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.

The tree people in the Lord of the Rings, the ants, can get around by walking.

But for real trees, well, it's harder to uproot.

Because it's a sace-cell organism, literally rooted into the ground, it is unable to leave

and go elsewhere.

Mario Peasendorfer, a behavioral ecologist at the Cornell Lab of Ornithology.

When a tree first starts growing in a certain area, it's likely that the climactic envelope,

so the temperature, humidity, soil, composition and so on, suits it because it otherwise would be unable to grow from a seedling.

But as it ages, these conditions may change and the area around it may no longer be suitable for its offspring.

And if that happens, walnuts, hazelnuts, chestnuts, oaks, pines, many rely exclusively on so-called scatter hoarders, like birds,

to move their hefty seeds to new locales. Many members of the family Corvide, the crows, jays, and magpies

are scatter hoarders, meaning that they like to store food for the winter that they then subsequently

retrieve. Or a knot. And when they do forget something, a seedling has a chance to grow, sometimes a good

distance away.

The Clark's Nutcracker, which is found in alpine regions of Western North America, is definitely

the rock star among the scatter hoarding corvets. They hide up to 100,000 seeds per year,

up to 30 kilometers away from the seed source, and I have a very tight symbiotic relationship
