach properly, cells divide on schedule and keep proliferating. If attachment is slow or incomplete, the delay is recorded — and daughter cells stop dividing. We explore this link in our new preprint. 🔗 www.biorxiv.org/content/10.6...
