Plants often experience multiple stresses to which they adapt by mounting specific responses. Nitrogen supply allows plants to better recover from drought, and this is linked to inhibition of the SnRK2 kinase, which is shown to destabilize the NLP7 master transcription factor for nitrate signals.

Saturn’s icy moon Enceladus just revealed stunning new clues to life

Anonymous, 02/10/2025 | Source: Agriculture and Food News -- ScienceDaily

Fresh analysis of Cassini data has revealed new complex organic molecules inside ice grains spewing from Enceladus. These discoveries strengthen the case that the moon’s underground ocean hosts chemistry similar to life’s building blocks on Earth. Scientists now believe Enceladus could be habitable, and plans are underway for a European mission to sample its surface and jets.

Pollen holds a secret that could save honeybees

Anonymous, 30/09/2025 | Source: Agriculture and Food News -- ScienceDaily

Scientists have discovered that pollen is a hidden source of natural medicine for honeybees. Symbiotic bacteria called Streptomyces produce antimicrobial compounds that fight deadly bee and plant pathogens. Bees collect these bacteria along with pollen and store them in hives, creating a natural defense system. This could lead to new, sustainable ways of protecting both pollinators and crops.
