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.

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.

Every year, respiratory syncytial viruses (RSV) cause countless respiratory infections worldwide. For infants, young children and people with preexisting conditions, the virus can be life-threatening. The team has explored ways to reduce the risk of infection. Their findings show that -- when used correctly -- alcohol-based hand sanitizers and commercially available surface disinfectants provide good protection against transmission of the virus via surfaces.

Cancers, degenerative diseases: deregulation of our cells' internal communication pathways is at the root of many conditions. Microtubules -- microscopic protein filaments -- play a crucial role in controlling these exchanges. However, their mechanisms remain poorly understood. A team has identified a new mechanism, involving two proteins, that governs their growth. The discovery opens up unprecedented prospects for the development of new treatments that can act at the very heart of cells.

Resistant starch is a nondigestible fiber that ferments in the large intestine, and consumption of it has previously been shown to have a positive effect on metabolism in animal studies. Now, a 4-month randomized controlled trial in people with non-alcoholic fatty liver disease (NAFLD) indicates that daily intake of resistant starch can alter gut bacteria composition and lower liver triglycerides and liver enzymes associated with liver injury and inflammation.

A 'living material,' made of a natural polymer combined with genetically engineered bacteria, could offer a sustainable and eco-friendly solution to clean pollutants from water. Researchers developed their living material using a seaweed-based polymer and bacteria that have been programmed to produce an enzyme that transforms various organic pollutants into harmless compounds. In tests, heir material decontaminated water solutions tainted with a pollutant from textile manufacturing: indigo carmine, a blue dye that is used to color denim.

NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.

Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.

Patulin is a harmful mycotoxin produced by fungi typically found in damaged fruits, including apples, pears, and grapes. 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.
