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.

Honeybees are the charismatic micro fauna of the pollination world.

But flies, bumblebees, butterflies and moths, they all pollinate too, with varying degrees of success.

The poorer ones are technically referred to as inefficient pollinators.

Those that do visit but transfer very little pollen in their visit.

Florian Schistel, an evolutionary biologist at the University of Zurich.

Schistel and his colleague grew field mustard plants, and they exposed them to two types of pollinators,

efficient bumblebees and inefficient hoverflies. After just 11 generations,

they found that the plants visited by bumblebees were taller, twice as fragrant, and reflected

more UV light, a visual signal for bees. And those factors made the progeny even more attractive

to bumblebees at the end of the experiment, a sign the plants had adapted to their pollinators'

preferences. But the plants that got a flyby from the flies, they grew shorter, less fragrant,

and actually adapted to do more self-pollination, because hoverflies are lousy pollinators.

The studies in the journal Nature Communications. So with honeybees in peril,

what happens if we lose them? This will trigger an evolutionary response in the plants.

For example, if flies take over as more important pollinators as they used to be in the past,

then very likely will have some evolutionary change going on.
