Did you know the American Southwest has been in a historic megadrought since the turn of the century? Drought severely impacts crops, causing stunted growth, leaf wilting, and reduced yields.
Salk plant scientists are working to find ways around these impacts, which have destroyed crop yields and farmer economic profits over the last 25 years. After profiling nearly a million cells from the leaves of Arabidopsis thaliana, they found that drought conditions accelerate leaf aging, but a specific gene—FRO6—could be used to rescue leaf growth during drought.
The study could inform the development of future crops that withstand droughts longer.

A unique Rubisco subunit from the hornwort plant carries a built-in extension that enables the enzyme to cluster into carbon-concentrating structures like algae, according to a new Science study—an innovation that successfully triggered similar condensates when introduced into Arabidopsis plants.
The findings reveal a novel and evolutionarily independent solution for Rubisco condensation in land plants and open the door for engineering similar systems in agricultural crops to potentially boost nutrient efficiency and yield.

AI is cool and all... but a new paper in @ScienceMagazine kind of figured out the origin of life?
The paper reports the discovery of a simple 45-nucleotide RNA molecule that can perfectly copy itself.
"… I reflected on how we train future scientists. Should we talk more openly with students about failure? When I quietly left research, frustrated at what felt like my lack of accomplishment, was this a typical experience? How often do we inadvertently discourage students from persisting in science, simply by omitting honest descriptions of the failure inherent to the research process? Research is messy and full of failed attempts. Trying to protect students from that reality does them a disservice."
On #InternationalDayOfEducation, take a look back at this Working Life essay on teaching students about scientific failure. https://t.co/CmiwjmRYq3

A paper in Nature presents a detailed map of human chromosomes within the nucleus. This resource provides a foundation for an improved understanding of how the physical layout of human DNA is associated with biological expression. https://t.co/ouE35wszsA
The Synthetic Yeast Genome Project (Sc2.0) set out to redesign and chemically synthesize an entire eukaryotic genome. In 2025, the final synthetic chromosome was completed, marking the culmination of more than a decade of iterative design and international collaboration. How will these findings shape the future of synthetic genomics? https://t.co/QCxxD9wNyr
