What is quantum entanglement?
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 showed that even ‘heavy’ particles could follow the same strange quantum physics rules that scientists have mostly observed so...

Earth’s orbits are filling up because governance hasn’t kept pace
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....

Newfound brain network ‘SCAN’ implicated in Parkinson’s disease
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...

Reclaiming India’s fragrance heritage — why a name matters
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...

What is extracellular RNA?
In a study published in the journal Clean Water on March 28, scientists reported that extracellular RNA (exRNA) from bacteria can persist in disinfected drinking water. They also found that by studying the exRNA, they could figure out what the bacteria were doing just before they were damaged or killed, releasing the exRNA. This way,...

Secretive jungle cats need habitats outside protected areas: study
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...

Why does water stay cool in a claypot even in peak summers?
Summers are here, and with them comes an endless thirst. We drink more water than usual and cold water feels almost magical in the heat. Quick fun fact: when you drink cold water, it absorbs heat from your body as it warms up, helping lower your core temperature slightly. At the same time, temperature sensors...
