Polaris Dawn, a private space mission has set a new record for the highest orbit reached by humans since NASA‘s Apollo programme. On 10th September 2024, the four-member Polaris Dawn crew aboard SpaceX‘s Dragon spacecraft Resilience achieved an apogee of 1,400.7 kilometres. This surpasses the 1966 Gemini 11 mission’s altitude of 1,373 kilometres, marking the

Indian researchers at the Institute of Nano Science and Technology (INST) in Mohali, led by Dr. Bhanu Prakash, have developed a new technique to address chromium contamination in wastewater. This technique employs sunlight as a catalyst in combination with microfluidic technology to convert toxic hexavalent chromium [Cr(VI)] into the less harmful trivalent chromium [Cr(III)]. This
