Astronomers are worried by a satellite brighter than most stars
In this episode:00:45 A bright satellite is concerning researchersSatellites reflect sunlight down to Earth, and some do so with such intensity it risks obscuring astronomers' observations from ground-based telescopes. A paper in Nature suggests that the telecommunications satellite called BlueWalker 3 at times outshines most stars visible from Earth. Astronomers worry about the increasing number of such bright satellites making astronomy more difficult, and so the team suggest that future launches should undergo impact assessments.Research article: Nandakumar et al.Nature News: Huge new satellite outshines nearly every st...

How mummies were prepared: Ancient Egyptian pots spill secrets
In this episode:00:47 Chemical analysis of ancient embalming materialsMummification was a significant part of ancient Egyptian culture but, despite decades of research, much is unknown about the substances and methods used during the process. Now a team have analysed the contents of ceramic vessels uncovered in an embalming workshop that dates back to around 600 BC. The results reveal that some substances assumed to be a single thing were actually mixtures, while some came from far outside Egypt, providing a clearer picture of ancient mummification practices.Research article: Rageot et al.News and Views: Recipes for ancien...

Using quantum tools to track dark matter, why rabies remains, and a book series on science and food
On this week’s show: How physicists are using quantum sensors to suss out dark matter, how rabies thwarts canine vaccination campaigns, and a kickoff for our new series with authors of books on food, land management, and nutrition science
Dark matter hunters have turned to quantum sensors to find elusive subatomic particles that may exist outside physicists’ standard model. Adrian Cho, a staff writer for Science, joins host Sarah Crespi to give a tour of the latest dark matter particle candidates—and the traps that physicists are setting for them.
Next, we hear from Katie Hampson, a professor in the Ins...
