Q2     Whichfruits should not be eaten together?

A2     Teamedical, Experienced Medical Team Nov 19

When it comes toeating fruits, it is the best way to enjoy the healthiest and 
most naturalsources of vitamins and minerals. However, not all fruits are 
created equal,and certain combinationsdon’t necessarily pair well together. 
Combining certain fruits cancreate an imbalance of vitamins and minerals, as 
well as produce unpleasantfeelings in the body, such as headaches, stomach 
aches and other digestiveissues. So, what are thefruits you should avoid eating 
together?

First and foremost, you should never mix citrus fruits andbananas. Citrus 
fruits are acidic and tend to be too harshon the stomach when eaten in large 
doses. Meanwhile, bananas are rich inmagnesium and can create an overload of 
minerals in the body when paired withacidic fruits. Also, it’s bestto avoid 
combining watermelon with other fruits, as it contains a lot ofwater and can 
create a very watery texture that doesn’t pair well with otherfruits.

Another pair of fruits you should stay away from is datesand avocados. Dates 
are high in sugar and can overwhelm the bodywhen combined with avocados, which 
are heavy in monounsaturated fats. You should also avoid eatingapples and pears 
together, as apples are acidic and pears can be tooheavy on the stomach.

Finally, mixing melons and grapes is not recommended either. Melons are 
extremely high in sugar and can cause asugar rush if mixed with grapes. 
Additionally, the combination can be hard for the body to digestproperly, 
leading to uncomfortable digestive issues.

It’s best to keepthese combinations in mind when eating fruits. Although some 
of thesecombinations might still be enjoyable, you should be aware of the 
potentialside effects that could be experienced. Eating the right combinations 
of fruitscan help ensure you get the most out of the nutrition that fruits 
provide.

Q3     Howcan the universe be so orderly among infinite possibilities?

A3     Steve Baker, Senior Software Engineer(2013–present)4h

If you dissolve as much salt as you can in a shallow panof hot water - then 
allow it to cool - and then evaporate - you’ll find thatmost of the 
sodium-chloride molecules that had been bouncing around at randomin the liquid 
have spontaneously formed perfect cubes - big enough to seeeasily with the 
naked eye.

This is “order from chaos”.

In the case of the universe, the organizing force is“gravity” pulling things 
together - opposed by the electromagneticforces between atoms keeping 
everything from collapsing into a black hole.

This is why we have planets, stars and galaxies….that’sall just gravity.

Stars form from lighter elements - hydrogen and helium -and gravity pulls those 
elements together with enough force to cause a fusionreaction that results in 
sunlight.

Planets form from the heavier elements - iron, carbon andso forth.

Q4     Whatare some historical records of the reversal of the Earth's magnetic 
field?

A4     Sangram Sagar,Blogger, Content Writer1y

In Ngawha, on theNorth Island of New Zealand, an ancient tree has been 
discovered that containsa record of a reversal of the Earth's magnetic field. 
The tree - an Agathis australis, also known as the Maori name kauri -was found 
during excavation work for the expansion of a geothermal power plant.

The tree was buried 9 meters deep and measures 2.4m indiameter and 30m in 
length. Carbon dating indicated that she lived for 1,500years, between 41,000 
and 42,500 years ago.

 “There is none of this anywhere in the world.This Ngāwhā kauri is unique.”

The lifespan of thekauri tree covers a point in Earth's history when the 
magnetic field nearlyreversed. Magnetic north and south have shiftedpositions, 
but a complete reversal has not taken place. It was almost areversal.

The Earth's magnetic field is believed to be generated bythe iron in the 
planet's core. It produces electricalcurrents that extend into space as they 
move. The magnetic field is really like a barrier that protectsthe planet from 
the solar wind, which is a stream of particles from theSun that could remove 
the Earth's atmosphere, as happened on Mars. With the magnetic field, theyare 
attracted to the poles.

When the magneticfield reverses, it weakens and the planet suffers more from 
the effect of theSun's radiation. Scientists have already linkedextinction 
events to reversals of magnetic fields.

The rings of this kauri tree have a complete record ofthis near reversal, and 
this is the first time a treethat lived through the entire event has been found.

