BSL-4 Containment Facility in Gandhinagar On 13th January 2026, the Union Home Minister laid the foundation stone of a Bio-Safety Level-4 (BSL-4) Containment Facility and laboratory in Gandhinagar, Gujarat. This is only the second civilian BSL-4 laboratory in India after the National Institute of Virology (NIV), Pune. In late 2024, DRDO established a dedicated defence-sector BSL-4 facility in Gwalior, Madhya Pradesh. What is a BSL-4 Facility? Aspect Details Containment Level BSL-4 is the highest level of biological containment. Pathogen Category Designed for research on extremely dangerous and highly infectious pathogens that often lack effective vaccines or treatments. Major Uses Used…

GlowCas9: A CRISPR Protein that Lights Up Gene Editing In December 2025, scientists at the Bose Institute, Kolkata developed GlowCas9, a novel CRISPR protein capable of emitting light while carrying out gene editing. The innovation introduces a new method to directly visualise genome editing activity in real time. What Makes GlowCas9 Special? Feature Details Real-time Visualisation GlowCas9 allows scientists to visualise genome editing activity while it is occurring inside living cells. Bioluminescent Cas9 It is a bioluminescent version of Cas9 created by fusing Cas9 with a split nano-luciferase enzyme derived from deep-sea shrimp proteins. Light-emitting Mechanism When Cas9 folds correctly…

Brain-Computer Interface to Restore Natural Speech Researchers recently developed a breakthrough Brain-Computer Interface (BCI) capable of restoring naturalistic speech for individuals suffering from severe paralysis. The system converts brain activity directly into audible speech in near real time, marking a major advancement in assistive neurotechnology. Key Features of the BCI System Feature Details AI-driven Translation The BCI uses artificial intelligence to instantly translate brain signals into audible speech with near-synchronous voice streaming. Neural Signal Source The system samples neural activity from the motor cortex, the brain region controlling speech-related movements. AI Speech Processing Functions similarly to voice assistants such as…

“Transneuron” Recently, researchers developed a single artificial neuron called a “transneuron”, capable of replicating activity associated with multiple regions of the human brain. The breakthrough is considered a significant step toward machines with more human-like sensing, adaptability, and computational behaviour. What is a Transneuron? Feature Details Multi-functional Capability The transneuron can switch between motor, pre-motor, and visual functions. Difference from Conventional Artificial Neurons Unlike traditional artificial neurons that perform a single task, transneurons can adapt to multiple neural functions. Information Processing Processes information using electrical pulses in a manner similar to biological neurons. Scientific Importance Brings machines closer to adaptive…

Miniature TnpB-based Genome Editing Tool Recently, Indian researchers created a hypercompact genome-editing system using TnpB proteins, offering a homegrown alternative to proprietary CRISPR-Cas technologies. What is the TnpB-based Genome Editing System? Aspect Details Nature of TnpB TnpB is a tiny, next-generation genome-editing enzyme that works like CRISPR but is far more compact. Working Mechanism It functions as a molecular scissor, cutting plant DNA at a precise target location guided by a matching RNA sequence. Key Features and Advantages Feature Explanation Hypercompact Size TnpB has only 400–500 amino acids, compared with 1,000–1,400 in Cas9 and around 1,300 in Cas12a.…

Antibiotic-Producing Thermophilic Bacteria In a new breakthrough, researchers discovered thermophilic bacteria with strong antibiotic potential in the Rajgir hot spring located in Nalanda, Bihar. What are Thermophiles? Aspect Details Nature Thermophiles are heat-loving bacteria that thrive at temperatures between 45°–70°C. Habitat Commonly found in hot springs, thermal vents, compost piles, and even microwave ovens. Antibiotic Potential Some thermophiles produce powerful antibiotics to survive in low-competition, mineral-rich environments. PT Facts Thermophiles: Extremophiles that grow at high temperatures. Hot Springs: Important sites for discovering heat-stable enzymes and novel microbes. Antimicrobial Resistance: New antibiotic-producing…

Scientists Discover Key to Delaying Female Fertility Decline In a groundbreaking study, scientists from the National Institute of Animal Biotechnology (NIAB) found a promising way to slow down ovarian aging, the natural decline in the number and quality of egg cells, or oocytes, in females. What the NIAB Study Found Finding Details Key Protein The study found that a protein called Cathepsin B (Cat B) plays a key role in speeding up ovarian aging. Function of Cat B Cat B is an enzyme that breaks down other proteins in the body. Main Outcome Reducing Cat B activity helped preserve the…
