Early Monitoring of Forest Wood-Boring Pests with Remote Sensing.
Wood-boring pests (WBPs) pose an enormous threat to global forest ecosystems because their early stage infestations show no visible symptoms and can result in rapid and widespread infestations at later stages, leading to large-scale tree death. Therefore,

Chemistry of alkaline earth metals: It is not all ionic and definitely not boring!
Some scientists might consider group 2 chemistry as “boring, closed shell and all ionic, aqueous chemistry, where everything is known! It is not worth investigating”. How wrong they are! Far from forming only purely ionic compounds, this review will shed
