Delhi’s winter haze is infamous for disrupting the air, railway and road traffic. With visibility dropping to near zero on a few days, life-threatening accidents spike during this season. Animals, on the other hand, seem to have a trick up their sleeves—they use sounds or visual cues to help them ‘see’ through low-visibility conditions. But what about fish? Can they navigate through turbid waters? Indeed, says a study by researchers at two Indian Institutes of Science Education and Research (IISERs), Mohali and Kolkata. The researchers have shown, for the first time, how zebrafish find food in turbid waters.

The Centre for Human Genetics, Bengaluru, is hosting the second edition of the Indo-Swiss Meeting Meeting on Evolutionary Biology, held in India this year. The meeting is jointly organised by the Indian Society of Evolutionary Biologists, Centre for Human Genetics, Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) and Swissnex India. The gathering brings together faculty and students from India and Switzerland. The three day meeting begins on the 12th of December and continues until the 14th.

The Indian monsoon, which sees much variability, has been crucial to the country's economy. It affects 42% of employed individuals in the country — farmers and those working in the agricultural sector. At times, a 'normal' monsoon brings enough rain to keep everyone happy, but sometimes, there is either a deluge or a drought. With recent meteorological advances, these variations can be predicted and recorded. But, how do we go back hundreds of years in time to understand the historical variability in Indian monsoon? Corals in the Red Sea may have answers, says a study by American researchers.

In a recent study, scientists from the Zoological Survey of India, Kolkata, have found a new species of earth-boring dung beetle in the Tawang district of Arunachal Pradesh during one of their field expeditions. Named after the district it was discovered in, Enoplotrupes tawangensis belongs to the family Geotrupidae.

Since 2012, six bridges have collapsed in Mumbai, killing 28 people and injuring hundreds. Often, news of flyovers and pedestrian bridges tumbling down have made it to the headlines across the country. Although durable materials like steel and concrete are used in today’s structures, poor quality of construction and lack of maintenance are often blamed for such catastrophes. Contrast this with the rock-solid centuries-old root bridges found in Meghalaya—many as old as 250 years and still growing strong—built without modern tools or design. Could the structure of these bridges unravel architectural clues for urban construction? In a recent study, researchers from Germany and the USA have tried to understand the morphology and structure of these root bridges, built out of the aerial roots of strangler figs, and that have endured floods, earthquakes, landslides and fires.

In a recent study, scientists have discovered two new species in the Western Ghats of Kerala, India. To date, this group of termites has been documented only in the Western Ghats of India. The termite species were named after Sri K.A. Dineshan and Sri. Manikandan Nair of the Zoological Survey of India, Kozhikode, who collected the samples from the field and contributed greatly to the entire faunal survey.

In a recent study, researchers from Anna University, Chennai, quantified the volume of virtual water trade in India. The study, published in the journal Groundwater for Sustainable Development, focussed on the trade exchange of popular crop and livestock products during the years 2006–2016.

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. 

Disgusting, annoying or beneficial? What would you call these pestering fruit flies that don’t miss an opportunity to sit on your favourite cut fruit or visit your kitchen a few times? Whatever you call them, did you know we owe a great deal of our knowledge on evolution to these pesky flies? Ever wondered what’s the lifestyle of Drosophila melanogaster, as they are scientifically called, within the four walls of a laboratory where they are experimented upon? Here is a sneak peek.

In a recent study, researchers from Sai Nath University, Ranchi, and Bharathiar University, Coimbatore, set out to quantify the impacts of natural radioactivity on the surrounding environment in the Nilgiris of Tamil Nadu. Their findings have been published in the Journal of Radiation Research and Applied Sciences.
