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.

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).
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.
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!
In a new study, researchers from the Indian Institute of Science, have found that ten confined water molecules play a significant role in keeping the insulin molecules together. In their findings published in the Journal of Physical Chemistry, the researchers have used computer models to study how water molecules help in stabilising the structure of insulin for storage in our body.
Study from the Indian Institute of Technology, Bombay, explores how consumer choice affects rating labels of electrical appllicances like air conditioners. They find that Indian consumers are willing to pay more for air conditioners iwth higher energy efficiency.
The Biotechnology Industry Research Assistance Council (BIRAC) celebrated its 6th Foundation Day on Tuesday, March 20th, at the India Habitat centre in New Delhi. This year, the theme for the Foundation Day celebration was ‘Sustaining Innovation: A market driven pathway’. The event saw a participation from large number of dignitaries from the industry and academia, public and private sector, policy makers and national and international organizations.
Scientists from the Indian Institute of Science, Bangalore, study how speech recognition software can be improved by modelling it to be more like the brain, such that it works well even in the presence of background noise.
Clean drinking water is an essential prerequisite for good health. In a country like India, where 21% of communicable diseases spread through unsafe water, and more than 500 children under the age of five die each day from diarrhoea, the accessibility to clean drinking water is paramount. Researchers from the CSIR-Indian Institute of Toxicology Research, have developed a frugal water purification system, Oneer, to help overcome our water woes.
