AI-powered deepfakes rise in 2023; concerns of its impact on privacy

From politics to films and even war, the year 2023 has demonstrated that not everything one sees or hears on the internet may be real. With the ever-evolving Artificial Intelligence technology rapidly becoming a part of people's lives, a sharp rise in deepfakes has raised concerns in the country about its potential to influence electoral politics, especially during the Lok Sabha polls slated to be held next year. Deepfakes are manipulated videos or other digital representations that use artificial intelligence to create cogent videos or audio of individuals they never did or said, posing a risk of spreading misinformation and damaging their reputation. According to the '2023 State of Deepfakes Report' by 'Home Security Heroes' -- a US-based web security services company -- deepfake videos saw a five-times increase since 2019. In 2023, India witnessed scores of troubling instances related to deepfake videos, like the one involving actor Rashmika Mandanna, whose face was superimposed

IIT-Mandi finds cost-effective alternative to metal 3D printing tech

Researchers from IIT-Mandi have found that the extrusion-based metal additive manufacturing process stands out as the most superior and cost-effective method in comparison to other approaches in metal 3D printing. According to officials, metal additive manufacturing (metal AM) utilises fine metal powders to construct robust, intricate components through computer-aided design (CAD) programmes or 3D scanning. "This layer-by-layer manufacturing process offers flexibility in designing complex structures, finding applications in diverse industries such as aerospace, automotive, spare parts, heat sinks, biomedical devices, and construction materials," said Naveen Kumar Bankapalli, Research Scholar, the Indian Institute of Technology (IIT), Mandi. "This analysis empowers individuals, industries, or researchers to independently develop and implement this technology, facilitating cost-effective mass production of metal parts," he said. Particularly noteworthy for aerospace applications due

IIT Guwahati discovers modified graphene oxide's potential in medicine

Researchers at the Indian Institute of Technology (IIT) Guwahati have developed cost-effective experiments for modifying graphene oxide that can be used by other academic institutions to train personnel needed for cutting-edge projects in semiconductors, nanoelectronics, healthcare and quantum technologies. A team led by Rajiv K Kar, assistant professor, at the Jyoti and Bhupat Mehta School of Health Sciences and Technology in IIT-Guwahati, have made these important discoveries regarding the use of modified graphene oxide for biomedical applications, a release said on Tuesday. Graphene is an exceptionally strong material and possesses outstanding electrical and thermal conductivity. Its oxidised form, called Graphene Oxide (GO), offers a large surface area and low cytotoxicity, making it suitable for medical applications. GO can be further engineered through defects, doping and functional modifications, which enhance its optical and electrical properties for improved biomedical ...
