Rate of scientific breakthroughs slowing over time: Study

The rate of ground-breaking scientific discoveries and technological innovation is slowing down despite an ever-growing amount of knowledge, according to an analysis released Wednesday of millions of research papers and patents.

Quantum leap for research into unhackable communications networks

Scientists at Heriot-Watt University in Edinburgh, Scotland, have published new research into the phenomenon known as quantum entanglement. This is when two particles—such as photons of light—remain connected even when ...

Microscopic chains that mimic DNA

Circular polycatenanes are chains that can move and change shape: they twist, stretch and wrap around themselves. Three physicists of the European Eutopia Cost network, coordinated by UniTrento, have dedicated themselves ...

A new quantum component made from graphene

Less than 20 years ago, Konstantin Novoselov and Andre Geim first created two-dimensional crystals consisting of just one layer of carbon atoms. Known as graphene, this material has had quite a career since then.

Color-selective, three-dimensional polarization structures

Polarization has been a central concept to our understanding of optics and has found many applications ranging from quantum science to our daily life. 3D polarization structures possess peculiar optical features and extra ...
