Chemistry
There is a lot of great information like NMR shifts and physical constants related to Organic Chemistry on this site by Prof. Hans Reich at the UW Madison
Information about heterocycles: pKas, synthesis, bond lengths and angles, more synthesis, and yet more synthesis and top drugs containing heterocycles from Prof. Phil Baran’s group. On the same site is Patrick Lam’s electrostatic potential maps
Synthesis Tools

Viruses
Virus World is a site curated by Juan Lama and is a great source for the latest on viruses including the recent COVID-19 outbreak caused by the SARS-CoV-2 virus. You can view a time lapse of the virus spread as well as mutation here.

Antibiotics and Infection
A one page backgrounder on resistant antibiotics from the CDC
Global infections by the numbers is a great short perspective on the issue from Scientific American
Causes of Death
While cardiovascular diseases are the predominant cause of death worldwide, infectious diseases combined are the next leading cause
