With measures aimed at reducing the emission of pollutants such as ammonia, policy makers pay too little attention to the consequences for the emission of other substances. This is revealed in a computer model constructed by Corjan Brink from Wageningen University during his doctoral research. For example, the model shows that reducing the amount of ammonia emitted leads to an increase in the emission of nitrous oxide (laughing gas).
The computer model developed by the environmental economist Brink, combined with figures from European agriculture demonstrates that the policy aimed at reducing ammonia emission can lead to an increased emission of nitrous oxide or methane. For example, ammonia-limiting measures such as the introduction of low-emission stables and the low-emission application of manure can lead to a tripling in the emission of nitrous oxide.
The results also indicate that a reduction in nitrous oxide or methane results in a reduced emission of ammonia. However, lower nitrous oxide emissions are associated with an increased emission of methane. The outcomes per country differ considerably, dependent on the measures implemented to reduce the emissions.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
