Phys.org October 10, 2024 Most of the world’s lakes freeze, with a median ice duration of 218 days. The rate of lake ice loss has markedly accelerated over the past 25 years, with ice melt in some regions across the Northern Hemisphere arriving 45 days per century earlier and with many lakes experiencing increased intermittency of ice cover during winter in addition to ice-free winters. Lake ice loss is expected to affect a substantial proportion of the world’s population. Until recently, both logistical challenges as well as misconceptions of winter as a time of quiescence resulted in limited winter research. […]

A new species of darkling beetle larvae that degrade plastic
Science Daily July 20, 2020 Researchers in South Korea found that the larvae of a darkling beetle P. davidis indigenous to East Asia, including the Korean peninsula, can consume polystyrene and reduce both its mass and molecular weight. They confirmed that the proportion of Serratia bacillus in the intestinal tract of P. davidis larvae was responsible for six-fold increase in biodegradation. It was found that the gut flora of this larvae consisted of a very simple group of bacterial species unlike the gut flora of other conventional polystyrene-degrading insects. According to the researchers if we replicate the simple gut floral […]
