No statistical methods were used to predetermine sample size. The experiments were not randomized and the investigators were not blinded to allocation during experiments and outcome assessment. Male heterozygous ythdf2+/− fish in the *AB background were custom made by ZGeneBio. TALEN mutagenesis was performed to mutate ythdf2 (Ensembl ENSDART00000127043) with L1 recognition sequence 5′-GGACCTGGCCAATCCCC-3′, R1 recognition sequence 5′-GGCACAGTAATGCCACC-3′, and spacer sequence 5′-TCCCAATTCAGGAATG-3′. Purchased fish were outcrossed to in-house wild-type *AB fish. Embryos were obtained from natural crosses, were raised under standard conditions, and were staged according to literature26. Embryos were reared at 28.5 °C and all experiments and observations were performed as close to this temperature as possible. Fish lines were maintained in accordance with AAALAC research guidelines, under a protocol approved by the University of Chicago IACUC (Institutional Animal Care & Use Committee). The open reading frame of zebrafish ythdf2 was purchased from Open Biosystems (clone 5601005) and subcloned into a pCS2+ vector using restriction enzyme sites of BamHI and XhoI. The resulting vector was linearized by HindIII and used as a template for ythdf2 probe preparation. Antisense digoxigenin (DIG) RNA probes were generated by in vitro transcription using standard reagents and methods. In situ hybridization protocol was followed essentially as previously reported27. All experiments were repeated at least once from biological samples. Control and ythdf2 morpholinos (5′-TGGCTGACATTTCTCACTCCCCGGT-3′) were obtained from Gene Tools (Oregon). 3 ng of either control or gene-specific morpholino was injected into *AB wild-type embryos at the one-cell stage. GFP and mCherry were subcloned into pCS2+ vectors and linearized by NotI. GFP-m6A, GFP-A, and mCherry-capped and polyadenylated mRNA was generated by in vitro transcription using mMessage mMachine SP6 kit (Thermo Fisher) and Poly(A) tailing kit (Thermo Fisher) according to the manufacturer’s protocol. Products were purified with the MEGAclear transcription clean-up kit (Thermo Fisher) and used for injections directly. For GFP-m6A, we spiked 6 nmol m6ATP into the 100 nmol ATP supplied in the transcription reaction, in order to ensure that less than 0.3% of GFP mRNAs are without m6A on average. (GFP mRNA is 942 nt; each mRNA has 1.89 m6A on average.) 35 pg of either GFP reporter mRNA and 10 pg of mCherry mRNA were injected together in 1.25 nl into embryos at the one-cell stage. ythdf2 mRNA containing the ythdf2 5′ UTR and a 3′ Flag tag, which was used to rescue the mutant phenotype and validate the knockdown efficiency of ythdf2 MO, was constructed in pCS2+ vector (forward primer: 5′-CGTACGGATCCTGTCTGATCTGCAGCTGTAG-3′; reverse primer: 5′-CGATGCTCGAGTTACTTGTCATCGTCGTCCTTGTAATCTATTCCAGATGGAGCAAGGC-3′) and prepared in the same way as mCherry mRNAs. Antibodies used in this study are listed below in the format of name (application; catalogue number; supplier): mouse anti-Flag HRP conjugate (Western; A5892; Sigma), rabbit anti-m6A (m6A-seq and m6A-CLIP-seq; 202003; Synaptic Systems), rabbit anti-histone H3 (IF; ab5176; Abcam), and anti-rabbit Alexa Fluor 488 (IF; ab150077; Abcam). All images were observed with a Leica MZFLIII microscope and captured with a Nikon D5000 digital camera using Camera Control Pro (Nikon) software. For fluorescent microscopy, standard ET-GFP and TXR LP filters (Leica) were used. For bright field imaging of live embryos, only saturation was adjusted and was adjusted identically for all images. For fluorescent imaging of live embryos, no image processing was performed. For fluorescent imaging of fixed embryos, contrast and exposure were adjusted for all to obtain the lowest amount of background while preserving the morphology of all visible nuclei. All experiments were repeated at least once from biological samples. To compare the total amount of DNA in wild-type and mutant embryos at