Researchers create lunar regolith bricks that could be used to construct Artemis base camp      (via sciencedaily.com) 

As part of NASA's Artemis program to establish a long-term presence on the moon, it aims to build an Artemis base camp that includes a modern lunar cabin, rover and mobile home. This fixed habitat could potentially be constructed with bricks made of lunar regolith and saltwater, thanks to a recent discovery.

Ancient bacteria might lurk beneath Mars' surface      (via sciencedaily.com) 

Scientists found that ancient bacteria could survive close to the surface on Mars much longer than previously assumed. So, if life did, in fact, evolve when the last waters flowed on Mars, it would likely still be there today -- billions of years later.

Biblical military campaigns reconstructed using geomagnetic field data      (via sciencedaily.com) 

Researchers reconstructed the geomagnetic fields recorded in 21 archaeological destruction layers throughout Israel and used the data to develop a reliable new scientific tool for archaeological dating. The new tool enables the verification of Old Testament accounts of the Egyptian, Aramean, Assyrian, and Babylonian military campaigns against the Kingdoms of Israel and Judah.

UK's oldest human DNA obtained, revealing two distinct Palaeolithic populations      (via sciencedaily.com) 

The first genetic data from Palaeolithic human individuals in the UK -- the oldest human DNA obtained from the British Isles so far -- indicates the presence of two distinct groups that migrated to Britain at the end of the last ice age, according to new research. Published today in Nature Ecology and Evolution, the new study by UCL Institute of Archaeology, the Natural History Museum and the Francis Crick Institute researchers reveals for the first time that the recolonisation of Britain consisted of at least two groups with distinct origins and cultures.

Skaftö wreck's cargo tells a tale of 15th century trade routes      (via sciencedaily.com) 

Research has shown that the Skaftö wreck had probably taken on cargo in Gdansk in Poland and was heading towards Belgium when it foundered in the Lysekil archipelago around 1440. Modern methods of analysis of the cargo are now providing completely new answers about the way trade was conducted in the Middle Ages.

Central Asia identified as a key region for human ancestors      (via sciencedaily.com) 

A new study on early human migration shows that semi-arid and desert zones of Central Asia may have served as key areas for the dispersal of hominins into Eurasia during the Middle Pleistocene. Central Asia is positioned at a crossroads linking several zones important to hominin dispersal during this period, however much evidence from this region lacks context for dating and climate conditions, making it difficult to understand these dynamics.

Discovery could dramatically narrow search for space creatures      (via sciencedaily.com) 

An Earth-like planet orbiting an M dwarf -- the most common type of star in the universe -- appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets.

Looking to move to a galaxy far, far away? Innovative system evaluates habitability of distant planets      (via sciencedaily.com) 

The research framework developed, along with observational data from the Webb Space Telescope, will enable scientists to efficiently assess the atmospheres of many other planets without having to send a space crew to visit them physically. This will help us make informed decisions in the future about which planets are good candidates for human settlement and perhaps even to find life on those planets.

A 10,000-year-old infant burial provides insights into the use of baby carriers and family heirlooms in prehistory      (via sciencedaily.com) 

Researchers argue that they have found evidence of the use of baby carriers 10,000 years ago at the Arma Veirana site in Liguria, Italy.

In medieval Norway, high-class people had stronger bones      (via sciencedaily.com) 

In medieval Norway, high status individuals tended to be taller and to have stronger bones, possibly as a result of a favorable lifestyle, according to a new study.

Protecting very old trees can help mitigate climate change      (via sciencedaily.com) 

Ancient trees -- those that are many hundreds, or even thousands, of years old -- play a vital role in biodiversity and ecosystem preservation by providing stability, strength, and protection to at-risk environments. A team of ecologists highlight the importance of preserving these monumental organisms and present a project initiative to ensure their protection and longevity.

Meet the first Neanderthal family      (via sciencedaily.com) 

Researchers have managed to sequence multiple individuals from a remote Neanderthal community in Siberia. Among these thirteen individuals, the researchers identified multiple related individuals -- among these a father and his teenage daughter. The researchers were also able to use the thirteen genomes to provide a glimpse into the social organization of a Neanderthal community. They appear to have been a small group of close relatives, consisting of ten to twenty members, and communities were primarily connected through female migration.

Scientists compile Cassini's unique observations of Saturn's rings      (via sciencedaily.com) 

Scientists have compiled 41 solar occultation observations of Saturn's rings from the Cassini mission. The compilation will inform future investigations of the particle size distribution and composition of Saturn's rings, key elements to understanding their formation and evolution.

New analysis of obsidian blades reveals dynamic Neolithic social networks      (via sciencedaily.com) 

An analysis of obsidian artifacts excavated during the 1960s at two prominent archaeological sites in southwestern Iran suggests that the networks Neolithic people formed in the region as they developed agriculture are larger and more complex than previously believed. The study has applied state-of-the-art analytical tools to a collection of 2,100 obsidian artifacts.

New abiotic pathway for the formation of oxygen      (via sciencedaily.com) 

Researchers have now found evidence that double ionised sulphur dioxide contribute to the formation of oxygen molecules. This could, in particular, explain the presence of oxygen in sulphur dioxide-rich atmospheres of several of Jupiter's moons.

Reign of Papua New Guinea Highland's megafauna lasted long after humans arrived      (via sciencedaily.com) 

A giant kangaroo that once roamed on four legs through remote forests in the Papua New Guinea Highlands may have survived as recently as 20,000 years ago -- long after large-bodied megafauna on mainland Australia went extinct, new research indicates. Palaeontologists, archaeologists and geoscientists, have used new techniques to re-examine megafauna bones from the rich Nombe Rock Shelter fossil site in Chimbu Province in a bid to better understand the intriguing natural history of PNG.
