While traditional diamonds are formed over billions of years deep in the Earth where extreme pressures and temperatures provide just the right conditions to crystalize carbon, scientists are working on more expedient ways of forging the precious stones. An international team of researchers has succeeded in whittling this process down to mere minutes, demonstrating a Read more about Scientists Produce Rare Diamonds In Minutes At Room Temperature[…]

Airglow is the natural “glowing” of the Earth’s atmosphere. It happens all the time and across the whole globe. There are three types of airglow: dayglow, twilightglow and nightglow. Each is the result of sunlight interacting with the molecules in our atmosphere, but they have their own special way of forming. Dayglow forms when sunlight Read more about Aurora vs Airglow vs STEM[…]

Many hopes for a return to a semi-normal life after COVID-19 revolve around vaccines, but those injections have limits — they’re harder to deploy in low-income and rural areas where there’s no guarantee of easy distribution. Science may offer a more accessible alternative, though. Columbia University researchers have developed a nasal spray that has successfully Read more about Nasal spray might prevent COVID-19 infections – it does in ferrets[…]

Scientists have found evidence that frozen methane deposits in the Arctic Ocean – known as the “sleeping giants of the carbon cycle” – have started to be released over a large area of the continental slope off the East Siberian coast, the Guardian can reveal. High levels of the potent greenhouse gas have been detected Read more about ‘Sleeping giant’ Arctic methane deposits starting to release, scientists find[…]

MIT researchers have now found that people who are asymptomatic may differ from healthy individuals in the way that they cough. These differences are not decipherable to the human ear. But it turns out that they can be picked up by artificial intelligence.

Nearly 60 years ago, the Nobel prize–winning physicist Eugene Wigner captured one of the many oddities of quantum mechanics in a thought experiment. He imagined a friend of his, sealed in a lab, measuring a particle such as an atom while Wigner stood outside. Quantum mechanics famously allows particles to occupy many locations at once—a Read more about Quantum paradox points to shaky foundations of reality[…]

In 1969, British physicist Roger Penrose suggested that energy could be generated by lowering an object into the black hole’s ergosphere—the outer layer of the black hole’s event horizon, where an object would have to move faster than the speed of light in order to remain still. Penrose predicted that the object would acquire a Read more about Experiment confirms 50-year-old theory describing how black holes could generate energy[…]
