About Kawasaki Disease:

• Kawasaki Disease, also known as Kawasaki syndrome or mucocutaneous lymph node syndrome, is a rare disease that causes fever and inflammation of the blood vessels.
• It occurs mostly in children younger than 5 years old and affects boys more often than girls.
• The disease was first described in Japan by Tomisaku Kawasaki in 1967, and the first cases outside of Japan were reported in Hawaii in 1976.
• The cause of Kawasaki disease is unknown, although more cases happen in late winter and early spring.
• It is the most common form of acquired (not present at birth) heart disease in children in developed countries.
• The condition causes the immune system to attack blood vessels, which become inflamed and swollen.
• It tends to affect the coronary arteries, which carry blood to the heart muscle.
• It can also cause problems with lymph nodes, skin, and the lining of a child’s mouth, nose, and throat.
• It is not contagious, so it cannot spread from person to person.
• Symptoms: Symptoms of Kawasaki disease can appear in two phases and may last several week Common symptoms include:
  • A high fever lasting more than five days.
  • A rash on the main part of the body or in the genital area.
  • An enlarged lymph node in the neck.
  • Very red eyes without a thick discharge.
  • Red, dry, cracked lips and a red, swollen tongue.
  • Swollen, red skin on the palms of the hands and the soles of the feet. Later the skin on fingers and toes peels.
• Treatment:
  • It is often treatable. With early treatment, most children get better and have no long-lasting problems.
  • It is usually treated in the hospital with an intravenous (IV) dose of immunoglobulin (IVIG) antibodies.

About Leaf Spot Diseases:

• Leaf spot is the name given to a group of plant diseases caused by fungi, bacteria, or other microorganisms.
• These pathogens exploit the leaf’s surface and, once established, can quickly proliferate, producing visible spots or lesions.
• The spots on the leaves can be small or large. Leaf spot also interferes with the plant's photosynthesis.
• If left untreated, leaf spot can eventually severely damage the plant’s foliage.
• Heavily infected leaves turn yellow and brown, shrivel, and drop prematurely.
• Almost every region around the world is susceptible to some form of leaf spot disease.
• The prevalence and severity depend on local climate conditions, with humid and wet environments particularly conducive to the spread and growth of these pathogens.
• They are common on vegetables, bedding plants, fruit trees, ornamental trees and shrubs.
• The two main types of leaf spot are either fungal or bacterial, with 85% of plant diseases caused by fungi.
• While not caused by a pathogen, certain environmental conditions can cause symptoms that resemble leaf spots.
  • Factors such as water stress, sun scald, chemical burn from pesticides or herbicides, or nutrient imbalances can lead to spot-like lesions on leaves.
• Leaf spot diseases present a serious threat to global agriculture, impacting food production, economic stability, and environmental health.
• Controlling and preventing leaf spot diseases require a combination of cultural, biological, and chemical methods.

About Pushkarmema curajae:

• It is a new species of cyanobacteria.

Key Facts about Cyanobacteria:

• They are photosynthetic microscopic organisms found naturally in all types of water.
• They were originally called blue-green algae (though they are not true algae) because dense growths often turn the water green, blue-green, or brownish-green.
• They are usually unicellular, though they often grow in colonies large enough to see.
• They are prokaryotic organisms (lack a true nucleus and membrane-bound organelles).
• While often a green or blue-green colour, they can also be white, brown, blue, yellow-brown, or red.
• They live in fresh, brackish (combined salt and fresh water), and marine water.
• They photosynthesise like plants and have similar requirements for sunlight, nutrients, and carbon dioxide to grow and produce oxygen.
• In addition to being photosynthetic, many species of cyanobacteria can also “fix” atmospheric nitrogen—that is, they can transform the gaseous nitrogen of the air into compounds that can be used by living cells.
• They have the distinction of being the oldest known fossils, more than 3.5 billion years old.
• The cyanobacteria have also been tremendously important in shaping the course of evolution and ecological change throughout earth's history.
• The oxygen atmosphere that we depend on was generated by numerous cyanobacteria during the Archaean and Proterozoic Eras.
• High nutrient concentrations can promote a population explosion of these organisms and result in algal blooms, especially during warm weather.
  • Cyanobacterial blooms lead to deterioration of water quality and production of toxins by some species.
  • Exposure to algal toxins has been linked to fatalities of livestock, wildlife, and pets.

About Doppler Weather Radar:

• It is specialized radar that uses the Doppler Effect to produce velocity data about objects at a distance.
• These radar systems can provide information regarding the movement of targets as well as their position.
• Working of Doppler weather Radars:
  • In radars, a beam of energy, called radio waves, is emitted from an antenna.
  • When this beam strikes an object in the atmosphere, the energy scatters in all directions, with some reflecting directly back to the radar.
  • The larger the object deflecting the beam, the greater is the amount of energy that the radar receives in return.
  • Observing the time required for the beam to be transmitted and returned to the radar allows weather forecasting departments to “see” raindrops in the atmosphere, and measure their distance from the radar.
  • Types of weather Radar Bands: Varying frequencies like S-band, C-band and X-band — are commonly used by the IMD in India.
• Applications of Doppler weather Radars:
  • Weather System: It is used to track the movement of weather systems and cloud bands, and gauge rainfall over its coverage area of about 500 km.
  • X-band radar is used to detect thunderstorms and lightning, whereas a C-band radar helps in cyclone tracking.
