300,000-year-old genomes: History of the Schöningen horses deciphered

For the first time, a research team from the Senckenberg Center for Human Evolution and Paleoenvironment at the University of Tübingen and the Schöningen Research Center have reconstructed the genomes of an extinct horse species, Equus mosbachensis, from the archaeological site of Schöningen in Lower Saxony, which is approximately 300,000 years old.

Thanks to exceptionally favorable preservation conditions, the researchers were able to identify the oldest DNA yet discovered from an open-air site. Their analyses show that the Schöningen horses belong to a lineage that is considered to be the origin of all modern horses. The study is published in the journal Nature Ecology & Evolution.

Domestic and , donkeys and zebras all belong to the sole genus of the family Equidae still in existence today. But a look into the shows that more than 35 different genera and hundreds of now extinct equine species occurred throughout the past.

SCP-022 Explained: The Morgue That Breaks Science (Speculative Science Deep Dive)

SCP 22, known as The Morgue, is one of the most chilling and mysterious anomalies in the SCP Foundation archives. A simple hospital basement in Great Britain became the stage for an impossible phenomenon: cadavers rising without life, objects vanishing into nowhere, and a morgue that behaves less like a room and more like a machine.

In this speculative science deep dive, we explore SCP 22 through the lenses of biology, physics, and consciousness. Could these reanimated cadavers be powered by quantum vacuum energy? Is the morgue recycling entropy across dimensions? Or is it a misunderstood mechanism that uses humans as raw material for unknown purposes?

This essay-video blends science, philosophy, and horror to uncover the enigma of SCP 022.

Infrared data from the James Webb Telescope reveals more structural details of M87’s black hole jet

Scientists have long been aware of the massive elliptical galaxy, M87. The galaxy was first observed in the late 18th century by Charles Messier, who cataloged objects in the sky specifically to avoid them when looking for comets. However, numerous later observations in the radio, X-ray, optical, UV, and gamma-ray bands revealed that the object is a galaxy with a prominent jet emerging from a supermassive black hole at its core. This jet is now well known for its synchrotron emission in the radio to optical wavelengths.

Although many observations have been made on M87, data had been somewhat lacking in the . But now, a group of scientists have utilized new data from the James Webb Space Telescope (JWST) and its near infrared cameras (NIRCam) to resolve some previously fuzzy details about M87’s jet. The work is now published in the journal Astronomy & Astrophysics.

The JWST+NIRCam images were taken in four infrared bands at 0.90, 1.50, 2.77, and 3.56 µm. In order to isolate the light coming from the actual jet, the team used background subtraction methods, calibration, and galaxy modeling to remove light from stars, galactic dust, background , and globular clusters. This revealed a detailed infrared picture of the main jet, as well as the counter-jet, which points in the opposite direction coming out from the black hole.
