Science & Technology Current Affairs MCQs

Notes:
A 29-year-old man in Karnataka died after contracting Kyasanur Forest Disease (KFD), also called monkey fever. Kyasanur Forest Disease (KFD) is a tick-borne viral haemorrhagic disease mostly found in southern India, first reported in 1957 from Kyasanur Forest, Karnataka. The virus belongs to the family Flaviviridae, genus Flavivirus, part of the tick-borne encephalitis complex. It is called monkey fever due to its association with monkey deaths.

Notes:
Researchers discovered a new marine worm species named Paraleocrates indica in the muddy banks of the Champa Estuary in the Bay of Bengal. It is the first record of this rare genus from Indian waters and only the third species worldwide in this genus. The worm belongs to the Hesionidae family, known for colourful bristle worms that often live symbiotically with other marine organisms like starfish. It appears reddish, measures 14–35 millimetres, and has a unique eye structure with front eyes five times larger than the back ones.

Notes:
Ministry of Science and Technology announced the establishment of Bio-AI Mulankur hubs to strengthen integration of biotechnology and Artificial Intelligence. Aim is to create integrated closed-loop research platforms where Artificial Intelligence based predictions are tested and validated in laboratories within the same system. This will reduce gap between computational research and experimental results. Initiative is aligned with BioE3 Policy, which stands for Biotechnology for Environment, Economy and Employment. It aims to promote sustainable development, economic growth and job creation through biotechnology. Implementing agencies are Department of Biotechnology and Biotechnology Industry Research Assistance Council.

Notes:
On the 40th Foundation Day of the Department of Biotechnology (DBT), Union Minister Jitendra Singh launched “SUJVIKA”, an AI-driven Biotech Product Data Portal. It has been developed by Department of Biotechnology (DBT) in collaboration with Association of Biotechnology Led Enterprises (ABLE). SUJVIKA is a Trade Statistics Digital Intelligence Platform that provides authenticated and structured data on biotechnology product imports, offering sector-wise insights into biochemical products, industrial enzymes and other biotech imports.

Notes:
Recently, the Meghalaya government issued an advisory after a meningococcal infection scare, urging people to avoid crowded places and follow health protocols. Meningococcal infection is a severe and rapidly progressing disease caused by the bacterium Neisseria meningitidis. It can lead to meningitis, which is inflammation of the meninges covering the brain and spinal cord, or meningococcemia, which is blood poisoning. It spreads through respiratory and throat secretions like saliva during close or prolonged contact. It is less contagious than common cold or flu infections.

Notes:
A recent study has warned that more than one-third of Africa is at risk of the spread of Cassava Brown Streak Disease (CBSD), which is a highly destructive disease affecting cassava crops. CBSD is considered one of the most devastating diseases of cassava, as it severely reduces both the production and quality of cassava tubers (roots), which are an important staple food in many African countries. The disease was first identified in the mid-20th century in the coastal regions of East Africa, and since then it has spread significantly across the African continent.

Notes:
Japan has become the first country to approve stem-cell treatments for Parkinson’s disease and severe heart failure. Sumitomo Pharma received approval for Amchepry, a treatment that transplants induced pluripotent stem (iPS) cells into the brain of Parkinson’s patients. Cuorips, a medical startup, got approval for ReHeart, heart muscle sheets that help form new blood vessels and restore heart function. Both treatments could reach patients as early as summer 2026 under a conditional, time-limited approval system for faster patient access. iPS cells, discovered by Nobel laureate Shinya Yamanaka, can transform into any cell type without using embryos. The approval marks a global first for commercial medical products using iPS cell technology.

Notes:
United States-based Sentynl Therapeutics, part of Zydus Lifesciences, has partnered with South Korea’s PRG S&T to develop Progerinin, a drug for Hutchinson-Gilford Progeria Syndrome (HGPS). Hutchinson-Gilford Progeria Syndrome (HGPS) is an extremely rare genetic disorder that causes rapid aging in children. The disease is caused by a mutation in the LMNA (Lamin A) gene, which normally produces lamin A protein for maintaining cell structure. This mutation leads to the formation of an abnormal protein called progerin, which damages the cell nucleus. The damaged cells die early, resulting in premature aging of the body.

Notes:
Newcastle Disease is a highly contagious viral disease affecting poultry and wild birds, recently reported spreading across Europe and the United Kingdom (UK). It is caused by Avian Paramyxovirus Serotype 1 (APMV-1) and has global distribution. It occurs in three forms: lentogenic (mild), mesogenic (moderate), and velogenic (highly virulent). Transmission occurs via respiratory droplets, exhaled air, and feces of infected birds. Symptoms include respiratory distress (gasping, coughing), nervous signs (paralysis, twisted neck), and diarrhoea.

Notes:
Scientists at the Bose Institute discovered a new gene regulation mechanism in Tuberculosis bacterium (Mycobacterium tuberculosis). Transcription is the process where DNA is copied into RNA by RNA Polymerase (RNAP) for protein synthesis. Earlier, bacteria were believed to follow the Sigma Cycle, where sigma factor binds RNAP to initiate transcription and then detaches. The study found that in TB bacteria, the sigma factor (σF) remains continuously attached to RNAP throughout transcription. This continuous binding helps activate survival genes, enabling bacteria to persist in hostile conditions inside the human body.
