Pacific cities much older than previously thought      (via sciencedaily.com)     Original source 

New evidence of one of the first cities in the Pacific shows they were established much earlier than previously thought, according to new research. The study used aerial laser scanning to map archaeological sites on the island of Tongatapu in Tonga, showing Earth structures were being constructed in Tongatapu around AD 300.

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.

Subterranean storage of hydrogen      (via sciencedaily.com)     Original source 

Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.

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.

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.

The atlas of unburnable oil in the world      (via sciencedaily.com)     Original source 

In order to limit the increase in global average temperature to 1.5 C, it is essential to drastically reduce carbon dioxide emissions in the atmosphere. This would mean not exploiting most of the existing coal, conventional gas and oil energy resources in regions around the world, according to new research. The study presents the atlas of unburnable oil in the world, a world map designed with environmental and social criteria that warns which oil resources should not be exploited to meet the commitments of the Paris Agreement signed in 2015 to mitigate the effects of climate change.
