Evolution of diverse sex-determining mechanisms in mammals

Scientists historically have argued that evolution proceeds through gradual development of traits. But how can incremental changes apply to the binary switch between two sexes, male or female? Researchers at Case Western ...

Researchers identify two new ancient mammals in Bolivia dig

Researchers at Case Western Reserve University and two other universities have discovered the 13-million-year-old fossils of a pair of new species of extinct hoofed mammals known as "litopterns" from a site in Bolivia.

Full-length serotonin receptor structure seen for first time

A team of researchers from Case Western Reserve University School of Medicine have used Nobel prize-winning microscope technology to see full length serotonin receptors for the first time. The tiny proteins—approximately ...

Signal gradients in 3-D guide stem cell behavior

Scientists know that physical and biochemical signals can guide cells to make, for example, muscle, blood vessels or bone. But the exact recipes to produce the desired tissues have proved elusive.

Research team identifies new mechanism for protecting DNA

Researchers from Case Western Reserve University have identified a new mechanism by which a protein known for repairing damaged DNA also protects the integrity of DNA by preserving its structural shape.

Understanding the 'deep-carbon cycle'

New geologic findings about the makeup of the Earth's mantle are helping scientists better understand long-term climate stability and even how seismic waves move through the planet's layers.
