Published Climate change will bring more turbulence to flights in the Northern Hemisphere, study finds
(via sciencedaily.com) Original source A type of invisible, unpredictable air turbulence is expected to occur more frequently in the Northern Hemisphere as the climate warms. Known as clear air turbulence, the phenomenon also increased in the Northern Hemisphere between 1980 and 2021.
Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine
(via sciencedaily.com) Original source Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published The ocean is becoming too loud for oysters, research finds
(via sciencedaily.com) Original source Baby oysters rely on natural acoustic cues to settle in specific environments, but new research reveals that noise from human activity is interfering with this critical process.
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 Whale shark tracked for record-breaking four years
(via sciencedaily.com) Original source Researchers have been tracking a 26-foot endangered whale shark -- named 'Rio Lady' -- with a satellite transmitter for more than four years -- a record for whale sharks and one of the longest tracking endeavors for any species of shark.
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 Eyes for Love: Searching for light and a mate in the deep, dark sea, male dragonfishes grow larger eyes than the females they seek
(via sciencedaily.com) Original source The eyes of the male dragonfish grow larger for mate seeking, a sexual dimorphism that makes the dragonfish an anomaly in vertebrate evolution, researchers report.
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 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.
Published Reef pest feasts on 'sea sawdust'
(via sciencedaily.com) Original source Researchers have uncovered an under the sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as 'sea sawdust'.
Published 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.
Published Smart soil can water and feed itself
(via sciencedaily.com) Original source A newly engineered type of soil can capture water out of thin air to keep plants hydrated and manage controlled release of fertilizer for a constant supply of nutrients.
Published 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.
Published Weather experts discover new effect of storm -- in a teacup
(via sciencedaily.com) Original source A new study reveals that Storm Ciaran cut an invisible path of mayhem across southern Britain last autumn, destroying any possibility that 20 million people could have a proper cup of tea at breakfast. The storm's record-breaking low pressure meant the boiling point of water was below the crucial 100 degrees Celsius required for a decent cuppa.
Published History shows that humans are good for biodiversity... sometimes
(via sciencedaily.com) Original source Humans have been an important driver of vegetation change over thousands of years, and, in some places, had positive impacts on biodiversity, according to a new study.
Published Building a roadmap to bioengineer plants that produce their own nitrogen fertilizer
(via sciencedaily.com) Original source Nitrogen fertilizers make it possible to feed the world's growing population, but they are also costly adn harm ecosystems. However, a few plants have evolved the ability to acquire their own nitrogen with the help of bacteria, and a new study helps explain how they did it, not once, but multiple times.
Published 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.
Published Scientists create computer program that 'paints' the structure of molecules in the style of Piet Mondrian
(via sciencedaily.com) Original source Scientists have created a computer program that 'paints' the structure of molecules in the style of famous Dutch artist, Piet Mondrian. Researchers are opening eyes and minds to the beauty of molecular structure, as well as posing new questions about the form and function of the molecules themselves.
