最近、隕石中に太陽系誕生以前の物質が含まれていることが明らかになった。この物質は化学組成からでは判別することができず、同位体組成によってのみ特定できる。この物質の研究を進めることにより、太陽系の起源でとぎれていた我々の歴史が宇宙史の中に位置づけられる日が来るだろう。

During the eighteenth century, large numbers of Chinese laborers came to work in mines in the Northern Uplands of Vietnam. However, few investigations have been conducted on the responses of native chieftains or the local population to the social fluctuations in this area. Therefore, this article focuses on the survival strategies of native chieftains in the Lang Son region. Investigation of correspondence between the Lê-Trinh government and native chieftains in the Lang Son region reveals that under this government's control, native chieftains were tasked with collecting taxes and drafting soldiers in each commune. They were permitted to receive a portion of these tax revenues as salary and collect various fees via taxation, causing them to perceive these roles as their own vested rights. Meanwhile, during the mid-eighteenth century, the Lang Son region was involved in extensive disturbances that destabilized the native chieftains' political and economic bases. Given this background, the Lê-Trinh government frequently sanctioned the aforementioned rights of native chieftains by issuing official documentation, while the chieftains themselves also requested the government to issue official documents confirming their rights. In fact, they possessed these documents until the colonial era or transcribed them in their genealogies, demonstrating that they recognized them as certifications of their vested rights. Thus, during the eighteenth century, developing relations with the Lê-Trinh government was a survival strategy for native chieftains in the Lang Son region.

To elucidate the diapause pattern of Lepisma saccharina Linnaeus, strains collected in Hirosaki were kept under controlled conditions of photoperiod and temperature. The interval between moults was uniformly short in the first two instars, but tended to increase in the later instars and showed a very large variation owing to the occurrence of diapause in some individuals but not in others. When reared at 25℃, this insect started oviposition in the 9th or 10th instar but thereafter continued to grow and moult. Some individuals survived 2.5 years or more and moulted more than 30 times. The incidence of diapause as defined by the instar duration of longer than 50 days was affected by temperature, photoperiod and age. The duration of diapause was highly variable among individuals, lasting more than 180 days at 25℃ in extreme cases. Diapause may occur in any larval and adult instar but not in the first two instars, and may be repeated in separate or consecutive instars. Some individuals underwent 8-9 diapause instars in 600-800 days. At 20℃, diapause occurred in the younger (3rd and 4th) instars at a higher frequency, and a photoperiodic response of the long-day type was manifested more clearly, than at 25℃. A high temperature of 28℃ prevented diapause at least in the larval stage under both short (12h) and long (16h) photoperiods.
