Engineers have invented an ingenious liquid-metal pump which could make future soft robotics and wearable devices much more portable and agile.

Even the most modern random number generators do not produce perfectly random numbers, which can be a problem for cryptographic applications. 

ETH Zurich researchers use entangled superconducting qubits and a so-called Bell-test to amplify such imperfect randomness using quantum physics. 

Their technology could become a key foundation for secure encryption and digital security. 

The study, published in Communications Medicine, combines magnetic resonance imaging and simulation-based artificial intelligence to speed up brain analysis while maintaining a high level of accuracy.

The method avoids the use of real patient data for training, reduces bias, and could facilitate the implementation of these advanced techniques in hospitals, helping to shorten waiting lists and improve diagnosis.

Based on a 20-year field nitrogen addition experiment, this study demonstrates that long-term high nitrogen deposition does not reduce belowground carbon allocation in tropical forest plants; rather, it induces a physiological adaptation—upregulation of root exudation—to actively mobilize soil phosphorus, thereby sustaining productivity and offering a key mechanistic explanation for the persistence of tropical forest carbon sinks under chronic nitrogen enrichment.

Engineers at Binghamton University, State University of New York have developed a system that creates “digital twins” of real farms, allowing users to walk through fully interactive virtual spaces and observe actual plants in real time – technology that could make farming more accessible for older adults and people with disabilities.
