Two epicenters led to Japan's violent Noto earthquake on New Year's Day      (via sciencedaily.com)     Original source 

The 7.5- magnitude earthquake beneath Japan's Noto Peninsula on Jan. 1, 2024, occurred when a 'dual-initiation mechanism' applied enough energy from two different locations to break through a fault barrier -- an area that locks two sides of a fault in place and absorbs the energy of fault movement, slowing it down or stopping it altogether.

Creature the size of a dust grain found hiding in California's Mono Lake      (via sciencedaily.com)     Original source 

Mono Lake is a beautiful but harsh environment, its salty and arsenic-laced water home to brine shrimp, alkali flies and little else. Scientists recently discovered an unsuspected resident, however, a microscopic creature -- a choanoflagelatte -- that forms colonies that harbor their own unique bacterial microbiomes. The creature, part of the sister group to all animals, could shed light on the evolution of animals' intimate interactions with bacteria and the rise of multicellular life.

Fighting coastal erosion with electricity      (via sciencedaily.com)     Original source 

New research has systematically demonstrated that a mild zap of electricity can strengthen a marine coastline for generations -- greatly reducing the threat of erosion in the face of climate change and rising sea levels. The new process forms natural cement between grains of sand, transforming it into solid, immoveable rock. Mollusks use a similar process to turn naturally occurring minerals into shells.

Chalk-based coating creates a cooling fabric      (via sciencedaily.com)     Original source 

In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.

Pilot study uses recycled glass to grow plants for salsa ingredients      (via sciencedaily.com)     Original source 

Tortilla chips and fresh salsa are tasty, but they could be even more appealing if you grow the ingredients yourself. Now, researchers report that some salsa ingredients -- cilantro, bell pepper and jalapeno -- can be more sustainably cultivated with recycled glass. Their pilot study found that partially substituting soil in a planter with recycled glass fragments speeds up plant development and reduces unwanted fungal growth.

Development of a model capable of predicting the cycle lives of high-energy-density lithium-metal batteries      (via sciencedaily.com)     Original source 

Scientists have developed a model capable of predicting the cycle lives of high-energy-density lithium-metal batteries by applying machine learning methods to battery performance data. The model proved able to accurately estimate batteries' longevity by analyzing their charge, discharge and voltage relaxation process data without relying on any assumption about specific battery degradation mechanisms. The technique is expected to be useful in improving the safety and reliability of devices powered by lithium-metal batteries.

Hailstone library to improve extreme weather forecasting      (via sciencedaily.com)     Original source 

Researchers are measuring and scanning samples for a global 'hailstone library'. Storm simulations using 3-D modelling of real hailstones -- in all sorts of weird shapes from oblong to flat discs or with spikes coming out -- show it behaves differently than spherical hail shapes. Data from the hail library could lead to more accurate storm forecasts.
