Distinct ATRX functions cooperate with 9-1-1 and CST complexes to safeguard replication and telomere integrity Mutations in the ATRX chromatin remodeller predispose to a developmental genetic disorder and cancer, but how it safeguards genome and telomere stability remains unresolved. Here, we uncover critical ...

Genomic resistance in historical clinical isolates increased in frequency and mobility after the age of antibiotics Antibiotic resistance is frequently observed shortly after the clinical introduction of an antibiotic. Whether and how frequently that resistance occurred before the introduction is harder to determin...

What was antibiotic resistance like before we ever used antibiotics? How did we change what antibiotic resistance genes looked like over 100 years?

Opinion | Spain Is an Example to the World

NYT: “Spain is proving an important point: A generous immigration policy is not a threat to the nation or to a thriving economy. More than that, it is a resource for growth and renewal that Spain’s peers spurn at their cost.” www.nytimes.com/2025/08/11/o...

Hi, are you an academic biology lab in the Boston area? I am a lab manager at a local biotech and I will be getting rid of a lot consumables in the near future (as will many of my colleagues, unfortunately). If you would be interested in free consumables, please reach out to me!

Life finds a way

That's great! Congrats!

This wouldn't have been possible without the many mentors and colleagues that I have accumulated over the years, I feel so much gratitude to you all. Now, time to do the work and get some cool data!

It feels wild to post this, given the state of things, but I just got the NoA for my first NIH grant ever, a K99/R00 award from the NIEHS! I will be studying the role of bacterial error-prone DNA polymerases in mutagenesis and the evolution of antibiotic resistance.

I’m so happy to share a project very close to my ❤️ launching this September: Atlas de Científicxs Latinoamericanxs que Inspiran ✨
We’re currently collecting nominations!
This atlas spotlights researchers from LATAM who trained in the North & returned home to lead labs. Here’s why this matters 🧵👇

Una selectividad más compleja no logra bajar las desorbitadas notas de acceso a la universidad El número de solicitudes ha vuelto a crecer, aumentando la competencia, de forma que el ingreso está al alcance de pocos en muchos grados

Creo que estamos confundiendo a nuestra juventud con una oferta a todas luces excesiva de grados con nombres a cual más atractivo, cuando en realidad deberíamos apostar por grados genéricos y transversales, dejando la especialización para el máster y tesis. #biología 💪

Recognizing the importance of language accessibility in science and scientific communication, I have translated this work into Spanish. You can find the Spanish translation in Supplementary file 3!

Bacteriophage infection drives loss of β-lactam resistance in methicillin-resistant Staphylococcus aureus In methicillin-resistant Staphylococcus aureus, evolution of bacteriophage resistance causes trade-offs that re-sensitize the bacteriato β-lactam antibiotics.

I'm excited to announced that the version of record of this article is out in @elife.bsky.social. With the other first coauthor My Tran, we found that phage resistance cause reduced beta-lactam resistance and reduced virulence phenotypes in diverse MRSA strains.

¡Muchas gracias!👏

Vanderbilt University Medical Center to lay off up to 650 after Trump administration grant cuts • Tennessee Lookout Vanderbilt University Medical Center, expects to lay off 650 employees as a result of grant and funding cuts by the Trump Administration,

Vanderbilt University Medical Center, one of the largest academic research and hospital care systems in the southeast, expects to lay off 650 employees as a result of grant and other funding cuts made by the Trump Administration, it said in a statement. From @anitawadhwani.bsky.social.

A collage featuring materials related to the 1925 Scopes Trial. The main panel reads “1925 Scopes Trial” with a brief description of the trial’s origins in Dayton, Tennessee. Two historic newspaper clippings are overlaid. One headline reads “Science Academy’s Brief Quotes Two Vandy Professors,” referring to their support of evolution in the trial. Another reads “Evolution Bill Backward Step,” noting Dr. E.E. Reinke of Vanderbilt opposing anti-evolution legislation.

A collage of clippings and photos related to Scopes Trial history. At top left, a photo of John Scopes and Clarence Darrow in 1925. At top right, a man points to the Tennessee historical marker for the Scopes Trial. Center right is a newspaper article announcing Scopes’ 1960 talk at Peabody College. Bottom left features a poster for a 2005 play adaptation starring Ed Asner and John de Lancie, based on the Scopes Trial. Bottom right is a continuation of a newspaper article discussing free speech and minority rights, referencing Vanderbilt events and speakers.
