CLRI’s biocatalyst cuts effluent discharge during leather processing

A novel biocatalyst developed by researchers at CLRI, Chennai speeds up the leather processing time at the pre-tanning stage, cuts chromium usage, and achieves three-fold reduction in water usage thus reducing waste discharge. A novel amylase-based biocatalyst developed by researchers at the Central Leather Research Institute (CSIR-CLRI), Chennai helps in the processing leather in an … Continue reading CLRI’s biocatalyst cuts effluent discharge during leather processing

IIT Jodhpur fabricates a highly sensitive hydrogen sensor

A research team from IIT Jodhpur and IIT Hyderabad have together fabricated a sensor that can detect hydrogen gas even when present at extremely low concentration of 1 ppm. The sensitivity is 30% at 1 ppm hydrogen concentration and 74% at 100 ppm concentration. A sensor that can detect hydrogen gas even when present at … Continue reading IIT Jodhpur fabricates a highly sensitive hydrogen sensor

Irrigation, agriculture shift rainfall to northwest India, IIT Bombay finds

IIT Bombay researchers have found the reason why the summer monsoon rainfall has shifted towards northwest India and intensification of extreme rainfall is seen over central India during the month of September. They have developed a land-surface model that takes into account the Indian conditions. For the first time, researchers from the Indian Institute of … Continue reading Irrigation, agriculture shift rainfall to northwest India, IIT Bombay finds

Toxic mercury in fish increases with ocean warming, overfishing

Based on data and modelling, researchers from Harvard University have found that the amount of toxic mercury (methylmercury) in fish higher in the food chain can change due to two reasons — ocean warming and dietary shifts due to overfishing by humans. Despite a decrease in seawater concentration of methylmercury since the late 1990s, the … Continue reading Toxic mercury in fish increases with ocean warming, overfishing

IISER Mohali finds zebrafish use landmarks for navigation

IISER Mohali researchers have found that zebrafish did overcome the challenges posed by reduced visibility in turbid waters after a month of acclimatisation. They show zebrafish use visual cues to navigate to foraging sites especially when turbidity is high and visibility is low. Turbid to extremely turbid water conditions are quite common in areas where … Continue reading IISER Mohali finds zebrafish use landmarks for navigation

TIFR desalinates seawater without using electricity

TIFR researchers have produced gold nanoparticles that can absorb sunlight over the entire visible region and even the near infrared light. They used such gold nanoparticles to absorb energy from sunlight to be able to desalinate seawater to produce drinking water. The gold nanoparticles can also be used for converting carbon dioxide to methane more … Continue reading TIFR desalinates seawater without using electricity

IITM Pune develops model to predict heat waves three weeks in advance

Researchers at Pune's Indian Institute of Tropical Meteorology have developed a model that can predict heat waves three weeks in advance. It can predict the date of onset, duration and demise of the forthcoming spell of heat waves, with a small spatial and temporal error.  The prediction system has been successfully transferred to the Indian … Continue reading IITM Pune develops model to predict heat waves three weeks in advance

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

Scientists vote to recognise Anthropocene as a new epoch

A 34-member panel of the Anthropocene Working Group voted to designate Anthropocene as the new geologic epoch. The vote signals the end of the Holocene Epoch which began 11,700 years ago. The focus is now on identifying a definitive geologic marker or golden spike to signal the beginning of the Anthropocene Epoch. On May 21, … Continue reading Scientists vote to recognise Anthropocene as a new epoch

Surveillance from the sky using RISAT-2B satellite

RISAT-2B satellite launched on May 22 will use microwave radiation for crop monitoring, forestry and flood mapping. The satellite can image during day and night and under almost all weather conditions including cloud cover. It can detect objects with dimensions of as little as a metre, making it ideal for military surveillance. With the successful … Continue reading Surveillance from the sky using RISAT-2B satellite
