What's The Fewest People That Could Repopulate Earth?

23 juil. 2026

If nuclear blasts, asteroids, or alien lasers killed off almost all humans on Earth, how many people would be needed to rebuild a genetically sustainable human population? LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Gene Pool: The total collection of different genes within a population. A larger gene pool means more genetic diversity. - Genetic Diversity: Having a wide variety of different genes within a population. - Inbreeding Depression: The reduced biological fitness caused by loss of genetic diversity as a result of inbreeding, or mating between closely related individuals within a species. - Recessive Genes: Genes that only cause a trait or disease when two copies are present (one from each parent).

How High Can Birds Fly?

19 juin 2026

Get started with Brilliant's tutor for free and get 20% off an annual subscription at https://brilliant.org/minuteearth In 1973, an airliner struck a bird called a Rüppell's griffon vulture – which, on its own, isn't that weird; planes hit birds pretty regularly during takeoffs and landings. But this collision happened at a cruising height of over 11,000 meters – WAY above the height at which most birds fly – which makes us wonder: what is the highest a bird can actually fly? LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Lift Coefficient: A dimensionless number that represents how effectively a wing generates lift based on its shape and angle. The higher the coefficient, the more lift produced. - Square Cube Law: A principle stating that as an object increases in size, its volume grows much faster than its surface area. This affects heat loss/gain and strength, impacting flight feasibility.

How To Kill A Volcano

28 mai 2026

Volcanoes are one of the most powerful forces on Earth; their lava can destroy cities and their ash clouds can blot out the sun. And there is basically nothing we can do to make sure a volcano will never erupt again – except wait for it to die. So while we wait, what is it, exactly, that kills a volcano? LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Conduit: A channel or passageway through which magma travels from a magma chamber to the surface. - Hotspot: A location on Earth's surface where molten rock rises from deep within the mantle, creating volcanoes independent of plate boundaries. - Plume: A column of rising, hot air or gas, often associated with volcanic activity or hot spots.

Why Don't Blue Whales Eat Fish?

Why Bees Mostly Ignore The Waggle Dance

15 avr. 2026

You've probably heard that bees use a complex series of movements – often called the "waggle dance" – to tell other worker bees where to find new sources of nectar…it’s a super clever and sophisticated system. But it turns out that bees almost never immediately jump up to follow the directions they just got, which, weirdly, is also super-clever and sophisticated.

Could This Thing *Really* Fly?

11 mars 2026

Help stop the worst parts of factory farming: https://www.farmkind.giving/minute-earth?promo=minute_earth The Quetzalcoatlus – one of the largest pterosaurs that ever lived – was able to fly even though it was the size of a giraffe! How on Earth did this giant manage to fly? LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Pterosaurs: are an extinct clade of flying reptiles in the order Pterosauria and are the earliest vertebrates known to have evolved powered flight. - Quetzalcoatlus: is a genus of azhdarchid pterosaur. Quetzalcoatlus northropi has gained fame as a candidate for the largest flying animal ever discovered. - Deltopectoral crest: is a forward directed bony flange on the upper part of the humerus. It provided insertion surfaces for muscles of the shoulder and chest. - Postcranial pneumaticity: is the presence of air-filled cavities inside bones of the body (everything except the skull) that are connected to the respiratory system. - Quad Launch (also Quadrupedal launch): is a takeoff method where an animal launches into the air using all four limbs—both the hind legs and the forelimbs.

LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Haplodiploidy: is a sex-determination system in which males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid. - Sex determination in honeybees: In honeybees, the drones (males) are entirely derived from the queen, their mother. The diploid queen has 32 chromosomes and the haploid drones have 16 chromosomes. Drones produce sperm cells that contain their entire genome, so the sperm are all genetically identical except for mutations. - Eusocial: showing an advanced level of social organization, in which a single female or caste produces offspring and nonreproductive individuals cooperate in caring for the young. - Fertilize: cause (an egg, female animal, or plant) to develop a new individual by introducing male reproductive material. - Genetics: the study of heredity and the variation of inherited characteristics. - Queen Bee: the single reproductive female in a hive or colony of honeybees. - Sterile: not able to produce children or young.

It turns out that most researchers now think that _Smilodon populator_ had a short tail rather than a long tail, but we didn’t catch that in time for the first poster print. We changed it for the video, and we’ll change it for future printings of the poster!

Why Don't Our Bones Keep Growing Forever?

31 oct. 2025

Download the Tab For Animals browser extension at https://tabforanimals.org/minuteearth2 Fish, amphibians, and reptiles –actually, almost all vertebrates– get bigger throughout their lives; they generally keep on growing until they die. Then, there are humans, who, by the age of 20 or so, just stop getting bigger… or at least taller. Why do we stop growing partway through life? LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Cartilage: firm, whitish, flexible connective tissue found in various forms in the larynx and respiratory tract, in structures such as the external ear, and in the articulating surfaces of joints. It is more widespread in the infant skeleton, being replaced by bone during growth. - Estrogen: any of a group of steroid hormones that regulate sexual development and function. - Growth plate: areas of cartilage located at the ends of long bones in children and adolescents. - Indeterminate growth: a biological process where an organism continues to grow throughout its life, rather than stopping at a genetically predetermined size.

Do Mushrooms Benefit from Being Hallucinogenic?

Nobody knows why some mushrooms are psychedelic. I mean, we know that they contain a compound called psilocybin, which messes with the brain chemistry of lots of animals, including humans.

How Deep Can Caves Get?

CORRECTION: As some of you have pointed out, at 2:12 the narration should say "diamond-mesh coated rebar" not "diamond-coated rebar." It sounds awesome, but it doesn't make sense to reinforce the walls of a gold mine with minerals more expensive (and brittle) than gold. Krubera Cave, one of our planet’s deepest known caves, extends 2200 meters into the earth – that’s a depth of nearly six Empire State Buildings. Or at least, that's as far down as humans have been able to explore; there might be other undiscovered chambers that go down even farther. But the cave can't be that much deeper, because there's a limit – actually, three limits – to how deep caves on Earth can get. LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Karst: landscape underlain by limestone which has been eroded by dissolution, producing ridges, towers, fissures, sinkholes and other characteristic landforms. - Solutional cave: a cave usually formed in a soluble rock like limestone - Water table: the upper surface of the saturated zone underground, where all the pores and cracks in soil and rock are completely filled with water.

Discover who you are with MyHeritage. Get a 14-day free trial here: https://bit.ly/MinuteEarth2 Venomous snakes kill nearly 100,000 people a year. Which is weird, because we have a pretty effective treatment for venomous snake bites; it’s actually been around for more than a hundred years. So why are so many people still dying?
