What pottery reveals about prehistoric Central European culinary traditions      (via sciencedaily.com)     Original source 

The analysis of fat traces in over one hundred pottery vessels reveals deep changes in food consumption and preparation by communities living in central Germany between the Early Neolithic and the Late Bronze Age, as well as in their relation with innovations in pottery styles and decorations. In a groundbreaking study, researchers identified a generalized inclusion of dairy products in prehistoric diets, a preference in consuming pork with the arrival of communities from the Eurasian Steppe, and the importance of dairy products in funeral rites. Central Germany was a key region for the emergence of great prehistoric cultures, such as the Linear Pottery Culture, the Corded Ware Culture, the Bell Beaker populations and the Unetice Culture, one of the first state societies in Europe.

Evolutionary history of extinct duck revealed      (via sciencedaily.com)     Original source 

The study's findings show mergansers arrived in the New Zealand region at least seven million years ago from the Northern Hemisphere, in a separate colonisation event to that which led to the Brazilian merganser.

Early arrival and expansion of palaeolithic people on Cyprus      (via sciencedaily.com)     Original source 

The patterns of dispersal of early humans across continents and islands are hotly debated, but researchers have found that Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought. In examining the timing of the first human occupation of Cyprus, research found that large islands in the Mediterranean Sea were attractive and favorable destinations for palaeolithic peoples. These findings refute previous studies that suggested Mediterranean islands would have been unreachable and inhospitable for Pleistocene hunter-gatherer societies.

Toxic chemicals can be detected with new AI method      (via sciencedaily.com)     Original source 

Researchers have developed an AI method that improves the identification of toxic chemicals -- based solely on knowledge of the molecular structure. The method can contribute to better control and understanding of the ever-growing number of chemicals used in society, and can also help reduce the amount of animal tests.

New computer algorithm supercharges climate models and could lead to better predictions of future climate change      (via sciencedaily.com)     Original source 

A study describes a new computer algorithm which can be applied to Earth System Models to drastically reduce the time needed to prepare these in order to make accurate predictions of future climate change. During tests on models used in IPCC simulations, the algorithm was on average 10 times faster at spinning up the model than currently-used approaches, reducing the time taken to achieve equilibrium from many months to under a week.

More plants on the menu of ancient hunter-gatherers      (via sciencedaily.com)     Original source 

It has long been thought that meat played an important role in the diet of hunter-gatherers before the Neolithic transition. However, due to the scarcity of well-preserved human remains from Paleolithic sites, little information exists about the dietary habits of pre-agricultural human groups. A new study challenges this notion by presenting compelling isotopic evidence of a strong preference for plants among 15,000-year-old hunter-gatherers from Morocco. This is the first time a significant amount of plant consumption has been measured for a pre-agricultural population, shedding new light on the dietary practices of ancient human societies.

From disorder to order: Flocking birds and 'spinning' particles      (via sciencedaily.com)     Original source 

Researchers have demonstrated that ferromagnetism, an ordered state of atoms, can be induced by increasing particle motility and that repulsive forces between atoms are sufficient to maintain it. The discovery not only extends the concept of active matter to quantum systems but also contributes to the development of novel technologies that rely on the magnetic properties of particles, such as magnetic memory and quantum computing.

Ancient Maya blessed their ballcourts      (via sciencedaily.com)     Original source 

Using environmental DNA analysis, an international team of researchers identified a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah in Mexico. The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor where a ballcourt was built.

First evidence of human occupation in lava tube cave in Saudi Arabia      (via sciencedaily.com)     Original source 

New research has highlighted an area in Arabia that once acted as a key point for cultural exchanges and trades amongst ancient people -- and it all took place in vast caves and lava tubes that have remained largely untapped reservoirs of archaeological abundance in Arabia. Through meticulous excavation and analysis, the international team uncovered a wealth of evidence at Umm Jirsan, spanning from the Neolithic to the Chalcolithic/Bronze Age periods (~10,000-3,500 years ago).

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.
