Interview with ESA chief Josef Aschbacher
Shaping an ambitious and steady space agenda for Europe requires not only diplomatic aplomb but also a firm grounding in science and engineering. Indeed, those attributes are must-haves in working with the 22 member states of the European Space Agency (ESA). Josef Aschbacher is ESA’s director general, taking on that role in March 2021. He […]
Why can’t we throw all our trash into a volcano and burn it up?
New England stone walls lie at the intersection of history, archaeology, ecology and geoscience, and deserve a science of their own
The abandoned fieldstone walls of New England are every bit as iconic to the region as lobster pots, town greens, sap buckets and fall foliage. They seem to be everywhere – a latticework of dry, lichen-crusted stone ridges separating a patchwork of otherwise moist soils. Stone walls can be found here and there in other […]
