Daylight saving time means we change the clocks twice a year, and the world has over 30 different time zones. Some countries span multiple different time zones, while the likes of China and India choose to have just one time zone despite the huge differences in real time from east to west. Time influences almost every aspect of our lives – yet we barely ever stop to think about what time means exactly. Studies show the Daylight Savings Time leads to spikes in heart attacks and traffic accidents, while reduced sleep due changing times is linked to increased levels of obesity. So, why do we even bother? That's the argument of some scientists, who believe the whole world should switch to Coordinated Universal Time (UTC), which is already used in aviation and in space. In this video we ask, what if we abolished time zones (and clock changes) forever?

We need a coronavirus vaccine to beat the pandemic, but that's a problem. Why? Because making a Covid-19 vaccine that works (and is safe) will take a long time. Even the most hopeful estimates suggest it could take a year, but some believe we may have to wait until the end of 2021 to have a working cure, and that's before we tackle the problem of immunising the whole world. In this video we explore the challenges facing those looking to create a coronavirus vaccine, how human trials work and explain why developing a cure for coronavirus will take such a long time.

Plenty of films and movie franchises hide easter eggs, but Pixar takes it to another level. Pixar's Jonas Rivera reveals all of the secret references to Pixar movies hidden throughout their films.
