6/Meghalaya's Living Root Bridges on Tentative List Of UNESCO World Heritage Site 

Meghalaya's famous living root bridge (Jingkieng Jri) has been included in the tentative list of World Heritage Sites of the United Nations Educational, Scientific, and Cultural Organisation (UNESCO). Presently, there are 100 known living root bridges spread across 72 villages in the state. 

These bridges highlight the socio-cultural, social, and botanical links between humans and nature. Villagers, especially Khasi and Jaintia communities, are building and maintaining these bridges for over 600 years. These bridges highlight the socio-cultural, social, and botanical links between humans and nature. It takes almost 15-20 years to build one bridge, but it has a lifespan of several centuries.

5/Three-Headed Sculpture of Lord Vishnu Recovered in Kashmir

 A three-headed sculpture of Lord Vishnu was found in Kashmir. The sculpture was recovered from river Jhelum by some laborers when they were extracting sand at Kakapura area of Pulwama district. Later, it was handed over to the police station, Kakapura.


It's made from greenstone which is very rare and is highly decorated. Although, some parts of the sculpture are missing. The frontal human face is that of ‘Vasudeva’, the right face is of a lion and is called ‘Samkarsana’, the left one boar is north facing and of ‘Aniruddha’. 

4/GSI identified Two New Geological Heritage Sites

Recently, Geological Survey of India (GSI) has identified two geological heritage sites in the Indian Himalayan Region of India. The sites identified are Siwalik Fossil Park, Himachal Pradesh and Stromatolite bearing Dolomite / Limestone of  Buxa Formation, Sikkim.With inclusion of these two sites, there are 34 Geological Heritage Sites in India.


Siwalik Fossil Park


Buxa Formation, Sikkim

The Siwalik Fossil park displays a rich collection of vertebrate fossils recovered from the Siwalik rocks of the area of Plio-Pleistocene age (2.6 million to 11,700 years ago). Site at Mamley exposes litho units of Buxa Formation, Daling Group of Proterozoic age (2.5 billion years to 541 million years ago).

3/UP tops in vegetable and Andhra Pradesh in fruit production.

Uttar pardesh has again become the top vegetable producer, getting back it's position from west bengal after 2 years with a production diffenrce of a million tonnes in 2021-22 Crop year(July- June) . Other top producers are Madhya Pradesh at 20.59 mt, Bihar at 17.77 mt and Maharashtra at 16.78 mt.

Andhra Pradesh continues to hold his position as the top producer of fruits. India’s horticulture output is expected to drop slightly by 0.4% to 333.25 mt in 2021–22 from the previous year (2020–21) as production of vegetables, spices, and plantation crops will decline.

2/6 Scientists finally decoded the first complete Gap free Human Genome.

Around 20 years prior, researchers finished a draft of the human genome and sequence of approximately three billion letters. Yet, the blueprint was just not complete. Eight percent of the genes were missing. Finally, researchers have at long last completed their pursuit. 

When the human genome was first drafted in the early  2000s, genetic sequencing technology was undeniably more restricted. DNA sequencing technology could deliver short bits of genetic code, around 500 letters at a time. The Telomere-to-Telomere (T2T) Consortium has now introduced 3.055 billion base pair sequences.

The finding provided new insights into the workings of the DNA, how it influences the risks of disease and how cells keep it neatly organized.

1/India's First 'STEEL SLAG' road in Surat

Surat is now the first city of India to have a steel slag road made out entirely out of industrial waste. This road is result of joint-venture project by of ArcelorMittal Nippon Steel India, Council of Scientific and Industrial Research (CSIR) India, the Central Road Research Institute (CRRI), and the Niti Aayog at Hazira.

 This six-lane road is 1.2km long and around 1 lakh tonnes of processed steel slag have been used in its construction. Steel slag is a significant issue of worry for the steel industry as the environmental effect of metal waste on landfills is high. There is a ton of potential in steel slag as a road construction material substitute.

This initiative will not only utilise the million of tonnes steel waste produced every year, but it's will also result in more durable roadways.The construction cost of processed steel slag road is 30% less expensive than roads built from natural . "The thickness of the road is additionally 30% lesser than typical ones, while the  durability is significantly longer because of the usage of steel slag.
