A German start-up has secured initial funding to develop a revolutionary fusion energy machine that it hopes can provide a future source of abundant, emissions-free power. Proxima Fusion, incorporated in January, aims to build a complex device known as a stellarator and is the latest company to join the emerging fusion industry’s effort to generate electricity by fusing atoms. Although the amount of funding is small at only €7mn, it is significant as Proxima is the first fusion company to spin out of Germany’s revered Max Planck Institute for Plasma Physics. Little known outside the world of plasma physics, a stellarator is an alternative to the better-known tokamak device. The twisted structure of the stellarator is more complicated to design and build than a traditional tokamak but produces a more stable plasma that could enable scientists to sustain the fusion reaction for longer.

The awful truth remains: By 2019—that is, even before COVID—the Class of 1980’s death rates at age 39 were higher than their counterparts’ from the Classes of 1970 and 1960. At age 29, the Class of 1990’s death rates were indistinguishable from those of the Class of 1950. In Japan, the Class of 1990’s mortality rate at age 29 was over 80 percent lower than those of their “grandparents” from the Class of 1930. In the US, the corresponding differential was less than 8 percent. If we look carefully at Figure 2, we can see unwelcome “crossovers”—where death rates in adulthood exceeded those of earlier cohorts—for every US cohort from the Class of 1950 onward in the years after the Berlin Wall fell (1990 onward). This is what prolonged stagnation—at times, even reversal—in national health progress looks like.
