Journal Club: Ancient fish moving to land used their tails as crutches

The evolution from fish living in water to vertebrates living on land was one of the most pivotal moments in the history of the animal kingdom. Now scientists using robot fish suggest that these ancient pioneers may have used their … Continue reading

Engineered nanomaterials grow smaller and stronger

Materials scientists have a few options for making lighter, yet stronger materials: improve the strength, lower the density, or both. But at a certain point, it’s tough to get much much stronger without added bulk. Jens Bauer and his colleagues … Continue reading

Researchers flesh out new model describing tissue mechanics

Enough tension will do anything in. Cells grown in a constrained environment, in a matrix or on a platform, have a bad habit of breaking due to their own strength. Though frustrating for those working in regenerative medicine, which seeks … Continue reading

Smaller nano-channel weighs with attogram precision

The mass of nanoparticles as small as 10 nanometers in diameter can be determined with attogram precision by measuring the oscillations of a cantilevered nanobeam supporting the particles, researchers report in the Proceedings of the National Academy of Sciences. Furthermore, … Continue reading

Fatigue-resistant amorphous metals rely on zigzag cracks

Amorphous metals whose atomic arrangements resemble those of a liquid more than a crystal are often exceptionally strong when compared to their crystalline counterparts, but they are typically much less resistant to fatigue, greatly hampering their use. Now scientists find … Continue reading
