Zhenda Xie at Nanjing University has created cheap quantum encrypted communication between drones. Above – Quantum network and physical realization with mobile drone-based nodes. (a) A practical quantum network consists of multinode structure and should provide access for users at any time. (b) If link distance is over the Rayleigh length limit, the beam aperture will be divergent and become …

The far-reaching effects of wildfires and wildfire smoke are no longer aberrations, researchers write in a new paper. Record-setting wildfires torched huge swaths of western states in 2020. They blotted out the sun, produced hazardous air pollution in cities far from the blazes, and …

Warming ocean waters could reduce the ability of fish, especially large ones, to extract the oxygen they need from their environment, researchers report. For their new study in the Proceedings of the National Academy of Sciences, the researchers developed a new model to determine …

The intestines and their bacteria are sometimes called our “second brain,” but studying these bacteria in their natural environment is difficult. Researchers hope to gain more knowledge of the role played by …
It’s not often that a twitching, snowman-shaped blob of 3D human tissue makes someone’s day. But when Dr. Sergiu Pasca at Stanford University witnessed the tiny movement, he knew his lab had achieved something special. You see, the blob was evolved from three lab-grown chunks of human tissue: a mini-brain, mini-spinal cord, and mini-muscle. Each individual component, churned to eerie …

Researchers have used small robots to show off a new theory about when and how groups of particles, robots, or animals with seemingly messy behavior become orderly. The theory addresses a remaining challenge across science and engineering. In the 19th century, scientists and engineers …
2026-2031 India’s reusable launch vehicle is operational During this period, a two-stage-to-orbit (TSTO) reusable launch vehicle is developed by the Indian Space Research Organisation (ISRO). This follows successful testing of smaller, scaled-down versions, which demonstrated important technologies such as autonomous navigation, guidance and control, hypersonic and scramjet flight, a reusable thermal protection system, and re-entry mission management. An …
The $100 million Breakthrough Listen Initiative, founded by Russian billionaire, technology and science investor Yuri Milner and his wife Julia, has identified a mysterious radio signal that seems to come from the nearest star to the sun, Proxima Centauri. This has generated a flood of excitement in the press and among scientists themselves. The discovery, which was reported by the …
2023-2027 A tipping point for block chain Bitcoin is a form of digital money that was created in 2009 by an unknown person. As a decentralised virtual currency, the system is peer-to-peer and transactions take place between users directly, without the need for banks or transaction fees.* These payments are verified by network nodes and recorded in a …

Researchers are starting to figure out how a plant system—which helps plants manage various types of Earthly stresses, such as extreme heat—might function in space. To grow food beyond planet Earth is tricky. Crop plants face unusual conditions for them, like microgravity, radiation, freezing …
