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.

Superconductors and X-ray beams: the drawing shapes

An Italian-British team of scientists has succeeded in drawing superconducting shapes using an X-ray beam. The study shows how being able to create and control tiny superconducting structures could lead to innovative electronic devices.
