India, an emerging hotspot for antimicrobial resistance in farm animals, finds study

Antimicrobials, a class of drugs used in humans and animals to treat diseases caused by bacteria, fungi, and parasites serve as a proxy for good hygiene and make up for the poor husbandry practices in animal farms in low and middle-income countries around the world. However, this dereliction comes with a considerable cost wherein, the overuse of these drugs has led to these microbes developing resistance against the very same drugs used to kill them.  Antimicrobial resistance (AMR) in humans is linked to several animals, especially those that are raised for food. Despite this knowledge, it has received little attention in the world of animal science. A new study, published in the journal Science, has mapped the global trends of antimicrobial resistance in farm animals, with particular focus on developing countries, including India.

Study finds monkeys use gestures to communicate, just like apes.

Humans have evolved a complex system of communication expressed through language and primates are perhaps not far behind. Basic signals like facial expressions, gestures and vocalisations, used to share information, are used by humans and other primates. In a new study, researchers from the National Institute of Advanced Studies, Bengaluru, have investigated and compared gestural communication in wild bonnet macaques (Macaca radiata), to those in other apes.

Researchers design a synthetic antivenom to treat snake bites from the Indian krait

The Indian krait is undoubtedly the deadliest of all venomous snakes in the country, and possesses the most lethal concoction of poisons. In a study, a multi-institute research team, led by the Translational Health Science and Technology Institute (THSTI), Faridabad, have designed a synthetic antivenom with a nucleic acid aptamer which can diagnose Indian krait bites accurately and effectively.

Seeing climate change through the eyes of the Pikas

It’s getting tougher for the Royle’s pikas to survive in the Himalayas. But, these tiny, herbivores wouldn't move as they are particular about where they live. Restricted to rocky, mountainous terrains, they are now facing the wrath of rising temperatures and fluctuating environments. What would become of them in a few more decades? Can these fussy relatives of the rabbit find new homes and thrive? A new study by researchers from the Indian Institute of Science, Bengaluru and the Wildlife Institute of India, Dehradun tries to find out what the future holds for them, and that the findings are not good news.

Researchers design salt-tolerant varieties of Indian rice

In a country that predominantly depends on rain for irrigation, loss of crops due to disruptive weather continues to be a source of distress to farmers, and approaches to make crops tolerant to the vagaries of weather are necessary. In a recent study, researchers have shown that, by modifying particular genes, rice plants can be kept alive through periods of acute salinity in their water supply.
