A layered lake is a little like Earth’s early oceans − and lets researchers explore how oxygen built up in our atmosphere billions of years ago

" My colleagues and I have homed in on Deming Lake to explore questions about how microbial life adapted to and changed the environmental conditions on early Earth. Our planet was inhabited only by microbes for most of its history. The atmosphere and the oceans’ depths didn’t have much oxygen, but they did have a lot of iron, just like Deming Lake does. By investigating what Deming Lake’s microbes are doing, we can better understand how billions of years ago they helped to transform the Earth’s atmosphere and oceans into what they’re like now."

Research finds dramatic increase in cranial traumas as the first cities were being built, suggesting a rise in violence

 " The development of the earliest cities in Mesopotamia and the Middle East led to a substantial increase in violence between inhabitants. Laws, centralized administration, trade and culture then caused the ratio of violent deaths to fall back again in the Early and Middle Bronze Age (3,300 to 1,500 BCE). This is the conclusion of an international team of researchers from the Universities of Tübingen, Barcelona and Warsaw. Their  results  were published in  Nature Human Behaviour ." https://phys.org/news/2023-10-cranial-traumas-cities-built-violence.html

 " Initially hailed by its discoverers as “the most ancient Hebrew inscription ever found,” the  controversial Mt. Ebal curse tablet  may be no more than a common fishing weight. At least that is the suggestion of archaeologist Amihai Mazar, who published his interpretation of the artifact in the  Israel Exploration Journal , alongside two other articles skeptical of the discoverers’ claims."
