Why do dogs often look like their owners?

Do you really know? ·

2025/10/11

Numerous archaeological findings have suggested that dogs were the first animals to be domesticated by humans over 20,000 years ago. So it’s little surprise that in this day and age, 29% of UK adults own a dog. That’s according to 2023 data from vet charity PDSA. If you have a dog, you may have been told that you share physical characteristics with it, a sort of family resemblance if you like. Well, as it turns out, this popular belief might be more than just a myth. Is there any scientific

Why are so many people suffering from AI anxiety?

Do you really know? ·

2025/10/11

A Pew Research Center survey from August 2023 found that 52% of respondents were more concerned than excited about AI in daily life, compared with just 10% who felt the opposite. It’s not surprising really when you think about it; after all, things that we don’t understand tend to both fascinate and frighten in equal measure. It’s only very recently that AI has started becoming part of many people’s everyday lives, and it’s still hard to predict its full impact in the future. The growing unease

On September 6th, UN Secretary-General Antonio Guterres released a 96-word statement in which he referred to “climate breakdown” having begun. It was in response to a report from the World Meteorological Organization, which highlighted the impact of record-breaking heatwaves across the globe this summer. June, July, and August 2023 are the hottest three-month period ever recorded. The WMO says that the increasingly frequent and intense heatwaves we’re experiencing are causing air quality to

2025/10/10

For most 18-24 year olds, generative AI is already part of daily life. Research, emails, translations, summaries - AI is everywhere. Its possibilities feel endless, limited only by our imagination. But with that comes a growing skepticism, especially in schools and workplaces: “Was this really written by a person?” “Did ChatGPT write that assignment?” The good news is, there are clues that can tip you off. What are these clues? But are there tools to detect generated text? But how do these tools

Listen again to our episodes about sport! It's well known that we should all be doing half an hour of moderate physical activity every day.

Why do we blow out candles on birthdays?

2025/10/09

It’s a scene that plays out in millions of homes across the world every day. There’s a sense of anticipation as the lights go out, only for the room to be lit up by candles as a friend or family member brings in a yummy-looking birthday cake. Guests start singing more or less in unison, more in less in tune, depending on how much alcohol has been consumed, and the birthday girl or boy politely waits until they finish before blowing the candles out. When did the tradition start out? Why do we make

What is broken heart syndrome?

2025/10/09

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 several years later, towards the end of the decade. The name is Japanese because that’s where the first case

Over in the US, a 2022 YouGov poll revealed that half of Americans enjoy true crime content, with one in three consuming it weekly. True crime is a unique genre, and distinct from detective fiction or thrillers due to its

What is stealth wealth?

Do you really know? ·

2025/10/08

Stealth wealth or quiet luxury as it is sometimes known is the practice of concealing one's wealth or not flaunting one's money or possessions, but rather keeping them private and discreet. It’s the kind of luxury that keeps a low profile and doesn't try to stand out with big logos or loud statement pieces. But that does not mean people don’t know you are wealthy, at least some people do. Look at the successful show ‘Succession’ where the uber rich wear logo-free, exquisitely tailored clothes that

How many calories does having sex burn?

2025/10/08

Sex can certainly make us work up a sweat; but is it enough to cancel out that burger and fries you got from McDonald’s at lunchtime? Well if you were thinking about quitting the gym in favour of sex-ercise, you may want to reconsider. Sex doesn’t actually burn as many calories as you might think. How many are we talking then? Does the position make a difference? If it’s not that intense, then why do we sweat so much? Are there any health risks to sex, like with other forms of exercise?To listen

Why is the brain our biggest sex organ?

2025/10/08

The brain plays a central role in desire, arousal, and sexual pleasure, but we don’t always realize just how much it influences our sex lives. While hormones and physical attraction are important, it’s the brain that processes emotions, triggers pleasure, and coordinates physical responses. According to neuroscientists, every part of the brain is involved in sexuality. The hypothalamus regulates hormones, the amygdala processes emotions, and the prefrontal cortex influences decision-making and

Everybody loves a rags-to-riches story, but the reality is social mobility is far from easy. Class-passers are those who manage to successfully improve their status and navigate their new life as part of a higher socioeconomic group. To understand class-passing, let’s first discuss the idea of social classes. Within our societies, people are divided according to factors like their family background, education, wealth, occupation and income. Most commonly these categories are described as the lower,

How can you tell if you’re stingy?

Do you really know? ·

2025/10/07

If there’s one trait nobody wants to claim, it’s stinginess. But being stingy isn’t about how much money you have. Take Ingvar Kamprad, the founder of IKEA—despite his fortune, he lived modestly and even shopped at flea markets. For him, frugality was a habit, not an obsession. But when caution with money turns into an all-consuming need to save at all costs, it can impact not just your finances, but also your relationships. Stingy people rarely see themselves that way. They often think they’re

Is holding back a sneeze dangerous?

Do you really know? ·

2025/10/06

Whether it's a matter of courtesy or preventing the spread of germs, it's not uncommon for people to hold back a sneeze. When this happens, the intercostal muscles contract strongly, but without the release of air if the nose is pinched or the mouth is closed. However, sneezing is a natural bodily reflex designed to expel dust, microbes, or any other irritating substances from the nasal cavity. Our respiratory system comes equipped with a filter lining the airways. Dust and allergens, for instance,

What is flexitarianism? Thanks for asking! Flexitarianism is a portmanteau word combining flexible and vegetarianism. It’s a mostly vegetarian way of eating which nevertheless allows for occasional meat dishes. The aim is to reduce red meat and animal protein consumption, replacing them with high-protein plant foods.This type of diet is becoming increasingly common, and the word flexitarian was added to the Merriam-Webster's Collegiate Dictionary in 2012.

How can I meditate without meditating?

Meditation is often sighted as a great way to relax, reduce stress and help us focus, but it can be difficult for lots of people to do in the traditional sense. However, meditation can be achieved without ever sitting down cross legged and focusing on your breathing. “The whole idea with mindfulness is training your brain, you can do this just as well by being intentionally mindful throughout the day.

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 were writing about female ejaculation and popularised Grafenberg’s findings in a book. Gräfenberg attributed

When we think of those who have high blood sugar, we tend to think of people with diabetes, as they often have to monitor their levels and sometimes undergo insulin treatment. But actually everybody can have blood sugar spikes, and many of us do without even realising. These occur when a simple sugar called glucose builds up in the blood. This is known as hyperglycemia. High blood sugar can make your mouth dry, make you feel thirsty, give you blurred vision and make you need to pee

Do men really have a better sense of direction than...

Do you really know? ·

2025/10/05

Some theories in evolutionary psychology propose that men are better at spatial navigation than women due to evolutionary factors. In prehistoric times, men, as hunters, traversed long distances, while women stayed closer to the home. This difference supposedly led to natural selection favouring genes in men associated with better spatial navigation skills. However, these theories have been widely challenged, in particular by British philosopher Cordelia Fine. Back in 2010 she published a book
