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.

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

Imagine getting screened for early stage lung cancer, simply by taking a deep breath from an inhaler and then peeing into a cup.

Sangita Baccia, a professor of health sciences and engineering at MIT, described how that might be possible in a TED talk she gave in 2016. What if you had a detector that was so small that it could circulate in your body,

find the tumor all by itself, and send a signal to the outside world? It sounds a little bit like

science fiction, but actually nanotechnology allows us to do

just that. Bacchia's idea was to invent non-toxic nanoprobes that doctors could put inside your

blood or lungs or gut to detect tiny tumors when they're easier to treat before they grow big

enough to spread throughout the body

and damage vital organs. I dream that one day, instead of going into an expensive screening

facility to get a colonoscopy or a mammogram or a pap smear, that you could get a shot,

wait an hour, and do a urine test on a paper strip.

In 2017, Bataia's team reported a proof-of-concept experiment in nature biomedical engineering

that demonstrated nanoprobes like this, working to detect early stage ovarian cancer in mice.

And now the group has refined this technology further to create a screening test for lung

cancer that is more sensitive than the CT scans used today. The team of Harvard and MIT