different time points during the MZT, 10 embryos per time point per condition were dechorionated and pipetted into standard DNA lysis buffer. The number of embryos in each tube was counted twice to ensure uniformity. Proteinase K was added to 100 μg ml−1 and the embryos were incubated for 4 h at ~55 °C with occasional mixing. Proteinase K was inactivated by a 10-min incubation at 95 °C and the DNA was then phenol-chloroform-extracted, ethanol-precipitated, and resuspended in 100 μl Tris (pH 8.5) and 1 mM EDTA using standard procedures. Double-stranded DNA content was measured with NanoDrop. Three biological replicates (comprised of the offspring of three different fish mating pairs of the appropriate genotype) were measured for each time point for both the control and experimental samples. Biological replicates were averaged together to determine the average DNA amount per time point per genotype and to compute standard errors of the mean. All DNA values were normalized to that of wild-type embryos at 2.5 h.p.f. Embryos were collected into standard 2× protein sample buffer with added β-mercaptoethanol and protease inhibitors and immediately put on ice for a few minutes. The embryo mixtures were carefully but thoroughly pipetted up and down to dissolve and homogenize the embryos, and then samples were heated at 95 °C for 5 min and frozen at −80 °C. Before use, samples were again heated for 5 min and then centrifuged at 12,000 r.p.m. to remove debris. Supernatants were loaded into a 10-well, 1.5 mm Novex 4–20% Tris-Glycine Mini Protein Gel (Thermo Fisher) with 6 embryos per well. The gel was transferred onto a nitrocellulose membrane using iBlot2 gel transfer system (Thermo Fisher) set to P3 for 7 min with iBlot2 mini gel transfer stacks (Thermo Fisher). Membranes were blocked in 5% BSA, 0.05% Tween-20 in PBS for 1 h, and then incubated overnight at 4 °C with anti-Flag–HRP conjugate (Sigma) diluted 1:10,000 in 3% BSA. Proteins were visualized using the SuperSignal West Pico Luminol/Enhancer solution (Thermo Fisher) in FluorChem M system (ProteinSimple). mRNA isolation for LC-MS/MS: total RNA was isolated from zebrafish embryos with TRIzol reagent (Invitrogen) and Direct-zol RNA MiniPrep kit (Zymo). mRNA was extracted by removal of contaminating rRNA using RiboMinus Eukaryote Kit v2 (Thermo Fisher) for two rounds. Total RNA isolation for RT–qPCR: we followed the instruction of Direct-zol RNA MiniPrep kit (Zymo) with DNase I digestion step. Total RNA was eluted with RNase-free water and used for RT–qPCR directly. 100–200 ng of mRNA was digested by nuclease P1 (2 U) in 25 μl of buffer containing 10 mM of NH OAc (pH 5.3) at 42 °C for 2 h, followed by the addition of NH HCO (1 M, 3 μl, freshly made) and alkaline phosphatase (0.5 U). After an additional incubation at 37 °C for 2 h, the sample was diluted to 50 μl and filtered (0.22 μm pore size, 4 mm diameter, Millipore), and 5 μl of the solution was injected into LC-MS/MS. Nucleosides were separated by reverse-phase ultra-performance liquid chromatography on a C18 column with on-line mass spectrometry detection using an Agilent 6410 QQQ triple-quadrupole LC mass spectrometer in positive electrospray ionization mode. The nucleosides were quantified by using the nucleoside to base ion mass transitions of 282 to 150 (m6A), and 268 to 136 (A). Quantification was performed in comparison with the standard curve obtained from pure nucleoside standards running on the same batch of samples. The ratio of m6A to A was calculated on the basis of the calibrated concentrations9. Total RNA was isolated from fish embryos collected at different time points with TRIzol reagent and Direct-zol RNA MiniPrep kit. For each time point, ~200 embryos were collected to ensure RNA yield and that samples were representative. mRNA was further purified using RiboMinus Eukaryote Kit v2. RNA fragmentation was performed by sonication at 10 ng μl−1 in 100 μl RNase-free water using Bioruptor Pico (Diagenode) with 30 s on/off for 