Recognising Anthropocene as an epoch is a caution to humanity

The overwhelming vote by the Anthropocene Working Group to recognise Anthropocene as a new epoch is a grim reminder to humanity that failure to end destructive activities will irrevocably change the face of the earth and make it uninhabitable. The pervasive and long-lasting signatures of modern human activity on earth have been so striking, that … Continue reading Recognising Anthropocene as an epoch is a caution to humanity

Podcast: Increasing the cellular uptake of fluorescent probe using iodine

Prof. Govindasamy Mugesh explains how the the cellular uptake of fluorescent probe naphthalimide was drastically improved (from 5-8% to up to 98%) by substituting two of its hydrogen atoms with iodine. The iodine atom forms a halogen bond with the MCT8 receptor that ferries the molecule across the membrane. The receptor is known to transport thyroxine, which is a … Continue reading Podcast: Increasing the cellular uptake of fluorescent probe using iodine

IISc team uses iodine to increase cellular uptake of fluorescent probe

IISc researchers have drastically improved (up to 98%) the cellular uptake of fluorescent probe naphthalimide by substituting two of its hydrogen atoms with iodine. The iodine atom forms a halogen bond with the MCT8 receptor that ferries the molecule across the cell membrane. The probe molecule with iodine will also help in studying the uptake of thyroid hormone. By … Continue reading IISc team uses iodine to increase cellular uptake of fluorescent probe

Editorial: Transparency by AERB at any cost

The shutdown of the 220 MW Unit-1 of the Kakrapar Atomic Power Station located in Gujarat’s Surat district following leakage of heavy water used to cool the nuclear reactor, on March 11, the fifth anniversary of the Fukushima Daiichi nuclear plant disaster in Japan, is at once a reminder of the inherent risks associated with … Continue reading Editorial: Transparency by AERB at any cost

Why Kolar gold mine never became a repository

Published in The Hindu on November 29, 2012 The search for a possible final resting place or a deep geological repository for storing the high level radioactive waste generated during reprocessing of spent fuel has been going on for the past few decades and may well continue for some more time. The defunct Kolar gold … Continue reading Why Kolar gold mine never became a repository

Editorial: After sayonara, second thoughts

Published in The Hindu on September 25, 2012 Now that the dust has settled, the Japanese government’s failure formally to approve a cabinet panel proposal to phase out nuclear energy by 2040 is being seized upon by nuclear industry advocates intent on pressing for the deadline’s eventual abandonment. The government’s Energy and Environment Council — … Continue reading Editorial: After sayonara, second thoughts

Editorial: Sayonara nuclear power

Published in The Hindu on September 22, 2012 The much needed big push towards low-cost, highly-efficient, cutting-edge renewable energy technologies was lacking till recently. Even the compulsion to cut down carbon dioxide emission levels by 2020 failed to overcome the inertia. But the landscape has squarely and dramatically changed following the 9 magnitude earthquake and … Continue reading Editorial: Sayonara nuclear power

Editorial: Price of collusion

Published in The Hindu on July 19, 2012 The recently released report of the Fukushima Nuclear Accident Independent Investigation Commission provides official confirmation of what has been common knowledge since the March 11, 2011 disaster: that the Tokyo Electric Power Company (TEPCO) cared little for safety right from the point of choosing sites for its … Continue reading Editorial: Price of collusion

Consuming plutonium for producing energy is the superior option: Anil Kakodkar

Published in The Hindu on May 10, 2012 A paper published today (May 10) in Nature states that the process of converting plutonium to MOX (mixed oxide fuel containing uranium and reprocessed plutonium) for use in reactors is costly and risky. Using in fast breeder reactors does not address the central issue of reducing the … Continue reading Consuming plutonium for producing energy is the superior option: Anil Kakodkar
