Many biological functions are regulated by the switching on and off of mechanisms triggered by the matching of a keyhole (receptor) formed by a protein’s three-dimensional structure and a molecule (ligand) that fits perfectly into […]

Researchers from the National University of Singapore (NUS) have developed CellScope, a high-performance single-cell analysis framework that uses manifold fitting to analyze single-cell RNA sequencing (scRNA-seq) data. This framework helps build detailed “cell atlases” that […]

How much will heat, flooding, drought and storms increase as a result of human-induced climate change? In a groundbreaking study, climate researcher Gottfried Kirchengast and his team at the University of Graz have developed a […]

Most countries will not achieve climate neutrality through greenhouse gas emission reductions alone; carbon sinks are also needed to offset unavoidable emissions. Researchers are discussing technical solutions, such as applying silicate-rock powder to arable land. […]
