Researchers have investigated how the behavior of an individual wheat plant under limiting light conditions influences the performance of the whole community. They assessed morphological and biomass phenotypes of single plants grown in mixtures under sunlight and a simulated canopy shade, and the relevance of these phenotypes for the monoculture community in the field.

Mold and diseases caused by fungi can greatly impact the shelf life of fruit and vegetables. 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.

Researchers scientists have unlocked a new realm of possibilities for non-volatile phase change memory, a type of electronic memory capable of retaining data even without power. Traditionally, researchers have relied on chalcogenides, materials with reversible electrical properties during transitions between crystalline and amorphous states. But an exciting alternative has emerged in the form of layered nickelates, complex oxide materials composed of nickel ions. These nickelates, with their unique layered structure and thermally reversible switching of room-temperature electrical resistivity, offer superior performance and sustainability potential.

Farmers usually plant so-called cover crops after harvesting their main crop in the Fall. This prevents erosion of the soil and nutrient leaching. The roots of these crops also stabilize the structure of the soil. It had been assumed up to now that a mixture of different cover crops would result in particularly intensive rooting. However, a recent study found only limited evidence that this is the case. Instead, mixed cover crops grow thinner roots than when just one single type of cover crop is planted. This result was unexpected. It documents how little is currently understood about the interactions between plant roots.

Plant-based alternatives such as tempeh and bean burgers provide protein-rich options for those who want to reduce their meat consumption. However, replicating meat's flavors and aromas has proven challenging, with companies often relying on synthetic additives. A recent study unveils a potential solution: onions, chives and leeks that produce natural chemicals akin to the savory scents of meat when fermented with common fungi.

If the region surrounding Chicago -- North America's largest freight hub -- shifted just 30% of its current on-road heavy-duty vehicles to electric versions, it would substantially reduce pollution and save hundreds of lives per year, with the benefits largely concentrated in disadvantaged communities, according to a new study. The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.

Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.

Simultaneous wireless information and power transfer (SWIPT)-aided nonorthogonal multiple access (NOMA) system, used for communication in the Industrial Internet of Things (IIoTs), suffers from significant energy loss with transmission distance. Now, researchers have developed an energy-efficient framework by applying SWIPT-NOMA to a distributed antenna system. This technology is expected to pave the way for more efficient and optimized IoT environments.

Tropical forests in South America lose their ability to absorb carbon from the atmosphere when conditions become exceptionally hot and dry, according to new research. For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the impact of climate change. But new research found that in 2015 -- 2016, when an El Niño climate event resulted in drought and the hottest temperatures ever recorded, South American forests were unable to function as a carbon sink.
