- Scientists just recreated a 1938 experiment that could rewrite fusion historyA groundbreaking collaboration between Los Alamos scientists and Duke University has resurrected a nearly forgotten 1938 experiment that may have quietly sparked the age of fusion energy. Arthur Ruhlig, a little-known physicist, first observed signs of deuterium-tritium (DT) fusion nearly a decade before its significance became clear in nuclear science. The modern team not only […]
- This breakthrough turns old tech into pure gold — No mercury, no cyanide, just light and saltAt Flinders University, scientists have cracked a cleaner and greener way to extract gold—not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool disinfectants and a novel polymer that can be reused, the method avoids toxic chemicals like mercury and cyanide. It even works on […]
- Self-lighting chip uses quantum tunneling to spot a trillionth of a gramImagine detecting a single trillionth of a gram of a molecule—like an amino acid—using just electricity and a chip smaller than your fingernail. That’s the power of a new quantum-enabled biosensor developed at EPFL. Ditching bulky lasers, it taps into the strange world of quantum tunneling, where electrons sneak through barriers and release light in […]
- Scientists freeze quantum motion using ultrafast laser trickHarvard and PSI scientists have managed to freeze normally fleeting quantum states in time, creating a pathway to control them using pure electronic tricks and laser precision.
- Researchers develop recyclable, healable electronicsElectronics often get thrown away after use because recycling them requires extensive work for little payoff. Researchers have now found a way to change the game.
- Ultra-thin lenses that make infrared light visiblePhysicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.
