Episode 310

An ancient Egyptian's complete genome has been read for the first time. The DNA of a man who lived in Egypt over 4500 years ago offers a new window into the ancient society and hints at surprising genetic connections with Mesopotamia. Based on forensic analysis of the man's skeleton and preserved images of different Egyptian occupations, the researchers think his most likely occupation was a potter. The team discusses what the breakthrough means for our understanding of early Egypt and even for the origin of writing.

Wild orcas, or killer whales, have been seen giving gifts to humans - things like pieces of liver, rays and dead birds. This is the first time these apparent acts of altruism have been documented. Does this prove whales are capable of showing compassion or kindness?

Images beamed back from the New Horizons spacecraft, which has left the solar system, have enabled the first test of interstellar navigation. By measuring the distance between two stars that it snapped images of, astronomers have been able to pinpoint its location in the galaxy. And in other interstellar news, we also just spotted an object hurtling towards our solar system. Recently named ‘Atlas’, this object will be whizzing by in October, close enough for us to study.
