Interdisciplinary environmental history: How narratives of the past can meet the challenges of the anthropocene      (via sciencedaily.com) 

A new article discusses vital methodological issues for humanities-based historical inquiry and argues that the challenges of the Anthropocene demand interdisciplinary research informed by a variety of historical narratives.

Nanoengineers develop a predictive database for materials      (via sciencedaily.com) 

Nanoengineers have developed an AI algorithm that predicts the structure and dynamic properties of any material -- whether existing or new -- almost instantaneously. Known as M3GNet, the algorithm was used to develop matterverse.ai, a database of more than 31 million yet-to-be-synthesized materials with properties predicted by machine learning algorithms. Matterverse.ai facilitates the discovery of new technological materials with exceptional properties.

One of Europe's most ancient domestic dogs lived in the Basque Country      (via sciencedaily.com) 

Wolf domestication occurred earlier than proposed until now, at least in western Europe. That possibility is raised by the results of the study of the humerus found in the Erralla cave (Gipuzkoa, Spain) in 1985.

Scientists convert waste paper into battery parts for smartphones and electric vehicles      (via sciencedaily.com) 

Scientists have developed a technique to convert waste paper, from single-use packaging and bags, and cardboard boxes, into a crucial component of lithium-ion batteries. Through a process called carbonisation which converts paper into pure carbon, the researchers turned the paper's fibers into electrodes, which can be made into rechargeable batteries that power mobile phones, medical equipment, and electric vehicles.

1,700-year-old spider monkey remains discovered in Teotihuacán, Mexico      (via sciencedaily.com)     Original source 

The complete skeletal remains of a spider monkey -- seen as an exotic curiosity in pre-Hispanic Mexico -- grants researchers new evidence regarding social-political ties between two ancient powerhouses: Teotihuacán and Maya Indigenous rulers. The remains of other animals were also discovered, as well as thousands of Maya-style mural fragments and over 14,000 ceramic sherds from a grand feast. These pieces are more than 1,700 years old.

Engineers solve a mystery on the path to smaller, lighter batteries      (via sciencedaily.com) 

A new discovery could finally usher the development of solid-state lithium batteries, which would be more lightweight, compact, and safe than current lithium batteries. The growth of metallic filaments called dendrites within the solid electrolyte has been a longstanding obstacle, but the new study explains how dendrites form and how to divert them.

Footprints claimed as evidence of ice age humans in North America need better dating, new research shows      (via sciencedaily.com) 

The preserved footprints found in New Mexico's Lake Otero Basin would upend scientific understanding of how, and when, humans first arrived in North America, if they are accurately dated. A new study brings the age claim into question.

Putting the brakes on lithium-ion batteries to prevent fires      (via sciencedaily.com) 

Lithium-ion (Li-ion) batteries are used to power everything from smart watches to electric vehicles, thanks to the large amounts of energy they can store in small spaces. When overheated, however, they're prone to catching fire or even exploding. But recent research offers a possible solution with a new technology that can swiftly put the brakes on a Li-ion battery, shutting it down when it gets too hot.

Previously unknown monumental temple discovered near the Tempio Grande in Vulci      (via sciencedaily.com) 

Archeologists have identified one of the largest known sacred buildings of the Etruscans. The temple's strata offer insights into more than 1000 years of development of one of the most important Etruscan cities. The newly discovered temple is roughly the same size and on a similar alignment as the neighboring Tempio Grande, and was built at roughly the same Archaic time. This duplication of monumental buildings in an Etruscan city is rare, and indicates an exceptional finding.

Old bone links lost American parrot to ancient Indigenous bird trade      (via sciencedaily.com) 

For centuries, Indigenous communities in the American Southwest imported colorful parrots from Mexico. But according to a recent study, some parrots may have been captured locally and not brought from afar. The research challenges the assumption that all parrot remains found in American Southwest archaeological sites have their origins in Mexico. It also presents an important reminder: The ecology of the past can be very different from what we see today.

Human expansion 1,000 years ago linked to Madagascar's loss of large vertebrates      (via sciencedaily.com) 

The island of Madagascar -- one of the last large land masses colonized by humans - -sits about 250 miles (400 kilometers) off the coast of East Africa. While it's still regarded as a place of unique biodiversity, Madagascar long ago lost all its large-bodied vertebrates, including giant lemurs, elephant birds, turtles, and hippopotami. A human genetic study now links these losses in time with the first major expansion of humans on the island, around 1,000 years ago.

Ancient DNA analysis sheds light on the early peopling of South America      (via sciencedaily.com) 

Using DNA from two ancient humans unearthed in two different archaeological sites in northeast Brazil, researchers have unraveled the deep demographic history of South America at the regional level with some surprising results. Not only do they provide new genetic evidence supporting existing archaeological data of the north-to-south migration toward South America, they also have discovered migrations in the opposite direction along the Atlantic coast -- for the first time. Among the key findings, they also have discovered evidence of Neanderthal ancestry within the genomes of ancient individuals from South America.
