Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

Tired of having to reach for your night vision goggles when you want to track someone's heat signature after dark.

Well, biotech may someday come to the rescue for all of you aspiring spies.

Because researchers have developed an injectable nanoscale antenna, which they've used to allow mice to see beyond their normal visual spectrum and into the infrared.

The work appears in the journal's cell.

Like all mammals, we humans are only able to see light in the visible spectrum, which includes all of the colors of the rainbow.

That limitation is due to the photoreceptors in our eyes, being only able to detect radiation with a wavelength of around

400 to 700 nanometers, which means we can't see infrared and near infrared light, which has

wavelengths a little bit longer. And that got scientists thinking.

So we always are curious whether we can use any method or technique to allow us to be able

to see near infrared or infrared light. Tian Shi of the University of Science and Technology of China.

He reached out to his colleague, Gong Hong,

at the University of Massachusetts Medical School, who engineered a teeny tiny device, which he

calls an up-conversion nanoparticle. We actually developed nanoparticles, so-called up-conversion

nanoparticles. That actually can effectively be active by this neon infrared light.
