Newly discovered gene regulates balance of ‘bad cholesterol’
In a publication in Science, Noam Zelcer from the Division of Biopharmaceutics describes a previously unrecognized pathway to regulate LDL-cholesterol levels. He is also able to modulate this pathway. This opens the possibility for complementing and improving the efficacy of statins: A class of drugs…

Plant stress increases: New research with bacteria offers hope
Soil that is too wet, or too dry. Or with a lot or few nutrients. Due to climate change, the differences are becoming bigger, and plants must increasingly be able to adapt to survive. How do you make plants more stress-resistant? For this purpose, researchers from Leiden, along with other universities,…

Evolutionary change in protective plant odours
Plants can’t run away from enemies. Still, it would like to keep life-threatening herbivores at a distance. This can be done with odours. Klaas Vrieling of the Institute of Biology Leiden found out with his team how plants change odour production to keep the munchers at a distance.

Major international study links genes to brain structural changes over time
There seem to be genes that influence how our brains develop over time. A large international consortium has discovered this with an extensive study. The results of the study were recently published in Nature Neuroscience.

Why are plants not black?
All kinds of reasons have been put forward for why plants apparently fail to make maximum use of the available light. None of these reasons can explain why after two billion years of evolution they are not black, like industrial photovoltaic solar cells. Are we missing something?

ERC grant for Sebastian Pomplun to precisely influence gene expression
In order to stop a whole range of diseases or disorders at their source, you would have to be able to switch certain genes on or off. Sebastian Pomplun wants to develop substances that can do this very precisely. For example, he wants to disrupt cancer processes and make cells produce an important missing…

Fewer flowering plants in Dutch nature: national and international media coverage
In Dutch nature, plant species that depend on pollination by insects are disappearing. Environmental scientist Kaixuan Pan shows this after analysing 87 years of measurements from more than 365,000 locations. Several national and international media reported on the study results. Below is an overview…

Asynchrony among plant communities stabilises ecosystem
Fluctuations in individual plant communities contribute to the stability of an ecosystem as a whole, a study published in Ecology Letters shows. Nadia Soudzilovskaia and colleagues for the first time used data from plant communities across five continents to prove this hypothesis.

Why plants in wetlands are highly productive
Environmental scientists in Leiden have found that the so-called leaf economics spectrum for plants can not only be applied to terrestrial ecosystems, such as forests and grasslands, but also to wetlands. Furthermore, they showed that wetland plants generally have a fast-return strategy, meaning they…

New light on innate plant immunity
Plants are able to resist a pathogen’s attack by a dual innate immune system. The relationship between the two pathways was not clear, but it turns out that they mutually potentiate each other, as assistant professor Pingtao Ding (Institute of Biology Leiden) and colleagues (The Sainsbury Laboratory,…
