Research and anti-cancer effects of new indole alkaloid derivatives

Cancer is a group of diseases characterized by uncontrolled development and the spread of abnormal cells. An estimated 14 million new cases of cancer are reported each year worldwide. In 2017, about 600,920 American people die from cancer, with nearly 1,650 deaths each day. Some typical natural compounds, such as alkaloid indole, show significant anti-cancer activity. Periwinkle alkaloid, a family of indole dimer compounds isolated from the periwinkle of Catharanthus roseus, the Apocynaceae family, represents one of the most important anti-cancer layers.

Bats reported due to hot sun in some northern urban areas

The North has been experiencing record summer temperatures for more than 40 years, with many places exceeding 40 degree Celcius. Combined with the impact of the "urban heat island" effect, the average heat at the same time in the big cities like Hanoi is harsher. The effect of hot weather on the life and activities of people, especially in urban areas, has been mentioned by many news agencies. However, the impact of these extreme weather phenomena on the living creatures in the urban environment receives less research.
