In a bright start of a new week I have lost my internet connection. It's expected to be back by 7:10 pm. Until then, the system is down

1. Today the NIH director issued a new directive slashing overhead rates to 15%.

I want to provide some context on what that means and why it matters.

Reminder for new users here:

The spacetime metric is a Lorentzian signature tensor with precisely one negative eigenvalue
Reminder for new users here:

The Higgs field (see below) gives mass to fundamental particles, like the electron and the quarks in protons and neutrons. But most of the mass of protons and neutrons is due to the binding energy of the strong interaction. That thus applies to your body too.
Reminder for new users here:

It is not the Higgs boson that gives mass to fundamental particles but rather the interaction with the Higgs field. The Higgs boson is an excitation of the Higgs field, and through its observation the existence of the Higgs field was confirmed.
