Can plants communicate with one another? Jul 03, 2026

Show notes

You might think that plants are silent and passive, but recent studies have shown that they can actually make sounds and send signals to each other, especially when they are stressed or under attack.

Researchers at Tel Aviv University recently released their findings from a six-year experiment, which saw them record sounds emitted by certain plants. We’ve actually known for over 10 years now that plants emit vibrations, but it’s the first time that sounds have been detected, meaning it’s a groundbreaking find.

Why don’t we hear plant noise then? Why would plants need to communicate with each other? What impact could this discovery have on agriculture? In under 3 minutes, we answer your questions!

What are the alternatives to air conditioning? Jul 02, 2026

Show notes

As summers get hotter, more and more people are turning to air conditioning to cool down buildings and vehicles. Not only does it make us more comfortable and productive, and can also save lives; after all, in the US, extreme heat is the single deadliest form of extreme weather.

But air conditioning has some drawbacks, such as high energy consumption, greenhouse gas emissions, and indoor air pollution. Air conditioning can also make us less tolerant of heat.

Who has access to air conditioning? What are the impacts of air conditioning on the environment? What are some alternatives to air conditioning? In under 3 minutes, we answer your questions!

Is remote work here to stay? Jul 02, 2026

Show notes

COVID-19 lockdowns led to the revolutionary rise of remote work. But while working remotely may have been a necessary adaptation made during an unprecedented global health crisis, many experts say that not only is remote work here to stay, it will even continue to increase as we head into 2023.

Employees save time and money by not having to commute, and they essentially have more control over their work environment, which can lead to increased creativity. With jobs becoming less location-specific, businesses can also benefit, one example being that they have a larger pool of talent to hire from.

What are the main benefits? Is going fully remote the best work model? What can we expect remote work to look like in the future? In under 3 minutes, we answer your questions !

Can I reuse sunscreen from one year to the next? Jul 02, 2026

Show notes

Sunscreen is essential when on holiday, and in the summer in general. But it doesn’t come cheap, and often the contents aren’t fully used by the time the holiday is over. It’s tempting to reuse bottles from one year to the next, to save money and reduce waste.

What many people don’t know though is whether sunscreen remains effective once it’s been opened, or whether using an out-of-date product is dangerous.

How can I tell if my sunscreen has expired? What are the risks of using out-of-date sunscreen? What steps should I take to stay safe? In under 3 minutes, we answer your questions!

What is cybersickness, the mysterious condition linked to screen use? Jul 01, 2026

Show notes

You may well have experienced motion sickness or travel sickness in the past. Well, cyber sickness is a modern ailment that follows a similar kind of logic, or rather the opposite logic. Instead of moving while feeling still, like when you’re on a boat or in a car, with cyber sickness you perceive movement while you’re actually still.

But the result is the same: your brain fails to adapt to this dissonance, and hence brings on nausea, dizziness, cold sweats, and other balance disorders. This can happen when using a computer, smartphone, or virtual reality headset.

What's the similarity with motion sickness ? Why doesn’t it affect all of us then? What can I do if I start feeling unwell in front of my laptop or smartphone screen then?In under 3 minutes, we answer your questions !

What is the Pygmalion effect? Jul 01, 2026

Show notes

Have you ever wondered how our expectations can impact the way we perceive and interact with others? Well, it’s actually been demonstrated that beliefs and attitudes can lead to outcomes that align with those beliefs, due to what’s known as the Pygmalion effect.

20th century American psychologist Robert Rosenthal coined the term in 1968. He had teamed up with San Francisco elementary school principal Lenore Jacobson to conduct a groundbreaking experiment. It showed that teacher behaviour and attitude could actually influence their students' achievements.

Where does the name come from? What did Rosenthal and Jacobson’s experiment consist of? In under 3 minutes, we answer your questions!

Are women really more emotional than men? Jul 01, 2026

Show notes

"Irrational”, “overdramatic”, “hysterical”, “sensitive” - if you’re a woman you have most likely been described using one of these words or similar in the past. That’s because there’s a common belief that women are more emotional than men, which still persists to this day.

It can sometimes be framed in a positive way, saying that women show more empathy. But all too often it’s used as a weapon to dismiss what a woman is saying.

Is there any scientific basis to such assumptions? What were the results then? How so? In under 3 minutes, we answer your questions!

How can I recognise a narcissistic pervert? Jun 30, 2026

Show notes

The concept of the narcissistic pervert has invaded our screens and magazines in recent years. It's used a lot, but sometimes wrongly or without full understanding.

So what is it really about? The term was first defined in 1986 by French psychoanalyst Paul-Claude Racamier. He said that narcissistic perverts have a prevailing need to boost their own self-esteem at the expense of others, and actually take pleasure from doing so.

What actually is a narcissistic pervert? Aren't we all a little like that? What makes narcissistic perverts different? Are narcissistic perverts dangerous to be around? In under 3 minutes, we answer your questions!

What is the Golem effect? Jun 30, 2026

Show notes

Not long ago we talked about the Pygmalion effect in an episode of Do You Really Know? Well today’s subject is pretty much the exact opposite! The Golem effect is the idea that negative words or assumptions can influence behaviours and transform those assumptions into reality. It’s another type of self-fulfilling prophecy, which sees lower expectations lead to poorer performance and behaviour in individuals.

And just like the Pygmalion effect, the term was also coined by Robert Rosenthal, this time in a 1982 paper after having conducted research along with Elisha Babad and Jacob Inbar. The name comes from Jewish folklore, and more specifically the tale of the Golem of Prague.

What are the main areas in which the Golem effect can be observed ? What about in relationships?How can we overcome the Golem effect? In under 3 minutes, we answer your questions !

Which five foods slow ageing? Jun 30, 2026

Show notes

Ageing is part of the natural cycle of life, and there’s no such thing as a miracle pill to prevent it. At least not yet ! Nevertheless, it is still possible to delay the effects of this process through a healthy lifestyle and good nutrition.

No doubt you’ve already heard of the benefits of regular physical activity, getting enough sleep and giving up cigarettes or alcohol. But generally speaking, you should prioritise foods that are rich in antioxidants. The term "antioxidants" includes certain vitamins, trace elements, and micronutrients found in large quantities in fruit and vegetables, for example.

What foods should we be focusing on ? Where can you find antioxidants in abundance ? What about drinks? In under 3 minutes, we answer your questions !
