Testing hypotheses about the role of neural circuits in insect associative learning
To adapt to their environment and learn from past experiences, animals need to learn to associate stimuli in their environment (e.g., a particular sound or scent) and the rewards or threats that...
Investigating the role of ventral pallidum neurons in the basal ganglia
The basal ganglia (BG) are a group of subcortical brain nuclei that control automatic behavior in humans and other animal species. The BG has been found to show peculiar activity in people affected...
Highly efficient solution-processed upconversion photodetectors based on quantum dots
Researchers at ShanghaiTech University, the University of Toronto and the Chinese Academy of Sciences have recently developed new solution-processed upconversion photodetectors, which are a class of...
Simultaneously tuning the surface structure and oxidation state of copper catalysts
Electrical energy derived from renewable sources could be used to rearrange bonds in carbon dioxide (CO2) and water molecules into complex hydrocarbons, which can then be burnt to produce new energy...
A quantum metasurface that can simultaneously control multiple properties of light
Metasurfaces are artificial materials designed at the nanoscale, which can control the scattering of light with exceptionally high precision. Over the past decade or so, these materials have been...
A new material to print mechanically robust and shape-shifting structures
In recent years, 3-D printing has opened up interesting new possibilities for the large-scale production of electronic components, as well as of a variety of other objects. To this end, research...
Teaching the iCub robot to express basic human emotions
As robots make their way into a variety of environments and start interacting with humans on a regular basis, they should be able to communicate with users as effectively as possible. Over the past...
Research identifies detection constraints for dark photons
Past cosmological and astrophysical observations suggest that over one quarter of the universe's energy density is made up of a non-conventional type of matter known as dark matter. This type of...
A perovskite-based diode capable of both light emission and detection
Light sources and detectors are key components of countless technological devices on the market today. For instance, light emitting diodes (LEDs) are often used as a source of light in displays and...
First successful laser trapping of circular Rydberg atoms
Rydberg atoms, which are atoms in a highly excited state, have several unique and advantageous properties, including a particularly long lifetime and large sensitivities to external fields. These...
