2. ACE2 enzyme

Recently, a team of researchers at Johns Hopkins University in the US created a nasal spray that could block the coronavirus from entering the lungs and causing infection.

Why in News?

Researchers have created thin, thread-like strands of molecules called supramolecular filaments capable of blocking the virus in its tracks.
The key to this approach is the way that the filaments carry a receptor called angiotensin converting enzyme-2, or ACE2.
ACE2 provides the entry point for the coronavirus to hook into and infect a wide range of human cells.
The team's newly developed filament, called fACE2, serves as a decoy binding site for the virus, with each filament offering several receptors for the COVID-19 spike protein to attach to, and silences ACE2's biological functions to avoid potential side effects

What is ACE2:

It is a protein on the surface of many cell types and tissues including the lungs, heart, blood vessels, kidneys, liver and gastrointestinal tract.
It is an enzyme that generates small proteins – by cutting up the larger protein angiotensinogen – that then go on to regulate functions in the cell.
ACE2 is present in all people but the quantity can vary among individuals and in different tissues and cells.
It is present in epithelial cells, which line certain tissues and create protective barriers.
ACE2 is a vital element in a biochemical pathway that is critical to regulating processes such as blood pressure, wound healing and inflammation, called the renin-angiotensin-aldosterone system (RAAS) pathway.
ACE2 helps modulate the many activities of a protein called angiotensin II (ANG II) that increases blood pressure and inflammation, increasing damage to blood vessel linings and various types of tissue injury.

3. Gangasagar Mela

West Bengal ministers have demanded National Mela status for Gangasagar mela as record pilgrims have come to the mela this year claiming that the annual pilgrimage was turning out to be the biggest religious gathering in the country.

About Gangasagar Mela:

It is known as the world’s second largest human congregation after Kumbh.
It happens every year during Makar Sankranti.
The mela is held at Sagar Island.
It has been mentioned in Indian epics such as the Ramayana and Mahabharata, putting its existence as early as 400 BCE.
The pilgrims after taking a dip in Ganga also visit the temple of Kapil Muni.

Who is Kapil Muni:

Kapila or Maharishi Kapila is a Vedic sage (rishi) traditionally considered to be the original proponent of the Samkhya system of Indian philosophy.
He is said to have lived in the Indian subcontinent, around the sixth or seventh century C.E.
Kapila is described within the Puranas as an incarnation of Vishnu.
He is known for teaching a process of liberation known as bhakti yoga.
Buddhist sources present Kapila as a well-known philosopher whose students built the city of Kapilavastu
He is not only renowned in Hinduism, but also in Buddhism.
Kapila shared many similarities with Buddha, including an emphasis on meditation as a technique for removing suffering, belief that the Vedic gods were subject to limitations and conditions, and dislike for ritual and Brahmanic doctrines.

Where is Sagar Island Located?

Sagar Island, westernmost island of the Ganges-Brahmaputra delta lies in West Bengal
It lies at the mouth of the Hugli (Hooghly) River, an arm of which separates it from the mainland to the east.

5. Galactic halo

Astronomers have recently detected in the stellar halo that represents the Milky Way's outer limits a group of stars more distant from Earth than any known within our own galaxy - almost halfway to a neighboring galaxy.

What is a Galactic halo?

Galactic halo is a nearly spherical volume of thinly scattered stars, globular clusters of stars, and tenuous gas observed surrounding spiral galaxies, including the Milky Way.
Galactic halo is dominated by invisible dark matter, whose presence is only measurable through the gravity that it exerts.
Only about 1% of a galaxy’s stellar mass resides in its halo, and due to this low luminosity, the observation of halos in other galaxies is extremely difficult.

What is Stellar halo?

It is the visible portion of a galactic halo.
It is composed of globular clusters and field stars which have high space velocities that can take them far out of the galactic disk.
Stellar halos may hold some of the best preserved fossils of the formation history of galaxies.

What are Globular clusters?

They are stable, tightly bound clusters of tens of thousands to millions of stars.
They are associated with all types of galaxies.
They are more densely populated, with populations ranging from tens of thousands to millions of stars.
The intense gravitational attraction between the closely packed stars gives globular clusters their regular, spherical shape.

What is meant by a field star?

