Photochemical renoxification on commercial indoor photoactive paint
Abstract Surface chemistry plays an important role in the indoor environment owing to the large indoor surface to volume ratio. This study explores the photoreactivity of surfaces painted with a photoactive paint in the presence of NOx. Two types of experiments are performed; illumination of painted surfaces with a nitrate deposit and illumination of painted…

Efficient prediction of relative ligand binding affinity in drug discovery
A pairwise binding comparison network (PBCNet) has been established for predicting the relative binding affinity among congeneric ligands, using a physics-informed graph attention mechanism with a pair of protein pocket-ligand complexes as input. PBCNet shows practical value in guiding structure-based drug lead optimization with speed, precision, and ease-of-use. This is a preview of subscription content,…

A comparison of neuroelectrophysiology databases
Abstract As data sharing has become more prevalent, three pillars – archives, standards, and analysis tools – have emerged as critical components in facilitating effective data sharing and collaboration. This paper compares four freely available intracranial neuroelectrophysiology data repositories: Data Archive for the BRAIN Initiative (DABI), Distributed Archives for Neurophysiology Data Integration (DANDI), OpenNeuro, and…

The effect of neuter status on longevity in the Rottweiler dog
Abstract Surgical sterilization or neutering of dogs is a commonly performed procedure in veterinary practices in many countries. In recent decades, concerns have been raised regarding possible side effects of neutering, including increased risk of certain neoplastic, musculoskeletal and endocrinological conditions. Considering that age serves as a significant confounding factor for some of these conditions,…

Plastics are just the tip of the iceberg
The rapid increase in plastics waste is worrying, but approaching sufficiency in a broader sense can tackle much more than plastic waste streams only, argues Sylvia Lorek. And still, plastics accumulating in the environment are mainly a littering problem. Total figures about plastics need to be assessed in relation to the flows of other materials.…

Lighting-environment-adjustable block-type 3D indoor PV for wireless sensor communication
Abstract Demand is increasing for photovoltaics (PVs) as a result of the development of the Internet of Things and edge computing technologies. As the lighting environment is different for the applications, thus, PVs must be adjustable to various light environments in which systems are installed. PVs should therefore be capable of easily changing their morphology…

Turning the tide against antimicrobial resistance in Africa
Jimmy Nkaiwuatei is the Head of Research, Discovery and Innovations at Students Against Superbugs Africa, a youth-led organization tackling the problem of antimicrobial resistance through education and outreach in Africa. One day in 2019, I accidentally came across a schoolmate at the university, and while we were chatting together, I learnt about his great interest…

CCUS development in China and forecast its contribution to emission reduction
Abstract Nowadays environmental issues have been of great concern to the world, among which the problem of global warming caused by greenhouse gas emissions is particularly prominent. All countries in the Kyoto Protocol and the Paris Agreement have committed to control greenhouse gas emissions, and China, as the largest carbon emitter, has assumed a heavier…

Living guidelines for generative AI — why scientists must oversee its use
Nearly one year after the technology firm OpenAI released the chatbot ChatGPT, companies are in an arms race to develop ‘generative’ artificial-intelligence (AI) systems that are ever more powerful. Each version adds capabilities that increasingly encroach on human skills. By producing text, images, videos and even computer programs in response to human prompts, generative AI…