30 cycles. m6A-immunoprecipitation (IP) and library preparation were performed according to the previous protocol17. Sequencing was carried out on Illumina HiSeq 2000 according to the manufacturer’s instructions. Additional high-throughput sequencing of zebrafish methylome was carried out using a modified m6A-seq method, which is similar to previously reported methods19, 20. Briefly, total RNA and mRNA were purified as previously described for m6A-seq. Purified mRNA (1 μg) was mixed with 2.5 μg of affinity purified anti-m6A polyclonal antibody (Synaptic Systems) in IPP buffer (150 mM NaCl, 0.1% NP-40, 10 mM Tris-HCl (pH 7.4)) and incubated for 2 h at 4 °C. The mixture was subjected to UV-crosslinking in a clear flat-bottom 96-well plate (Nalgene) on ice at 254 nm with 0.15 J for 3 times. The mixture was then digested with 1 U μl−1 RNase T1 at 22 °C for 6 min followed by quenching on ice. Next, the mixture was immunoprecipitated by incubation with protein-A beads (Invitrogen) at 4 °C for 1 h. After extensive washing, the mixture was digested again with 10 U μl−1 RNase T1 at 22 °C for 6 min followed by quenching on ice. After additional washing and on-bead end-repair, the bound RNA fragments were eluted from the beads by proteinase K digestion twice at 55 °C for 20 and 10 min, respectively. The eluate was further purified using RNA clean and concentrator kit (Zymo Research). RNA was used for library generation with NEBNext multiplex small RNA library prep kit (NEB). Sequencing was carried out on Illumina HiSeq 2000 according to the manufacturer’s instructions. Total RNA was isolated from wild-type and mutant fish embryos collected at different time points with TRIzol reagent and Direct-zol RNA MiniPrep kit. For each time points, ~20 embryos were collected to ensure RNA yield and that samples were representative. mRNA was further purified using RiboMinus Eukaryote Kit v2. RNA fragmentation was performed using Bioruptor Pico as described previously. Fragmented mRNA was used for library construction using TruSeq stranded mRNA library prep kit (Illumina) according to manufacturer’s protocol. Sequencing was carried out on Illumina HiSeq 2000 according to the manufacturer’s instructions. All samples were sequenced by Illumina Hiseq 2000 with single-end 50-bp read length. The deep-sequencing data were mapped to zebrafish genome version 10 (GRCz10). (1) For m6A-seq, reads were aligned to the reference genome (danRer10) using Tophat v2.0.14 (ref. 28) with parameter -g 1–library-type = fr-firststrand. RefSeq Gene structure annotations were downloaded from UCSC Table Browser. The longest isoform was used if the gene had multiple isoforms. Aligned reads were extended to 150 bp (average fragments size) and converted from genome-based coordinates to isoform-based coordinates, in order to eliminate the interference from introns in peak calling. The peak-calling method was modified from published work18. To call m6A peaks, the longest isoform of each gene was scanned using a 100 bp sliding window with 10 bp step. To reduce bias from potential inaccurate gene structure annotation and the arbitrary usage of the longest isoform, windows with read counts less than 1 out of 20 of the top window in both m6A-IP and input sample were excluded. For each gene, the read counts in each window were normalized by the median count of all windows of that gene. A Fisher exact test was used to identify the differential windows between IP and input samples. The window was called as positive if the FDR < 0.01 and log (enrichment score) ≥ 1. Overlapping positive windows were merged. The following four numbers were calculated to obtain the enrichment score of each peak (or window): (a) reads count of the IP samples in the current peak or window, (b) median read counts of the IP sample in all 100 bp windows on the current mRNA, (c) reads count of the input sample in the current peak/window, and (d) median read counts of the input sample in all 100 bp windows on the current