Earlier this year, the South African city of Cape Town was told that it would make history by April 16. On that date, dubbed Day Zero, it was expected to become the world’s first major city to run out of water because of an extended drought. More than 1 million […]

New research overturns a long-held assumption that Przewalski’s horses, native to the Eurasian steppes, are the last wild horse species on Earth.
The wetting and adhesion characteristics of solid surfaces critically depend on their fine structures. However, until now, our understanding of exactly how the sliding behavior of liquid droplets depends on surface microstructures has been limited. Now, physicists have conducted experimental and theoretical studies on the friction of liquid droplets on […]
Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to ensure it is working reliably? Depending on the algorithmic task, this could be an easy or a very difficult certification problem. An international team of […]
When a complex system is left alone, it will return to its initial state with almost perfect precision. Gas particles in a container, for example, will return almost exactly to their starting positions after some time. For decades, scientists have investigated how this ‘Poincaré Recurrence Theorem’ can be applied to […]
Pre-clinical animal research is typically based on single laboratory studies conducted under highly standardized conditions. But in a new study, researchers show that this near-universal practice may actually help to explain the poor reproducibility of pre-clinical animal research. Instead of standardized conditions, diversity may be better.
Glowing creatures like fireflies and jellyfish are captivating to look at but also a boon for science, as their bioluminescent molecules contribute to visualizing a host of biological processes. Now, scientists have supercharged these molecules, making them hundreds of times brighter in deep tissues and allowing for imaging of cells […]
Sepsis occurs when the body’s response to the spread of bacteria or toxins to the bloodstream damages tissues and organs. The fight against sepsis could get a helping hand from a surprising source: gut bacteria. Researchers found that giving mice particular microbes increased blood levels of immunoglobulin A (IgA) antibodies, […]
