Winter precipitation and temperature constrain distribution of cedrus plants
The genus Cedrus Trew (Pinaceae) compromises four species of evergreen coniferous trees, which have important cultural, aesthetic, scientific and economic values. The four species are disjunctively distributed in the Mediterranean region and western.....»»
Drowning tomatoes for science
I can barely hear Esther Ngumbi over the roar of greenhouse fans as she shows me around her rooftop laboratory in Morrill Hall. The benches are full of tomato plants, and the tomatoes don't look good. Half of the plants are submerged in bins of water.....»»
Molecularly imprinted polymers help get the stink out of smoke-tainted wine
Wildfires can damage crops, even if flames come nowhere near the plants. One outcome can be an unpleasant flavor and smell of wine that is made from grapes exposed to smoke. But researchers report in the Journal of Agricultural and Food Chemistry tha.....»»
A chloroplast-mimicking nanoreactor for enhanced CO₂ electrocatalysis
Chloroplast, which is a double-membrane-bounded organelle, is the main site for CO2 fixation via photosynthesis in green plants. The double-membrane configuration can regulate the transport of substances into and out of the chloroplasts with the aid.....»»
New moves for self defense—how plants can inspire future soft robotic design
For plants, cleaning the air, providing food and medicines, and preserving our ecosystem is just another day's work. In the Department of Mechanical Engineering at Carnegie Mellon University, however, plants are being studied in new ways to inspire f.....»»
Plant signaling pathways decoded using "optogenetic" tobacco plants
Using newly generated "optogenetic" tobacco plants, research teams from the University of Würzburg's Departments of Plant Physiology and Neurophysiology have investigated how plants process external signals......»»

International report confirms record-high global temperatures in 2023
Greenhouse gas concentrations, the global temperature across land and the ocean, global sea level, and ocean heat content all reached record highs in 2023, according to the 34th annual State of the Climate report......»»
Darwin"s fear was unjustified: Study suggests fossil record gaps not a major issue
Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are destroyed by erosion). As a result, the fossil re.....»»
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.....»»
Research sheds light on low crop yields and their impact on small farms
Northeastern University professor Gabriela Garcia studies the relationship between people and plants......»»
From leaf to cup: The essential role of magnesium in tea plant metabolism
Magnesium plays a vital role in the growth and quality of tea plants, influencing key processes such as photosynthesis and the synthesis of important metabolites. However, tea plants often suffer from magnesium deficiency due to factors like poor soi.....»»
Astrophysicists use AI to precisely calculate universe"s "settings"
The standard model of the universe relies on just six numbers. Using a new approach powered by artificial intelligence, researchers at the Flatiron Institute and their colleagues extracted information hidden in the distribution of galaxies to estimat.....»»
Manganese nanoparticles can more than double availability of world"s potable water, say scientists
Manganese ferrite nanoparticles could lead to a substantial surge in the availability of drinking water globally when used to modify the filtering sheets currently used in water treatment plants, according to scientists......»»
This bird species was extinct in Europe. Now it"s back, and humans must help it migrate for winter
How do you teach a bird how, and where, to fly? The distinctive Northern Bald Ibis, hunted essentially to extinction by the 17th century, was revived by breeding and rewilding efforts over the last two decades. But the birds—known for their distinc.....»»
COVID shot now or later? Just getting it at all is great, officials respond.
As the summer wave peaks, officials are prepping for the coming winter wave. Enlarge / A 13-year-old celebrates getting the Pfizer-BioNTech COVID-19 vaccine in Hartford, Connecticut, on May 13, 2021. (credit: Getty | JOSEPH PRE.....»»
Yeast meiosis study finds temperature changes result in shorter meiotic chromosome axes and more crossovers
In a study of meiosis in budding yeast, a research team found that yeast senses temperature changes by increasing the level of DNA negative supercoils to increase crossovers and modulate chromosome organization during meiosis......»»
Extreme rainfall event study demonstrates improved forecasting via physics-guided machine learning
A research team focused on the extreme rainfall event of "21·7" in Henan in 2021. By analyzing anomalous physical characteristics and understanding multi-model forecast biases, they significantly enhanced the accuracy of precipitation intensity fore.....»»
Exploring bamboo charcoal"s slow-release properties for enhanced anti-acne formulations containing bamboo vinegar
Bamboo vinegar is a concentrated liquid obtained from bamboo under high temperature and anaerobic conditions. It contains more than 200 organic components, including organic acids, phenols, ketones, alcohols, and esters, among which acetic acid is th.....»»
