Connecting Asia to the human dispersal story

When trying to understand early human migration, timing is everything. We know that humans migrated from the African savannahs through Asia and down into Australia, and this journey is seen as one of our greatest human accomplishments. But we still don't know exactly when we... click to read more

Studies of the bugs within: telling sickness from cure

Each of us carries intestinal gardens, where microbes process food for our own consumption. We evolved to benefit from this, but as our guests are selfish single-cell creatures, tense diplomacy was always needed. Since these bacterial communities in our gut play surprisingly large roles in... click to read more

For polar bears the cost of living is rising

A warming Arctic is causing reductions in sea ice thickness and increasing its drift speed. Compositional and dynamic changes in sea ice could have impacts on the ability of ice-dependent vertebrates to acquire and amass energy needed for maintenance, growth, and reproduction. Knowledge of how... click to read more

Gut microbes as a novel anti-aging intervention?

Ours is a world dominated by microbes. Diverse microbial communities colonize just about any available space, even deep within our bodies' cavities. Remarkably, every human being carries as many bacterial as human cells, leading us to question the very meaning of what constitutes a human.... click to read more

Children Prefer the Real Thing to Pretending

Pretend-play is a favorite pastime for American children. They mentally transform the here and now, preparing pretend meals in toy kitchens, frolicking around on fake horses, and feeding baby dolls with plastic bottles. By age 4, children spend approximately 20% of their waking hours engaged... click to read more
