A recent study from Guam found that non-native Acacia trees alter the soil chemistry and root-zone nutrient budgets, causing collateral ecosystem deviations. The results contribute to ongoing global discussions about afforestation for revegetating tropical degraded habitats.
Researchers have developed a metal-organic framework (MOF) material that can regulate humidity levels within a specific range. The material, Y-shp-MOF-5, takes up water in dry air but releases it when the relative humidity falls below 45%. This autonomous behavior maintains optimal humidity levels between 45-65%.
A team at RMIT University in Melbourne, Australia has developed an asphalt mixture with encapsulated cigarette butts, reducing thermal conductivity and handling heavy traffic. The innovation could solve a huge waste problem while also mitigating the urban heat island effect common in cities.
Researchers at King Abdullah University of Science & Technology have identified three traditional Saudi plants with potent anticancer substances, including topoisomerase inhibitors. The study suggests these compounds could be used to develop novel cancer treatments, but more research is needed before they can be tested in humans.
