Approximately 75% of the emerging infectious diseases and 60% of all human diseases are zoonotic in nature, i.e. they are are caused due to the spread of infection between animals and humans. Leptospirosis, a zoonotic disease is a bacterial infection caused by the pathogen spirochetes and reports an estimated 1.03 million cases and 58,900 deaths each year.

India is one of the 17 megadiverse countries in the world and home to a vast expanse of natural habitats from evergreen forests to grasslands. These natural havens have over the past years faced many threats from humans, but the largest threat that Indian wildlife faces is poaching. How can these vast expanses be constantly monitored in order to protect our unique wildlife? Researchers and forest officials have come up with many ingenious methods using the latest technology to take action against this threat. From realtime videos accessible on smartphones to DNA analysis - read more about how our wildlife is being protected from poachers.
In the present time, with increasing demand for transportation fuels coupled with declining reserves of crude oil, scientific communities are forced to focus on renewable fuels.
Welding is a process that has been used to sculpt metal from the renaissance periods. Over the ages, it has become one of the key processes in making several consumable and artistic materials. Though there is mechanization in most industries, this field still has over 5 million people working in it.
Climate change and anthropogenic pressure are affecting natural environments world over. In this scenario how vulnerable are forests? If we keep growing at the rate we are growing now, what impact will it have on our forests in the years to come? Scientists from Indian Institute of Science and Wildlife Institute of India explore these far reaching questions in an Indian context. Their findings show that many forests are under considerable stress. The researchers say a perception change can help protect our forest.
Black holes are the celestial objects with such immense gravity that nothing can escape from them -- not even light!
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.
