Batteries without critical raw materials      (via sciencedaily.com) 

The market for rechargeable batteries is growing rapidly, but the necessary raw materials are limited. Sodium-ion batteries, for example, could offer an alternative. Researchers have investigated new combinations of electrolyte solutions and electrode materials for this purpose.

Researchers design next-generation electrolytes for lithium metal batteries      (via sciencedaily.com) 

A team of researchers has discovered a new mechanism to stabilize the lithium metal electrode and electrolyte in lithium metal batteries. This new mechanism, which does not depend on the traditional kinetic approach, has potential to greatly enhance the energy density of batteries.

Limits of lithium extraction from thermal water      (via sciencedaily.com) 

Pumping up thermal water, separating lithium, and using it to produce batteries for electric mobility -- the idea of lithium as an environmentally compatible and regionally available by-product of geothermal energy plants appears highly promising. However, it has not been clear so far whether domestic lithium extraction is really worthwhile. A team of researchers has now summarized the state of the art, analyzed raw materials markets, and assessed technologies.

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.

Keeping electricity affordable on wireless charging highways      (via sciencedaily.com) 

Efficient pricing will be crucial to minimize energy costs for private operators who provide on-the-highway wireless charging for electric cars -- and for consumers who will use this service, according to new research.

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.

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.

Chemists boost eco-friendly battery performance using catalysts with unconventional phase nanostructures      (via sciencedaily.com) 

The metal-carbon dioxide battery is a promising and environmentally friendly technology, but its energy efficiency is limited. Recently, a research team has discovered an innovative way to overcome this problem by introducing an unconventional phase nanomaterial as a catalyst, boosting battery energy efficiency up to 83.8%. The study reveals a novel design of catalysts for the new generation of meta-gas batteries that can contribute to carbon neutral goals.

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.

Shrine discovered with rituals never seen to take place before in an Egyptian temple      (via sciencedaily.com)     Original source 

Researchers recently published new findings from the excavations of the Berenike site, a Greco-Roman seaport in the Egyptian Eastern desert. The study results describes the excavation of a religious complex from the Late Roman Period (between the fourth and sixth centuries) with unprecedented discoveries linked to the presence of the Blemmyes, a nomadic people. Fifteen falcons, many of them headless and buried around a pedestal, point to a ritual performed by the Blemmyes people to their falcon god. The shrine, located at the Hellenistic-Roman seaport of Berenike, contains a curious inscription prohibiting the boiling of animal heads inside the shrine.

Geneticists discover new wild goat subspecies via ancient DNA      (via sciencedaily.com) 

Geneticists have discovered a previously unknown lineage of wild goats over ten millennia old. The new goat type, discovered from genetic screening of bone remains and referred to as 'the Taurasian tur', likely survived the Last Glacial Maximum (the ice age), which stranded their ancestors in the high peaks of the Taurus Mountains in Turkey where their remains were found.
