Nano-nutrients can blunt effects of soil contamination, boost crop yields
One of the pressing problems that the world faces in the era of climate change is how to grow enough healthy food to meet the increasing global population, even as soil contamination rises. Research recently published in Nature Food by an internation.....»»
Each glacier has a unique organic matter composition, study reveals
Melting glaciers release more than just water. Organic matter once trapped in ice can run into streams and rivers, where it becomes food for microbes. These organisms respire the organic matter back to the atmosphere in the form of carbon dioxide, wi.....»»
Testing effects of perennial cover crops on soil health and corn production
Corn crops have a voracious appetite for nitrogen. Purdue University scientists are investigating whether mulching Kura clover, a perennial legume, can provide sufficient nitrogen for corn, thus reducing the need for synthetic fertilizers while enhan.....»»
Multicolor persistent luminescent materials for dynamic optical anti-counterfeiting
Optical anti-counterfeiting technology, as a preventive measure, has deeply permeated our daily lives. Visually readable codes designed based on optical materials are widely used due to their ease of verification, reasonable cost, and difficulty in r.....»»
Canopy structure regulates autumn phenology by mediating microclimate in temperate forests, finds study
Autumn phenology serves as a sensitive indicator of temperate forests' response to climate change and is a key factor influencing forest carbon sequestration. Understanding the mechanisms driving the spatiotemporal variations in autumn phenology is c.....»»
How "vaccinating" plants could reduce pesticide use and secure global food supplies
In a growing and changing world, we need to find ways of putting food on everyone's table. Pesticides have enabled mass cultivation on an incredible scale, but they can have harmful secondary effects on humans and wildlife, and pests are rapidly evol.....»»
Seven new frog species discovered in Madagascar
An international team of researchers have discovered seven new species of tree frogs that make otherworldly calls in the rainforests of Madagascar. Their strange, high-pitched whistling calls sound more like sound effects from the sci-fi series "Star.....»»
Washington state"s older forests capture carbon better than nearly any other
They tower and drip, their curtains of moss damp in windblown fog: rainforests of the Pacific Northwest, unique in all the world......»»
China"s child policies will increase its future carbon emissions, researchers say
Relaxing its restrictions on family size would make it more difficult for China to achieve its goal to be carbon neutral by 2060, according to a new study by UCL researchers......»»
Eyeing the damage of hurricane season
In the aftermath of hurricanes like Helene and Milton, the damaging effects of these natural disasters are the center of national conversations, including questions about the long-term impact to infrastructure. However, current methods for damage ass.....»»
Carbon capture has a place in Illinois" climate-change toolkit
Approaching downstate Decatur by car, it's not unusual to smell the huge Archer Daniels Midland industrial complex before seeing it. The sweet aroma of fermenting grain wafts through vehicle windows and air vents, a sign that ethanol fuel is being br.....»»
Scientists develop a new method to study gene function in cells and tissue
The Gaublomme lab has developed a new optical pooled screening approach called CRISPRmap, which enables the coupling of optical properties of single cells to targeted genetic perturbations. Optical phenotypes are typically inaccessible for sequencing.....»»
Researchers create a three-dimensional multi-focus laser for glass micro-sculpting
Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with feature sizes ranging from several micrometers to hun.....»»
Powerful and compact optical frequency combs provide unique opportunities
Remember those big, clunky machines needed for super precise light measurements? Those days are fading thanks to tiny devices called microcombs. These chips can do the same job, but on a much smaller scale, opening doors for new applications......»»
Harnessing quantum principles: Phased arrays within phased arrays for smarter, greener indoor optical wireless networks
