How does the Gaganyaan’s life-support system operate?

The Environmental Control and Life Support System (ECLSS) replicates the earth’s atmosphere in earth orbit by managing air, water, temperature, and waste. In short-term space missions, all supplies are carried from the earth and waste is stored for disposal later. Long-duration missions recycle the waste back into useful resources like breathable air and clean water....

Is a heatwave really a wave of heat?

A: A heatwave is not like a wave or pulse of heat travelling through the air. The name probably comes from the way a heatwave feels, as something that spreads, surges, and overwhelms before subsiding. Some meteorologists prefer the team “heat event” instead. For example, in April and May, the sun is almost directly overhead...

Understanding albinism

A condition which affects not just humans, but also animals and plants, albinism is a result of little or no production of melanin, a natural pigment responsible for determining the colour of human skin, hair, and eyes. Let’s explore… Understanding the biology On average, one in 17,000 people is affected by albinism worldwide. This often...

New worm-eating snake named after Mizoram herpetologist

GUWAHATI The jungles of Mizoram and neighbouring Myanmar have yielded a new-to-science snake that relishes worms and prefers to stay underground. The snake, Trachischium lalremsangai, has been described in the international Herpetozoa journal of the Austrian Herpetological Society by a team of four scientists from two continents. They are Virender K. Bhardwaj, Amit K. Bal, and Chhangte L....

The rise of epidemiology as a discipline and the birth of hypertension as a disease

In February 1945, Franklin Delano Roosevelt, then U.S. president, arrived at the Yalta Conference to negotiate the post-war future of Europe alongside Winston Churchill and Joseph Stalin. The American president appeared visibly exhausted, lethargic and physically frail. Behind those images lay a silent medical crisis. Roosevelt’s blood pressure had reached around 260/150 mm Hg before...

BITS Pilani Hyderabad researchers develop graphene electrode for improved supercapacitor performance

Researchers at the BITS Pilani Hyderabad Campus have developed a new graphene-based electrode that could improve the performance and lifespan of supercapacitors, an emerging energy storage technology used in portable electronics, wearable devices, and microelectronic systems. The work was carried out by scientists at the MEMS, Microfluidics and Nanoelectronics (MMNE) Lab and published recently in...

What is the Zwan-Wolf effect at Mars?

A: The solar wind is a stream of charged particles flowing outwards from the sun. As the solar wind nears the magnetic field of a planet, it becomes compressed near the magnetic boundaries. This creates a difference in pressure, or pressure gradient, that squeezes the charged particles along the magnetic field, away from the stream....

Improving efficiency of fertilizer use in India

The ongoing war in West Asia and the rising costs of fuel and fertilizers give India an opportunity to enhance fertilizer use efficiency and moderate demand. India produces 80% of its urea requirement domestically and imports the rest while also boosting domestic production capacities to become fully self-reliant. But India’s urea industry relies too heavily...
