Living Will
- News: Justice M S Sonak, who serves on the Goa Bench of the Bombay High Court, recently became the first person in Goa to register a “living will”.
- Living Wills:
-
- Definition: Advance directives, also known as living wills, are legal documents that allow individuals to specify their preferences for medical treatment in the event they become incapacitated and are unable to communicate their wishes.
- Purpose: Living wills give individuals control over how they should be treated in case of incapacitation.
- Clarity for Family Members: Advance directives provide clarity to family members who would otherwise have to make difficult decisions on medical care and life support systems.
- Validity of living wills in India:
-
- The Supreme Court, in a landmark judgment in 2018, accepted and recognised the “right to die with dignity” as part of the fundamental ‘Right to Life’ under Article 21 of the constitution.
- The court observed that every adult individual with the mental capacity to make an informed decision has the right to refuse medical treatment, and life support systems, by executing an advance medical directive or a living will.

- The revised guidelines mandate explicit mention of the guardian or close relative authorized to make decisions regarding withdrawal of medical treatment in the event of the maker’s incapacitation.
- Revised Composition and Expertise of Medical Boards:
- Previously, medical boards were required to consist of three doctors with a minimum of 20 years’ experience in various medical fields.

- Timely Review Processes:
- Both the primary and secondary medical boards are now expected to provide their opinions within 48 hours of receiving a case referral, facilitating quicker decision-making processes.
- Recourse in Case of Disagreement:

Greedflation
- News: Rising food prices in the US might be due to misleading narrative of “greedflation”.
- Definition of Greedflation:
-
- Greedflation simply means (corporate) greed is fuelling inflation.
- Unlike typical inflation scenarios where price increases result from higher input costs or increased demand, greedflation occurs when corporations exploit existing inflation by raising prices far beyond their actual input cost increases.
- Profit-Driven Price Increases:
-
- The rising prices under greedflation are driven more by corporate profit-seeking than by traditional economic factors.
- Economic Impact:
-
- This practice maximizes profit margins but also further fuels inflation, creating a cycle that exacerbates economic inequality.

Thismia Malayana
- News: A distinctive plant, Thismia Malayana, which steals nutrients from underground fungi, has been published as a new species in the open-access journal PhytoKeys.
- Definition: Thismia Malayana is a newly discovered species of plant found in the tropical rainforests of Peninsular Malaysia.
- Classification: It belongs to a group of plants known as mycoheterotrophs, which do not perform photosynthesis like most plants.
- Nutrient Acquisition:
-
- Unlike typical plants, mycoheterotrophs such as Thismia malayana act as parasites, stealing carbon resources from fungi on their roots.
- This adaptation exploits the mycorrhizal symbiosis, a mutually beneficial relationship between fungi and a plant’s root system.
- Mycorrhizal Symbiosis:
-
- In mycorrhizal symbiosis, fungi help trees absorb water and nutrients from the soil, while trees provide fungi with sugars produced through photosynthesis.
- This partnership is essential for the health and growth of both organisms.
- Parasitic Behavior:
-
- Thismia malayana deviates from the mutual exchange in mycorrhizal symbiosis by acting as a parasite, siphoning off carbon resources from fungi without offering anything in return.
- Habitat and Adaptation:
-
- Thriving in the low-light conditions of dense forest understories, Thismia malayana’s highly specialized flowers are pollinated by fungus gnats and other small insects.
- Despite its small size, it is typically found hidden in leaf litter and grows near tree roots or old rotten logs.
- Conservation Status: Despite its sensitivity to environmental changes, Thismia malayana has been classified as Vulnerable according to the IUCN Red List.
Musankwa Sanyatiensis
- News: A 210 million-year-old dinosaur fossil, Musankwa Sanyatiensis, uncovered by scientists along the shoreline of Spurwing Island at Lake Kariba has sparked global interest.
- Discovery and Location: Musankwa sanyatiensis is a newly identified dinosaur species discovered from fossils found along the shores of Lake Kariba in Zimbabwe.
- Naming:
-
- The dinosaur’s genus name, “Musankwa,” originates from the name of the houseboat scientists utilized during their expeditions to the research site.
- Its species name, “sanyatiensis,” references the Sanyati River, which flows into Lake Kariba.
- Significance:
-
- It marks the first dinosaur to be named from the Mid-Zambezi Basin of northern Zimbabwe in over 50 years.
- Additionally, it is only the fourth dinosaur to be named from Zimbabwe, following previous descriptions.
- Geological Context:
-
- The rocks containing this new specimen date back to the Late Triassic period, approximately 210 million years ago.
- Fossil Specimen:
-
- Musankwa sanyatiensis is represented by the remains of a single hind leg, including thigh, shin, and ankle bones.
- Evolutionary Analysis:
-
- Evolutionary analysis indicates that it belonged to the Sauropodomorpha group, consisting of bipedal, long-necked dinosaurs prevalent during the Late Triassic.
- Interestingly, it appears to be closely related to contemporaneous species found in South Africa and Argentina.
- Physical Characteristics:
-
- Weighing approximately 390 kg, Musankwa sanyatiensis was one of the larger dinosaurs of its era and primarily inhabited swamp areas.
- Lake Kariba:
-
- Lake Kariba is a lake in central Africa, between Zambia and Zimbabwe.
- Lake Kariba in Zimbabwe is the world’s largest man-made lake and reservoir by volume.
-
-
- Today, the Kariba Dam hydroelectric power station, situated on the lake, serves as a vital source of electricity for both Zimbabwe and Zambia.
