Early Birds of the Future: Earlier, but Still Too Late?

Birds need to adapt to climate change, but evolution is a slow process. Model species such as the great tit are an indispensable yardstick for our ability to predict the impact of climate change on nature. Using innovative methods, a team from the Netherlands Institute of Ecology (NIOO-KNAW) took a ...

Scientists Discover Clues to Aging and Healing from a Squishy Sea Creature

Insights into healing and aging by those who studied how a tiny sea creature regenerates an entire new body from only its mouth. The researchers sequenced RNA from Hydractinia symbiolongicarpus, a small, tube-shaped animal that lives on the shells of hermit crabs. Just as the Hydractinia were ...

Virus-Like Transposons Wage War on the Species Barrier

Scientists have known for decades that genes can be transferred from one species to another, both in animals and plants. However, the mechanism of how such an unlikely event occurs remained unknown. Now, researchers identify a vector of horizontal gene transfer (HGT) in worms. The findings could ...

A Jaw-Dropping Conundrum: Why Do Mammals Have a Stiff Lower Jaw?

The lower jaws of lizards, birds, fish and even dinosaurs are comprised of multiple bones per side. Yet mammals diverged from all other vertebrates and settled on just one bone, repurposing the extra bones into a more elaborate inner ear, perhaps the better to hear. The single bone per side, fused ...
