Why is the leaky faucet – that most irksome domestic malaise – so universal? A new scientific breakthrough seems to have cracked the physics of this incessant drip-drip. A new paper published in Physical Review Lettershas explained how a water jet breaks up into unstoppable droplets. Researchers from the University of Amsterdam found that the...

Low-pH cements could let microbes seal cracks in deep nuclear vaults
Nuclear activities worldwide generate around 200,000 m3 of radioactive waste every year. Of this about 10,000 m3, less than 5% by volume but containing most of the radioactivity, needs deep, long-term geological storage in the form of geological disposal facilities (GDFs). These caverns purpose-built hundreds of metres underground are packed with waste containers, cement backfill,...

World Soil Day: Grassland soils, not trees, anchor India’s climate resilience
“Wastelands”. That’s how India’s biodiverse semi-arid grasslands and savannas have been undervalued ever since the British colonial era. For the masters, the woody forests of the subcontinent fuelled industrialisation, while the grassy biomes served no purpose in their timber-driven colonisation. Much of post-independence policy and jurisprudence drew heavily from the erstwhile rulers and “wastelands” made...

Malaria parasites corkscrew their way deeper through skin
Helical paths are everywhere in the microscopic realm. Many bacteria and parasites don’t simply swim or glide in straight lines. In three dimensions, they trace corkscrew-like tracks through their surroundings. Malaria parasites, for example, glide through soft 3D gels and, in the skin of a bitten host, on paths that look like stretched springs. For...

One-atom experiment settles Einstein’s challenge in Bohr’s favour
In the 1920s, Albert Einstein proposed a twist on the double-slit experiment. Rather than a wall with two fixed slits, he imagined a very light slit that would recoil when a single photon passed through it. If one could measure that recoil, one could in principle tell which path the photon took. At the same...

No, no, noise: The noise cancellation science
Our reality is a yes, yippie one for noise. We are always swimming in it. Sound waves pervade our atmosphere and a certain portion of those sound waves are what we refer to as noise (Sounds change into its alter ego ‘noise’ when we, subjectively, don’t want them there or think they are too disruptively...

Why do we feel the need to go to the bathroom when we’re nervous or scared?
When you’re nervous or scared, your body enters its fight-or-flight mode, controlled by the autonomic nervous system. Adrenaline levels rise, your heart races, palms sweat, and blood flow and muscle tone are redistributed to prepare you to act. Your bladder and bowels are controlled by smooth muscle and sphincters. Stress hormones can make the bladder...
