The CMB: The most important discovery in cosmic history | By Ethan Siegel | Start with an explosion! | February 2025

This composite image shows the microwave sky according to the three generations of spatial CMB missions: Cobe (1990), WMAP (2000) and Planck (2010). Over time, we have become more sensitive to the temperature of lower magnitude and the polarization characteristics at progressively smaller angular scales.

G-quadruplexes reveal molecular links between telomeres and telomerase: critical findings for neoplastic transformation, aging and regenerative therapy

Normal cells age and eventually die when they have reached their maximum useful life. In these cells, telomeres, the end of a chromosome, cannot be synthesized due to the suppression of the inverse transcriptase enzyme of human telomerase (HTERT), resulting in the shortening of telomeres. Although the link is not clear yet, many studies showed…

Fossil of 149 million years pushes the origins of birds to the Jurassic period

A recent fossil finding fills a breach of obvious prehistoric birds. The Jurassic period affirms Archeptérix (Sometimes called Dinosaur Adeinonychosaurian), which, despite its feathered wings, seem more dinosaurs. Meanwhile, most Avian parents of the Cretaceous seem more similar to birds, with short tails that end in a compound bone called Pigostilo. A team from the…

The mysterious cosmic lights turn out to be 2 remains of Supernova without discovering

When the scientists pointed to the X-ray Observatory of the European Space Agency, XMM-Newton, with two mysterious lights on the outskirts of the great Magellanic cloud, they discovered an unexpected source: two previously unknown supernova remains. “When a star dies, it can explode in a supernova, causing a strong shock wave and forming an interstellar…
