BEES

ABOUT BEES:

Bees are small and wonderful insects. Bees are flying insects closely related to wasps and ants. They collect honey from flowers and store it in their hive. Bees have four wings. Its body has three parts head, abdomen, and abdomen. The color of its body is yellow and black. They are one of the hardworking insects. Bees live in a hive in a swarm. It lives in its community. Bees are very useful to human beings. They give honey and beeswax. One healthy Honey Bee would approximately lay 2,000 eggs in one day. Bees are mainly found in habitats such as tropical rain forests and woodlands, grasslands, and Gardens where there are more flowers and green matters available. Honey bees are small flying insects whose lifespan varies between 170 to 180 days. Honey bees usually live in groups and their queen has a lifespan of more than two years. One bee may fly up to more than 90 thousand miles to collect one pound of honey. In a colony there are three types of bees namely worker bees, drone bees, and queen bees. . Worker bees are the most familiar-looking member of the honeybee hive. Worker bees are all female, and they do almost everything for the hive. The worker bee is given different tasks to do during different stages of her life. Worker bees are responsible for everything from feeding the larvae (the baby bees), to tending to the queen, to cleaning the hive, to collecting food, to guarding the colony, to building honeycomb. Drones are male bees and their sole purpose is to mate with the queen. Unlike the female worker bee, drones do not have stingers and gather neither nectar nor pollen. You can identify drones in the hive by their big round bodies and large eyes. There is one queen bee per hive – she is the mom of all the other bees. She is the only fertile member of the colony and lays about 1,500 eggs a day during spring and summer. The queen will not leave the hive again unless the colony swarms (looking for a new home). Queen bees are distinguished from the other members of the hive by their long abdomens and small wings.

IMPORTANCE OF BEES:

Bees are important to humanity and the world we live in because they provide the most efficient way to pollinate plants. They are especially important because they pollinate our agriculture for free. It’s their work as crop pollinators. This agricultural benefit of honey bees is estimated to be between 10 and 20 times the total value of honey and beeswax.

INTERESTING FACTS ABOUT BEES:

  • A bee produces a teaspoon of honey (about 5 grams) in her lifetime.
  • There are over 20,000 different species of bees. To produce a kilogram of honey, bees fly the equivalent of three times around the world in air miles.
  • Each bee has 170 odorant receptors, which means they have one serious sense of smell. They use this to communicate within the hive and to recognize different types of flowers when looking for food.
  • If the queen bee dies in a honeybee hive the workers can create a new queen bee. They do this by selecting a young larva and by feeding it special food called ‘royal jelly’ the larva develops into a fertile queen.
  • The Honey Bee is the only insect that makes food which human can eat.

NATURAL DISASTERS


ABOUT DISASTERS:

A natural disaster is a major adverse event resulting from natural processes of the Earth. Some of the natural disasters are floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, storms, and other geologic processes. A natural disaster is a major adverse event resulting from natural processes of the Earth. Many Natural disasters damage the environment and the people living in it. Natural disasters are caused due to different reasons like soil erosion, seismic activity, tectonic movements, air pressure, and ocean currents, etc.

TYPES OF NATURAL DISASTERS ARE:

Some of the different kinds of natural disasters are,

  • Earthquake:

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. When the rocks break, the earthquake occurs.

  • Floods:

The major cause of the flood is heavy rainfall. It can be also caused by the melting of snow and ice. It is also caused by Broken Dams.

  • Tsunami:

Tsunami is waves caused by a sudden movement of the ocean surface due to earthquakes, landslides on the seafloor, land slumping into the ocean, large volcanic eruptions, or meteorite impact in the ocean. When tsunami waves become extremely large in height, they savagely attack coastlines, causing devastating property damage and loss of life.

  • Tornadoes:

Tornadoes are caused by the thunderstorms being extremely large, unstable, and with wind shear in the lower region of the atmosphere. Tornadoes often damage power lines, gas lines, or electrical systems, there is a risk of fire, electrocution, or an explosion. Tornadoes can last from several seconds to more than an hour.

  • Volcanic eruption:

Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth’s mantle melts. Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. Health concerns after a volcanic eruption include infectious disease, respiratory illness, burns, injuries from falls, and vehicle accidents related to the slippery, hazy conditions caused by ash. When warnings are been pay attention to, the chances of adverse health effects from a volcanic eruption are very low.

  • Landslide:

Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors. Slides can cause disastrous flooding, particularly when landslide dams across streams are breached, and flooding may trigger slides. A landslide can also block rivers and increase the risk of floods.

  • Hurricanes:

Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. This cycle causes huge storm clouds to form. The major effects of hurricanes are tornadoes, heavy rainfall, high winds, riptide, and death.