Scientists are nowanalyzing samples from the tree and are led by Chris Turney 
of the Universityof New South Wales, an expert in paleoclimatology and climate 
change for thepast 40,000 years. Theresearch is being funded by the Research 
Council of Australia.

Turney explained:

 “The precious thing is that this huge lonetree grew for about 1700 years in a 
remarkable period in our planet's history,when Earth's magnetic field reversed 
42,000 years ago, a periodknown as the Laschamp Excursion. We're doing a 
detailed analysis ofcarbon-14 in the various rings of this tree.

In the last 83million years, there have been 183 magnetic pole reversals.

This process takes about 7,000 years to complete. Monika Korte, scientific 
director of the Niemegk GeomagneticObservatory at GFZ Potsdam, Germany, says:

 “It is not a sudden movement, but a slow process, during whichthe strength of 
the field becomes weak, most likely the field becomes morecomplex and may show 
morethan two poles for a while, and then it strengthens and aligns itself in 
thesame direction. opposite direction."

According to NASA, magnetic field reversals occur atrandom intervals, although 
over the last 20 millionyears it appears to have settled into a pattern, 
occurring once every 200,000to 300,000 years.

The last total reversal took place about 780,000 yearsago.

Recently, scientists announced that the magnetic northpole had moved 
unexpectedly.

Instead ofconstantly tracking from the Canadian Arctic towards Siberia, it sped 
up somuch that researchers had to update the World Magnetic Model (WMM), which 
is arepresentation of Earth's magnetic field. It is used extensively in 
navigationby the US Department of Defense, the UK Ministry of Defense, and many 
civiliansystems - so knowingexactly where the north and south magnetic poles 
are is of utmost importance.

Q5     Howdoes gingerol help in boosting metabolism?

A5     Shnayas,BCA from Indira Gandhi NationalOpen University (IGNOU) 
(Graduated 2022)1h

Gingerol, found in ginger, is believed to boost metabolismthrough its 
thermogenic effect, which increases the body's production of heat. This 
canpotentially lead to an increase in calorie burning and fat loss. 

Gingerol may help improve insulin sensitivity and reduceinflammation, 
contributing to overall metabolic health. 

However, ginger can be a beneficial addition to a healthydiet, it's important 
to note that its impact on metabolism is just one factor, and lifestyle choices 
play a significant role in overall metabolicfunction.

Q6     Whatare some mind-blowing facts that sound unreal but are actually true?

Ryder Lee,Lives inNew Hampshire Updated 5y

Here are some:

There are no bridges over the Amazon River.

Surprisingly, it took the person who invented the Rubik’sCube an entire month 
to solve it after they created it, and yet thecurrent record in the world is 
less than five seconds.

Sunsets are blue on the redplanet, Mars. Sunsets are red on the blue planet, 
Earth.

Technically, whenyou’re looking up at the sky, you’re actually looking “back in 
time”. Forexample, the bright star Vega is relatively close to us at 25 
light-years away,so the light we see left the star 25 years ago.

The tallest and largest volcano in the solar system islocated on the deserted 
planet of Mars, a neighboringplanet to Earth. The shield volcano is named 
“Olympus Mons”, and is 16 miles(24 kilometers) tall. This means that this 
volcano is approximately three timestaller than Mount Everest.

There could actually be around 500 million planets thatcould support life like 
Earth can in our galaxy.

Q7     Whydid Chandragupta Maurya marry Helina? Is Helina responsible for 
ending the Mauryandynasty?

A7     Rachel Gellar,Student 11h

ChandraguptaMaurya married Helena in a peace treaty in 305 BCE. She was 
surrendered to him by her father Seleucus. It's not known who put this 
condition first. Intermarriage for making peace was common back then soit's not 
someone unusual. Helena was half persian. She was favourite daughter of 
herfather and therefore surrendering her was a huge deal.

As a young girlshe was married to Chandragupta who was in his 30s then. His son 
Bindusara wasalready 15 or 16.

He brought his new wife to Sindh at spent some time withher there. He gave her 
gifts which included moon shapedearrings. Later he alsobrought her to 
Patliputra where she gave birth to his children.

 Their marriage established Epigamiaand provided legitimisation to marriages 
between Yavanas and Indians in boththe Empires.

No, she was not responsible for any decline of Mauryans.
