[RERUN] What is Starlink? May 12, 2022

Show notes

On April 25th, Elon Musk struck a deal to buy Twitter for $44 billion.

What is Starlink?

While the Space Race makes us think back to the 20th century, some billionaires are dreaming of ruling space in 2020. In particular Elon Musk, the CEO of Tesla, who’s planning to send tens of thousands of satellites into orbit in coming years. The name of the project is Starlink and the goal is to deliver high-speed broadband access across the globe. Behind Starlink is the private company SpaceX, which Elon Musk founded in 2002. Earlier this year, it became the first private company to send astronauts into space. Musk has long held the ambition of colonizing the planet Mars, which remains a future objective for SpaceX. Since 2015, the company has been developing the Starlink megaconstellation of satellites. The stated aim is bold: providing high-speed internet access anywhere on earth. We’re talking at sea, in the middle of the desert or the depths of the countryside.

Doesn’t satellite internet access already exist?

Existing satellites giving internet access are in geostationary orbit and the technology only allows a limited number of users to access it. Latency times are also high, due to the 20,000 mile distance between the satellites and us on Earth. Starlink, on the other hand, sends satellites into Low Earth orbit at 550 miles. Latency will be reduced, and as the satellites will orbit more quickly, they will be able to cover the whole of the planet. Starlink has been authorised to send 12,000 satellites into space. To put that into perspective, Earth currently has just 2,200 artificial satellites.There are already 600 Starlink satellites orbiting, with the first launch mission dating back to February 2018. Service is set to be available in North America by the end of the year, with “near global coverage of the populated world” promised for 2021.

What about 5G? Are there environmental risks in sending all these satellites into orbit? In under 3 minutes, we answer your questions!

What is de-extinction? May 10, 2022

Show notes

What is de-extinction?

The process of de-extinction is all about bringing extinct species back to life. It became known in the 2010s, thanks to an ambitious plan from American geneticist George Church, who dreamed of resurrecting the woolly mammoth, an animal which has been extinct for 3700 years. Fast forward to the 2020s and Church’s bioscience startup Colossal is now eding closer towards making that a reality. As of March 2022, Colossal announced that it had raised a total of $75M for the project.

Is it really possible to revive extinct animal species? Why would we want to bring extinct species back to life? How is the idea of de-extinction being received by the scientific community? In under 3 minutes, we answer your questions!

[RERUN] What is negationism? May 10, 2022

Show notes

What is negationism?

Historical negationism refers to the practice of manipulating historical records to deny that certain events happened, or distort the narrative around them.

The term is relatively recent, having been coined by French historian Henry Rousso in 1987, relating to Holocaust Denial. Six million Jews were murdered by the Nazi regime during the Second World War.

Holocaust denial is certainly one of the most well-known and common examples of negationism. But similar distortion strategies have been seen relating to other genocides and war crimes across the world.

Negationism is a crime in some countries like Germany, while elsewhere the approach is more cautious, due to questions about freedom of speech. Other laws can apply to negationist statements, if they are also of a hateful or discriminatory nature.

So what exactly does negationism look like? In under 3 minutes, we answer your questions!

What are happy hormones? May 09, 2022

Show notes

What are happy hormones?

A recent scientific brief from the World Health Organisation, explained that anxiety and depression had increased by 25% worldwide over the first year of the Covid 19 pandemic. The massive rise was mostly down to social isolation and multiple stress factors like fear of infection and financial worries. It’s important to know that we can actually control our mood to some extent. It’s possible to boost our so-called happy hormones in natural ways, by opting for specific foods, activities and behaviours.

So how can we stimulate the production of these hormones and neurotransmitters? Why do they say that oxytocin is the love hormone? In under 3 minutes, we answer your questions!

[SCREEN FREE WEEK] What is a sedentary lifestyle? May 08, 2022

Show notes

From 2nd to 8th May 2022, it's time to unplug for the annual Screen Free Week celebration. All around the world, people are encouraged to limit their screen time and turn their devices off in favour of other activities. Do You Really Know is rerunning a series of episodes dedicated to the digital world and its impact on our lives.

What is a sedentary lifestyle?

A sedentary lifestyle is one which involves little or no physical activity. It’s one of the major global health issues of the 21st century, as it is an underlying cause of death, disease and disability. It’s estimated that each year over 300,000 premature deaths are caused by obesity and sedentary lifestyles, just in the United States.

Screen time spent in front of a computer or TV is often a good indicator of how inactive a person is. When we sit down, our muscles don’t perform the important contractions our bodies need to clear glucose and fats from our blood. This in turn increases the risk of diabetes or heart problems.

Why are we living a sedentary lifestyle ? In under 3 minutes, we answer your questions !

What is erectile dysfunction? May 07, 2022

What is erectile dysfunction?

As many as six in ten men have experienced erection problems over the course of their life. And that proportion has been on the rise in the last fifteen years, according to a study released by IFOP in April 2019. It’s also known as impotence, and is a big health taboo among men. Erectile dysfunction is often linked to cardiovascular risk factors, so it’s important to consult a doctor if affected. Furthermore, it can impact relationships, sometimes due to misunderstandings about the cause of the problem. The good news is it can be addressed with lifestyle changes, as we’ll discuss in a minute.

How do erections actually work? So why might that mechanism not work in some people? What about psychological or emotional factors? In under 3 minutes, we answer your questions!
