Packages of DNA strands containing silver, measuring just two or three nanometres in size. Leiden physicists Donny de Bruin and Dirk Bouwmeester create these packages, which can enter living cells on their own. They then activate the silver with light, causing the cells to break down. This could, in…

Patients with skin diseases such as eczema and psoriasis, sometimes spend a lifetime searching for the right medication. To help these patients faster and better, scientists across the country are joining forces. The Next Generation ImmunoDermatology (NGID) project, with LACDR professor Robert Rissmann…

A tenacious postdoc researcher persuaded Professor Marc Koper to research the oxygen reduction reaction. In Koper's eyes, there was little of interest there. But they promptly discovered a whole new way to improve fuel cells on hydrogen and oxygen. Their article appeared in Nature Catalysis on 07 Ju…

Dr Irene Groot (LIC) has been appointed professor of Surface and Interface Science with effect from 1 March. The appointment is an honour for Groot. 'It feels like recognition of your research, teaching and leadership qualities.'

A star does not just appear in the sky overnight. Its creation takes tens of thousands of years. Twenty years ago, astronomers took a picture of a star in its birth phase. The James Webb Space Telescope (JWST) could now capture that same star in much greater detail. This does not only provide beautiful…

The Phase 3 clinical trial results of the promising Covid-19 vaccine of Johnson & Johnson are expected this month. The Dutch electron microscopy facility NeCEN helped develop the company’s vaccine, and they have now published their scientific findings in Nature Communications.

Physicist Milan Allan will build an instrument that will bring superconductivity research further. He has been awarded an ERC Consolidator Grant of 2 million euros over the next five years. With his PairNoise programme he aims to detect paired electrons as they occur just above the temperature at which…

Planets existing in other solar systems contain invaluable information about the origin of planets and life. PhD candidate Yapeng Zhang has studied their atmospheres by looking at their smallest parts: isotopes. With her research she hopes to discover what makes our own solar system unique.

Cryogenic memories, antibiotic treatment for urinary tract infections and recycling plastic sustainably. These are the subjects of the three NWO-XS grants awarded to Leiden Science researchers.

This Thursday, January 18th 2024, our esteemed colleague Jan Zaanen passed away. Jan was one of our star scientists, larger than life, with an unabashed, boisterous drive for the best of physics at the Institute Lorentz, at the Leiden Institute of Physics and in the full international scientific community.…

Research on quantum computers and Islamic charities: two Leiden researchers have received a Consolidator Grant from the European Research Council.

Using 2D materials, physics student Romme van der Kemp developed a nanochip that is extremely small ánd scalable. This is needed to make all kinds of technologies better, faster and smaller. He has been nominated for the FWN Young Talent Award 2023 for his research.

Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers at Leiden Observatory in the Netherlands have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor…

Besides physics, the sleep of PhD students also benefits from Vitaly Fedoseev's PhD research. He will receive his doctorate on July 7 for his work on optomechanics within quantum mechanics. And also on a setup that eliminated the need for PhD students to push a button every hour for 72 hours.

Stack two layers of graphene, twisted at slightly different angles to each other, and the material spontaneously becomes a superconductor. Science still can't explain how something so magical can happen, but physicists use special equipment to reveal what is taking place under the surface.

Before researchers can develop targeted drugs, they need to know exactly how a disease works. Biochemist Bert Beerkens created molecules that allow them to find out. He used caffeine as the basis for new molecules that enable research into certain receptor proteins on cells.

Two Leiden Science researchers received an NWO-XS grant for their research. Both projects are highly promising, but also high-risk. Macrophages that trap bacteria and data storage made from 2D materials convinced the board of their potential.

James Webb life’s building blocks

Roll-up solar panels, bendable phone displays, or better computer chips… The EU project STIBNITE investigated the next generation of semiconductors, made from organic materials based on carbon, nitrogen, and boron. The project has now concluded. During the Open Science Debate on 1 July, the group will…

An international team of astronomers led by Ardjan Sturm of the Observatory has made the first two-dimensional inventory of ice in a planet-forming disk of dust and gas surrounding a young star. The researches, including Melissa McClure, used the James Webb Space Telescope and publish their findings…

Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

The Faculty of Science launched the new Academic Year on 21 September with a special We Are Science talk show. Dean Paul Wouters starred in his role as talk show host and received a wide variety of guests.

Jasper Knoester is the dean of the Faculty of Science. How is he doing, what exactly does he do and what does his day look like? In each newsletter, Jasper gives an insight into his life.

The James Webb Space Telescope continues to surprise us with stunning pictures, but of what exactly? Astronomer Nienke van der Marel shows with three images how massive stars lead short but explosive lives.

In brain diseases such as Parkinson's and Alzheimer's, proteins clump together to form fibres. ‘Chaperone proteins’ unravel those fibres, but in the test tube biochemist Anne Wentink saw that this can also cause new problems. She is going to find out what happens inside cells to determine what a drug…

Nathaniel Martin, Professor of Biological chemistry, wondered what would happen if you take an antibiotic that has been known for 70 years and try to improve it with the latest tools of modern chemistry. Turns out it can become up to a hundred times more potent and prevent the growth of some drug-resistant…
