In the Free State Province, the situation with respect to water and sanitation provision is so dire that it amounts to a human rights crisis. Reinstating water rights and addressing Free State water fragility will require a paradigm shift in the political landscape, not […]
Securing communication in quantum anonymous networks
The demand for secure network communication is increasing as online fraud and cybercrime pose threats to users’ security and data confidentiality. Awais Khan, Dr Junaid ur Rehman and Professor Hyundong Shin, from the Kyung Hee University, Korea, have developed two key protocols for quantum anonymous network communication: the quantum anonymous collision detection (QACD) protocol and quantum anonymous notification (QAN) protocol. […]

RadiaBeam: Safer X-ray sources with smaller particle accelerators
Many important technologies rely on the production of high-energy radiation, yet without the right precautions, the radioactive sources involved in these processes can be incredibly dangerous. Dr Sergey Kutsaev, together with a team at RadiaBeam Technologies, has now shown how these sources could be replaced by compact, low-cost, and flexible particle accelerators, capable of producing high-energy X-rays on demand. His […]

Effective communication in times of risk and crisis: The IDEA model for translating science to the public
From biosecurity and food security to earthquakes and health pandemics, disaster alerts and warning messages can mean the difference between life and death. The COVID-19 crisis for example can at least in part be ascribed to failed risk communication. At the University of Central Florida, Prof Deanna Sellnow and Prof Timothy Sellnow, experts in strategic communication, are tackling this issue. […]
