Snow is now safe to eat

http://www.abhirajgupta.in/snow-is-now-safe-to-eat.html

Many of you must have seen snow and I am sure you must have played with it enjoying chilly weather.

Snow which was considered earlier unfit to eat is now safe if it is half day old as per Romanian university which published results of 2017 experiments done so far.

Moreover the snow is safer to eat in winter months.

One thing to note is snow is unfit to eat if it two days old as per Istvan Mathe, a professor at one of the Hungarian University.

Few chunks of snow was taken during winter season in central Romania and placed in sterilized containers. Bacteria were grown in this container in temperature ranging from -1 degree Celsius to -17.4 degrees Celsius. Fresh snow had few bacteria but 2 days old snow had many bacteria as microorganisms increase due to impurities in the air.

So what are you waiting for? Enjoy with snow and play and eat it at the same time.

Asteroid coming close to Earth at 42 lakhs km

http://www.abhirajgupta.in/asteroid-coming-close-to-earth-at-42-lakhs-km.html

You must have heard about asteroids coming close to Earth and about to collide. Looks like a fairy tale.

But this is true.

February 4, 2018 which is less than a week from now will witness this when asteroid called “2002 AJ129” will zip past Earth at a speed of 1 lakh kmph and is designated potentially hazardous by NASA scientists.

This is potentially hazardous because the asteroid which is 1.1 Km wide will fly about 42 lakhs Km away from Earth which is considered very close in space terms.

To give an idea on this distance Moon is 3.84 lakhs km away from Earth.

In the early years of its formation asteroids had collided with Earth about 4 billion years ago that resulted in extinction of about 75% species of plants and animals including dinosaurs. This also resulted in climate change.

The proof of such a disaster is The Chicxulub crater located in Mexico’s Chicxulub town.

There are about 190 craters on Earth because of such disasters happened earlier.  Out of this 190 following countries have the maximum craters:

  • Canada-32
  • USA-28
  • Australia-27
  • Russia-19
  • Finland-11
  • Sweden-8
  • Brazil-7
  • Ukraine-7
  • Algeria-4
  • Estonia-4
  • Kazakhstan-4
  • South Africa- 4
  • Others-35

India has 2 craters one in The Lonar Lake in Buldhana district of Maharashtra and another one in Shivpuri district of Madhya Pradesh. These craters are believed to be 52,000 to 5, 70,000 years old and have a diameter of 11 kms.

Water Alligator

Have you ever seen aquatic plants that are sprawling grounds for Alligators?

These were spotted at the side of Salado river, a tributary of Paraguay River and is an off the beaten place that provides a hiding place for small Alligators.

These are giant round water lilies spanning over 1.5 meters (approx 5 feet) that was believed to be extinct about 12 years ago and have given a boost to tourism.

These wonderful plants which are a queen of water lilies are native to Paraguay which and appear every third or fourth southern hemisphere summer.

The scientific name of this plant is Victoria Cruziana. These are also called Alligator Lilies because they are large enough to hide small Alligator.

These lilies are very good in tea making as these fight asthma and bronchial issues and hence authorities have issued warnings to fine anyone who tries to harvest this plant.

OMG!Chilly weather dropping Iguanas from trees

http://www.abhirajgupta.in/omgchilly-weather-dropping-iguanas-from-trees.html

Have you ever heard anyone falling from the tree because of chilly weather?

Iguanas are falling from the trees in USA due to chilled weather.

Iguana is a large arboreal tropical American lizard with a spiny crest along the back and greenish coloration which are found in Mexico, Central America, South America and the Caribbean. These can even be found in Southern belt of USA.

Florida, a south eastern state of USA has become so chilled that Iguana is falling from the tree like overripe mangoes once it climbs it due to bad weather. Iguana is a cold blooded lizard but chill factor has forced Iguana to loosen its grip and fall on the surface.

