Scientists have conducted a detailed examination of high-nickel-content layered cathodes, considered to be components of promise in next-generation lithium-ion batteries. Advanced electron microscopy and deep machine learning enabled the team to observe atomic-scale changes at the interface of materials that make up the batteries.

A new study finds that microorganisms live in richly diverse and interdependent communities in high-temperature geothermal environments in the deep sea. By constructing genomes of 3,635 Bacteria and Archaea from 40 different rock communities, researchers discovered at least 500 new genera and have evidence for two new phyla. Samples from the deep-sea Brothers volcano were especially enriched with different kinds of microorganisms, many endemic to the volcano. The genomic data from this study also showed that many of these organisms depend on one another for survival. Some microorganisms cannot metabolize all of the nutrients they need to survive so they rely on nutrients created by other species in a process known as a 'metabolic handoff.'

New research into the durability and age of an ancient asteroid made of rocky rubble and dust, revealed significant findings that could contribute to potentially saving the planet if one ever hurtled toward Earth.

On the short-lived island of Hunga Tonga Hunga Ha'apai, researchers discovered a unique microbial community that metabolizes sulfur and atmospheric gases, similar to organisms found in deep sea vents or hot springs.

New findings begin to fill major gaps in understanding about how geological faults behave and appear as they deepen, and they could eventually help lead future researchers to develop better earthquake models on strike-slip faults, regions with frequent and major earthquakes.

Flow batteries offer a solution. Electrolytes flow through electrochemical cells from storage tanks in this rechargeable battery. The existing flow battery technologies cost more than $200/kilowatt hour and are too expensive for practical application, but engineers have now developed a more compact flow battery cell configuration that reduces the size of the cell by 75%, and correspondingly reduces the size and cost of the entire flow battery. The work could revolutionize how everything from major commercial buildings to residential homes are powered.

Translating electrochemical performance of large format batteries to microscale power sources has been a long-standing technological challenge, limiting the ability of batteries to power microdevices, microrobots and implantable medical devices. Researchers have created a high-voltage microbattery (> 9 V), with high-energy and -power density, unparalleled by any existing battery design.

An international team of collaborators have revealed the most detailed look yet at the planet's recent climactic history, including summer and winter temperatures dating back 11,000 years to the beginning of what is known as the Holocene.

A researcher has developed technology that could prevent electric vehicle fires, like those caused by saltwater flooding from Hurricane Ian. The technology, an aqueous battery, replaces the volatile and highly flammable organic solvents found in electric vehicle lithium-ion batteries with saltwater to create a battery that is safer, faster charging, just as powerful and won't short circuit during flooding.

A research team has built and tested a new interlayer to prevent dissolution of the sulfur cathode in lithium-sulfur batteries. This new interlayer increases Li-S cell capacity and maintains it over hundreds of cycles.

Lithium is expensive and limited, necessitating the development of efficient energy storage systems beyond lithium-ion batteries. Sodium is a promising candidate. However, sodium ions, being large and sluggish, hamper sodium-ion battery (SIB) anode performance. Researchers have recently developed pyrolyzed quinacridones, new carbonaceous SIB anode materials, that are efficient, easily prepared, and exhibit excellent electrochemical properties, including high sodium-ion storage performance and cycling stability.

Researchers have created a map of oceanic 'dead zones' that existed during the Pliocene epoch, when the Earth's climate was two to three degrees warmer than it is now. The work could provide a glimpse into the locations and potential impacts of future low oxygen zones in a warmer Earth's oceans.

A new study that reconstructs the history of sea level at the Bering Strait shows that the Bering Land Bridge connecting Asia to North America did not emerge until around 35,700 years ago, less than 10,000 years before the height of the last ice age (known as the Last Glacial Maximum). The findings indicate that the growth of the ice sheets -- and the resulting drop in sea level -- occurred surprisingly quickly and much later in the glacial cycle than previous studies had suggested.
