Three elongated vertebrae, sheathed in a pale fuzz of microbial mat, resting in the dark almost 6,800 meters below the surface of the Indian Ocean. They belonged to a beaked whale that died somewhere overhead and sank. What gathered on its bones afterward, the worms and brittle stars and tiny grazing snails, is now the … Read more
A droplet of treated wastewater falls thirty centimetres and strikes a thin plastic film. The impact lasts a fraction of a second. Fifteen LEDs flash on. This happens, over and over, inside a modest laboratory at Lanzhou Jiaotong University, where researchers have built a generator that runs entirely on the kinetic energy of falling sewage, … Read more
From the roof of a teaching building at South China University of Technology, a beam of white light crossed 1,200 metres of open air and arrived, intact, at a receiver on the other side of the campus. Not a laser line, not a narrow coherent beam of the kind that demands precise alignment and makes … Read more
Every year, roughly 90 tropical cyclones spin up across the world’s oceans, each one dragging carbon dioxide out of the sea and flinging it into the air. That, at least, is what most scientists assumed. The problem was that nobody had managed to measure the whole thing properly. Ships don’t sail into hurricanes. Moored sensors … Read more
A bowl-shaped particle, roughly a quarter of a micrometre across, drifts through the bloodstream. It’s wearing a disguise: a fragment of membrane stripped from a breast cancer cell, studded with the same proteins that cancer cells use to recognise each other. The immune system ignores it. The particle reaches a tumour, docks, and waits. Then … Read more
A single tooth sits under a microscope in a clean room in Beijing. It is 400,000 years old. The researchers working with it are not allowed to drill into it, grind it down, or section it for analysis. They know that if they damage the morphology, they will have destroyed something irreplaceable. So instead, they … Read more
The liver is, in most respects, forgiving. Damage it repeatedly with alcohol, or hepatitis, or bile that can’t drain, and it will scar. It will tighten and stiffen and lose its architecture over years of insult, eventually becoming the cirrhotic, shrunken organ that kills roughly two million people every year. But it does not simply … Read more
Inside a beam of light, there are places where the light simply isn’t. Not dim, not scattered, not absorbed. Absent, a void of zero intensity threading through the beam like a knotted vein of darkness. These are phase singularities: points where the electromagnetic phase becomes undefined, where the wave collapses into nothing. They dart through … Read more
Somewhere in a Japanese port, a shipping container hums. Inside it, a stack of ceramic wafers, each thinner than a credit card, is converting natural gas directly into electricity without combustion, without turbines, without the thermodynamic waste that haunts conventional power plants. The device is a solid oxide fuel cell, and at roughly 55 per … Read more
Boiling water destroys things. That, more or less, is the assumption underlying decades of nanomedicine research, which has largely ignored traditional herbal teas and decoctions as sources of therapeutic nanoparticles. Lipid membranes, the reasoning went, simply don’t survive prolonged exposure to 100 degrees Celsius. They rupture. They disintegrate. And so researchers seeking plant-derived nanoparticles have … Read more
