A team from UNIGE shows that it is possible to determine the state of a quantum system from indirect measurements when it is coupled to its environment.
A team of scientists has overcome a major challenge in predicting how Antarctic life will fare under future climate scenarios, revealing five scenarios for the future of Antarctic life.
A new unified theory connects two fundamental domains of modern quantum physics: It joins two opposite views of how a single exotic particle behaves in a many-body system, namely as a mobile or static impurity among a large number of fermions, a so-called Fermi sea.
The ice in a domestic freezer is remarkably different from the single crystals that form in snow clouds, or even those formed on a frozen pond. As temperatures drop, ice crystals can grow in a variety of shapes: from stocky hexagonal prisms to flat plates, to Grecian columns.
Digital and online technologies have made our workplace routines faster and easier. They have also made it easier for managers to keep tabs on workers, via monitoring apps designed to capture whether employees are "working hard, or hardly working."
Artificial light at night extends pollen season and increases allergen exposure in Northeastern United States cities. Lin Meng and colleagues analyzed 12 years of pollen data from 12 monitoring stations across the Northeastern United States, combining measurements with satellite data on artificial light at night and climate records. The study is published in PNAS Nexus.
Women perceive artificial intelligence (AI) as riskier than men do, according to a study. Beatrice Magistro and colleagues hypothesized that women are both more exposed to risk from AI and are more averse to risk in general than men. Their work was published in PNAS Nexus.
Incorporating living conditions and job opportunities in cities into mathematical models of human mobility improves model accuracy. The traditional gravity model of human mobility uses the distance of a move and the population of a destination city to predict migration patterns, with larger cities exerting more "pull" than smaller cities. The competing radiation model is based on quantifying the opportunity available in a destination location.
Some time around 1683, amateur Dutch scientist Antonie van Leeuwenhoek scraped the plaque from between his teeth and peered at it through a home-made microscope.
Researchers at the John Innes Center and the Earlham Institute are pioneering powerful single-cell visualization techniques that could unlock higher yields of global wheat.
