IISc scientists show how reading changes the way we see words

We all remember learning to read—at first, we were taught to read each letter or sound at a time laboriously. Eventually, we picked up reading entire words and sentences effortlessly. But, it is not yet clear as to what changes in our brain when we learn to read. In a recent study, researchers at the Indian Institute of Science, Bengaluru, have identified these changes in the brain changes that help in visually processing the words and helps us to read efficiently. The study was published in the journal Psychological Science and was funded by the Department of Biotechnology-Indian Institute of Science (IISc) Partnership Programme and the Wellcome Trust/DBT India Alliance.

Studies show vaccines have unexpected benefits — better cognition, school grades and child growth

The use of vaccination for preventing diseases has had the most profound effect on human health and quality of life. Despite this, anti-vaccination movements are gaining popularity in recent years, especially in high income countries with historically near universal vaccine coverage, like the USA. Consequently, cases of diseases like measles have seen a 30% rise globally. Vaccine hesitancy has been declared one of the top ten threats to global health by the WHO in 2019. In times like these, what if science showed some added benefits of vaccination besides the obvious? A recent set of studies by a team of international researchers, led by those at the Center for Disease Dynamics, Economics & Policy (CDDEP), Washington DC and New Delhi, have shown that vaccines can have other unintentional positive effects.

Learning to read has added benefits to the brain, study finds

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.

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.
