Physicists at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) have investigated to which extent a piece of music can evoke expectations about its progression. They were able to determine differences in how far compositions of different composers can be anticipated. In total, the scientists quantitatively analyzed more than 550 pieces from classical and jazz music.

Nuclear fusion could be an ideal solution to mankind’s energy problem, guaranteeing a virtually limitless source of power without greenhouse gas emissions. But there are still huge technological challenges to overcome before getting there, and some of them have to do with materials.

Science can be difficult to explain to the public. In fact, any subfield of science can be difficult to explain to another scientist who studies in a different area. Explaining a theoretical science concept to high school students requires a new way of thinking altogether.

In a paper published in Chaos, researchers from Sergio Arboleda University in Bogotá, Colombia, and the Georgia Institute of Technology in Atlanta used an electrophysiological computer model of the heart’s electrical circuits to examine the effect of the applied voltage field in multiple fibrillation-defibrillation scenarios. They discovered far less energy is needed than is currently used in state-of-the-art defibrillation techniques.

New materials designed by a University of Illinois Chicago graduate student may help scientists meet one of today’s biggest challenges: building superconductors that operate at normal temperatures and pressures.

A new hydrogel semiconductor from the University of Chicago offers a groundbreaking solution for bioelectronics, blending tissue-like properties with high electronic functionality, enhancing medical device integration and effectiveness.

The perfect material for interfacing electronics with living tissue is soft, stretchable, and as water-loving as the tissue itself, making hydrogels an ideal choice. In contrast, semiconductors, the key materials for bioelectronics such as pacemakers, biosensors, and drug delivery devices, are rigid, brittle, and hydrophobic, making them impossible to dissolve in the way hydrogels have traditionally been built.

Our ability to see begins with the light-sensitive photoreceptor cells in our eyes. A specific region of the retina, called the fovea, is responsible for sharp vision. Here, color-sensitive cone photoreceptors enable us to detect even the smallest details. The density of these cells varies from person to person.

Additionally, when we fixate on an object, our eyes make subtle, continuous movements, which also differ between individuals.

Researchers from the University Hospital Bonn (UKB) and the University of Bonn have now investigated how sharp vision is linked to these tiny eye movements and the mosaic of cones. Using high-resolution imaging and micro-psychophysics, they demonstrated that eye movements are finely tuned to provide optimal sampling by the cones. The results of the study have now been published in the journal eLife.

A new statistical model could help to address the age-old question of how to price non-physical, intangible goods like data, say scientists.
