Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Task-specific odorant receptor expression in worker antennae indicates that sensory filters regulate division of labor in ants

open access: yesCommunications Biology, 2023
Division of labor (DOL) is a characteristic trait of insect societies, where tasks are generally performed by specialized individuals. Inside workers focus on brood or nest care, while others take risks by foraging outside.

Sex Speeds Adaptation by Altering the Dynamics of Molecular Evolution

open access: yesNature, 2016
Sex and recombination are pervasive throughout nature despite their substantial costs. Understanding the evolutionary forces that maintain these phenomena is a central challenge in biology.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Molecular Clouds: Internal Properties, Turbulence, Star Formation and Feedback

open access: yes, 2012
All stars are born in molecular clouds, and most in giant molecular clouds (GMCs), which thus set the star formation activity of galaxies. We first review their observed properties, including measures of mass surface density, Sigma, and thus mass, M.

Atomistic Dynamics of the Richtmyer-Meshkov Instability in Cylindrical and Planar Geometries [PDF]

open access: yes, 2006
We apply molecular dynamics (MD) simulations to study the evolution of the shock-driven Richtmyer-Meshkov instability (RMI) in the cylindrical and planar geometries.

The Diversity and Molecular Evolution of B-Cell Receptors during Infection

open access: yesMolecular biology and evolution, 2016
B-cell receptors (BCRs) are membrane-bound immunoglobulins that recognize and bind foreign proteins (antigens). BCRs are formed through random somatic changes of germline DNA, creating a vast repertoire of unique sequences that enable individuals to ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

El origen de la vida y la primera molécula capaz de replicarse a sí misma

open access: yesRevista de Química, 2014
El origen de la vida en la Tierra es una de las preguntas más difíciles presentadas a la ciencia. En los últimos 60 años, ha habido un progreso considerable en entender cómo moléculas relativamente sencillas, que son relevantes para la vida, pueden ser ...

Evolution of interstellar dust and stardust in the solar neighbourhood

open access: yes, 2007
The abundance evolution of interstellar dust species originating from stellar sources and from condensation in molecular clouds in the local interstellar medium of the Milky Way is studied and the input of dust material to the Solar System is determined.