These herbivorous creatures fall once the temperature nose dives to 10 degrees Celsius. Fellow reptiles-sea turtles also stiffen when the temperature drops.

Residents are advised not to come near Iguanas as they may feel threatened and may bite once they warm up.

Duck like Dinosaurs Species found

http://www.abhirajgupta.in

Dinosaurs have always been a mystery for human being and have always been a subject of experiment and finding something new about them.

Recently a new species of Dinosaurs has been found and is named Halszkaraptor esuilliei after Polish palaeontologist Halszka Osmolska.

This species has a bill like a duck, teeth like a croc’s, a swanlike neck and killer claws, flippers like a penguin but walked like an ostrich. This meat eating Dino can also swim making it the first of its kind having swimming ability. Though the creature could run and swim but it was not able to fly.

This tiny creature only about 45 centimeters tall roamed about 75 million years ago in area which is now Mangolia.

Scientists believe that this creature would likely have been comfortable both on the water surface and on the land, making it a particularly versatile carnivore.

The full research paper was published in the magazine Nature.

How can you tell age of a tree

Do you know age of a tree planted around you?

As a tree grows, its trunk thickens as new wood is added in the middle of the trunk.

The age of a tree can be judged not only  by the thickness and height of a tree but also by the number of circles on the trunk. Each circle indicates roughly a year.

In fact if find any severed tree you will see number of concentric circles in a cross section of trunk growing from the middle outwards. The space between two concentric circles represent annual layer of wood and by counting number of circles themselves the age of a tree can be known.

If you count number of circles in some giant fir trees, it will be many hundreds of years old.

These circles are also known as tree’s rings.

 

Amazon rainforest-more than 350 species found

Amazon rainforest is one of the most famous and dense rainforest in the world. It is also dangerous if anyone goes deep into it.

This world’s largest tropical rainforest lies in much of north western Brazil and extending into Colombia, Peru and other South American countries. It measures about 5.5 Million sq km.

Discoveries by scientists have been mostly in endangered areas threatened by human activities as confirmed by World Wildlife fund (WWF). It took nearly 2 years for scientists to do this task.

Nearly 381 species were found including 216 plants, 93 fish, 32 amphibians, 19 reptiles, 1 bird and 20 mammals.

Some of the interesting new finds include fire-tailed titi monkey, or Milton’s titi, a white ball acari, a nocturnal river fish, and a ‘honeycomb’ stingray, a freshwater ray.

A Brazilian judge has held an order on proposed mining in the area nearly size of Switzerland which is really applaudable otherwise these discoveries will cease in future and we will lose all natural resources.

Why diseases should be named carefully

Disease names can have consequences. Yes this is true.

Government agencies generally do not pay attention whenever disease is named. This is not only in India but is prevalent in other countries also.

Swine flu has nothing to do with pigs but pigs were slaughtered in some countries at the time of spread of Swine Flu. In 2009 Egypt ordered killing of 300,000 pigs to stop its spread.

Spanish flu did not originate from Spain. Many organizations working on Spanish flu brought Spain to limelight claiming it to be the source of this disease and hence Spain could not censor reports and figures on this disease though some of the countries censored this.

HIV was first called “gay related immune deficiency” or GRID leading heterosexuals to underestimate the risk of unprotected sex.

Sudden change in colour of Bosphorus strait connnecting Europe & Asia

Have you heard of Bosphorus Strait?

This strait connects continents of Asia and Europe in Istanbul, capital of Turkey.

People noticed this change as the colour of strait was bluish earlier and changed to milky turquoise this week.

This sudden change has been attributed by scientists to increasing level of pollution in the sea and surge in a species of plankton across the Black Sea.

Other reasons cited are earthquake in the region on 12th Jun 2017 afternoon and surge in micro organism Emiliania huxleyi popularly known as Ehux.

If this continues, it may endanger species of fish and other animals living in the sea in this area and may result in decline in tourism and protests by environmentalists.
