Cotton and its uses

Cotton :- Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated from 5000 BC have been excavated in Mexico and between 6000 BC and 5000 BC in the Indus Valley Civilization.

Fatehpur Sikri, India

Fatehpur Sikri is a town in the Agra District of Uttar Pradesh, India. The city was founded in 1569 by the Mughal Emperor Akbar, and served as the capital of the Mughal Empire from 1571 to 1585, when it was abandoned. After his military victories over Chittor and Ranthambore, Akbar decided to shift his capital from Agra to a new location 23 miles (37 km) west south-west, to honour the Sufi saint Salim Chishti. Here, he commenced the construction of a planned walled city, which took the next fifteen years in planning and construction, with a series of royal palaces, harem, courts, a mosque, private quarters and other utility buildings. He named the city Fatehabad, with Fateh, a word of Arabic origin in Persian, meaning "victorious." It was later called Fatehpur Sikri. It is at Fatehpur Sikri that the legends of Akbar and his famed courtiers, the nine jewels or Navaratnas, were born. Fatehpur Sikri is one of the best preserved examples of Mughal architecture in India. Ac...

Nature's Architects

From intricate woven nests to towering termite cities, nature is full of astonishing architects. These creatures don’t need blueprints or tools—just instinct, skill, and a little creativity. Here are five of the most impressive animal builders: 1. The Baya Weaver: The Bird That Weaves Hanging Nests Found across India and Southeast Asia, the  baya weaver  is famous for its  pendant-shaped nests , intricately woven from grass and leaves. These nests hang from thorny trees or palm fronds, often near water to deter predators. Colonies of these nests create a stunning sight, swaying in the breeze like nature’s own hanging gardens. 2. The Harvest Mouse: The Tiny Rodent That Builds on Stilts Weighing just  8 grams , the  harvest mouse  is a master of miniature construction. It weaves  spherical nests  from grass blades, perched high on corn stalks or reeds—sometimes a meter above the ground! These elevated homes keep the mice safe from predators whi...

LEDs from food waste

In an exciting leap toward  greener electronics , researchers at the  University of Utah  have found a way to turn  food waste  into  quantum dots —the tiny crystals that power energy-efficient LED lights in TVs, bulbs, and screens. This breakthrough could pave the way for  non-toxic, eco-friendly LEDs , replacing traditional materials like  cadmium selenide , which can be harmful to the environment. What Are Quantum Dots? Quantum dots are  nanoscale semiconductor particles  that emit vibrant, precise colors when exposed to light or electricity. They’re used in: LED TVs & displays  (for richer colors and better efficiency) Energy-saving light bulbs Medical imaging & solar cells Traditionally, these dots are made from  toxic metals like cadmium , which pose environmental risks when disposed of. But now, scientists are turning to an unlikely alternative:  food waste . From Bread Crusts to High-Tech Lights The Utah...
