(a) Brain-Eating Amoeba
Naegleria fowleri is an ameba (single-celled living organism) that lives in soil and warm fresh water, such as lakes, rivers, and hot springs. It is commonly called the “brain-eating ameba” because it can cause a brain infection when water containing the ameba goes up the nose. It is a microscopic organism that can only be seen with a microscope. The amoeba enters the body through the nose and can cause a severe brain infection known as primary amebic meningoencephalitis (PAM).
Signs and Symptoms:
They may initially resemble the meningitis-related symptoms of headache, nausea, and fever.
In the later stages, one may experience seizures, hallucinations, a stiff neck, and possibly a coma.
The infection spreads quickly and usually results in death after five days. According to the CDC (Centers for disease control and prevention), PAM’s initial symptoms appear one to 12 days after infection.
Treatment:
Because these infections are uncommon and spread swiftly, researchers haven’t yet found any cures that work. Amphotericin B, azithromycin, fluconazole, rifampin, miltefosine, and dexamethasone are being used by doctors to treat it.
Impact of Climate Change:
The CDC predicts that as temperatures rise around the world, more people will become infected with Naegleria fowleri since the amoeba primarily lives in warm freshwater bodies. The organism may sometimes survive at even greater temperatures and thrives best in high temperatures up to 46°C.
Recent research has revealed that too much atmospheric carbon dioxide has caused lakes and rivers to warm up. “These circumstances offer the amoeba a more hospitable habitat in which to flourish.
The CDC website notes that during heat waves, when air and water temperatures may be higher than usual, the amoeba may also flourish.

(a) Liquid Sodium is employed as a coolant in nuclear reactors
Liquid sodium is used as a coolant in nuclear reactors. It absorbs energy from the reaction and transfers it to water in steam generators. The steam is then used to turn turbines to generate electricity.

In 1025, Rajendra Chola, the Chola king from Tamil Nadu in South India, launched naval raids on ports of Srivijaya in maritime Southeast Asia, and conquered Kadaram (modern Kedah) from Srivijaya and occupied it for some time. Rajendra overseas expedition against Srivijaya was a unique event in India’s history and its otherwise peaceful relations with the states of Southeast Asia.
The Chola dynasty was at the peak of its influence and power during the medieval period. Through their leadership and vision, Chola kings expanded their territory and influence.
