The branch of mathematics known as topology has become a cornerstone of modern physics thanks to the remarkable -- and above all reliable -- properties it can impart to a material or system. Unfortunately, identifying topological systems, or even designing new ones, is generally a tedious process that requires exactly matching the physical system to a mathematical model. Researchers have demonstrated a model-free method for identifying topology, enabling the discovery of new topological materials using a purely experimental approach.

Researchers have presented a new study on cyberattack risks to offshore wind farms in Glasgow, United Kingdom. They looked specifically at wind farms that use voltage-source-converter high-voltage direct-current (VSC-HVDC) connections, which are rapidly becoming the most cost-effective solution to harvest offshore wind energy around the world. They found that their complex, hybrid-communication architecture presents multiple access points for cyberattacks.

Human pathologists are extensively trained to detect when tissue samples from one patient mistakenly end up on another patient's microscope slides (a problem known as tissue contamination). But such contamination can easily confuse artificial intelligence (AI) models, which are often trained in pristine, simulated environments, reports a new study. Each of the four AI models in the study paid too much attention to the tissue contamination, which resulted in errors when diagnosing or detecting vessel damage, gestational age, lesions and prostate cancer, the study found.

Web 3.0 is a blockchain technology-based internet paradigm that is transparent and decentralized. But, Web 3.0 streaming services require modifications to the existing service structure due to certain technical issues. Now, researchers propose 'Retriever,' an Inter-Planetary File System (IPFS) based Web 3.0 technology and non-fungible token marketplace. The proposed marketplace reduces service delay and improves user experience by deploying their own IPFS nodes and controlling the blockchain.

Scientists have created a working nanoscale electomotor. The science team designed a turbine engineered from DNA that is powered by hydrodynamic flow inside a nanopore, a nanometer-sized hole in a membrane of solid-state silicon nitride. The tiny motor could help spark research into future applications such as building molecular factories or even medical probes of molecules inside the bloodstream.
