AI technology produces clear images of thick biological samples without additional hardware.
Concepts and simulations demonstrating deep learning-based aberration correction. Credit: Nature Communications (2025). DOI: 10.1038/s41467-024-55267-x Depth degradation is a problem that biologists are familiar with. The deeper you examine the sample, the blurrier the image becomes. C. elegans embryos and pieces of tissue are only tens of microns thick, but when the instrument peeks past the top layer, light bending causes…

Researchers use lasers to grow biological tissue in the lab to produce microfilaments
Filament optical 3D bioprinters can be used to create aligned tissue structures. Credit: Zurich University of the Arts / Samuel Thalmann Pioneer Fellow Hao Liu uses lasers to generate microfilament structures to grow living tissue in the lab for research and medical purposes, from muscle tissue to cartilage. He is currently working on getting this technology ready for the market.…

Engineers create chip-based tractor beam for biological particles
Integrated OPA tweezers concept. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-52273-x Researchers at MIT have developed a small chip-based “tractor beam” similar to the one seen on the Millennium Falcon in the “Star Wars” movies. This could one day help biologists and clinicians study DNA, classify cells, and investigate disease mechanisms. . The study is published in the journal Nature Communications.…

Biological wonders of the ocean floor are being mined to make commercial products – here are the risks
Deep-sea shrimp live in the dark, deep waters of the Pacific Ocean. Credit: NOAA Thousands of genes from deep sea marine life are being used to create new products ranging from medicines to cosmetics. Genes are segments of DNA that provide instructions for making other molecules essential to the structure and function of living organisms. A paper we recently published…
