DUBAI: Saudi Arabia is making rapid strides in boosting its higher-education standards, with Riyadh’s Princess Nourah bint Abdulrahman University (PNU), one of the Kingdom’s most reputable institutions, recently leaping several spots up the world rankings.
The improvement by 59 points over its previous Universitas Indonesia (UI) GreenMetric World University Ranking makes the PNU the second best in the Kingdom, fourth in the Middle East and 79th globally for its commitment to environmental sustainability.
The annual ranking assesses 912 universities in 94 countries on their sustainability and eco-friendly practices, relying on six main indicators: infrastructure, energy, waste, water, transportation and the level of education.
A polymer designed specifically to generate light that can penetrate turbid environments has exhibited the potential for bioimaging trials, where it can identify nano-sized particles present below the surface of realistic tissue models.

New study indicates that reflecting solar energy back to space in an attempt to reduce global warming could cause more problems than it solves.
Increasing emissions of greenhouse gases into the atmosphere, resulting in an accelerating rise in atmospheric temperature, are creating a hugely significant challenge to people and the planet.
Scientists are looking into the plausibility of ideas that aim to limit the effects of climate change, while carbon emissions from humans burning fossil fuels continue to over-insulate the planet. Solar geoengineering proposes to reflect incoming sunlight back into space by deliberately releasing reflective particles into the upper atmosphere where they block the sun s warming rays.
A polymer that is custom designed to produce light that penetrates murky environments has shown promise in bioimaging trials, where it can detect nano-sized particles underneath the surface of realistic tissue models.
