However, some fungi benefit their hosts by aiding plant survival. Colletotrichum tofieldiae (Ct) is a root mold which typically supports continued plant development even when the plant is starved of phosphorus, an important nutrient for photosynthesis and growth. Researchers studied a unique pathogenic strain of the fungi, called Ct3, which conversely inhibits plant growth.

As the share of volatile renewable energy needing electricity storage increases, more and more LIBs are needed, lithium prices rise, resources dwindle, and the amount of depleted batteries that contain toxic substances increases. Researchers introduce a novel approach for the recovery of lithium from used LIBs.

In a recent breakthrough, researchers identified a new filamentous fungal strain that can degrade patulin by transforming it into less toxic substances. Their findings provide important insights into the degradation mechanisms for patulin found in nature, and can lead to new ways of controlling patulin toxicity in our food supplies.

The surrounding habitat, not temperature, is the important driver of methane emissions. The findings could improve methane estimates and models of climate change, and point to land-management changes and restoration opportunities that can reduce the amount of methane escaping into the atmosphere.

Scientists found that if you add tannins (natural plant compounds that make your mouth pucker if you bite into an unripe fruit) to a layer of wood dust, you can create a filter that can trap virtually all microplastic particles present in water. While the experiment remains a lab set-up at this stage, the team is convinced that the solution can be scaled up easily and inexpensively.

But while aloe sap is in high demand, the peels are thrown away as agricultural waste. Now, after identifying several bioactive compounds in extracts from the peels that deter insects from feasting on crops, scientists report that these peels can act as a natural insecticide.

Scientists have designed catalyst-coated lampshades that transform indoor air pollutants into harmless compounds. The lampshades work with halogen and incandescent light bulbs, and the team is extending the technology so it will also be compatible with LEDs.

But researchers have developed special iron oxide nanoparticles called 'smart rust' that actually makes it cleaner. The magnetic nanoparticles attract different pollutants by changing the particles' coating and are removed from water with a magnet. Now, the team is reporting a smart rust that traps estrogen hormones, which are potentially harmful to aquatic life.

But do these delightful summertime activities have an impact on waterways? Now, the first holistic study of this question has found that recreation can alter the chemical and microbial fingerprint of streams, but the environmental and health ramifications are not yet known. Wed, 16 Aug 2023 11:41:58 EDT //www.koonmotors.com/releases/2023/08/230816114158.htm //www.koonmotors.com/releases/2023/08/230814122405.htm Imagine using insects as a source of chemicals to make plastics that can biodegrade later -- with the help of that very same type of bug. That concept is closer to reality than you might expect. Researchers will describe their progress to date, including the isolation and purification of the insect-derived chemicals and their conversion into their bioplastics.

Designed as a tool to be used in practice, the model identifies measures and areas that are priorities for promoting human-bear coexistence. The model is being applied to the Abruzzo, Lazio and Molise national parks, but can also be used for other regions and large carnivores.

After all, they have made a significant contribution to improving the quality of natural waters. A study shows, however, that substances still manage to enter the water cycle that have an impact on the composition of the organisms living in it.

In the end, only about 9 percent of plastic in the United States is ever reused, often in low-value products. With a new technique, however, chemical engineers are turning low-value waste plastic into high-value products.

The tremors are produced by the same processes that could create large, damaging earthquakes.

The fabric, a blend of plastic and cotton, has been difficult for the industry to separate and therefore recycle. Now, a group of young chemists has invented a green and surprisingly simple solution using a single household ingredient.

Hence, it is largely removed in a coordinated manner within a few weeks. However, it can litter other coasts of the world for many months to years due to unregulated waste disposal. Often the garbage on the beach is simply burned and a special form of plastic waste is created: so-called plastiglomerate. This 'rock' is made up of natural components, such as coral fragments, held together by the melted and reconsolidated plastic. A new study has now demonstrated, using field samples from Indonesia, that such rocks pose an increased environmental risk to coastal ecosystems such as seagrass beds, mangroves or coral reefs. The melted plastic decomposes more quickly into microplastics and is also contaminated with organic pollutants.

The hope was that water quality would improve by reducing the nitrogen load. While these restrictions were well-intended, a study finds fertilizer use is not the root cause of the lagoon's environmental issues. It's sewage. For decades, fertilizer use was implicated for about 71 percent of the lagoon's environmental impairments. In fact, current estimates show 79 percent of nitrogen loading is from septic systems; 21 percent is from residential fertilizer use.

Little is known about if and how microbes can use NO as a substrate for growth. Scientists have now managed to grow a microbial community dominated by two, so-far unknown species on NO for more than four years (and counting) and study their metabolism in great detail. Their research provides insight into the physiology of NO-respiring microorganisms, which have pivotal roles in the control of climate active gases, waste removal, and the evolution of nitrate and oxygen respiration.

The team's work advances other methods for heavy-metal removal by recycling the acidic liquid waste that is produced during the recovery phase, instead of throwing it away.

Since then, hundreds of cities across the world have published their own climate action plans (CAPs), detailing how their urban areas will handle climate change. How do the plans stack up against one another and against the recommended guidelines established by the United Nations-Habitat Guiding Principles for City Climate Action Planning?

Interestingly, certain species of ants are also avid gardeners, a practice they've refined over 50 million years. They too weed their underground fungus gardens, but how they know what to weed out has been a mystery. Now, a multidisciplinary team of scientists report how ants distinguish the good fungus from the bad. Fri, 16 Jun 2023 16:19:13 EDT //www.koonmotors.com/releases/2023/06/230616161913.htm
