Investigadoras pioneras en biología de plantas 2025 - SEBP - Sociedad Española de Biología de Plantas El pasado 1 de julio, en el marco de la celebración del 50º aniversario de la SEBP, nuestra sociedad rindió homenaje a las investigadoras pioneras en Biología de Plantas Montserrat Pagès y Salomé Prat...

Con motivo del día internacional de las mujeres y las niñas en ciencia, recupero esta iniciativa que tuvimos en la SEBP, esperando a que se consolide. Feliz día.

La LOSU estableix que les universitats han de dotar-se d’un nou Estatut per complir la seva missió. Aquest matí, la UB ha aprovat el seu nou Estatut, després d’un procediment molt rigorós i altament participatiu. Una jornada històrica, en directe per UBtv www.ub.edu/ubtv/index.p...

Polyamines are natural compounds present in all living organisms. You have polyamines, too.

The door to the main lecture hall of the Max Planck Institute for Plant Breeding Research. Above the black wooden door are metallic letters showing the new name of the hall: "Jeff Schell Lecture Hall".

A photo of the front wall inside the lecture theatre at the Max Planck Institute for Plant Breeding Research. A large plant is in the middle of the picture. To the left of the plant are two busts of the heads of Max Planck and Erwin Bauer. To the right of the plant is a portrait of Jeff Schell.

Today, Director @raphmercier.bsky.social officially announced the new name of the main lecture hall at the MPIPZ Cologne:
"Jeff Schell Lecture Hall"

If you're wondering how Jeff earned the honor, have a look at my Short History of Plant Transformation:

Our latest @pnas.org! Preventing inappropriate signals pre- and post-ligand perception by a toggle switch mechanism of the plant receptor kinase ERECTA.

Its unique C-terminal alpha-helix domain inhibits the receptor active state. Congrats, all!🌱🥰

The latest version of Activity Metabolomics and Mass Spectrometry (AMMS 2025) is now in the proof stage. AMMS 2025 has two new chapters, lipids, and a lot of polishing. Still free as a PDF, and as royalty-free print version on Amazon.
Coming as soon as we get the proofs (and are happy with them).

Imagine how this will be in 50 years

Dear reviewers. Reviewing is not writing a wishing list of impossible workload. I never did that.

Capturing carbon from the air #Nature

"The new porous material for capturing carbon dioxide, called a covalent organic framework, has hexagonal channels decorated with polyamines that efficiently bind carbon dioxide molecules at concentrations found in ambient air."
