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.

Foldable white canes help the visually impaired navigate their surroundings.

But the guide sticks tactile nature offers only so much information.

The cane's user must manually find and avoid obstructions.

But new high-tech canes are on the horizon.

Last year, researchers in India tried to fill in some of the missing info with their experimental smart cane.

The device uses an attached ultrasonic transmitter and a sensor that vibrates the cane to warn its users when an obstacle is within three meters.

Students at the UK's Birmingham City University are developing a cane that can even identify acquaintances as they approach. Called the Explore

Mobility Cain, it includes an embedded digital camera that analyzes the faces of people walking by

and compares their images against the database stored on a memory card in the cane's handle.

If there's a facial recognition match, the cane alerts the user's smartphone via Bluetooth.

The phone then identifies the approaching person to the user via its speaker or earbuds.

The students are building a prototype they'll test later this year. The hurdles are

significant. Facial recognition is a tough problem, especially outdoors. But if the explorer works,

it could actually give the visually impaired a leg up on everyone else, especially those of us who
