How plants adapt their root growth to changes of nutrients — ScienceDaily

Like any other plant, Arabidopsis thaliana or mouse-ear cress, needs nitrogen to survive and thrive. But, like maize, beans and sugar beet, it prefers nitrogen in the form of nitrate, growing better on nitrate rich soil. Whereas, pine and rice for example preferentially grow on ammonium nutrition, another form of the key macronutrient nitrogen. If […]

Autophagy helps cells adapt to changing conditions — ScienceDaily

Cells must utilize nutrient resources as efficiently as possible in order to ensure survival. This involves an intricate balance between the synthesis and degradation of cellular components, the latter of which can be used to liberate metabolites from unneeded components during periods of stress. Autophagy is a key intracellular degradation pathway that is triggered under […]

Animals are finding surprising ways to adapt to rising temperatures

A third of the world’s species could go extinct in 50 years due to climate change’s increased temperatures, researchers from the University of Arizona have found. (Alex Strachan from Pixabay/) At this point, the science is clear that sooner than later, we’ll have to say goodbye to a lot of animals and plant species around […]

The future’s uncertain, but noradrenaline can help us adapt — ScienceDaily

A brain chemical called noradrenaline is responsible for our responses to uncertain situations — helping us to learn quickly and adapt our behaviour, a new study has found. The COVID-19 pandemic has plunged us all into a state of uncertainty. In a rapidly changing situation where it is hard to know what will happen next, […]

Urban gulls adapt foraging schedule to human activity patterns

Credit: CC0 Public Domain If you’ve ever seen a seagull snatch a pasty or felt their beady eyes on your sandwich in the park, you’d be right to suspect they know exactly when to strike to increase their chances of getting a human snack. A new study by the University of Bristol is the most […]

Malaria parasites adapt to survive the dry season — ScienceDaily

The main parasite that causes malaria can alter its gene expression to survive undetected in the human blood stream, new research has shown. A team of international researchers, including Dr Mario Recker from the University of Exeter, has studied how the parasite, Plasmodium falciparum, can lie seemingly dormant during unfavourable conditions. The study explains how […]

How bacteria adapt their machinery for optimum growth

The most important components for the functioning of a biological cell are its proteins. As a result, protein production is arguably the most important process for cell growth. The faster the bacterial growth rate, the faster protein synthesis needs to take place. Because protein synthesis is the most expensive cellular process in terms of cellular […]
