The coastline near the southern tip of Africa looked vastly different between about 400,000 years ago and 70,000 years ago, compared with today. At times it lay as much as 100km south of its present location, exposing the vast Palaeo-Agulhas Plain, which contained an extensive habitat for large mammals. At other times the sea level was briefly as much as 13 metres higher than today’s mean level.
Through our work as…

The drone has become the signature weapon of the Russo-Ukraine war. On any day in Ukraine, tens of thousands of drones are out hunting the battlefield for targets. These could be individual enemy soldiers or vehicles, or they could be larger targets such as depots, headquarters, bridges or power plants.
Yet, this drone war has been possible only because of a less obvious but equally vital technology. Elon Musk’s SpaceX…

The Earth got its Moon when a small planet collided with our planet more than four billion years ago. This impact hurled molten rock into space, which eventually coalesced to form the satellite we can see every night from across our planet.
But what of our neighbour, Mars? The red planet has two small, irregularly shaped moons called Phobos and Deimos. There are several theories on how these natural satellites formed, but no clear front-runner. Soon, a Japanese-led space mission called Martian Moons Exploration…

For more than 20 years, Canada’s Species at Risk Act (SARA) has protected wildlife that are at risk of being lost from Canadian lands and waters. Once a species is listed as extirpated, endangered or threatened under the act, it becomes illegal to kill, harm or capture it or damage its residences. Its critical habitat must also be protected, at least on federal land.
Nevertheless, these protections are routinely delayed for years. Our…
