Tiny 1.7-billion-year-old fossils could reveal how complex life began
Scientists discovered tiny fossils in 1.7-billion-year-old rocks that could explain how simple microbial life evolved into complex organisms like plants and animals. Understanding this transition may help determine whether complex life could develop on other planets.

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.
