A window into the body: New technique makes skin invisible
Researchers have developed a new way to see organs within a body by rendering overlying tissues transparent to visible light. The counterintuitive process—a topical application of food-safe dye—was reversible in tests with animal subjects, and may ultimately apply to a wide range of medical diagnostics, from locating injuries to monitoring digestive disorders to identifying cancers.
Common yellow food dye can make the skin of a mouse temporarily transparent, study finds
In H.G. Wells’ 1,897 science fiction novel, “The Invisible Man,” the protagonist invents a serum that makes the cells in his body transparent by controlling how they bend light.
More than 100 years later, scientists have discovered a real-life version of the substance: A commonly used food coloring can make the skin of a mouse temporarily transparent, allowing scientists to see its organs function, according to a new study published Thursday in the journal Science.
The breakthrough could revolutionize biomedical research and, should it be successfully tested in humans, have wide-ranging applications in medicine and health care, such as making veins more visible to draw blood.
Robots Are Coming to the Kitchen. What Does This Mean for Everyday Life?
Can automated restaurants still be community and cultural spaces, or will they become feeding stations for humans? These and other questions loom as new food tech reaches the market.
Scientists just made mice ‘see-through’ using food dye — and humans are next
A common food dye can turn the skin of living mice transparent, enabling researchers to peer inside the body without surgery.
This is the first time scientists have used the technique to visualize the tissues of living mice under the microscope. They used a food-safe dye, which can likely be found in snacks in your pantry, and several fundamental physics principles to render the mice see-through.
Seeing like a butterfly: Optical invention enhances camera capabilities
Butterflies can see more of the world than humans, including more colors and the field oscillation direction, or polarization, of light. This special ability enables them to navigate with precision, forage for food and communicate with one another. Other species, like the mantis shrimp, can sense an even wider spectrum of light, as well as the circular polarization, or spinning states, of light waves. They use this capability to signal a “love code,” which helps them find and be discovered by mates.
Inspired by these abilities in the animal kingdom, a team of researchers at the Penn State College of Engineering has developed an ultrathin optical element known as a metasurface, which can attach to a conventional camera and encode the spectral and polarization data of images captured in a snapshot or video through tiny, antenna-like nanostructures that tailor light properties. A machine learning framework, also developed by the team, then decodes this multi-dimensional visual information in real-time on a standard laptop.
The researchers have published their work in Science Advances.
Quantum-dot-enabled infrared hyperspectral imaging with single-pixel detection
Widely utilized across various industries such as chemistry, agriculture, and military, this technology relies on strategies like dispersive optics and narrow-band light filters.
However, limitations exist in these approaches. Additionally, the fabrication of large-scale InGaAs detector arrays poses challenges, necessitating the development of new experimental methods and algorithms to advance infrared hyperspectral imaging technology in terms of miniaturization and cost-effectiveness.
In a paper published in Light Science & Applications, a team led by Professor Baoqing Sun and Yuan Gao from Shandong University introduce a novel method for encoding near-infrared spectral and spatial data.

How much microplastic are you drinking? New tool can tell you in minutes
Micro-and nanoplastics are in our food, water and the air we breathe. They are showing up in our bodies, from testicles to brain matter. Now, University of British Columbia researchers have developed a low-cost, portable tool to accurately measure plastic released from everyday sources like disposable cups and water bottles.
