Everything we see, from galaxies to capybaras, is made of matter. But matter has a mirrored version of itself known as antimatter.

We live in a society that idolizes youth for sure, but also with age comes wisdom. However, aging is not all it’s cracked up to be. Could we keep getting older without the drawbacks of being old?

In this episode, host Dr Alfredo Carpineti is joined by Dr Andrew Steele, author of Ageless: The New Science of Getting Older Without Getting Old, to talk about the medical fight against old age at a cellular level and whether humans could

Everything we see and interact with, regular matter, is only a small fraction of what the universe contains. In fact, the vast majority of the universe is invisible to us. We've named these mysterious components dark matter and dark energy, but our understanding of them – and if they even exist – remains lacking. To unravel more of this mystery, Dr Alfredo Carpineti sat down with Dr Mandeep Gill from the Dark Energy Survey collaboration to ask: Will the new generation of upcoming observatories help
