Custom polymer structures can now be 3D printed inside living cells using laser-based fabrication, opening paths to intracellular sensors, cell tracking tags, and embedded microlasers.

Scientists have crossed a startling new frontier in bioengineering: they can now fabricate intricate three-dimensional ...

Traveling to space is brutal on the body. Spaceflight can cause astronauts’ bones to lose density, their brain and eye nerves to swell, and their genes to change expression. Research suggests spending ...

According to Einstein’s theory of relativity, time passes more slowly in space. As a result, astronauts would experience a delay in aging. However, scientists found that space travel may have the ...
