Scientists have discovered a long-predicted magnetic state of matter called an antiferromagnetic excitonic insulator -- broadly speaking, a novel type of magnet. Understanding the connections between electrons' 'spin' and charge in such materials could have potential for realizing new technologies.

Insect populations are plummeting worldwide, with major consequences for our ecosystems and without us quite knowing why. A new AI method is set to help monitor and catalog insect biodiversity, which until now has been quite challenging.

Physicists have learned to manipulate electrons in gigantic Rydberg atoms with such precision they can create 'synthetic dimensions' where the system acts as if it had extra spatial dimensions, which are important tools for quantum simulations.

The COVID-19 pandemic has presented both challenges and opportunities for medical training. Remote learning technology has become increasingly important in several fields. A new study finds that in a remote environment, an artificial intelligence (AI) tutoring system can outperform expert human instructors.

Researchers have applied the tools of neuroscience to study when and how an artificial neural network can overcome bias in a dataset. They found that data diversity, not dataset size, is key and that the emergence of certain types of neurons during training plays a major role in how well a neural network is able to overcome dataset bias.

New applications in energy, defense and telecommunications could receive a boost after a team created a new type of 'nanocrystal gel' -- a gel composed of tiny nanocrystals each 10,000 times smaller than the width of a human hair that are linked together into an organized network.

The combination of mathematical modeling and experiments identifies the difference in molecular clockworks of the master and slave clock neurons in Drosophila. This solves the long-standing mystery of the molecular mechanisms underlying how the circadian (~24h) clock can exhibit paradoxical characteristics of robustness (strong rhythms), and plasticity (flexible adaption).
