Scientists document how essential oils can be used as natural fungicides
Essential oils are concentrated, phytonutrient-rich extracts that capture the scent and flavor of plants. They are usually obtained through distillation or mechanical methods like cold pressing. Essential oils are known for their many uses, such as in aromatherapy, where they are said to help relieve pain and reduce stress and anxiety. Some of these useful natural […]

Bats can anticipate their prey’s movements by building predictive models on the fly, says new study
Despite possessing better vision than humans at night, some bats prefer to use their advanced hearing to hunt for food. These nocturnal creatures manufacture sounds and rely on the echoes those sounds make while bouncing off objects to navigate in the dark and find their prey. This ability, known as echolocation, is a subject of particular interest […]

CO2 to the rescue: Elevated carbon dioxide concentrations can reduce the negative effects of drought on crops, study finds
American and Brazilian researchers evaluated the possibility of elevated carbon dioxide (CO2) concentrations reducing the negative effect of drought on physiological parameters and the growth of Manihot esculenta (cassava). They reported their findings in an article published in the journal Archives of Agronomy and Soil Science. The researchers grew cassava with 390 ppm or 750 ppm of CO2 […]

Bacterial populations use seepage water to travel between the surface and subsoils
In this study, German researchers investigated the mobilization of certain bacterial populations present in the soil after dynamic hydraulic events. Their findings were published in the journal Soil Biology and Biochemistry. During extreme precipitation events, substantial amounts of organic matter are mobilized, resulting in fluxes in carbon from the topsoil to deeper mineral soil and groundwater. […]

Cadmium and zinc exhibited strong bioaccumulation and mobility capacity from soil to rice
In this study, Chinese researchers investigated the bioaccumulation and transfer of heavy metals from soil to plants, as well as the effects of soil properties on these events. They reported their findings in an article published in the journal Acta Agriculturae Scandinavica, Section B — Soil & Plant Science. The researchers conducted their study on a […]

High levels of toxicants from plastic products found in stranded dolphins and whales
Consumer waste like plastics pose a huge threat to marine life for various reasons. Apart from their durability and slow biodegradability, plastics also contain and attract toxic contaminants that can accumulate inside aquatic animals if they’re ingested. Over the past few decades, scientists have been sounding the alarm on the increasing amount of plastics found polluting the world’s oceans. A new […]

Researchers suggest adding biofertilizers to soil to improve yield
Biofertilizers are substances containing living microorganisms or their natural products, which are applied to seeds, soils and crops. These natural fertilizers are known for their ability to increase plant nutrient content and improve the biological properties of soil. Biofertilizers are more preferable than chemical fertilizers as they are environmentally sustainable and cost-effective. Synthetic fertilizers, on the […]

Researchers study how pepper-rosmarin essential oil inhibits the growth and germination of conidia of Bipolaris maydis
In this study, researchers from the Federal University of Tocantins in Brazil evaluated the efficacy of four different essential oils in inhibiting the mycelial growth and the germination of the conidia of Bipolaris maydis. Their findings were published in the Journal of Medicinal Plants Research. Natural plant disease control agents represent a great option with beneficial effects on […]

Arsenic is toxic to humans, but these microbes live and breathe it
Researchers from the School of Oceanography at the University of Washington have discovered how some microorganisms that live in portions of the ocean where oxygen is almost absent manage to thrive. Called marine oxygen-deficient zones (ODZs), these regions are sandwiched between the oxygen-rich surface and the deep layers. In their study, which appeared in the […]

The grass is always greener (and the soil is healthier) on the side of conservation agriculture
Conservation agriculture (CA) practices are adaptable and can be customized to the requirements of crops and local conditions. While this farming system considers soil health and the impact it has on the ecosystem, it is not without its disadvantages. The early days of CA implementation may present various problems, such as nitrogen immobilization and weed interference. Both […]
