Vaccine-hesitant adults were more likely to consider getting a COVID-19 vaccine when public health messages acknowledged distrust of government and affirmed values such as personal liberty, a new study found.

An ultrasound-responsive micronanorobot combines a collagenase-secreting bacterium, bismuth ferrite nanoparticles, the drug DM4 and a targeting ligand to treat nonmuscle-invasive bladder cancer. After intravesical delivery, it degrades tumor matrix, enhances drug penetration, and ultrasound triggers reactive oxygen species, achieving 90.8% cell death in vitro and 82.4% tumor inhibition in mice. The system also promotes antitumor immunity, increasing CD8+ T-cell infiltration and shifting macrophages toward the M1 phenotype.

According to international studies, taking Acetylsalicylic acid daily can protect people with Lynch syndrome from developing colorectal cancer – even at low doses. Researchers from the University Hospital Bonn (UKB), the University of Bonn, and the Center for Integrated Oncology (CIO) Bonn, in collaboration with the self-help organization SemiColon, have now found that these scientific findings have so far been insufficiently incorporated into clinical practice. The results of the LYNX study have now been published as a letter in the journal *The Lancet Gastroenterology & Hepatology*.

Climate policy models usually assume people hold accurate beliefs about climate damages. A new study builds disinformation into a climate–economy model and finds that informed democratic majorities can deliver stronger carbon taxes than a politically constrained planner, but this advantage collapses abruptly once disinformation tips the majority. Late and persistent disinformation yields the most severe warming, while counter-disinformation efforts can largely restore effective policy.
