The World Health Organization published a monograph "Environmental Health Criteria-Extremely Low-frequency Electromagnetic Fields" in 2007 as a conclusion of the international project which started in 1996, and issued guidelines and recommendations on the measures to protect people exposed to the electromagnetic fields from high voltage power lines and electric appliances. The International Agency for Research on Cancer labeled the low frequency electromagnetic fields into the category "2B" meaning possibly carcinogenic to humans mainly based on epidemiologic studies worldwide which indicated an increased risk of childhood leukemia without any concrete evidence from animal and cell biology studies. The results of such epidemiologic study carried out in Japan are described here together with summary comments on the Environmental Health Criteria.

Novel amphiphilic π-conjugated polymer nanoparticles tailored to efficiently absorb in the near-infrared II (NIR-II) region of the electromagnetic spectrum (>1000 nm) are presented. To achieve this, it is statistically introduced triethylene glycol substituted bithiophene moieties in various contents into a polymer backbone consisting of alternating thiophene and [1,2,5]thiadiazolo[3,4-g]quinoxaline. Through systematic modifications of monomer ratios, four amphiphilic conjugated polymers are produced.

Objectives: To systematically review and conduct a meta-analysis of studies on peripheral magnetic stimulation (PMS) for fibromyalgia (FM) treatment.
Methods: MEDLINE, EMBASE, CENTRAL, CINHAL, Web of Science, and ProQuest databases were searched from inception to July 2023 for studies in adult patients with FM treated with PMS. Studies using transcranial magnetic stimulation were excluded.

The bidirectional interactions between metamaterials and artificial intelligence have recently attracted immense interest to motivate scientists to revisit respective communities, giving rise to the proliferation of intelligent metamaterials and metamaterials intelligence. Owning to the strong nonlinear fitting and generalization ability, artificial intelligence is poised to serve as a materials-savvy surrogate electromagnetic simulator and a high-speed computing nucleus that drives numerous self-driving metamaterial applications, such as invisibility cloak, imaging, detection, and wireless communication. In turn, metamaterials create a versatile electromagnetic manipulator for wave-based analogue computing to be complementary with conventional electronic computing.
