Silver nanoparticles are nanoparticles of silver whose size varies from 1 nm to 100 nm. They are commonly used in the manufacture of about 200 consumer products, including clothing and cosmetics. While their antibacterial properties are hailed, reckless dumping of these nanoparticles is reported to pollute water and soil due to formation of toxins like silver sulfide.

On the 26th of March, 2018, Prof. K VijayRaghavan, ex-Secretary, Department of Biotechnology (DBT), and ex-Director of the National Centre for Biological Sciences (NCBS), was appointed the Principal Scientific Adviser to the Government of India. He succeeds Dr. R. Chidambaram and is expected to assume the office shortly.

After the devastating Tsunami in 2004, various measures have been taken by the Government of India to be more prepared in the future. Indian Tsunami Early Warning System (ITEWS) is one such effort undertaken by  Indian National Centre for Ocean Information Services (INCOIS).

Latest research from the Indian Institute of Science, Bangalore, demonstrates how chemical interactions take place between wasps and fig trees and the tussle between pollinating and non pollinating wasps.

Microbial Fuel Cells (MFCs) are bio-electrochemical devices that use the power of respiring microbes to convert organic matter into electrical energy. Thus, they can help treat wastewater and also generate electricity. Realising the vast potential these cells have, scientists are finding ways to improve their performance and efficiency.

Shola grasslands are a unique habitats of the Western ghats that are under threat from many factors. In a recent collaborative study, scientists explore what are the major threats to this habitat.

Doing our dirty jobs of clearing animal carcass for generations, extraordinary scavenging birds of prey, the vultures, deserve our gratitude and attention. Associated with goddesses in Egyptian mythology and revered hero in Indian mythology as Jatayu who sacrificed himself to save Sita, and once commonly seen; today, most species of vultures face extinction worldwide. Four out of nine species of vulture in India are critically endangered; it is now crucial to understand this often overlooked ecologically important bird.

In a new study, researchers have developed a low-cost and eco-friendly method to extract gold from electronic waste using the leaves of the plant Lagerstroemia speciosa, commonly called the Pride of India. They have applied the principle of biosorption—the ability of biological materials in an aqueous solution to bind with heavy metals—to extract gold from wastewater.

Power cuts in many parts of the country are so commonplace that we have learnt to accept and adapt to the erratic supply, no matter how frustrating. With summer rearing its fiery head, the threat of sitting in sweltering heat without fans or air-conditioners is a nightmare. A recent UN report found that 10% of people from developing countries have no access to electricity!
