Unpacking into our new house and I found this. Many happy evenings at He’s not. And many science discussions!

Ramón y Cajal investigator at the IPBLN-CSIC. My lab studies how bacteria mutate, evolve antibiotic resistance, and repair their DNA. Oviedo->Chapel Hill->Nashville->Granada. No hay que llegar primero, pero hay que saber llegar.
🧵 El verano de 2026 por ahora (junio-julio) es el más cálido de la serie histórica en España, que arranca en 1961. ➡️ Con una temperatura media de 24,5 ºC, supera en 0,7 ºC a los bimestres junio-julio más cálidos, los de 2022 y 2025. Es 2,9 ºC más cálido que el promedio 1991-2020.
To what extent is cancer development deterministic? Does the germline genome affect that predictability? We re-ran cancer evolution to answer these questions. www.nature.com/articles/s41...
Bienvenidas las #Plazas de investigación, los contratos #ATRAE, #RyC, etc. Pero si no se inyecta más dinero en el sistema, eso solo sirve para que se rechacen más proyectos. Y los que se conceden, se quedan con una financiación estancada desde hace 5 años, que no cubre siquiera la inflación. 😠
Y si queréis ver la tendencia de los últimos años: - Está subiendo mucho el número de solicitudes (casi un 10% respecto al año pasado). - La financiación total no sube al mismo ritmo (un 5,7%). - La financiación media por proyecto se mantiene. - Conclusión: se rechazan más proyectos.
Muchos ya habréis visto la resolución provisional de los proyectos #PID2025 de la @ageinves.bsky.social Aquí va la distribución. La financiación media por proyecto se ha quedado como el año pasado. Y seguimos con 2/3 de los proyectos con <50 k€ por año. ☹️ www.aei.gob.es/convocatoria...
Delighted to share that I’ll be sticking around at Michigan to start my lab in the Department of Human Genetics! Starting in May 2027, the Tovar lab will use functional genomics to study transcription factor biology and regulatory network dynamics in complex disease. Stay tuned for more details…
Chromosome loss is detrimental to cellular fitness, yet can be one of the earliest events in cancer. How can a deleterious genomic alteration initiate tumorigenesis? 🤔 Our latest preprint tackles this paradox using clear cell renal cell carcinoma (ccRCC) as a model. www.biorxiv.org/content/10.6...
A single chromosome 3p break initiates clear cell renal cell carcinoma evolution
Clear cell renal cell carcinoma (ccRCC) is initiated by chromosome 3p loss, yet chromosome losses impose a profound fitness burden on normal cells. How renal epithelial cells tolerate this deleterious...

Lo de Balogun es un escándalo tan grande como me parece, ¿no?
We teamed with Jim Crott's lab at BU to show that administration of freeze-dried Parabacteroides distasonis extends Drosophila mean lifespan by preventing leaky guts. How? Maybe hormesis. A fun collaboration that features the work of 8 Tufts undergraduates! www.aginganddisease.org/EN/10.14336/...
Lifelong Consumption of Freeze-Dried <i>Parabacteroides Distasonis</i> Improves Gut Barrier Integrity and Extends Lifespan and Health Span in Drosophila Melanogaster.
<p>Chronic inflammation has been shown to be associated with aging. In <i>Drosophila melanogaster</i>, age-related inflammation in the gut results in a disruption of gut barrier integrity, which can l...

Processing of reversed replication forks is required for the resolution of replication-transcription conflicts
Abstract. DNA replication and transcription occur simultaneously on the same template, leading to conflicts between the two machineries. Conflicts stall re

Third first-author and first (co-)corresponding author pre-print from my postdoc! In which we do a whole-genome transposon screen to determine how replication-transcription conflicts are resolved in Bacillus subtilis. Check out! www.biorxiv.org/content/10.6...
Join us! Postdoc position (2-3 years) in our lab @molbiolau.bsky.social Looking for candidates with experience in cell culture, genome editing, biochemistry, and/or structural biology. Application opens in August via AU's system but informal enquiries by email are welcome from now. (1/2)
Related: if you know a great undergrad interested in grad school (or if YOU are interested), & they'd like to work in fungal biology using population genomics to study pathogenicity and genome plasticity, please encourage them to reach out! See annehatmaker.com/contact/ for more info on how
I shared on LinkedIn already, but I wanted to post here as well since I've got a different audience: I will be joining the Department of Plant Pathology at the @universityofga.bsky.social as an Assistant Professor on Aug 1!! I will keep studying #Aspergillus & #Fusarium that infect plants & humans 🥰
Paper accepted!

Today is the last day of 11 magnificent years living in the United States. Today, I move back to Spain. I came as a 22 year old aspiring scientist and I’m coming back with a wonderful wife, and the best scientist I could become. And of course, with little Mango.

Carolyn started this as a whole-genome revisit of the classic 1996 papers on spontaneous nondisjunction from Hawley (Dros X) and Sherman (human 21) labs. She looked at a metacentric (Dros 2) and found that the rules are different - no obvious relationship between ndj and crossovers. Shape matters!
Carolyn Turcotte and @jeffsekelsky.bsky.social employed whole-genome sequencing to study spontaneous meiotic nondisjunction of the metacentric chromosome 2 in #Drosophila, identifying chromosome-specific mechanisms of meiotic nondisjunction. 🪰 Learn more in #GENETICS: 🔗 buff.ly/LmC3qZU
Last (?) preprint as a postdoc in the Merrikh lab! Awesome collaborative effort with graduate student Oyku! I hope people give it a read!

“Why argue with an Arsenal fan when you can just wait?” We waited. We won. We are champions of England - and we are just one game away from being crowned champions of Europe. Read my piece on what Arsenal means to me here: www.nytimes.com/athletic/731...
Excited to share our latest paper! We found that large pieces of the human genome can transfer between cells upon direct contact, endowing recipient cells with heritable phenotypic changes. @cp-cell.bsky.social (1/7) www.cell.com/cell/fulltex...

US universities genuinely are like “welcome to Tennessee Agricultural College in Bumfuck Nowheresville. We invented the modern potato and our facilities include a particle accelerator, nuclear reactor, and TOP500 supercomputer. Tuition is $12,000 for instate students and we have 40,000 of them”
Excited to drop our visual systems pre-print 10 years in the making. We hacked nature's cheat code to protect the eye from light damage. This unexpectedly also boosts rod sensitivity. Huge thanks to collabs Tonia Rex, @amandalea.bsky.social , Alex Bick, and their labs! @evolutionvu.bsky.social
