Current Affairs Quiz - February, 2024

Notes:
Alzheimer’s disease is a prevalent brain condition, responsible for 60-80% of dementia cases, affecting memory, thinking, and daily activities. Recent studies suggest rare medical accidents can transmit the disease between humans. Typically impacting those aged 65 and older, with unknown exact causes, it involves genetic, environmental, and lifestyle factors. Symptoms range from forgetting recent events to serious memory loss, and while there’s no cure, certain medications and therapies can temporarily manage the symptoms.

Notes:
The Ministry of Finance released a report titled The Indian Economy: A Review in January 2024. The report was released a few days before the Union Budget for 2024-25 was presented in Parliament on February 1. The Ministry of Finance is made up of five divisions: Economic Affairs, Revenue, Expenditures, Investment and Public Asset Management, and Financial Services.

Notes:
The National Conference on Promotion of Seaweed Cultivation, chaired by the Union Minister of Fisheries in Koteshwar, Kutch, Gujarat, showcased diverse seaweed cultivation methods (Monoline, tube-net, and rafts). CMFRI, CSMCRI, and NFDB demonstrated these techniques. Seaweeds, macroscopic algae lacking true roots and leaves, thrive in marine and coastal waters. They are classified into four groups based on pigments that absorb specific wavelengths of light. The event aimed at fostering seaweed development and enhancing awareness about its potential in India.

Notes:
The Delhi government has launched the Delhi Solar Policy 2024 to boost solar power adoption. Residents can install rooftop solar panels, leading to zero electricity bills and potential income from excess power sales to the grid. The policy targets 4500 MW of solar power by 2027, up from the previous goal of 1500 MW. Stemming from the 2016 policy, which yielded 1500 MW capacity, the new policy aims to curb air pollution, cut electricity costs, and promote sustainable energy in Delhi.

Notes:
Neuralink is the first company to implant a computer chip in a human brain. Neuralink is a neurotechnology company founded in 2016 by Musk and seven other scientists and engineers. The company’s implant, known as the “Link,” is a small device that’s surgically placed inside the human brain. Neuralink says its device can interpret neural activity so a person can operate a computer or smartphone by simply thinking. The company ultimately hopes to use the brain-machine interface to restore sensory and motor functions in people with disabilities, treat neurological conditions like dementia and depression, and even enable telepathic communication.

Notes:
The US government recently shut down China-backed hacking group “Volt Typhoon,” active since at least 2021. Specializing in espionage and targeting critical infrastructure, Volt Typhoon utilized stealth, living-off-the-land techniques, and preinstalled utilities. The group compromised small office/home office devices, maintaining persistence with stolen credentials. Known for routing traffic through hacked network equipment, such as home routers, Volt Typhoon made detection challenging.

Notes:
Astro Sat, India’s inaugural multi-wavelength astronomy mission, successfully measured the X-ray polarization of the Cygnus X-1 black hole system. Discovered four decades ago, Cygnus X-1 is among the first confirmed black hole systems in our galaxy. The black hole is 20 times the Sun’s mass, with a companion supergiant star (40 times more massive) in a binary system. Located 400 times farther than Earth-Sun distance, the gravitational pull forms an accretion disk, generating soft X-rays.

Notes:
Banaras Hindu University (BHU) inaugurates North India’s first human DNA bank, equipped with an Automated DNA Extractor Machine developed indigenously under the ‘Make in India’ initiative. Installed at the Gnyaneshwar Lab in the Zoology Department on January 30, 2024, the machine minimizes plastic usage, ensuring environmental sustainability. It efficiently extracts DNA from various biological materials, accommodating 32 samples in 30 minutes. The initiative stemmed from a three-day conference on Personalized Medicine held in March 2023, where BHU expressed readiness to establish a genome bank inspired by Estonia.

Notes:
Researchers discovered a new fungus species, Trichoglossum syamviswanathii, in Kerala. Trichoglossum is a genus of fungus known as “hairy earth tongues” due to its filamentous structure. The fungus, with 55 identified genera and 21 recognized species globally, exhibits saprotrophic behavior and can be found in plant roots as endophytes. Predominantly distributed in tropical and temperate forests across five continents, these fungi play a crucial role in decomposing organic matter.

Notes:
The GRAPES-3 experiment, situated in Ooty, India and operated by the Tata Institute of Fundamental Research, made a significant discovery in the cosmic-ray proton spectrum, revealing a new feature at 166 TeV. Equipped with air shower detectors and a large muon detector, GRAPES-3 aims to investigate the origin, acceleration, and propagation of cosmic rays, including the existence of the “Knee” in their energy spectrum. It also explores the production of highest-energy cosmic rays, astronomy of multi-TeV γ-rays, and the impact of the Sun on Earth.