Stars that are not connected with an astronomical object being studied but which happen to appear in the same field of view when the object is observed through a telescope. Typical examples of field stars are those that appear in the foreground of a telescopic image of a distant galaxy.
A field star is not part of any stellar cluster such as a globular cluster or open cluster.

6. Nicobar long-tailed Macaque

Recent research in Great Nicobar Island (GNI) shows that habitat alterations can increase human-wildlife conflict, adversely affecting the populations and health of the animals and leaving them vulnerable.

About Nicobar long-tailed macaque:

It is a subspecies of the larger family of long-tailed macaques found across South-East Asia.
This particular subspecies is distinct from its cousins in appearance, behaviour and geographical location.
The macaque is found in only three of the Nicobar islands—Katchal, Little Nicobar, and Great Nicobar—with GNI being home to the largest population.
Protection status
- IUCN: Vulnerable

Key facts about Great Nicobar Island(GNI)

GNI lies between the Bay of Bengal and the Andaman Sea in a tectonically sensitive zone. The largest of the Nicobar group of islands at 910 square kilometres.
Great Nicobar is home to two national parks; Campbell Bay and Galathea National Parks.
Tribal groups: The Shompen and Nicobarese tribal peoples reside on this Island.

7. Intelligent knife (iKnife)

New research led by the Imperial College of London has recently found an intelligent knife (iKnife), which can be used to diagnose womb cancer within minutes.

Why in news?

According to the World Cancer Research Fund International, womb or endometrial cancer is the 6th most commonly occurring cancer among people with uteruses.

How it works:

The knife uses electric currents on biopsy tissue and then analyses the vapourised aerosols from the tissue in a mass spectrometer to give real-time information about activity in the tissue.
The study noted that the knife reliably diagnosed endometrial cancer in tissue within seconds with an accuracy of 89%. This would greatly minimise the delays faced by patients who wait for a normal histopathological diagnosis.

9. Neelakurinji

Recently, The Ministry of Environment, Forest and Climate Change (MoEF) has listed Neelakurinji under Schedule III of the Wildlife (Protection) Act, 1972, including it on the list of protected plants.

Why in news?

According to the recent orders, those who uproot or destroy the plant will invite a fine of ₹25,000 and three years imprisonment. The cultivation of this and its possession is not allowed,
Neelakurinji has been included on the list when the Centre expanded the earlier protected list of six plant species to 19.

About Neelakurunji

Neelakuruj is scientifically known as Strobilanthus Kunsthaus,
It is a shrub that grows in the shola forests of the Western Ghats in South India.
The plant is named after the famous Kunthi River which flows through Kerala’s Silent Valley National Park, where the plant occurs abundantly.
It is found at an altitude of 1,300-2,400 metres.
This flower blooms once in 12 yearsas the pollination of flowers needs a longer period.
It is mainly found in the states of Kerala, Tamil Nadu, and Karnataka.

The Wildlife (Protection) Act, 1972

This act was enacted for the protection of plants and animal species.
Also, this act established schedules of protected plant and animal species; hunting or harvesting of these species was largely outlawed.

10. Lymphatic Filariasis

Union Minister for Health & Family Welfare recently said that India is committed to eliminating Lymphatic Filariasis by 2027 in the National Symposium on India’s Roadmap to Eliminate Lymphatic Filariasis (LF) held at Vigyan Bhawan, New Delhi.

What is Lymphatic Filariasis?

The Lymphatic filariasis disease commonly known as elephantiasis is a neglected tropical disease. Infection occurs when filarial parasites are transmitted to humans through mosquitoes.
This impairs the lymphatic system and can lead to the abnormal enlargement of body parts, causing pain, severe disability and social stigma.
It is caused by infection with parasites classified as nematodes (roundworms) of the family Filariodidea. There are 3 types of these thread-like filarial worms:
- Wuchereria bancrofti, which is responsible for 90% of the cases
- Brugia malayi, which causes most of the remainder of the cases
- Brugia timori, which also causes the disease.

Global Initiatives to eradicate Lymphatic Filariasis

WHO’s road map 2021−2030: sets global targets and milestones to prevent, control, eliminate or eradicate 20 diseases
Global Programme to Eliminate Lymphatic Filariasis (GPELF): WHO established this to stop the transmission of infection by mass drug administration (MDA) of anthelmintics and to alleviate the suffering of people affected by the disease through morbidity management and disability prevention (MMDP).
