Most methods that farmers follow today to control pests and save their crop are mostly reactive, which is done ‘after’ the damage has started. In addition, these methods either destroy other crops, or cause harm to animals that feed on them, or pollute the soil or air. Researchers have now found a ‘green’ and ‘clean’ way to detect crop pests before they start the damage. They have built a highly sensitive sensor that detects pheromones or chemicals released by insects for mating, which signal the presence of pests and thus prompt the farmers to take remedial measures.

Small Intestinal Bacterial Overgrowth (SIBO) is a condition that affects the small intestine and found in those that suffer from Irritable Bowel Syndrome with diarrhea. Today, absence of an accurate diagnostic method prevents early detection and treatment of this condition. Scientists at the SN Bose National Centre for Basic Sciences and Dr. Sujit Chaudhuri from AMRI Hospital, Kolkata, have now developed an improvised accurate diagnostic method that proposes to measure the amount of hydrogen sulphide gas in a patient’s breath. Due to increased bacterial activity in the small intestine, hydrogen sulphide is produced in larger quantities in patients suffering from SIBO. This research hopes to help in early detection and treatment of SIBO, thus guaranteeing a better quality of life for those with IBS and diarrhea.

Detecting leakage of hydrgoen gas has been a major challenge in using hydrogen as fuel for many applications. This is now made easier by a new study by researchers at the Indian Institute of Technology, Roorkee. They have used  nanotechnology based silicon carbide ‘cauliflowers’ to develop a simple, robust, and cost-effective sensor that can detect hydrogen gas at high temperatures and small quantities. This research is a small step that can make using clean and green hydrogen gas as fuel, replacing conventional fossil fuels.
