Just like a tree ring can tell you his age and give a
clue about life that has been living, as well as long tusk of narwhal. The
latest research led by a professor of bioscience in Denmark's Aarhus University
has shown that this strange Arctic Pope adds a typical tusk layer every year.
And not only these layers offer insight into the age of narwhal (they are
already known to live up to 50 years) but the conditions in which they live -
such as pollution levels, temperature levels, and even their diet consisting
of. You are what you eat!

According to Guinness World Records, the first person
charged with speeding was Walter Arnold from the village of England Paddock
Wood, Kent. On January 28, 1896, Arnold looked four times the speed limit on
the 19th century Benz - but because the speed limit at that time was only two
miles per hour, it meant he wasn't too fast with today's standards. The police
had to drive him on top of his bicycle, issued a ticket for £ 4 7 and produced
Arnold's quick difference.

Some smells the same pleasant with the "new car
smell" - and not only because it's fun in a new car. But while the scent
may be strangely satisfying, the fact is enough just a combination of 50+
chemicals (known as "volatile organic compounds") released into the
car, rot quickly from time to time. Concentration found in a typical new car is
not dangerous, but among the VOC which makes many new smells of cars is
established nail polish, automatic fuel, and petroleum.

Do you get the feeling that there are more twins
around today than before? Not? Well, you must, because according to a new study
in the journal of human reproduction, "twin rate" has increased a
third since the 80s from 9 to 12 twins per 1,000 deliveries. At present, which
adds around 1.6 million twins born every year throughout the world - which
means one of every 42 babies is twins. Helping encourages this is the
increasing use of medically assisted reproduction, and delays in giving birth
to children (twins have been found to increase with mother's age).

It sounds like something from a horror film, but it's
too real: Elysia CF. Marginata, a type of sea slug, has been found not only
survive, but to be able to grow a new body from him. Ecologists at the Nara
Female University in Japan found that, a few hours after their head was cut off
from their bodies, the slug chief had bitten the algae as if nothing had
happened. In about 20 days, one third of the sea slugs studied has completely
grown their bodies.

Those who think everything on this planet has been
found might not look close enough. Small chameleons are found in North
Madagascar and measuring only 28.9 millimeters are believed to be the smallest
reptile on earth. The Itty Bitty Chameleon was recently discovered and reported
in the January 2021 edition of the scientific report. But there is one thing
about this big creature for its size: male genitals measuring almost 20% of
their body length.

Food waste is a big problem. How big? About 931
million metric tons. That's how much food that researchers with the United
Nations estimate was wasted in 2019, according to the 2021 food waste index
report, which surveyed 54 countries, found that the majority of food wasted
(61%) came from homes and other food services. Produce 26% of food wasted.
Foodstore produces only 13% of food waste.

Feet are very complex body parts. Every leg contains
26 bones, and 33 joints and 19 muscles, which work together to allow various
motions and movements. But many of these bones remain vulnerable bones
throughout a childhood, slowly hardened with bones as many years continues.
According to the community of Chiropodist Ontario, all bones on the feet do not
completely harden until a person is around 21 years old!

The surprising side effects of pregnancy are that
nails and hair grow faster than usual. This is due to changes in hormones and
increased blood circulation and metabolism that supply nutrients. According to
Amy O'Connor, writing for what is expected, pregnant people also "may feel
thicker and look more shiny and healthy than usual." Even though she
warned that it could sometimes mean that expecting "maybe suddenly
proutstrand in their [they] did not."

You might think that it's just a fish that has gills, but there are some sea snake species that breathe through their skin too. For example, hydrophist Cyanoccinctus has been found breathe through the top of its own head. It has a small hole and a collection of blood vessels at the top of its head to take oxygen from sea water and send it to the reptile brain while moving under water.