mRNA. The enrichment score of each window was calculated as (a × d)/(b × c). (2) For m6A-CLIP-seq, after removing the adaptor sequence, the reads were mapped to the reference genome (danRer10) using Bowtie2. Peak calling method was similar to the previous study19. Briefly, mutations were considered as signal and all mapped reads were treated as background. A Gaussian Kernel density estimation was used to identify the binding regions. The motif analysis was performed using HOMER29 to search motifs in each set of m6A peaks. The longest isoform of all genes was used as background. (3) For mRNA-seq, reads were mapped with Tophat and Cufflink (v2.2.1) was used to calculate the FPKM of each gene to represent their mRNA expression level30. (4) For fish gene group categorization, we used the input mRNA-seq data from m6A-seq. FPKM of all genes were first normalized to the highest value of five time points, with only genes with FPKM >1 analysed. Then Cluster3.0 (ref. 31) was used to divide all genes into six clusters, with the parameters: adjust data – normalize genes; k-means cluster – organize genes, 6 clusters, 100 number; k-means – Euclidean distance. The result clustered file with clustered number was merged with original FPKM values, imported and processed in R, and plotted in Excel. (5) For GO analysis, the list of target genes was first uploaded into DAVID32, 33 and analysed with functional annotation clustering. The resulting file was downloaded and extracted with GO terms and corresponding P values. The new list (contains GO terms with P < 0.01) was imported into REVIGO34 and visualized with the interactive graph, which was used as the final output figures. Methylated genes (at each time point) were defined as overlapped gene targets between m6A-seq and m6A-CLIP-seq. Ythdf2-regulated genes were defined as overlapped gene targets between the lists of the top 20% upregulated genes in both ythdf2 knockout and MO-injected samples. The most stringent Ythdf2 target genes at 4 h.p.f. (135) were defined in the main text, as overlapped genes of methylated genes at 4 h.p.f. (3,237) and Ythdf2-regulated genes at 4 h.p.f. (876). All the raw data and processed files have been deposited in the Gene Expression Omnibus (http://www.ncbi.nlm.nih.gov/geo) and accessible under GSE79213. A summary of sequenced samples and processed FPKM data are included as Supplementary Data 2. One set of representative experiment results from at least two independent experiments were shown where applicable. Quantitative reverse-transcription PCR (RT–qPCR) was performed to assess the relative abundance of mRNA. All RNA templates used for RT–qPCR were pre-treated with on-column DNase I digestion in the purification step. RT–qPCR primers were designed to span exon-exon junctions to only detect mature mRNA. RT–qPCR was performed by using SuperScript III one-step RT–PCR system (Thermo Fisher) with 50–100 ng total RNA template. Actb1 was used as an internal control as it showed relative invariant expression during the studied time period according to pilot RT–qPCR data. P values were determined using two-sided Student’s t-test for two samples with equal variance. *P < 0.05; **P < 0.01; ***P < 0.001. The sequences of primers used in this study are listed below: actb1: forward 5′-CGAGCAGGAGATGGGAACC-3′, reverse 5′-CAACGGAAACGCTCATTGC-3′; buc: forward 5′-CAAGTTACTGGACCTCAGGATC-3′, reverse 5′-GGCAGTAGGTAAATTCGGTCTC-3′; zgc:162879: forward 5′-TCCTGAATGTCCGTGAATGG-3′, reverse 5′-CCCTCAGATCCACCTTGTTC-3′; mylipa: forward 5′-CCAAACCAGACAACCATCAAC-3′, reverse 5′-CACTCCACCCCATAATGCTC-3′; vps26a: forward 5′-AAATGACAGGAATAGGGCCG-3′, reverse 5′-CAGCCAGGAAAAGTCGGATAG-3′; tdrd1: forward 5′-TACTTCAACACCCGACACTG-3′, reverse 5′-TCACAAGCAGGAGAACCAAC-3′; setdb1a: forward 5′-CTTCTCAACCCAAAACACTGC-3′, reverse 5′-CTATCTGAAGAGACGGGTGAAAC-3′; mtus1a: forward 5′-TGGAGTATTACAAGGCTCAGTG-3′, reverse 5′-TTATGACCACAGCGACAGC-3′; GFP: forward 5′-TGACATTCTCACCACCGTGT-3′, reverse 5′-AGTCGTCCACACCCTTCATC-3′.

