One-way street planned for heat

Physicists design material that conducts one way and insulates the other.

European physicists have sketched out a blueprint for a valve that lets heat pass only one way. The proposed material conducts heat flowing in one direction, but also behaves as an insulator, stopping it going the other way 1 .

In theory, a heat valve could keep parts of microelectronic circuitry cool or channel heat to chip-sized chemical reactors, which are currently being developed fo

Offshore wind technology ready for application

Offshore wind technology ready for application

The technology for the construction and operation of offshore windfarms is ready for large-scale application. Companies in the fields of engineering and services are preparing to take part. This can be seen in the conclusions of the project Concerted Action on Offshore Wind Energy in Europe (CA-OWEE) of the European Union, in which seventeen parties from thirteen European countries have brou

Ceramic research reaches new heights

Materials scientists at the University of Wales Aberystwyth (UWA) are taking ceramics to new heights in order to determine the structure and stability of the materials which are used to construct aeroplane engines and the tiles for the space shuttle.

Dr Rudi Winter and colleagues from the Department of Physics at UWA are using a unique combination of techniques to study the materials at extreme temperatures which simulate those experienced when aircraft travel at high speed or when they dec

Dodo flew to its grave

Ancestors of the flightless figurehead of extinction island-hopped.

The flightless dodo’s ungainly shape hid an island-hopping past, say researchers. DNA from the extinct bird has revealed its place in the pigeon family tree, and suggests how it came to end up on its home, and graveyard, the island of Mauritius 1 .

The dodo’s strange appearance led to centuries of wrangling over its ancestry. “It’s the figurehead of extinction, yet little is known about its e

Magic bullet homes in

New candidate cancer drug does damage only in tumours.

A new drug turns lethal only when it reaches cancer cells. In healthy cells it is harmless. Though not yet shown to work in humans, it is a step towards a magic bullet to knock out tumour cells selectively, with minimal side effects.

The drug works in mice implanted with human tumours, say chemists Lutz Tietze and colleagues at the University of Gottingen in Germany. Before being treated with the drug, the mice are giv

Ideas about Early Solar System Development May Need Revision

A new analysis of the mineral composition of meteorites suggests that theories concerning the development of the early solar system may need revision. Announcing their results today in the journal Science, researchers conclude that it took the earth only 20 million years to form from material floating around the early sun. Previous estimates, in contrast, had placed that figure at around 50 million years. The findings also re-open the debate over which types of supernovae could have produced our sola
