The evolution of low-temperature adapted enzymes
2025-03-25
Life has evolved over billions of years, adapting to the changing environment. Similarly, enzymes—proteins that speed up biochemical reactions (catalysis) in cells—have adapted to the habitats of their host organisms. Each enzyme has an optimal temperature range where its functionality is at its peak. For humans, this is around normal body temperature (37 °C). Deviating from this range causes enzyme activity to slow down and eventually stop. However, some organisms, like bacteria, thrive in extreme environments, such as hot springs or freezing polar waters. These extremophiles have enzymes adapted to function in harsh conditions.
For ...

New type of quantum computer studies the dance of elementary particles
2025-03-25
The standard model of particle physics is our best theory of the elementary particles and forces that make up our world: particles and antiparticles, such as electrons and positrons, are described as quantum fields. They interact through other force-fields, such as the electromagnetic force that binds charged particles.
To understand the behaviour of these quantum fields and with that our universe, researchers perform complex computer simulations of quantum field theories. Unfortunately, many of these calculations are too complicated for even our best supercomputers and pose great challenges for quantum computers as well, leaving many pressing ...
