Mixed approach to reforestation better than planting or regeneration alone      (via sciencedaily.com)     Original source 

Reforestation in low- and middle-income countries can remove up to 10 times more carbon dioxide from the atmosphere at lower cost than previously estimated, making it a potentially more effective option to fight climate change. Most current reforestation programs focus on tree planting alone, but the study estimates that nearly half of all suitable reforestation locations would be more effective at sequestering carbon if forests were allowed to grow back naturally.

How well does tree planting work in climate change fight? It depends      (via sciencedaily.com)     Original source 

Using trees as a cost-effective tool against climate change is more complicated than simply planting large numbers of them, an international collaboration has shown.

Team develops safe and long-cyclable lithium metal battery for high temperatures      (via sciencedaily.com)     Original source 

In recent years, batteries have become ubiquitous in consumers' daily lives. However, existing commercial battery technologies, which use liquid electrolytes and carbonaceous anodes, have certain drawbacks such as safety concerns, limited lifespan, and inadequate power density particularly at high temperatures.

Novel electrode for improving flowless zinc-bromine battery      (via sciencedaily.com)     Original source 

The flowless zinc-bromine battery (FLZBB) is a promising alternative to flammable lithium-ion batteries due to its use of non-flammable electrolytes. However, it suffers from self-discharge due to the crossover of active materials, generated at the positive graphite felt (GF) electrode, to the negative electrode, significantly affecting performance. Now, researchers have developed a novel nitrogen-doped mesoporous carbon-coated GF electrode that effectively suppresses self-discharge. This breakthrough can lead to practical applications of FLZBB in energy storage systems.

Discovery of a hybrid lineage offers clues to how trees adapt to climate change      (via sciencedaily.com)     Original source 

The discovery of a hybrid population of poplar trees in western Wyoming has provided insight into how natural hybridization informs the evolution of many plant species, according to researchers. They also said their discovery suggests that genetic exchange between species may be critical for adaptation to environmental change.

Completely stretchy lithium-ion battery for flexible electronics      (via sciencedaily.com)     Original source 

When you think of a battery, you probably don't think stretchy. But batteries will need this shape-shifting quality to be incorporated into flexible electronics, which are gaining traction for wearable health monitors. Now, researchers report a lithium-ion battery with entirely stretchable components, including an electrolyte layer that can expand by 5000%, and it retains its charge storage capacity after nearly 70 charge/discharge cycles.

Forests endure as carbon sink despite regional pressures      (via sciencedaily.com)     Original source 

Despite facing regional threats like deforestation and wildfires, the world's forests continue to be a powerful weapon in the fight against climate change. A new study reveals these vital ecosystems have consistently absorbed carbon dioxide for the past three decades, even as disruptions chip away at their capacity. The study, based on long-term ground measurements combined with remote sensing data, found that forests take up an average of 3.5 0.4 billion metric tons of carbon per year, which is nearly half of the carbon dioxide emissions from burning fossil fuels between 1990 and 2019.

Logged forests can still have ecological value -- if not pushed too far      (via sciencedaily.com)     Original source 

Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.

Scientists use machine learning to predict diversity of tree species in forests      (via sciencedaily.com)     Original source 

Researchers used machine learning to generate highly detailed maps of over 100 million individual trees from 24 sites across the U.S. These maps provide information about individual tree species and conditions, which can greatly aid conservation efforts and other ecological projects.

Making rechargeable batteries more sustainable with fully recyclable components      (via sciencedaily.com)     Original source 

Rechargeable solid-state lithium batteries are an emerging technology that could someday power cell phones and laptops for days with a single charge. Offering significantly enhanced energy density, they are a safer alternative to the flammable lithium-ion batteries currently used in consumer electronics -- but they are not environmentally friendly. Current recycling methods focus on the limited recovery of metals contained within the cathodes, while everything else goes to waste.

Study examines urban forests across the United States      (via sciencedaily.com)     Original source 

Tree-planting campaigns have been underway in the United States, especially in cities, as part of climate mitigation efforts given the many environmental benefits of urban forests. But a new study finds that some areas within urban forests in the U.S., may be more capable than trees growing around city home lawns in adapting to a warmer climate.

BESSY II shows how solid-state batteries degrade      (via sciencedaily.com)     Original source 

Solid-state batteries have several advantages: they can store more energy and are safer than batteries with liquid electrolytes. However, they do not last as long and their capacity decreases with each charge cycle. But it doesn't have to stay that way: Researchers are already on the trail of the causes.
