Scientists from the Raman Research Institute, Bangalore point out the possible presence of exotic elements in our galactic halo.

On World Environment Day, June 5th the Hon'ble Minister for Environment, Forests and Climate Change, Science & Technology and Earth Sciences, Dr. Harsh Vardhan, pledged to do away with single-use plastics in his life. He also urged the citizens to take up green initiatives, while avoiding the use of plastics.

The clamour about the warming planet and the changing climate is growing louder by the day as we worry about the implications of greenhouse gases on the earth. But, did you know that our planet has seen many such ‘greenhouse periods’ in the past where the concentrations of greenhouse gases were significantly higher, resulting in higher temperatures?

Researchers from Indian Institute of Technology Bombay, Mumbai and Cornell University have been reviewing the models and simulations used to study interactions between humans and natural systems. Their study reveals the reason why early prediction of an approaching tipping point of an ecosystem still remains challenging.

The theme of World Environment Day 2018 is ‘Beat Plastic Pollution’. Take a look at the various efforts made by individuals and organisation to curb this pollution?

Researchers from Indian Institute of Science Education and Research (IISER) Thiruvananthapuram, Kerala and Institute of Microbial Technology, Chandigarh have developed a novel method to synthesize 2 dimensional nanosheets decorated with DNA molecule. The design strategy allows for an ultra dense array of DNA molecules to be grown on 2 D crystalline nanosheets.

ಈ ವರ್ಷದ ‘ವಿಶ್ವ ಪರಿಸರ ದಿನ’ದ ಅಂಗವಾಗಿ ‘‘ಪ್ಲಾಸ್ಟಿಕ್ಕಿನಿಂದ ಮಾಲಿನ್ಯ ತಡೆಗಟ್ಟೋಣ’’ ಎಂದು ವಿಶ್ವ ಸಂಸ್ಥೆ ಅಂತರರಾಷ್ಟ್ರೀಯ ಮಟ್ಟದಲ್ಲಿ ಘೋಷಿಸಿದೆ. ಪ್ಲಾಸ್ಟಿಕ್ ಇಂದು ನಮ್ಮ ಜೀವನದ ಅವಿಭಾಜ್ಯ ಅಂಗವಾಗಿದ್ದರೂ ಅದರ ಬಗ್ಗೆ ಸರಿಯಾದ ಅರಿವು ಅತ್ಯವಶ್ಯಕ. 

Researchers from Indian Institute of Technology Bombay, Mumbai are studying the strange phenomenon known as urban heat islands, which leads to a sharp temperature difference between urban and metropolitan areas and the surrounding rural areas, due to human activities.

ಪಶ್ಚಿಮ ಘಟ್ಟಗಳು ಜೀವ ವೈವಿಧ್ಯದಿಂದ ಸಮೃದ್ಧವಾಗಿರುವ ಪರಿಸರ ವ್ಯವಸ್ಥೆ; ಅದಕ್ಕೆ ಇದನ್ನು 'ಜೀವವೈವಿಧ್ಯತೆಯ ಹಾಟ್ಸ್ಪಾಟ್' ಎಂದು ವಿಜ್ಞಾನಿಗಳು ಘೋಷಿಸುತ್ತಾರೆ. ಆದರೆ ಈ ಘೋಷಣೆಯನ್ನು ಬೆಂಬಲಿಸಲು ಪುರಾವೆ ಹೇಗೆ ಸಿಗುತ್ತದೆ ಗೊತ್ತೇ? ಅದಕ್ಕೆ ಯಾವುದೇ ಒಂದು ಪರಿಸರ ವ್ಯವಸ್ಥೆಯಲ್ಲಿ ದೊರೆಯುವ ಮಾದರಿಗಳ ಸಂಗ್ರಹಣೆ ಮತ್ತು ವಿಶ್ಲೇಷಣೆಯ ಮೂಲಕ, ಜೀವವೈವಿಧ್ಯದ ಸಮೃದ್ಧಿಗೆ ಸಾಕ್ಷಿ ಒದಗಿಸುತ್ತಾರೆ.

How do scientists proclaim an ecosystem like the Western Ghats as an ‘biodiversity hotspot’ and push for its conservation? They do so by ‘ecological sampling’, a technique used to find diversity and abundance of animals and plants in a habitat.
