2022 too short, too far: DTE’s coverage of scientific developments worldwide

Science marched on in the year 2022, with several new discoveries in the fields of physics, chemistry, biology and other disciplines. We learnt about whether the human race would actually go extinct due to the disappearing Y chromosome. There were strides in the field of using animal organs in humans. Finally, there were developments in the field of space science.

Below is a selection of Down To Earth stories on scientific developments worldwide:
