What are the most fascinating science facts?

 1. A human organ that no-one knew about has been hiding in plain sight all this time. Called mesentery, it connects the intestine to the abdomen and is believed to perform important functions for the body ranging from helping the heart to aiding the immune system.

2. The Earth appears to have a whole new underground continent called Zealandia. The discovery itself isnʼt new – some geologists have been arguing for its existence for many years. However, in 2017 a team of scientists concluded Zealandia fulfils all the requirements to be considered a drowned continent.

3. Pugsʼ cute little flat faces are the result of a genetic mutation. Their features have been strongly linked to a gene variant called SMOC2.

4. For the first time in human history, gene-editing has been performed to fix a mutation for an inherited disease in embryos. Using a powerful tool called Crispr-Cas9, scientists successfully altered the DNA in defective embryos so they were no longer programmed to develop congenital heart failure.

5. Your appendix might not be a useless organ after all. Research suggests it might play a role in the immune system as a secondary defensive organ, acting as a “safe house” for helpful gut bacteria.

6. Giant penguins about the size of a grown man waddled around New Zealand about 59 million years ago.

7. The worldʼs smallest fidget spinner is 100 microns wide. It is smaller than the width of a human hair and is barely visible to the naked eye.

8. Lungs do more than help us breathe – a surprising discovery has found they also make blood. The organ, present in mammals, is believed to produce more than 10 million platelets (tiny blood cells) per hour.

9. A new state of matter exists (alongside solid, liquid and gaseous states) and it is known as time crystals. Created in the lab, the outrageously hard-to- grasp time crystals are structures that repeat periodically in time rather than space, potentially defying the laws of physics.

10. Great apes, including chimpanzees and orangutans, have absolutely no appreciation of music whatsoever. Research has shown they canʼt tell the difference between Beethoven and Bieber, and that music is all just meaningless sound to them.

Water can move against gravity!

Water can easily run against the gravitational pull when moving up narrow pipes. The process is described as ‘Capillary Action’. Water moves up in the narrow spaces without any assistance and against the gravitational force. This ability of the liquid proves that gravitational force can’t control the movement of every matter present on earth. At times, other forces (Surface tension, in this case) can defeat it.

Here are some fascinating science facts that many people don’t know about:


• You know about boiling point of water, and melting point of water, but might not be knowing about triple point of water on which water boils and freezes at the same time. It occurs when the temperature and pressure is just right for the three phases (gas, liquid, and solid) of a substance to coexist in thermodynamic equilibrium. 


• We can prove Pythagoras theorem with the help of liquid containers. Here’s how:


• According to Suvi Gezari of John Hopkins University, "When the star is ripped apart by the gravitational forces of the black hole, some part of the star's remains falls into the black hole, while the rest is ejected at high speeds”. These spurt out plasma jets span hundreds of light-years.

• Rain is a very good source of vitamin B12, as it is the last pert of water cycle. The microorganism present in air, rooftops, and minerals of rivers (which get evaporated) are said to be quite efficient in producing vitamin B12. So next time your mom chides you for dancing in rain, tell her this science fact.

• Sunflowers are famous as hyperaccumulators amongst scientists due to their ability to accumulate and clean the toxic chemicals from the environment.

The majority of Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, Moon and the various stuff in our nearby planetary group, whenever included, comprise about 0.2% of the aggregate mass of our Solar system[1]. The rest 99.8% is the mass of the Sun!

You can fit the various planets in our close planetary system, one alongside one another, between the Earth and the Moon[2].

Photons take around 40,000 years to go from the Sun's center to its surface, however just around 8 minutes to go from the Sun's surface to the Earth[3].

Presentation to radiation can cause malignant growth yet can likewise murder cancer[4].

The twin oddity is a psychological test that exhibits the inquisitive appearance of time ***** in present day material science, as it was presented by Albert Einstein through the hypothesis of relativity.

Think about two twins, named Biff and Cliff. On their twentieth birthday celebration, Biff chooses to get in a spaceship and take off into space, going at about the speed of light. He travels around the universe at this speed for around 5 years, coming back to the Earth when he is 25 years of age.

Precipice, then again, stays on the Earth. At the point when Biff returns, incidentally, Cliff is 95 years of age.

The Eiffel Tower can be 15 cm taller during the summer

When a substance is heated up, its particles move more and it takes up a larger volume – this is known as thermal expansion. Conversely, a drop in temperature causes it to contract again. The mercury level inside a thermometer, for example, rises and falls as the mercury’s volume changes with the ambient temperature. This effect is most dramatic in gases but occurs in liquids and solids such as iron too. For this reason large structures such as bridges are built with expansion joints which allow them some leeway to expand and contract without causing any damage.
