【soft Matter Lecture 134】Chemical Tools to Study Biological Systems
Finnish utility Fortum and Westinghouse Electric Company of the USA have signed a memorandum of understanding to explore prerequisites for the development and deployment of new nuclear in Finland and ...
If we could rewind the tape of species evolution around the world and play it forward over hundreds of millions of years to the present day, we would see biodiversity clustering around regions of tect...
A better way to study ocean currents（图）
洋流 机器学习模型 塑料污染 漏油
2023/6/20
To study ocean currents, scientists release GPS-tagged buoys in the ocean and record their velocities to reconstruct the currents that transport them. These buoy data are also used to identify “diverg...
