Congrats to @camolsan.bsky.social @aliciaperezlorente.bsky.social and colleges for this fantastic work.

Thanks for your visit and insightful discussion! 🙏

A nucleosome switch primes hepatitis B virus infection A reconstituted cccDNA platform facilitated the discovery of an early chromatinization event that promotes transcription of the hepatitis B virus (HBV) regulatory X gene. The use of a small-molecule c...

I am extremely proud to see our work about Hepatitis B now published in @cellpress.bsky.social

From basic research to identifying the key step of infection & a potential first drug for curing this devastating disease. This has been an incredible journey.🧵

An ancient woman from Romania shows an edgeto-edge bite (left). A Bronze Age man from Austria had a slight overbite (right). Hedline reads: Ancient switch to soft food gave us an overbite—and the ability to pronounce ‘f’s and ‘v’s

The spread of agriculture didn’t just change our diets—it altered our jaws as well, making it easy to pronounce "f"s and "v"s and opening a whole new world of words.

A novel regulation on the developmental checkpoint protein Sda that controls sporulation and biofilm formation in Bacillus subtilis | Journal of Bacteriology Genome-wide ribosome profiling in Bacillus subtilis shows that under serine limitation, ribosomes pause on the four TCN (N for A, C, G, and T), but not AGC/AGT serine codons, during translation at a g...

Well done Alicia. A wonderful piece work showing the complexity and beauty of microbial interactions.

The offensive role of the Bacillus extracellular matrix in driving metabolite-mediated dialogue and adaptive strategies with pathogenic fungi Bacterial□fungal interactions have traditionally been attributed to secondary metabolites, but the role of the bacterial extracellular matrix (ECM) in shaping these relationships has remained unclear....

Excited to share our latest preprint! A fascinating story of chemical dialogue and microbial warfare: the Bacillus extracellular matrix acts as a key driver in the antagonistic interaction with Botrytis, while the fungus mounts a multi-layered defense.

US health agency seeks to cut gender-related terms from scientific papers The mandate from the Centers for Disease Control and Prevention follows an executive order from president Donald Trump, and applies to research not yet published.

The US Centers for Disease Control and Prevention (CDC) has mandated that all scientific manuscripts produced by its researchers that are under review at a journal be withdrawn so that certain language relating to gender can be stripped from them.

Fine-tuning gibberellin improves rice alkali–thermal tolerance and yield - Nature Precise regulation of the phytohormone gibberellin to optimal levels may not only confer alkali–thermal tolerance to Green Revolution rice varieties but may also further enhance their yield, and ATT2, by enabling the fine-tuning of gibberellins, is expected to be a potential new post-Green Revolution gene.

Congratulations Montse. Very well-done and deserved.

Diversification of Lipopeptide Analogues Drives Versatility in Biological Activities Cyclic lipopeptides (CLPs) are potent secondary metabolites with diverse biological functions. Bacillus strains primarily produce CLPs of three key families, namely, iturins, fengycins, and surfactins...

Super happy to share my first article at @diegromero.bsky.social´s lab, about Bacillus cyclic lipopeptides and how the diversification of structural variants production impacts biological activities!!

Don’t be glum about the long, cold winter. Look around: the trees are busy, not sleeping. When the temperature permits, cells in this bud are dividing, maturing into flowers, leaves, stems. The cambium, maker of all the trees, is preparing for its spring festivities. Be like a tree: keep growing.

Elemental cryo-imaging reveals SOS1-dependent vacuolar sodium accumulation - Nature This study demonstrates that cryo nanoscale secondary ion mass spectrometry (CryoNanoSIMS) enables direct multi-elemental imaging at subcellular resolution of macro- and micronutrients or trace elements in plants and may provide insights into the in vivo roles of many transporters.

How seaweed could be used to make sustainable antibiotics A lab in Norway is working on a new method to make antibiotics by training bacteria to eat seaweed.

Our EU project iCULTURE is on BBC!!!!
Of course, we are not trying to producing classical antibiotics but #bacteriocins and other antimicrobial peptides to start with. But once this is achieved, anything is possible.
