includes six hundred eleven thousand
mushroom mold and other fungi species
289,000 plant species 7.8 million of
animal species you get the idea
oh and researchers didn't even try to
count the number of bacteria on earth
earth is rotating at a breakneck speed
that's why an object will go a teeny

transparent head so you can see what
he's thinking there are more trees on
our planet than stars in the Milky Way
while our home galaxy can boast of from
100 to 400 billion stars the number of
trees on earth exceeds 3 trillion Pluto
was discovered in 1930 and lost its
planetary status in 2006 within this
rather long time it didn't even manage
to make a full orbit around the Sun the
former planet needs 248 earth years to
complete its orbit showers are famous

hashtag symbol has an official name
octothorpe it's a made-up word that was
created in the same place where the
telephone came from Bell Laboratories
some scientists are pretty sure that
dinosaurs once lived on all continents
yep even in Antarctica then when we find
dinosaur bones all over the planet
because in some places soil and weather
conditions help to fossilize the remains
in others they simply decomposed talking
about dinos there could be many more
species than people think their bones
were simply too small to be preserved
for millions of years the Sun weighs
three hundred thirty thousand times as
much as our planet it's so ginormous
that you could fit earth inside the star
1 million three hundred thousand times
and how about this the Sun contains
99.85% of all the mass in our solar
system 10 human parts have only 3
letters and their names rib jaw eye lip

about persistence there was an astronaut
named Don Lynn who waited for 19 years

the culprit is the bacteria on your skin
they break the sweat down which causes
an unpleasant odor
octopus's lay from 20,000 to 100,000
eggs at a time
the mother octopus doesn't eat for half
a year protecting the eggs when baby
octopuses get born they aren't bigger
than rice grains the human skeleton
completely regenerates itself every 10
years it's an ongoing process happening
at the cellular level that's why you
always have a blend of old and new bones
in your body the human body hasn't
stopped evolving yet more and more
people get born with an extra bone in
their needs this tiny bone is called a
favela it's not something that hasn't
existed before in the 19th century 18%
of people had this bone at the beginning
of the 20th century only 11% of humans
were born with favelas but in 2018 about
39% of the world population had a favela
by the way scientists are still unsure
about its purpose I guess it's on a
need-to-know basis the inhabitants of

the alphabet but they do have on average
15 rows of incredibly strong teeth
they're already born with a set of teeth
and can protect themselves from the baby
age if they lose a tooth another one

krill the sun's atmosphere stretches far
beyond its visible surface our planet is
within its reach exactly why solar wind
gusts create such a breathtaking
phenomenon as the northern and southern
lights the fire hydrant was first
invented in the early 1800s
unfortunately its patent was lost in a
fire when the Patent Office burned down
only one hundred years later the fire
hydrant was reinvented a bolt of
lightning can get five times hotter than
the surface of the Sun so their earth

spiders on earth can live without food
for more than two years it's nearly
impossible to distinguish coil of
fingerprints from human ones loopy
whirling ridges on koalas fingers are

clear of powerlines because those give
off flashes of ultraviolet light plus 35
different animal species are also
sensitive to UV radiation among mammals
only apes and humans don't see
ultraviolet rays
streams sound as if they're babbling
because air bubbles they contain get
captured by water and burst if you want

in robots to learn more about these
creatures people can't stand the heat
and acidity of that environment dogs
nose prints can't be used for their
identification like fingerprints are
used for humans each nose print is
absolutely unique people experience
motion sickness because their brain gets
contradictory information from different
body parts let's say you were on a ship
your internal air feels the movement of
the waves but your eyes don't see it the
brain tries to combine these two
separate feelings but gets confused oh
boy time to find the railing and fast if

billion
your eyes cornea is the only body part
that doesn't get any blood supply it
simply doesn't have any blood vessels it
takes oxygen straight from the air and
gets its nutrition from tears and a
special liquid your eyes produce horses
can't breathe through their mouths a
flap of tissue blocks their throat at
all times except when the animals eating
it prevents the horse from inhaling food
but it also means the animal can only
breathe through its nostrils
woodpeckers can pick the wood up to 20
times per second and make 8,000 to
12,000 packs per day the chief coffee
taster who works for a caustic coffee
has his tongue insured for 13 million
dollars his taste buds are as important
for his profession as vocal cords for a

that's the reason your skin feels
discomfort during and after a flight
hippos have pink sweat which isn't

their arms against their bodies like
birds do vantablack is the darkest
material in the world it absorbs more
than 99% of light and makes 3d objects
look like 2d ones the material is made
of tiny hollow carbon tubes on the area
of less than half a square inch there
are 1000 million nanotubes grown in a

your stomach and esophagus are covered
with more than 100 million nerve cells
scientists think that these nerve cells
are your second brain they can determine
your mood and emotions thus the phrase
follow your gut when something extremely
cold touches the roof of your mouth be
it ice cream or icy winter air the nerve
center located there panics it starts a
nerve reaction and it swells blood
vessels in the head trying to heat the
brain but then why don't your eyes get
cold when it's freezing there are no
temperature receptor cells there plus
the biggest part of the eyeball is
inside the skull and gets warm by the
blood flow inside the largest tire

million tiny tires every year Facebook
once created two AI chat box that could
talk to each other but the chat BOTS
started to communicate in a language no
one but them could understand the
experiment had to be shut down after
that the mimic octopus has a perfect
defense system it can not only change
its colour but also take the shapes of
other sea creatures birds fly in V
formations to save their energy those
flying in the front row create air
swirls with their wings and birds flying
in the back catch these swirls and don't
need to spend so much energy this
formation also helps all the birds to
see the leader
the m100 galaxy is 55 million light
years away from Earth this is a
mind-boggling distance if someone from
that galaxy was looking at our planet
right now they would see the extinction
of dinosaurs and finally point Nemo in
the South Pacific Ocean lies so far away
from any land mass that the closest
human beings are often astronauts on
board the International Space Station
and only when it passes overhead no
wonder another name of this point is the
