Waste Separation
What is better for waste recycling: a plastic, paper or ceramic cup? A bio-based or fossil-based coating? Waste sorting at the source or at a recycling facility? Ask ten experts and you will get ten different opinions. We can all agree on one thing: doing nothing is not an option. Thus, Leiden University…

Urban
Urbanization brings benefits like housing and jobs but also challenges like biodiversity loss. CML's Urban research program uses science to create sustainable cities, focusing on the built environment (circular economy, urban mining) and enhancing urban nature for biodiversity and human benefits.

Invaluable bees and nature’s other services
We depend on nature for so many things: from clean water, wood and food to carbon absorption, water purification and coastal protection, as well as for relaxation, inspiration and identity. Nevertheless, our modern world putting increasing pressure on these ecosystem services. Leiden researchers investigate…

Dutch contribution to the development of African countries in the global value chain
Economies worldwide are increasingly interconnected; trade in raw materials and semi-finished products is increasing. Many products we use in the Netherlands originate abroad, and many products we make in the Netherlands are destined for other countries. Almost all countries around us participate in…

Materials made of self-spinning particles
Materials are either gas, liquid or solid, based on how their molecules respond to temperature and pressure. But what if the building blocks are self-spinning particles instead of ordinary molecules? Theoretical physicists found out what determines the phase of those artificial materials. Publication…

Leiden researchers depict the formation of galaxies
An international team of astronomers, with researchers at Leiden Observatory playing a leading role, has mapped the fuel for galaxy formation in the iconic Hubble Ultra Deep Field. The results of the research have been accepted for publication in The Astrophysical Journal.

Talk and debate: how do we prevent science from harming the environment?
Sustainability researchers can play an important role in the energy transition. But what if their partners are not (yet) sustainable and science itself has adverse effects? This is the subject of an online talk by researcher Thomas Franssen on 16 December with a discussion afterwards. ‘Clean energy…

Got an old mobile left over? Play the Funky Phone Challenge!
Have you got an old mobile phone lying around? If so, you can hand it in at Funky Phone in Lipsius. The phone will be recycled and you get to play an old-fashioned arcade game on the Funky Phone games computer built from discarded electronics. Vice-Rector Hester Bijl kicked off the Funky Phone Challenge…

One-way traffic for motion in new material
Scientists have developed a material that breaks one of the fundamental principles governing many physical systems. Ordinary materials transmit external forces equally, no matter where the pressure comes from. The newly developed material breaks this rule and could potentially be of interest in soft-robotics…

Materials from the past contain lessons for today
Studying ancient materials and the way they were made can give us groundbreaking insights into the past. Not only that, the interplay between people and materials is highly relevant for society today, says Ann Brysbaert, Professor of Ancient Technologies, Crafts and Materials, at the Faculty of Archaeology.…

Ultra-thin material absorbs all the light
It appears to be a paradox: ultra-thin material that absorbs all the incident light. Nonetheless, it does exist. Two Leiden researchers report on their research in ‘Applied Physics Letters’. The article is among the Top 20 of the most downloaded articles of this reputable journal in May.

New material challenges 250 year old building principles
Researchers at FOM-institute AMOLF and the Leiden Institute of Physics (LION) have developed a rubber rod with strange bending behaviours. Beyond a certain point, it bends more under decreasing pressure. This behaviour doesn’t fit our expectations and does not conform to secular laws that predict the…

Indigenous Peoples preserved
Indigenous Peoples possess rich worldviews and unique knowledge that form part of our global heritage. Oppressing these peoples and violating their natural environment is leading to the destruction of this knowledge. Leiden researchers aim to counter this through collaborating with Indigenous Peoples…

Newton-telescope finds missing intergalactic material
Astronomers from, among others, SRON and Leiden Observatory have discovered long-sought intergalactic gas with ESA’s space telescope XMM-Newton. This gas is one of the pieces of the puzzle to map the total amount of ‘normal’ matter in the universe. The research will be published in Nature on 21 June…

“Pulp Fraction”: Tackling the orange waste mountain
During orange juice production only around a half of every orange is turned into juice. Lizah van der Aart and Blair Berger, both MSc-students at the IBL, and Ryan Bogaars from Delft University, received an NWO-scholarship to develop a novel method to extract natural products from orange residue.
