In today’s science and business worlds, it’s increasingly common to hear that solving big problems requires a big team. But a new analysis of more than 65 million papers, patents and software projects found that smaller teams produce much more disruptive and innovative research.

Direct-write quantum calligraphy in monolayer semiconductors
Scientists at the U.S. Naval Research Laboratory (NRL) and the Air Force Research Laboratory (AFRL) have developed a way to directly write quantum light sources, which emit a single photon of light at a time, into monolayer semiconductors such as tungsten diselenide (WSe2). Single photon emitters (SPEs), or quantum emitters, are key components in a wide range of nascent quantum-based technologies, including computing, secure communications, sensing and metrology.

Scientists develop first fabric to automatically cool or insulate depending on conditions
Despite decades of innovation in fabrics with high-tech thermal properties that keep marathon runners cool or alpine hikers warm, there has never been a material that changes its insulating properties in response to the environment. Until now. Continue reading “Scientists develop first fabric to automatically cool or insulate depending on conditions”
Laser physics: Attosecond photoelectron spectroscopy accelerated
Laser physicists have succeeded in reducing the acquisition time for data required for reliable characterization of multidimensional electron motions by a factor of 1000. Continue reading “Laser physics: Attosecond photoelectron spectroscopy accelerated”
A cycle path made of plastic waste in Zwolle, Holland
The world’s first plastic bicycle path made of recycled bottles, cups and packaging has opened in the Netherlands, as part of a pilot that could see similar roads open up across the country. Continue reading “A cycle path made of plastic waste in Zwolle, Holland”
New insights into magnetic quantum effects in solids
Atoms and molecules in crystalline solids are arranged in regular three-dimensional lattices. The atoms interact with each other via various forces, finally reaching a state of minimum energy. Near absolute zero, the lattice oscillations freeze, so that interactions between electron spins dominate. A particularly interesting case occurs when the spins cannot all align at the same time to reach a state of lowest energy. This results in a frustrated system in which the spins are almost completely disordered and are therefore referred to as a spin liquid.
