Los investigadores y colaboradores de Mayo Clinic han identificado una proteína expresada en células inmunitarias que podría desempeñar un rol clave en el desarrollo de la esclerosis lateral amiotrófica (ELA), también conocida como enfermedad de Lou Gehrig. El equipo también descubrió que un tratamiento inmunomodulatorio que bloquea la proteína era capaz de restaurar la función motriz en modelos preclínicos. Los hallazgos indican que la proteína, conocida como integrina α5 (pronunciado integrina alfa 5), es un posible blanco terapéutico para la ELA.

The Matabele ants (Megaponera analis), which are widespread south of the Sahara, have a narrow diet: They only eat termites. Their hunting expeditions are dangerous because termite soldiers defend their conspecifics – and use their powerful mandibles to do so. It is therefore common for the ants to be injured while hunting.

With the rise in machine learning applications and artificial intelligence, it's no wonder that more and more scientists and researchers are turning to supercomputers. Supercomputers are commonly used for making predictions with advanced modeling and simulations. This can be applied to climate research, weather forecasting, genomic sequencing, space exploration, aviation engineering and more.
NEMO, a protein that is primarily associated with signaling processes in the immune system, prevents the deposition of protein aggregates that occur in Parkinson’s disease. For this purpose, it binds to certain protein chains that serve as markers for cellular waste removal, thus promoting the degradation of the harmful aggregates.
Researchers from Karlsruhe Institute of Technology (KIT) and partners all over Germany have developed a new system for X-ray imaging, which is suited for both living specimens and sensitive materials.
Cerebral organoids are three-dimensional, in vitro cultured brains that mimic the activities of the human brain. They have emerged as invaluable tools to comprehend evolution, disease pathogenesis, and neurodevelopmental processes. However, the development of these organoids is still in nascent stages with several limitations that hinder their broad applications. A major obstacle is the absence of a functional vasculature that can restrict the size of organoids, trigger cell death, and prevent cell differentiation in the organoids.
When plants are infected by pathogens, suffer from a lack of water or have to react to other external stimuli, the first thing they do is increase the proton and calcium concentration in the affected cells.

One of the greatest philosophical thought exercises that has challenged the concept of identity, is the Ship of Theseus paradox. It poses the question: Are we the same person over time? The original meaning of ‘Identity’ is derived from Medieval Latin identitas or idem meaning ‘sameness’ or ‘same’. But ‘sameness’ has been difficult to comprehend.

Researchers at the Icahn School of Medicine at Mount Sinai have identified an allergy pathway that, when blocked, unleashes antitumor immunity in mouse models of non-small cell lung cancer (NSCLC). And in an early parallel study in humans, combining immunotherapy with dupilumab—an Interleukin-4 (IL-4) receptor-blocking antibody widely used for treating allergies and asthma—boosted patients' immune systems, with one out of the six experiencing significant tumor reduction. The findings were described in the December 6 issue of Nature.
