Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date, which works by absorbing heat generated by incoming light. Capable of capturing light from the entire electromagnetic spectrum, the ultrathin device requires no external power, operates at room temperature and can be readily integrated into on-chip applications.
Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum computers can solve complex equations at staggeringly fast speeds that vastly outpace regular computers. In real hardware, the operations of quantum computers often deviate from the ideal behavior because of device imperfections and unwanted noise from the environment. To build reliable quantum machines, researchers need a way to accurately determine what a quantum device is actually doing.
Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic method for quantum computers. It makes errors in individual quantum bits visible during logical calculation and evaluates them. The new method was demonstrated on an ion trap quantum processor in Innsbruck. It can be used to identify critical error sources—a key to developing more robust, fault-tolerant quantum processors.
Just a few days in simulated microgravity can subtly change the way women’s blood clots, sparking bigger questions about health monitoring protocols for astronauts who can spend six months or more in orbit, say Simon Fraser University researchers. First reported in 2020, an International Space Station mission detected an unexpected blood clot in a female astronaut’s jugular vein. To date, space-health research has had more male participants, but with the number of female astronauts on the rise, a new SFU–European Space Agency study examined how microgravity affects blood clotting specifically in women.
In a first, a space mission led by NASA and France has tracked Earth’s rivers swelling and shrinking from month to month over the course of a year and found significantly less of a swing than previous model-based estimates. A record drought in the Amazon likely influenced the tally made by the Surface Water and Ocean Topography (SWOT) satellite. The findings also reveal new details about the underwater topography of the world’s river channels.
Astronomers have reported observations of a rare star system consisting of one star orbiting a system of three more tightly bound stars. This quadruple star system is described in a new study, published in Nature Communications, as the most compact quadruple star system observed to date, with all four stars fitting into an area the size of Jupiter’s orbit.
The NA62 Collaboration has dramatically reduced the uncertainty in its measurement of an extremely rare particle decay, in results just presented at the 2026 La Thuile conference.
Deputy Jose Rivera was struck near his body-worn camera, which may have altered the trajectory of one bullet, Volusia Sheriff Mike Chitwood said
The new directive bars masks intended to conceal identity while permitting use for safety, health and weather-related reasons
Craters, craters, and yet more craters: this snapshot from ESA’s Mars Express is packed full of them, each as fascinating as the last.
The food flying aboard Artemis II is designed to support crew health and performance during the mission around the moon. With no resupply, refrigeration, or late-load capability, all meals must be carefully selected to remain safe, shelf-stable, and easy to prepare and consume in NASA’s Orion spacecraft. Food selections are developed in coordination with space food experts and the crew to balance calorie needs, hydration, and nutrient intake while accommodating individual crew preferences.
An international team of scientists, led by a Ph.D. researcher from Northumbria University, has made further discoveries about a spectacular feature of Jupiter’s northern lights, revealing a never-before-seen temperature structure and dramatic density changes within the top of the giant planet’s atmosphere.
Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images. Yet controlling these properties independently remains difficult, especially when light can enter a device from either side.
