The present invention provides a multi-load wireless power transfer system based on high-order Anti-PT symmetry. By introducing a “W-shaped” anti-resonance mode into a basic WPT platform, an effective Anti-PT non-Hermitian system is conveniently constructed. The “level attraction” of the anti-resonance mode is combined with the “level splitting” of the anti-resonance mode and the resonance mode, to study the “level pinning” effect of high-order Anti-PT symmetry. Compared with the traditional resonant WPT, the anti-resonant WPT has higher security, stability, transfer efficiency, and flexibility. Considering the miniaturization and integration of devices, a “meta coil” is designed by using a “synthetic dimension”, and used to construct a high-order Anti-PT symmetric system, thereby achieving multi-load efficient WPT. The new WPT technology based on the “level pinning” effect of high-order Anti-PT symmetry provides a good application research platform for enriching non-Hermitian physics.

N6-methyladenosine (m6A) is the most abundant internal modification on mammalian messenger RNA (mRNA). It is installed by a writer complex and can be reversed by erasers such as the fat mass and obesity-associated protein FTO. Despite extensive research, the primary physiological substrates of FTO in mammalian tissues and development remain elusive. Aspects disclosed show that FTO mediates m6A demethylation of long-interspersed element-1 LINE1 RNA in mouse embryonic stem cells (mESCs), regulating LINE1 RNA abundance and the local chromatin state, which in turn modulates transcription of LINE1-containing genes. FTO-mediated LINE1 RNA m6A demethylation also plays regulatory roles in shaping chromatin state and gene expression during mouse oocyte and embryonic development. FTO overexpression is also disclosed to modulate fertility.
