The hidden role of the Milky Way in ancient Egyptian mythology      (via sciencedaily.com)     Original source 

Astrophysicists shed light on the relationship between the Milky Way and the Egyptian sky-goddess Nut. The paper draws on ancient Egyptian texts and simulations to argue that the Milky Way might have shone a spotlight, as it were, on Nut's role as the sky. It proposes that in winter, the Milky Way highlighted Nut's outstretched arms, while in summer, it traced her backbone across the heavens.

In the evolution of walking, the hip bone connected to the rib bones      (via sciencedaily.com)     Original source 

A new reconstruction of the 375-million-year-old fossil fish Tiktaalik -- a close relative of limbed vertebrates -- used micro-CT to reveal bones still embedded in matrix. The reconstruction shows that the fish's ribs likely attached to its pelvis, an innovation thought to be crucial to supporting the body and for the eventual evolution of walking.

NASA's Webb probes an extreme starburst galaxy      (via sciencedaily.com)     Original source 

A team of astronomers has used NASA's James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star formation activity. For comparison, M82 is sprouting new stars 10 times faster than the Milky Way galaxy.

When did the chicken cross the road? New evidence from Central Asia      (via sciencedaily.com)     Original source 

An international team of scholars present the earliest clear archaeological and biomolecular evidence for the raising of chickens for egg production, based on material from 12 archaeological sites spanning one and a half millennia. The research indicates that the domestic chicken, now a staple in diets around the world, is not as ancient as previously thought.

Ancient DNA reveals the appearance of a 6th century Chinese emperor      (via sciencedaily.com)     Original source 

What did an ancient Chinese emperor from 1,500 years ago look like? A team of researchers reconstructed the face of Chinese Emperor Wu of Northern Zhou using DNA extracted from his remains. The study suggests the emperor's death at the age of 36 might be linked to a stroke. It also sheds light on the origin and migration patterns of a nomadic empire that once ruled parts of northeastern Asia.

Persian plateau unveiled as crucial hub for early human migration out of Africa      (via sciencedaily.com)     Original source 

A new study combining genetic, palaeoecological, and archaeological evidence has unveiled the Persian Plateau as a pivotal geographic location serving as a hub for Homo sapiens during the early stages of their migration out of Africa. It highlights the period between 70,000 to 45,000 years ago when human populations did not uniformly spread across Eurasia, leaving a gap in our understanding of their whereabouts during this time frame.

Scientists find one of the most ancient stars that formed in another galaxy      (via sciencedaily.com)     Original source 

The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your veins and the calcium in your teeth and the sodium powering your thoughts were all born in the heart of a long-dead star.

New archive of ancient human brains challenges misconceptions of soft tissue preservation      (via sciencedaily.com)     Original source 

A new study has challenged previously held views that brain preservation in the archaeological record is extremely rare. The team compiled a new archive of preserved human brains, which highlighted that nervous tissues actually persist in much greater abundances than traditionally thought, assisted by conditions that prevent decay.

Largest-ever map of universe's active supermassive black holes released      (via sciencedaily.com)     Original source 

Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe's brightest objects. The new map logs the location of about 1.3 million quasars in space and time, the furthest of which shone bright when the universe was only 1.5 billion years old. The work could help scientists better understand the properties of dark matter.
