Ferromagnetism can be induced electrically at room temperature

Inducing and controlling magnetization in ferromagnetic semiconductors using electric rather than magnetic fields could lead to smaller and more energy-efficient spintronic devices. Until now, however, this electrical control has only been achieved at cryogenic temperatures in magnetic semiconductors. Scientists in Japan have now extended electrical control all the way up to ambient temperature in cobalt-doped titanium dioxide, paving the way for room-temperature spintronics.

Researchers make visible the structure of the smallest crystals

A radical new way of making structures visible at the nano level has been developed at Johannes Gutenberg University Mainz. This new method makes it possible to determine with precision the arrangement of atoms and molecules in a diverse range of materials from cement to pharmaceuticals.

Technology funding makes climate protection cheaper

To cost-effectively protect the climate, not only an emissions trading scheme but also financial support for new technologies is needed. Economising on targeted funding, for example for renewable energies, makes climate protection more expensive - as scientists of the Potsdam Institute for Climate Impact Research now calculated for the first time, using a complex computer simulation that spans the entire 21st century.

A new way to go from nanoparticles to supraparticles

Controlling the behavior of nanoparticles can be just as difficult trying to wrangle a group of teenagers. However, a new study has given scientists insight into how tweaking a nanoparticle's attractive electronic qualities can lead to the creation of ordered uniform supraparticles'.

Nanowires a step towards photonic chip

Australian researchers have engineered one of the world's smallest ever nanowires for the next generation of telecommunication technology, bringing them one step closer to the holy grail of optics - the creation of a 'photonic chip' which would lead to a faster, more sustainable internet.

I'm a Scientist - the Film (w/video)

Stephen Curry has made a film by interviewing six scientists who are at different stages of their careers. They were kind enough to share their stories of how they got into science and to talk about why they like doing it and what they think it takes to be a good scientist.

Why carbon nanotubes spell trouble for cells

Scientists have shown that certain nanomaterials, such as carbon nanotubes, enter cells tip-first and almost always at a 90-degree angle. The orientation ends up fooling the cell; by taking in the rounded tip first, the cell mistakes the particle for a sphere, rather than a long cylinder. By the time the cell realizes the material is too long to be fully ingested, it's too late.
