Experts develop nanolasers on silicon

Researchers at Cardiff University have shown tiny light-emitting nanolasers less than a tenth of the size of the width of a human hair can be integrated into silicon chip design.

Not all ions in tokamaks go with the flow

For the first time, scientists are measuring the rotation of the main (deuterium) plasma in the edge region of a fusion device. New spectroscopic measurements combined with state-of-the-art spectroscopic simulation made this ...

Butterflies thrive in grasslands surrounded by forest

For pollinating butterflies, it is more important to be close to forests than to agricultural fields, according to a study of 32,000 butterflies by researchers at Linköping University and the Swedish University of Agricultural ...

Understanding insulators with conducting edges

Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists at Goethe University have now modelled ...

Video: Artificial intelligence putting an end to poaching

When placed in protected areas, the TrailGuard artificial intelligence camera uses AI inference at the edge to detect possible poachers and alert park rangers in near real-time, allowing them to take action before animals ...

Holey graphene as Holy Grail alternative to silicon chips

Graphene, in its regular form, does not offer an alternative to silicon chips for applications in nanoelectronics. It is known for its energy band structure, which leaves no energy gap and no magnetic effects. Graphene antidot ...

The importance of 'edge populations' to biodiversity

More than two-thirds of Canada's biodiversity is made up of species that occur within the country's borders only at the very northern edge of their range. Biologists have long debated how much effort should be dedicated to ...

The best laptops of 2018

In almost every dorm room, library, coffee shop, office and airport around the world, you will find someone with their head buried in a laptop.
