A team of international researchers led by the Plasma Science and Fusion Technology Laboratory of the University of Seville, have demonstrated the key role that energetic particles play in the stability of a tokamak plasma edge. The findings have been published in Nature Physics and could be key for the design of compact fusion power plants.
Epithelial tissues are in constant interaction with their environment. Maintaining their functionality requires dynamic balance (homeostasis) and that their cell numbers are tightly regulated. This is achieved by cell extrusion programs, a checkpoint mechanism eliminating unwanted or harmful cells. Researchers at the Max-Planck-Zentrum für Physik und Medizin (MPZPM), Institut Jacques Monod (CNRS, UP Cité, France) and Niels Bohr Institute (Denmark) have now demonstrated how physical signals can have an impact on the fate of extruding cells governing their death or survival. The results recently published in “Nature Physics” may establish novel paths for understanding tissue properties in both normal and pathological conditions.
Quantum computers require extreme cooling to perform reliable calculations. One of the challenges preventing quantum computers from entering society is the difficulty of freezing the qubits to temperatures close to absolute zero. Now, researchers at Chalmers University of Technology, Sweden, and the University of Maryland, USA, have engineered a new type of refrigerator that can autonomously cool superconducting qubits to record low temperatures, paving the way for more reliable quantum computation.
Researchers at Åbo Akademi University in Finland have identified and eliminated a previously unknown loss mechanism in organic solar cells that makes them more efficient and gives them a longer lifetime. The results provide new insight into how efficiency and stability can be increased in the future.
