Ghosts of past pesticide use can haunt organic farms for decades
Although the use of pesticides in agriculture is increasing, some farms have transitioned to organic practices and avoid applying them. But it's uncertain whether chemicals applied to land decades ago can continue to influence the soil's health after.....»»
From trash to treasure: Machine learning enhances organic waste recycling
Biological treatment methods such as anaerobic digestion, composting, and insect farming are essential for managing organic waste, converting it into valuable resources like biogas and organic fertilizers. However, these processes often face challeng.....»»
The unintended consequences of success against malaria
For decades, insecticide-treated bed nets and indoor insecticide spraying regimens have been important—and widely successful—treatments against mosquitoes that transmit malaria, a dangerous global disease. Yet for a time, these treatments also su.....»»
Examining progress on volatile organic compound pollution control via the catalytic method
Volatile organic compounds (VOCs), with toxicity and irritability, could cause atmospheric environmental problems such as haze and photochemical smog, seriously threatening the ecological environment and human health. The primary source of VOCs is hu.....»»
Woodchip bioreactor helps reduce pesticide run-off from horticulture greenhouses
Pesticides seeping out of intensive horticulture into waterways have long-concerned NSW north coast communities. Now a new Southern Cross University study provides evidence that bioreactors can significantly limit this toxic run-off......»»
New car smell reaches toxic levels on hot days, researchers find
A study of volatile organic compounds (VOCs) emitted by new cars on hot summer days finds concerning levels of formaldehyde and other aldehydes......»»
As a reviewer, here’s why I recommend Norton over McAfee for most people

Organic polymer blend microspheres exhibit ultra-low threshold lasing with highest reported quality factor
Researchers at IMDEA Nanociencia have fabricated high quality microspheres from conjugated organic polymer blends with excellent lasing properties. The laser emission of the microspheres has the highest quality factor reported to date, Q>18,000......»»
Humans caused climate change. Amid the suffering, now they must solve it
For decades, scientists warned that continued burning of oil, gas, and coal would have devastating climate impacts. Those impacts are being felt around the world......»»
The winner in China"s panda diplomacy: the pandas themselves
China's panda diplomacy may have one true winner: the pandas themselves. Decades after Beijing began working with zoos in the U.S. and Europe to protect the species, the number of giant pandas in the wild has risen to 1,900, up from about 1,100 in th.....»»
Chemists develop a stable reagent for carbon-atom transfer
Professor Max Martin Hansmann from the Department of Chemistry and Chemical Biology and his team have developed a new reagent for selectively adding carbon atoms to molecules. This promising development for basic research in organic chemistry has bee.....»»
Sustainable irrigation critical to recovery of Ukrainian farms, a major global exporter of grain and oilseeds
By the middle of the century, three-quarters of Ukrainian croplands—a critical source of the world's grain and oilseeds—will experience water shortages due to the combination of climate change and infrastructural damage caused by the Russian inva.....»»
Signatures of life could survive near surfaces of the moons Enceladus and Europa, NASA experiment suggests
Europa, a moon of Jupiter, and Enceladus, a moon of Saturn, have evidence of oceans beneath their ice crusts. A NASA experiment suggests that if these oceans support life, signatures of that life in the form of organic molecules (e.g. amino acids, nu.....»»
Studies explore converting wastewater to fertilizer with fungal treatment
Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temp.....»»
Better dams offer major benefits to farmers and livestock
Managing the water quality of farm dams is critical to the health of livestock as well as boosting crop production, according to new research from the Sustainable Farms group at The Australian National University (ANU)......»»
Material with molecular trapdoor holds promise for highly selective gas adsorption
An international team led by scientists at City University of Hong Kong has found a flexible metal-organic framework (MOF) with one-dimensional channels that acts as a "molecular trapdoor" to selectively adsorb gases, such as carbon dioxide, in respo.....»»
Diatom surprise could rewrite the global carbon cycle
When it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide.....»»
Discovery alert: With six new exoplanets, 5,500 discovery milestone passed
On Aug. 24, 2023, more than three decades after the first confirmation of planets beyond our own solar system, scientists announced the discovery of six new exoplanets, stretching that number to 5,502. From zero exoplanet confirmations to more than 5.....»»
TinyPod transforms your Apple Watch into a mock iPod
TinyPod is a revival of the iPod, an enclosure that turns the Apple Watch into a compact version of the portable music device.The TinyPodApple officially discontinued the iPod in May 2022 after over two decades of availability. In one new accessory t.....»»
Organic compounds show promise as cheaper alternatives to metal photocatalysts
Organic compounds that can be sustainably and affordably mass-produced show promise as replacements for expensive metal photocatalysts, according to a new report published July 17......»»
Paving the way to extremely fast, compact computer memory
