Every tree, even an evergreen, can be an air quality monitor. That’s the conclusion of researchers who measured the magnetism of particulate matter on the needles of evergreen trees. That measurement, they found, correlated to general air quality, suggesting that analysis of the needles — a relatively simple and low-cost process — could provide a […]

How can conifers that are used, for example, as Christmas trees, keep their green needles over the boreal winter when most trees shed their leaves? Science has not provided a good answer to this question but now an international team of scientists has deciphered that a short-cut in the photosynthetic machinery allows the needles of […]
