Jun 10, 2024 (Nanowerk News) Researchers worldwide can now create highly realistic brain cortical organoids — essentially miniature artificial brains with functioning neural networks — thanks to a proprietary protocol released this month by researchers at the University of California San Diego. The new technique, published in Nature Protocols ("Generation...
Nanoparticles reprogram mouse immune systems to suppress food allergy
Jun 10, 2024 (Nanowerk News) Two doses of allergen-encapsulating nanoparticles delivered intravenously prevented anaphylaxis during a food allergy test in mice, according to a study led by University of Michigan researchers. The results, published in Advanced Healthcare Materials ("Allergen-encapsulating nanoparticles reprogram pathogenic allergen-specific Th2 cells to suppress food allergy"), offer...
Many nearby star clusters originate from only three ‘families’
Jun 10, 2024 (Nanowerk News) An international team of astronomers led by the University of Vienna has deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team, led by Cameren Swiggum and João Alves from the University of...
The solar system may have passed through dense interstellar clouds 2 million years ago, altering Earth’s climate
Jun 10, 2024 (Nanowerk News) Around two million years ago, Earth was a very different place, with our early human ancestors living alongside saber-toothed tigers, mastodons, and enormous rodents. And, depending on where they were, they may have been cold: Earth had fallen into a deep freeze, with multiple ice...
Miniaturizing a laser on a photonic chip
Jun 10, 2024 (Nanowerk News) Lasers have revolutionized the world since the 60’s and are now indispensable in modern applications, from cutting-edge surgery and precise manufacturing to data transmission across optical fibers. But as the need for laser-based applications grows, so do challenges. For example, there is a growing market...
