Extinct kitten-sized hunter discovered

A Case Western Reserve University student and his mentor have discovered an ancient kitten-sized predator that lived in Bolivia about 13 million years ago—one of the smallest species reported in the extinct order Sparassodonta.

Nanoparticle pinpoints blood vessel plaques

A team of researchers, led by scientists at Case Western Reserve University, has developed a multifunctional nanoparticle that enables magnetic resonance imaging (MRI) to pinpoint blood vessel plaques caused by atherosclerosis. ...

A new species of horse, 4.4 million years old

Two teams of researchers, including a scientist from Case Western Reserve University, have announced the discovery of a new species of fossil horse from 4.4 million-year-old fossil-rich deposits in Ethiopia.

Researchers report nanoscale energy-efficient switching devices

By relentlessly miniaturizing a pre-World War II computer technology, and combining this with a new and durable material, researchers at Case Western Reserve University have built nanoscale switches and logic gates that operate ...

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.

MOND predicts dwarf galaxy feature prior to observations

A modified law of gravity correctly predicted, in advance of the observations, the velocity dispersion—the average speed of stars within a galaxy relative to each other—in 10 dwarf satellite galaxies of the Milky Way's ...

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 ...

Metal-free catalyst outperforms platinum in fuel cell

Researchers from South Korea, Case Western Reserve University and University of North Texas have discovered an inexpensive and easily produced catalyst that performs better than platinum in oxygen-reduction reactions.
