Punflay introduces another dissection app - Rat Dissection for the iPad. Back by popular demand, Punflay is adding another dissection app to its existing line-up of educational iPad apps. This time, students can experience a virtual dissection of a rat. Just like the award-winning app, Frog Dissection, Rat Dissection for the iPad has been designed for middle and high school students. The content for the app has been validated by subject matter experts to ensure accuracy. It’s a great substitute for the real thing and will fit perfectly in the science curriculum. Educators and students will find this very green app a blessing in the classroom. Users can get a feel for dissecting a rat on the iPad without ever inflicting any harm on the animal. The app walks you through a series of steps on how to dissect a rat. All you have to do is to simply follow the written instructions along with voice-over to dissect and explore the rat’s internal organs. Besides a virtual chloroformed specimen, Rat Dissection comes with all the dissection tools. The organs are all presented as 3D images. Users can tap on the individual organs to see what they look like from different angles. Detailed information on the organs is provided to help the student learn about their structure and function. Key Features: •Vivid 3D images of rat’s internal organs •Step-by-step instructions with voice over •Accurate simulation of the wet lab dissection procedure •Content validation by subject matter experts For those of you who haven’t tried our very popular app Frog Dissection, the following will give you an idea about how the app is popular among educators and students. If this is any indication, Rat Dissection is sure to be equally welcome in the classroom! The following are some schools that are either considering the use of Frog Dissection or are using it in the classroom now.

Molecule World A modern molecular visualization app for iPhone, iPad, and Mac. Molecule World is back — completely redesigned for Apple's modern ecosystem. Developed, in part, with funding from the National Science Foundation* and recognized for its contributions to science education, Molecule World has been rebuilt from the ground up as a single, unified app for iPhone, iPad, and Mac (via Mac Catalyst). The new version pairs high-quality molecular visualization with a streamlined experience that follows you across every device. Explore Molecular Structures in 3D Students, educators, and researchers can interactively explore proteins, DNA, RNA, and small molecules in a fully three-dimensional environment. Rotate, zoom, and pan through structures with smooth, high-quality rendering built for clarity and scientific understanding. Bring In Structures From the Major Databases Open files you already have, or fetch structures right inside the app — search the Protein Data Bank, PubChem, and NCBI by ID or keyword and have them download and open in seconds. Connect Sequences to Structure and Function on iPad and Mac The sequence viewer (iPad & Mac) makes it easy to see the number and kind of sequences in a structure — protein, DNA, and RNA — along with its heterogens: modified amino acids and nucleotides within a sequence, and external organic and inorganic molecules such as ligands and ions. Each sequence is colored to match your current view. Powerful Visualization Tools - Smooth, interactive 3D — rotate, zoom, and pan - Multiple representation styles: ball-and-stick, space-filling, tubes, ribbon/cartoon, molecular surfaces, and wire mesh - Focused selections — show just proteins, nucleic acids, ligands, backbones, or alpha-carbon traces - Scientific color schemes — by element, chain, residue, secondary structure, charge, hydrophobicity, and B-factor - Clear, context-aware legends that explain exactly what you're looking at Designed for Education and Discovery Molecule World is used in classrooms and laboratories to support teaching in structural biology, chemistry, and molecular science. Educators can illustrate key concepts — protein folding, molecular interactions, and the structure of DNA and RNA — with visuals students manipulate themselves. Built for the Apple Ecosystem One app runs natively on iPhone, iPad, and Mac. Optional iCloud support keeps your library of structures — and your place in them — in sync across all your devices. Built for What's Next This release lays the foundation for upcoming features, including enhanced analysis tools, richer educational workflows, and professional research capabilities. *NSF awards IIP 1315426 and DUE 2055036 Molecule World is developed by Digital World Biology LLC.
