A new study conducted by scientists from the Indian Institute of Technology Bombay (IIT Bombay), Mumbai published in NPJ Systems Biology and Applications, has shed light on the process of speciation, meaning the formation of new species, in the absence of geographic barriers. Traditionally, it is believed that speciation largely occurs when populations of a…

Viruses infect plants, animals, and humans. A virus’ spread from animals to humans could unleash pandemics like COVID-19 — significant public health crises with considerable economic and social fallout. To nip such infections in the bud, public health researchers have advocated the ‘One Health’ approach: monitoring and protecting plant, animal, environment, and human health in…

Questions: 1. Scientists first synthesised the element promethium in 1945 even though the Czech chemist X had predicted its existence 43 years earlier. X was in fact renowned for his study of rare-earth elements. Name X. 2. In the earth’s environment, promethium is produced in two ways: when europium-151, an already very rare isotope, breaks…

Microcephaly is a condition in which a baby’s head is much smaller than normal. Most children with microcephaly also have a small brain, poor motor function, poor speech, and abnormal facial features, and are intellectually disabled. Researchers believe the roots of the condition lie in the peak phase of brain development in the embryo — when…
