In a recent study, researchers from the Indian Institute of Technology (ISM) Dhanbad have developed a blood glucose sensor to monitor blood sugar using light. It can measure a wide range of values of blood glucose, between 10 to 200 mg/dl, say the researchers. The average blood sugar level in healthy adults when fasting is between 70 to 120 mg/dl.
Researchers have identified urban sewage as a critical hotspot for the evolution and spread of drug-resistant bacteria, highlighting an urgent need for nationwide wastewater monitoring to prevent future health crises.
