Electromagnetic device identifies cells by seeing how high they levitate

It looks like a magic trick: Cells at the bottom of a liquid medium begin levitating, then hovering at a particular height. With no physical contact, an invisible force directs certain cells to float up or down in unison, ...

3D particle-in-cell simulations demonstrate first true steady state in turbulent plasma

Plasma is a state of matter that emerges when a gas is heated to sufficiently high temperatures, prompting some electrons to become free from atoms. This state of matter has been the focus of many astrophysical studies, as ...

Bling, not brawn, gives some animals the edge in the mating game

New UNSW research confirms that in the battle for survival, some animals win not with brawn, but with bling, putting to bed a debate that has puzzled generations of scientists. The study is published in the journal Ecology ...
