SCIENCE AND TECHNOLOGY

 

1. Indian Scientists Develop AI Sensor to Identify Snake Venom with 95% Accuracy: Indian researchers developed a laboratory sensor that distinguishes cobra venom from viper venom using liquid crystals and artificial intelligence. The study, published in Sensors and Actuators A: Physical, reported 95% identification accuracy and a sensing time of four minutes. The sensor uses a textile grid impregnated with liquid crystals. Contact with venom changes the grid’s optical appearance, creating patterns for analysis. A deep-learning model, MobileNetV3-Large, processes these patterns and classifies the sample as cobra or viper venom. The system detected both venom types at concentrations as low as 45 micrograms per millilitre. The research paper is titled “A deep learning-enhanced liquid crystal sensor for the rapid discrimination of snake venoms: A case study on cobra and viper”. The reported results concern cobra and viper venom; they do not establish identification of all snake species or venom types.

 

2. DCGI Approves Zytorvi for Advanced Esophageal Cancer: On 21 October 2026, the Drugs Controller General of India (DCGI) approved Zytorvi (toripalimab) with cisplatin and paclitaxel as first-line treatment for adults with unresectable advanced, recurrent or metastatic esophageal squamous cell carcinoma (ESCC). The approval is Zytorvi’s second indication in India, after its approval for nasopharyngeal carcinoma. The oesophagus is a muscular tube that carries food from the throat to the stomach. ESCC is a cancer arising from the squamous cells lining the oesophagus; it accounts for about 80% of esophageal cancer cases in India. “Unresectable” describes a tumour that cannot be removed through surgery, while “metastatic” refers to cancer that has spread to distant parts of the body. First-line treatment is the initial treatment used for a disease.

 

3. MoD Signs ₹770-Crore BEL Radar Contract: On 21 October 2026, the Ministry of Defence (MoD) signed a contract worth approximately ₹770 crore with Bharat Electronics Limited (BEL) to procure Improved Low Level Light Weight Radars (LLLR-I). The contract was signed in New Delhi in the presence of Defence Secretary Rajesh Kumar Singh and officials from the MoD and BEL. The Indian Army will use the system for air-defence surveillance against aircraft and unmanned aerial threats. The LLLR-I detects and tracks fighter-sized aircraft, mini drones and micro drones. Its system can automatically prioritise incoming aerial targets, including Unmanned Aerial Systems (UAS). It can provide target indications to weapon systems through wired or wireless communication. Remote control of radar modes and display of the air situation picture are also system functions. The LLLR-I is an upgraded version of the Defence Research and Development Organisation-designed Aslesha radar. It is man-portable and intended for deployment in plains, deserts and high-altitude areas. The system’s fixed antenna panels are mounted on a tripod.
