Rethinking distance in massive networks
Indian Institute of Technology GandhinagarA 25-year graph algorithm gap for the All Pairs Shortest Paths (APSP) problem has been narrowed by Dr Manoj Gupta, an Associate Professor at the Department of Computer Science and Engineering, Indian Institute of Technology Gandhinagar. Previous methods provided distance estimates that were no worse than twice the actual distance (2-approximation) and worked effectively only for distant points. The new method, however, offers a reliable 2-approximation guarantee for the APSP problem while handling considerably closer spots with the same efficiency. This advance helps make large-scale network analysis faster and more practical across many real-world systems.
Cuscutae Semen ameliorates mepanipyrim-induced visual impairment in zebrafish via the phototransduction pathway with identification of potential active constituents
Beijing Zhongke Journal Publising Co. Ltd.In the paper published on Science of Traditional Chinese Medicine (STCM), the authors firstly demonstrated that Cuscutae Semen (CS) ameliorated mepanipyrim-induced visual impairment in zebrafish by modulating the phototransduction pathway. It integrated transcriptomics, behavioral assays, and histopathology to reveal CS's restorative effects on retinal structure and function. Notably, chlorogenic acid was identified as a key bioactive constituent. The research provided scientific validation for the traditional use of CS in eye health and offered a novel therapeutic strategy for visual disorders, highlighting the potential of zebrafish models in natural product pharmacology.

Psychology: Study shows limits of multitasking
Martin-Luther-Universität Halle-WittenbergEven with highly extensive training, the human brain is not really capable of performing two tasks simultaneously. Moreover, even the smallest deviations from trained routines can have a significant impact on how quickly and successfully people complete tasks simultaneously. This is shown by a new study conducted by Martin Luther University Halle-Wittenberg (MLU), the FernUniversität in Hagen and the Medical School Hamburg. It was recently published in the “Quarterly Journal of Experimental Psychology”.

Navigating the rainbow: New study defines the "green" standard for global hydrogen energy
Shanghai Jiao Tong University Journal CenterThe environmental impacts of hydrogen production can vary widely depending on the production energy source and process. This implies that the collection and management of sustainability data for hydrogen production globally is desired to ensure accountable development of the sector. Life cycle assessment (LCA) is an internationally recognized tool for environmental impact assessment. Integrating LCA in the holistic evaluation of the hydrogen value chain is desirable to ensure the cleanness and sustainability of the various available hydrogen production pathways. The objective of this review is to evaluate the methodology used in assessing the life cycle impact of hydrogen production including proposed documentation such as the guarantee of origin (GO) and certification schemes, and review case studies from Australia. An analysis of the sustainability strategies and schemes designed by the Australian government, aimed at mitigating climate change and promoting the hydrogen economy, was conducted. The case studies that were discussed identified the preferred available scaled routes of clean hydrogen production to be water electrolysis, which is based on technologies using renewable energy. Other dominant technologies which incorporate carbon capture and storage (CCS) were envisaged to continue playing a role in the transition to a low carbon economy. Additionally, it is critical to assess the greenhouse gas (GHG) emissions using appropriate system boundaries, in order to classify clean hydrogen production pathways. Harmonizing regulatory stringency with appropriate tracking of renewable electricity can promote clean hydrogen production through certification and GO schemes. This approach is deemed critical for the sustainable development of the hydrogen economy at the international level.
