Image showing a sphere made up of slices. The sphere's north pole that pointed towards the camera is located at the leftmost rim. The meridians connecting both poles are visible as brighter dots. Closer inspection shows that the horizontal north-south axis is 11% longer than the vertical (equatorial) diameter. This effect is an artifact caused by the necessary tilt of the Lorentz-contracted sphere relative to the light source to ensure proper illumina- tion. The meridians appear discontinuous because they are almost in line of sight seen from the camera.

Curious consequence of special relativity observed for the first time in the lab

Real 3D objects appear rotated rather than contracted when moving at relativistic speeds

Image illustrating four different stages of turbulent mixing between two fluids. The different fluids are represented by cool and warm colours, and the four stages are set against a background of swirls and bubbles

Simulations could take just a few hours rather than several days

Photo of the sneeze simulator being tested in the laboratory. The simulator is a three-dimensional model that incorporates a representation of the nasal cavity as well as other parts of the human upper respiratory tract, and it's shown here as an apparatus inside a transparent box, bathed in green light and emitting a burst of aerosols while being tended by a person in a lab coat
