What is terraforming? Thanks for asking! If you’re a fan of sci-fi, the idea of terraformation should be familiar. It refers to all the techniques and technologies which aim to transform the surface of a planet, making it suitable for human inhabitation. Basically, it means making a planet similar to Earth. To make a Hollywood comparison, that’s exactly the purpose of the Weyland-Yutani company in...

What is the Pegasus Project? Thanks for asking! Ever since the Snowden case of 2013, the world has gotten used to the idea that states use surveillance to monitor people’s activity. All the same, the fallout from the Pegasus Project revelations of recent weeks has been huge, making it a highly significant cyber espionage scandal. The initiative was coordinated by French media nonprofit organizatio...

No one's proud of being unfaithful, but what if some people’s cheating was actually caused by genetics, rather than selfishness? That might sound like a convenient excuse, but actually there could be some scientific basis behind it. In 2022 researchers at the University of Queensland in Australia analysed the DNA of over 7,300 twins aged between 18 and 49, all of whom had been in relationships for...

What is geophony? Thanks for asking! Taking its name from the Greek prefix geo, as in the earth and phony as in sound, geophony could be most simply described as part of Planet Earth’s music. It’s a component of the soundscape that has surrounded us humans ever since we have been present on Earth.  We owe the concept to experts like Canadian composer and environmentalist Raymond Murray Schafe...

The idea of a broken heart may make you think of a cartoon, an emoji or a bad break-up from your past. But broken heart syndrome is a real physical condition, which is also known as Tako-tsubo. Good guess but just wide of the mark. Tako-tsubo syndrome was described for the first time in Japan, at the start of the 1990s. Researchers in the western world didn’t acknowledge the condition until s...

Ah, the G-spot... An often cited but frequently elusive erogenous zone which has a reputation of being able to unlock intense female orgasms if you know how to stimulate it the right way.  The G-spot was first discovered by German gynecologist Ernst Gräfenberg - hence the G part of the name - back in 1950. But the term was only coined in his honour in the 1980s, by a group of researchers who...

Because moving and doing regular physical activity is important for our physical and mental health! Listen again to our episodes about sport! After an intense and sweaty workout, the first thing most of us want to do is jump into the shower to relax our muscles and wash off the sweat. However, that’s not actually the best idea. Showering too soon after a workout can have harmful effects on our hea...

With the summer holiday season drawing to a close, many university students are preparing to leave home for the first time and head to campus accommodation. While they’re enjoying freshers week, chances are their parents may be finding it unsettling that their child is no longer present at home. That’s even more likely when it’s their last child who’s just left home. This form of grief is kno...

In this day and age, it’s common to feel stressed every day, even right through to the evening. Have you ever struggled to lower your stress levels when it comes to bedtime, and taken a long while to fall asleep as a result? The worry of not getting enough sleep then just gets you even more frustrated; it’s a vicious circle. If you’re falling victim to anxiety and fatigue for that reason, it’s tim...

Are you someone who thrives on making decisions at work, or do you prefer to take a back seat and let others have the final say? Decisions can be a source of anxiety, even for those who generally like making them. That's especially true when the sheer quantity of decisions to be made adds up, and you've got a limited amount of time in which to make them. That happens frequently to people working i...

What are Fan Tokens? Thanks for asking! Even if you’re not a football fan, you can’t have missed the news of Lionel Messi’s recent transfer to Paris Saint Germain in mid-August. But you may not have heard details of the star’s €30M sign-on package at PSG, a significant proportion of which was paid in the club’s Fan Token cryptocurrency. The move led to a spike in PSG trading, with the token value...

The UN’s COP26 summit is due to start this Sunday, and it’s pretty clear to most of us that climate change is the most serious threat to our health. Of course it’s a physical threat, especially to the vulnerable, due to extreme weather events like heatwaves, storms and fires, which are increasingly frequent and intense.  But we mustn’t neglect the mental impact, as fear of the future is eatin...

