Chemogenetics is a technique that uses chemicals to understand how neurons are activated. It manipulates genes to place the neurons under the control of special receptors called DREADDS. Short for Designer Receptors Activated by Designer Drugs, these receptors only bind to an inert chemical called Clozapine-N-Oxide (CNO). In a recent study, researchers from the Tata Institute of Fundamental Research (TIFR), Mumbai, and Jawaharlal Nehru Center for Advanced Scientific Research (JNCASR), Bengaluru, point out specific flaws in this technique.

An international study, led by researchers from the USA, which also included researchers from India, have designed a point-of-care testing approach for individuals suffering from TB. The study, published in the journal Science Translational Medicine and supported in part by the Bill and Melinda Gates Foundation, proposes a rapid, cost-effective, and readily accessible triage test kit that can be used at the site of patient care.

The impacts of climate change on coastal areas are severe than inland as they are vulnerable to flooding and extreme weather phenomena like cyclones, tornadoes etc. As the climate crisis deepens, a quarter of India's population, who live along the coasts, have another issue to worry about – availability of freshwater. Due to unchecked pumping of groundwater for daily use and rainfall variation, freshwater sources are being depleted. Besides, saltwater from the sea is unwittingly finding its way into local aquifers through a process called seawater intrusion. Although many independent studies, conducted at different locations, have observed depletion in freshwater sources along India's coasts, there is no comprehensive study yet. Now, researchers at Anna University, Chennai, have tried to address the extent of seawater intrusion in the Indian coastal regions in a study published in journal Environmental Science and Pollution Research. The study was funded by the National Centre for Earth Sciences Studies, Earth System Science Organisation, and the Ministry of Earth Sciences.

How many bird calls can you recognise? Crows and pigeons, for sure! But have you ever come across an app that can recognise bird calls for you? With apps like eBird and India Biodiversity Portal, identifying and collecting data has become an activity that not just researchers can take part in. Rather, these technological advancements provide a push to scientific research as a whole! A mini-symposium was organised in IISER Mohali to discuss just that.
