Study confirms hairpin vortices in supersonic turbulence

The turbulence that occurs in the low-pressure region behind a rocket traveling at supersonic speeds is complex and not well understood. In the first experimental study of its kind, researchers at the University of Illinois ...

Big energy savings for tiny machines

Inside all of us are trillions of tiny molecular nanomachines that perform a variety of tasks necessary to keep us alive.

Molecular hairpin structures make effective DNA replicators

The evolution of cells and organisms is thought to have been preceded by a phase in which informational molecules like DNA could be replicated selectively. New work shows that hairpin structures make particularly effective ...

Dissecting the brain's primary developmental engine

(Phys.org) —Last month, researchers reported the creation of the first primitive brain-like structures made from human stem cells. To create the complex morphology of these cerebral organoids, cells within a proliferating ...

Undoing a hairpin doubles gene activity

Male fruit flies have one X chromosome per cell, females have two. So genes on the male X must work twice as hard to produce the same amount of protein as its female counterparts. An LMU team has found a new switch involved ...

Hairpin turn: Micro-RNA plays role in wood formation

For more than a decade, scientists have suspected that hairpin-shaped chains of micro-RNA regulate wood formation inside plant cells. Now, scientists at NC State University have found the first example and mapped out key ...