  • Thunderstorms:

Thunderstorms arise when layers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere. Thunderstorms can bring heavy rains, strong winds, hail, lightning, and tornadoes. Severe thunderstorms can cause extensive damage to homes and property. Lightning is a major threat during a thunderstorm.

Glowing images of fluorescent reptiles recently discovered by scientists in Africa

Astonishing glow-in-the-dark discoveries were recently made in Africa, after scientists recently discovered reptiles that glow in the dark… literally! Namibia’s geckos shine bright under black lights, as stated in a study recently published in Scientific Reports.

According to the report, the stripes and blots on the reptile prevent it from being identified by predators, and keep them singled out from other geckos. A lot of such discoveries have been made recently across the world. In Australia, platypuses with fluorescent markings were discovered. 

Astonishing glow-in-the-dark discoveries were recently made in Africa, after scientists recently discovered reptiles that glow in the dark… literally! Namibia’s geckos shine bright under black lights, as stated in a study recently published in Scientific Reports.

According to the report, the stripes and blots on the reptile prevent it from being identified by predators, and keep them singled out from other geckos. A lot of such discoveries have been made recently across the world. In Australia, platypuses with fluorescent markings were discovered.

The particular species in question have translucent skin, with even their bones glowing under ultraviolet light.

Dr Mark Scherz from Germany’s University Potsdam, part of the Adaptive Genomics Group recently spoke to Live Science about the astonishing discovery, claiming that the colour was shocking to the researchers.

“Actually it turns out quite a few other species, including geckos, have sufficiently transparent skin that their bones’ fluorescence can be seen through it under a sufficiently strong UV light,” Scherz said.

“We have observed in captivity that, although these animals are largely solitary, they do run up to one another to greet each other after a short period of separation,” Scherz added.

 “They also lick condensation from each other’s bodies. So there are lots of reasons that being able to see each other over long distances would be useful for these geckos,” he further said.

Indian Army Day

When people think about heroes of India, they only and only remember the Indian Army. Let us celebrate Indian Army Day by saluting all the army men and women for their bravery, dedication and patriotism.

Army Day is celebrated on 15 January every year in India, in recognition of Field Marshal Kodandera M. Cariappa taking over as the first Commander-in-Chief of the Indian Army from General Sir Francis Butcher, the last British Commander-in-Chief of India, on 15 January 1949. Today, India will celebrate its 73rd Indian Army Day. The day is celebrated in the form of parades and other military shows in the national capital New Delhi as well as in all headquarters. Army Day marks a day to salute the valiant soldiers who sacrificed their lives to protect the country and its citizens. Army Day strives to motivate people to build a great Nation by knowing about how an Army officer provides his/her full life for the betterment and safety of the people. While celebrations take place across the country, the main Army Day parade is conducted in Cariappa Parade ground in Delhi cantonment. Gallantry awards and Sena medals are also awarded on this day.

K. M. Cariappa

Kodandera Madappa Cariappa was the first Indian Commander-in-Chief of the Indian Army. He led Indian forces on the Western Front during the Indo-Pakistani War of 1947. He was appointed Commander-in-Chief of the Indian Army in 1949. He is one of only two Indian Army officers to hold the Five-star rank of Field Marshal; the other being Field Marshal Sam Manekshaw.

His distinguished military career spanned almost three decades. Born on 28 January 1898, in Madikeri, Kodagu, Cariappa joined the British Indian Army shortly after the end of World War I. He was transferred between multiple regiments early in his career before settling on 1/7 Rajputs, which became his permanent regiment. He was the first Indian military officer to attend the Staff College, Quetta, the first Indian to command a battalion. Several measures taken by Cariappa, such as his refusal to induct former Indian National Army personnel into the Army, kept the organisation out of political affairs and maintained its autonomy.  He died in his sleep on 15 May 1993. India remembers him as a true patriot and a son of the country. 

The primary mission of the Indian Army is to ensure national security and national unity, to defend the nation from external aggression and internal threats, and to maintain peace and security within its borders. It conducts humanitarian rescue operations during natural calamities and other disturbances. The army comprises more than 80% of the country’s active defence personnel. It is the largest standing army in the world, with 12,37,117 active troops and 9,60,000 reserve troops. In 1992, the Indian Army began inducting women officers in non-medical roles. In 2014, India’s army had 3 per cent women and in 2015, India opened new combat air force roles for women as fighter pilots, adding to their role as helicopter pilots in the Indian Air Force. We all have love, respect and admiration for our soldiers and the Indian army as a whole.

Happy Indian Army Day!
