Nanoparticle with mRNA appears to prevent, treat peanut allergies in mice
Apr 05, 2023 (Nanowerk News) Peanut allergies affect 1 in 50 children, and the most severe cases lead to a potentially deadly immune reaction called anaphylactic shock. Currently, there is only one approved treatment that reduces the severity of the allergic reaction, and it takes months to kick in. A...
Using dark matter distribution to test our cosmological model
Apr 04, 2023 (Nanowerk News) An international team of astrophysicists and cosmologists at various institutes including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) have submitted a set of five papers, measuring a value for the “clumpiness” of the universe’s dark matter, known to cosmologists...
Efficient nanostructuring of glass with elliptically polarized pulses
Apr 04, 2023 (Nanowerk News) Photoexcitation, particularly photoionization, represents a vital aspect of light-matter interactions in nature, with applications spanning photosynthesis in plants, vision in biology, photography, and laser processing of materials. Conventional wisdom posits that the transformation of a substance is weaker when less light is absorbed. However, our...
