Green promise: Silver cockscomb isn’t a troublesome weed for Karnataka’s Soliga tribe
- For the Soligas, known for their traditional knowledge of ecology, silver cockscomb is a nutritious leafy green vegetable that grows well even on fallow land and in drought-like conditions
- Silver cockscomb is a beautiful but troublesome weed. It can spread quickly and suppress the growth of other crops, affecting their yield. It also attracts insects, caterpillars, worms and moths that can harm crops.
- In Karnataka’s Chamarajanagara district, where silver cockscomb is referred to as anne soppu, farmers of the Soliga tribe say controlling the weed can cost up to Rs 2,000 per acre (0.4 hectare) per year. Yet they do not consider silver cockscomb a weed.
- For the Soligas, known for their traditional knowledge of ecology, silver cockscomb is a nutritious leafy green vegetable that grows well even on fallow land and in drought-like conditions.
- Also known as lagos spinach, the weed belongs to the Amaranthaceae family, which includes economically important plants like spinach (Spinacia oleracea), beetroot and quinoa. The plant is known as Celosia argentea in scientific lexicon, kurdu in Marathi and pannai keerai in Tamil.
Healthy add-on
- Although it is of the same family as spinach, it does not pose the same risk to kidneys. Spinach leaves are high in calcium, oxalates, vitamin K and potassium, which can impair kidney function and lead to formation of kidney stones.
- In comparison, silver cockscomb leaves have lower levels of oxalic acid (0.2 per cent) and phytic acid (0.12 per cent), says the World Vegetable Center.
- Though scientists are discovering the benefits of silver cockscomb now, communities worldwide have long known its usage and benefits. Believed to have originated in tropical Africa, according to the Royal Botanic Gardens, Kew, UK, silver cockscomb grows abundantly in South and Southeast Asia, Latin America and parts of the US and Australia.
Soligas
- Soligas are an indigenous tribe of Karnataka, inhabiting the peripheral forest areas near Biligiri Rangana Hills and Male Mahadeshwara in the Chamarajnagar district of Karnataka.
- The Soligas were dependent on hunting and shifting agriculture traditionally.
- They are the first tribal community living inside the core area of a tiger reserve in India to get their forest rights officially recognised by a court of law.
Integrate mpox with HIV, STI prevention & control programmes: WHO
- New HIV guidelines on viral suppression unveiled at international AIDS conference
- The World Health Organization (WHO) released new scientific and normative guidance for human immunodeficiency virus (HIV)
- The United Nations’ health agency also recommended countries integrate mpox detection, prevention and care with existing and innovative HIV and sexually transmitted infection prevention and control programmes.
- More than 80 per cent of them reported sex as the most probable route of getting infected with mpox.
Monkeypox
- Monkeypox is a viral zoonotic disease with symptoms similar to smallpox, although with less clinical severity.
- The infection was first discovered in 1958 following two outbreaks of a pox-like disease in colonies of monkeys kept for research — which led to the name ‘monkeypox’.
- Symptoms:
- Infected people break out in a rash that looks a lot like chicken pox. But the fever, malaise, and headache from Monkeypox are usually more severe than in chicken pox infection.
- In the early stage of the disease, Monkeypox can be distinguished from smallpox because the lymph gland gets enlarged.
- Transmission:
- Primary infection is through direct contact with the blood, bodily fluids, or cutaneous or mucosal lesions of an infected animal. Eating inadequately cooked meat of infected animals is also a risk factor.
- Human-to-human transmission can result from close contact with infected respiratory tract secretions, skin lesions of an infected person or objects recently contaminated by patient fluids or lesion materials.
- Transmission can also occur by inoculation or via the placenta (congenital monkeypox).
- Vulnerability:
- It spreads rapidly and can cause one out of ten deaths if infected.
- Treatment and Vaccine:
- There is no specific treatment or vaccine available for Monkeypox infection,
- But the European Union has recommended a Small Pox Vaccine, Imvanex to treat monkeypox after the WHO declared monkeypox a global health emergency.
- There is no specific treatment or vaccine available for Monkeypox infection,

More than 87,000 Indians gave up their citizenship till June, says S Jaishankar
Modes of losing Indian Citizenship
- The Citizenship Act 1955 lays down the three modes by which an Indian citizen, whether a citizen at the commencement of the Constitution or subsequent to it, may lose their citizenship. These are,
- By Renunciation:
- An Indian Citizen of full age and capacity can renounce his Indian citizenship by making a declaration to that effect and having it registered.
