Real Time Train Information System (RTIS) Project: The Indian Railways is collaborating with Indian Space Research Organization (ISRO) under the Real Time Train Information System (RTIS) project. RTIS devices that use satellite imagery are being installed on the trains to automatically acquire its “movement timing at the stations, including that of arrival and departure or […]

Megha-Tropiques-1: The Indian Space Research Organisation (ISRO) will be undertaking a challenging experiment of a controlled re-entry of the decommissioned Megha-Tropiques-1 (MT1) satellite on March 7, 2023. Megha-Tropiques is an Indo-French Joint Satellite Mission for studying the water cycle and energy exchanges in the tropics. Objective is to understand the life cycle of convective systems […]

Organoid Intelligence: Scientists at Johns Hopkins University (JHU) recently outlined a potentially revolutionary new area of research called “organoid intelligence”, which aims to create “biocomputers”. Bio computers are computing devices that use biological components such as DNA, proteins, and cells to perform computational tasks. Biocomputers use the properties of biological systems to perform computations, such […]

Sagittarius A*: Astronomers have recently discovered a young star in the violent and tortured environment around the supermassive black hole at the core of the Milky Way galaxy, known as Sagittarius A* (Sgr A*). Sagittarius A* (Sgr A*)  is a supermassive black hole located at the center of the Milky Way Galaxy. It is located […]

DNA Vaccine Against Dengue: India’s first prospective DNA vaccine against dengue is under clinical trials. The DNA vaccine has been in development since 2019 by scientists from the National Centre for Biological Sciences (NCBS), Bengaluru, in collaboration with nine institutions in India, Africa, and the US. DNA vaccines use engineered DNA to induce an immunologic […]

NASA’s Imaging X-ray Polarimetry Explorer (IXPE): Researchers studied a supernova explosion that occurred over 450 years ago using NASA’s Imaging X-ray Polarimetry Explorer (IXPE). The explosion, called Tycho, was visible to people on Earth in 1572, and the shock wave from the blast is still propagating through the cosmos. Tycho is classified as a Type […]
