The strategy developed at the University of São Paulo uses magnetic nanoparticles that bind to tiny plastic particles and permit their removal with the aid of a magnet.

We are thrilled to announce that the Digital Olfaction Summit (DOS) 2024 will take place this December 5-6 in Tokyo, bringing together researchers, innovators, and practitioners from around the world to showcase the future of Digital Olfaction (DO). This prestigious event invites participants to present short oral presentations, share research in poster sessions, and conduct live demonstrations that highlight the latest advancements in the field.

Live Demonstrations: Experience firsthand how DO technologies are evolving, with real-world applications in healthcare, food and beverage, environmental monitoring, and more.

SAN ANTONIO — November 12, 2024 — A Southwest Research Institute-led team combined compositional data of primitive bodies like Kuiper Belt objects, asteroids and comets with new solar data sets to develop a revised solar composition that potentially reconciles spectroscopy and helioseismology measurements for the first time. Helioseismology probes the Sun’s interior by analyzing the waves that travel through it, while spectroscopy reveals the surface composition based on the spectral signature produced by each chemical element.  

Roughly 90 million years ago, climatic conditions in Antarctica were suitable for resin-producing trees. A team of researchers led by the Alfred Wegener Institute and the TU Bergakademie Freiberg have just released a paper in the journal Antarctic Science, in which they describe the southernmost discovery of amber in the world.

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming the popular hypothesis that invisible dark matter helped the earliest stars and galaxies clump together.
