- Best fact: Insects can fly up to 3.25km above sea level, at least.
Alpine bumblebees have been found living as high up as 3.25km above sea level and could even fly in lab conditions that replicate the air density and oxygen levels at 9km – that's just higher than Mount Everest.
- Amazing Fact: Deaf people are known to use sign language in their sleep.
A case study of a 71-year-old man with rapid eye movement disorder and a severe hearing impairment showed him using fluent sign language in his sleep, with researchers able to get an idea of what he was dreaming about thanks to those signs.
- Best fact: LEGO bricks withstand compression better than concrete.
An ordinary plastic LEGO brick is able to support the weight of 375,000 other bricks before it fails. This, theoretically, would let you build a tower nearing 3.5km in height. Scaling this up to house-size bricks, however, would cost far too much.
- Amazing Fact: You remember more dreams when you sleep badly.
Research suggests that if you sleep badly and wake up multiple times throughout the night you will be more likely to recall the content of any dreams you had. You are also more likely to remember a dream when woken from one.
- Amazing Fact 🥰: The biggest butterfly in the world has a 31cm wingspan.
It belongs to the Queen Alexandra's Birdwing butterfly, which you can find in the forests of the Oro Province, in the east of Papua New Guinea.
- Best fact ❤️: A rainbow on Venus is called a glory.
Appearing as a series of coloured concentric rings, these are caused by the interference of light waves within droplets, rather than the reflection, refraction and dispersion of light that makes a rainbow.
- Amazing Fact: You can smell ants.
Many species of ants release strong-smelling chemicals when they’re angry, threatened or being squished. Trap-jaw ants release a chocolatey smell when annoyed, while citronella ants earn their name from the lemony odour they give off.

- Amazing Fact 🥰: There’s a planet mostly made from diamond.
Called 55 Cancri e, it's around twice the size of Earth and some 40 light-years away from us within the Cancer constellation.
- Fact: You travel 2.5 million km a day around the Sun without realising.
The Earth’s orbit travels around 2.5 million kilometres with respect to the Sun’s centre, and around 19 million km with respect to the centre of the Milky Way.
- Fact ❤️: Starfish don’t have bodies.
Along with other echinoderms (think sea urchins and sand dollars), their entire bodies are technically classed as heads.
- Fact❤️: You can be heavily pregnant and not realise.
Cryptic pregnancies aren’t that uncommon, with 1 in 500 not recognised until at least halfway through and 1 in 2,500 not known until labour starts.
- Best Fact 🥰: You can yo-yo in space.
In 2012, NASA astronaut Don Pettit took a yo-yo on board the International Space Station and demonstrated several tricks. It works because a yo-yo mainly relies on the laws of conservation of angular momentum to perform tricks, which, provided you keep the string taut, apply in microgravity too.
- Amazing Fact 🥰: The Moon looks upside down in the Southern Hemisphere.
Compared to the Northern Hemisphere, anyway. This means that the ‘Man in the Moon’ is upside down in the Southern Hemisphere and looks more like a rabbit.
- Best fact ❤️: Hippos can’t swim.
Hippos really do have big bones, so big and dense, in fact, that they’re barely buoyant at all. They don’t swim and instead perform a slow-motion gallop on the riverbed or on the sea floor. In fact, hippos can even sleep underwater, thanks to a built-in reflex that allows them to bob up, take a breath, and sink back down without waking.
- Amazing Fact 🥰:Finland is the happiest country on Earth.
According to the World Happiness Report, it has been for six years in a row. It’s not really surprising, given that Finland is the home of Santa Claus, reindeer and one sauna for every 1.59 people.

