For 50 years air conditioning in commercial buildings has been set using the Standard 55 guidelines. But many workplaces aren't staffed solely with 40-year-old men dressed in 60s business suits, and that's left women out in the cold, as Dr Karl Kruszelnicki argues.

From the formation of Earth until now, many factors have contributed to its changing state. But humankind has been a major contributor in a relatively very small period of time, as Dr Karl Kruszelnicki argues.

Could lightning be used to power the planet instead of fossil fuels? Karl Kruszelnicki finds out.

It take a unique series of weather factors to create the awesome power of lightning but when it 'strikes' it comes to earth with 1000 times more energy that a household electrical system and with more heat than the sun but capturing this energy is difficult as Dr Karl Kruszelnicki explains.

As New Year's Eve ticked over to 2017, scientists added an extra second to atomic clocks to compensate for the Earth's variable rotation. But there are pros and cons to doing this, as Dr Karl Kruszelnicki explains.

We know that the rotation of the Earth is gradually slowing down. But what would happen if God, the devil or aliens suddenly and completely stopped our planet from rotating on its axis of spin? Luckily, thanks to improved knowledge about our planet, the geographers can now give us the answers.

There are many reasons animals of the same species congregate in groups. The collective intelligence of a flock helps protect and save energy, keep them on track when migrating and share food discoveries, as Dr Karl explains.

Being stuck in one spot, waiting for the full moon to pass and the perfect temperature to arrive, and your choice of mate left to the tide: when you're coral, reproduction is mind-boggling complicated, as Dr Karl Kruszelnicki explains

Coral polyps appear totally helpless at first. So how do they manage to survive, breed and form giant structures like the Great Barrier Reef?

If you've ever had a song stuck in your head you'll know it's annoying. But as Dr Karl Kruszelnicki explains, it might be an evolutionary way of keeping us alert to attack or stay focused during repetitive tasks.
