Data science is of vital importance in preventing future outbreaks of viruses, Professor of Data Science Aske Plaat argues. Inaugural lecture entitled ‘Data Science and Ebola’ on 13 April.

Today, everybody and everything produces data. People produce large amounts of data in social networks and in commercial transactions. Medical, corporate, and government databases continue to grow. Sensors continue to get cheaper and are increasingly connected, creating an Internet of Things, and generating…

In STAYAHEAD data-intensive approaches are being developed to ”decode the human immunome” with a focus on a global vaccine strategy. They have developed a rapid mass spectrometric test to analyse in real-time large numbers of variants of SARS-CoV-2 and the host immune response, and use these data to…

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

Following current regulations regarding the attempts to constrain the effects of the Corona virus outbreak, the University of Leiden has cancelled all physical forms of teaching until 6 April. As conference organisers, we will use this period to consider how to proceed with the conference. In the most…

VODAN Africa started as a platform to enable access to critical data needed from Africa to fight the novel COVID-19. The initiative was inspired by the experience from the Liberia Ebola Virus outbreak in 2014: early detection requires contact tracing. Inclusion of the most vulnerable is critical to…

This was accomplished by a combination of experimental research in the group of Ton Schumacher (Dutch Cancer Institute, NKI) and computer simulations in collaboration with Rob…

Due to the by now world-wide Covid19 restrictions on travelling and holding meetings, the committee has decided to cancel the conference in June. We are now looking into postponing the conference (either to a later date in 2020 or to 2021). We will keep you informed about any further developments. All…

Assistant Professor Christopher Green was interviewed on ABC Australia about the recent COVID-19 outbreak in North Korea. Green says that the statistics the isolated country has given are ‘essentially nonsense’.

What Accounts for the Variety of National Policy Responses to the COVID-19 Pandemic in Europe?

Moritz Jesse, Associate Professor at the Europa Institute Leiden, was a speaker at the International Conference European Constitutionalism And the Virus of Distrust Conference, which took place on 27 and 28 April in Prague. The Conference brought together academics from all over the European Union to…

Gathering and distributing patient data can make an important contribution to containing the coronavirus. But if we want to be successful, we need better data. With this objective in mind, Leiden data stewards have joined the Virus Outbreak Data Network (VODAN).

Professor of Ecotoxicology Martina Vijver had planned an eight-week field work course for her students, but the corona virus threw a spanner in the works and Vijver had to come up with a new plan at short notice. ‘Without the help of my own network and that of my colleagues this would have been very…

Epithelial cells play a crucial role in the lungs. PhD student Ying Wang researched the effects of cigarette smoke and viruses such as COVID-19 on these epithelial cells. ‘We hope to reduce the risk of pandemics in the future.’

Knowing how to resolve global problems is one thing, but how do you make sure that it actually happens? That’s the real challenge, because there are powerful movements everywhere that want to reconstruct the walls of nation states. In an attempt to resolve this issue, Leiden researchers are experimenting…

An overview of awards and prizes granted to our staff and students in 2019, as well as special appointments and royal distinctions.

Seasonal influenza vaccines provide protection against matching influenza A virus (IAV) strains mainly through the induction of neutralizing serum IgG antibodies. However, these antibodies fail to confer a protective effect against mismatched IAV. This lack of efficacy against heterologous influenza…

The Open Day of Leiden University, on the 8th of this month, was a success again: 483 prospective students came to find out what Leiden has to offer. The Institute of Biology Leiden was also present.

The people behind the Leiden University Libraries aim to maintain the level of their services to clients as much as possible. They are making thankful use of internet, but not everything can be put online.

The potential of bioneedles to deliver influenza vaccines was investigated.

It’s all hands on deck at the moment to resolve the COVID-19 crisis. Researchers from various disciplines are helping where they can, also from the field of artificial intelligence (AI). AI offers great opportunities both at the frontline of the crisis and in its expected aftermath. Leiden professor…

Why have some European countries responded faster to the coronavirus outbreak than others? While in some countries the lockdown had already been declared when relatively few cases were known, others did not take action until thousands of people were already infected and hundreds were already dead. What…

The aim of the REACT Study is to examine whether baseline inflammation, and/or neuro-immune responses to stress in a sample of adolescents with experiences of childhood adversity predicts: the perception of stress, social behaviour and general mental and physical health during and after the COVID-19…

In a joint letter, the Leiden student associations have appeal to students to practise 1.5m distancing and to only meet others if they are fit and well. They urge them to observe the corona rules to prevent a local spike.

Fourteen bachelor’s and master’s students are representing Leiden University in this year’s International Genetically Engineered Machine competition (iGEM). Their plan: to create a kit that can be used to quickly identify infectious diseases in case of an outbreak.

New and reemerging infectious diseases call for innovative and efficient control strategies of which fast vaccine design and development represent an important element.

Scientists at the LUMC are working hard on potential virus inhibitors, antiviral screening and a treatment for COVID-19. SteunLeiden.nl has started a crowdfunding campaign for this research, under the hashtag #wakeuptocorona. Professor of Virology Eric Snijder explains why this is desperately needed…

What are 'defects' and mechanical properties of mosaics of different shapes of tiles?

The Viral Vector Facility produces batches of lentivirus and adenovirus for preclinical research within the LUMC. And it assists researchers to produce their own virus.
