The location of ‘Krishnan’ crater and nearby features | Photo Credit: Special arrangement A 3.5 billion-old crater on Mars will henceforth be known after M.S. Krishnan, the pioneering Indian geologist. The International Astronomical Union (IAU) has approved it and several other names for Martian landforms proposed by two Kerala-based researchers. Apart from ‘Krishnan,’ the IAU…

Previous work had already shown that channel state information (CSI) from WiFi signals can be used to identify people in a room but CSI is harder to obtain and needs specialised hardware and firmware. | Photo Credit: Paul Hanaoka/Unsplash Modern WiFi standards have a feature called beamforming that helps routers push signals more efficiently towards…
For representative purposes. | Photo Credit: Getty Images Research fraud is a global problem and has become worse due to the growing use of Artificial Intelligence (AI). The problem is even more acute in India’s higher education sector where both the number of journal publications and retractions are growing rapidly. However, journal retractions do not…

An image of concrete tetrapods used as wave breakers to prevent beach erosion. | Photo Credit: Special Arrangement A collaborative study by researchers from three Indian Institutes of Technology (IITs) has found that adding tetrapod-shaped nanoparticles to certain synthetic plastics can significantly reduce their viscosity, making them easier and less energy-intensive to process. Plastics owe…

Pancreatic cancers are aggressive and deadly, with high rates of metastasis and poor prognosis. The tumour environment is also hypoxic: the cells rapidly divide and thrive in very low oxygen conditions. Now, IIT-Bombay researchers have shown that the hypoxia ends up enhancing the cells’ metastatic behavior. By affecting the cells’ plasma membrane lipids, hypoxic conditions…
