Atomic clocks are the most precise timekeepers in the world. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a constant frequency, like many microscopic pendulums swinging in sync. The best atomic clocks in the world keep time with such precision that, if they had been running since the beginning of the universe, they would only be off by about half

Though it sounds like something straight out of science fiction, controlling the speed of light has in fact been a long-standing challenge for physicists. In a study recently published in Communications Physics, researchers from Osaka University generated light bullets with highly controllable velocities. According to Albert Einstein's principle of relativity, the speed of light is constan

Researchers in Japan and Italy are embracing chaos and nonlinear physics to create insectlike gaits for tiny robots - complete with a locomotion controller to provide a brain-machine interface. Biology and physics are permeated by universal phenomena fundamentally grounded in nonlinear physics, and it inspired the researchers' work. In the journal Chaos, from AIP Publishing, the grou

To reduce the time, cost and risk of developing spaceflight-qualified systems, designers may start with Commercial-Off-The-Shelf (COTS) devices that can later be replaced by their space-qualified, radiation-tolerant equivalent parts available in plastic or ceramic packages featuring the same pinout distribution. Microchip Technology Inc. has announced a radiation-tolerant, 64 Megabit (Mbit

The space domain is undergoing an unprecedented era of change and this rapid transformation presents an exciting future with new possibilities for innovation. But these opportunities also create new challenges and emerging adversaries that must be anticipated and addressed. Outpacing the threat will require more collaboration across the national security enterprise and the necessary integrated m

COVID-19 has revolutionised security practices along with other parts of everyday life: screening people via personal ‘patdowns’ is no longer safe. ESA-developed passive terahertz technology – enabling the detection of items hidden under clothing from a distance – is helping to fill the gap. The US Customs and Border Protection agency is among the latest of more than 200 users of the technology, deploying it to secure the US border.
