Tetrapod-shaped nanoparticles could make plastics easier to process, finds IIT study
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 their versatility to long molecular chains called polymers, which make them moldable and stretchable. However, many synthetic plastics...

Hypoxia rewires membrane lipids, drives pancreatic cells to move: IIT-Bombay study
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...

How are passengers able to access the Internet on aeroplanes?
Passenger Internet on aeroplanes used to be rare in the 2010s but has become almost commonplace today. On most flights, the basic idea is that the whole aeroplane is treated like a flying Wi-Fi router that connects to the rest of the Internet through a long backhaul link. This means your phone or laptop never...

Indian researchers reveal novel mutation that causes rare condition among consanguineous children
A recent paper in the peer-reviewed journal Clinical Dysmorphology has presented the first detailed case report of a new kind of gene mutation in a child, with a rare condition – pseudo-TORCH Syndrome Type 2. Using exome sequencing, a genetic test that analyses the protein coding regions of the DNA, researchers have identified a novel...

Where does road dust settle in India’s efforts to clean its air?
Road dust mainly comprises PM₁₀ and coarse particles and forms a large share of the air we breathe. With the National Clean Air Programme (NCAP) aiming for a 40% reduction in PM₁₀ by 2025-2026, reducing road dust is an urgent priority. This is reinforced by source apportionment studies across 17 non-attainment cities that have found...
