Stalactites and stalagmites in the battery?      (via sciencedaily.com) 

They are considered the 'Holy Grail' of battery research: so-called 'solid-state batteries'. They no longer have a liquid core, as is the case with today's batteries, but consist of a solid material. This leads to several advantages: Among other things, these batteries are more difficult to ignite and can also be manufactured on a miniature scale. Scientists have now turned their attention to the life cycle of such batteries and targeted processes that reduce it. With their findings, more durable solid-state batteries could be realized in the future.

East Coast, US, landslide impacts from Puerto Rico to Vermont and in between      (via sciencedaily.com) 

In the U.S., we may often think of landslides as primarily a West Coast problem, mostly plaguing the mountainous terrain of California, Oregon, and Washington. New research highlights the major impacts of landslides on the U.S. East Coast and what is being done to save lives and deal with the damages.

High winds can worsen pathogen spread at outdoor chicken farms      (via sciencedaily.com) 

A study of chicken farms in the West found that high winds increased the prevalence of Campylobacter in outdoor flocks, a bacterial pathogen in poultry that is the largest single cause of foodborne illness in the U.S. Researchers found that about 26% of individual chickens had the pathogen at the 'open environment' farms in the study, which included organic and free-range chicken farms. High winds the week prior to sampling and the farms' location in more intensive agricultural settings were linked to a greater prevalence of Campylobacter.

A mechanistic and probabilistic method for predicting wildfires      (via sciencedaily.com) 

In the event of dry weather and high winds, power system-ignited incidents are more likely to develop into wildfires. The risk is greater if vegetation is nearby. A new study provides the methodology for predicting at what point during a high wind storm, powerline ignition is likely.

Entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms      (via sciencedaily.com) 

The arrival of the new year is a prime time for Antarctic birds like the south polar skua, Antarctic petrel, and snow petrel to build nests and lay their eggs. However, from December 2021 to January 2022, researchers did not find a single skua nest on Svarthamaren, one of the regions where the birds go to raise their young. Similarly, the number of Antarctic petrel and snow petrel nests dropped to almost zero.

The world's atmospheric rivers now have an intensity ranking like hurricanes      (via sciencedaily.com) 

Atmospheric rivers, which are long, narrow bands of water vapor, are becoming more intense and frequent with climate change. A new study demonstrates that a recently developed scale for atmospheric river intensity (akin to the hurricane scale) can be used to rank atmospheric rivers and identify hotspots of the most intense atmospheric rivers not only along the U.S. West Coast but also worldwide.

Underused satellite, radar data may improve thunderstorm forecasts      (via sciencedaily.com) 

Tens of thousands of thunderstorms may rumble around the world each day, but accurately predicting the time and location where they will form remains a grand challenge of computer weather modeling. A new technique combining underused satellite and radar data in weather models may improve these predictions, according to a team of scientists.

Controlling electric double layer dynamics for next generation all-solid-state batteries      (via sciencedaily.com) 

Development of all-solid-state batteries is crucial to achieve carbon neutrality. However, their high surface resistance causes these batteries to have low output, limiting their applications. To this end, researchers have employed a novel technique to investigate and modulate electric double layer dynamics at the solid/solid electrolyte interface. The researchers demonstrate unprecedented control of response speed by over two orders of magnitude, a major steppingstone towards realization of commercial all-solid-state batteries.

Extreme fast charging capability in lithium-ion batteries      (via sciencedaily.com) 

Lithium-ion batteries dominate among energy storage devices and are the battery of choice for the electric vehicle industry. Improving battery performance is a constant impetus to current research in this field. Towards this end, a group of researchers has synthesized a lithium borate-type aqueous polyelectrolyte binder for graphite anodes. Their new binder helped improve Li-ion diffusion and lower impedance compared to conventional batteries.

Seabirds in the eye of the storm      (via sciencedaily.com) 

Hurricanes are becoming more intense due to the climate crisis. Therefore, researchers have studied the wind speeds that different seabird species can withstand. The team was able to show that the individual species are well adapted to the average wind conditions in their breeding grounds, but use different strategies to avoid flying through the storm. Within their research, one behavior of the albatrosses particularly surprised the scientists.

How to predict city traffic      (via sciencedaily.com) 

A new machine learning model can predict traffic activity in different zones of cities. To do so, a researcher used data from a main car-sharing company in Italy as a proxy for overall city traffic. Understanding how different urban zones interact can help avoid traffic jams, for example, and enable targeted responses of policy makers -- such as local expansion of public transportation.

One is bad enough: climate change raises the threat of back-to-back hurricanes      (via sciencedaily.com) 

Driven by a combination of rising sea levels and climate change, destructive hurricanes and tropical storms could become far more likely to hit coastal areas in quick succession, researchers found. In some areas such double hits could occur as frequently as once every 3 years.

Why do Earth's hemispheres look equally bright when viewed from space?      (via sciencedaily.com) 

When seen from space, Earth's hemispheres -- northern and southern -- appear equally bright. For years, the brightness symmetry between hemispheres remained a mystery. In a new study, researchers reveal a strong correlation between storm intensity, cloudiness and the solar energy reflection rate in each hemisphere. They offer a solution to the mystery, alongside an assessment of how climate change might alter the reflection rate in the future.
