Collisions of high energy particles produce “jets” – quarks, antiquarks, or gluons moving through the quantum vacuum. Due to the confinement property of strong interactions, quarks are never directly detected but instead fragment into many secondary particles. Scientists have long expected that as jets propagate through the confining quantum vacuum, they will modify that vacuum […]
Source: Zhang et al. (2023) Despite their importance in our daily lives, we do not give much importance to our hands or feet, and even less at how they came to be. Even if roughly known, the process of human limb development had never been observed at single cell level resolution. Recently, Sarah Teichmann and […]
Author: Ramón Muñoz-Chápuli has been Professor of Animal Biology in the University of Málaga until his retirement. He has investigated for forty years in the fields of developmental biology and animal evolution. On October 11th, I published an article on Mapping Ignorance about the microbial dark matter, the vast diversity of microorganisms that cannot be […]

“Censorship” is not a pleasant word to anyone. Its connotations are almost always negative and, in the first instance, an effort should be made to find circumstances that justify a restriction of information. Even more so in the scientific field, where empirical evidence should prevail over authority, tradition, rhetorical eloquence or social prestige. Science seeks […]
Deep below the Spanish side of the Pyrenees, we find the LSC (Laboratorio Subterráneo de Canfranc – Canfranc Underground Laboratory), where the NEXT experiment is taking place. Its goal is one of the remaining holy grails of particle physics: the proof that the neutrino is its own antiparticle, a result with profound meaning not only […]
To eat, a cell needs to carry its main nutrients (sugars, lipids, and peptides –pieces of proteins–) across the cell membrane. To do so, it has a number of molecular transporters. Interestingly, although sugar transporters are highly specific to the type of sugar they transport, peptide transporters are not picky at all. This promiscuity has […]
Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission. Currently he is a researcher of the UPV/EHU. He investigates the role of stem cells in physiologic and pathologic conditions. Solid cancerous tumor is a […]

Sensors are essential tools for detecting and analysing trace molecules in a variety of fields, including environmental monitoring, food safety, and public health. However, developing sensors with high enough sensitivity to detect these tiny amounts of molecules remains a challenge. One promising approach is surface-enhanced infrared absorption (SEIRA), which uses plasmonic nanostructures to amplify the […]
T-cell acute lymphoblastic leukemia (T-ALL) is a hematological malignancy that affects both children and adults. Although with current chemotherapy regimens cure is achieved in ~80% of pediatric patients, adults fare more poorly with only 40% 5-year overall survival . Restricted cellular subsets with asymmetrically enriched leukemia-initiating cell (LIC) activity have been reported in human and […]
In their recent paper “Telling Gender: The Pragmatics and Ethics of Gender Ascriptions” , the philosophers Quill Kukla and Mark Lance (well known in the philosophy of language as authors of the 2009 essential book Yo! And Lo! The Pragmatic Topography of the Space of Reasons ) embark on a journey into the heart of […]
