Despite drastic reductions in lead poisoning since the 1970s, some children are still being exposed to lead from atypical sources, including cosmetics and folk remedies with often-unknown origins. Medical geologists are on the case.
(Older guy’s annual question) What’s the favorite hobby of people my age?
(early-career group’s annual answer) Travel? Golf?… Reading?… Bridge?… (old guy shakes his head, prompting increasingly sarcastic guesses) Bingo?… Naps?
(Older guy) No… the favorite hobby of people my age is getting together with each other and saying “The world used to be terrific but now it’s going to hell in a handbasket…”
(early-career group – laughter, flash of recognition; after all, they’ve all watched this scene play out at home, year after year – at the dinner table, while growing up; at family reunions; on holidays…)
(Older guy, continuing) …but the cure for that is hanging around you all! To do so is to realize that the future is in good hands.

An international team of astronomers using the NASA/ESA Hubble Space Telescope and the European Southern Observatory’s Very Large Telescope has made the most precise test of general relativity yet outside our Milky Way. The nearby galaxy ESO 325-G004 acts as a strong gravitational lens, distorting light from a distant galaxy behind it to create an Einstein ring around its centre. By comparing the mass of ESO 325-G004 with the curvature of space around it, the astronomers found that gravity on these astronomical length-scales behaves as predicted by general relativity.