What is mucosal immunity? Thanks for asking!  It was announced last week that Covid booster vaccines would soon be available to millions of people across the UK, including all over 50s and other people with underlying health conditions.   In the meantime, new ways to combat the virus are emerging, specifically that of an nasal spray vaccine designed to boost mucosal immunity. Regula...

In June it emerged that Greek police had acquired two long range acoustic devices, designed to discourage migrants from approaching the country's border with Turkey. At the size of a small TV, the cannons don’t look particularly threatening, but are capable of emitting powerful sound waves as loud as a jet plane. An LRAD is an example of a sonic weapon, which is an umbrella term used to cover the...

Speculative science fiction really is a genre of its own. Some people love it, others find it pointless, but you can’t deny the mental gymnastics involved in imagining the future of our societies, especially when some of those predictions turn out to be right.  In that field, there are a few writers who stand out above the rest: George Orwell, Aldous Huxley, and, perhaps most famously, Isaac...

November is synonymous with Black Friday, great deals but what cost? Over consumption is endangering our already fragile planet. Is it time to change our ways? This week Do You Really Know is highlighting concepts and initiatives about reducing our consumption. All week long we’ll be discussing anticonsumerist trends as an alternative to Black Friday. Zero waste is a good example of one that has b...

Over on TikTok, the #idontchaseiattract hashtag is nearing in on 20,000 publications at the time of recording. It really took off in late 2023, especially after Kendall Jenner said the following in an interview with Enews.  Behind the simple statement are young women advocating that with enough belief, you can manifest whatever you want in life. You might have also heard of "Lucky girl syndro...

For a number of years now, our smartphones have played a central role in many aspects of our lives, from work to personal relationships to entertainment. There’s a close and sometimes addictive connection.  Just think of doomscrolling for example, which is a phenomenon we’ve discussed in the past on Do You Really Know. It’s a form of behaviour which sees us compulsively scrolling through...

There’s a lot of popular ideas out there about body hair removal. Shave too much and the hair becomes thicker. Wax, and it will gradually start thinning out. It can be hard to know who or what to believe. Both women and men increasingly spend a lot of their time and money removing body hair, even though it acts as a barrier to bacteria, and sexually transmitted diseases in the case of pubic hair....

According to the Office for National Statistics, the number of births in the UK continues to fall. Experts are even talking about a “baby bust”, the opposite of the “baby boom”, to describe these statistics, which have reached the lowest level since records began in 1938. One explanation for this could be that people are having children later than previous generations, leaving them with a reduced...

What are the Puppy Blues? You’ve no doubt already heard of the baby blues, a nice-sounding euphemism for the rather unpleasant postpartum depression. Well, some new pet owners have started talking of puppy blues in the same way, to describe the sadness they sometimes feel after adopting a new furry companion. The puppy blues might be behind increased animal abandonment rates during the summer. Add...

This summer, relax and learn with Do You Really Know! It's time to learn all about the concepts, words and expressions that surround the summer season! What is a heat dome? The Pacific north-west is typically a mild region when it comes to weather. But in late June, Western Canada experienced record temperatures, with the province of British Columbia hit particularly hard. Temperatures are usually...

What is the global bike shortage? Thanks for asking! Cycling has enjoyed a huge boom since the start of the Covid-19 pandemic. Local authorities have increased efforts to prioritise cyclists over drivers, creating new bike lanes and making other investments in this form of transport. However, a shortage of bikes has been affecting the whole world since 2020. This supply chain nightmare is still go...

Amazon founder Jeff Bezos stepped down from his position as the company’s CEO to focus on other projects. He’ll remain executive chairman at Amazon but now wants to dedicate more time to other projects, including his space tourism company Blue Origin.  Following that surprise announcement, British business magnate Richard Branson also declared his desire to go into space with his company Virg...

What are you most attracted to when looking for someone to date? Social status? A sense of humour? Good looks? Those are all positive traits for sure, but for sapioseuxals there’s one quality which trumps all others, and that’s intelligence. The word comes from the Latin word “sapien”, which means wise. Sapiosexuals don’t fall in love at first sight or even through an emotional spark. Rather, they...
