Seasonal fog alleviates drought stress of rubber trees in Xishuangbanna
The importance of fog in forest ecosystems has been recognized and debated for centuries. However, the extent to which the leaves of rubber plants can maintain net CO2 assimilation in the fog season is not known......»»
Record-breaking drought in southern China linked to Eurasian warming and tropical sea surface temperature
Southern China experienced an extreme drought that persisted from summer to autumn in 2022, ranking as the most severe drought since 1980. The reason for the occurrence of this extreme drought event was investigated. It shows that both the Eurasian w.....»»
Model highlights three roots of online toxicity
In 2022, Professor of Cognitive Neuroscience Dean Mobbs began to investigate the relationship between social media use and mental health and well-being. As his research program ramps up to test brain activity and physiological markers of stress durin.....»»
From antiquity to adaptation: Tracing the genetic journey of east Asian chestnut varieties
Uncovering the genetic saga of Castanea trees, a study maps their evolutionary journey and local climate adaptations. This research reveals the genetic markers and molecular mechanisms that have allowed these nut fruit trees to adapt and flourish acr.....»»
How engineered walnuts combat drought through grafting
Drought is a major threat to walnut production globally, often resulting in lower yields and weaker trees. While grafting has traditionally been used to improve the resilience of fruit and nut trees, the exact mechanisms of signal transfer between ro.....»»
Satellites reveal ecosystems most vulnerable to drought
More severe droughts that will also last longer: this will primarily be a problem for irrigated croplands, as discovered by environmental scientist Qi Chen. Mixed forests with a variety of plant species will be the least vulnerable. Chen compared the.....»»
Researchers identify effective materials for protecting astronauts from harmful cosmic radiation on Mars
Researchers have identified specific materials, including certain plastics, rubber, and synthetic fibers, as well as Martian soil (regolith), which would effectively protect astronauts by blocking harmful space radiation on Mars. These findings could.....»»
Ecosystems study finds the higher the environmental stress, the lower the resistance to global change
An international study led by the Institute of Natural Resources and Agrobiology of Seville (IRNAS-CSIC), of the Spanish National Research Council (CISC), has shown that as the number of global change factors increases, terrestrial ecosystems become.....»»
Carbon emissions from forest soil will likely grow with rising temperatures
The soils of northern forests are key reservoirs that help keep the carbon dioxide that trees inhale and use for photosynthesis from making it back into the atmosphere. But a unique experiment led by Peter Reich of the University of Michigan is showi.....»»
Research team designs AI approach to drought zoning in Canada
A recent study by the University of Ottawa and Laval University shows that climate change may cause many areas in Canada to experience significant droughts by the end of the century. In response, the researchers have introduced an advanced AI-based m.....»»
Honey bees may play key role in spreading viruses to wild bumble bees
Honey bees may play a role in increasing virus levels in wild bumble bees each spring, according to researchers at Penn State who analyzed seasonal trends of parasite and virus transmission in bees......»»
Advances in bermudagrass research highlight genetic insights, potential for environmental resilience
A research team has reviewed recent studies to highlight the significant progress in understanding the growth and stress response mechanisms in bermudagrass, a widely distributed and valuable grass species. A recent review reveals the genetic diversi.....»»
Amazonian drought may have long-lasting effects on carbon cycle
The 2015–2016 El Niño hit the Amazon basin hard, causing a drought that severely reduced aboveground vegetation and caused the basin to release nearly 1 gigaton of carbon into the atmosphere......»»
Trees stripped by invasive caterpillars muster defenses that can harm native insects, research shows
An invasive insect with an insatiable appetite can cause serious problems for a favorite native moth that likes the same food source—even though the two are never in direct competition for a meal, according to new research, published in the journal.....»»
Going slow is better for fast cycling: Study reveals unique replication fork behavior in pluripotent stem cells
Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic replication stress. However, a recent report published in E.....»»
The pioneering sugarcane variety transforming China"s sugar industry
A research team at the Liucheng Sugarcane Research Units (LC-SRU) developed the fifth-generation sugarcane variety LC05-136, which has become a flagship in China due to its high yield, high sugar content, and strong tolerance to drought and cold stre.....»»
New insights on how bird flu crosses the species barrier
In recent years, public health measures, surveillance, and vaccination have helped bring about significant progress in reducing the impact of seasonal flu epidemics, caused by human influenza viruses A and B. However, a possible outbreak of avian inf.....»»
Teenagers" motivation dips in high school—research shows supportive teachers can really help
Adolescence is often characterized as a time of "storm and stress"......»»
New research shows agricultural impacts on soil microbiome and fungal communities
New research from Smithsonian's Bird Friendly Coffee program highlights a type of biodiversity that often gets overlooked: soil bacteria and fungal communities. For over twenty years, Smithsonian research has shown that coffee farms with shade trees.....»»
New analytical tools identify distinct components of dissolved organic matter within the ocean water column
Large quantities of carbon are stored across the environment as naturally-occurring dissolved organic matter. In the ocean, this organic carbon has an average age of thousands of years, but seasonal fluctuations in dissolved organic matter concentrat.....»»
Trees compete for space, light and resources, and those clashes can leave battle scars
When you walk through a forest, it may feel like a static setting where very little is happening. But trees are constantly interacting and reacting to each other as they grow. There's intense competition for light and space. Every shift affects the o.....»»
