“I keep messing up my curve balls,” she shouts, manically flicking her fingers across her phone screen to throw Poké Balls, the spherical tools used to catch Pokémon, the mission of the game.

The huge spherical chamber that hosted Sierra Space’s tests in July and August this year induced a vacuum and also simulated lunar temperatures and pressures.

This indicates that most of these highly star-forming galaxies are intrinsically spherical rather than disk-shaped.

In the new study, the researchers carefully inserted 1,200 pieces of fishing line -- one at a time -- through a thin, vertical slice of material with four pores that represent spherical grains of gravel.

The inner part of the machine rotates like a screw, combining the molecules, converting the structure of the plant material from spherical shapes to fibers.
