Global Covid-19 Case Fatality Rates
This page is updated regularly as new information emerges. It sets out the current Case Fatality Rate (CFR) estimates, the country-specific issues affecting the CFR, and provides a current best estimate of the CFR, and more importantly, the Infection Fatality Rate (IFR).

Radioactive Waste Management
Nuclear waste is neither particularly hazardous nor hard to manage relative to other toxic industrial wastes. The amount of radioactive waste is very small relative to wastes produced by fossil fuel electricity generation. Safe methods for the final disposal of high-level radioactive waste are technically proven.

Study of 72,000 COVID-19 patients finds 2.3% death rate
Researchers from China's Center for Disease Control and Prevention today describe the clinical findings on more than 72,000 COVID-19 cases reported in mainland China, which reveal a case-fatality rate (CFR) of 2.3% and suggest most cases are mild, but the disease hits the elderly the hardest.

MIT-designed project achieves major advance toward fusion energy
For the first time, a large high-temperature superconducting electromagnet was ramped to a field strength of 20 tesla, the most powerful magnetic field of its kind ever created. The demonstration helps resolve the greatest uncertainty in the quest to build the first fusion power plant that can produce more energy than…
