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.

Sometime in the middle of October each year, the Bomrr clan in Nagaland rush to the caves in Mimi village. With a good stock of burning firewood, men and women are ready for the bat harvest festival—an annual ritual where anywhere between 7,000 to 25,000 bats are suffocated or smashed to their deaths. These bats, the clan believes, have medicinal properties and can cure diseases like diarrhoea and body ache, and increase vigour. Now, a new study has shown that these bats, rather than being a cure to diseases, carry deadly filoviruses that could infect humans.

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. 

Prof R B Sunoj of the Department of Chemistry of the Indian Institute of Technology Bombay has received the 2019 Shanti Swarup Bhatnagar Prize by Council of Scientific and Industrial Research (CSIR). The prize recognizes his outstanding contributions for providing molecular level insights on organic reaction mechanisms.

We have all heard of the Indus Valley Civilisation.It is well known for its granaries, drainage systems and systematically planned cities like Harappa and Mohenjodaro. However, not much is known about its rise and fall; although there are various theories. In a pair of new studies published in the journals Science and Cell, a consortium of international researchers, including those from India, have tried to decipher the origins of present-day Central and South Asian people. They have used recent advances in genetics to extract and analyse genetic material (DNA) from the remains of several ancient populations, including people from the Indus Valley Civilisation.

Study shows almost 40% South Asians and 60% Sub-saharan Africans cannot afford the EAT-Lancet diet.

Researchers estimate that half of these deaths, resulting in India and China, can be prevented.

An international team of scientists from China, the USA, the UK, Hungary, Austria, Germany and India, have carried out observations of the Sun using the Goode Solar Telescope (GST) at the Big Bear Solar Observatory in the USA. Their study is published in the journal Science.

Dr Siddhesh Kamat, Assistant Professor at the Indian Institute of Science Education and Research (IISER) Pune, is among the 27 recipients of the European Molecular Biology Organization's (EMBO) Young Investigators Grant. EMBO is an organization headquartered in Heidelberg, Germany, and promotes international collaboration among life sciences researchers.

We all know that the geometric object of minimal surface area amongst all shapes with a fixed volume is the round ball, whose boundary is spherical. Water blobs try to minimise surface area and curl into spherical droplets. The physical problem of surface-area minimisation is thus quite well understood. What about the opposite problem of surface-area maximisation? Does the problem even make sense? Indeed it does. Trees try to maximise surface area to get the most of sunlight through their leaves.
