Researchers have shown a loophole in the no-cloning theorem by creating perfect copies using ideas from information theory. The protocol is illustrated here. | Photo Credit: Image created with Sonnet 4.6 Quantum physics has a rule called the no-cloning theorem that prevents you from making a perfect copy of an unknown quantum state. It has…

India’s long wait for a dengue vaccine may finally be coming to an end. Takeda’s tetravalent dengue vaccine, TAK-003 (called ‘Qdenga’), recently received clearance from the Subject Expert Committee (SEC) under the Drugs Controller General of India (DCGI) for use among individuals aged 4 to 60 years. This marks a significant milestone in the country’s…

Scientists have shown that helium atoms can be entangled through their movement. Representative illustration. | Photo Credit: Getty Images Scientists have shown that helium atoms can be entangled through their movement. A team from Australia and the U.S. collided clouds of helium atoms together to create pairs that shared a single quantum state. The achievement…
Throughout human history, the sky symbolised freedom — vast, open, untouched. Today, that no longer holds. The earth’s orbital environment has become crowded, fragile, and vulnerable, threatened by what is today evidently a failure of governance rather than just of engineering. The language of space sustainability has grown familiar in international forums and policy documents….

Parkinson’s disease affects more than 10 million people worldwide. A patient struggles to perform coordinated movement, requiring conscious effort and attention even for a simple task like buttoning a shirt. Natural movements like walking and turning have to be planned as the person will struggle to start and stop actions. Over time, the person will…

India’s relationship with fragrance is ancient, intimate, and profoundly sophisticated. Long before perfume became a global industry, long before it was bottled, branded, advertised, and sold in department stores, fragrance in India was understood as a lived technology-deeply embedded in medicine, ritual, daily grooming, aesthetics, seasonal rhythms, and even spiritual practice. Scent was never merely…

They also found that by studying the exRNA, they could figure out what the bacteria were doing…
Jungle cats (Felis chaus) are found across diverse habitats, from grasslands and wetlands to deserts. They’re present across Asia, with large populations in India and Nepal, among others. The IUCN Red List lists the species as being of ‘least concern’. This has led to a “misconception that they are doing fine”, Kathan Bandyopadhyay, a postdoctoral…
