Webb’s mysterious little red dots may be hiding entire galaxies
The James Webb Space Telescope has revealed that "little red dots" observed in the early universe may be bright galactic cores surrounded by spiral galaxy structures. Simulations showed that when the Saguaro galaxy is viewed from greater distances, its spiral arms disappear from view, leaving only the bright red center visible.

Tissue-resident memory T cells can sense physical touch through mechanical forces, not just biochemical signals. This mechanosensing ability, discovered by McGill University researchers, shapes how these immune cells develop long-term immunity in tissues.
Molecular electromagnetic sensor may enable remote-controlled gene therapy
Researchers developed a molecular electromagnetic sensor that uses DNA regulatory elements as gene switches for potential therapeutic applications. The sensor enables noninvasive control of gene expression in living organisms, particularly for treating genetic disorders through remote activation mechanisms.
