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-Cre mice (fig. S1I). No differences in the frequency of major immune cell populations were observed between

The provenance of oxygen on Earth and other solar planetary bodies is a fundamental issue. It is widely accepted that the prebiotic pathway of oxygen production in the Earth primitive atmosphere was via vacuum ultraviolet (VUV) photodissociation of CO
2 and subsequent recombination of two O atoms.
In contrast, the photodissociation of H2O, one of the dominant oxygen carriers, has long been assumed to proceed mainly to produce hydroxyl (OH)- and hydrogen (H)-atom primary products, and its contribution to oxygen production is limited.

Researchers have developed a brain-like computing device that is capable of learning by association.
Similar to how famed physiologist Ivan Pavlov conditioned dogs to associate a bell with food, researchers at Northwestern University and the University of Hong Kong successfully conditioned their circuit to associate light with pressure.
The research will be published April 30 in the journal
Nature Communications.
The device s secret lies within its novel organic, electrochemical synaptic transistors, which simultaneously process and store information just like the human brain. The researchers demonstrated that the transistor can mimic the short-term and long-term plasticity of synapses in the human brain, building on memories to learn over time.
