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.

During intense exercise, sprinting, for example, your body breaks down glucose and produces what's called lactate.

That substance can build up faster than it can be further processed.

If your idea of a workout is running to the refrigerator during commercials,

you probably associate the lactate buildup with a burning in your muscles. But for well-conditioned

athletes, excessive lactate means muscle fatigue and diminished performance. So athletes would

like to know their actual lactate levels during training and competition. Blood tests are one way to measure lactate

levels, but are not practical in the middle of a game or race. So a goal has been to find a way to

measure lactate in saliva to monitor muscle endurance, which researchers at Palo Alto Research Center,

known as Park, and the University of California San Diego say they've achieved.

Working with Flexible Hybrid Electronics Group NextFlex, the team developed a flexible plastic mouthguard laden with sensors that can continuously monitor lactate concentrations

and saliva. The mouthguard's batteries are rechargeable wirelessly, and the device can use

low-power Bluetooth to send information to smartphones, watches, and other electronic devices.

Park scientists presented their work at the recent semi-conference on electronics manufacturing in Monterey.

Park, which is part of Xerox and best known for its pioneering work in PCs, printing, and computer networking in the 1970s,
