Electric Plants And That Pesky Hubble Constant
New Supernovae Analysis Supports Hubble Tension
A paper that was published just a week ago analyzed a large catalog of supernovae and several other data sets. They confirmed that different combinations of data sets have different preferred values for the Hubble constant (H0). This supports what has become known as the “Hubble Tension”, which is arguably the most-discussed anomaly in cosmology right now. More here.

Electric Sparks from Plants Change Air Quality
Plants in a thunderstorm can emit electric discharge that leads to an emission of molecules which, among others, can bind to methane or create ozone. It’s believed to be a small effect (compared to the effect of the thunderstorm itself) but researchers are trying to understand better how relevant it is for air quality. More here.
New Computation Will Probably Reduce Muon Anomaly
The measured value of the magnetic moment of the muon is currently 4.2 σ away from the theoretical calculation. While some think the anomaly might be a sign for new physics, many physicists believe that the problem is just that the calculation is really difficult. A new paper seems to confirm the latter. More here.
In this week’s video, I look at what it means if an effect comes before the cause, and the Transactional Interpretation of Quantum Mechanics
