On June 30 2015 at 23:59:59 UTC (19:59:59 EDT), artist Sara Morawetz was standing in the middle of New York’s Times Square with a pair of cymbals. As the clock ticked to the next second, she struck the cymbals together.
This simple performance, titled 61/60, sought to highlight the strange blip of time where the clock read 23:59:60 UTC (Coordinated Universal Time), instead of 00:00:00 UTC.
Since 1972, extra seconds, known as leap seconds, have been added to clock time whenever our slightly wobbly Earth…

Completing value-added tax (VAT) returns takes time, and waiting for a refund can tie up money a business needs to pay suppliers or invest.
The South African Revenue Service wants to ease both pressures while making it harder for businesses to under-report VAT. VAT-registered businesses already file returns electronically, reporting VAT on their sales and purchases. The revenue service checks supporting invoices after submission when it requests them.
VAT is a tax on most goods and services. VAT-registered businesses charge it on the goods and services they supply, deduct…

Some 23,000 years ago, during the coldest part of the last ice age, people walked across the muddy margins of an ancient lake in what is now White Sands national park, New Mexico.
The footprints they left behind have transformed our understanding of when people first reached the Americas. When we reported dates for the White Sands footprints in 2021, our findings were met with controversy. They placed people in North America thousands…

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…
