Feds fund concept for cheaper, better titanium made in US

A Case Western Reserve University proposal for a low-cost, energy-efficient method to extract the strategic metal titanium from ore has been selected by the U.S. Department of Energy's Advanced Research Projects Agency-Energy ...

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.
