Cosmic rays help supernovae explosions pack a bigger punch

The final stage of cataclysmic explosions of dying massive stars, called supernovae, could pack an up to six times bigger punch on the surrounding interstellar gas with the help of cosmic rays, according to a new study led ...

What's a suborbital flight? An aerospace engineer explains

"Suborbital" is a term you'll be hearing a lot as Sir Richard Branson flies aboard Virgin Galactic's VSS Unity winged spaceship and Jeff Bezos flies aboard Blue Origin's New Shepard vehicle to touch the boundary of space ...

Research team turns up the heat on 3D printing inks

A process that uses heat to change the arrangement of molecular rings on a chemical chain creates 3D-printable gels with a variety of functional properties, according to a Dartmouth study.

Molecular switch enables photomechanical jumping of polymers

Jumping movement is commonly observed in nature, including for mammals, insects and the other land creatures; this fluid motion aims for rapid mobility, a faster arrival time at a destination over large obstacles and rough ...

How big is a 'fragment'?

When a drinking glass falls on the floor and breaks, the shards will vary in size from large to extremely small. For the broken glass of a bus shelter, the story is different: all fragments have roughly the same size. Researchers ...

Research uncovers missing physics in explosive hotspots

Research conducted on Lawrence Livermore National Laboratory's (LLNL) supercomputer Quartz highlights findings made by scientists that reveal a missing aspect of the physics of hotspots in TATB (1,3,5-trimamino-2,4,6-trinitrobenzene) ...
