IIT Palakkad study shows how different indices used to predict drought combined with effects fof climate change can lead to different climate predictions for the future
Technology has revolutionised medicine in the past century. We now have imaging methodologies like X-rays, Computed Tomography (CT) scans and Magnetic Resonance Imaging (MRI) allowing us a look inside the body without cutting it open. Nanotechnology seems poised to write the next chapter of this revolution, with various applications in biomedical imaging, diagnosis and effective treatment of diseases. In yet another advancement in this direction, an interdisciplinary team of scientists from Materials Engineering Department and Department of Microbiology and Cell Biology at the Indian Institute of Science (IISc), Bangalore, have synthesised iron nanoparticles without any oxide cover that could be used to enhance the sensitivity of MRI by producing images with better contrast. They have also demonstrated the potential application of this research in the targeted delivery of medicines and other biological molecules to specific organs in the body.
