The laws of electromagnetism at the scale of a few atoms

Researchers have demonstrated the reciprocal relationship of electricity and magnetism over a thin magnetic film. 

Physicists discovered the relationship between electricity and magnetism more than a century ago. The intricate relationship between these entities, previously thought to be separate, currently goes by the name „electromagnetism‟. It largely governs the world in which we live. From large power grids to fans in our rooms to electronic gadgets, everything runs on these well-understood principles.

Merging memory and computing in nanoscale devices for efficient computation

Scientists have devised a novel approach to combine memory and computation units 

Modern computers carry out computations — also called ‘logical operations’ — on massive amounts of data that are stored in specialised memory devices. The computing blocks need to exchange significant amounts of data with Random Access Memory, or RAM, a type of temporary memory. Over the years, various applications that search and process the appropriate data from memory devices have increasingly demanded faster computations.

Supplying water through tankers to urban India

Researchers develop a realistic framework for planning and scheduling water tanker movement in cities

It is not just a shortfall of adequate water sources that is responsible for the water woes in our cities. Many parts of the ever-growing urban areas are still waiting for piped water, and citizens and city water supply boards alike are dependent on tankers to fetch water to cope with the erratic supply. For instance, the Delhi Jal Board has a fleet of around 800 tankers providing water to its people across different parts of the city.

How Do Taro Leaves Repel Water?

Researchers study the structure of taro leaves to make water-repellent material

The leaves of taro plants are a familiar ingredient in many regional delicacies across India. Featuring in dishes like alu wadi and pathrode, the heart-shaped leaves of this plant have an interesting quality — they are hydrophobic. Liquids that land on their surface do not wet the leaves but instead roll off them.
