Published Plants offer fruit to insects to disperse dust-like seeds
(via sciencedaily.com) Original source Fruit exist to invite animals to disperse the swallowed seeds. A research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like seeds and fruit suitable for the minute, ground-dwelling animals.
Published Study analyzes potato-pathogen 'arms race' after Irish famine
(via sciencedaily.com) Original source Researchers reveal more about the tit-for-tat evolutionary changes occurring in both potato plants and the pathogen that caused the 1840s Irish potato famine.
Published Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species
(via sciencedaily.com) Original source A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.
Published Warming stops tiny organisms working together
(via sciencedaily.com) Original source Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows.
Published Scientists discover entirely new wood type that could be highly efficient at carbon storage
(via sciencedaily.com) Original source Researchers undertaking an evolutionary survey of the microscopic structure of wood from some of the world's most iconic trees and shrubs have discovered an entirely new type of wood.
Published From genes to jeans: New genetic insights may lead to drought resilient cotton
(via sciencedaily.com) Original source Cotton is woven into the very fabric of our lives, from soft T-shirts to comfortable jeans and cozy bedsheets. It's the world's leading renewable textile fiber and the backbone of a global industry worth billions. As climate change intensifies, cotton farmers face increasing challenges from drought and heat. However, new research offers hope for developing more resilient varieties that can maintain high yields even under water-stressed conditions.
Published Scientists untangle interactions between the Earth's early life forms and the environment over 500 million years
(via sciencedaily.com) Original source The atmosphere, the ocean and life on Earth interacted over the past 500-plus million years in ways that improved conditions for early organisms to thrive. Now, an interdisciplinary team of scientists has produced a perspective article of this co-evolutionary history.
Published Faster, cleaner way to extract lithium from battery waste
(via sciencedaily.com) Original source Researchers uncover a rapid, efficient and environmentally friendly method for selective lithium recovery using microwave radiation and a readily biodegradable solvent.
Published Scientists work to build 'wind-up' sensors
(via sciencedaily.com) Original source An international team of scientists has shown that twisted carbon nanotubes can store three times more energy per unit mass than advanced lithium-ion batteries. The finding may advance carbon nanotubes as a promising solution for storing energy in devices that need to be lightweight, compact, and safe, such as medical implants and sensors.
Published Climate is most important factor in where mammals choose to live, study finds
(via sciencedaily.com) Original source Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live.
Published New battery-free technology to power electronic devices using ambient radiofrequency signals
(via sciencedaily.com) Original source Researchers demonstrated a novel technique to efficiently convert ambient low-power radiofrequency signals into DC power. This 'rectifier' technology can be easily integrated into energy harvesting modules to power electronic devices and sensors, enabling battery-free operation.
Published Researchers develop innovative battery recycling method
(via sciencedaily.com) Original source A research team is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.
Published 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.
Published 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.
Published Trees reveal climate surprise -- bark removes methane from the atmosphere
(via sciencedaily.com) Original source Tree bark surfaces play an important role in removing methane gas from the atmosphere.
Published Biosensor reveals gibberellin's critical role in legume nitrogen-fixation -- paving the way for self-fertilizing cereals
(via sciencedaily.com) Original source Researchers demonstrate that the plant hormone gibberellin (GA) is essential for the formation and maturation of nitrogen-fixing root nodules in legumes and can also increase nodule size.
Published Heat-sensitive trees move uphill seeking climate change respite
(via sciencedaily.com) Original source Trees in the Brazilian Atlantic Forest are migrating in search of more favourable temperatures with species in mountain forests moving uphill to escape rising heat caused by climate change.
Published 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.
Published 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.
Published Groundcherry gets genetic upgrades: Turning a garden curiosity into an agricultural powerhouse
(via sciencedaily.com) Original source Imagine a small fruit that tastes like a cross between a tomato and a pineapple, wrapped in its own natural paper lantern. That's the groundcherry (Physalis grisea) -- a little-known relative of tomatoes that's been quietly growing in gardens and small farms across North America for centuries. Now, this humble fruit is getting a 21st-century upgrade thanks to some cutting-edge genetic research.
