Multiple Sclerosis: It is a long-lasting (chronic) disease of the central nervous system. In people with MS, the immune system attacks cells in the myelin, the protective sheath that surrounds nerves in the brain and spinal cord. Damage to the myelin sheath interrupts nerve signals from your brain to other parts of your body. The damage can lead to symptoms affecting your brain, spinal cord, and eyes. Eventually, the disease can cause permanent damage or deterioration of the nerve fibres. MS affects women more than men. The disorder is most commonly diagnosed between ages 20 to 40, but it can be seen at any age. There are many possible causes of MS, including: Autoimmune disorders; Infectious agents, such as viruses; Environmental factors; Genetic factors.It varies widely between patients and depends on the location and severity of nerve fibre damage in the central nervous system. In severe cases, a person may experience paralysis, vision loss, and mobility problems. There’s no cure for multiple sclerosis. However, there are treatments to help speed the recovery from attacks, modify the course of the disease, and manage symptoms.
Solar Orbiter: It is a Sun-observing satellite with 10 science instruments, all designed to provide unprecedented insight into how the sun works. It is conceived to perform a close-up study of our Sun and inner heliosphere-the uncharted innermost regions of our Solar System. It is a joint mission of the European Space Agency (ESA) and NASA. It is the most complex scientific laboratory ever to have been sent to the Sun. It will take images of the Sun from closer than any spacecraft before and, for the first time, look at its uncharted polar regions. The mission, launched on February 10, 2020, released its first images in June of that year. After multiple gravitational assist manoeuvres at Earth and Venus, it started its full science operations in December 2021. It follows an elliptical orbit around the sun, with the closest point, the perihelion, at about 25 million miles (40 million kilometres) from the sun, which is closer than the orbit of Mercury. Instruments: It carries six remote-sensing instruments to observe the Sun and the solar corona and four in-situ instruments to measure the solar wind, energetic particles, and electromagnetic fields. The mission is scheduled to last until at least 2027.
Garba Dance: It is a ritualistic and devotional dance performed throughout the State of Gujarat. It is celebrated for nine days during the festival of Navratri. The festival is dedicated to the worship of the feminine energy or Shakti. The cultural, performative, and visual expressions of this feminine energy are expressed through the Garba dance. The performative and visual celebration of Garba takes place within homes and temple courtyards, public spaces in villages, urban squares, streets, and large open grounds. Garba thus becomes an all-encompassing participatory community event. In addition to being a religious ritual, Garba fosters social equality by diluting socio-economic, gender, and rigid sect structures. It continues to be inclusive and participative by diverse and marginalised communities, strengthening community bonds. This dance form is the 15th cultural item from India to make it to the UNESCO list
