SoT 299: Ingesting Geese

Hosts: Ed Brown, Penny Dumsday, Lucas Randall

00:01:04 Vitamania is stronger than ever, with more than half of Americans and nearly a third of Australians regularly taking vitamin supplements. But a new study finds that most vitamin supplements have little or no benefit, and some can even be doing harm.

00:10:03 If there's life elsewhere in the universe, there's a good chance it's bacteria or something much like it. Now astrobiologists are pushing for more attention to be paid to extra-terrestrial viruses, as viruses are the most common form of "life" on Earth.

00:18:24 Europe's oldest tree has been dated, which is a bit more complicated than counting growth rings.

00:24:40 Australian magpies that live near airports seem to be less afraid of aeroplanes. Whether that's a good thing or a bad thing remains to be seen.

This episode contains traces of an ad for Flintstones Vitamins.
