Atomic-scale magnetic patterns resembling a hedgehog's spikes could result in hard disks with massively larger capacities than today's devices, a new study suggests. The finding could help data centers keep up with the exponentially increasing demand for video and cloud data storage.

The trade-off between carrier mobility and stability in amorphous oxide semiconductor-based thin film transistors (TFTs) has been finally overcome by researchers in an ingeniously fabricated indium tin zinc oxide TFT. This could pave the way for the design of display technologies that are cheaper than current silicon-based technologies.

Researchers have made a breakthrough that should help pave the way for greatly improved control over the formation of quantum bits or qubits, the basic unit of quantum information technology.

Since the discovery of low-temperature superconductors, there has been an ongoing effort to realize superconductivity at room temperatures with low cooling costs. Crystalline materials containing hydrogen have shown promise on this front. Now, a global team of researchers have performed simulations to predict new crystal structures with hydrogen atoms as potential high-temperature superconductors, opening doors to energy-efficient technologies with lossless power transmission.
