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:
India has proposed the “Maratha Military Landscapes of India” for UNESCO World Heritage List recognition in 2024-25. Developed between the 17th and 19th centuries, these military landscapes showcase an exceptional fortification system envisioned by Maratha rulers. The network of forts, spanning the Sahyadri mountain ranges, Konkan Coast, Deccan Plateau, and Eastern Ghats, integrates distinctive landscapes. Notable components include Salher fort, Shivneri fort, Raigad, Vijaydurg, and others. The Maratha Military ideology, dating from the 17th century, continued until Peshwa rule in 1818 CE.

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:
China has imposed a ban on the import of ruminants and related products from Iraq due to a bluetongue disease outbreak. Bluetongue is a non-contagious viral disease affecting domestic and wild ruminants, transmitted by insects’ particularly biting species of Culicoides midges. The virus belongs to the Reoviridae family with 24 identified serotypes. Symptoms vary, but sheep are most severely affected. The disease is globally distributed in regions where the insect vector thrives, posing a threat to various species with transmission facilitated by the infected vector.

Notes:
Recently, Mesolithic rock paintings were unearthed at Sitamma Loddi, Gattusingaram, in Telangana’s Peddapalli district. Discovered on a hillock in a dense forest, the paintings adorned a 1,000-foot-long, 50-foot-high sandstone rock shelter. The Mesolithic, or Middle Stone Age, bridged the gap between the Paleolithic and Neolithic periods, spanning approximately 12,000-10,000 years ago. Notable for the transition from large chipped stone tools to microliths, small tools affixed to bone or wood handles for making implements like saws and sickles, it marked a pivotal era in human cultural development.

Notes:
A recent discussion between the United States and China have focused on joint efforts to combat the influx of fentanyl into the U.S. Fentanyl, a potent synthetic opioid (a type of drug), has wreaked havoc in America and is linked to ingredients produced in China. The drug, 50 times stronger than heroin and 100 times stronger than morphine, is FDA (Food and Drug Administration) -approved for severe pain but is also illegally manufactured and sold recreationally, often mixed with other drugs, posing a high risk of addiction and fatality in large doses or when combined.

Notes:
Researchers recently uncovered a new genus and five novel millipede species in African jungles. Millipedes, not insects but arthropods related to lobsters, crayfish, and shrimp, boast approximately 12,000 global species. These cylindrical or slightly flattened invertebrates, often black or brown, inhabit moist areas with decaying vegetation. Ranging from 2 to 280 mm, they possess multiple segments, each housing two pairs of legs and internal organs. Although not poisonous, some species produce irritating fluids. Nocturnal scavengers, millipedes primarily feed on decaying plants and occasional dead insects.

Notes:
The endangered Forest Owlet, Athene blewitti, was recently sighted three times in the Melghat Tiger Reserve, Maharashtra. Initially described in 1873, it was considered extinct after 1884 but rediscovered in 1997. Endemic to central India, it’s observed in various states. Inhabiting diverse ecosystems, it’s small, stocky, with distinctive features. Diurnal and hunting during the day, it preys on rodents, reptiles, and insects. With an IUCN Red List status of Endangered and CITES Appendix I, conservation efforts are crucial.

Notes:
Namibia’s President, Hage Geingob, has died at 82 following cancer treatment. The first prime minister post-independence, he became Namibia’s third president in 2014, securing re-election in 2019. Geingob, a key figure since independence from South Africa, held the record for Namibia’s longest-serving prime minister before assuming the presidency. His passing marks the end of a significant era in Namibian political history.

Notes:
The government has undertaken crucial measures to safeguard the Black-Necked Crane, as revealed by the Union Minister of State for Environment. This medium-sized crane species, residing in high-altitude wetlands of the Tibetan plateau, faces threats like habitat loss due to climate change, agricultural changes, pollution, and environmental contamination. With a distribution in India, China, and Bhutan, it holds a Near Threatened status on the IUCN list and is listed in Schedule I of the Wild Life (Protection) Act, 1972, and Appendix I of CITES.
