Could permanent magnets protect astronauts from solar storms?
Shielding astronauts from the deadly radiation they face is a central challenge for any designer of a deep-space crewed mission. Even relatively low levels of exposure over long periods can lead to everything from central nervous system damage to cancer. But current solutions, su

'Their story is our story': Pigeons and humans, 3,500 years together
They have been our meat and our messengers, a source of fertilizer and a religious symbol: while pigeons are now mostly reviled as dirty city pests, they long played an important role in human society.

Ribosome-based gene circuit lets cells read six signals and trigger responses
The molecular machinery that normally builds proteins inside cells has now taken on a new role as a "switch." A research team at POSTECH (Pohang University of Science and Technology) has developed a new 'RNA-based smart gene circuit' platform that can simultaneously read multiple
