Their experimental results shed new insights into recent debates regarding the evolution of the band structure with temperature in these materials, which exhibit unusual quantum phenomena and are envisioned to be crucial in next-generation electronics, spintronics, and quantum computers. • Email to a friend • Dynamic tattoos promise to warn wearers of health threats You can't walk into a doctor's office and get a dynamic tattoo yet, but they are on the way. Early proof-of-concept studies provide convincing evidence that tattoos can be engineered, not only to change color, but to sense and convey biomedical information, including the onset of cancer. • Email to a friend • The groove of the self-organized active nematic ribbon Researchers report the creation of a 3D active nematic. The material passes through several spatial patterns, from collapsing into a ribbon to wrinkling in 3D. • Email to a friend • Scientists take a 'spin' onto magnetoresistive RAM Magnetoresistive random access memory (MRAM) is the forerunning candidate for the next generation digital technology. However, manipulating MRAM efficiently and effectively has been challenging. A revolutionary breakthrough generates spin current to switch the pinned magnetic moments at will. • Email to a friend • 'Stretching rack' for cells An ingenious device, only a few micrometers in size, enables to study the reaction of individual biological cells to mechanical stress. • Email to a friend • The return of the spin echo Multiple echoes as a result of a strong link between spins and microwave photons - this effect presents exciting, new opportunities for working with quantum information. • Email to a friend • White graphene: high defect tolerance and elasticity unveiled by nanomechanics experts After revealing the realistic strength and stretchability of graphene, researchers have carried forward the success by unveiling the high defect tolerance and elasticity of hexagonal boron nitride (h-BN), another 2D material known as 'white graphene'. This follow-up study will promote future development and applications of strain engineering, piezoelectronics and flexible electronics. • Email to a friend • Researchers develop smallest particle sensor in the world With this innovation, smartphones, smart watches or fitness wristbands can for the first time measure the quality of the ambient air in real time and sound the alarm in the event of increased fine dust values. • Email to a friend • New brain cell-like nanodevices work together to identify mutations in viruses These systems could potentially overcome computational hurdles faced by current digital technologies. • Email to a friend • More Recent Articles Magnetic 'T-Budbots' made from tea plants kill and clean biofilms (w/video) Nanoscale vortices with a unique property A multishot lensless camera in development could aid disease diagnosis The world's smallest 'refrigerator' can only be seen through an electron microscope New materials: A toggle switch for catalysis
