What to do when cutting emissions alone is no longer enough

Global emissions reach about 40 billion tons each year. Such a massive number can be hard to conceptualize, but chemical engineer Jennifer Wilcox offers some context: Approximately 10 billion of these come from the transportation ...

Electric solid propellant: Can it take the heat?

Electric solid propellants are being explored as a safer option for pyrotechnics, mining, and in-space propulsion because they only ignite with an electric current. But because all of these applications require high heat, ...

Heat wave signals the growth of a stellar embryo

An international research team with the Max Planck Institute for Astronomy (MPIA) participating has detected a propagating heat wave near a massive protostar. It confirms the scenario that such objects grow in bursts. This ...
