AI-powered apps offering medical diagnoses at the click of a button are often limited by biased data and a lack of regulation, leading to inaccurate and unsafe health advice, a new study found.

McGill University researchers presented symptom data from known medical cases to two popular, representative apps to see how well they diagnosed the conditions. While the apps sometimes gave correct diagnoses, they often failed to detect serious conditions, according to findings published in the Journal of Medical Internet Research. This potentially resulted in delayed treatment.

To plan their work more efficiently, companies need to identify those who enjoy teleworking versus those who find it less satisfying

CNR-INO researchers write a new review on quantum mixtures of ultracold gases under three different perspectives: systems made of a few atoms of different kinds, single impurities within a host gas and quantum mixtures of two interacting gases.

06 November 2024/Kiel. The eruption of the Hunga Tonga-Hunga Ha’apai submarine volcano in January 2022 released massive quantities of volcanic material into the ocean and atmosphere. Researchers from the GEOMAR Helmholtz Centre for Ocean Research Kiel have investigated how this has affected surface water biogeochemistry in the South Pacific. During a GEOTRACES expedition, the team showed that large amounts of trace elements, including iron, were introduced into the ocean with the volcanic material, fostering phytoplankton growth. This nutrient input could have a lasting effect on marine life and could increase the ocean's capacity to sequester CO₂. These findings have now been published in the journal Nature Communications.
