Feb. 5, 2016 — Cells are not uniform spheres; they generally come in a variety of disparate shapes. In the broadest sense, this variation in shapes is known as cell polarity, and it is an essential property for a ... read more

Feb. 4, 2016 — Scientists have discovered a new option to control properties of the interface between the two layers, for instance the amount of charge transferred from one layer to the other or the emergence of ... read more

Feb. 3, 2016 — By creating and using the first optical attosecond pulse, scientists measured the time it takes electrons inside atoms to respond to the electromagnetic forces of ... read more

Feb. 3, 2016 — Scientists have grown organic crystals that allow creating flexible electronic ... read more

Physicists Create Artificial 'Graphene'

Feb. 2, 2016 — Physicists have created an artificial material with a structure comparable to ... read more

Feb. 2, 2016 — Scientists have now presented the smallest human-made lattice structure. Its struts and braces are made of glassy carbon. They are smaller than comparable metamaterials by a factor of five. The small ... read more

Feb. 1, 2016 — New transparent metamaterials under development could make possible computer chips and interconnecting circuits that use light instead of electrons to process and transmit data, representing a ... read more

Feb. 1, 2016 — Researchers have created the world's smallest integrated optical switch. Applying a small voltage causes an atom to relocate, turning the switch on or ... read more

Feb. 1, 2016 — When cold milk is poured into a hot cup of tea, a temperature equilibrium is reached very quickly. The milk droplets and the tea particles interact, and after a few moments they all have the same ... read more

Unconventional Superconductivity Near Absolute Zero Temperature

Feb. 1, 2016 — An important mechanism for superconductivity in a metallic compound containing ytterbium, rhodium and silicon, has been uncovered by researchers. The underlying concept of the quantum-critical point ... read more

Feb. 1, 2016 — The end of Moore's Law -- the prediction that transistor density would double every two years -- was one of the hottest topics in electronics-related discussions in 2015. Silicon-based ... read more

Spin Dynamics in an Atomically Thin Semi-Conductor

Feb. 1, 2016 — The mechanisms for spin motion in molybdenum disulfide, an emerging two-dimensional (2D) material, have been established by researchers. Their discovery resolves a research question on the properties ... read more

Jan. 30, 2016 — Researchers assumed that tiny objects would instantly blow up when hit by extremely intense light from the world’s most powerful X-ray laser. But to their astonishment, these nanoparticles ... read more

Jan. 29, 2016 — Researchers have observed polar vortices in a ferroelectric material that appear to be the electrical cousins of magnetic skyrmions. This discovery holds intriguing possibilities for advanced ... read more

Jan. 29, 2016 — The iron Fe2+ atom embedded in a semiconductor exhibits a single non-degenerate ground state of zero magnetic moment. A team of scientists has demonstrated that by using sufficiently large strain it ... read more

Plasma Accelerator Research Station Taking Shape

Jan. 29, 2016 — Particle accelerators find many applications in fundamental research, as well as in health, energy and security applications. They range from relatively compact, sometimes even table top devices to ... read more

Is the Neutrino Its Own Antiparticle?

Jan. 29, 2016 — Almost every particle has an antimatter counterpart: a particle with the same mass but opposite charge, among other qualities. But certain characteristics of neutrinos and antineutrinos make ... read more

Jan. 28, 2016 — Imagine a polymer with removable parts that can deliver something to the environment and then be chemically regenerated to function again. Or a polymer that can contract and expand the way muscles ... read more

Jan. 28, 2016 — Physicists have made a surprising discovery that the arrangement of atomic nuclei spins helps bring about superconductivity in ytterbium dirhodium disilicide, one of the most-studied materials in a ... read more

Jan. 28, 2016 — In the production of margarine, millions of tons of unsaturated fatty acids are converted from vegetable oils using hydrogen. While searching for improved catalysts for these so-called hydrogenation ... read more
