Most bacteria, including many bacterial pathogens, are surrounded by an outer protective layer of sugar molecules, known as a ...

Experiments reveal that unsaturated lipid membranes promote vesicle fusion and DNA retention during freeze–thaw cycles, highlighting icy environments as potential drivers of protocell evolution. Today ...

A biomimetic synapse built from water droplets and biological ion channels achieves synaptic plasticity and performs machine learning tasks.

Extracellular vesicles (EVs) are tiny membrane-bound particles released by cells to transport proteins and other molecules to neighboring cells. Because of this natural delivery ability, EVs have ...

Mitochondria possess their own mRNA translation system, mediated by specialized mitoribosomes. Dysregulation of mitochondrial translation disrupts metabolic homeostasis and is linked to various ...

Therapeutic targeting of the AhR-Siglec-15 axis reveals potent efficacy against SHH medulloblastoma in preclinical models.

From molecular chaperones to mitochondrial failure, discover how heat reshapes the human transcriptome and drives the biological cascade that links rising temperatures to organ injury and public ...

Siglec-15 has traditionally been understood as an immune checkpoint molecule, primarily located on the cell membrane where it suppresses T-cell function. However, the new research revealed that in SHH ...

Studies show aging men often lose the Y chromosome in some cells, a change now linked to heart disease, cancer, and shorter ...

Scientists call this speck LUCA — the Last Universal Common Ancestor. Since the concept of LUCA first emerged, it has ...

Living organisms share an ancestor called the last universal common ancestor, or LUCA. LUCA is estimated to have lived ...

Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male ...
