IEEE study demonstrate broadband optical signal filtering with chirped and tilted fiber Bragg grating
Institute of Electrical and Electronics EngineersWhile fiber Bragg grating is widely used for selectively filtering wavelengths during optical transmission, existing techniques are unsuitable for bandwidth filtering of broadband optical signals. Researchers have now demonstrated that chirped and tilted fiber Bragg grating (CTFBG) using femtosecond laser line-by-line technology can facilitate highly specific and versatile bandwidth filtering in broadband signals. The technique may offer several added advantages in optical signal filtering beyond flexibility and customizability.

Navigating the knowledge paradox: Why having some answers can be worse than having none
Yonsei UniversityTemporally complex problem-solving environments are commonplace in organizations. In an innovative study, a researcher from Yonsei University, in collaboration with other scientists, has shown that limited external knowledge in such situations can lead to worse performance than having no external knowledge at all. These findings are expected to further organizational decision-making and strategy, education and training, public policy and healthcare, technology and AI integration, and individual career development.

The climate policies that EU citizens like (and those they don't)
CMCC Foundation - Euro-Mediterranean Center on Climate ChangeAs Europe has been struggling with several heatwaves this summer, a new survey from Summer 2024 reveals how much its citizens are willing to support different kinds of climate policies (n=19,328, 24 June–27 August 2024). As expected, Europeans strongly prefer policies which allocate subsidies for rail transport or home insulation for instance, while they strongly oppose the ones which foresee any kind of tax on polluting behaviours, such as the one on cars and meat.
This new survey highlights interesting trends in Europeans citizens’ preferences and opinions about different possible climate policies currently under discussion. These results are now browsable in an online tool which allows the user to analyse and compare opinions about a set of different climate policies in Europe.
Hatred, the new engine of voting: A landmark study from the University of Lausanne published in Public Opinion Quarterly
University of LausanneA study by Professor Diego Garzia at the University of Lausanne, published in Public Opinion Quarterly, finds that voters in many Western democracies are now driven more by hostility toward opponents than by support for their own party. Analyzing 143 elections across 12 countries from 1961–2022 using “feeling thermometers,” the research shows that out-party hate is growing faster than in-party love, marking a shift toward negative, rejection-driven politics. This trend fuels polarization, hardens public discourse, and threatens democratic compromise.