- But if such a declaration is made during any war in which India is engaged, the registration shall be withheld until the Central Government otherwise directs.
- When a male person renounces his citizenship, every minor child of him ceases to be an Indian citizen.
- Such a child may, however, resume Indian citizenship if he makes a declaration to that effect within a year of his attaining full age, i.e., 18 years.
- By Termination:
- If a citizen of India voluntarily acquires citizenship of another country, then the citizenship of India gets terminated.
- This provision does not apply during times of war.
- If any question arises as to whether, when, or how any person has acquired the citizenship of another country, it is to be determined by such authority and in such manner as may be prescribed by the rules.
- By Deprivation:
- It is a compulsory termination of citizenship of India.
- A citizen of India by naturalization, registration, domicile and residence may be deprived of his citizenship by order of the Central Government if it is satisfied that:
- The citizen has obtained the citizenship by means of fraud, false representation, or concealment of any material fact;
- The citizen has shown disloyalty to the Constitution of India;
- The citizen has unlawfully traded or communicated with the enemy during a war;
- The citizen has, within five years after registration or neutralization, been imprisoned in any country for two years;
- The citizen has been ordinarily resident out of India for seven years;
Scientists unveil method to power devices using air humidity!
Hygroelectricity
- Hygroelectricity is the generation of electricity from the humidity of the air.
- It is a type of renewable energy that has the potential to be a major source of power in the future.
- How it works?
- The key to harvesting electricity from humid air lies in a tiny device comprising two electrodes and a thin layer of material filled with nanopores.
- These nanopores, each less than 100 nanometres in diameter, allow water molecules from the air to pass through the device.
- As these molecules move from an upper chamber to a lower chamber, they interact with the edges of the nanopores, leading to a buildup of electric charge imbalances between the chambers.
- This process effectively transforms the device into a miniature battery, generating continuous electricity.
- Just as clouds create electrical charges and give rise to lightning bolts during storms, this revolutionary device converts air humidity into usable electricity.
- Advantage of Hygroelectricity: Unlike other renewable energy sources such as solar and wind, air humidity is continuously available, making it a sustainable reservoir of energy.
- Challenges:
- Currently, the fingernail-sized device can only produce electricity equivalent to a fraction of a volt.
- Scaling up the technology to meet practical energy demands is a significant hurdle.
Electrode
- An electrode is a solid conductor that conducts electricity to and from an electrolyte, which is an electrically conductive solution or molten salt.
- Electrodes are used in many different applications, including batteries, electrochemical cells, and electroplating.
- There are two main types of electrodes: anode and cathode.
- The anode is the electrode where oxidation occurs, and the cathode is the electrode where reduction occurs. Oxidation is the loss of electrons, and reduction is the gain of electrons.
- In a battery, the anode is the negative terminal, and the cathode is the positive terminal.
- When the battery is connected to a circuit, electrons flow from the anode to the cathode. This flow of electrons creates an electric current.
Nanopores
- Nanopores are tiny holes that are typically on the order of a few nanometres in diameter.
- They can be found in a variety of materials, including biological cells, synthetic membranes, and even graphene.
Hubble Sees Boulders Escaping from Asteroid Dimorphos
DART Mission
- NASA''s DART mission was a spacecraft designed to test a method of deflecting an asteroid for planetary defense, using the "kinetic impactor" technique (in simplest terms means smashing a thing into another thing).
- DART was the first-ever space mission to demonstrate asteroid deflection by kinetic impactor.
- The target of the spacecraft was a 160-meter-wide asteroid known as Dimorphos, which is a moonlet in orbit around the larger asteroid, Didymos.
- It was launched in November 2021.
- DART spacecraft successfully collided with Dimorphos on 26 September 2022, altering the asteroid''s orbit by 33 minutes.
- It is the first-time humanity intentionally changed the motion of a celestial object in space.
Boulders
- It is a geological term for a rock fragment that is larger than 25.6 centimetres (10.1 inches) in diameter.
- Boulders can be made up of various types of rocks, including igneous, sedimentary, and metamorphic rocks.
- The composition of a boulder depends on the geology of the area in which it formed.
