- Key Features:
- Provides sub-nanosecond timing accuracy with deterministic synchronization.
- Simultaneously transmits real-time data and precise time/frequency signals over the same optical fibre.
- Supports thousands of network nodes across long distances with high scalability.
- Is open-source, standards-based, and fault-tolerant, enabling redundant network configurations and high reliability.
- Applications:
- Financial markets: High-frequency trading and accurate transaction timestamping.
- Telecommunications: Secure clock distribution and resilient backup to GNSS/GPS timing.
- Smart power grids: Synchronization of distributed electrical networks.
- Scientific research: Particle accelerators, radio telescopes, and large research facilities.

About Jagannath Temple, Puri
- The Jagannath Temple, located in Puri, Odisha, is one of the Char Dham pilgrimage sites. Built in the 12th century CE by King Anantavarman Chodaganga Deva of the Eastern Ganga dynasty, it was completed under Anangabhima Deva III.
- Temple Style: The temple is a classic example of the Kalinga School of Architecture, a regional variation of the Nagara style, featuring a towering curvilinear Deul (Shikhara).
- Key Features:
-
- Temple Structure: The complex comprises the Deul (sanctum tower), Garbhagriha, Jagamohana (assembly hall), and Bhoga Mandapa (offering hall), crowned by the sacred Nilachakra, an eight-spoked wheel of Lord Vishnu.
- Four Sacred Gateways: The temple has four cardinal entrances—Singha Dwara (East), Hasti Dwara (North), Vyaghra Dwara (West), and Aswa Dwara (South).
- Construction: Built using Khondalite stone without mortar, the stone blocks are held together by iron dowels.

Testosterone Test
Context: The U.S. Department of Defense has mandated annual testosterone screening for active-duty military personnel aged 30 years and above.
Rationale Behind Testosterone Screening by the U.S. Military
- Enhancing Military Readiness: Annual screening aims to identify age-related testosterone deficiency that may impair physical strength, endurance, cognitive performance, and psychological resilience required for modern combat operations.
- Improving Health Outcomes: Early detection enables eligible personnel to voluntarily opt for Testosterone Replacement Therapy (TRT), helping maintain operational fitness, reduce hormone-related health issues, and support long-term force effectiveness.
About Testosterone Test
- A testosterone test is a blood test that measures the level of testosterone, the primary male sex hormone, in the body.
- It is used to diagnose hormonal imbalances, evaluate fertility and sexual development, and monitor hormone-related medical conditions in both men and women.
- Key Information:
- Types of Tests: Includes Total Testosterone (bound + free hormone), Free Testosterone (biologically active hormone), and Bioavailable Testosterone (free and weakly bound hormone).
- Normal Levels: Adult men generally have 280–1,100 ng/dL, while adult women typically have 15–70 ng/dL, though reference values vary among laboratories.
- Applications:
- Diagnosis of Male Hypogonadism and Infertility: The test helps diagnose low testosterone (hypogonadism) in men presenting with reduced libido, erectile dysfunction, infertility, fatigue, or loss of muscle mass.
- Detection of Hormonal Disorders in Women: It aids in diagnosing Polycystic Ovary Syndrome (PCOS), infertility, irregular menstrual cycles, and androgen excess causing excessive facial hair or voice deepening.
- Monitoring Hormone Replacement Therapy (HRT): The test establishes baseline hormone levels before Testosterone Replacement Therapy (TRT) and monitors treatment to maintain safe therapeutic levels while minimizing adverse effects.
- Evaluation of Pubertal Disorders: When combined with Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) tests, it helps determine the causes of precocious (early) or delayed puberty in children and adolescents.

Cyclosporiasis
Context: The U.S. CDC is investigating a sharp rise in cyclosporiasis cases across multiple states, with over 1,600 confirmed infections reported.
About Cyclosporiasis
- Cyclosporiasis is a food- and water-borne intestinal disease caused by the protozoan parasite Cyclospora cayetanensis.
- It primarily affects the gastrointestinal tract, causing prolonged diarrhoeal illness.
- Caused by: The disease is caused by ingestion of Cyclospora cayetanensis, a microscopic parasite. Symptoms usually appear 2 days to over 2 weeks after infection and commonly include watery diarrhoea, nausea, fatigue, abdominal cramps, loss of appetite, and weight loss.
- Spread: Infection occurs through the consumption of food or water contaminated with infective Cyclospora oocysts, especially fresh produce such as leafy vegetables and herbs.
- Person-to-person transmission does not occur because freshly excreted parasites are not immediately infectious.
- Prevention:
- Wash fresh fruits and vegetables thoroughly under running water before consumption.
- Cook food adequately, as heating to about 70°C (158°F) destroys the parasite.
- Maintain proper hand hygiene and follow safe food-handling practices.
- Consume safe drinking water and avoid food from contaminated sources.
- Treatment: The standard treatment is the antibiotic Trimethoprim–Sulfamethoxazole (TMP-SMX), usually administered for 7–10 days.
