Gravitational waves could prove the existence of the quark-gluon plasma

Neutron stars are among the densest objects in the Uiverse. If our Sun, with its radius of 700,000 kilometres were a neutron star, its mass would be condensed into an almost perfect sphere with a radius of around 12 kilometres. When two neutron stars collide and merge into a hyper-massive neutron star, the matter in the core of the new object becomes incredibly hot and dense. According to physical calculations, these conditions could result in hadrons such as neutrons and protons, which are the particles normally found in our daily experience, dissolving into their components of quarks and gluons and thus producing a quark-gluon plasma.

Climate-smart agricultural practices increase maize yield in Malawi

Climate change creates extreme weather patterns that are especially challenging for people in developing countries and can severely impact agricultural yield and food security. International aid organizations have invested billions of dollars in promoting climate-smart agriculture (CSA) practices, but the effects of those programs are rarely documented.

Imaging nematic transitions in iron pnictide superconductors

Researchers at Stanford University have recently carried out an in-depth study of nematic transitions in iron pnictide superconductors. Their paper, published in Nature Physics, presents new imaging data of these transitions collected using a microscope they invented, dubbed the scanning quantum cryogenic atom microscope (SQCRAMscope).

Study shows our sun is less active than similar stars

By cosmic standards the sun is extraordinarily monotonous. This is the result of a study presented by researchers from the Max Planck Institute for Solar System Research in the upcoming issue of Science. For the first time, the scientists compared the sun with hundreds of other stars with similar rotation periods. Most displayed much stronger variations. This raises the question whether the sun has been going through an unusually quiet phase for several millennia.
