- Corona: World Health Organisation (WHO) had designated Omicron variant (B.1.1.529) as a “variant of concern (VOC)”. First reported from South Africa. Also found in Israel and Belgium. Botswana and Hong Kong. दक्षिण अफ़्रीका से पाया गया कोरोना वायरस का नया ओमीक्रोंन स्वरूप- जो अन्य स्वरूप से ज़्यादा संक्रामक और ख़तरनाक है।
- Sci-6 Corona: Can an RT-PCR test detect infection with Omicron? Ans. this variant is that it could be detected in some of the RTPCR diagnostic tests (BUT NOT ALL) 2) most RT-PCR tests in India might not be able to distinguish between Omicron and other variants. 3) RT-PCR tests can only confirm whether the person has an infection or not. They are not designed to determine which particular variant has infected the person. 4) GENOME testing of the sample required to find variant but it’s expensive. पारंपरिक RT-PCR test क्या कोरोना वायरस के नए ओमिक्रोन स्वरूप को पकड़ सकता है। थोड़ा मुश्किल है उसके लिए अलग से जीनोम परीक्षण करना होगा, इसमें ख़र्चे लगते है
- Science- Corona: A pulse oximeter is a small clip-like device which, attached to a fingertip, earlobe, or toe, calculates the amount of oxygen in blood. It was used widely during the corona pandemic to check the oxygen level. 😍 oximeter has a small electronic processor and a pair of LEDs, one of which emits red light; the other infra red. The lights pass through the finger, and the device senses what comes through the other side. Oxygenated haemoglobin absorbs more infrared light and allows more red light to pass through than deoxygenated hemoglobin. The amount of light that is transmitted is measured by the processor, 😍 A blood oxygen saturation rate 95 per cent and higher is considered normal. 🤔 critics alleged that pulse oximeter is are not giving proper reading if skin has dark pigmentation. पल्स-ओकसिमीटर नाम का साधन जो खून में ऑक्सीजन की मात्रा को लापता है। हालाँकि अश्वेत चमड़ी वाले व्यक्तियों में यह साधन सही आंकड़े नहीं दिखा था ऐसा आरोप।
- Science-6 Corona: VARIANTS OF CONCERN: The WHO currently lists 5 variants of concern: ■ Omicron (B.1.1.529), identified in southern Africa in November 2021 ■ Delta (B.1.617.2), which emerged in India in late 2020 ■ Gamma (P.1),Brazil in late 2020 ■ Beta (B.1.351), in South Africa in early 2020 ■ Alpha (B.1.1.7), in Britain in late 2020. So, Omicron is having similarities with Delta (both of them have the codename “B.1. ).

- Sci-Heath: UK proposed ’to clear country’s first long-acting injectable treatment for HIV-1 infection in adults using a combination of the injections cabotegravir with rilpivirine. While HIV is still incurable, but the virus can be controlled by modern treatment. However, for some patients daily oral tablets difficult due to side effects, toxicity, and other psychosocial issues such as stigma. But this injection combo need to be taken only once every 2 months.

- Science: 6-Public Health: HELA Cells: they are cervical cancer tutor cells from Henrietta Lacks, a Black tobacco farmer of USA (1950s). These cells are unique because they continue to multiply/double every day even in the laboratory outside human body. HELA cells have been used by 1) Jonas Salk used the cells to develop the polio vaccine, 2) Identify the human immunodeficiency virus (HIV), 3) develop the cervical cancer vaccine. 4) SARS-CoV-2 corona vaccine etc. 2020 marked her birth centenary so WHO installed her statue in Bristol (UK). 😥 ethical concerns: HELA tumour cells were given away for research without patient’s consent and pharma companies have made millions of dollars, but family got nothing. अमेरिकी अश्वेत महिला हेनरिएटा लेक्स के शरीर से निकाले गए कैंसर कोष, प्रयोगशाला में रोज़ दुगनी होते हैं। इन “हेला-सेल/कोष” की मदद से ढेर सारे चिकित्सा/वैज्ञानिक आविष्कार हो पाए हैं- जैसे की पोलियो टीकाकरण, कोरोना टीकाकरण। हालाँकि फार्मास्युटिकल कंपनियों ने बिलियन डॉलर बना लिए लेकिन परिवार को कुछ पैसा नहीं दिया।

It is the fastest spinning confirmed white dwarf, using magnetic propeller system (सफ़ेद बौना सितारा जो की अपना पूरा ईंधन समाप्त कर चुका है और सिकुड़कर ठंडा हो रहा है)
History Culture from November week4
- Culture: Vajrayana or Tantric Buddhism -based on the concept of “mindfulness” or Dhyana -founded in India around the 6th or 7th centuries. This became the foundation for Chan (Chinese), Zen (Japanese) and Tibetan Buddhism. Tibetan Buddhism – significant presence in Mongolia and Russia Kalmykia region. The spread of Buddhism, whether through conquest or trade, also coincided with the transmission of secular knowledge from the Indian subcontinent – like traditional Indian medicine (Aayush), manufacturing (sugar) and the astro-sciences into these regions. China uses Buddhism for soft Diplomacy over neighbouring countries. India too should develop Buddhist tourist circuit for more people to people connect with ASEAN and Shanghai Cooperation Organisation (SCO) nations. बौद्ध धर्म के साथ जुड़े हुए स्थानों पर पर्यटन को विकसित कर भारत आसियान समूह और शंघाई समूह के देशों के लोगों के साथ रिश्ते बेहतर कर सकता है