- The T.rex likely had feathers.
Scientists in China discovered Early Cretaceous period tyrannosaur skeletons that were covered in feathers. If the ancestors of the T. rex had feathers, the T. rex probably did, too.
- Fact: Ants don’t have lungs.
They instead breathe through spiracles, nine or ten tiny openings, depending on the species
- Chainsaws were first invented for childbirth.
It was developed in Scotland in the late 18th Century to help aid and speed up the process of symphysiotomy (widening the pubic cartilage) and removal of disease-laden bone during childbirth. It wasn’t until the start of the 20th Century that we started using chainsaws for woodchopping.
- You can actually die laughing.
And a number of people have, typically due to intense laughter causing a heart attack or suffocation. Comedy shows should come with a warning.
- Amazing Fact: Earth’s poles are moving.
This magnetic reversal of the North and South Pole has happened 171 times in the past 71 million years. We’re overdue a flip. It could come soon, as the North Pole is moving at around 55 kilometres per year, an increase over the 15km per year up until 1990.
- Fact: Comets smell like rotten eggs.
A comet smells like rotten eggs, urine, burning matches, and… almonds. Traces of hydrogen sulphide, ammonia, sulphur dioxide, and hydrogen cyanide were all found in the makeup of the comet 67P/Churyumove-Gerasimenko. Promotional postcards were even commissioned in 2016 carrying the pungent scent of a comet.
- Fact: Most maps of the world are wrong. On most maps, the Mercator projection – first developed in 1569 – is still used.
This method is wildly inaccurate and makes Alaska appear as large as Brazil and Greenland 14 times larger than it actually is. For a map to be completely accurate, it would need to be life-size and round, not flat.
- Amazing: Octopuses don’t actually have tentacles.
They have eight limbs, but they're arms (for most species). Technically, when talking about cephalopods (octopuses, squids etc), scientists define tentacles as limbs with suckers at their end. Octopus arms have suckers down most of their length.
- Best fact: Our solar system has a wall.
The heliopause – the region of space in which solar wind isn’t hot enough to push back the wind of particles coming from distant stars – is often considered the “boundary wall” of the Solar System and interstellar space.
- Amazing Fact 🥰: The Sun makes a sound but we can't hear it.
In the form of pressure waves, the Sun does make a sound. The wavelength of the pressure waves from the Sun is measured in hundreds of miles, however, meaning they are far beyond the range of human hearing.
- Best Fact: The world’s oldest cat lived to 38 years and three days old.
Creme Puff was the oldest cat to ever live.
- Best fact: The world’s oldest dog lived to 29.5 years old.
While the median age a dog reaches tends to be about 10-15 years, one Australian cattle dog, ‘Bluey’, survived to the ripe old age of 29.5.
- Amazing Fact 🥰:Wearing a tie can reduce blood flow to the brain by 7.5 per cent.
A study in 2018 found that wearing a necktie can reduce the blood flow to your brain by up to 7.5 per cent, which can make you feel dizzy, nauseous, and cause headaches. They can also increase the pressure in your eyes if on too tight and are great at carrying germs.
- Amazing Fact: All the world’s bacteria stacked on top of each other would stretch for 10 billion light-years.
Together, Earth's 0.001mm-long microbes could wrap around the Milky Way over 20,000 times.
- Amazing Fact: A chicken once lived for 18 months without a head.
Mike the chicken's incredible feat was recorded back in the 1940s in the USA. He survived as his jugular vein and most of his brainstem were left mostly intact, ensuring just enough brain function remained for survival. In the majority of cases, a headless chicken dies in a matter of minutes.
- Amazing Fact: Water might not be wet.
This is because most scientists define wetness as a liquid’s ability to maintain contact with a solid surface, meaning that water itself is not wet, but can make other objects wet.
- Fact: Animals can experience time differently from humans.
To smaller animals, the world around them moves more slowly compared to humans. Salamanders and lizards, for example, experience time more slowly than cats and dogs. This is because the perception of time depends on how quickly the brain can process incoming information.

- FACT: The largest piece of fossilised dinosaur poo discovered is over 30cm long and over two litres in volume.
Believed to be a Tyrannosaurus rex turd, the fossilised dung (also named a 'coprolite') is helping scientists better understand what the dinosaur ate.
- FACT: Your brain is constantly eating itself.
This process is called phagocytosis, where cells envelop and consume smaller cells or molecules to remove them from the system. Don’t worry! Phagocytosis isn't harmful, but actually helps preserve your grey matter.
- FACT: Identical twins don’t have the same fingerprints.
You can’t blame your crimes on your twin, after all. This is because environmental factors during development in the womb (umbilical cord length, position in the womb, and the rate of finger growth) impact your fingerprint.
- BEST FACT: Giraffes are 30 times more likely to get hit by lightning than people.
True, there are only five well-documented fatal lightning strikes on giraffes between 1996 and 2010. But due to the population of the species being just 140,000 during this time, it makes for about 0.003 lightning deaths per thousand giraffes each year. This is 30 times the equivalent fatality rate for humans.
- BEST FACT: A cloud weighs around a million tonnes.
A cloud typically has a volume of around 1km3 and a density of around 1.003kg per m3 – that's a density that’s around 0.4 per cent lower than the air surrounding it (this is how they are able to float).
- Good Morning Phaver frens
- Wish you a happy new year to all phaver frens
- FACT: Dead skin cells are a main ingredient in household dust
Here’s an interesting science fact for you: According to researchers at Imperial College London, humans shed around 200 million skin cells each hour—and they have to go somewhere when we’re indoors. If the idea of skin dust isn’t sitting well with you, you should know that a report from the American Chemical Society found that a skin oil called squalene naturally helps reduce indoor ozone levels by up to 15 percent.

- FACT: Wearing headphones for just an hour will increase the bacteria in your ear by 700 times
You cover your ears from the natural air when you wear headphones which increases the production of bacteria by 700% in 1 hour. Your eardrum cannot bear influx of bacteria in that much quantity so it starts to react by paining or hearing loss in long term.
- FACT: All polar bears are left handed.
No, this is a common misconception that polar bears are left-handed. But the research shows that both the paws are used equally. You can say that they are ambidextrous.
- FACT: "I Am" is the shortest complete sentence in the English language.
True, to make a sentence in English, it should both include a subject and predicate. In the sentence, ‘I am’, ‘I’ is subject and ‘am’ is a predicate and also expresses a complete thought. Thus, ‘I am’ is the shortest sentence in English.
- Wish you a happy morning. This is my sunflower plant flowering 1st time🥰🥰🥰
- Fact: People say "Bless you" when you sneeze because when you sneeze, your heart stops for a millisecond.
Your heart doesn’t stop completely but, it may slow down or skip a beat. But it has nothing to worry about.
- FACT: Allodoxaphobia is the fear of other people's opinions.
It's a rare social phobia that's characterised by an irrational and overwhelming fear of what other people think.
