Fields are covered with dandelions in spring, a very common plant with yellow gold flowers and toothed leaves. When they wither, the flowers turn into fluffy white seed heads that, like tiny parachutes, are scattered around by the wind. Taraxacum officinale, that is its scientific name, inspired legends and poems and has been used for centuries as a natural remedy for many ailments.

Scientists from the Skoltech Center for Design, Manufacturing and Materials (CDMM) and the Institute for Metals Superplasticity Problems (IMSP RAS) have studied the fatigue behavior of additive-manufactured high-entropy alloys (HEA). The research was published in the
Journal of Alloys and Compounds.
Conventional 20th century materials that are extensively used in industries and mechanical engineering have reached their performance limit. Nowadays, alloying is commonly used to improve the alloys mechanical performance and increase their operating temperature. An alternative to alloying, HEAs containing equal atomic fractions of their constituent elements were first obtained in 2004. Since then, various publications have offered ample evidence of excellent mechanical performance of HEAs over a broad temperature range. Most of the characteristics were demonstrated for HEAs manufactured by traditional metallurgy techniques.

Information is encoded in data. This is true for most aspects of modern everyday life, but it is also true in most branches of contemporary physics, and extracting useful and meaningful information from very large data sets is a key mission for many physicists.
In statistical mechanics, large data sets are daily business. A classic example is the partition function, a complex mathematical object that describes physical systems at equilibrium. This mathematical object can be seen as made up by many points, each describing a degree of freedom of a physical system, that is, the minimum number of data that can describe all of its properties.
Systemic fungal infections are much rarer than other illnesses, but they are potentially deadly, with limited options for treatment. In fact, fungi are becoming increasingly resistant to the few drugs that are available, and infections are growing more common. A cover story in
Although the use of pesticides in agriculture is increasing, some farms have transitioned to organic practices and avoid applying them. But it s uncertain whether chemicals applied to land decades ago can continue to influence the soil s health after switching to organic management. Now, researchers reporting in ACS
