#2021世界地球日# 在全球范围内，比特币的年化碳足迹为36.95Mt CO2，相当于新西兰的碳足迹；电能消耗77.78TWh，与智利一致；电子垃圾10.96kt，与卢森堡的电子垃圾产生量相当。终究有一天太阳能电池挖矿将会实现，也许有一天，每家每户都会经营自己的太阳能动力矿机，邻里之间作为矿池，挖比特币就像水龙头里流出来的水一样平常。

情况已经不容乐观，前不久台积电将飞腾的产能空出，用车用芯片填补了空缺，最近台积电又限制了新的多家企业芯片供应。可以说，台积电的态度很明确，表示会一如既往遵守所有法律和法规，现在台积电依旧生产线满载运作，但国内很多企业已经捉襟见肘。最新断供的企业Phytium Information Technology Co，为中国三大超级计算机项目之一天河三号，提供了重要的组件，其中光Phytium MT2000+和Phytium FT2007处理器就占了相当大的比重。现在台积电没办法为其生产处理器了，百亿级的超级计算机天河三号的效果肯定就大打折扣了，虽然说日韩等其他国家有替代品，但就目前情况来看最好的部件仍然来自美国。

#Drug Research# Kusunoki et al conducted this study to determine whether additional administration sodium-glucose co-transporter 2 (SGLT2) inhibitor might provide further improvement of glycemic control and also to explore any advantages in Japanese type 2 diabetes patients showing relatively good glycemic control under treatment dipeptidyl peptidase-4 (DPP-4) inhibitors. The authors divided the patients in two groups, MT group and CT group. The MT group were continued on the DPP-4 inhibitor treatment for 6-months, and CT group were additionally administered an SGLT2 inhibitor treatment for 6-months.
