The climate transition, energy supply and technological development are just some examples of areas where knowledge from several disciplines needs to come together to find relevant solutions. Engineering students are therefore often given the opportunity to work on interdisciplinary projects. B...
Scientists from Tokyo Metropolitan University have discovered that charged states made of two electrons and a positively charged hole (or vice versa) on atomically thin rolls of carbon atoms have a structure-derived "handedness" in how they interact with light. While electron-hole pairs, or "exc...
The bacterial flagellum is a motility organelle that enables bacteria to swim and is composed of more than 30 different proteins. Researchers have long sought to understand how this complex nanomachine self-assembles from many parts in the correct order and at the correct positions. In a study ...
It began with an incident at an American Diabetes Association conference. Now a resulting boycott has caused a scientific slowdown, with no end in sight.
Geologists have uncovered new evidence that dramatic sea-level changes carved giant underwater canyons in South Australia's Flinders Ranges hundreds of millions of years ago, helping to create conditions that preserved some of the earliest complex life on Earth. The findings, led by Adelaide Uni...
Crop residues—the stems, leaves and husks left behind after harvesting cereals—could provide an important source of renewable energy for Europe, but research led by the University of Surrey suggests that removing too much from fields could come at a cost to biodiversity.
