New method of producing nanomagnets for information technology

An international team of researchers has found a new method of producing molecular magnets. Their thin layer systems made of cobalt and an organic material could pave the way for more powerful storage media as well as faster and more energy-efficient processors for information processing. The results of this research have been published in the current issue of the renowned journal Nature.

Putting the squeeze on cells: By deforming cells, researchers can deliver RNA, proteins and nanoparticles for many applications

Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins that can reprogram them into pluripotent stem cells. Researchers have now found a safe and efficient way to get large molecules through the cell membrane, by squeezing the cells through a narrow constriction that opens up tiny, temporary holes in the membrane.

Self-assembling silica microwires may herald new generation of integrated optical devices

Silica microwires are the tiny and as yet underutilized cousins of optical fibers. If precisely manufactured, however, these hair-like slivers of silica could enable applications and technology not currently possible with comparatively bulky optical fiber. By carefully controlling the shape of water droplets with an ultraviolet laser, a team of researchers has found a way to coax silica nanoparticles to self-assemble into much more highly uniform silica wires.

Quantum States Between Order and Disorder

With his research on quantum states in the realm between order and disorder, one professor's work has raised quite a stir; ultra cold atom clouds with a high degree of order approach a disordered thermal equilibrium. During this transition they spend some time in an astonishingly stable intermediate state.

Revolutionary theory of dark matter

The universe abounds with dark matter. Nobody knows what it consists of. University of Oslo physicists have now launched a very hard mathematical explanation that could solve the mystery once and for all.
