MIT physicists developed a way to probe inside an atom’s nucleus, using the atom’s own electrons as “messengers” within a molecule. They plan to map the distribution of forces inside a radium nucleus, which could help to explain why we see more matter than antimatter in the universe.
In the White Mountains of New Hampshire, the streams are telling us a story about forest recovery following acid rain and logging. According to a new study in the Proceedings of the National Academy of Sciences, long-term watershed chemistry reveals that recovering forests are mining rocks for nutrients. While this leads to improved pH in nearby streams, it further depletes soils, leaving forests less resilient to future pollution. The study team analyzed more than 60 years of data from the Hubbard Brook Experimental Forest, established by the US Forest Service in the 1950s for ecological and hydrologic research.
