In everyday life, measuring temperature is pretty straightforward. But in the quantum world, which deals with the super small and the ultra-cold, determining how hot or cold something is starts to get more challenging. Now researchers have described a quantum process that uses a single atom as a thermometer to […]
Invaders, pirates, warriors – the history books taught us that Vikings were brutal predators who travelled by sea from Scandinavia to pillage and raid their way across Europe and beyond. Now cutting-edge DNA sequencing of more than 400 Viking skeletons from archaeological sites scattered across Europe and Greenland will rewrite […]
The eyes of the fruit fly are covered by a thin and transparent coating with anti-reflective, anti-adhesive properties. Researchers discovered that the coating only consists of two ingredients: retinin and corneal wax. They succeeded in artificially reproducing the phenomenon on different kinds of surface. This process, which is very inexpensive […]
Bioengineers have created miniature intestines in a dish that match up anatomically and functionally to the real thing better than any other lab-grown tissue models. The biological complexity and longevity of the new organoid technology is an important step towards enabling drug testing, personalized medicine, and perhaps, one day, transplantations.

She has developed techniques to identify stars likely to host exoplanets, based on the composition of stars known to have planets, and proposes that upcoming studies target stellar phosphorus to find […]
Humans, like other animals, have the ability to constantly adapt to new situations. Researchers have utilized a mouse model to reveal which neurons in the brain are in command in guiding adaptive behavior. Their new study contributes to our understanding of decision-making processes in healthy and infirm people.
Using an X-ray laser, a research team has investigated how water heats up under extreme conditions. In the process, the scientists were able to observe water that remained liquid even at temperatures of more than 170 degrees Celsius. The investigation revealed an anomalous dynamic behavior of water, which is of […]
