 | | |  Silica nanoparticles dampen early allergy signals in mouse mast cells This in vitro study found that negatively charged SiO2 nanoparticles suppressed antigen-induced degranulation and activation-marker changes in IgE-sensitized mouse bone marrow-derived mast cells. By contrast, mTiO2 nanoparticles showed cytotoxic and pro-inflammatory effects, including enhanced DNP-induced IL-6 release, suggesting nanoparticle composition can shape early allergic immune responses. | | | | |  How nanotechnology could solve dermatology’s biggest delivery problem Nanotechnology is reshaping dermatology by improving drug delivery, photoprotection, barrier repair, follicular targeting, and antimicrobial activity across conditions such as acne, psoriasis, atopic dermatitis, wounds, alopecia, and photoaging. However, the review stresses that clinical translation remains limited by formulation instability, heterogeneous evidence, insufficient long-term safety data, and inconsistent regulatory standards. | |

| | | | |  A novel wireless chest patch enables continuous monitoring of stress signals, enhancing psychophysiological assessment in clinical and real-world settings. | | | | |  The review finds that several candidate biomarkers may help estimate fruit and vegetable intake more objectively than self-reported dietary tools, but most remain limited by specificity, sampling burden, supplement use, or incomplete validation. | | | | |  Detecting melanoma before it becomes visible is a major challenge in dermatology. Now, with researchers from Université de Montréal, scientists at Université du Québec's Institut national de la recherche scientifique (INRS) have developed a promising solution. | | | | |  A new Nature Communications study, published May 19, redefines scientists' understanding of how a popular class of antibiotics work. | | | | |  Scientists at the Garvan Institute of Medical Research have captured, for the first time, 'housekeeping' immune cells actively attacking and engulfing live melanoma cells – a discovery that could change the way we approach treatment for one of Australia's most common and deadly cancers. | | | | | When it comes to cancer, tumor suppressor genes are usually thought of as the "good guys." These genes make proteins that protect and repair DNA in cells. | | | | | Scientists and physicians should advocate to protect the vaccine research infrastructure that has saved an estimated 154 million lives over the past 50 years, according to a new commentary by researchers at Weill Cornell Medicine and the University of Washington. | |
