●Recently, a new study of more than 5,500 adult e-cigarette users found that e-cigarette use is highly correlated with the prevalence of fragility fractures. Studies have shown that e-cigarette use may be harmful to bone health, even for young people. Fragility fractures are fractures of the hip, spine or wrist caused by minor trauma (such as falling from standing height or lower). (Source: Science and Technology Daily)

●Scientists have found that from 1939 to 2010, climate warming led to an accelerated renewal rate of alpine shrubs of the genus Willow on the Qinghai-Tibet Plateau. The shrub line of the genus Willow rose significantly, with the maximum rise of 59.3 meters. In the past 10 years, the renewal rate of alpine shrubs of the genus Willow has been declining, and the shrub line tends to remain static. The relevant results were recently published in the international academic journal Ecological Geography. (Source: Xinhua News Agency)

●Recently, Tree Physiology published online the latest results of Zhou Zhichun's research team from the Institute of Subtropical Forestry, Chinese Academy of Forestry. They cloned and identified the geranyl pyrophosphate synthase gene (PmGPPS1) in the highly resistant Masson pine for the first time, and analyzed the regulatory role of PmGPPS1 in the process of highly resistant Masson pine resisting pine wilt disease. The research results provide new ideas for the green prevention and control of pine wilt disease, and also provide new ways to promote plant leaf growth. (Source: China Science Daily)

●The results of a study published on the website of the Hebrew University of Israel on the 21st showed that the condition of patients with severe COVID-19 was significantly improved after the use of colchicine to treat the patients; compared with patients not treated with the drug, the mortality rate of COVID-19 patients treated with colchicine dropped by 50%. The study was jointly conducted by researchers from the Hebrew University and Hadassah Medical Center in Israel, and the research results have recently been published in the European Journal of Internal Medicine.
