Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

When the tokay gecko loses its tail, a new one grows from resident stem cells at the stump. Each tissue type - muscle, bone, blood vessels and skin - develops from specific stem cells. This discovery by Luthfi Nurhidayat holds potential implications for advancing regenerative medicine in humans. Nurhidayat…

The first book ever on information-theoretically secure multiparty computation

The battle for a strong power position in the run up to the provincial council elections in the Netherlands is currently being fought fiercely. Prime Minister Mark Rutte has become accustomed to a minority in the Senate in recent years. The four Rutte cabinets were always able to do business with various…

Robert Ietswaart does research into gene regulation at the famous Harvard Medical School in Boston. He developed an algorithm to better predict whether a candidate medicine is going to produce side effects. He studied mathematics and physics in Leiden, and gained his PhD in computational biology in…

Could water be present in planet-forming disks before the formation of rocky planets? The James Webb Space Telescope may have found evidence for that. Webb has for the first time observed water in the inner disc around young star where at greater distance, giant planets have already formed. The research…

Artificial photosynthesis has recognised potential to produce green and sustainable fuels from earth-abundant resources such as water, carbon dioxide (CO2), and sunlight.

The SNP genotyping line offers flexible genotyping for small and large projects at affordable price and high quality. The use as SNPs as molecular markers is very versatile and can be used for a wide variety of scientific questions ranging from paternity analysis, conservatuion genetis towards QTL…

Every year, the Leiden Institute of Physics (LION) organises the Science Day. The goal is to highlight the newest research at LION, to socialise, and to welcome first year master students and new PhD candidates to our institute.

Research at the BPOC/SSNMR group is comprised of the following research themes:

Daily management at the Institute of Biology Leiden is executed by the Scientific Director, the Director of Education, the Director of Operations and the Management Assistant. Research and education are managed collaboratively, with strategic input from various representatives and gremia, including…

The CIGR brings together a diverse range of unique expertise in genome research rooted in biology, chemistry and physics. Members of the CIGR investigate genome folding and genome transactions. An important aspect is direct as well as long term relevance for medicine.

Biosynthetic gene clusters (BGCs) for natural products are widespread in microbial genomes, and they are rapidly exchanged. This research assesses the factors that control the spread of BGCs and resistance genes in nature. This includes risk assessment for the spread of engineered DNA in nature.

From molecule, to cell, to organism. The high-level drug research at the Cell Observatory aimes at reducing the spread of cancer and developing new medicines for tuberculosis.

The Museums, Collections & Society research programme is led by the Faculty of Humanities and the Faculty of Archaeology and aims to promote collection-based research, stimulate Leiden education in this field, and raise ethical questions regarding the collections’ origins.

A liveable planet. More biodiversity. And resources which are being managed wisely. At the CML, we want to make an impact with our research and education. On this website you can read what we do to achieve that.

For a first time the atlas maps the soil biodiversity of the entire planet, and provide s comprehensive analysis of human-induced threats to soil organisms and soil functioning, facilitating development of new policies to protect soil and soil organisms.

Long-distance Trade in Early Medieval Landscapes (ca. 6th-12th centuries)

Rembrandt painted this Flora, the Roman goddess of spring, in 1635. She is on display above the archway leading from the Academy Building to the lush flora of the University’s Hortus Botanicus. Rembrandt, who had his own cabinet of curiosities, almost certainly knew this botanical garden, the oldest…
