According to the National Tiger Estimation survey, the number of tigers has surged to 2967, indicating a doubling of tiger numbers since the first survey conducted in 2006 under a revised monitoring methodology. Although this change may sound exciting to the layperson, some scientists have flagged concerns about accepting these claimed changes in tiger numbers. In a recent study, published in the journal Conservation Science and Practice, researchers from India and Norway refer to important mathematical, statistical and ecological principles and highlight how India’s tiger survey results deviate from these principles.

In a country like India, dealing with disability can be a challenge on its own. A strong social stigma and discrimination can play havoc in one’s life leading to suicidal thoughts and depression. In a recent study, researchers have tried to understand how people with hearing loss cope with their life and if assistive technologies like hearing aids are making their lives better. By interacting with people in Kannada, a local language, the study has unearthed some of the often overlooked emotions and challenges faced by people using hearing aids to deal with their hearing loss.
