Published 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.
Published 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.
Published Human evolution wasn't just the sheet music, but how it was played
(via sciencedaily.com) A team of researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.
Published 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.
Published 'Primordial super-enhancers' provide early snapshot of the mechanisms that allowed for multicellularity
(via sciencedaily.com) A new study has found that organelle-like transcriptional condensates are an ancient and flexible tool used by cells to drive rapid gene expression.
Published 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.
Published 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.
Published Understanding a cerium quirk could help advance grid-scale energy storage
(via sciencedaily.com) An explanation for why flow batteries using the metal cerium in a sulfuric acid electrolyte fall short on voltage could pave the way for better battery chemistry.
Published Oldest evidence of the controlled use of fire to cook food, researchers report
(via sciencedaily.com) Original source The remains of a huge carp fish mark the earliest signs of cooking by prehistoric human to 780,000 years ago, predating the available data by some 600,000 years, according to researchers.
Published 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.
Published Previously unseen processes reveal path to better rechargeable battery performance
(via sciencedaily.com) To design better rechargeable ion batteries, engineers and chemists have collaborated to combine a powerful new electron microscopy technique and data mining to visually pinpoint areas of chemical and physical alteration within ion batteries.
Published Water for drinking? Nope, water for batteries
(via sciencedaily.com) A research team develops aqueous rechargeable batteries based on zinc anodes. Polymeric artificial interphase to improve battery stability.
Published 2D nanosheets as anodes in Li-ion batteries: The answer is in the sheets
(via sciencedaily.com) Researchers use titanium diboride nanosheets as anode material in lithium-ion batteries to enable fast charging and extend battery life.
Published 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.
Published 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.
Published 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.
Published 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.
Published Watching lithium in real time could improve performance of EV battery materials
(via sciencedaily.com) Researchers have found that the irregular movement of lithium ions in next-generation battery materials could be reducing their capacity and hindering their performance.
