An interdisciplinary team of researchers from Nanyang Technological University, Singapore (NTU Singapore), and Delft University of Technology (TU Delft), The Netherlands, has projected that if the rate of global CO2 emissions continues to increase and reaches a high emission scenario, sea levels would as a result very likely rise between 0.5 and 1.9 metres by 2100. The high end of this projection’s range is 90 centimetres higher than the latest United Nations’ global projection of 0.6 to 1.0 metres.
Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team from the University of Innsbruck, together with a team from RWTH Aachen and Forschungszentrum Jülich, has developed a method and implemented it experimentally for the first time, with which a quantum computer can switch back and forth between two correction codes and thus perform all computing operations protected against errors.
A research team led by Associate Professor Ding PAN from the Department of Physics and the Department of Chemistry at the Hong Kong University of Science and Technology (HKUST), in collaboration with Prof. Yuan Yao from the Department of Mathematics, has made significant discoveries regarding the complex reaction mechanisms of carbon dioxide (CO₂) in supercritical water. These findings are crucial for understanding the molecular mechanisms of CO₂ mineralization and sequestration in nature and engineering, as well as the deep carbon cycle within the Earth's interior. This understanding will help pave the way for new directions in future carbon sequestration technologies. The study was published in the Proceedings of the National Academy of Sciences (PNAS)*.
The unprecedented increase in drug overdose deaths in the U.S., long believed to be driven by access to legal and illegal opioids, is most closely tied to an equally dramatic decline in upward income mobility, according to a new analysis by Boston College researchers published in the International Journal of Drug Policy.
While child deaths in England fell temporarily during the COVID-19 pandemic, they have now risen to new heights, a new study from researchers at the University of Bristol and based on unique National Child Mortality Database (NCMD) data has found.
