Zebrafish let you see the biological fate of nanoparticles in vivo

Ever wondered if you could see through the body of a living organism and observe the dynamic interplay between cells and nanoparticles injected into the bloodstream? This is now possible as the use of transgenic zebrafish embryos now offers a unique opportunity for intravital microscopy at imaging resolutions unrivalled by existing mammalian…

It is spring, the trees are turning green, and suddenly winter returns. Admittedly, just for a short visit, but many plant species cannot withstand this sudden change. Photo: Colourbox.
By integrating data on the climate and the properties of plants, the researchers created this map, which shows how the risk of frost damage to trees changes over time. The red areas are of particular concern. The frequency of late spring frosts increases drastically over time in these areas, and the trees have leaves with low resistance to frost.

Global warming means more frost damage to trees in Europe and Asia

A global research project has demonstrated that climate change entails a higher risk of freezing temperatures late in the spring. This can damage forests in Europe and Asia, where plants are not accustomed to this kind of fluctuation in the temperature and therefore start to blossom and grow leaves as soon as it is warm enough. In North America,…

One third of the world's population are in risk of being exposed to temperatures like the hottest parts of the Sahara desert within 50 years, if the human greenhouse gas emmissions continue unabated. Photo: Colourbox.
Expansion of extremely hot regions in a business-as-usual climate scenario. In the current climate, mean annual temperatures >290C are restricted to the small dark areas in the Sahara region. In 2070 such conditions are projected to occur throughout the shaded area following the RCP 8.5 scenario. Without migration, that area would be home to 3.5 billion people in 2070 following the SSP3 scenario of demographic development. Background colours represent the current mean annual temperatures.

‘Near-unlivable’ heat for one-third of humans within 50 years if greenhouse gas emissions are not cut

Areas of the planet home to one-third of humans will become as hot as the hottest parts of the Sahara within 50 years, unless greenhouse gas emissions fall, according to research by an international team of scientists with participation from Aarhus University published in the journal Proceedings of the National Academy of Sciences this week. The…
