🔆Nipah Monoclonal antibodies trial
India may begin human clinical trials for a novel Nipah monoclonal antibody, MBP1F5, in 2025, following regulatory approval. A similar trial will also be conducted in Bangladesh.
Nipah virus has a high mortality rate of 40% to 75%, with recent outbreaks reported in Kerala, India, and widespread infections in Bangladesh since 2001
The novel monoclonal antibody is in phase-1 trials in the U.S., led by the U.S. Department of Defence. These trials are funded by the Coalition for Epidemic Preparedness Innovations (CEPI).
Preclinical studies have shown the antibody to be highly potent against Nipah virus and safe at all tested doses. It binds to the Nipah virus F protein, preventing the virus from entering a host cell.
This antibody offers protection for at least six months, covering both known strains of Nipah and the Hendra virus, ensuring time for vaccine immunity to develop.

🔆Researchers at IIT Madras have demonstrated a novel method to create mineral nanoparticles using microdroplets of water
The research reveals that microdroplets of water can break down minerals into nanoparticles, a process that is not possible with bulk water.
Due to their small size and closely packed water molecules, microdroplets are more reactive and capable of engaging in chemical reactions at a much faster rate, sometimes up to a million times faster than bulk water.

🔆Dyson sphere
✅A Dyson Sphere is a hypothetical megastructure proposed by physicist Freeman Dyson in 1960.
✅It's essentially a massive, spherical structure constructed around a star to harness its energy output.
✅While often depicted as a solid shell encasing the star completely, various designs and configurations have been theorized over the years.
📍Concept and Purpose:
✅Energy Harvesting:The primary purpose of a Dyson Sphere is to capture and utilize the energy emitted by a star. This energy can be used for various purposes, including powering advanced civilizations, interstellar travel, or even terraforming planets.
✅Sustainability:Dyson Spheres offer the potential for nearly unlimited energy, making them attractive for civilizations seeking long-term sustainability and growth.

🔆Sucralose:
✅Sucralose is a no-calorie sweetener that can be used to lower one’s intake of added sugars while still providing satisfaction from enjoying the taste of something sweet.
✅While some types of sweeteners in this category are considered low-calorie (e.g., aspartame) and others are no-calorie (e.g., sucralose, monk fruit sweeteners, and stevia sweeteners). Collectively, they are often referred to as sugar substitutes, high-intensity sweeteners, nonnutritive sweeteners, or low-calorie sweeteners.
✅Like other no-calorie sweeteners, sucralose is intensely sweet. It is about 600 times sweeter than sugar.
✅It can be used as an ingredient in any type of food or beverage.
✅Sucralose is exceptionally stable, so foods and beverages sweetened with sucralose stay sweet under a wide range of conditions.
✅Sucralose is made from a process that begins with regular table sugar (sucrose); however, sucralose is not sugar.
