In a study published in npj Clean Water, researchers from EPFL investigated how Escherichia coli responds to different concentrations of plasma-activated water (PAW) under nutrient-rich conditions. The team combined conventional colony-forming unit (CFU) counting with nanomotion sensing, a technique that detects nanoscale oscillations produced by metabolically active bacteria.

Youth hubs and 'third spaces' for young people are being touted as solutions to growing concerns about youth crime, loneliness and radicalisation. Three recent NSW parliamentary inquiries have all recommended further investment in youth hubs and other programs to strengthen belonging and address isolation. Youth hubs are community spaces staffed by qualified youth workers, where young people can build connections with peers and mentors.

American beech trees may carry genetic resistance to deadly leaf disease

A study led by scientists at the Holden Arboretum has found evidence that beech leaf disease (BLD) symptom development is genetically controlled, providing the first evidence that some American beech trees may have genetic resistance. This finding supports further investigation and development of breeding populations for BLD resistance. Nearly a third of beech trees near BLD's epicenter in northeastern Ohio, the majority of which were smaller trees, have died since the disease was discovered...