PARSIPPANY, NJ--(Marketwired - Feb 21, 2017) - GAF, North America's largest roofing manufacturer, is proud to introduce a new non-halogen polyisocyanurate insulation: EnergyGuard™ NH Polyiso Insulation Board. With this product introduction, GAF is the first roofing manufacturer to offer a full line of Red List Free roofing assemblies across their asphaltic and single ply product lines. The development of GAF EnergyGuard™ NH Polyiso Insulation Board supports the company's commitment to providing architects, contractors, and building owners with affordable products that help them meet their sustainable and environmental design goals. EnergyGuard™ NH Polyiso Insulation Board has all the inherent properties and performance factors polyiso insulation is known for, including one of the highest insulation values and a UL Class A roofing fire rating, but does not contain any halogenated flame retardants. "There is increasing interest in Red List free products," said Jeanine K. Mulcahy, Product Manager -- Insulation and Fastener Systems for GAF. "The development of EnergyGuard™ NH Polyiso Insulation Board is one more indication that architects and contractors who share our commitment to sustainable design can count on GAF for environmentally preferable products." Transparent and Red-List Free Recognizing that numerous jurisdictions have enacted legislation restricting the use of one or more chemical flame retardants, GAF has taken the proactive step of replacing TCPP with a non-halogen material that offers the same flame-retardant properties. As a result, GAF EnergyGuard™ NH Polyiso Insulation Board is one of the few polyisocyanurate roofing solutions with a Declare label designated as Red List Free. "It's exciting to see this new Red List Free insulation available. We're seeing more and more product options available to project teams pursuing Living Building Challenge certification," said James Connelly, Director, Living Product Challenge at International Living Future Institute. GAF EnergyGuard™ polyiso is the company's premier line of insulation boards designed for use in practically any low-slope roofing application, including BUR, mod bit, and single-ply systems. EnergyGuard™ NH Polyiso Insulation Boards offers a high insulation value with an excellent "LTTR" value compared to any other FM Class I rated product of equivalent thickness. It also meets FM 4450/4470 and UL1256/790. About GAF: Founded in 1886, GAF is the largest roofing manufacturer in North America. The Company is an operating subsidiary of Standard Industries. GAF products include a comprehensive portfolio of steep-slope and commercial roofing systems, which are supported by an extensive national network of factory-certified contractors.

A new strategy has been developed using peptides with amino and carboxylic functional groups as passivating ligands to produce methyl ammonium lead bromide (CH NH PbBr ) perovskite nanocrystals (PNCs) with excellent optical properties. The well-passivated PNCs can only be obtained when both amino and carboxylic groups are involved, and this is attributed to the protonation reaction between NH and COOH that is essential for successful passivation of the PNCs. To better understand this synergistic effect, peptides with different lengths have been studied and compared. Due to the polar nature of peptides, peptide-passivated PNCs (denoted as PNCs ) aggregate and precipitate from nonpolar toluene solvent, resulting in a high product yield (≈44%). Furthermore, the size of PNCs can be varied from ≈3.9 to 8.6 nm by adjusting the concentration of the peptide, resulting in tunable optical properties due to the quantum confinement effect. In addition, CsPbBr PNCs are also synthesized with peptides as capping ligands, further demonstrating the generality and versatility of this strategy, which is important for generating high quality PNCs for photonics applications including light-emitting diodes, optical sensing, and imaging.

Recently, organic–inorganic hybrid perovskite materials have drawn great attention for their outstanding performance in high-efficiency solar cells. Successful synthesis has been realized either in solution-based chemical deposition or vapor deposition. However, conflicts have never ceased among quality control, growth rate, process complexity, and instrument requirement, which have limited their development toward real applications. In this work, the first electrochemical fabrication of perovskite toward high-efficiency and scalable perovskite solar cells (PSCs) is established. The morphology and crystallization of the CH NH PbI film can be effectively controlled by simply modulating a few physical parameters. A detailed study on its optoelectronic properties reveals significantly improved film quality and interfacial conditions. Aided by this, the total process does not require standard annealing, which greatly reduces the total growth time from hours to minutes. Up to now, an efficiency of 15.65% has been achieved in planar PSCs under 1 sun AM 1.5 condition, with small hysteresis and efficiency loss under longtime exposure to air. Moreover, high efficiency (10.45%) can be easily attained for large cells (2 cm2). This result will hopefully facilitate research for applicable high-efficiency PSCs and other multicomponent materials as well.
