In the course of human evolution, our ability to read is a relatively newly acquired trait. Hence, it is highly unlikely that a region of the brain could have evolved specifically for reading, unlike much more ancient functions like seeing or hearing. But, how is it that we are capable of this unique feat that involves recognising words and interpreting their meaning? Reading requires the coordinated functions of several regions in the brain, particularly associated with visual sensory processing. In a recent study, an international team of researchers investigated the effects of reading on the visual system in the brain.This study was published in the journal Science Advances.

During the years 2018-2019, India witnessed a few ‘Kisan Long Marches’, where thousands of farmers took to the streets. They marched against state and central governments to alleviate their suffering. Their demands included loan waivers, proper land ownership rights, access to insurance and other welfare schemes, and obtaining a justified price for their crops. The Indian farming community is facing a crisis and farmer suicides are increasing by the day. Does the country’s social and caste structure add to these woes of the farming community? A recent study by researchers has found some insights. The study, published in the journal PLOS One, explored if caste of the farmers played a role in them having access to agriculture-related information. 

The city of Delhi has been consistently ranked as one of the world's most polluted cities. As the monsoon ends, haze sets in, with Deepawali around the corner, bringing the entire city to a standstill with low visibility. Besides vehicular emissions, smoke from diesel generators and construction dust, a significant contributor to this problem is the practice of crop residue burning by farmers in Punjab and Haryana. A recent study, published in the journal Nature Sustainability, suggests that groundwater conservation policies, adopted by Punjab and Haryana, have changed the patterns of rice production. These policies, the researchers argue, have led to the concentration of crop residue burning into a narrower period, later in the season.

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. 

Researchers compare how the Greek and Indian mathematicians measured the surface area of a sphere.

The differences in a child’s response to visual changes could point beyond how the brain functions, how it remembers its surroundings and detects changes. It could also indicate the parents education level and their economic status, says a new study. The study, published in the journal Developmental Science, looks into how children from disadvantaged backgrounds perceive visual changes.

India, the world’s capital of diabetes, has an escalating diabetes epidemic. Diabetes, a non-communicable disease, affects about 8.7% Indians today, and this number is predicted to hit 70 million by 2025 and 80 million by 2030. Although the exact reasons for this rapid rise in diabetes in the country are not yet clear, experts blame it on multiple factors. In a recent study, researchers from the USA, Germany and India have investigated the status of diabetic care among Indian adults. The findings, published in the journal BMC Medicine, present a grim picture of diabetes management in different states and socio-demographic groups in India.

Visceral leishmaniasis, or kala-azar, is an insidious disease that affects thousands of people every year. This illness can be fatal, if not diagnosed and treated on time. However, despite best efforts, India still lags behind in eliminating this disease completely. A recent study published in the journal PLOS Neglected Tropical Diseases has investigated the factors that lead to the delayed diagnosis and treatment of kala-azar.

Researchers from Sankara Nethralaya, Chennai, SASTRA University, Thanjavur and Elite School of Optometry, Chennai have studied how the environmental factors of a classroom affect a student’s clarity of vision.

Bengaluru’s decreasing tree cover and expanding concrete jungle in recent decades paints a grim picture of the city’s biodiversity. The tales of sparrows nesting on the roofs, parakeets pecking on the juiciest fruit in the backyard tree or the myriad coloured butterflies dancing in the garden are now fragments of imagination! So where have all the birds, animals and insects gone?
