Researchers use real data rather than theory to measure the cosmos

A team from Imperial College London and University of Barcelona used astronomical surveys to measure the baryon acoustic oscillation scale, a standard distance central to the universe's expansion. The study suggests current methods for measuring distance are more complicated than needed, offering a data-driven approach to cosmology.

Earth's most abundant mineral finally has a name

Researchers have identified Bridgmanite, a high-density magnesium iron silicate mineral, as the most abundant mineral in Earth. The discovery was made possible by non-destructive micro-focused X-rays and novel fast-readout area-detector techniques, which allowed for the characterization of natural Bridgmanite for the first time.

New theory suggests alternate path led to rise of the eukaryotic cell

A new theory suggests that eukaryotic cells arose from external bacterial infections, where blebs trapped mitochondria-like bacteria, leading to the formation of complex cell structures. This alternative view challenges the current theory and offers a radical rethinking of how complex life came to be.
