Date Time Share Chinese Academy of Sciences Recently, researchers from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences (CAS) have revealed the competitive behavior of bound electrons and free electrons in Epsilon-Near-Zero (ENZ) materials irradiated by ultrafast laser pulses. They proposed the principle and method of synchronously tailoring the saturated absorption (SA) and reverse saturated absorption (RSA) of ENZ materials, which greatly broadened the ability to control the nonlinear optical response at the ENZ wavelength. Relevant study has be...

The lines... view more  Credit: Yiyong Zhao, Chien-Hsun Huang, and Hong Ma The most comprehensive study of the family tree for legumes, the plant family that includes beans, soybeans, peanuts, and many other economically important crop plants, reveals a history of whole-genome duplications. The study also helps to uncover the evolution of genes involved in nitrogen fixation--a key trait l...

Cd86), were down-regulated in Mettl3-deficient cells (Fig. 1G), suggesting that METTL3 has a critical function in controlling the innate immune response of Raw 264.7 macrophages. To further confirm the biological role of the m 6A modification in macrophages, Mettl3 conditional KO (CKO) mice were generated by crossing Mettl3 flox/flox mice with mice expressing Cre recombinase under the control of lysozyme 2 promoter ( Lyzm-Cre). We have documented the loss of both the METTL3 protein and the overall m 6A modification in bone marrow–derived macrophages (BMDMs) from Mettl3 flox/flox; Lyzm-C...
