PandaX-II seems to slightly strengthen XENON1T's hints of dark matter particles
The recent Chinese 3D remake of the legendary cute Czech Little Mole features a new, bigger friend of the Central and Eastern Europe, I mean of the little mole, namely the People's Republic of China, I mean a big fat panda. ;-) This was the first episode among many.
This blog post is very brief because I don't think it's a good investment of time to write full-blown texts. But as you know, the hints of any new particle behind the Standard Model are extremely weak or almost non-existent.

It may be explained by the boring tritium junk or by the exciting axions or magnetic neutrinos. See a July paper that analyzes the excess and tries to explain it.
Now, a similar Chinese experiment
