Research Progress on Metal–Organic Frameworks by Advanced Transmission Electron Microscopy 5:01

Research Progress on Metal–Organic Frameworks by Advanced Transmission Electron Microscopy

Imagine trying to photograph a soap bubble with a blast of radiation: the picture might be sharp, but the subject vanishes first. That is the problem researchers face with these promising, fragile materials.

Development of doubled haploid inducer lines facilitates selection of superior haploid inducers in maize 3:05

Development of doubled haploid inducer lines facilitates selection of superior haploid inducers in maize

What if the plants used to create better maize could themselves be rebuilt from scratch? This study turns the breeding tool into a breeding target, and finds offspring that outperform their parents.

Improved Wound Healing and Skin Regeneration Ability of 3,2′-Dihydroxyflavone-Treated Mesenchymal Stem Cell-Derived Extracellular Vesicles 3:55

Improved Wound Healing and Skin Regeneration Ability of 3,2′-Dihydroxyflavone-Treated Mesenchymal Stem Cell-Derived Extracellular Vesicles

A healing cell may not need to be placed into a wound to help it. This study suggests that tiny packages released by specially treated cells can calm inflammation and help damaged skin close faster.

Predicting peak inundation depths with a physics informed machine learning model 4:00

Predicting peak inundation depths with a physics informed machine learning model

During a flood, the best physics-based forecasts can be too slow to guide same-day decisions. This study asks whether a faster learner can preserve the useful part: knowing where water will rise, and why.

Tailoring On-Surface Molecular Reactions and Assembly through Hydrogen-Modified Synthesis: From Triarylamine Monomer to 2D Covalent Organic Framework 3:41

Tailoring On-Surface Molecular Reactions and Assembly through Hydrogen-Modified Synthesis: From Triarylamine Monomer to 2D Covalent Organic Framework

A trace of hydrogen can decide whether a molecular layer grows into a large, connected network, or stops as separate pieces. Stranger still, the same effect can be used to make useful intermediate structures on purpose.

Geometric Morphometric Analysis of Mandibular Symphysis Growth between 12 and 15 Years of Age in Class II Malocclusion Subjects 4:02

Geometric Morphometric Analysis of Mandibular Symphysis Growth between 12 and 15 Years of Age in Class II Malocclusion Subjects

Orthodontic treatment can move teeth, but the bone at the front of the lower jaw sets a boundary. This study asks whether that boundary naturally reshapes during the teenage years, and finds a reason not to count on it.

Surface-Modified Piezoelectric Copolymer Poly(vinylidene fluoride–trifluoroethylene) Supporting Physiological Extracellular Matrixes to Enhance Mesenchymal Stem Cell Adhesion for Nanoscale Mechanical Stimulation 3:55

Surface-Modified Piezoelectric Copolymer Poly(vinylidene fluoride–trifluoroethylene) Supporting Physiological Extracellular Matrixes to Enhance Mesenchymal Stem Cell Adhesion for Nanoscale Mechanical Stimulation

A future bone graft might not need only the right cells. It may also need the right surface, and tiny vibrations that help those cells begin turning into bone.

Urine complement-related proteins in IgA nephropathy and IgA vasculitis nephritis, possible biomarkers of disease activity 3:15

Urine complement-related proteins in IgA nephropathy and IgA vasculitis nephritis, possible biomarkers of disease activity

A kidney biopsy gives doctors a snapshot of damage, but it carries risks. This study asks whether urine can reveal something more useful: whether kidney disease is active now, or quietly leaving lasting scars.

Eco-Friendly Semi-Interpenetrating Polymer Network Hydrogels of Sodium Carboxymethyl Cellulose/Gelatin for Methylene Blue Removal 4:15

Eco-Friendly Semi-Interpenetrating Polymer Network Hydrogels of Sodium Carboxymethyl Cellulose/Gelatin for Methylene Blue Removal

A soft, water-swollen material made from cellulose, gelatin, and citric acid can pull a stubborn blue dye out of polluted water, and still remove more than eighty-five percent of it after being used again and again.

Defining the ferroptotic phenotype of beta cells in type 1 diabetes and its inhibition as a potential antidiabetic strategy 3:26

Defining the ferroptotic phenotype of beta cells in type 1 diabetes and its inhibition as a potential antidiabetic strategy

In type 1 diabetes, insulin-making cells may not only be attacked by the immune system, they may also be destroyed by a chain reaction involving iron and damaged fats. Blocking that reaction helped preserve signs of pancreatic health in diabetic mice.

Go for zero tolerance: Cultural values, trust, and acceptance of zero-COVID policy in two Chinese societies 3:39

Go for zero tolerance: Cultural values, trust, and acceptance of zero-COVID policy in two Chinese societies

During the pandemic, some people saw strict controls as a shared shield, while others saw them as a personal burden. This study finds that the difference helped shape whether people accepted zero-COVID rules.

Integrating ICT in education: A scoping review of pre-service teachers’ ICT beliefs 4:11

Integrating ICT in education: A scoping review of pre-service teachers’ ICT beliefs

A classroom can be filled with modern technology and still teach in the old way. This review finds that what future teachers believe about technology may shape whether it actually changes learning.
