Recapitulating the complexity of human organs in vitro would accelerate drug discovery and enable personalized treatments. By combining different types of liver cell from donor tissues, in vitro models of a liver region that mirror some of the organ’s main structures and functions can be assembled, getting closer to reproducing mini livers in vitro.

Viral DNA that is usually dismissed when sequencing the human genome could help to uncover useful information about complex diseases.

Numerical simulations provide a mechanism that explains how celestial objects such as stars and galaxies can generate ordered, macroscopic magnetic fields. The mechanism arises from turbulence — chaotic changes in the pressure and velocity of fluid — and avoids a physical effect that hinders other proposed systems from explaining observed ordered fields.

Conventional benchmarks are becoming less effective at assessing AI performance, but a multi-disciplinary test has set AI systems a fresh challenge.
