The intricate process of mitosis—a cell splitting into two identical daughter cells—plays a pivotal role in sustaining life. Many scientists study this process to understand what’s needed for it to progress normally and why it sometimes goes awry, such as in cancer. During their research, the scientists often create eye-catching images and videos, and we showcase some of those visuals here.Continue reading “Slideshow: Mitosis Masterpieces”

It’s the spookiest time of the year! To celebrate Halloween, we’re showcasing scientific images that capture the spirit of the holiday, from a brain shaped like a bat to protein “cobwebs” in a quail embryo. Check out our image and video gallery for even more scientific photos, illustrations, and videos.
Most cells are naturally colorless, which is why scientists often use fluorescent tags and other tools to color cell structures and make them easier to study. (Check out the Pathways imaging issue for more on scientific imaging techniques). Here, we’re showcasing cell images that feature shades of blue. Visit our Image and Video Gallery for additional images of cells in all the colors of the rainbow, as well as other scientific photos, illustrations, and videos.
Have you ever wondered what creates striking images of cells and other tiny structures? Most often, the answer is microscopes. Many of us have encountered basic light microscopes in science classes, but those are just one of many types that scientists use. Check out the slideshow to see images researchers have captured using different kinds of microscopes. For even more images of the microscopic world, visit the NIGMS Image and Video Gallery.Continue reading “A Focus on Microscopes: See Eye-Catching Images”
The tiny roundworm Caenorhabditis elegans is one of the most common research organisms—creatures scientists use to study life. While C. elegans may seem drastically different from humans, it shares many genes and molecular pathways with us. Viewed with a microscope, the worm can also be surprisingly beautiful. Aside from the stunning imagery, these examples from our Image and Video Gallery show how C. elegans helps scientists advance our understanding of living systems and find new ways to improve our health.
This C. elegans has been infected with microsporidia (purple), parasites closely related to fungi. The yellow shapes are the worm’s gut cells, and the blue dots are nuclei. Some microsporidia can infect people, so studying the parasites in worms could help researchers devise strategies to prevent or treat infections.Continue reading “Cool Images: Wondrous Worms”
Some bacteria benefit us as part of our microbiome—the vast collection of microorganisms that live in and on our bodies—while others can make us sick. Whether helpful or dangerous, bacteria can appear colorful and striking under a microscope. These photos provide just a small peek into the incredible diversity of these microbes.
This floral pattern emerged when a researcher grew two strains of bacteria—Acinetobacter baylyi (red) and Escherichia coli (green)—together for 2 days in a petri dish. A. baylyi are found in soil and typically don’t pose a threat to humans, although some strains can cause infections. E. coli normally live in the intestines of people and animals. Most strains are harmless, but some can cause food poisoning or other illnesses.Continue reading “Cool Images: Bewitching Bacteria”
Whether you’re teaching remotely, attending classes virtually, or just participating in online meetings, video calls have likely become part of your daily life. Eye-catching backgrounds can be a great way to add some fun to these calls and help protect your privacy. NIGMS has a collection of biology-themed backgrounds for use with video-call software such as Zoom and Microsoft Teams.
All of these backgrounds are scientific images from the NIGMS Image and Video Gallery, which contains even more options for you to download and use.
Wildlife photos can be truly stunning, and cute cat pictures are a cornerstone of the internet. But zooming in on the early lives of fish, insects, and worms can have equally wonderful results. Using powerful microscopes, researchers are revealing the complexity and beauty of animal development.
This image captures the spiral-shaped ovary of an anglerfish in cross section. Once matured, these eggs will be released in a gelatinous, floating mass. For some species of anglerfish, this egg mass can be up to 3 feet long and include nearly 200,000 eggs.Continue reading “Cool Images: Animal Development in Progress”
Spring brings with it a wide array of beautiful flowers, but the interior structures of plants can be just as stunning. Using powerful microscopes, researchers can peek into the many molecular bits and pieces that make up plants. Check out these cool plant images from our Image and Video Gallery that NIGMS-funded scientists created while doing their research.
In plants and animals, stem cells can transform into a variety of different cell types. The stem cells at the growing tip of this Arabidopsis plant will soon become flowers. Cellular and molecular biologists frequently study Arabidopsis because it grows rapidly (its entire life cycle is only 6 weeks), produces lots of seeds, and has a genome that’s easy to manipulate.Continue reading “Cool Images: The Hidden Beauty Inside Plants”
