Cost analysis of using cover crops in citrus production

The citrus industry in Florida, a historic hub for citrus (Citrus sp.) production, has been grappling with the devastating effects of Huanglongbing (HLB), also known as citrus greening disease (Candidatus Liberibacter asiaticus). In the face of this challenge, a recent study delves into the potential economic viability of incorporating cover crops in citrus groves to enhance soil health and...

Using agricultural residues for fuel and chemicals

A Lawrence Livermore National Laboratory (LLNL) scientist is part of a research team shedding new light on how to access the sugars locked up in plant materials in order to convert byproducts into new feedstocks for production of fuels, materials and chemicals.

Team develops a laser printer for photonic chips

Photonic integrated circuits are an important next-wave technology. These sophisticated microchips hold the potential to substantially decrease costs and increase speed and efficiency for electronic devices across a wide range of application areas, including automotive technology, communications, health care, data storage, and computing for artificial intelligence.

Hubble captures a suspected galaxy encounter

UGC 3912 is classified as a spiral galaxy, but you wouldn't know it from this detailed NASA Hubble Space Telescope image. UGC 3912's distorted shape is typically indicative of a gravitational encounter with another galaxy. When galaxies interact—either brush up against each other's gravitational fields or even collide—their stars, dust, and gas can be pulled into new paths. UGC 3912 might have...

New study reveals transformative power of aquaculture in Zambia

A new study led by the University of Stirling has revealed for the first time substantial benefits from adopting smallholder aquaculture for Zambian farmers. The research provides compelling evidence of how fish farming diversifies livelihoods and improves food and nutrition security in rural areas.

Comparing carbon-trapping capacities of anoxic basins

Humans will need to both drastically reduce emissions and remove at least 10 gigatons of carbon dioxide from the atmosphere per year to avoid the worst effects of climate change, according to the Intergovernmental Panel on Climate Change 2023 synthesis report.

Innovative portable sensors for hydrogen peroxide detection

In a study published in the journal Microsystems & Nanoengineering, researchers from Northwestern Polytechnical University (NPU) have unveiled a breakthrough in the detection of hydrogen peroxide H2O2, a vital biomarker in biological processes, with the development of dual-functional portable sensors based on Pt-Ni hydrogels.

Permafrost alone holds back Arctic rivers—and a lot of carbon

New research from Dartmouth College provides the first evidence that the Arctic's frozen soil is the dominant force shaping Earth's northernmost rivers. Permafrost, the thick layer of soil that stays frozen for two or more years at a time, is the reason that Arctic rivers are uniformly confined to smaller areas and shallower valleys than rivers to the south, according to a study in the Proceedings...
