Researchers discover smarter way to recycle polyurethane      (via sciencedaily.com)     Original source 

Researchers have found a better method to recycle polyurethane foam from items like mattresses: They are not only able to break down PUR and separate the two main components -- they can do it in one go. This is great news for the budding industry that aims to chemically recover the original components of the material -- making their products cheaper and better.

Why isn't Colorado's snowpack ending up in the Colorado River? New research suggests the problem might be the lack of spring rainfall      (via sciencedaily.com)     Original source 

The Colorado River and its tributaries provide water for hydropower, irrigation and drinking water in seven U.S. states and Mexico. But since 2000, water managers have struggled to predict how much water will come from the snowpack. The problem lies with the lack of rainfall in the spring, according to new research.

U.S. capable of achieving seafood independence      (via sciencedaily.com)     Original source 

If the U.S. became seafood independent, or meet its entire seafood needs through its own production, it could offer opportunities for improving dietary outcomes as well as individual and national food security, particularly against disruptions in global supply chains. Through analyzing 50 years of regional and national consumption and production data, from 1970-2021, researchers found that the U.S. could achieve seafood independence, although 'achieving greater seafood independence would require shifts in consumer behavior, investments in infrastructure and continual adaptation in the face of climate change.'

Intelligent soft robotic clothing for automatic thermal adaptation in extreme heat      (via sciencedaily.com)     Original source 

As global warming intensifies, people increasingly suffer from extreme heat. For those working in a high-temperature environment indoors or outdoors, keeping thermally comfortable becomes particularly crucial. A team has now developed thermally-insulated and breathable soft robotic clothing that can automatically adapt to changing ambient temperatures, thereby helping to ensure worker safety in hot environments.

Rising mercury pollution in soil could be related to climate change      (via sciencedaily.com)     Original source 

In 2017, the Minamata Convention on Mercury went into effect, designed to help curb mercury emissions and limit exposure across the globe. However, a new study of mercury levels in soil suggests that the treaty's provisions might not be enough. The study estimates that soil stores substantially more mercury than previously thought, and it predicts that increases in plant growth due to climate change may add even more.

Rocks collected on Mars hold key to water and perhaps life on the planet: Bring them back to Earth      (via sciencedaily.com)     Original source 

Between July and November of 2022, NASA's Perseverance rover collected seven samples of sediment from an ancient alluvial fan in Jezero crater. While onboard analysis gave researchers some information about their origins, only detailed analysis on Earth can retrieve evidence of when water flowed on Mars and whether life arose there. Geophysicists had hoped to get these samples back by 2033, but NASA's sample return mission may be delayed beyond that date.

Newly discovered ability of comammox bacteria could help reduce nitrous oxide emissions in agriculture      (via sciencedaily.com)     Original source 

An international research team has discovered that comammox bacteria, first identified by them in 2015, can grow using guanidine, a nitrogen-rich organic compound, as their sole energy and nitrogen source. This unique ability opens new avenues for targeted cultivation of these enigmatic microbes and could also provide a key to reducing agricultural nitrous oxide emissions.
