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.

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.

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.

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.

The key to developing quantum electronics may have a few kinks. According to researchers, that's not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers. The researchers fabricated a switch to turn on and off the presence of kink states, which are electrical conduction pathways at the edge of semiconducting materials.

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.

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.

Tree bark surfaces play an important role in removing methane gas from the atmosphere.

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.

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.

Two-dimensional (2D) materials have atomic-level thickness and excellent mechanical and physical properties, with broad application prospects in fields such as semiconductors, flexible devices, and composite materials.

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.

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'.

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.

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.

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.

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.

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.

Evolutionary biologists studied spoonworts to determine what influence genome duplication has on the adaptive potential of plants. The results show that polyploids -- species with more than two sets of chromosomes -- can have an accumulation of structural mutations with signals for a possible local adaptation, enabling them to occupy ecological niches time and time again.

Researchers have produced a cotton quality module -- a part of a larger forecasting tool -- allowing cotton producers to better monitor crop quality under changing environmental conditions.
