Ever wondered if natural surroundings give out subtle hints before going through landscape level transformations?
It is in the best interest of a tree to ensure that its seeds are dispersed to far off places where they can get good sunlight and nutrition to grow. This is carried out by the help of frugivores, who eat fruits and transport seeds in their gut. A recent study illustrates how irreplaceable elephants are as seed dispersers using computer simulation and three species of trees with large fruits. The study shows that in the absence of elephants no frugivores can disperse seeds as far or as efficiently.
Research at the Indian Institute of Science, Bengaluru and Vikram Sarabhai Space Centre, Thiruvananthapuram indicates that black carbon (BC) aerosol emissions from aircrafts could be impacting the stratospheric ozone layer. Aerosols are minute particles suspended in the atmosphere that interact with incoming and terrestrial radiation affecting the earth’s climate.
Why do we see certain species of animals in one place while they are absent in the neighbouring regions? How do species inhabit remote islands? Questions like these are central to our understanding of evolution and speciation. Exploring these question in a Sri Lankan context, scientists from National Centre for Biological sciences and University of Colombo studied how a two species of small passerine birds colonized the island nation. Through phenotypic and genotypic analysis they could show that not all Sri Lankan wildlife is a subset of Indian wildlife.
Hepatitis C Virus (HCV) affects 6-11 million people in India. Chronic HCV infection is the leading cause for liver-related deaths worldwide. In India, HCV infection was estimated to be responsible for 59,000 deaths in the year 2015. Moreover, untreated HCV infection could also lead to substantial economic burden.
Different parts of the country was inundated with floods this year, while other parts continue to face rainfall shortages, leading to drought situations. The culprit behind the disparity may be the sudden, extreme rainfall events we have been facing. Warming temperatures leading to extreme events may be affecting the overall rainfall the country receives says this new study.
Climate change is here and governments around the world are trying their best to stem its debilitating impacts. REDD+ (Reduce Emissions from Deforestation and forest Degradation), a programme to encourage the sustainable management of existing forests that take in large amounts of greenhouse gases, is a step in this direction.
Rabies is a fatal disease associated with dogs. However, it could well be spread by many animals -- both wild and pets. Today, on World Rabies Day, here is all you want to know about the disease and ways to prevent them. But if you thought it was a challenge, find out the truth about this and help make the world free of this deadly disease
For over a century, India has nutured a host of science and technology based institutions. We capture the timeline of these institutions as they were established.
Qissa-e-Sanjan, or the Story of Sanjan, records the epic tale of Parsi migration. It describes how a section of Zoroastrians left Iran to escape the Islamic conquest, and found India’s shores at Sanjan in Gujarat. Instead of a welcome they were presented with a full glass of milk, which symbolically suggested that there was no space for the newcomers.
